    FIELD OF THE INVENTION
    [001] The present invention relates, in general, to systems and methods to prevent contamination of access doors. In particular, this description discusses an antimicrobial access cover that is configured to receive an access door from an intravascular device, an inner surface of the antimicrobial access cover being treated with an antimicrobial agent. BACKGROUND OF THE INVENTION
    [002] In the fields of medicine and health, a patient's skin can be perforated in a variety of ways and for a variety of reasons. In one example, a cannula or an intravenous (“IV”) catheter is forced through the patient's skin into an internal space, such as the patient's vasculature. In this example, the IV cannula or catheter can be used to infuse a fluid (eg, saline, medication, and / or total parenteral nutrition) into the patient, extract fluids (eg, blood) from the patient, and / or monitor various parameters of the patient's vascular system. The cannula or IV catheter generally comprises a distal end that is positioned within the patient's vasculature, and a proximal end that is located external to the patient's vasculature. As such, a doctor can access the patient's vasculature through the exposed proximal end of the IV catheter.
    [003] Although an IV catheter is convenient to provide prolonged access to the patient's vasculature, the exposed portions of the catheter are susceptible to contamination by various strains of bacteria and viruses. In fact, it is estimated that each year thousands of patients in the United States alone develop some form of bloodstream infection that is caused by pathogens that have been communicated to the patient through or due to an IV catheter or other IV access device, such as a hypodermic needle. Many of the bacterial pathogens that cause these catheter-related bloodstream infections are introduced into the patient's vasculature through repeated attempts to access the patient's vasculature through an exposed portion of the IV catheter. Bacterial colonies that develop on the exposed portion of the IV catheter are transferred to the patient using a needle or syringe that is inserted into the exposed proximal portion of the IV catheter.
    [004] Generally, these catheter-related bloodstream infections cause disease in patients and, in some cases, death. In addition, due to the fact that some infections are caused by bacterial strains (for example, Methicillin-resistant Staphylococcus aureus (“MRSA”) and Vancomycin-resistant Enterococci (“VRE”) that are resistant to antibiotics, such infections can be difficult to treat and may become more prevalent.In addition, due to the fact that patients having a bloodstream infection may require additional medical treatment, catheter-related bloodstream infections may also be associated with increased medical costs.
    [005] In an attempt to limit bloodstream infections (ie, catheter-related infections) in hospitals, outpatient clinics, home health care settings, and other health care settings, many have implemented health techniques. For example, many medical service providers have placed a strong emphasis on wearing gloves, washing their hands, and washing the exposed portion of the IV catheter before inserting a needle or syringe. Some medical service providers have developed a medical device cover that includes a cleaning solution, as taught in U.S. Patent Application Serial Number 12 / 877,519, which is incorporated herein in its entirety for reference. However, the demands of some medical emergency situations generally make it impossible to use currently available sanitary techniques.
    [006] So, although there are currently methods and systems to reduce bloodstream infections, challenges remain. Consequently, it would be an improvement in the technique to increase or even replace current techniques with other techniques. SUMMARY OF THE INVENTION
    [007] The systems and methods of this description have been developed in response to problems and needs in the art that have not yet been fully resolved by the infusion systems and methods currently available. Therefore, these systems and methods are developed to provide safer and more efficient rapid infusion procedures.
    [008] In some implementations of the present invention, a device is provided to prevent contamination of an access door, the device including an access cover having an internal surface that defines a space to receive a portion of the access door, the inner surface also includes an antimicrobial agent. In some implementations, the access port is a portion of an intravenous or intravascular device, such as a y-port. In other implementations, the access door is a male or female luer of an intravascular device. Additionally, in some aspects of the present invention, the access port consists of at least a syringe, a catheter, a catheter connector, a needle, a piece of intravenous tubing, and / or an inlet or outlet valve for a medical device , such as a centrifuge or a dialysis machine.
    [009] In some aspects of the invention, an access cover is provided that is configured to cover and thereby protect an exposed portion of the access door, thus preventing contamination of the access door by bacteria or viruses. In some implementations, an access cover is provided that is connected to a portion of the access door. For example, in some implementations, the access cover is connected or attached to the access door via a handle. In other implementations, an access cover is attached to the access door using a hinged handle. In addition, in other implementations, the access cover is slidably coupled to the intravascular device. Additionally, in some implementations, the access cover is pivotally coupled to one of the access door and the intravascular device.
    [0010] The antimicrobial agent is generally provided on a surface of the access cover in such a way that when the access cover is placed on the access door, the antimicrobial agent is in direct contact with an exposed portion of the access door. In some implementations, the antimicrobial agent is applied directly to the access cover. In other embodiments, the antimicrobial agent is applied to a material (such as a sponge, foam, or gel) that is applied to a surface of the access cover. Therefore, when the access cover is placed adjacent to the access door, the antimicrobial agent maintains contact with an exposed or external portion of the access door.
    [0011] In some implementations of the present invention, a method is provided to prevent contamination of an access door. Some aspects of the invention provide steps for providing a lid having an inner surface that defines a space for receiving a portion of the access door, applying an antimicrobial agent to a portion of the inner surface, and attaching the lid to the access door. In some implementations, the access port is an intravenous or intravascular device. In other implementations, an additional step is provided where the antimicrobial agent is retained by a material disposed within the inner surface of the lid.
    [0012] Additionally, in some implementations of the present invention, an access port adapter, or an intravenous device adapter, is provided, having a body that includes a proximal end and a distal end, the proximal end having a first coupling surface for receiving a first upstream intravascular device, and the distal end has a second coupling surface for receiving a second downstream intravascular device. The access door adapter also includes a cover or access cover attached to the body of the access door adapter, the cover having an internal surface that defines a space to receive a portion of the access door, and a antimicrobial agent disposed within the inner surface of the lid.
    [0013] In some aspects of the present invention, the first and second coupling surfaces are threaded. In other aspects of the invention, a material is disposed within the inner surface of the lid that is capable of receiving and storing an antimicrobial agent. The material generally includes adsorbent or absorbent properties that allow the antimicrobial agent to be stored within the material. In some implementations, the material includes at least a sponge, a gel, a foamy material, a woven material, a nonwoven material, or a polymeric material.
    [0014] The present invention further includes methods for making an antimicrobial IV access cover, the method including steps for attaching an access cover to a portion of an intravenous device, the intravenous device having an access port , and inserts an antimicrobial agent into an inner surface of the access cover, the inner surface of the access cover being configured to receive an exposed portion of the access door. The method for making the antimicrobial IV access cover further includes steps for articulating coupling the access cover to a body portion of the intravenous device, as well as modifying the fixed connection between the access cover and the intravenous device with several other resources, discussed in detail later.

    [0029] The modalities of the present invention will be better understood with reference to the drawings, with similar numerical references indicating identical or functionally similar elements. It will readily be understood that the components of the present invention, as generically described and illustrated in the figures, can be arranged and designed in a wide variety of different configurations. Therefore, the following more detailed description, as represented in the figures, is not intended to limit the scope of the invention as claimed, however, it is merely representative of the presently preferred embodiments of the invention.
    [0030] The systems and methods of the present invention are generally designed for use in combination with a vascular infusion system capable of delivering an infuser to a patient's vascular system. Referring now to Figure 1, an antimicrobial IV access cover 10 is shown, according to a representative embodiment of the present invention. In some embodiments, the cap 10 prevents contamination of an access port 20, such as a y-port of an intravenous tube 30. In some embodiments, the cap 10 further comprises a loop 12 through which the cap 10 is coupled to a portion of the access door 20. In this way, the lid 10 can be removed from the access door 20 without being placed elsewhere or lost. In some embodiments, the lid 10, the handle 12 and the access door 20 comprise the same material. In other embodiments, the lid 10, the handle 12 and the access door 20 comprise two or more materials. In addition, in some embodiments, access port 20 comprises at least one intravenous access port, a PRN adapter, a Posiflow access port, a Q-Syte access port, a Maxiplus access port, and a Clearlink access port. . Access door 20 can further include any door or other structure that can be used to access a patient's vasculature.
    [0031] Referring now to Figure 2, a cross section of an access port 20 and an IV access cover 10 is shown. In some embodiments, the access port 20 comprises a portion of an intravenous tube 22. In other embodiments, the access port 20 comprises a portion of a catheter tubing adapter 28, a first and a second end 24 and 26 of the catheter tubing adapter being equipped with an intravenous tubing section, thus allowing , a flow between the sections of the intravenous tubing, through the adapter 28.
    [0032] The lid 10 generally comprises an inner surface 14 that defines a space for receiving a portion 16 of the access door 20. The inner surface 14 further defines a space for storing an antimicrobial agent 40. In some embodiments , the antimicrobial agent 40 comprises a material, a solution, a compound or a coating that prevents the colonization of unwanted batteries and viruses. In some embodiments, the antimicrobial agent 40 is selected from the group consisting of chlorhexidine gluconate, chlorhexidine acetate, PCMX, Trichloro, silver sulfadiazine, and the like. In other embodiments, the antimicrobial agent 40 comprises a topical antibiotic, such as Mupirocin, bacitracin and the like.
    [0033] In some embodiments, the antimicrobial agent 40 is applied directly to the inner surface 14 of the access cover 10. In other embodiments, the antimicrobial agent 40 is retained within the inner surface 14 of the access cover 10 through a material, such as as a spongy material, a gel material, a foamy material, a woven material, a non-woven material, and / or a polymeric material. The antimicrobial agent 40 is applied to the inner surface 14 of the lid 10 such that when the lid 10 is placed on the access door 20, the antimicrobial agent 40 contacts an opening surface 32 of the access door 20. Thus Thus, the antimicrobial agent 40 prevents the colonization of bacteria and / or viruses inside the access door 20.
    [0034] Referring now to Figure 3, in some embodiments, the access cover 10 comprises a portion of an intravenous device adapter 50. The adapter 50 comprises, in general, a proximal end 52 having a first threaded surface 62 for receiving an upstream intravenous device (such as a male syringe luer, not shown), and a distal end 54 having a second threaded surface 64 to threadably receive an downstream intravenous device 60, such as a catheter 60. From there In this way, adapter 50 allows the addition of an access cover 10 to an intravenous downstream device 60 which would otherwise not include an antimicrobial access cover 10.
    [0035] The distal end 54 is threadedly coupled to the downstream intravenous device 60 through the second threaded surface 64, thus preventing bacterial colonization between the adapter 50 and the downstream intravenous device 60, as shown in Figure 4. not being used, the proximal end 52 is positioned inserted inside the inner surface 14 of the access cover 10 such that the antimicrobial agent 40 is in direct contact with the proximal end 52. When ready for use, the cover access port 10 is removed from the proximal end 52 thus allowing a threaded connection between the threaded surface 62 and an upstream intravenous device (not shown).
    [0036] A person skilled in the art will appreciate that the interaction between the access cap 10 and the intravenous device adapter 50 can be performed by any number of different techniques. For example, in some embodiments, the access cover 10 is attached to the outer surface 56 of the adapter 50, as shown in Figure 4. However, in some embodiments, the access cover 10 comprises a handle 70 having a loop 72 , defining a distal end of the loop 70, the loop 72 being positioned around the second threaded surface 64 of the distal end 54, as shown in Figure 5.
    [0037] With reference to Figure 6, in some embodiments, the access cover 10 further comprises a plurality of threads 18 formed on the inner surface 14 of the cover 10, so the cover 10 can be threaded coupled to the first threaded surface 62 of the proximal end 52. In addition, in some embodiments, the loop 70 further comprises a second loop 74 that defines a proximal end of the loop. The second loop 74 is fixed in a groove 32 provided on an external surface of the access cover 10, thus allowing free rotation of the access cover 10 by screwing the access cover 10 to the proximal end 52 of the adapter 50 .
    [0038] In some embodiments, the loop 80 comprises a loop 82 configured to move within a channel 56 formed on an external surface of the adapter 50, as shown in Figures 7A-7E. Referring now to Figure 7A, in some embodiments, the access cover 10 is removed from the proximal end 52 by first moving the access cover 10 in an upward and backward direction 76. Once the access cover 10 you have removed proximal end 52, the access cover and handle 80 are moved in a downward direction 78, thereby completely exposing proximal end 52, as shown in Figure 7B. The proximal end 52 is capped again by reversing the movements through which the access cover 10 has been removed from the proximal end 52.
    [0039] In some embodiments, the handle 80 also comprises a lever 84 by means of which the user can move the handle 80 in a proximal direction 86 with one hand, thus advancing the access cover 10 in one direction proximal which results in an access cover 10 being removed from proximal end 52, as shown in Figures 7C and 7D. In some embodiments, the access cover 10 is oriented away from the intravenous device adapter 50 due to the outwardly directed tension provided in the handle 80. Therefore, when the access cover 10 is advanced beyond the proximal end 52, the access cover access 10 automatically jumps away from proximal end 52, thus providing unobstructed access to proximal end 52. The access cover is reapplied to proximal end 52 by forcing access cover 10 towards adapter 50 until the opening of the cover is aligned with the proximal end 52. The access cover 10 is then slid in a distal direction over the proximal end 52, thus causing loop 82 of loop 80 to return to its initial position within channel 56 of the adapter 50. In some embodiments, the access cover 10 is twisted by the user in such a way that no portion of the cover 10 overlaps the adapter 50, as shown in Figure 7E. The access cover 10 and the handle 80 are then slid in a distal direction 88 to resume the initial position of loop 82 within channel 56 of adapter 50.
    [0040] In some embodiments, the intravenous device adapter 50 further comprises a hinged antimicrobial cap 100, as shown in Figures 8A and 8B. The access cover 100 can comprise a different design in relation to the access cover 10. For example, in some embodiments, the access cover 100 comprises a platform 102 having a surface 104 against which the antimicrobial agent 40 is applied. In some embodiments, the platform 102 further comprises a lever 110 or cable through which the access cover 100 is manipulated by the user, with one hand, to remove the access cover 100 and the antimicrobial agent 40 from the proximal end. 52 of adapter 50.
    [0041] In some embodiments, the access cover 100 is pivotally coupled to the adapter 50 via a hinged handle 120. The hinged handle 120 includes a hinged joint 122 that moves the access cover 100 between a closed position (as shown) in Figure 8A) and an open position (as shown in Figure 8B). In some embodiments, the hinge joint 122 guides the access cover 100 against the proximal end 52 when in the closed position. In other embodiments, the hinge joint 122 guides the access cover 100 away from the proximal end 52 when in the open position. Therefore, the user can move the access cover 100 between the open and closed positions as desired to access a patient's vasculature.
    [0042] Referring now to Figures 9A and 9B, in some embodiments, the handle 130 comprises a loop 132 that defines a distal end of the handle, and a hinge joint 140 coupled to the platform 102 of the hinge cover 100, which defines the end proximal loop 130. Loop 132 is generally configured to pass through a groove or channel 56 of adapter 50 between the proximal and distal positions. When in a proximal position (as shown in Figure 9A), access cover 100 is in a closed position such that antimicrobial agent 40 is in contact with proximal end 52 of adapter 50. Handle 130 comprises, furthermore, a lever 134 or cable through which the user can, with one hand, move the handle 130 between the proximal and distal positions. When moved to a distal position (as shown in Figure 9B), access cover 100 is moved to an open position such that access cover 100 is removed from proximal end 52. In some embodiments, access cover 100 it is automatically moved from the closed position to the open position as a result of the user sliding the handle 130 in a distal direction. In other embodiments, the user first turns the access cover 100 to an open position and then slides the handle 130 to the distal position.
    [0043] In some embodiments, the handle 150 comprises a loop 152 that defines an intermediate portion of the handle 150, as shown in Figures 10A and 10B. Loop 152 is generally configured to sit within a groove or channel 56 of adapter 50 that maintains the position in which loop 150 is attached to adapter 50. In some embodiments, the interaction between loop 152 and channel 56 provides a pivot point or fulcrum 154 for handle 150. Therefore, when the lever portion 160 of handle 150 is pushed inward towards the distal end 54 of adapter 50, handle 150 hinges around fulcrum 154 thus doing with the access cover 100 being removed from the proximal end 52 in an outward direction, as shown in Figure 10B. When the lever portion 160 is released, the access cover 100 is returned to its initial position which results in an antimicrobial agent 40 in contact with the proximal end 52, as shown in Figure 10A.
    [0044] Referring now to Figures 11A and 11B, in some embodiments, the handle 170 comprises a rigid lever having a proximal end coupled to the access cover 100, and a distal end coupled hingedly to the intravenous device adapter 50. The handle 170 further comprises a cable or support 174 to facilitate manipulation of a rotated position of the handle 170 by the user in relation to the adapter 50.
    [0045] The hinge connection 172 between the handle 170 and the adapter 50 allows the handle 170 to be hinged or rotated between a closed position (as shown in Figure 11A) and an open position (as shown in Figure 11B). In some embodiments, the hinge connection 172 is spring loaded such that the handle 170 is oriented in the closed position. In some embodiments, Adapter 50 further comprises a stop 180 which prevents further rotation of handle 170 when in the closed position.
    [0046] A user accesses the proximal end 52 of the adapter 50 by pushing the support 174 in a backward direction 182, thus causing the access cover 100 to be displaced from the proximal end 52, as shown in Figure 11B. The support 174 is configured in such a way that a user can manipulate the position of the access cover 100 with one hand, thereby releasing the user's other hand to attach an intravenous device to the proximal end 52 of the adapter 50. Upon release of the support 174, the access cover 100 automatically rotates in a forward direction 184, thus returning the access cover 100 to its initial position which results in an antimicrobial agent 40 resuming contact with the proximal end 52, as shown in Figure 11A.
    [0047] In some embodiments, a section of intravenous tubing 240 comprises a male luer connector 250. The male luer connector 250 allows access to intravenous tubing 240. For example, in some embodiments, an infusion device, such as a syringe (not shown), is attached to the intravenous tubing 240 through a threaded connection between the male luer connector 250 and the syringe. In some embodiments, an exposed surface of the male luer connector 250 is protected by a hinged cover with spring 260, as shown in Figures 12A-12D. For example, in some embodiments, the hinged spring cap 260 comprises a set of distal threads, thus allowing the hinged spring cap 260 to be threadedly coupled to the male luer connector 250. In other embodiments, the hinged cap with spring 260 is press-fit to the outside diameter of the male luer connector compartment. In addition, in some embodiments, the hinged spring cap 260 comprises a set of proximal threads 262 thus allowing the hinged spring cap 260 to be threadedly coupled to a syringe or other infusion device.
    [0048] In other embodiments, the hinged spring cap 260 is fitted over the male luer connector 250 in such a way that the threaded surface proximal to the male luer connector 250 passes through a body portion of the cap 260 and is positioned inside the cap 260. As such, the male luer connector 250 can still be accessed by manipulating the cap 260 to reveal the proximal threaded surface of the male luer connector 250.
    [0049] In some embodiments, the spring hinged lid 260 comprises a first flap 264 and a second flap 266, each of which is hingedly coupled to a body portion of the spring hinged lid 260. In some embodiments, the first and second flaps 264 and 266 are additionally pivotally coupled to a body portion of the lid 260, thus allowing an open position, as shown in Figures 12A and 12B, and a closed position, as shown in Figures 12C and 12D. In addition, in some embodiments, the first and second flaps 264 and 266 are spring loaded, such that flaps 264 and 266 are oriented in the closed position, with the proximal ends of flaps 264 and 266 being in contact with each other. the others. The flaps 264 and 266 are manually oriented in the open position by pressing the distal ends of the flaps 264 and 266 inwards towards the body of the spring hinged lid 260. In some embodiments, the spring hinged lid 260 opens when the flaps open. 264 and 266 are tightened, thus exposing the female connection of the luer connector for system connection access.
    [0050] In some embodiments, the flaps 264 and 266 also comprise an internal surface 268 and 270, respectively, which form a seal when they are in a closed position. In some embodiments, the internal surfaces 268 and 270 are coated with an antimicrobial agent, in accordance with the teachings of the present invention. Therefore, when in the closed position, the exposed proximal surfaces of the male luer connector 250, or the threads proximal threads 262 of the cap 260, are contained within the antimicrobial agent coating of the flaps 264 and 266, thus preventing contamination unwanted activity.
    [0051] Referring now to Figures 13A-13D, in some embodiments, a cover 280 is provided having a cover 282 that is pivotally coupled to a body portion 290 of cover 280. Body portion 290 comprises, in In general, an internal space to receive an access port or other intravenous device. In some embodiments, the internal space of the body portion 290 comprises a set of threads for receiving a threaded access door. In other embodiments, the internal space of the body portion 290 is simply snapped to the outside diameter of a male luer connector housing.
    [0052] The cover 282 comprises an inner surface 284 that forms a closed end of the inner space when the cover 282 is in a closed position, as shown in Figures 13A and 13B. In some embodiments, the inner surface 284 further comprises an antimicrobial agent 40, in accordance with the teachings of the present invention.
    [0053] In some embodiments, the cover 282 further comprises a lever 294. The lever 294 comprises a first end 286 hingedly coupled to the body portion 290, and a second end hingedly coupled to the cover 282. The lever 294 further comprises a joint 300 by means of which the cover 284 and the second end 288 pivot in an open position when lever 294 is pressed inwardly towards body portion 290, as shown in Figures 13C and 13D. In some embodiments, a channel 310 is provided in the body portion 290, thus allowing the lever 294 and the joint 300 to be pressed through the body portion 290 and into the internal space of the body portion 290. Upon release of the lever 294 , cover 282 returns to its closed position, as shown in Figures 13A and 13B.
    [0054] The present invention can be incorporated in other specific forms without diverging from its structures, methods, or other essential characteristics as widely described and claimed in the following parts. The described modalities should be considered in all aspects only as illustrative, and not restrictive. Therefore, the scope of the invention is indicated by the appended claims, instead of being indicated by the previous description.
