FIELD OF THE INVENTION
[0002] [0002] The present invention relates to oral treatment devices suitable for domestic use to provide a beneficial effect to a mammal's oral cavity. BACKGROUND OF THE INVENTION
[0003] [0003] In addition to regular dental examinations by professionals, daily oral hygiene is generally recognized as an effective preventive measure against the onset, development, and / or exacerbation of periodontal disease, gingivitis and / or tooth decay. Unfortunately, however, even the most meticulous individuals dedicated to thorough brushing and flossing often fail to reach, detach and remove food particles, plaques or biofilms found deep in the gums and / or between teeth. Most individuals perform dental cleaning with professionals twice a year to remove tartar deposits.
[0004] [0004] For many years, products have been designed to facilitate simple cleaning of teeth done at home, although for now a single device that is simple to use and that cleans all surfaces of a tooth and / or gingival or subgingival areas simultaneously is not available. The conventional toothbrush is widely used, although it requires a significant amount of energy to be effective and, in addition, a conventional toothbrush does not properly clean the interproximal areas of the teeth. The cleaning of the areas between the teeth currently requires the use of dental floss, toothpick or some other additional device besides the toothbrush.
[0005] [0005] Electric toothbrushes have achieved wide acceptance and although they reduce the energy required to use a toothbrush, they are still inadequate to ensure interproximal cleaning of teeth. Oral irrigators to clean the interproximal area between teeth are known. However, these devices have a single jet that must be directed to the precise interproximal area involved in order to remove debris. Therefore, these water pump type cleaners typically have significant value for teeth that have orthodontic appliances that often trap large particles of food. It will be understood that if debris and plaques are to be removed from the teeth, a combination of several devices must currently be used, which is extremely time-consuming and inconvenient.
[0006] [0006] In addition, to make these practices and devices effective, a high level of consumer adherence to techniques and / or instructions is required. User-to-user variation in time, cleaning / treatment formula, technique, etc., will affect teeth cleaning.
[0007] [0007] The present invention improves one or more of the disadvantages mentioned above with existing oral hygiene devices and methods, or at least provides an alternative technology that is advantageous over the known technology and can also be used to improve a harmful condition or optimize the cosmetic appearance of the oral cavity. SUMMARY OF THE INVENTION
[0008] [0008] The invention is a device for directing a liquid on a plurality of surfaces of a mammal's oral cavity, the device including a handle, a neck and a head. The cable includes first and second ports located at the proximal end thereof to receive the liquid from the liquid source, and first and second channels connected to the ports and arranged longitudinally through the cable to carry the liquid through the cable to the neck of the device. The neck includes the first and second channels to carry the liquid through the neck to the head. The head includes a cleaning component comprising a chamber to hold the liquid close to the plurality of surfaces, where the internal space or volume of the chamber is defined and bounded by proximal and distal sealing membranes, first and second internal side walls that extend longitudinally between the first and second sealing membranes, and an inner base wall that extends horizontally between the first and second internal side walls and longitudinally between the proximal and distal sealing membranes. The internal side walls include a plurality of openings, through which the liquid is directed to the surfaces of the oral cavity. The device further includes a first pipe to contain a first portion of the liquid and supply the first portion to the chamber through the openings of the first inner side wall and a second pipe to contain a second portion of the liquid and supply the second portion to the chamber through the openings of the second internal side wall. The device further includes a first port for transporting the first portion of liquid to and from the first pipe, a second port for transporting the second portion of liquid to and from the second pipe; and means for providing an effective seal of the device within the oral cavity.

[0040] [00040] The terms "fluid (s) and" liquid (s) "are used interchangeably in the present invention. As used herein, fluids or liquids may include gases or other particles and / or solids held there.
[0041] [00041] The terms "reciprocating liquid (s)" and "reciprocating liquid (s)" are used interchangeably in the present invention. For use in the present invention, both terms mean switching the flow direction of the liquid (s) back and forth over the surfaces of a mammal's oral cavity from a first flow direction to a second flow direction. opposite the first flow direction.
[0042] [00042] "Cleaning component" means a component that cleans and / or treats teeth, gums and other oral tissue. "Cleaning fluid" means a fluid that cleans and / or treats teeth, gums and other oral tissue.
[0043] [00043] By "effective adjustment or sealing", it is understood that the level of sealing between the device to direct the liquid to and over the plurality of surfaces in the oral cavity is such that the amount of liquid leakage from the device into the cavity during use is low enough to reduce or minimize the amount of liquid used to maintain user comfort, for example, to prevent gagging or pharyngeal reflex. Without limitation, pharyngeal reflex is understood as a reflex muscle contraction (that is, it is not an intentional movement) of the posterior part of the throat caused by stimulation of the posterior part of the soft palate, pharyngeal wall, tonsillar area or base of the tongue, designed to be a protective movement that prevents foreign objects from entering the pharynx and airways. There is variability in the pharyngeal reflex between individuals, for example, which areas of the mouth stimulate it. In addition to the physical causes of the pharyngeal reflex, there may be a psychological element to this, for example, people who are afraid of choking can easily vomit when something is put in the mouth.
[0044] [00044] For use in the present invention, the term "means for transporting the liquid" includes structures through which the liquid can pass or be transported through the systems and devices described herein and includes, without limitation, passageways, conduits, tubes, doors , portals, channels, ducts, pipes and pipes. These means for transporting liquids can be used in devices for providing fluid reciprocation and in devices for directing liquids to and over the surfaces of the oral cavity. These means of transport also supply liquid to the device for directing liquids and supply liquid to the reciprocal means from a reservoir to contain liquid. The means of transport can also supply liquid from a base unit to a liquid reservoir contained within the hand device. Described herein are methods, devices and systems useful for providing a beneficial effect to a buccal cavity of a mammal, for example, a human.
[0045] [00045] The methods involve bringing a plurality of surfaces of the oral cavity into contact with a liquid that is effective in providing the desired beneficial effect to the oral cavity. In these methods, the reciprocation of the liquid (s) on the plurality of surfaces of the oral cavity can be provided under effective conditions to provide the desired beneficial effect to the oral cavity. The contact of the plurality of surfaces to be touched by the liquid can be conducted substantially simultaneously. By "substantially simultaneous", it is understood that, although not all the pluralities of surfaces of the oral cavity to be touched are necessarily touched by the fluid at the same time, most of the surfaces to be touched are touched simultaneously, or in a short period of time.
[0046] [00046] The conditions for providing the desired beneficial effect on the oral cavity may vary depending on the particular environment, circumstances and the desired effect. The different variables are interdependent in that they create a specific velocity of the liquid. The speed requirement may be a function of the formulation, in some modalities. For example, with the change in viscosity, in additives, for example, abrasives, agents whose viscosity decreases under shear etc., and in the general flow properties of the formulation, the speed requirements of the jets can change to produce the same level of effectiveness . Factors that can be considered to provide the right conditions to obtain the particular beneficial effect sought include, but are not limited to, the speed and / or flow and / or pressure of the liquid stream, pulsation of the liquid, the spray geometry or spray pattern of the liquid, the temperature of the liquid and the frequency of the reciprocating cycle of the liquid.
[0047] [00047] The pressures of the liquid, that is, the pressure of the piping just before exiting through the jets, can be from about 3.45 kPa to about 206.8 kPa (about 0.5 psi to about 30 psi), or about 20.7 kPa to about 103.4 kPa, or about 34.5 (about 3 to about 15 psi, or about 5 psi). The liquid flow can be from about 15 ml / s to about 25 ml / s. It should be noted that the greater and higher the number of jets, the greater the flow required at a given pressure / speed. The pulse rate (linked to pulse length and release (mL / pulse) can be from about 0.5 Hz to about 50 Hz, or from about 5 Hz to about 25 Hz. The release duty cycle of the pulse can be from about 10% to 100%, or from about 40% to about 60%. It is observed that at 100% there is no pulse, but instead, there is a continuous flow of liquid. of pulse release (total volume in all jets / nozzles) can be from about 0.2 ml to about 120 ml, or from about 0.5 ml to about 15 ml. about 4 cm / s to about 400 cm / s, or about 20 cm / s to about 4.06 m / s (160 in / s). The emptying time can be about 10 % to 100%, or about 50% to 100%. It is observed that emptying is always on. The ratio between volumetric release and emptying can be from about 2: 1 to about 1:20, or from about 1: 1 to 1:10. Once having the benefit of this description, the skilled person will understand that and the various factors can be controlled and selected depending on the particular circumstances and the desired benefit sought.
[0048] [00048] The liquid (s) will include at least one ingredient, or agent, effective to provide the sought after beneficial effect, in an amount effective to provide the beneficial effect when placed in contact with the surfaces of the oral cavity . For example, the liquid may include, without limitation, an ingredient selected from the group consisting of a cleaning agent, an antimicrobial agent, a mineralizing agent, a desensitizing agent and a bleaching agent. In certain embodiments, more than one liquid can be used in a single session. For example, a cleaning solution can be applied to the oral cavity, followed by a second solution containing, for example, a bleaching agent or an antimicrobial agent. Solutions can also include a plurality of agents to realize more than one benefit with a single application. For example, the solution may include a cleaning agent and an agent to improve a harmful condition, as further discussed below. In addition, a single solution can be effective to provide more than one beneficial effect to the oral cavity. For example, the solution may include a single agent that cleans the oral cavity and acts as an antimicrobial agent, or that cleans the oral cavity and whitens teeth.
[0049] [00049] Liquids useful for improving the cosmetic appearance of the oral cavity may include a whitening agent to whiten teeth in the cavity. These bleaching agents may include, without limitation, hydrogen peroxide and carbamide peroxide, or other agents capable of generating hydrogen peroxide when applied to teeth. These agents are well known in the art related to whitening products for oral treatment, such as rinses, toothpaste and whitening strips. Other bleaching agents may include abrasives such as silica, sodium bicarbonate, alumina, apatites and bioglass.
[0050] [00050] It is noted that, although abrasives can be used to clean and / or whiten teeth, certain abrasives can also serve to improve teeth hypersensitivity caused by loss of enamel and exposure of tubules in teeth. For example, the particle size, for example, diameter, of certain materials, for example, bioglass, can be effective in blocking the exposed tubules, thus reducing the sensitivity of the teeth.
[0051] [00051] In some embodiments, the liquid may comprise an antimicrobial composition containing an alcohol that has 3 to 6 carbon atoms. The liquid may be an antimicrobial rinse composition, particularly one that has a low ethanol content or is substantially ethanol free, providing a high level of effectiveness in preventing plaque, gum disease and bad breath. The alcohols indicated having 3 to 6 carbon atoms are aliphatic alcohols. An aliphatic alcohol having 3 carbons, in particular, is 1-propanol.
[0052] [00052] In one embodiment, the liquid may comprise an antimicrobial composition comprising (a) an effective microbial amount of thymol and one or more other essential oils, (b) from about 0.01% to about 70.0% v / v, or about 0.1% to about 30% v / v or about 0.1% to about 10% v / v or about 0.2% to about 8% v / v an alcohol that has 3 to 6 carbon atoms and (c) a vehicle. The alcohol can be 1-propanol. The liquid carrier can be aqueous or non-aqueous, and can include thickening agents or gelling agents to provide a particular consistency to the compositions. Water and water / ethanol mixtures are the preferred vehicle.
[0053] [00053] Another embodiment of the liquid is an antimicrobial composition comprising (a) an effective antimicrobial amount of an antimicrobial agent, (b) from about 0.01% to about 70% v / v, or about 0.1 % to about 30% v / v, or about 0.2% to about 8% v / v, of propanol and (c) a vehicle. The antimicrobial composition of this modality has unexpectedly superior release system kinetics compared to the ethanolic systems of the prior art. Exemplary antimicrobial agents that can be used include, but are not limited to, essential oils, cetylpyridium chloride (CPC), chlorhexidine, hexetidine, chitosan, triclosan, domiphen bromide, stannous fluoride, soluble pyrophosphates, metal oxides including, but not limited to limiting to, zinc oxide, mint oil, sage oil, sanguine, dihydrate dihydrate, aloe vera, polyols, protease, lipase, amylases, and metal salts including, but not limited to, zinc citrate, and the like . A particularly preferred aspect of this modality is directed to an antimicrobial mouthwash, for example, a mouthwash having about 30% v / v or less, or about 10% v / v or less, or about 3% v / v or less, of 1-propanol.
[0054] [00054] Yet another embodiment of the liquid is an antimicrobial mouthwash composition with reduced ethanol comprising (a) an effective microbial amount of thymol and one or more other essential oils; (b) about 0.01 to about 30.0% v / v or about 0.1% to about 10% v / v or about 0.2% to about 8% v / v an alcohol that has 3 to 6 carbon atoms; (c) ethanol in an amount of about 25% v / v or less; (d) at least one surfactant; and (e) water. Preferably, the total concentration of ethanol and alcohol having 3 to 6 carbon atoms is not more than 30% v / v, or not more than 25% v / v, or not more than 22% v / v.
[0055] [00055] In yet another embodiment, the liquid is an antimicrobial mouthwash composition without ethanol that comprises (a) an effective microbial amount of thymol and one or more other essential oils; (b) about 0.01% to about 30.0% v / v or about 0.1% to about 10% v / v or about 0.2% to about 8% of an alcohol which has 3 to 6 carbon atoms; (c) at least one surfactant; and (d) water.
[0056] [00056] The alcohol having 3 to 6 carbon atoms is preferably selected from the group consisting of 1-propanol, 2-propanol, 1-butanol, 2-butanol, tert-butanol and corresponding diols. 1-Propanol and 2-propanol are preferred, with 1-propanol being the most preferred.
[0057] [00057] In addition to generally improving oral hygiene of the oral cavity by cleaning, for example, removing or interrupting the formation of plaque, food particles, biofilm etc., the inventions are useful for improving harmful conditions within the oral cavity and improving the cosmetic appearance of the oral cavity, for example, teeth whitening. Harmful conditions can include, but are not limited to, cavities, gingivitis, inflammation, symptoms associated with periodontal disease, halitosis, tooth sensitivity and fungal infection. The liquids themselves can be in various forms, as long as they have the flow characteristics suitable for use in the devices and methods of the present invention. For example, liquids can be selected from the group consisting of solutions, emulsions and dispersions. In certain embodiments, the liquid may comprise a particulate, for example, an abrasive, dispersed in a liquid phase, for example, an aqueous phase. In these cases, the abrasive would be dispersed substantially homogeneously in the aqueous phase in order to be applied to the surfaces of the oral cavity. In other embodiments, an oil-in-water or water-in-oil emulsion can be used. In this case, the liquid will comprise a discontinuous oil phase dispersed substantially homogeneously in a continuous aqueous phase, or a discontinuous water phase dispersed substantially homogeneous in a continuous oil phase, as the case may be. In still other embodiments, the liquid can be a solution in which the agent is dissolved in a vehicle, or in which the vehicle itself can be considered as the agent to provide the desired beneficial effect, for example, an alcohol or alcohol / alcohol mixture. water, generally having other agents dissolved in it.
[0058] [00058] Here are presented devices, for example, devices for oral treatment, for example, a dental cleaning device suitable for home use and adapted to direct liquid over a plurality of surfaces of a tooth and / or gingival area, as well as methods and systems that use these devices. In certain embodiments, the surfaces of the oral cavity to be touched are touched by the liquid substantially simultaneously. For use in the present invention, reference to the gingival area includes, without limitation, reference to the subgingival pocket. The suitable liquid can be directed over a plurality of tooth surfaces and / or gingival area substantially simultaneously in a reciprocal action under conditions effective to provide cleaning, and / or general improvement of the cosmetic appearance of the oral cavity and / or improvement of a harmful condition of the teeth and / or gingival area, thus providing improved oral hygiene in general of the teeth and / or gingival area. For example, one of these devices cleans the teeth and / or the gingival area and removes the plaque with the use of an appropriate cleaning fluid by reciprocating the liquid back and forth over the front and rear surfaces and interproximal areas of the teeth creating, thus, a cleaning cycle and reducing the amount of cleaning liquid used.
[0059] [00059] The devices that provide reciprocation of the liquid comprise a means to control the reciprocation of the liquid. The control means includes means for transporting the liquid to and from the device for directing the liquid over the plurality of surfaces of the oral cavity. In certain embodiments, the means for providing reciprocation of the liquid comprises a plurality of portals for receiving and releasing the liquid, a plurality of passages, or conduits, through which the liquid is transported and means for changing the direction of flow of the liquid to provide reciprocation of the liquid, as described in more detail later in this document. The control means can be controlled by a logic circuit and / or a mechanically controlled circuit.
[0060] [00060] In certain embodiments, devices for providing reciprocation may include means for securing or connecting the device to a reservoir to contain liquid. The reservoir can be removably attached to the device. In that case, the reservoir and the device may comprise means for securing each other. After the process is finished, the reservoir can be discarded and replaced with a different one, or it can be refilled and used again. In other embodiments, the reciprocating device will include a reservoir integrated with the device. In the embodiments in which the device can be attached to a base unit, as described in the present invention, the reservoir, either integrated into the device or removably attached to the device, can be refilled from a supply reservoir that is part of the base unit. When a base unit is used, the device and the base unit will comprise means for fixing each other.
[0061] [00061] The device will comprise a power supply to boost the means for reciprocating liquids. The power supply can be contained within the device, for example, in the device cable, for example, batteries, whether they are rechargeable or disposable. When a base unit is used, the base can include means to supply power to the device. In other embodiments, the base unit may include means for recharging the rechargeable batteries contained within the device.
[0062] [00062] The device may also include a timer to clean sections of the teeth, gums, or oral cavity. When the timer elapses, the device stops pumping as an indicator to move to the next section. The power is then reset by the user. This can minimize the possibility for the user to move the device outside the area being cleaned and / or treated during the operation of the device.
[0063] [00063] The means for providing reciprocating of liquids will include means for fixing the reciprocating means to a device for directing the liquid to the plurality of surfaces of the oral cavity, for example, a liquid applicator, according to the invention. In certain embodiments, the applicator offers substantially simultaneous contact of the plurality of surfaces of the oral cavity by the liquid. The attachment means can provide removable attachment of the applicator to the device. The fixing means can be in the form of a quick-disconnect structure. In such modalities, multiple users can use their own applicators with a single reciprocating medium. Devices for providing reciprocation, as described above, can be contained within a compartment that also contains other components of the device, in order to provide a suitable device for delivering liquid to the applicator, as described in the present invention and below.
[0064] [00064] The devices for directing liquid over the plurality of surfaces of the oral cavity according to the present invention, for example the liquid applicator, comprise a handle, a neck and a head. It is noted that the terms "device for directing liquid", "liquid applicator" and "device for liquid application" are used interchangeably in the present invention.
[0065] [00065] The liquid applicator cable includes first and second ports located at a proximal end of the cable to receive the liquid from the source, coming from a base reservoir unit, or the reciprocating medium. The ports can interface with the liquid's source path, for example, hoses, ducts or other suitable means to transport the liquid from the source of the liquid to the fluid applicator. The cable also includes first and second channels for transporting the liquid through the cable and to the neck and head portions of the liquid applicator. The first and second channels are connected to the first and second ports, respectively, at the proximal end of the cable and extend longitudinally through the cable to the applicator's neck.
[0066] [00066] The neck of the liquid applicator includes the first and second channels for transporting the fluid disposed inside and extends longitudinally to the head of the liquid applicator. The channels then terminate at a tubing feeder connecting the fluid channels with the respective fluid tubing located at the applicator head.
[0067] [00067] The head includes a cleaning component comprising a chamber to hold the liquid adjacent to the plurality of surfaces, that is, the liquid contact chamber (LCC). By "close", it is understood that the liquid is kept in contact with the surfaces. The LCC is defined by the space bounded by proximal and distal sealing membranes, first and second internal side walls that extend longitudinally between the first and second sealing membranes, and an internal base wall that extends horizontally between the first and second walls internal and longitudinal sides between the proximal and distal sealing membranes. The first and second internal side walls of the cleaning component each include a plurality of openings, or slits, through which the liquid is directed to come into contact with the plurality of surfaces of the oral cavity.
[0068] [00068] The head of the liquid applicator also includes a first pipe to contain a first portion of liquid and provide it to the LCC through the openings of the first inner side wall, a second pipe to contain a second portion of liquid and supply the same to the LCC through the openings of the second internal side wall, a first port for transporting the first portion of the liquid to and from the first pipe, and a second port for transporting the second portion of the liquid to and from the second pipe.
[0069] [00069] The cleaning component can be optimized for maximum effectiveness, as it is related to the size, shape, thickness, materials and volume created around the teeth / gum, nozzle design and placement, as it is related to the cavity mouth and teeth, together with the tubing and sealing of the gingival margin to provide comfort and minimize the pharyngeal reflex of the user. The combination of the above properties provides effective contact of the teeth and the gingival area by the liquid.
[0070] [00070] The cleaning component offers a controlled and isolated environment with known volume, that is, the LCC, to place the teeth and / or gingival area in contact with liquids and then remove used liquids, as well as debris, plaque etc. LCC, without exposing the entire oral cavity to liquid, debris, etc. This reduces the potential for fluid intake. The cleaning component also allows for an increase in flow rates and pressure of liquids without obstructing individual nozzles when significant flow rates are required to provide adequate cleaning, for example. The cleaning component also allows for reduced amounts of fluid and flow rates when necessary, since only the area within the LCC is being placed in contact with the liquid and not the entire oral cavity. The cleaning component also allows controlled release and duration of liquid contact over, through and around the teeth and gingival area, allowing increased concentrations of fluids in the area being placed in contact with the liquid, thereby providing control and release most effective of the liquid.
[0071] [00071] The number and location of the openings, also called in the present invention, cracks, jets or nozzles contained within the internal walls of the cleaning component, through which the liquid is directed will vary and can be determined based on the circumstances and in the environment of use, in the user in particular and in the beneficial effect being sought. The cross-sectional geometry of the openings can be circular, elliptical, trapezoidal, or any other geometry that provides effective contact of the surfaces of the oral cavity by the liquid. The location and number of openings can be designed to target jets of liquid in a variety of effective spray patterns to provide the desired beneficial effect. The opening diameters can be from about 0.1 to about 3 mm, or from about 0.2 mm to about 0.8 mm, or about 0.5 mm, to provide average cleaning and jet speed effective coverage and coverage.
[0072] [00072] The most favorable placement and direction / angles of the opening allow coverage of substantially all tooth surfaces in the oral cavity area to be contacted by the liquid, including, but not limited to, interdental, upper, lateral, posterior surfaces and the gingival pouch. In alternative embodiments, the openings may be of different sizes and different shapes to provide different cleaning, coverage and spray patterns, to adjust speeds, density and fan patterns (full cone, fan, partial, cone, jet), or due to formulation considerations. The cleaning component can be an elastomeric material such as ethylene-vinyl acetate (EVA), thermoplastic elastomer (TPE), or silicone, to allow the movement of the internal walls and provide a larger area of coverage of the jet with minimal mechanics, reducing needs volumetric flow to achieve optimum performance, while providing a more flexible and softer material to protect teeth and / or gums if direct contact is made with teeth and / or gums. A flexible membrane can also provide acceptable adjustments over a wide range of users, due to its ability to conform to teeth and / or gums, and act as a flexible gingival membrane to provide an efficient seal. Alternatively, the cleaning component can be made of a rigid or semi-rigid material, for example, but not limited to a thermoplastic.
[0073] [00073] In an alternative embodiment, the cleaning component can also include abrasive elements such as filaments, textures, polishing elements, additives (silica etc.), and other geometric elements that can be used for other cleaning and / or treatment needs , and to ensure a minimum distance between the teeth and the cleaning component for, but not limited to, treatment, cleaning and positioning. The cleaning component can be created using a variety of methods such as, but not limited to, machining, injection molding, blow molding, extrusion, compaction modeling, and / or vacuum forming. The material for the pipe would be a semi-rigid thermoplastic, which provides the necessary rigidity not to flatten or explode during the controlled flow of liquids, but to provide some flexibility when adjusting inside the user's mouth for insertion, sealing / position and removal of the cleaning component. To minimize manufacturing complexity, the number of components and the cost of tools, the double tubing is created when assembled with the liquid contact chamber (TCCL) tubing. The tubing could also be multicomponent to provide a softer external "tactile sensation" to the teeth / gums using a smaller durometer elastomeric material, for example, but not limited to a compatible thermoplastic elastomer (TPE). Piping could be created by a variety of methods, such as, but not limited to, machining, injection molding, blow molding, compacting modeling, or vacuum forming.
[0074] [00074] The devices of the invention also comprise a first port for transporting the liquid to and / or the first pipe and a second port for transporting the liquid to and from the second pipe, and means for providing an effective seal of the targeting means inside the oral cavity, that is, a gingival seal and / or the teeth. In certain embodiments, the first and second ports can serve to transport liquid to and from the first and second pipes and to attach the applicator to the means for supplying liquid to the applicator. In other embodiments, the targeting means may also include means for attaching the targeting means to the means for supplying liquid to the targeting means.
[0075] [00075] Figure 1 is a schematic drawing of an embodiment of a system using the devices, in accordance with the present invention. The Figure shows the system 200 with components that include: means for providing reciprocation 202 of the liquid in the oral cavity, means for directing the liquid over the plurality of surfaces of the oral cavity, in this case shown as a liquid applicator 100 and the reservoir for liquid supply 290. Means for providing reciprocating 202 of liquids may, in this embodiment, include the release / collection device 210, reciprocating flow controller 230, tubes 212, 216 and 292 for transporting liquid throughout the system, and valves for unidirectional liquid flow 214, 218 and 294. Tubes 232 and 234 provide transport of liquid from the reciprocating flow controller 230 to liquid applicator 100.
[0076] [00076] In some embodiments, the release / collection device 210 can be a piston pump. The liquid supply reservoir 290 can be made of glass, plastic or metal. The liquid supply reservoir 290 can be an integral part of system 200 and can be refillable. In some embodiments, the liquid supply reservoir 290 may be a replaceable liquid supply, such as a single or multiple use cartridge, separably connected to system 200.
[0077] [00077] In some embodiments, the liquid supply reservoir 290 and / or tubes 212 and 292 may include a heat source to preheat the liquid before it is directed to applicator 100 to be applied to the surfaces of the buccal cavity. The temperature must be kept within an effective range to provide efficiency and comfort to the user during use.
[0078] [00078] Applicator 100, discussed in detail later in this document, can be connected to reciprocating medium 202 separably via tubes 232 and 234 and additional fastening means (not shown). It could have one or two sides with easily cleaned internal filters to capture food particles. When positioned within the oral cavity, for example, on the teeth and gums, applicator 100 forms an effective fit or seal against the gums, and directs the liquid against the surfaces of the oral cavity, for example, the surfaces of the teeth.
[0079] [00079] The liquid in the liquid supply reservoir 210 flows through the tube 292 to the release / collection device 290. The flow of liquids through the tube 294 is controlled by a unidirectional flow valve 292. From the release / collection device 210, liquid flows through tube 212 to reciprocating flow controller 230. One-way flow valve 214 controls the flow of liquids through tube 212. Liquid flows from reciprocating flow controller 230 to applicator 100 through tube 232 or 234, depending on the flow direction setting of the reciprocating flow controller 230. Liquid flows from applicator 100 through tube 234 or 232 or back to reciprocating flow controller 230 and from reciprocating flow controller 230 to the release device / collects 210 through tube 216. One-way flow valve 218 controls the flow of liquids through tube 216.
[0080] [00080] The actions of the release / collection device 210 can be controlled by a logic circuit, which can include a program to start the reciprocation cycle, a program to execute the reciprocation cycle, that is, to make the liquid be reciprocated on the teeth, thus providing the beneficial effect to the oral cavity, for example, cleaning the teeth, a program to empty the applicator 100 at the end of the reciprocating cycle, and a self-cleaning cycle to clean the system between uses or pre-established or automatic cleaning times.
[0081] [00081] Although not shown, a front panel with a series of switches and indicator lights can also be incorporated into the 200 system. The switches can include, but are not limited to, turning on / off, filling the applicator 100, executing the reciprocation program, empty system 200 and clean system 200. Indicator or display lights include, but are not limited to, on, loading, running reciprocation program, system emptying, cleaning results or feedback, and self-cleaning cycle in operation. In the modalities in which the liquid is preheated before being directed to applicator 100, a display light can be used to indicate that the liquid is at the temperature suitable for use.
[0082] [00082] One method for using system 200 to clean teeth is as follows. In the first step, the user places the applicator 100 in the oral cavity around the teeth and gingival area to be cleaned. The release / collection device 210 is activated to start extracting the cleaning liquid from the liquid supply reservoir 290 through the tube 292 and the one-way valve 294. When the release / collection device 210 is sufficiently full, the release device / collection 210 is activated to start dispensing cleaning liquid to applicator 100 through pipe 212, one-way flow valve 214 of reciprocating flow controller 230 and pipe 232. Cleaning liquid will be prevented from flowing through the tubes 216 and 292 through one-way flow valves 218 and 294, respectively. The release / collection device 210 is activated to start extracting the cleaning liquid from applicator 100 through tube 234, then through reciprocating flow controller 230, then through tube 216 and one-way flow valve 218 The cleaning liquid will be prevented from flowing through the tube 214 through the one-way flow valve 212. If there is insufficient cleaning liquid to properly fill the release / collection device 210, additional cleaning liquid can be extracted from the reservoir for liquid supply 290 through tube 292 and one-way flow valve 294. The direction of liquid flow is then reversed. To reciprocate the cleaning liquid, steps 2 and 3 are repeated after the flow direction is reversed, generating a cleaning liquid cycle between the release / collection device 210 and applicator 100 using tubes 234 and 232, respectively. The reciprocating cycle described continues until the time required for cleaning is complete, or until the desired number of cycles is completed. It is noted that there may be a delay between the release of the fluid to the applicator 100 and the extraction of the fluid from the applicator 100 (in one or both directions), allowing a dwell time in cases in which the liquid has been allowed to come into contact. contact with teeth without flow.
[0083] [00083] Figure 2 is a schematic drawing of an alternative embodiment of a system using the devices according to the present invention. The Figure shows system 400 with components that include: means for providing reciprocation 402 of liquids in the oral cavity, reservoir for liquids 470, reservoir for supplying liquid 490, and means for directing the liquid over the plurality of surfaces of the oral cavity, in that instance shown as a liquid applicator 100. Means for providing reciprocation 402 may include release device 410, collection device 420, reciprocating flow controller 430, tubes 412, 422a, 422b, 472, 476 and 492, and valves with flow one-way solution 414, 424a, 424b, 474, 478 and 494. Tubes 432 and 434 provide transport of the liquid from the reciprocating flow controller 430 to the liquid applicator 100.
[0084] [00084] In the present embodiment, the release device 410 and the collection device 420 are housed together as a double-acting piston pump, with a common piston 415. The liquid supply reservoir 490 and the liquid reservoir 470 can be made of glass, plastic or metal. The 490 liquid supply reservoir can be an integral part of the 400 system and can be refillable. In some embodiments, the liquid supply reservoir 490 can be a replaceable liquid supply, separably connected to the 400 system.
[0085] [00085] In some embodiments, any of the reservoirs for liquid supply 490 reservoir for liquids 470, or tubes 412, 472 and 492, may include a heat source to preheat the cleaning solution before it is directed to applicator 100 to be applied to the teeth. The temperature must be kept within an effective range to provide comfort to the user during use.
[0086] [00086] Applicator 100 can be connected separably from reciprocating means 402 by means of tubes 432, 434 and other fixing means (not shown).
[0087] [00087] The liquid in the liquid supply reservoir 490 flows through the tube 492 to the liquid reservoir 470. The liquid in the reservoir 470 flows through the tube 472 to the release device 410. The flow of liquids through the tube 472 is controlled by a unidirectional flow valve 474. From the release device 410, liquid flows through tube 412 to the reciprocating flow controller 430. Unidirectional flow valve 414 controls the flow of liquids through tube 412. Liquid flows from the reciprocating flow controller 430 for liquid applicator 100 through tube 432 or tube 434, depending on the direction of flow. Liquid flows from the liquid applicator 100 through tube 434 or tube 432, again depending on the flow direction, back to the reciprocating flow controller 430, and from the reciprocating flow controller 430 to the collection device 420, through the tubes 422a and 422b. The one-way flow valves 424a and 424b control the flow of liquids through the tubes. Finally, liquid flows from the collecting device 420 to the liquid reservoir 470 through tubes 476a and 476b. The unidirectional flow valves 478a and 478b control the flow of liquids through the tubes.
[0088] [00088] The actions of the release device 410 and the collection device 420 can be controlled by a logic circuit, which can include a program to start the reciprocation cycle, a program to execute the reciprocation cycle, that is, to do with the solution to be reciprocated on the plurality of surfaces of the oral cavity, thus providing the beneficial effect, a program to empty the liquid applicator 100 at the end of the cycle, and a self-cleaning cycle to clean the system between uses or pre-established or automatic cleaning times.
[0089] [00089] One method for using the 400 system to clean teeth is as follows. Before use, the cleaning liquid in the liquid supply reservoir 490 flows through the tube 492 and the one-way valve 494 to the cleaning liquid reservoir 470. In some embodiments, the liquid supply reservoir 490 is now disconnected from the system 400.
[0090] [00090] In the first step, the user positions the liquid applicator 100 in the oral cavity around the teeth and oral cavity to be touched. The cleaning process is as follows:
[0091] [00091] Piston 415 is activated to start extracting the cleaning liquid to the release device 410 from the cleaning liquid reservoir 470 through the tube 472 and the one-way valve 474. To do this, the piston 415 rotates from the right to the left ("R" to "L" in Figure 3). When the release device 410 is sufficiently full, the release device 410 is activated to begin dispensing cleaning liquid to applicator 100 through tube 412, one-way flow valve 414, reciprocating flow controller 430 and the tube 432. For this, piston 415 rotates from left to right ("L" to "R" in Figure 3). The "L" to "R" movement of piston 415 causes the collection device 420 to start extracting cleaning liquid from applicator 100 through tube 434, reciprocating flow controller 430 from tube 422a, and the unidirectional flow valve. 424a. The cleaning liquid will be prevented from flowing through tubes 472 and 422a, through the unidirectional flow valves 474 and 424b. Any excess cleaning liquid in the collection device 420 will begin dispensing to the cleaning liquid reservoir 470 through the tube 476b and the one-way valve 478b. The cleaning liquid will be prevented from flowing through the pipe 422b through the unidirectional flow valve 424b. For the cycle cleaning solution, the release steps are repeated, generating a cycle of cleaning liquid between the cleaning solution reservoir 470 and the liquid applicator 100. The process continues until the time required for cleaning is complete, or until the desired number of cycles is completed.
[0092] [00092] Each modality described in Figures 1 and 2 includes the optional reciprocating flow controller (230 and 430 in Figure 1 and Figure 2, respectively). A perspective view and an exploded view of an embodiment of a reciprocating flow controller, according to the present invention, are shown in Figure 3a and Figure 3b, respectively. The figures show the reciprocating flow controller 710 with cover 720, flow diverter disk 730 and base 740. Cover 720 has cover ports 722 and 724. Base 740 has base ports 742 and 744. The flow diverter disc 730 is disposed between the cap 720 and the base 740 and has the panel 735 for diverting the flow of liquids and the position adjuster 732 in the form of a gear.
[0093] [00093] Figure 3c is a top view of the reciprocating flow controller 710 in its first position. In this position, the inlet liquid, like the liquid in tube 212 of Figure 1, enters the reciprocating flow controller 710 through the base port 742. The liquid exits the reciprocating flow controller 710 through the cover door 722, like the liquid in tube 232 of Figure 1 The return liquid, like the liquid in tube 234 of Figure 1, re-enters the reciprocating flow controller 710 through the cover door 724. The liquid exits again from the reciprocating flow controller 710 through the port base 744, like the liquid in the tube 216 of Figure 1.
[0094] [00094] Figure 3d is a top view of the reciprocating flow controller 710 in its second position. In this position, the inlet liquid, like the liquid in tube 212 of Figure 1, enters the reciprocating flow controller 710 through the base port 742. The liquid exits the reciprocating flow controller 710 through the cover door 724, like the liquid in tube 234 of Figure 1. The return liquid, like the liquid in tube 232 of Figure 1, re-enters reciprocating flow controller 710 through cover door 722. Liquid exits reciprocating flow controller 710 through port base 744, like the liquid in the tube 216 of Figure 1.
[0095] [00095] The liquid reciprocation in the liquid applicator 100 of Figure 1 is obtained by changing the reciprocating flow controller 710 from its first position to its second position. It has been found that the width of the panel 735 in relation to the diameters of the cover doors 722 and 724 of the base doors 742 and 744 is of critical importance for the performance of the reciprocating flow controller 710. If the width of the panel 735 is equal to or larger than any of the diameters, then one or more of the cover ports 722 and 724 or base ports 742 and 744 may be blocked, or isolated, during part of the reciprocation, resulting in suboptimal performance or device failure. A channel can be located on panel 735 to avoid this condition.
[0096] [00096] The oral hygiene system can be comprised of several components including, but not limited to, a base station, a unit for containing means for providing reciprocation of the liquid around the plurality of surfaces within the oral cavity, and the device to direct the liquid over the plurality of surfaces of the oral cavity to be treated / cleaned, that is, the liquid applicator. The system is suitable for home use and is adapted to direct the liquid over a plurality of tooth surfaces. The device cleans teeth and removes plaque using a cleaning solution that can be reciprocated back and forth creating a cleaning cycle and reducing the amount of cleaning solution used. The base station can charge a rechargeable battery, contain liquid reservoirs, house diagnostic components, provide feedback to the user, and potentially clean the applicator.
[0097] [00097] The means for providing reciprocation will have a pump equipped with an engine that will supply liquid from the reservoir to the liquid applicator. The flow direction can be reciprocated with liquid control valves by a specialized pump (reversing its direction, etc.), reversible check valves, or other similar means. The cycle time and flow speed for each stage of the cycle will be variable and, in some modalities, will be customized for each individual user.
[0098] [00098] The third major component of the device is the device for directing liquid to the plurality of surfaces in the oral cavity to be cleaned / treated, that is, the liquid applicator. Figures 4 to 11 show a first embodiment of a liquid delivery device. Figure 4 is an upper right perspective view of a first embodiment of the liquid applicator device 100, according to the present invention. Figure 5 is a top view of the liquid applicator 100 of Figure 4, while Figure 6 is a side view of the liquid applicator 100 of Figure 4. The Figures show the applicator 100 with handle 120, neck 130, and head 140. The first port 122 and the second port 124 for receiving liquid from the liquid reservoir are located at the proximal end 121 of the cable 120, and connected to the first and second channels (not shown) originating at the proximal end 121. The cleaning component 150 is arranged in front of the head 140.
[0099] [00099] Figure 7 is a side view of the neck 130 and the head 140 of the liquid applicator 100 of Figure 4. The figure shows the cleaning component 150 disposed in front of the head 140. The sealing membrane in a proximal position 152 and the sealing membrane in distal position 154 is located at the ends of the cleaning component 150. Figure 8 is a horizontal sectional view of Figure 7 along the plane 8--8. The Figure shows the first fluid channel 142 and the second fluid channel 144 arranged in the neck 130 and the head 140. The first fluid channel 142 ends at the first feeder of piping 146, which connects the first fluid channel 142 to a first fluid tubing (not shown) in cleaning component 150. The second fluid channel 144 ends at the second feeder of tubing 148, which connects the second fluid channel 144 to a second fluid tubing (not shown) in cleaning component 150 .
[0100] [000100] Figures 9 to 11 are views of the cleaning component 150. Figure 9 is a top view of the cleaning component 150, including the sealing membrane in a proximal position 152, the sealing membrane in a distal position 154, the elements cleaning 155, the first side wall 156a, the second side wall 156b, and the inner base wall 158. Although the Figures show the cleaning elements 155 located on the first side wall 156a, on the second side wall 156b, and on the internal base 158, the cleaning elements 155 can be located on only one side wall (156a or 156b) or only on the internal base wall 158, or in any combination in other embodiments. In addition, the shape, size, number and diagrams of cleaning elements 155 can be optimized for optimal cleaning.
[0101] [000101] Figure 10 is a vertical sectional view of Figure 9 along the 10—10 plane, and Figure 11 is a vertical sectional view of Figure 9 along the 11-11 plane. The Figures show the first pipe feeder 146 connected to the first fluid pipe 172, and the second pipe feeder 148 connected to the second fluid pipe 174. The first fluid pipe 172 has first side nozzles 176a, which pass through the first wall side 156a, and first bottom nozzles 178a, which pass through the base of the inner wall 158. The second fluid tubing 174 has second side nozzles 176b, which pass through the second side wall 156b, and second bottom nozzles 178b, which pass through through the base of the inner wall 158. The liquid contact chamber (LCC) 160 is defined by the first side wall 156a, second side wall 156b, sealing membrane in a proximal position 152, sealing membrane in a distal position 154, and wall internal base 158.
[0102] [000102] It is to be understood that the configuration of the first side nozzles 176a, second side nozzles 176b, first bottom nozzles 178a, and second bottom nozzles 178b in Figures 4 to 11 are only one embodiment of the nozzle configuration. The configuration of the nozzles, as well as the geometry of the nozzle openings, may change.
[0103] [000103] Proximal sealing membrane 152 and distal sealing membrane 154 provide a flexible and universal sealing mechanism to minimize leakage within the oral cavity, while redirecting flow to and around teeth, to increase the treatment / cleaning area to reach places of difficult access (LDDA). The membrane can cause an elastic function across the longitudinal axis of the duct to be formed around the teeth and gums.
[0104] [000104] The base of the internal wall 158 provides the necessary flexibility for the fitting or effective sealing inside the oral cavity and allows the redirection and flow of fluids towards the surfaces of the teeth and / or gums. The base of the inner wall 158 can be a flexible membrane to provide an efficient seal.
[0105] [000105] In one operation, the liquid enters the first fluid channel 142 through the first port 122 under pressure and then passes through the first fluid tubing 172 and enters the LCC 160 through the first side nozzles 176a and of the first bottom nozzles 178a. A vacuum is produced in the second port 124 to draw the liquid through the second side nozzles 176b and the second bottom nozzles 178b, in the second fluid pipe 174, through the second fluid channel 144 and finally into the second port 124. In this mode, the jets of liquid are first directed from the first pipe to the first surfaces of the teeth and / or gingival area from one side of the LCC 160, directed through, between, and around the surfaces of the teeth and / or gingival area a from the other side of LCC 160 and into the second pipe to provide cleaning or treatment of the controlled interdental surface, gum line, and / or gingival area. Then, the flow in the pipes is reversed. The cleaning liquid enters the second fluid channel 144 through the second port 124 under pressure and then passes through the second fluid tubing 174 and enters the LCC 160 through the second side nozzles 176b and second bottom nozzles 178b. A vacuum is produced in the first port 122 to draw the liquid through the first side nozzles 176a and the first bottom nozzles 178a, into the first fluid line 172, through the first fluid channel 142 and finally into the first port 122 In the second portion of this modality, jets of liquid are directed from the second pipe to the second surfaces of the teeth and / or gingival area, and directed through, between, and around the surfaces of the teeth and / or gingival area. The alternation of pressure / vacuum over numerous cycles creates a turbulent, repeatable and reversible flow to provide reciprocation of liquid over the plurality of surfaces of the oral cavity to bring the surfaces of the oral cavity into contact with the liquid substantially simultaneously, thus providing , the desired beneficial effect.
[0106] [000106] In another embodiment, it may be preferable to supply the liquid through one or both pipes simultaneously, filling the LCC 160, submerging the teeth and gums for a period of time and then emptying the LCC 160 after a period of defined time to one or both pipes. Here, the cleaning or treatment liquid simultaneously enters the first port 122 and the second port 124, simultaneously passes through the first fluid channel 142, the second fluid channel 144, the first pipe feeder 146, the second pipe feeder 148 , the first fluid tubing 172, and the second fluid tubing 174 under pressure, and then the LCC 160 enters simultaneously through the first side nozzles 176a, second side nozzles 176b, first bottom nozzles 178a, and second nozzles background 178b. To empty the LCC 160, a vacuum is simultaneously drawn up to the first port 122 and the second port 124. The cleaning or treatment liquid is drawn through the first side nozzles 176a and the first bottom nozzles 178a, inside the first fluid 172, and through the second side nozzles 176b and second bottom nozzles 178b, inside the second fluid pipe 174.
[0107] [000107] It is also possible to release different liquid compositions for the first fluid tubing 172 and the second fluid tubing 174. The different liquid compositions could then be combined in LCC 160 for effective cleaning or optimized treatment effects.
[0108] [000108] Although the embodiment of Figures 4 to 11 shows an individual cleaning component 150 in the head 140, it is to be understood that a second cleaning component that is similar to the cleaning component 150 can be arranged on the opposite front of the head 140. The second cleaning component would provide substantially simultaneous contact with a plurality of surfaces of the upper and lower sections of the oral cavity.
[0109] [000109] Figures 12 and 13 show a second embodiment of a liquid delivery device of the present invention. Figure 12 is a top and rear view of the neck 1130 and head 1140 of a liquid delivery device according to the present invention. The figure shows the first fluid channel 1142 and the second fluid channel 1144 disposed in the neck 1130. The cleaning component 1150 is disposed in front of the head 1140.
[0110] [000110] Figure 13 is a vertical sectional view of Figure 12 along the 13--13 plane. The figures show the first fluid channel 1142 connected to the first pipe feeder 1146, which is connected to the first fluid pipe 1162 in the cleaning component 1150. The first pipe feeder 1146 feeds the first liquid ducts 1156a, 1156b, 1156c. The figures also show the first nozzles 1166 in the first liquid duct 1156a, 1156b, 1156c. Although not shown in the figures, the second fluid channel 1144 connected to the second tubing feeder 1148, which is connected to the second fluid tubing 1164 in cleaning component 1150. The second tubing feeder 1148 feeds the second liquid duct 1157a, 1157b, 1157c and the second nozzles 1168 in the first liquid ducts 1157a, 1157b, 1157c.
[0111] [000111] It is to be understood that the layout of the first nozzles 1166 and the layout of the second nozzles 1168 are only one mode of configuration of the nozzle. The layout of the nozzles, as well as the geometry of the nozzle openings, can change.
[0112] [000112] Figures 12 and 13 show the cleaning component 1150 with six liquid ducts (1156a, 1156b, 1156c, 1157a, 1157b, and 1157c). In other embodiments, the cleaning component 1150 can be formed with two, three, four, five, seven, eight, nine, ten, or even more liquid ducts.
[0113] [000113] The multi-duct design provides bidirectional or exclusive ducts for flow and emptying that are self-reinforcing and therefore do not flatten under vacuum or break under pressure during use, increasing structural integrity, while reducing the cleaning component size 1150 for user comfort during insertion, use, and removal. This reduced size also serves to provide an intensified effective seal of the applicator in the oral cavity.
[0114] [000114] The multiple ducts (1156a, 1156b, 1156c, 1157a, 1157b, 1157c) as connected above form duct hinge sections. This can result in the design of several ducts that provide conformation in the X, Y and Z directions, due to the flexibility of the duct hinge sections between each duct. This design allows for effective and feasible tooth conformation and gingival topography for a variety of different users, providing effective gum sealing without irritating it and allowing dynamic positioning of the liquid cleaning jets around each tooth to achieve proximal and interdental cleaning. The multiple ducts are also attached to the first fluid pipe 1162 and the second fluid pipe 1164. This creates a secondary flexible joint that provides two additional degrees of movement to adjust to the different bite architectures that can be found.
[0115] [000115] Proximal sealing membrane 1152 and distal sealing membrane 1154 provide a flexible and universal sealing mechanism to minimize leakage within the oral cavity, while redirecting flow to and around teeth, to increase the treatment / cleaning area to reach places of difficult access (LDDA). The membrane can cause an elastic function across the longitudinal axis of the duct to be formed around the teeth and gums.
[0116] [000116] The ducts 1156a, 1156b, 1156c, 1157a, 1157b and 1157c, provide the necessary flexibility to fit or seal effectively within the oral cavity and allow the redirection and flow of fluids towards the surfaces of the teeth and / or gums.
[0117] [000117] In a cleaning operation mode, the cleaning liquid is pumped through the fluid channel 1142 and enters the first fluid pipe 1162 through the first feeder of the 1146 pipe. The liquid enters the first ducts of liquid 1156a, 1156b, and 1156c from the first fluid line 1162. The cleaning fluid then enters the LCC 1160 through the first nozzles 1166. A vacuum is produced at the second feeder in line 1148 (not shown) to pull the cleaning liquid through the second nozzles 1168 (not shown), for the second liquid duct 1157a, 1157b, and 1157c. The liquid enters the second fluid tubing 1164, then flows through the second tubing feeder 1148, and finally into the second fluid channel 1144.
[0118] [000118] In this embodiment, jets of cleaning liquid are first directed from the first 1162 fluid tubing to the first tooth surfaces and / or gingival area on one side of the LCC 1160 and directed through, between, and around the surfaces from the teeth and / or gingival area on the other side of the LCC into the second 1164 fluid tubing to provide controlled cleaning or treatment of the interdental area, gum line, surface and / or gingival area.
[0119] [000119] Then, the flow in the pipes is reversed. The cleaning liquid is pumped through the second fluid channel 1144, the second fluid tubing 1164 through the second feeder of tubing 1148. The liquid enters the second liquid duct 1157a, 1157b, and 1157c from the second fluid tubing 1164. The cleaning liquid then enters the LCC 1160 through the second nozzles 1168. A vacuum is produced in the first feeder of the 1146 pipe to pull the cleaning liquid through the first nozzles 1166, into the first liquid ducts 1156a, 1156b, and 1156c. The liquid enters the first fluid line 1162, then flows through the first feeder of line 1146, and finally into the first fluid channel 1142.
[0120] [000120] In the second portion of this modality, jets of cleaning liquid are directed to the second surfaces of the teeth and / or gingival area, and directed through, between, and around the surfaces of the teeth and / or gingival area. The alternation of pressure / vacuum for innumerable cycles creates a turbulent, repeatable and reversible flow to provide reciprocation of liquid over the plurality of surfaces of the oral cavity to bring the surfaces of the oral cavity into contact with the liquid substantially simultaneously, thus providing , the desired beneficial effect.
[0121] [000121] In another embodiment, it may be preferable to apply the liquid through one or both pipes simultaneously, fill the LCC 1160, submerge the teeth for a period of time, and then empty the LCC 1160 after a period of time established by one or both pipes. Here, the cleaning or treatment liquid is simultaneously pumped through the first fluid channel 1142 inside the first fluid pipe 1162 through the first feeder in the pipe 1146, and through the second fluid channel 1144 inside the second fluid pipe 1164 through the second feeder of pipe 1148. The liquid then enters the first liquid ducts 1156a, 1156b, and 1156c simultaneously from the first fluid pipe 1162, and the second liquid duct 1157a, 1157b, and 1157c from the second fluid pipe 1164 The cleaning liquid then enters the LCC 1160 simultaneously through the first nozzles 1166 and the second nozzles 1168. To empty the LCC 1160, a vacuum is simultaneously drawn into the first feeder of pipeline 1146 through the first fluid channel 1142, and the second pipe feeder 1148 through the second fluid channel 1144. The cleaning or treatment liquid is simultaneously drawn through the first the nozzles 1166 and the second nozzles 1168, into the first pipe feeder 1146 and the second pipe feeder 1148.
[0122] [000122] It is also possible to release different liquid compositions for the first 1146 pipe feeder and the second 1148 pipe feeder. The different liquid compositions would then combine in LCC 1160 for cleaning efficiency or optimized treatment effects. In the dual tubing design, it may be preferable to supply each tubing from a separate liquid supply reservoir, as in a double-acting piston pump configuration, where a supply line connects to supply the first 1146 tubing feeder. and the other piston feed line supplies and removes liquid from the second feeder of pipe 1148, for example, when one pipe is being supplied with liquid, the second pipe is removing liquid, and vice versa.
[0123] [000123] In other embodiments, valves can be placed at the inlets for the first liquid duct 1156a, 1156b, and 1156c or at the inlet for the second liquid duct 1157a, 1157b, and 1157c to provide enhanced function by allowing the ducts to engage at different times (at different points in the cleaning / treatment cycle) at pulsed intervals. As an example, in one modality, not all pipelines are involved with the liquid pumping / emptying function. Here, the first liquid duct 1156a and the second liquid duct 1157a, which primarily involve the gums, are only involved in the function of emptying the liquid. This helps to prevent leakage of liquid into the oral cavity. The valves also provide variable flow, allowing reduced resistance to the liquid emptying function or allowing an increase in pumping and, therefore, in the speed of the liquid during the release of the liquid.
[0124] [000124] In still other embodiments, the first internal nozzles 1166 or the second nozzles 1168 may have integrated one-way valves, such as duckbill valves or conical valves to allow flow in only one direction from those of the specific nozzles. This can be effective to increase the vacuum in relation to the pressure / release on the LCC 1160.
[0125] [000125] The manufacture of the design of several ducts for the cleaning component 1150 m using existing manufacturing and assembly processes available as extrusion, injection, vacuum, blow, or compaction modeling. Other feasible techniques include techniques for creating rapid prototypes such as three-dimensional printing and other additive techniques, as well as subtractive techniques.
[0126] [000126] One manufacturing method is to create individual component housings through vacuum forming. Low cost methods allow vacuum formation of very thin wall structures. The component geometry is designed to provide the fitting characteristics and structural geometry to allow the reduction of the size of the cleaning component 1150. When assembled, the manufactured components form the necessary flow structures and pipes (bidirectional and / or dedicated pipes) for provide the performance characteristics necessary for the treatment / cleaning of teeth.
[0127] [000127] The materials for the ducts can vary from materials with a shorter durometer (25 shore A) to more rigid materials (90 shore A), preferably having between 30 and 70 shore A.
[0128] [000128] Materials can be silicone, thermoplastic elastomer (TPE), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), ethylene vinyl acetate (EVA), polyurethane (PU), or multi-components (combination of materials and hardness content) to achieve the desired design and performance attributes.
[0129] [000129] The first nozzles 1166 and the second nozzles 1168 can be produced through a secondary operation such as drilling or punching, or formed during molding. Alternatively, the first nozzles 1166 and the second nozzles 1168 can be inserted into the cleaning component 1150 to provide better use and / or different performance characteristics of the jet and can be combined with friction cleaning elements or other components to improve the effect of the jet. cleaning and / or treatment.
[0130] [000130] Although the embodiment of Figures 12 and 13 shows an individual cleaning component 1150 on the head 1140, it is to be understood that a second cleaning component that is similar to the cleaning component 1150 can be arranged on the opposite front of the head 1140. The second cleaning component will provide substantially simultaneous contact with a plurality of surfaces of the upper and lower sections of the oral cavity.
[0131] [000131] Figures 14 to 20 show a third embodiment of the device of the application, according to the present invention. Figure 14 is a side view of the neck 2130 and head 2140 of the device. The figure shows the cleaning component 2150 arranged in front of the head 2140. The figures show the cleaning component 2150 including the sealing membrane in a proximal position 2152, the sealing membrane in a distal position 2154, the first side wall 2156a, the second side wall 2156b, and the inner base wall 2158. Figure 15 is a horizontal sectional view of Figure 14 along the plane 15--15. The figure shows the release channel 2142 and the drainage channel 2144 arranged on the neck 2130 and the head 2140. The feeder of the release pipe 2146 connects the release channel 2142 of the release pipe 2162 on the cleaning component 2150. The feeder of the emptying pipe 2148 connects emptying channel 2144 to emptying pipe 2164 on cleaning component 2150. Figure 16 is a horizontal sectional view of Figure 14 along the plane 16--16. The figure shows the release pipe feeder 2146 connected to the release pipe 2162, and the drain pipe feeder 2148 connected to the drain pipe 2162.
[0132] [000132] Figures 17 to 20 are views of the cleaning component 2150. Figure 17 is a top view of the cleaning component 2150, including the sealing membrane in a proximal position 2152, the sealing membrane in a distal position 2154, the elements cleaning tool 2155, the first side wall 2156a, the second side wall 2156b, and the inner base wall 2158. Although the figures show the cleaning elements 2155 located on the first side wall 2156a, on the second side wall 2156b, and on the internal base 2158, cleaning elements 2155 can be located on only one wall (2156a for example) or in any combination of the side walls (2156a and 2156b) and the internal base wall 2158, in other embodiments. In addition, the shape, size, number and diagrams of cleaning elements 155 can be optimized for optimal cleaning.
[0133] [000133] Figure 18 is a vertical sectional view of Figure 17 along the plane 18--18. The figure shows the liquid contact chamber (LCC) 2160, defined by the sealing membrane in the proximal position 2152, the sealing membrane in the distal position 2154, the first side wall 2156a, the second side wall 2156b, and the internal base wall 2158 The figure also shows that the release channel 2142 connects to the release pipe feeder 2146, which connects to the release pipe 2162. Although not shown, the drain channel 2144 connects to the drain pipe feeder 2148, which connects to the pipe emptying 2164. The fluid leaves the release piping 2162 through the release nozzles 2168a. The fluid enters the drain pipe 2164 through the drain nozzles 2168b.
[0134] [000134] Figure 19 is an end view of cleaning component 2150. Figure 20 is a vertical sectional view of Figure 19 along the plane 20--20. The figures show the release channel 2142 connected to the feeders of the release line 2146, which are connected to the release line 2162 on the cleaning component 2150. The release line 2162 feeds the release nozzles 2168a. The drain channel 2144 is connected to the drain pipe feeders 2148, which are connected to the drain pipe 2164 on the cleaning component 2150. The drain pipe 2164 carries the fluid from the drain nozzles 2168b.
[0135] [000135] Figure 20 shows the release nozzles 2168a located in the central region of the cleaning component 2150, while the emptying nozzles 2168b are located peripherally to the release nozzles 2168a. This nozzle layout is expected to result in a consistent flow of cleaning fluid through the LCC 2160. It is to be understood that the 2168b release nozzle layout and the 2168a nozzle layout are just one mode of nozzle configuration. The layout of the nozzles, as well as the geometry of the nozzle openings, may change.
[0136] [000136] The sealing membrane in the proximal position 2152 and the sealing membrane in the distal position 2154 provide a flexible and universal sealing mechanism to minimize leakage within the oral cavity, while redirecting flow to and around the teeth, to increase the treatment / cleaning area to reach places of difficult access (LDDA). The membrane can cause an elastic function across the longitudinal axis of the duct to be formed around the teeth and gums.
[0137] [000137] The base of the internal wall 2158 provides the necessary flexibility for the effective fitting or sealing inside the oral cavity and allows the redirection and flow of fluids towards the surfaces of the teeth and / or gums.
[0138] [000138] In a cleaning operation mode, the cleaning liquid is pumped through the release channel 2142 and enters the release pipe 2162 through the feeder of the release pipe 2146. The cleaning liquid then enters the LCC 2160 through of the first release nozzles 2168a. A vacuum is produced inside the emptying pipe feeder 2148 to draw the cleaning liquid through the emptying nozzles 2168b, into emptying pipe 2164, then flows to the emptying pipe feeder 2148, and finally inside the channel emptying system 2144.
[0139] [000139] In this modality, the jets of cleaning liquid are simultaneously directed from the 2162 release pipe to both tooth surfaces and / or gingival area at LCC 2160 to provide controlled cleaning or treatment of the gum line, surface and / or gingival area.
[0140] [000140] In another embodiment, it may be preferable to release the liquid through one or both pipes simultaneously, fill the LCC 2160, submerge the teeth for a period of time, and then empty the LCC 2160 after a period of time established by one or both pipes. Here, the cleaning or treatment liquid is simultaneously pumped through the release channel 2142 and the drain channel 2144. The liquid will enter the LCC 2160 simultaneously through the release nozzles 1268a and the drain nozzles 1268b. To empty the LCC 2160, a vacuum is simultaneously drawn into the release channel 2142 and the empty channel 2144. The cleaning or treatment liquid is simultaneously drawn through the release nozzles 1268a and the empty nozzles 1268b.
[0141] [000141] Although the embodiment of Figures 14 to 20 show an individual cleaning component 2150 on the head 2140, it is to be understood that a second cleaning component that is similar to the cleaning component 2150 can be arranged on the opposite front of the head 2140. The second cleaning component would provide substantially simultaneous contact with a plurality of surfaces of the upper and lower sections of the oral cavity.
[0142] [000142] Figures 21 to 27 show a fourth embodiment of a device of the application, according to the present invention. Figure 21 is an anterior perspective view of the right side of the neck and head of this modality. The Figure shows the neck 2530 and head 2540 of the device. The cleaning component 2550 is arranged in front of the head 2540. The cleaning component 2550 is comprised of sealing membranes 2552 at the proximal and distal ends of the cleaning component 2550, the side wall 2556a, the second side wall 2556b, and the wall base 2558. Cleaning elements 2555 are arranged on the first side wall 2556a, on the second side wall 2556b, and on the base wall 2558. The spray nozzles 2568 are arranged at the distal end of numerous cleaning elements 2555 located on the first side wall 2556a and the second side wall 2556b of the cleaning component 2550. It is important to note that in other embodiments the spray nozzles 2568 can be arranged over any one of the first side wall 2556a, the second side wall 2556b, the base wall 2558, or at the distal end of some or all of the cleaning elements 2555 located on any or all of the walls of the cleaning component 2550 The figure also shows the liquid contact chamber (LCC) 2560, defined by sealing membranes 2552, first side wall 2556a, second side wall 2556b, and base wall 2558.
[0143] [000143] Figures 22 and 23 are exploded views of the device of Figure 21. Figure 22 is an exploded front view on the right side, while Figure 23 is an exploded bottom view on the left side. Each figure shows the neck 2530, the head 2540, and the cleaning component 2550 of the device. Figure 22 shows tubing feeders 2546 and 2548, as well as the pivot hole of the head 2545 on the top surface of the head 2540. Figure 23 shows the pivot hole of the head 2545 on the bottom surface of the head 2540, as well as slits inlet pipe 2551 and 2557, hinge hole 2553 and rotation groove 2554 on the bottom surface of cleaning component 2550. Pipe feeders 2546 and 2548 are aligned with the pipe inlet slots 2551 and 2557, in order to create paths for the flow of fluids and the flow of emptying, from the first channel 2542 and the second channel 2544. As the cleaning component 2550 rotates around the articulation holes 2545 and 2553, pipe feeders 2546 and 2548 change the alignment with the 2551 and 2557 pipe inlet slits. Consequently, the cleaning component 2250 can articulate, that is, it is rotatable, around the horizontal and longitudinal axis of the 2540 head. Although not shown, a gasket can be placed in the 2554 rotation groove to prevent leakage, as cleaning component 2550 rotates around the top surface of the 2540 head. A pin that is also not shown in the figures is arranged in the articulation holes 2545 and 2553. This allows the rotation of the cleaning component 2550 on the top surface of the head 2540.
[0144] [000144] Figure 24 is a side view of the neck 2530 and the head 2540 of the device of Figure 21. The figure shows the cleaning component 2550 disposed in front of the head 2540. Figure 25 is a horizontal sectional view of Figure 24 along the 25--25 plane. The figure shows the first fluid channel 2542 and the second fluid channel 2544 arranged on the neck 2530 and the head 2540. The first feeder 2546 and the second feeder 2548 connect the first channel 2542 and the second channel 2544, respectively , to the first pipe 2562 or second pipe 2564 in the cleaning component 2550. Figure 26 is a horizontal sectional view of Figure 24 along plane 26--26. The figure shows the first pipe 2562 and the second pipe 2564.
[0145] [000145] Figure 27 is a vertical sectional view of Figure 21 along the plane 27 - 27. The Figure shows the first pipe 2562 of the cleaning component 2550. The spray nozzles 2568 are arranged on the first side wall 2556a of the component. cleaning agent 2550.
[0146] [000146] In a cleaning operation mode, the cleaning liquid is pumped through the first channel 2542 and enters the first pipe 2562 through the first feeder of pipe 2546. The cleaning liquid then enters the LCC 2560 through the spray nozzles 2568 located at the distal end of the cleaning elements 2555 arranged on the first side wall 2556a. A vacuum is drawn on the second feeder of pipe 2548 to draw the cleaning liquid through the emptying nozzles 2168 located at the distal end of the cleaning elements 2555, disposed on the second side wall 2556b inside the emptying pipe 2564. The fluid then flows through the second feeder of pipe 2548, and finally into the second channel 2544.
[0147] [000147] A modality of a base unit used with devices, according to the present invention, is shown in Figure 28. Figure 28 is a sectional view of the device 3000, showing the spatial relationships between the components in the pumping section , in the emptying section, and in the pumping and actuation sections. The volume of the cylinder 3412 is the volume of the sleeve of the vacuum cylinder 3410 not occupied by the components of the pumping section, the emptying section, and the pumping and actuation sections, and serves as a reservoir for liquids in the mode shown. The general operation of the 3000 device is as follows:
[0148] [000148] Device 3000 is sufficiently filled with cleaning liquid. The liquid is initially in the volume of cylinder 3412 of the sleeve of the vacuum cylinder 3410. The user inserts any type of liquid applicator, according to the present invention, into his mouth. The device 3000 can be activated by a sensor (pressure sensor, proximity sensor, etc.) or the device can be activated by the user. The cleaning cycle starts.
[0149] [000149] In the "downward movement" of piston rod 3460, application piston 3130 draws liquid from the bottom of cylinder volume 3412 into release volume 3114.
[0150] [000150] In the "upward movement" of piston rod 3460, application piston 3130 forces the liquid through the base port 742 of the reciprocating flow controller 710. The flow of liquids through the reciprocating flow controller 710 has been described previously using Figures 3c and 3d. In summary, when the reciprocating flow controller 710 in its first position (Figure 3c), liquid entering the release volume 3114 enters the reciprocating flow controller 710 through the base port 742. The liquid exits the reciprocating flow controller 710 through cover door 722, flowing into outlet tube 3010b. The return liquid, flowing through the outlet tube 3010a (not shown), re-enters the reciprocating flow controller 710 through the cover port 724. The liquid exits the reciprocating flow controller 710 through the base port 744. When the reciprocating flow controller 710 is in its second position (Figure 4d), the inlet liquid from release volume 3114 enters the reciprocating flow controller 710 through the base port 742. The liquid exits the reciprocating flow controller 710 through cover door 724 flowing into outlet tube 3010a. The return liquid, flowing through the outlet tube 3010b, re-enters the reciprocating flow controller 710 through the cover port 722. The liquid exits again from the reciprocating flow controller 710 through the base port 744. The reciprocation of the Cleaning in applicator 100 of Figure 1 is achieved by moving the reciprocating flow controller 710 from its first position to its second position. The change of the reciprocating flow controller 710 between its first and second positions is achieved by a worm gear, which is connected to the position adjuster 732 in the reciprocating flow controller 710. Although shown to be rotating continuously in this mode, it must be understood that the reciprocating flow controller 710 can be driven by separate means, like another engine. In addition, the time interval for changing the reciprocating flow controller 710 between its first and second positions can, in some embodiments, be between about 1 and about 100 seconds, or between about 2 and about 10 seconds, and can be changed over the course of cleaning / treatment.
[0151] [000151] In the present embodiment, the emptying section of the 3460 device is effective during the "upward movement" and "downward movement" of the piston rod 3000. The 3270 vacuum piston has double action and extracts the liquid from the applicator of liquid 100 in both the upward and downward movement of the vacuum piston 3270. Liquid flowing through the base port 744 of the reciprocating flow controller 710 flows through vacuum volumes 3275a or 3275b. The vacuum volume 3275a is the volume between the vacuum end disk 3250 and the vacuum piston 3270. The vacuum volume 3275b is the volume between the vacuum end disk 3290 and the vacuum piston 3270. During the "move to above "piston rod 3460, the liquid in the base port 744 is drawn into vacuum volume 3275b and simultaneously expelled from vacuum volume 3275a into cylinder volume 3412. During the" downward movement "of the piston rod 3460, the liquid in the base port 744 is drawn into vacuum volume 3275b and simultaneously expelled from vacuum volume 3275a into cylinder volume 3412. As noted, vacuum piston 3270 in this mode has a double action, drawing liquid from the applicator 100 in both the upward and downward motion of the vacuum piston 3270. So while the vacuum volume 3275b is drawing liquid from the base port 744, the liquid in the vacuum volume 3275a is being pumped into the v the volume of cylinder 3412. In contrast, while vacuum volume 3275b is extracting liquid from the base port 744, liquid in vacuum volume 3275a is being pumped into cylinder volume 3412. During the "upward movement" of the rod piston 3460, liquid in vacuum volume 3275a is pumped into cylinder volume 3412. During "downward movement" of piston rod 3460, liquid in vacuum volume 3275b is pumped into cylinder volume 3412.
[0152] [000152] The cycle continues with cycles comprising "upward movements" and "downward movements" of piston rod 3460 with liquid movement through device 3000, as described in the steps above.
[0153] [000153] The ratio between the total volume of the vacuum volumes 3275a and 3275b and the release volume 3114 can be any value, such as 1: 1, optionally, about 3: 1 or more, or about 4: 1 or more . The 3130 application piston only releases liquid in one "half" of the pumping / emptying cycle, while the 3270 vacuum piston works in both halves of the cycle. The 3270 double-acting vacuum piston also provides vacuum during half the movement, when the 3130 application piston is not releasing liquid, increasing the opportunity to recover liquid from applicator 100, as well as eliminate additional liquid that has leaked from liquid applicator 100 into the oral cavity. Tests have shown that a minimum volumetric ratio of 3: 1 between emptying liquid and releasing liquid by movement provided the necessary vacuum to minimize leakage into the oral cavity from liquid applicator 100 when the applicator has a gingival seal marginal, which can occur in modalities of a universal liquid applicator (designed to adapt to a range of people) 100.
[0154] [000154] In some embodiments, the 3270 vacuum piston has a unique action. However, a 3270 double-acting vacuum piston may have some advantages.
[0155] [000155] In some embodiments, the volume of cylinder 3412 may have an air separator to reduce foaming. In addition, a breathing passage may be necessary so that the pumping / emptying system is not too pressurized and crashes / fails. In addition, there may be a wall to separate the 3412 cylinder volume into two halves, to further reduce the chance of liquid splashing out of the breathing passage.
[0156] [000156] In general, cylinder volume 3412 is vented, as more liquid is being released into cylinder volume 3412, from the emptying system that is being extracted from the release system. The excess (air) is expelled from a breather in the 3412 cylinder volume. The breather can use a valve, such as a conical valve, so that air can escape, but it cannot enter the reservoir from the same opening, or a valve bidirectional or ventilation hole. To further reduce the loss of liquid through the breather, a wall can be used to divide the 3412 cylinder volume into two parts. One side contains the supply line, and the other side contains the breather. To improve the separation of air from the liquid in the 3412 cylinder volume, an air separator can be placed in the reservoir, below the supply line. When the liquid falls from the supply line into cylinder volume 3412, it passes through an air separator, which can be a solid plate with holes. This allows the liquid to pass, while removing entrained air and helping to separate the two liquid states (liquid versus gas). The air separator can have several designs, such as a solid sloped shelf with holes, a spiral slope, a spiral slope with holes, two or more levels of sloped slots with holes, several spiral slopes similar to several start points for threads (bottle caps, etc.), lumps located sporadically that the liquid reaches when it falls, aiding separation.
[0157] [000157] In one embodiment, the base unit is a portable, one-piece unit with a rechargeable battery, it has a piston pump driven by an engine for the application of liquid, it is a mechanism to control the flow of liquids, it maintains the temperature within a specified range, it has a modular design and ergonomics well suited to the user's hand. When the hand tool is in the base station, it will recharge the battery, the liquid reservoirs in the hand tool will be refilled from those in the base station, and samples and / or diagnostic information will be exchanged with the base. It can also go through a cleaning process.
