专利说明:

[0001] [0001] The present disclosure generally refers to a device for disinfecting and sterilizing access doors with, for example, male and female luer fitting and, in particular, for disinfecting and sterilizing devices capable of accommodating various types of connectors. Generally, exemplary embodiments of the present disclosure refer to the fields of the threaded fitting, including medical caps and medical disinfectant caps and, in particular, disinfectant caps and / or caps for use with fluid luer connectors. FUNDAMENTALS
[0002] [0002] Vascular access devices (VAD) are commonly used therapeutic devices and include intravenous (IV) catheters. There are two general classifications of VAD: peripheral catheters and central venous catheters. Bacteria and other microorganisms can enter a patient's vascular system from access hubs and ports / valves through connection with the DAV to supply the fluid or pharmaceutical. Each access hub (or port / valve or connection) is associated with some risk of transmitting a catheter-related bloodstream infection (CRBSI), which can be expensive and potentially lethal.
[0003] [0003] To decrease CRBSI cases and ensure that DAVs are used and maintained correctly, standards of practice have been developed, which include disinfectant and cleaning procedures.
[0004] [0004] Disinfectant caps have been added to the Society for Healthcare Epidemiology of America (SHEA) guidelines and early indications are that the caps will also be incorporated into the 2016 Infusion Nurses Standards (INS) guidelines.
[0005] [0005] In developed markets, when using an IV catheter, a needleless connector will normally be used to close the system and subsequently accessed to administer medication or other necessary fluids through the catheter to the patient. The INS Practice Standards recommend the use of a needle-free connector and state that it should be "consistently and thoroughly disinfected using alcohol, iodine tincture or chlorhexidine / alcohol gluconate combination before each access". Disinfection of the needle-free connector is ultimately intended to help reduce bacteria that may be living on the surface and possibly lead to a variety of catheter-related complications, including CRBSI. Nurses typically use a 70% isopropyl alcohol (IPA) pad to complete this disinfection task, doing what is known as "rubbing the hub". However, compliance with this practice is generally very low. In addition to the lack of compliance with "rub the hub", it was also observed through interviews with doctors that there is usually a variation in the rubbing time, in the drying time and in the number of times that the needleless connector is rubbed.
[0006] [0006] Along the sequence of procedures associated with the transmission of a microorganism that can cause a CRBSI, there are many risks of contact or contamination. Contamination can occur during mixing of the drug, fixation of a cannula and insertion in the access hub. Since the procedure for connecting to a VAD is very common and simple, the risk associated with entering a patient's vascular system has often been overlooked. Currently, risk to hospitals and patients is a substantial function of the diligence of the clinician making the connection, and that diligence is largely unmanageable.
[0007] [0007] Currently, caps for needle-free male connectors, needle-free female connectors, intravenous (IV) and hemodialysis lines use different designs and are therefore limited to the types of connectors to which the cap can be attached. Currently, male disinfectant cap devices exist to disinfect fluid luer connectors with ISO594-2 female thread and there are male disinfectant cap devices to disinfect fluid luer connectors with ISO594-2 male thread. However, there is no universal disinfectant cover device with features that allow interface with male and female threaded connectors. Thus, the previous disinfectant covers were designed to fit only one type of connector and were specific to a specific size and / or shape of the connector. Thus, a disinfectant device capable of accommodating various types of connectors, including male and female connectors, is required to optimize the disinfectant process.
[0008] [0008] In the example of medical applications, several conventional caps for closing a needle-free connector while not in use have been known for some time. In order to decrease cases of catheter-related bloodstream infection (CRBSI), disinfectant caps were originally disclosed in the US Patent Publication. No. 2007/011233 that issued as a US patent. No. 8,740,864 (full disclosures of both are incorporated by reference in this document) and introduced to the market. Disinfectant caps, such as those disclosed in the US patent. No. 8,740,864, are illustrated in Figures 1 and 2 in this document, where cover 1 includes a disinfectant pad 2 and cover 3 and cover 4 includes a disinfectant pad 5 and cover 7, as well as threads 6 in their circumference internal 8 to lock with the needle-free connector hub. On the other hand, other conventional lids may have similar characteristics, but exclude the disinfectant pad. SUMMARY

[0078] [0078] Disclosure modalities refer to a universal sterile cover for connection and disinfection of a medical connector, including male and female connectors. The male and female connectors can be male luer and female luer connectors. The cover arrangements comprise a casing and a projection. The cover comprises an integral body having a closed end and an open end. The side wall of the housing having a length L C extending from the closed end to an open end and defining a chamber. In one or more embodiments, the open end includes a peripheral shoulder that extends radially outward from the open end, defining an end face and an engaging surface. The projection having an internal wall surface having one or more threads adapted to engage a female luer connector. The outer wall surface of the projection having one or more threads sized and adapted to receive a male luer connector. The cover may further comprise absorbent material, a disinfectant or antimicrobial agent and a detachable seal and / or septum. The cover provides a mechanical barrier for connectors and contains an antimicrobial agent for disinfection. The limit of this disclosure allows the physician to streamline the disinfectant process.
[0079] [0079] With regard to terms used in disclosure, the following definitions are provided.
[0080] [0080] As used in this document, the use of "one", and "a" includes the singular and the plural.
[0081] [0081] As used herein, the term "catheter-related bloodstream infection" or "CRBSI" refers to any infection resulting from the presence of a catheter or IV line.
[0082] [0082] As used in this document, the term "Luer connector" refers to a connection collar that is the standard way of connecting syringes, catheters, needles with hubs, IV tubes, etc. each other. The Luer connector consists of male and female locking tubes, slightly tapered to better connect with just a simple pressure / twist fitting. Luer connectors can optionally include an additional outer edge of the thread, allowing them to be more fixed. The male end of the Luer connector is usually associated with a discharge syringe and can lock and connect to the female end located on the vascular access device (DAV). A Luer connector comprises a distal end, a proximal end, an irregularly shaped outer wall, a profiled central passageway for fluid communication from the barrel of a syringe to the hub of a DAV. A Luer connector also has a distal end channel that reliably attaches the Luer connector to a DAV hub and a proximal end channel that reliably attaches the Luer connector to a syringe barrel.
[0083] [0083] As would be readily appreciated by those skilled in the relevant technique, while descriptive terms such as "lock", "hole", "tip", "hub", "thread", "understanding, are not intended to limit any components that may be used in combinations or individually implement various aspects of the modalities of this disclosure.
[0084] [0084] The subjects exemplified in this description are provided to assist in the comprehensive understanding of exemplary disclosure modalities. Therefore, those skilled in the art will recognize that various changes and modifications to the modalities described in this document can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of known functions and constructions are omitted for clarity and brevity.
[0085] [0085] Exemplary modalities of the present disclosure provide limits that can reduce the number of types of devices and logistics currently needed in the hospital environment to connect, limit, and / or disinfect the fluid luer connectors with male and female threads, approximately in half, including on a single cover or device features, allowing it to be used with male and female threaded fittings.
[0086] [0086] In an exemplary implementation of the modalities of the present disclosure, a cover, connector cover or disinfectant cover includes integrated thread or threads and other resources in any and all combinations that allow the interface with the male and female threaded fittings.
[0087] [0087] According to other exemplary implementations of the modalities of the present disclosure, the configuration of the structural elements that make up the cover includes one or more anchored pins arranged in the inner cavity of the cover, the anchored pins comprising an internal thread to connect to the female medical connectors and an external thread to connect to male medical connectors, to facilitate fixing the cover in a female socket or in a male socket, respectively.
[0088] [0088] According to yet other exemplary implementations of the modalities of this disclosure, both male and female threads coincide with each other on the internal and external face of the threaded projection.
[0089] [0089] According to yet other exemplary implementations of the modalities of the present disclosure, the anchored pin can be in the form of projection and can be of a type of split thread in which the projection can bend, in order to allow a better fitting conformity interference with the fittings.
[0090] [0090] In accordance with yet other exemplary implementations of the modalities of the present disclosure, the female threads are sized and have a thread pattern that will engage with a standard ISO594-2 male fitting and / or dimensioned male threads and with a standard threads that fit with an ISO594-2 female insert. An example of an ISO594-2 type fitting is the Q style fitting.
[0091] [0091] In one or more modalities, the female connector can be selected from the group consisting essentially of needle-free connectors, catheter luer connectors, taps and hemodialysis connectors. In one or more modalities, the needle-free connector is selected from a Q-Syte, MaxPlus, MaxPlus Clear, MaxZero, UltraSite, Caresite, InVision-Plus, Safeline, OneLink, V-Link, ClearLink, NeutraClear, Clave, MicroClave, MicroClave Clear, Neutron, NanoClave, Kendall, Nexus, InVision, Vadsite, Bionector, etc.
[0092] [0092] In one or more modalities, the male connector can be an end of an intravenous tube, a tap or a male luer lock.
[0093] [0093] Before describing various exemplary embodiments of the invention, it should be understood that the disclosure provided is not limited to the details of construction or process steps set out in the description below. Dissemination is capable of other modalities and can be practiced or carried out in different ways.
[0094] [0094] With reference now to the drawings, in which similar reference numbers designate identical or corresponding parts throughout the various views, modalities of the present disclosure are described below.
[0095] [0095] A first aspect of the present disclosure relates to a cover 10 that includes a housing and a pin in the form of a projection. As shown in Figures 3A to Figures 7B, the housing 20 may include an upper wall 22, an essentially cylindrical side wall 26 that forms a first cavity 28 and an open bottom 23 formed by the cylindrical side wall 26 with an opening 27 in the first cavity 28 inside the housing 20 to receive a hub of a needle-free female connector or a needle-free male connector. In one embodiment, the projection 30 is integrally formed with the housing 20 and is positioned within the first cavity 28. The projection 30 includes an inner surface 31 and an outer surface 33, the inner surface 31 of the projection 30 defining a second cavity 40. In one or more embodiments, the cap 10 of the present disclosure has an internal thread 36 which has a size and height for engaging a threadable segment of a female connector, such as, for example, a female luer connector. Such connectors are generally and commonly used as catheters and other liquid-proof protective connectors in medical applications.

[0127] [0127] Figure 19 shows the cover with a view along the central axis A and from above. As is known, the side wall of the split threaded insert 130 has a radius R1, which substantially corresponds to a radius of the neck element of a male or female connector. The side wall of the split thread insert 130 tapers outward and extends with a radius R 2, which is greater than the radius R1 of the split thread insert 130. The radius R 2 corresponds substantially to the largest radius of the split thread insert 130, where a flange is formed to secure the split thread insert 130 to a recess formed on the inner surface of the housing 120.
[0128] [0128] In an exemplary implementation of the modalities of the present disclosure, projection 130 may be propped up, for example, having one or more gaps or cutouts 135. In an exemplary implementation, at least a portion of the propped projection 130 may be folded to allow for a better compliance of the interference fitting with the fitting, such as at least one male or female connector.
[0129] [0129] In yet another exemplary implementation, the projection 130 can extend essentially from the inner surface 125 of the upper wall 122 towards the bottom of the enclosure 120.
[0130] [0130] In a further exemplary implementation, the projection 130 can extend essentially parallel to the side wall 126.
[0131] [0131] In still a further exemplary implementation, the inner portion 132 of the cavity 128 may extend further inwardly towards the inner surface 125 of the upper wall 122 than the outer portion 134 that ends at the top, for example, as illustrated in the cross-sectional views of Figure 33.
[0132] [0132] In still an even more exemplary implementation, an internal thread profile 136 and / or the internal surface 131 can be essentially parallel or coincide with an external thread profile 138 and / or the external surface 133, respectively.
[0133] [0133] In an exemplary implementation of Figures 15-18, the projection 130 is illustrated as comprising two pins spaced by the cutouts 135 and extending essentially from the surface 125 of the upper wall 122. However, also within the scope of the disclosure are the covers comprising a unitary projection 130 without cutouts 135 and caps with projection 130 comprising any number of identical and / or different pins (in any dimensional characteristics, such as length, width, thickness or shape), provided that the projection 130 is configured to engage a female connector in relation to its internal surface and engage a male connector in relation to its external surface.
[0134] [0134] Figures 20-24 show a cross-sectional view of the projection of the split thread 130, showing the thread pattern of the inner thread 136 and the outer thread 138.
[0135] [0135] As shown in Figures 20-28, the outer threads 138 on the outer side wall of the split thread insert 130 extend in a helical pattern.
[0136] [0136] As shown in Figures 24 and 27, the internal threads 136 on the inner side wall of the split thread insert 130 extend in a helical pattern.
[0137] [0137] As shown in Figures 25-28, two or more removable inserts 130 can be joined by a connecting element 139.
[0138] [0138] As shown in Figures 29-30, the removable insert 130 can be positioned inside the first cavity 128. As shown in Figures 29-30, disposed within the cavity 128 is an insert with split thread in the form of a projection 130 ( which can be essentially cylindrical and coaxial with the side wall 126) having an inner surface 131 that defines an inner portion 132 of the cavity 128 and an outer surface 133 that defines and an outer portion 134 of the cavity 128. The split thread insert 130 is in the form of a projection 130 and comprises an internal thread 136 on its internal surface 131 to engage a female connector and an external thread 138 on its external surface 133 to engage a male connector.
[0139] [0139] In one or more modalities, as shown in Figure 31, the split thread insert 130 and the casing 120 can be joined by ultrasound welding or solvent resistant biocompatible adhesive. As shown in Figures 31-38, the split threaded insert 130 and housing 120 can also be locked via interference fit or quick fit. Boss / wedge portions can be arranged at the distal ends of the split thread insert 130 to provide a quick fit on the connection to the cover housing. The inner surface 125 of the upper wall 122 of the housing 120 may have a recess into which the shoulder / wedge of the insert can be inserted.
[0140] [0140] The shoulder / wedge portion of the split thread insert 130 is adapted to lock, temporarily or permanently, in the recess 124 on the inner surface 125 of the upper wall 122 of the housing 120. When the wedge portion of the split thread insert 130 it is mounted in the recess 124 on the inner surface 125 of the upper wall 122 of the housing 120, the recess is deformed and pressed to the side. When the wedge portion of the split threaded insert 130 passes through the recess edge, the recess edge tends to return to its original position, engaging the cam / wedge portion of the split threaded insert 130, thus maintaining the split threaded insert 130 in position in housing 120.
[0141] [0141] As shown in Figure 32, to prevent the insert from rotating in relation to the cover body, projections such as pins 30A, grooves 30B or other geometries such as tetrahedrons are present on the top wall 122 or on the side wall 126 of the enclosure or on removable insert 130, while the corresponding geometries are present in the other to receive projections.
[0142] [0142] As shown in Figures 33-35, the bridges 143 connecting the gaps 142 between the pins 144 restrict the deflection angle of said pins 144, increasing the safety of the engagement when the disinfectant cover is connected to the male or female connectors. As shown in Figures 33-35, the thickness and width of the bridges 143 can be adjusted to adjust / control the apparent rigidity, given a certain material property of the pins, modifying the desired deflection angle. The thickness of the bridge 143 can be the total or partial sectional thickness of the pins 144, including or excluding the thread profile. Referring to Figure 33, the shape of the split thread insert 130 may vary. The split thread insert 130 can have a variety of shapes, including, but not limited to, the shape of a trapezoid, an inverted trapezoid, a convex inner surface (for example, a paraboloid), concave inner surface, or a straight profile (i.e. , cylindrical or semi-conical). In one or more embodiments, the profile of the split thread insert 130 and / or the opening of the split thread insert 130 may vary. Split thread 130 and the split thread insert pins 130, as shown in Figure 33, can vary from 80-100 ° or 85-95 °, so the split thread insert 130 can have shapes including, but not limited to a, the shape of a trapezoid, an inverted trapezoid. In one or more modalities, as shown in Figure 33, it is 90 °. In one or more embodiments, the internal diameter of the split thread insert 130 is cylindrical.

[0159] [0159] Referring to Figures 43-50, according to exemplary embodiments of the present disclosure, a lid 210 comprises a housing 220 that includes an upper wall 222 with an internal surface 225, a side wall 226 (which can be essentially cylindrical ) with an inner surface 221, and an aperture 227 in a cavity 228. Aperture 227 is arranged at the bottom 223 of housing 220. The inner surface 225 of the top wall 222 can form a top of cavity 228. Arranged within cavity 228 is a projection 230 (which can be essentially cylindrical and coaxial with side wall 226) having an inner surface 231 that defines an inner portion 232 of cavity 228 and an outer surface 233 that defines and an outer portion 234 of cavity 228. The projection 230 it comprises an internal thread 236 on its internal surface 231 for engaging a female connector and an external thread 238 on its external surface 233 for engaging a male connector.
[0160] [0160] In an exemplary implementation, as shown in Figure 46, a shell seal 260 may be in the form of a film and be provided to seal opening 227 prior to use of cap 210, for example, by attachment to a surface of an edge 229 of an open bottom 223 of housing 220, as described for example in the above-mentioned previous applications.
[0161] [0161] The edge 229 of an open bottom 223 of the housing 220 may comprise a peripheral shoulder extending radially out of the annular side wall 226 at the open bottom 223 that defines an end face. The surface of the edge 229 of an open bottom 223 of the housing 220 also defines an engaging surface where a shell seal 260 can be attached.
[0162] [0162] Referring to Figure 46, in one or more embodiments, the shell seal 260 is arranged on the engaging surface of the open bottom 223 of the housing 220 to prevent the disinfectant or antimicrobial agent from leaving the cavity
[0163] [0163] In yet another exemplary implementation, the absorbent material 250 is a disinfectant element or elements in the form of a sponge soaked in IPA that can be supplied inside cavity 228, for example, in the vicinity of the inner surface 225 of the upper wall 222 of the inner part 232 and / or towards the top 239 of outer part 234 of cavity 228, for example, as described in the second aspect of the present disclosure.
[0164] [0164] Lid 210 can achieve disinfection when used in luer connectors by integrating a disinfectant or antimicrobial agent in cavity 228 of lid 210. The disinfectant or antimicrobial agent can be added directly to chamber 212 or the disinfectant or antimicrobial agent can be absorbed in sponges or foam material that fills the lid 210 chamber. The lid 210 was designed to be compatible when interacting with various disinfectants. In one or more embodiments, the disinfectant or antimicrobial agent may include variations in alcohol or chlorhexidine. In one or more embodiments, the disinfectant or antimicrobial agent is selected from the group consisting essentially of isopropyl alcohol, ethanol, 2-propanol, butanol, methylparaben, ethylparaben, propylparaben, propyl gallate, butyl hydroxyanisol (BHA), butylhydroxytoluene , t-butylhydroquinone, chloroxylenol, chlorhexidine, chlorhexidine diacetate, chlorhexidine gluconate, povidone iodide, alcohol, dichlorobenzyl alcohol, dehydroacetic acid, hexetidine, triclosan, hydrogen peroxide, colloidal silver, benzethonium chloride, benzene chloride octenidine, antibiotics and mixtures thereof. In a specific embodiment, the disinfectant or antimicrobial agent comprises at least one of chlorhexidine gluconate and chlorhexidine diacetate. In one or more embodiments, the disinfectant or antimicrobial agent is a fluid or a gel.
[0165] [0165] Compression of the absorbent material 250 towards the upper wall 222 of the housing 220 after connection to the female luer connector or the male luer connector allows the connector to contact the disinfectant or antimicrobial agent to disinfect the female luer connector or the male luer connector.
[0166] [0166] In an exemplary implementation of the modalities of the present disclosure, projection 230 can be propped up, for example, having one or more gaps or cutouts 235. In an exemplary implementation, at least a portion of the propped up projection 230 can fold to allow for a better compliance of the interference fitting with the fitting, such as at least one male or female connector.
[0167] [0167] In yet another exemplary implementation, the projection 230 may extend essentially from the inner surface 225 of the upper wall 222 towards the lower part of the housing 220.
[0168] [0168] In yet an additional exemplary implementation, the projection 230 may extend essentially parallel to the side wall 226. In yet an additional exemplary implementation, the inner portion 232 of the cavity 228 may extend further into the lid towards the surface inner 225 of the upper wall 222 than the outer portion 234 ending at the top 239. In an even more exemplary implementation, an internal thread profile 236 and / or the inner surface 231 can be essentially parallel or coincide with a thread profile outer 238 and / or outer surface 233, respectively.
[0169] [0169] Referring to Figures 48, according to exemplary modalities of the disclosure, the cap 220 can receive a tip or hub 272 from a female connector without a needle 270, for example, after a sealing film sealing cavity of shell 228 is removed or when the shell seal film is perforated, inside the inner portion 232 of the cavity 228 and fixes (for example, with thread) the tip of the needleless connector 270 inside the inner portion 232 of the cavity 228. One or more threads 236 may be sufficient to lock with a coupling feature 274 (such as one or more projections, terminals and / or thread) of a hub or tip 272 of the needleless connector 270, as described, for example, in the north patent applications American Companies No. 15 / 408,278 and 15 / 408,187, both deposited on January 17, 2017
[0170] [0170] Referring also to Figures 47-48, according to exemplary modalities of the disclosure, the cap 220 can receive a tip or hub 282 from a male connector without a needle 280, for example, after the removal of a sealing cavity of shell seal film 228 or when the shell seal film is perforated, inside the inner portion 232 of the cavity 228 and fixes the tip or hub 282 of the needleless connector 280 inside the inner portion 232 of the cavity 228, fixing ( for example, with thread) the collar 284 of connector 280 within the outer portion 234 of cavity 228. One or more threads 238 may be sufficient to lock with a coupling feature 286 (such as one or more projections, terminals and / or thread) the collar 284 of the needle-free connector 280.
[0171] [0171] In an exemplary implementation of Figure 43, the projection 230 is illustrated as comprising two pins spaced by indentations or gaps 235 and extending essentially from the surface 225 of the upper wall 222. However, also within the scope of the disclosure are the covers comprising a unitary projection 230 without any cutouts or gaps 235 and the caps with projection 230 comprising any number of identical and / or different pins (in any dimensional characteristics, such as length, width, thickness or shape), provided that the projection 230 is configured to engage a female connector with respect to its inner surface and engage a male connector with respect to its outer surface.
[0172] [0172] With reference to Figures 44-46, in one or more embodiments, the external surface of the side wall 226 comprises a plurality of gripping elements 290.
[0173] [0173] Cap 210 is made of any of several types of plastic materials, such as polycarbonate, polypropylene, polyethylene, polyethylene terephthalate, polylactide, acrylonitrile-butadiene-styrene or any other moldable plastic material used in medical devices. In one or more embodiments, the cap 210 comprises a polypropylene or polyethylene material.
[0174] [0174] In one or more modalities, when a hub of the needleless female connector is received inside the inner surface of the second cavity (40, 140, 240), the hub is fixed inside the inner surface of the second cavity (40, 140, 240), locking at least a portion of the internal thread with a coupling feature on the needleless female connector hub. In one or more embodiments, when a hub of the needle-free male connector is received within the inner surface of the second cavity (40, 140, 240), the hub is attached within the first cavity, locking at least a portion of the external thread on the surface projection with a coupling feature on a needle-free male connector collar when the collar is received within an outer portion of the second cavity (40, 140, 240).
[0175] [0175] In one or more embodiments, an inner portion of the second cavity (40, 140, 240) may extend further inwardly towards the upper wall than an outer portion of the second cavity (40, 140, 240) . In one or more embodiments, the profile of the internal thread can be essentially parallel or coincide with a profile of the external thread.
[0176] [0176] In one or more modalities, the internal thread and the external thread can include a pattern with an inclined thread. In one or more embodiments, the inner thread and the outer thread may include a helix-shaped thread pattern. In one or more embodiments, the inner thread or the outer thread may include one or more gaps in the thread pattern.
[0177] [0177] In one or more modalities, the internal surface of the projection can be essentially parallel to the external surface of the projection.
[0178] [0178] In one or more modalities, at least one disinfectant sponge is configured inside the second cavity (40, 140, 240).
[0179] [0179] In one or more embodiments, the lid may include a removable cover seal at the opening of the second cavity to seal the disinfectant sponge inside the second cavity before using the lid.
[0180] [0180] In one or more embodiments, the absorbent material 250 can be configured within the second cavity 240. As shown in Figures 49 and 50, the upper surface of the absorbent material 250 has a wavy opening that is contoured to accommodate a tip of a medical connector when positioned on the tip of a corresponding male or female medical connector. In one or more embodiments, the disinfectant or antimicrobial agent disinfects an outer surface and an inner surface of the needle-free female connector or needle-free male connector when the needle-free female connector or the needle-free male connector is inserted into the second cavity 240. In one or more modalities, as shown in Figure 43, the septum 262 can be attached to the open bottom of the insert adjacent to the wavy opening of the upper surface of the absorbent material 250, thus forming a seal to keep the disinfectant or antimicrobial agent inside the second cavity 240 before using cap 210. In one or more embodiments, the absorbent material 250 can be a foam or a sponge. In one embodiment, the foam may be a polyurethane foam. In one or more embodiments, the absorbent material 250 may include cracks. In one or more embodiments, a compression of the absorbent material 250 towards the upper wall of the enclosure occurs through connection to the needle-free female connector, whereby compression of the absorbent material disinfects the needle-free female connector. In one or more embodiments, the absorbent material 250 may be under radial compression by the internal thread on the internal surface of the projection with split thread to retain the absorbent material in the second cavity. In one or more embodiments, the absorbent material 250 is a closed cell foam sponge with roughness and surface geometry features that is effective in sealing the opening of the fluid path in the Luer IV connectors when a disinfectant cover 210 is applied. Sealing the connectors when a disinfectant cap is applied is a particular advantage for a disinfectant cap 210 because: 1) the sealing effect of the absorbent material and / or the septum limits the amount of disinfectant solution that enters the opening of the fluid path in a Luer IV connector; and 2) the sealing effect of the absorbent material and / or the septum limits the amount of fluid leakage in the luer connector and in the IV line to which it is connected, leaking, in the event that the clamp or valve of the intravenous line is left inadvertently in an open state, when a disinfectant cover is applied to the luer connector.
[0181] [0181] In one or more modalities, the female connector can be selected from the group consisting essentially of needle-free connectors, catheter luer connectors, taps and hemodialysis connectors. In one or more modalities, the needle-free connector is selected from a Q-Syte, MaxPlus, MaxPlus Clear, MaxZero, UltraSite, Caresite, InVision-Plus, Safeline, OneLink, V-Link, ClearLink, NeutraClear, Clave, MicroClave, MicroClave Clear, Neutron, NanoClave, Kendall, Nexus, InVision, Vadsite, Bionector, etc.
[0182] [0182] In one or more modalities, the male connector can be an end of an intravenous tube, a tap or a male luer lock.
[0183] [0183] In some embodiments, the connector comprises a needle-free injection site, which can sometimes be called a needle-free port, hub, valve or injection device, or as an access site, port, hub, valve or device without needle, which may include brands such as Clave® (available from ICU Medical, Inc.), SmartSite® (available from Cardinal Health, Inc.) and Q- In some embodiments, the cap can be attached to anyone various needle-free injection sites, such as those listed above. In one or more modalities, after the cap has been attached to the connector, it is not necessary to disinfect (for example, treat with an alcohol swab) the connector before each reconnection of the connector with another connector, as the connector will be kept in an environment uncontaminated state while attached to the cover. The use of the cover replaces the standard swab cleaning protocol for cleaning connectors.
[0184] [0184] A fourth aspect of this disclosure concerns a method of disinfecting a medical connector. The method comprises connecting the cover of one or more modalities to a medical connector, where the connection includes engaging the threads of the medical connector with the threads on the inner or outer surface of the second cavity of the cover after inserting the medical connector in the cover so that the medical connector contacts the absorbent material and the disinfectant or antimicrobial agent.
[0185] [0185] The exemplary covers (10, 110 and 210) of the present disclosure are capable of continuous disinfection of a connector and minimize the entry of microbial agents.
[0186] [0186] The disinfectant caps currently available on the market are capable of disinfecting only one of the three types of luer fittings, that is, female luer of needle-free connectors, female luer of taps and male luer connectors at intravenous injection sites. Thus, to avoid the need to use different types of disinfectant caps to clean different types of connectors, the exemplary caps (10, 110 and 210) are wrapped with male luer connectors and also with female luer connectors, allowing the user to clean different types of connectors with a single device. When mounting exemplary covers (10, 110 and 210) on female luer connectors, the female luer connectors are inserted into the second cavity (40, 140, 240) and screwed into the internal threads (36, 136, 236) of the exemplary covers (10, 110 and 210). When mounting the cover on a male luer connector, the male luer connector is inserted into the second cavity (40, 140, 240) and screwed into the external threads (38, 138, 238) of the example covers (10, 110 and 210). The absorbent material (50, 150, 250) and the disinfectant or antimicrobial agent contact the female luer connector after inserting the female luer connector in the second cavity (40, 140, 240) of the exemplary caps (10, 110 and 210). The absorbent material (50, 150, 250) and the disinfectant or antimicrobial agent come into contact with the male luer connector, the female luer connector and the hemodialysis connector after inserting the connector in the second cavity (40, 140, 240) of the exemplary lids (10, 110 and 210).
[0187] [0187] Therefore, the device of the present disclosure can be mounted on male and female luer connectors, thus meeting a current need in the technique.
[0188] [0188] A fifth aspect of the present disclosure concerns an assembly. The assembly comprises the cover of one or more modalities connected to a medical connector. In one or more modalities, the medical connector is selected from a male luer connector, a female luer connector and a needle-free connector.
