BACKGROUND OF THE INVENTION
[001] The present invention relates to a method and apparatus for use in isolating an individual and, in one example, to a method and apparatus for isolating a patient in a health care facility, such as a nursing ward. hospital, or the like. DESCRIPTION OF PREVIOUS TECHNOLOGY
[002] The reference in this specification to any previous publication (or information derived from it), or to any matter that is known, is not, and should not be considered as an acknowledgment or admission or any form of suggestion that the previous publication (or information derived from it) or known matter forms part of the common general knowledge in the field of engagement to which this specification relates.
[003] Infection control in hospitals and other health care facilities is becoming increasingly important with an increase in the incidences of infectious diseases, drug-resistant infections, or the like. Such infections can have severe consequences, particularly in patients with an already compromised immune system, resulting in longer hospital stays, higher treatment costs and higher mortality. Estimates indicate that, in some health care institutions, infection levels can be in the range of 10-20%, meaning that infections acquired in medical facilities represent a significant proportion of annual health care spending.
[004] Infections are typically transmitted by a number of different mechanisms, including contact transmission, droplet transmission and airborne transmission. Current best practice for reducing infection rates is typically based on basic hygiene measures, such as regular hand washing, surface sanitization and equipment sterilization, to thereby prevent infection from other patients. However, the effectiveness of such measures is limited, and World Health Organization standards indicate that patients with infections or those suspected of having infections should be isolated from other patients. This can prove difficult with many facilities without adequate resources and space available to separate infected patients.
[005] Numerous solutions have been proposed for such problems.
[006] EP-0.619.108 describes a closure for isolation of a patient including an external frame and a flexible envelope suspended and pending on the frame. The envelope has portions of base, top, two sides, portions of front and rear wall. One of the portions of the side or front wall is fitted with a lockable entry device that allows the patient to enter. There is an opening in one of the wall portions adapted with an integral filter device adapted to filter infectious particles from the air and cooperate with a pump device, and a valve device that allows unidirectional air passage from the outside to the side of within closure. The pump device extracts air through said filter device which creates a negative pressure inside the closure, whereby air flows in the valve-closure-filter device direction, ensuring that no contaminants escape from the inside of the closure to the side. out.
[007] US2004074212 describes a patient isolation unit including a foldable frame body, a flexible envelope made of a flammable resin sheet that can be attached to the assembled frame body, and an exhaust fan to discharge or exhaust air from the envelope. The hood includes a UV lamp, a HEPA filter (High Efficiency Particulate Air) and a blower.
[008] However, these arrangements have numerous drawbacks. For example, the need to keep a tightly sealed envelope makes the apparatus complex and therefore expensive. The arrangements are also difficult to assemble, as well as requiring the arrangement to be assembled with the patient subsequently being moved into the envelope, which can be inconvenient and which can prevent the arrangements from being used in some circumstances. Finally, these arrangements typically require the doors to be opened manually, by hand meaning that infectious materials can be transferred to the door when it is being opened, leading to subsequent transmission forward, and thereby limiting the efficiency of the arrangements.

[00122] An example of an apparatus for use in isolating an individual, such as a patient, will now be described with reference to figures 1A to 1D.
[00123] In this example, the apparatus 100 includes a frame 110, which, in use, is movable between collapsed and assembled configurations. A body 120 is supported by the frame 110, so that when the frame 110 is in the assembled configuration, the body 120 defines an internal volume 130 to contain an individual, such as a patient, in a bed 131, to thereby substantially isolate the individual from a surrounding environment, such as a hospital ward or similar.
[00124] Apparatus 100 also typically includes a door actuator 140 supported and, in particular, mounted both on and within the frame 110. Door actuator 140 is for moving a door 142 between open and closed positions, as shown in the figures 1A and 1B, respectively. In the closed position, the door closes the internal volume, while, in the open position, the door gives access to the internal volume, thereby allowing users, such as doctors, to access the individual when necessary, still isolating the individual at other times.
[00125] In this way, the above-described arrangement provides an apparatus for isolating an individual in an environment, such as a medical facility, hospital ward, or the like.
[00126] The use of a collapsible frame 110 allows the apparatus 100 to be provided in an operational configuration, shown in figures 1A to 1C, with the frame 110 mounted and the body 120 attached, when it is necessary to isolate an individual. However, the apparatus 100 can also be provided in a storage configuration shown in figure 1D, in which the frame 110 is collapsed, when isolation from an individual is not necessary. This allows the device to be conveniently stored and quickly assembled when required.
[00127] The use of a suitable body 120 can allow a sufficient degree of isolation to be provided to significantly reduce infection rates. For example, although the apparatus may be hermetically sealed, this is not essential and, more typically, the apparatus is designed merely to help provide a barrier for contamination by at least one of solid, contact, fluid and droplet contaminant. As part of this, a lower edge of the body can be adapted to fit a surface, such as a floor, on which the apparatus is arranged, thereby preventing contaminants from passing between the body and the floor. This could be achieved using a variety of techniques, such as using an adhesive arrangement, as will be described in more detail below, although alternatively a heavy or similar arrangement may be used.
[00128] Additionally, the device acts as an alert for individuals that the isolated individual is infectious or suspected of being infectious, thereby serving to remind individuals about hygiene requirements, such as washing hands and the like, which additionally helps protect against contact transmission. Thus, even without airtight seal, the apparatus 100 operates to significantly reduce the opportunity for infection, for example, through contact or transmission by droplets.
[00129] The exposed arrangement allows the body to be formed of a suitable flexible sheet material, such as a water resistant cloth, application of plastic sheets, or the like, meaning that the body can be manufactured light and inexpensive, and allowing that the body is disposed of after use. The use of a disposable body can additionally help to reduce incidences of infection.
[00130] In addition, the use of a suitable door and door actuator can allow entry and exit without a user having to touch the door, which can additionally assist in reducing the spread of infectious materials. For example, the door may include one or more curtains 142 movably mounted on a rail, with actuator 140 including at least one, and more typically, two pedals 141.1, 141.2, coupled to curtains 142 by means of a cable or the like. This can provide a pedal system that allows hands-free operation of the curtain door, allowing users to open and close the door without having to touch the door. In one example, the pedals project into and out of the frame, allowing the door to be actuated from both inside and outside the internal volume.
[00131] However, it is clear that other actuator arrangements could be used. In a particular example, this is achieved using an electric motor supported by the frame and coupled to at least one of an actuator or sensor switch. However, electrical / electronic, pneumatic, hydraulic, chain, belt, or other similar arrangements, with the actuator being controlled using pedals, or other suitable arrangements, such as buttons or electronic sensors, such as proximity or motion sensors, control voice, or the like, can be used. In an additional example, sensors can be adapted to detect an identity of individuals trying to open the door, for example, using an RFID (Radio Frequency Identity) sensor and an associated tag used by the individual. This can then be used to register an identity of individuals accessing the device 100, which can be used, for example, for infection tracking, or to allow access only to authorized personnel, as those skilled in the art should realize.
[00132] Several additional features will now be described.
[00133] In one example, frame 110 supports at least one assembly for receiving medical items. The assembly could be of any suitable form, and could include, for example, assemblies coupled to the frame 110, such as a shelf, a wire mesh, a beam on which items are suspended, or the like. Typically, however, the apparatus includes at least one, and more typically, two panels 151, 152, which include one or more assemblies incorporated into them.
[00134] In this example, a first panel 151 includes at least one assembly for receiving medical items, shown in general by 151.1, 151.2, 151.3, 151.4, 151.5. Thus, apparatus 100 can be used to support instruments, documentation, equipment, protective clothing, disposal bags, cleaning materials, hand sanitizing fluid, a waste receptacle, or the like.
[00135] Additionally, a second panel 152 can act as a billboard, allowing information related to the patient to be displayed. In one example, the bulletin board can be made of material that can be written using a non-permanent marker, or the like, allowing patient details such as name, identifier or the like to be easily displayed. The warning panel 152 may also include at least one 152.1 assembly, such as staples, pockets, or the like, for receiving items such as documents, X-rays, patient notes or the like. The warning panel can also act to display warning signs or notifications, for example, to alert individuals, such as medical personnel, visitors or the like, of the infection presented or suspected to be presented by the patient, and / or any precautions that need to be taken. taken as a result of this. Thus, for example, the sign could indicate that medical personnel must be authorized before entering, or similar. It is realized that this can allow medical personnel to access patient information, without having to enter the internal volume 130, thereby reducing the likelihood of transmission of any infections.
[00136] The second panel 152 also acts to jointly support a shelf 153, which, in the storage configuration, rests on top of the collapsed frame and can act to support articles, while, in the operational configuration, the shelf is stored in a arrangement coast to coast with the second panel 152.
[00137] When the device 100 is in the operational configuration, the panels 151, 152 are arranged on either side of the door, thereby providing users with easy access to the items and information stored on the notice board. This allows items to be conveniently stored outside the internal volume to prevent unwanted contamination of the items, while still ensuring that the items are easily available, if required. In addition, by providing one or more waste receptacles, this can allow materials removed from the internal volume to be immediately discarded, thereby further reducing the risk of spreading infection. In one example, a trash receptacle can be for penetrating objects only, as this allows a relatively small receptacle to be used. Additionally, or alternatively, however, a receptacle could be adapted to receive medical clothing, gloves, instruments, or the like, and it is realized that this will depend on the preferred configuration.
[00138] Furthermore, when the frame 110 is in the collapsed configuration shown in figure 1D, the panels can be provided on the outside of the frame 110, thereby allowing items to be mounted and retained on the panels. This allows the device to function as a trolley, allowing items and the device 100 to be stored in it, and to be moved around a medical facility as needed.
[00139] Thus, in an example, the apparatus 100 can function both to isolate an individual, and as an infection control, PPE trolley (Personal Protective Equipment), equipment trolley, or other suitable trolley. With the provision of a dual-use configuration, this allows the device to be provided in an infirmary, functioning as a trolley so that the device does not occupy an unnecessary storage environment. In the event that a patient is found to be infectious or suspected of being infectious, the device can be quickly mounted around the patient, as will be described in more detail below. Thus, it is clear that the device can be retained in an infirmary as a trolley of accessible equipment while it is not being used, or used to isolate a patient while in the operational configuration. Even in the operational configuration, equipment and other items provided in the equipment trolley are still accessible, meaning that the storage functionality provided by the device is not impacted, even while the device is in the operational configuration.
[00140] In one example, panels 151, 152 and / or shelf 153 can be pivoted to frame 110, allowing panels 151, 152 and / or shelf 153 to move between locking positions, in which the panels fit the frame 110, and open positions. This can be used to assist in the movement of the frame 110 between the assembled and collapsed configurations, as well as allowing greater access to the internal volume, increasing the width of the door, as shown in figure 1C, which may be suitable in emergency situations.
[00141] Frame fitting by panels 151, 152 and / or shelf 153 can also act to lock the frame 110 in both the collapsed and assembled configuration, as well as act to assist in fixing the frame 110, thereby acting to reinforce the frame 110, when the panels are in locked positions, as will be described in more detail below. The panels can be fitted to the frame using any suitable technique, such as a magnetic coupling, latch, or the like. It is realized that similar functionality could be provided using other techniques, and thus, for example, locking the frame could be achieved using any latch mechanism.
[00142] An example of frame 110 will now be described in more detail with reference to figures 2A to 2F.
[00143] In this example, frame 110 includes several vertical legs 201, 202, 203, 204, 205, 206, 207 interconnected by several side connecting elements 221, 222, 223, 224, 226. In this example, seven legs are shown , but it is realized that this is not essential, and four or more can be used. A collapsible curtain rail 225 can also extend across a front of the frame 110 to support curtains 142 in use.
[00144] While any frame configuration 110 can be used, in the current example, two sets of three legs 201, 202, 203; 204, 205, 206, are arranged along the respective sides of the frame 110, the legs in each set being interconnected by connection elements 221, 224 and the sets being interconnected by connection elements 222, 223, 226 so that the frame 110 has a substantially cube-shaped configuration in the assembled configuration. Leg 207 is coupled to leg 206 by means of connecting beams 208 extending laterally between legs 206, 207. Leg 207 is positioned between legs 203, 206, partially extending through a front of the frame for hereby providing additional support for port 142, as well as supporting port actuator 140 and associated pedals 141.1, 141.2.
[00145] As shown for leg 201, legs 201, 202, 203, 204, 205, 206, 207 can be made of multiple sections 201.1, 201.2, and are telescopic, allowing frame 110 to be moved between a raised position , shown, for example, in figure 2A, and lowered position, shown, for example, in figures 2B to 2F.
[00146] Legs 201, 202, 203, 204, 205, 206, 207 may include a telescopic system predisposed, for example, using gas struts, spring mechanisms, linear actuators, lead screws, a counterweight, or the like, to thereby support, at least partially, the weight of the frame 110 and the body 120, thereby making it easier to lift the frame 110. For example, the legs could be predisposed to the raised position so that a user simply needs to unlock the legs, allowing the frame 110 to lift automatically, although other arrangements can be used. Legs 201, 202, 203, 204, 205, 206, 207 can also be locked in either the raised or lowered position, preventing inadvertent raising or lowering of the frame 110.
[00147] The connection elements 221, 222, 223, 224 can be of any suitable form. For example, connecting element 221 includes pairs of scissor arms connected to pivot 221.1, 221.2 attached to legs 201, 202, 203, by means of fixed and movable clamps 221.3, 221.4. This allows the scissor arms to move between an extended position, shown, for example, in figure 2A, and retracted positions, shown, for example, in figures 2B to 2F. It is realized that connection elements 222, 223, 224 typically have a similar configuration, and therefore will not be described in further detail. It should also be noted that, in one example, the connecting element 223 can incorporate the rail 225, so that the rail forms at least part of the arms of the scissor mechanism. The connecting element 226 is typically hingedly mounted on the frame by means of hinges 226.2, 226.3 and additionally includes a single hinged joint 226.1, which can be over-extended, so that the connecting element 226 extends above a level of the remainder of frame 110. This allows it to be used to support body 120, as will be described in more detail below. Hinges 226.2, 226.3 can be used to provide additional support for legs 202, 205, thereby preventing unwanted leg movement.
[00148] It is noted, in one example, that the scissor arms of the connecting elements 221, 222, 223, 224 on adjacent sides of the frame are independent, meaning that the frame can be expanded in first and second orthogonal directions independently. For example, the frame can be extended in the width direction and then subsequently extended in the length direction, as will be described in more detail below.
[00149] In one example, the panels 151, 152, which are attached to a pivot on the legs 216, 213, respectively, are adapted to fit the connecting element 223. This acts to assist in the fixation of the legs 216, 213 in relation to the connecting element 223, thereby improving the strength of the frame 110 in the assembled configuration.
[00150] Frame 110 typically includes wheels 211, 212, 213, 214, 215, 216, 217 which, in this example, are mounted on respective legs 201, 202, 203, 204, 205, 206, 207. Wheels 211, 212, 213, 214, 215, 216, 217 can be of any suitable form, such as casters, or the like, allowing the frame 110 to be supported movably on a surface, such as the floor, so that the apparatus 110 can be easily moved. The wheels 211, 212, 213, 214, 215, 216, 217 can also be selectively lockable to assist the movement of the frame between the collapsed and assembled configurations, as will be described in more detail below.
[00151] It is noticed that the frame 110 is typically made of light, durable and robust materials, which can be cleaned using suitable cleaning products. For example, legs and connecting elements can be made of light metals such as aluminum, high density polymeric materials, such as HDPE (High Density Polyethylene), carbon fiber, glass fiber, or the like.
[00152] As shown in figures 3A to 3D, the body 120 typically includes a ceiling element 303 and several walls 301, 302 extending between a support surface and the ceiling element 303 when the apparatus 100 is in the operational configuration.
[00153] Body 120 and curtains 142 are typically made of a lightweight flexible sheet material substantially water resistant, such as cloth, PVC (Poly (vinyl chloride)), PE (Polyethylene) or the like, thereby providing a barrier to contaminants in the internal volume. In a preferred example, the material is a non-woven propylene cloth formed by continuous filament extrusion laminated to a PE film, used, for example, in disposable medical garments, but other materials could be used. In any case, it is noticed that the body 120 is similar in shape to a tent body, although this is not essential. Body 120 is typically removably mounted to frame 110, allowing body 120 to be discarded and replaced after use. The body 120 is also normally mounted into the frame 110 to thereby prevent the frame from being exposed to contaminants, with the body 120 being attached to the frame using any appropriate technique, such as strips, clamps or the like.
[00154] In use, walls 301, 302 can be adapted to fit the floor, thereby reducing the chance of contaminants passing under the walls. This can be achieved in any suitable manner, such as by using a heavy portion proximal to a lower edge of the walls, such as a heavy edge, or a beam that forms part of the frame 110 which attaches to the lower edge of the walls and impels the walls against the floor, or the like. More typically, however, an at least partially adhesive material can be provided at a bottom edge of the walls, thereby adhering the walls to the floor. In one example, this is achieved by using double-sided tape, or tape attached to the walls with the adhesive side facing away from the wall, although other arrangements can be used.
[00155] Additionally, perforations 302.1 or slots or other access points can be made or provided in the body 120 to give access to external utilities, such as oxygen, suction, energy and the like, as will be described in more detail below. Such perforations or openings can be provided in the rear walls 302, since, in use, this typically rests on a wall of the medical facility containing connections to the external utilities, as will be described in more detail below. However, perforations or similar cracks can also be provided in the ceiling or other parts of the body to allow access, for example, to lamp fittings, or other equipment. Additionally, the body may include openings or semi-porous portions, such as panels, to allow air to circulate. Typically they are provided on the ceiling to minimize transmission of projected droplets and fluids, although this is not essential, and suitable sigh arrangements could be used.
[00156] The side walls 301 may also include portions of window 301.1, typically formed from an optically transparent material. This allows individuals to see the individual without having to enter the internal volume, while still providing the individual with a view of the infirmary or other surrounding environment, which is important to ensure that the individual does not feel too isolated. It is also noticed that window blinds (not shown) can be provided, allowing the windows to be covered, thereby providing privacy for the individual, in the required manner.
[00157] The body 120 typically includes at least two wall elements. In the current example, three wall elements are shown including two side walls 301 (only one side wall on the right side 301 is shown for the purpose of illustration, but the side wall on the left side would have a similar configuration) and a rear wall 302. A short front wall element (not shown) can also extend between the legs 206, 207, with a remaining front of the body being provided by the curtains 142. However, it is realized that other arrangements could be used. For example, the rear wall 302 could be omitted, with the side walls being attached to an infirmary wall using tape or the like.
[00158] Curtains 142 can be manufactured using materials similar to body 120. Curtains 142 could additionally include magnetic portions, such as a magnetic strip, along the edges of the curtain, allowing the curtains to be attached to the frame 110 and / or walls 301, and / or to allow two curtains 142 to be interconnected. Alternatively, the curtains 142 can be formed integrally with the walls, or welded on the walls, for example, using hot welding, as those skilled in the art should realize.
[00159] An example of rail 225 will now be described with reference to figure 4.
[00160] In this example, rail 225 includes two rail elements 225.1, 225.2, with first ends hingedly coupled to frame 110, for example, legs 203, 207, and second ends hinged interconnected by means of respective hinges 225.3, 225.4, 225.5. This allows the rail 225 to bend as the frame 110 is collapsed or opened. The hinges can incorporate a locking mechanism to lock the rail in an operative position, thereby helping to support the weight of the curtains 142.
[00161] The rail incorporates a cable opening / closing mechanism, with the cable extending through or around hinges 225.4, 225.5 and being attached to pedals 141.1, 141.2, allowing these to open and close the door, respectively. The cable can be attached to a car system mounted externally on the rail that supports the curtains. The carriage system can be attached to the cable by means of a mechanical fixing extending through a slot in the rail. However, alternatively, the carriage system can be coupled to the cable by means of magnets, so that a magnetic force operationally connects the carriage system to the cable. This allows the car system to be operationally disconnected from the cable, so that the curtains can be opened manually. This allows the door to be opened quickly, for example, during an emergency, as well as avoiding the need to include a crack in the rail, which can house contaminants or the like. It can be seen from the above that the term cable is not intended to be limiting and could cover any elongated flexible element, such as a rope, wire, belt or the like.
[00162] In one example, apparatus 100 may be provided in place around a bed, while the patient is still in bed. This generally involves positioning the apparatus 100 adjacent to the bed and, in particular, adjacent to an end corner of the bed. The frame 110 is then extended in a first direction perpendicular to a length of the bed, before being moved over the bed in a second direction parallel to the length of the bed. At this point, the frame 110 rests on a wall provided behind the bed. Thereafter, the frame 110 is extended in the second direction so that the frame generally extends around the bed, with the body 120 being supported by the frame 110 to define the internal volume 130 with the bed 131 contained therein. It is noticed that this process allows the apparatus 100 to be assembled while the patient remains in situ, thereby assisting additionally in the infection control.
[00163] An exemplary process for assembling the apparatus 100 to isolate a patient bed will now be described in more detail with reference to figures 5A to 5L.
[00164] For the purpose of this example, a patient is considered to be situated in a bed located in a cubicle in a hospital ward, and it is determined that there is a need to isolate the patient, for example, because the patient has been diagnosed with an infection, or is suspected of having an infection. In this scenario, apparatus 100 would typically be provided in the ward to operate as an infection control or PPE trolley, as those skilled in the art should realize.
[00165] In this example, the device 100 is transferred in the storage configuration and positioned in the front left corner of the patient's cubicle area, with the panel 151 facing out of bed 131 and the wall of the cubicle 500, as shown in figure 5A . The bed 131 is lowered, if necessary, as shown by the arrows 501, and at least one of the wheels 214, 215, 216, 217 on the left side of the frame 110 is optionally locked to hold the frame 110 in position during extension of the frame.
[00166] In one example, when frame 110 is in the collapsed configuration, panel 151 engages frame 110 to lock the frame in position. In this way, panel 151 can be opened by swinging panel 151 outwardly, as shown by arrow 502.2 in figure 5B, allowing frame 110 to be mounted. In addition, shelf 153 is hinged from the top of frame 110 and supported on panel 152, as shown by arrow 502.1.
[00167] If not already assembled, the body 120 can be attached at the top of the frame 110, although the body can also be assembled later in the process, as will be mentioned below. This is achieved in any suitable manner, such as attaching the strings or clamps at attachment points on the frame 110. In one example, the correct orientation of the body 120 can be assisted by matching colors in the clamps and mounting points provided on the frame. The body can also be partially retained in the package, so that the body remains in a raised position and remains predominantly sealed to maintain hygiene of the body 120.
[00168] Initially, the frame 110 is extended in the direction of the arrow 503, holding and pulling one or more of the legs 201, 202, 203 and the panel 152. The frame is pulled across the width of the cubicle, so that the legs 201 , 202, 203, 204, 205, 206, 207 are provided on either side of the bed. During this process, if the body 120 is assembled, it will unfold as the frame extends. Thus, during this process, the frame is extended in the width direction, still remaining contracted in the direction of the length.
[00169] Once the frame is fully extended through the cubicle, the user typically verifies that the connecting elements 222, 223 and the curtain rail 225 are fully extended and locked in position. The user can also push the central connection element 226 upwards until it locks into position, as shown by arrow 503.1, allowing the ceiling element 303 to be coupled to it, if this has not already occurred. Arrange the connecting element 226 raised above the level of the frame around it, this can raise the center of the ceiling, providing additional space in the internal volume. After the ceiling element 303 is attached to the connecting element 226, any remaining connection between the upper body 120, such as around the edge of the ceiling element 303, and the frame 110 is made. Billboard panel 152 is also swung out from the snap position shown in figure 5C to the open position shown in figure 5D, as shown by arrow 503.2.
[00170] Then, all the wheels 211, 212, 213, 214, 215, 216, 217 are unlocked and the frame 110 is moved on wheels on the bed 131, as shown by the arrows 504, with the legs 201, 202, 203 and legs 204, 205, 206, 207 encapsulating the bed 131.
[00171] If not already done, the frame 110 can then be moved to the raised position, for example, by unlocking, lifting and locking the telescopic legs 201, 202, 203, 204, 205, 206, 207 again. , in the event that the telescopic legs are predisposed, the frame 110 can automatically lift as the legs 201, 202, 203, 204, 205, 206, 207 are unlocked. Alternatively, this may require the frame to be lifted by the user.
[00172] Once the frame 110 is lifted and the legs 201, 202, 203, 204, 205, 206, 207 locked in the raised position, the body 120 can be removed from the remaining packaging, or otherwise uncoupled, to allow that unfolds on the floor, as shown by arrow 505 in figure 5F.
[00173] Then, the rear corner wheels 201, 204 of the frame 110 that are closest to the wall of the cubicle 500 are locked, before the front of the frame 110 is then rotated back onto the bed 131, as shown by the arrows 506 in Figure 5G, extending the walls 301 of the body 120 around the bed 131, so that the frame is extended lengthwise. It can be seen that by extending the frame separately in the width direction and then subsequently in the length direction, it is guaranteed that the frame 110 does not occupy an excessive amount of the environment in the infirmary during assembly, making it easier to assemble the isolation apparatus , even when space is limited. In this regard, traditional frames typically require the frame to be extended both width and length simultaneously, making it difficult to mount them in the confined space of an infirmary or other internal space.
[00174] The aforementioned process also allows the frame 110 to be mounted on the bed 131 while the patient remains in situ. This avoids the need to move the patient, which may increase the risk of infection in other individuals in the vicinity, as well as potentially adversely affecting the patient's health.
[00175] At this point, the user verifies that the connection elements 221, 224 are fully extended and optionally locked in position. The position of the frame 110 can be adjusted according to need, before all the wheels 211, 212, 213, 214, 215, 216, 217 are locked. If not already assembled, the body 120 can be attached to the frame 110, with the walls 301, 302 being lowered in position, as previously described.
[00176] The walls 301 are attached to the legs 201, 202, 203, 204, 205, 206 of the frame 110 using fittings provided, as shown by the arrows 507 in figure 5H. After that, the curtains 142 are attached to the curtain rail 225 and the pedals 141.1, 141.2 are pulled through slots in the body 120, as shown in 508, in figure 5I. Pedals 141.1, 141.2 are used to open and close curtains 142 thereby attaching the magnetic coupling between the carriage system and the cable.
[00177] Typically, the side and rear walls 301, 302 (and any front wall element) can then be attached to the floor with double-sided adhesive tape or otherwise attached, as shown by 509 in figure 5J. In one example, the adhesive tape is attached to the body walls during manufacturing, so that the user simply needs to remove a layer of tape coverage, and apply the tape directly to the floor.
[00178] Connections on the necessary equipment (eg wall oxygen) 520 can be accessed through openings created using the perforations 302.1 in the rear wall of the body 120. Tape 521 can then be provided around the openings to limit the transmission of agents infectious to the infirmary wall surfaces, as shown in figure 5K.
[00179] It is realized that, although the above-described method of assembling the device is particularly beneficial, it should not be limiting and, in practice, any method for changing the device to the operational configuration can be used. For example, the frame could be assembled, before the frame is moved on wheels over the bed, if space allows. Additionally, the process described above focused on the assembly of the device by a single person, but it is clear that two or more people can be involved. This can make it easier, for example, to avoid the need to lock the wheels to extend the frame, and to lift the frame 110 on each side simultaneously.
[00180] This results in a disposable isolation environment that stands on its own without hands using an opening that, in one example, can easily be mounted around a patient, in situ. In addition, as shown in figure 5L, the device 100 can be scaled for use in existing wards, mounting below curtain rails in situ 510, allowing the device to be quickly deployed in a wide range of clinical environments. In addition, the apparatus 100 can be used as a trolley to store medical items, or the like, for easy access.
[00181] A second example of an apparatus for use in isolating an individual, such as a patient, will now be described with reference to figures 6A to 6C. In this example, apparatus 600 is roughly similar to that described in the example in figures 1A to 1D, and similar features are denoted by similar reference numbers increased by 500.
[00182] In this example, the device 600 includes a frame 610, which in use is movable between collapsed and mounted configurations. A body 620 is supported by frame 610, so that when frame 610 is in the assembled configuration, body 620 defines an internal volume 630 to contain an individual, such as a patient in a bed 631, to thereby substantially isolate the person from a surrounding environment, such as a hospital ward or similar.
[00183] Apparatus 600 also typically includes a door actuator 640 supported and in particular mounted both on frame 610 and within it. The door actuator 640 is for moving a door 642 between open and closed positions, as shown in figures 6A and 6B, respectively. In the closed position, the door closes the internal volume, while, in the open position, the door gives access to the internal volume, thereby allowing users, such as doctors, to access the individual when necessary, still isolating the individual at other times . In this example, the door actuator is in the form of a button connected to an electronic control system that controls the opening and closing of the door, for example, using an electric motor or the like, thereby facilitating hands-free access to the volume internal 630. It is noticed that a similar button can also be provided inside the frame to open and close door 642 inside the internal volume. However, this arrangement is not essential and other arrangements such as a cable-operated pedal from the previous example could be used.
[00184] The apparatus 600 includes panels 651, 652, which include one or more assemblies incorporated in it. The first panel 651 includes at least one assembly for receiving medical items, shown in general by 651.1, 651.2, 651.3, 651.4, 651.5, while the second panel 652 can act as a billboard, and can also include assemblies (not shown) to receive medical items or equipment.
[00185] When the device 600 is in the operational configuration, the panels 651, 652 are arranged on either side of the door, thereby providing users with easy access to stored items and information on the notice board. When the frame 610 is in the collapsed configuration shown in figure 6C, the panels can be provided on the outside of the frame 610, thereby allowing items to be mounted and retained on the panels. This allows the device to function as a trolley, allowing items and the device 600 to be stored in it, and to be moved around a medical facility as needed. In addition, in this example, the first panel 651 is attached to the frame 610, so that when the frame is raised, the first panel 651 remains in a lowered position, and a similar arrangement can also be used for the warning panel 652 , so that this remains in a lowered position when the frame 610 is raised. It can be seen that this reduces the weight of the 610 frame that needs to be lifted, as well as helping to maintain a lower center of gravity, which increases stability.
[00186] Therefore, it is realized that otherwise the operation of the apparatus 600 is substantially similar to that of the apparatus 100 described above, and this will therefore not be described in detail.
[00187] An example of frame 610 will now be described in more detail with reference to figures 7A to 7E.
[00188] In this example, frame 610 includes five vertical legs 701, 702, 703, 704, 705 interconnected by three side connecting elements 721, 722, 723 and a collapsible curtain rail 725 that extends across the front of the frame 610 to support curtains 642, in use. Leg 705 is coupled to leg 704 by first panel 651 and a secondary panel 708, extending laterally between legs 704, 705. Leg 705 is positioned between legs 702, 704, partially extending through the front of the frame 610 to thereby provide additional support for port 642, as well as support port actuator 640.
[00189] The legs 701, 702, 703, 704, 705 can be made of multiple sections 701.1, 701.2, 702.1, 702.2, 703.1, 703.2, 704.1, 704.2, 705.1, 705.2, and are telescopic and optionally predisposed, allowing the frame 610 is moved between a raised position, shown, for example, in figure 7A, and a lowered position, shown, for example, in figure 7D. In this example, the panel 651 is attached to the lower portions 704.2, 705.2 of the legs 704, 705, while the secondary panel 708 is attached to the upper sections 704.1, 705.1 of the legs 704, 705. As a result of this configuration, the first panel 651 that supports medical equipment remains in a lowered position, while secondary panel 708 is raised. This minimizes the weight that needs to be lifted, while still ensuring that the legs 704, 705 are interconnected along their length, thereby increasing structural rigidity.
[00190] Connecting elements 721, 722, 723 include pairs of scissor arms connected to pivot attached to the legs 701, 702, 703, by means of fixed and movable clamps, allowing the scissor arms to move between an extended position, shown, for example, in figure 7A, and retracted positions, shown, for example, in figure 7D. The legs 701, 703 include guards 701.4, 701.5, 703.4, 703.5 for receiving ends of the connecting element 722, when in a stowed position. Under guards 703.4, 701.4 can also support fan / filter arrangements to filter air that leaves or enters the internal volume 630.
[00191] However, in this example, unlike the apparatus 100, the connection elements 721, 722, 723 are mounted on the lower leg sections 701.2, 702.2, 703.2, 704.2, 705.2, so that the connection elements 721, 722 .723 are not lifted as the legs are lifted to the lifted position. This helps to maintain a lower center of gravity, and provides additional stability in use. Despite this, once the body 620 is assembled, the combination of body 620 and collapsible curtain rail 725 can help ensure that frame 610 has sufficient structural rigidity.
[00192] Note that, in one example, the scissor arms of the connecting elements 721, 722, 723 on adjacent sides of the frame are independent, meaning that the frame can be expanded in first and second orthogonal directions independently. For example, the frame can be extended in the width direction and then subsequently extended in the length direction, as will be described in more detail below.
[00193] Collapsible curtain rail 725 typically includes two rail elements 725.1, 725.2, with first ends pivotally coupled to frame 610, for example, legs 702, 705, and second ends interconnected by a hinge 725.3. The rail may incorporate a cable opening / closing mechanism, similar to the one described above with respect to apparatus 100, although alternative arrangements may be used. A specific exemplary curtain rail including an alternative arrangement like this will be described in more detail below.
[00194] Frame 610 typically includes groups of one or more wheels 711, 712, 713, 714, 715 mounted on respective legs 701, 702, 703, 704, 705, and can be of any suitable form, such as lockable casters, or the like, allowing frame 610 to be movably or fixedly supported on a surface.
[00195] In this example, the legs 701, 702, 703, 704 include a top piece 701.3, 702.3, 703.3, 704.3 which in use receives ceiling supports 701.6, 702.6, 703.6, 704.6 to support a body ceiling 620. The ceiling supports 701.6, 702.6, 703.6, 704.6 typically form part of the ceiling. If the body is installed when the frame is in a collapsed configuration, the ceiling supports would be pivoted to a stowed position, shown in figures 7D and 7E. However, when the frame is in an assembled configuration shown in figures 7B and 7C, the body applies a force to the ceiling supports, so that the ceiling supports pivot to the raised position, as shown. It is noticed that the predisposition of the ceiling supports to the retracted position tenses and consequently supports the ceiling in use, also also raising the ceiling to increase the height of the internal volume.
[00196] In this regard, as shown in figures 8A to 8C, the body 620 typically includes a roof element 803 and several walls 801, 802 extending between a support surface and the roof element 803 when the apparatus 600 is in the operational configuration.
[00197] Body 620 is substantially similar to body 120. However, in this example, ceiling 803 and ceiling supports 701.6, 702.6, 703.6, 704.6 are attached to the corners of the ceiling, as shown, for example, using fasteners or the like . However, it is clear that, alternatively, other arrangements could be used, for example, by arranging the ceiling supports mounted on the frame and then removably attached to the ceiling in use. When the body 620 is mounted on the frame 610, the ceiling brackets 701.6, 702.6, 703.6, 704.6 are coupled to the top pieces 701.3, 702.3, 703.3, 704.3, with the ceiling brackets 701.6, 702.6, 703.6, 704.6 being predisposed for thereby tensioning and lifting the ceiling and, consequently, helping to support the ceiling, when the ceiling is in an assembled configuration.
[00198] The process for assembling the apparatus 600 to isolate a patient bed is substantially similar to that of the apparatus 100 and therefore will not be described in detail. However, some of the key stages will be described with reference to figures 9A to 9E.
[00199] The bed 631 is initially moved out of the 900 wall. The body 620 is coupled to the frame by inserting the ceiling supports 701.6, 702.6, 703.6, 704.6 into the top pieces 701.3, 702.3, 703.3, 704.3. The apparatus 600 is moved close to the wall 900, close to the bed, with the outermost wheels of the bed being locked and the legs 701, 702, 703, 704, 705 raised, as shown by the arrow 901.
[00200] The frame 610 is then extended in the direction of the arrow 902, pulling the legs 701, 702, so that the frame 610 extends between the bed 631 and the wall 900. It is realized that the frame 610 has to be extended behind the bed first so that the connecting element 723 can be positioned between the bed 631 and the wall 900. During this process, the curtain rail 725 dismantles and, once the frame is fully extended, the user can check if the connecting element 723 and the curtain rail 725 are fully extended and locked in position, as shown by 903. If the body 620 is mounted, it can then unfold, as shown by arrow 904, so that it passes between the bed 613 and wall 900. Billboard panel 652 is also swung outward, as shown by arrow 905. Then wheels 712, 714, 715 are unlocked and frame 610 is moved on wheels on bed 631 , as shown by arrows 906, making sure that the connection elements 721, 723 are fully extended and locked in position.
[00201] The body 620 can be attached to the legs 701, 702, 703, 704 before the side and rear walls 801, 802 are attached to the floor with double-sided adhesive tape or otherwise attached, as shown by the dotted line 908 on the figure 9E. In one example, the adhesive tape is attached to the body walls during manufacturing, so that the user simply needs to remove a layer of tape coverage, and apply the tape directly to the floor. Thereafter, curtains 642 are attached to curtain rail 725 and connections to the necessary equipment (eg wall oxygen) 920 can be accessed through openings created using perforations in the rear wall of the body 620.
[00202] The above-described process also allows the frame 610 to be mounted on the bed 631 while the patient remains in situ. This avoids the need to move the patient, which can increase the risk of infection in other individuals in the vicinity, as well as potentially adversely affecting the patient's health.
[00203] The examples presented focused on the provision of an isolation device, which is aimed at the isolation of an individual particularly in relation to types of transmission of infection by touch and droplets. However, this is not essential and the device can be extended to provide protection against airborne transmission, thereby acting as an Air Suspension Infectious Isolation Environment (AIIR).
[00204] In order to provide protection against transmission by suspension in the air, it is typical to provide an air filter system, for example, using a HEPA filter, to thereby filter air extracted from the internal volume, and typically provide internal volume to a negative pressure (that is, at a lower pressure than the external environment). It is realized that a negative pressure can be maintained, even if the internal volume is not hermetically sealed, providing sufficient sealing and continuous pumping of air from the internal volume. In one example, negative pressure can be achieved if the body walls are sealed to the floor using tape, or the like.
[00205] An anteroom can also be provided adjacent to the door entrance, to provide additional sealing, as well as providing a place where contaminated materials, such as clothing or the like, can be removed and retained. In one example, an anteroom can be provided by attaching two of the isolation devices to each other. For example, the back wall of a first device can be removed, and then positioned adjacent to the front wall of a second device containing the patient. In this example, the first device acts as an anteroom, while the second device acts as the isolation room.
[00206] The first and second apparatus can be attached in any suitable manner and, in one example, this is achieved using a bonding strip that has double-sided tape arranged around each side of the bonding strip. This seals each isolation room together so that the overall arrangement includes both an isolation room and anteroom.
[00207] It is noticed however that other arrangements could be used, such as for the first device to customize a device with a smaller overall size, allowing it to function only as an anteroom. Alternatively, a separate door arrangement, similar to that of the current insulation device, could be used to insulate part of a corridor, or for several other uses.
[00208] In one example, a separate curtain rail apparatus like this may include legs that support an articulable curtain rail, the rail including two rail elements with first ends hingedly coupled to the legs and second ends interconnected by means of a hinge . The hinge can include a locking mechanism to lock the rail in an operative position. The hinge can be of any suitable shape, but in one example, it includes first and second body portions and where the locking mechanism includes locking screws to selectively fit the first and second body portions to thereby lock the hinge.
[00209] Each rail element can enclose an endless belt mounted on sprockets positioned at either end of the rail element, the sprockets on the second end of each rail being mechanically interconnected by a crazy gear, and the sprocket on the first end of one of the rail elements being connected to an electric motor, hereby allowing the belts to be moved, and in which, in use, a curtain is mechanically coupled to each belt so that movement of the belt allows the curtains to be open or closed.
[00210] An example of an independent curtain rail will now be described in more detail with reference to figures 10A to 10F.
[00211] In this example, curtain rail 1025 is supported by legs 1002, 1004, 1005, with legs 1004, 1005 being interconnected by a top piece 1004.3. The curtain rail 1025 includes two rail elements 1025.1, 1025.2, with first ends coupled to the legs of the frame 1005, 1002 by means of hinges 1025.4, 1025.5 and second ends interconnected by a hinge 1025.3. As shown in figures 10A, 10C and 10E, legs 1002, 1005 can be separated so that the rail moves from the retracted position shown in figure 10A to an assembled configuration shown in figure 10E.
[00212] It is realized that, in this example, the legs 1002, 1004, 1005 can be telescopic, allowing the curtain rail to be supported at any appropriate height. The telescopic legs 1002, 1004, 1005 can therefore be similarly shaped to the legs of the frames 110, 610, and can therefore be predisposed, for example, using gas supports, spring mechanisms, counterweights or the like, to support at least partially weight of the rail and consequently make it easier to lift the rail. In addition, it is realized that the length over which the rail extends (corresponding, for example, to the width of the corridor that can be covered) can be adjusted, for example, by using telescopic sections or scissor elements connecting the legs 1004, 1005 and / or changing the top piece 1004.3 to allow variations in the overall length.
[00213] Once assembled, a curtain can be adapted on the rail, with an actuator being used to allow operation of the door without the use of hands. It is realized that this arrangement can be used to cover a corridor or the like, thereby allowing the isolation of an area to be provided.
[00214] In one example, the rail incorporates a cable opening / closing mechanism, similar to the one described above with respect to the apparatus 100 and 600. However, alternatively, a suitable electric motor and controller, or other similar arrangement can be used. A specific example will now be described in more detail with reference to figures 11A to 11F.
[00215] In this example, hinge 1025.3 includes a body 1101 including two portions of body 1101.1, 1101.2, each of which is coupled to a respective rail element 1025.1, 1025.2 and a cable 1102. A plate 1105 and spool 1106 are positioned between cable 1102 and body 1101, with cable 1102, plate 1105 and spool 1106 being fixed on shaft 1102.1, which is rotationally mounted on bodies 1101.1, 1101.2, thereby allowing relative rotation of body portions 1101.1, 1101.2 and cable 1102, while plate 1105 and spool 1106 remain fixed in relation to cable 1102.
[00216] The hinge 1025.3 additionally includes locking screws 1103, mounted in openings 1105.1 in the plate 1105. The plate 1105 is profiled in such a way that, as the cable 1102 and, consequently, the plate 1105 are rotated, the screws 1103 are propelled in an axial direction. The screws extend through the second body portion 1101.2, allowing the screws 1103 to move in or out of the recesses 1104 in the first body portion 1101.1 to thereby selectively lock or unlock the first and second body portions 1101.1, 1101.2 and, consequently, the 1025.3 hinge. The reel 1106 is coupled by means of a cable, link, chain, belt or the like (not shown) to a locking plate 1131, which selectively fits one of the locking openings 1131.1, 1131.2 in the hinge 1025.3, thereby locking the hinge 1025.3 in either the stowed or extended position. It should be noted that a locking plate 1131 would typically be provided on both rail elements with locking openings on both 1025.3, 1025.4 hinges, and that this is shown only for a 1025.3 rail and hinge element just for the sake of clarity . When the hinge 1025.5 is unlocked, the cable is wound on the spool 1106, thereby retracting the locking plate 1131 and releasing the hinge 1025.5, allowing the rail to be extended.
[00217] The rail element 1025.1, 1025.2 contains endless belts 1111, 1112 mounted on respective gear wheels 1111.1, 1111.2, 1112.1, 1112.2 at either end. The sprockets 1111.1, 1112.1 are axially aligned with the hinges 1025.3, 1025.4. The sprockets 1111.2, 1112.2 are coupled by means of shafts 1112.3, 1111.3 to the respective gear teeth 1112.4, 1111.4, which are in turn connected by a crazy gear tooth 1113 rotationally mounted on the shaft 1102.1. This arrangement allows rotation to be transmitted between the sprockets 1111.2, 1112.2 and, consequently, the belts 1111, 1112, so that the belts move in synchronism.
[00218] The 1111.1 sprocket is mechanically coupled by means of top angled gears 1142, 1143 on an 1141 shaft, which is in turn coupled to an 1140 motor, allowing the belts to be driven. It is noticed that cars can be driven by belts 1111, 1112, allowing the curtains to be opened and closed by the appropriate movement of belts 1111, 1112. In this regard, the curtains would be connected to the rail by means of a suitable car or other connector (not shown), which is, in turn, coupled to a corresponding belt of belts 1111, 1112, so that movement of the belts allows the curtains to be opened or closed, thereby providing an entrance to the door, which can be open and closed using operation without the aid of the hands of a sensor or key attached to the engine. It is realized that the edges of the curtain or a flexible skirt attached to the curtain and / or the frame can be fixed to the walls and / or a ceiling and / or aisle floor using tape, a mechanical beam, or other fixing mechanism, thereby helping to provide an isolation barrier across the corridor.
[00219] Thus, having a curtain rail 1025 extending across the aisle, the rail being supported on either side by respective legs 1022, 1024, 1025, this provides a barrier within the aisle. The use of two such barriers may allow part of the corridor to be isolated, so that this can function as an anteroom or, alternatively, the curtain apparatus of figures 10A to 10G could be used in conjunction with apparatus 100 or apparatus 600 for act as an anteroom.
[00220] It is realized that the above-described curtain apparatus could have several uses in addition to covering a corridor, and could be used in any situation in which a curtain is needed, regardless of whether insulation is required. For example, this could be used to provide a temporary exchange environment by extending the curtain rail through a corner of a room or the like. In addition, the collapsible curtain rail could be used as part of a display enclosure, where a curtain is used, but it is also necessary to be able to pack and transport the curtain rail easily. Therefore, it should be understood that the curtain rail can be used in a variety of situations and need not be limited to use in isolating individuals or equipment.
[00221] It is also noticed that the hinge and drive mechanism of figures 11A to 11F can be used in the examples presented as tracks 225, 725 of the apparatus 100 and 600, respectively. Thus, in this case, curtains 142, 642 can be operated using engine 1140, using appropriate controls.
[00222] Although the description presented has focused on the isolation of a patient with an infection, it is clear that the system could also be used in other scenarios, for example, to isolate immunodeficient patients from surrounding patients, or the like. In one example, during isolation of a patient to prevent the patient from being exposed to potentially infectious materials, the patient could be provided in the isolation apparatus. In an additional example, this could be positively pressurized in relation to the surrounding environment, thereby providing a hygienic environment in the enclosed space, which excludes external contaminants, for example, for the purpose of conducting work or procedures, although it is perceived that pressurization is not essential, and at least some insulation will be provided regardless of whether pressurization is used.
[00223] From the description presented, several resources were described in a single example. However, it is clear that the different resources could be used independently, and that their use together, although beneficial, is not necessarily essential.
[00224] In this specification and the following claims, unless the context otherwise requires, it should be understood that the word "understand" and variations such as "understand" or "comprising" imply the inclusion of an entire declared part or group of whole parts or steps, but not the exclusion of any other whole part or group of whole parts.
[00225] It should be understood that the term individual applies to any entity to be isolated and that this can include patients, as well as other individuals. The individual may also be a non-human individual, such as an animal, including, but not limited to, primates, domestic animals, performance animals, such as racehorses, or the like. In addition, the insulation device could also be used for equipment or other items, for example, in the event that they have been exposed to contaminants. Thus, even when a patient is removed from the isolation device, he can still continue to isolate any equipment contained in it, for example, until it can be cleaned and / or disposed of. The term individual must therefore encompass any item and not be limited to a biological entity, even though it is perceived that the techniques described above are particularly advantageous for use with biological entities.
[00226] Versed in the technique, they will realize that countless variations and modifications will become apparent. All such variations and modifications that will be apparent to those skilled in the art must be considered in accordance with the spirit and scope of the invention that appear in general described herein.
[00227] Although the example presented has focused on the use of the isolation apparatus in isolating an individual in the form of a patient, it is clear that the arrangement described above can be used whenever any form of isolation is necessary. For example, the insulation apparatus could be used to provide a portable spray paint booth, which could be assembled or positioned around an object or article to be painted, with the apparatus acting to support the spray painting equipment when provided in the trolley configuration. In this case, the device is still used in isolation of an individual, in the form of an object or article, preventing the spray paint from hitting the surrounding environment. Thus, it is realized that the device can be used in a wide range of circumstances and can be used to isolate any object or article, and that specific reference to patients as a preferred example, is not intended to be limiting.
