Fluid connector assembly

Abstract

The utility model discloses a fluid connector assembly. The fluid connector assembly seals a fluid path in a corresponding connector. When the connectors of the fluid connector assembly are connected to each other, respective compressible members in the connectors are displaced, allowing downstream fluid to pass through the fluid connector assembly. The connector remains connected by a snap mechanism that provides a threshold retention force. When an external force greater than a threshold force is applied to the fluid connector assembly, the snap mechanism may no longer hold the connectors together, thereby disengaging the connectors from each other. Once the connectors are disengaged, the connection mechanism may be activated to prevent the connectors from being coupled together without actuation of the connection mechanism.

Description

Technical Field

[0001] The present disclosure generally relates to medical fluid connectors, and more particularly, to a fluid connector assembly that includes medical connectors that disengage from each other due to an applied force, each medical connector being designed to automatically close their respective fluid paths. The disengagement may be due to an intentional or unintentional separation between the medical connectors. Background Art

[0002] Peripheral intravenous catheters ("PIVCs") are medical tools that are inserted into a patient's peripheral vein to deliver medical fluids to the patient. In one exemplary application, a medical fluid is delivered to the patient, and subsequently, a medical professional removes the PIVC catheter from the patient's body. However, these catheters are often unintentionally displaced. For example, a catheter line subjected to an unexpected or accidental pulling force may pull on the IV fitting, thereby pulling the catheter out of the patient's body. In other cases, the catheter is accidentally removed from the patient and the medical professional. Unintentional or accidental displacement may result in patient blood loss, IV fluid loss, and IV fluid delivery delays. Summary of the Utility Model

[0003] According to at least some embodiments disclosed herein, it is recognized that an unintentional displacement or disconnection of a medical connection, such as a medical fluid line, may cause harm to a patient or a medical professional, such as by depriving the patient of medication, increasing the likelihood of patient infection, and exposing the medical professional to medication.

[0004] Aspects of the present disclosure provide a fluid connector assembly having medical connectors, each medical connector including one or more fluid paths that respond to an unintentional or accidental external force by disengaging from each other and sealing their respective fluid paths. The disengagement may include an automatic disengagement using a bellows or other elastically compressible member that decompresses and returns to its original shape when the external force is no longer acting thereon. Advantageously, the fluid connector assemblies described herein may limit or prevent patient blood loss, IV fluid loss, infection, and medical delivery delays. Additionally, aspects of the present disclosure provide a connection mechanism that facilitates connection of the fluid connector assembly in the event of disengagement of the fluid connector assembly.

[0005] According to certain embodiments, the fluid connector assembly includes a first connector having a first end and a second end, a second connector configured to be coupled to the first connector, and a connection mechanism disposed on the first connector. The connection mechanism may include a first end and a second end opposite the first end. The second end of the connection mechanism may extend beyond the second end of the first connector. When the first connector and the second connector are disconnected, the connection mechanism may remain disposed on the first connector.

[0006] In some embodiments, the coupling mechanism is formed of an elastic material. In some embodiments, the coupling mechanism is slidable along the first connector and includes a deployed position and a retracted position. In the deployed position, the second end of the coupling mechanism may extend beyond the second end of the first connector such that the second end of the first connector is positioned within the internal chamber of the coupling mechanism. In the retracted position, the second end of the coupling mechanism may be positioned closer to the first end of the coupling mechanism such that the second end of the first connector is positioned outside of the internal chamber. In the retracted position, the second connector is capable of being coupled to the first connector. In the deployed position, when the first connector and the second connector are coupled, the first connector and the second connector may be disposed within the internal chamber of the coupling mechanism. When a threshold force is applied to one of the first connector and the second connector, the first connector and the second connector may become decoupled. When the first connector and the second connector become decoupled, the coupling mechanism may remain coupled to the first connector in the deployed position. When the first connector and the second connector become decoupled and the coupling mechanism is in the deployed position, the coupling mechanism may prevent the first connector and the second connector from being coupled.

[0007] According to certain embodiments, a method for operating a fluid connector assembly includes providing a first connector, a second connector, and a coupling mechanism. The first connector may have a first end and a second end. The second connector may be configured to be coupled to the first connector. The coupling mechanism may be disposed on the first connector and includes a first end and a second end opposite the first end. The method may further include positioning the coupling mechanism in the retracted position, coupling the first connector and the second connector, and positioning the coupling mechanism in the deployed position.

[0008] In some embodiments, positioning the coupling mechanism in the retracted position includes sliding the second end of the coupling mechanism along the first connector in a direction toward the first end such that the second end of the first connector is exposed.

[0009] In some embodiments, positioning the coupling mechanism in the deployed position includes sliding the coupling mechanism in the direction of the second end such that the coupling mechanism is disposed on the first connector and the second connector.

[0010] In some embodiments, when a threshold force is applied to one of the first connector and the second connector, the first connector and the second connector may become decoupled. When the first connector and the second connector become decoupled, the coupling mechanism may remain disposed on the first connector in the deployed position. The method may further include positioning the coupling mechanism in the retracted position such that the mating surface of the first connector may be disinfected.

[0011] According to certain embodiments, a fluid connector assembly includes a first connector, a second connector, and a connection mechanism. The first connector may include a first end and a second end opposite the first end. The second connector may include a first end and a second end opposite the first end, and may be configured to removably couple to the first connector. The connection mechanism may include a first end, a second end opposite the first end, and an internal chamber formed between the first end and the second end. The first connector may be disposed within the internal chamber. In a retracted position, the second end of the connection mechanism may be positioned closer to the first end of the connection mechanism such that the second end of the first connector is positioned outside the internal chamber. In an extended position, the second end of the connection mechanism may extend beyond the second end of the first connector such that the second end of the first connector is positioned within the internal chamber of the connection mechanism. When the connection mechanism is in the retracted position, the second connector is capable of coupling to the first connector. When the first connector and the second connector are coupled, the connection mechanism may return to the extended position. When the first connector and the second connector are decoupled, the connection mechanism may remain in the extended position.

[0012] In some embodiments, the connection mechanism may slide along the first connector between the retracted position and the extended position.

[0013] In some embodiments, in the retracted position, the second end of the connection mechanism may be positioned closer to the first end of the connection mechanism such that the second end of the first connector is positioned outside the internal chamber.

[0014] In some embodiments, when a threshold force is applied to one of the first connector and the second connector, the first connector and the second connector may be decoupled. When the first connector and the second connector are decoupled, the connection mechanism may remain coupled to the first connector in the extended position. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject technology. It should be understood that the subject technology may be practiced without these specific details. In other instances, well-known structures and techniques have not been shown in detail so as not to obscure the subject technology.

[0027] Furthermore, although this specification sets forth specific details of various embodiments, it should be understood that this specification is illustrative only and should not be construed in any way as restrictive. Additionally, it is contemplated that although specific embodiments of the present disclosure may be disclosed or shown in the context of an IV set, these embodiments may be used in other fluid delivery systems. Moreover, various applications of such embodiments and their modifications that may be contemplated by those skilled in the art are also included in the general concepts described herein.

[0028] According to some embodiments, the present disclosure includes various features and advantages of a fluid connector assembly having medical connectors that seal their respective fluid paths when the medical connectors are disengaged from each other. The medical connectors may each include a compressible member that decompresses in response to disengagement to provide an automatic seal of the respective fluid path. The fluid connector assembly may also include a connection mechanism that may serve to prevent a patient from reconnecting the fluid connector assembly such that the corresponding surfaces may be properly disinfected.

[0029] Referring now to the drawings, Figure 1 FIG. 1 shows an IV kit 1 coupled to a patient 10 in accordance with aspects of the present disclosure. The IV kit 1 includes a drug bag 12, a drip chamber 14, and tubing 22. The tubing 22 extends between the drip chamber 14 of the IV kit 1 and a fluid connector assembly 100. To prevent the tubing 16 or the catheter 18 from being accidentally displaced or disconnected from the patient, a tape 26 is placed over the tubing 16 and the catheter 18 such that the tape 26 engages the tubing 16, the catheter 18, and the patient 10.

[0030] Figure 2 FIG. 2 shows a perspective view of a fluid connector assembly 100 in accordance with aspects of the present disclosure. As a non-limiting example, the fluid connector assembly 100 is designed for medical applications such as the IV kit 1 (as Figure 1 shown) and other IV medical fluid delivery applications using catheters (including PIVC catheters).

[0031] As shown, the fluid connector assembly 100 includes a connector 102 and a connector 104 coupled to the connector 102. The connector 102 and the connector 104 may be referred to as a first connector and a second connector, respectively. However, "first" and "second" may be interchanged. Additionally, each of the connectors 102 and 104 may be referred to as a medical connector. When the connector 102 and the connector 104 are connected to each other, a fluid path for medical fluid is established through the fluid connector assembly 100.

[0032] In some embodiments, the connector 104 is connected to a medical fluid (not shown). Additionally, in some embodiments, the connector 102 is connected to a catheter line (not shown) that delivers the medical fluid to a catheter. In this regard, the connector 104 may include a fluid inlet 106 that serves as a fluid receiving location of the fluid connector assembly 100. Additionally, the connector 102 may include a fluid outlet 108 that serves as a fluid transmission location of the fluid connector assembly 100.

[0033] To facilitate connection to the medical fluid, the connector 104 may include a luer fitting 110. In some embodiments, the luer fitting 110 is a female luer fitting designed to mate with a male luer fitting connected to the medical fluid. Similarly, to facilitate connection to the catheter line, the connector 102 may include a luer fitting 112. In some embodiments, the luer fitting 112 is a male luer fitting designed to mate with a female luer fitting connected to the catheter line. Each of the luer fittings 110, 112 may comply with standards established by the International Organization for Standardization ("ISO") to enhance patient safety, minimize leakage of medical fluid, and reduce misconnections with other connecting devices.

[0034] In addition, the connector 102 may include a strut 128 that passes through the connector 102 centrally or at least approximately centrally. The strut 128 may include a passage 130 that establishes a fluid outlet 108. Although the strut 128 is illustrated as cylindrical, the strut 128 need not be so limited and may have any suitable shape.

[0035] Reference Figure 3 , the connector 102 may include a housing 114 integral with the luer 112. The housing 114 may include a first end 114A having an integral luer 112 and a second end 114B opposite the first end 114A, the second end being configured to be coupled to the receiving ring 134. The second end 114B of the housing 114 may have a stepped profile where the thickness of the protruding portion 120 is reduced relative to the thickness of the remainder of the housing. The second end 114B of the housing 114 may include an inner diameter 154.

[0036] The housing 114 may include an outer surface 116 and an inner surface 118. The housing 114 may include a hollow or substantially hollow body that houses one or more components. For example, in addition to the strut 128, a compressible member 146, which will be discussed in more detail, may be housed within the housing 114. The housing 114 may also include a wall 122 that extends transversely through the interior of the connector 102, thereby dividing the interior of the connector 102 into separate cavities 124, 126. The strut 128 may be integrally formed with the wall 122 and extend through each cavity 124, 126. The strut 128 may include an open first end 128A, a closed second end 128B opposite the first end 128A, and a passage 130 that extends through the strut 128. The first end 128A may include an opening for the passage 130 that forms the fluid outlet 108. The second end 128B of the strut 128 may be a substantially closed end and include one or more holes, also referred to as flow windows or openings 132. The openings 132 may be fluidly connected to the passage 130 and the fluid outlet 108.

[0037] The connector 102 may also include a receiving ring 134 disposed at and coupled to the second end 114B of the housing 114. The receiving ring 134 may include a first end 134A configured to be coupled to the second end 114B and a second end 134B opposite the first end 134A. The first end 134A of the receiving ring 134 may have a stepped profile that has a protruding portion 136 complementary to the protruding portion 120 of the housing. The second end 134B of the receiving ring 134 may include an opening 138. The receiving ring 134 may have an outer surface 140 and an inner surface 142. The receiving ring 134 may include one or more notches 144 formed along the outer surface 140. In some embodiments, as Figure 3As shown, the receiving ring 134 is coupled to the housing 114 of the connector 102. In other embodiments, the receiving ring 134 may be integrally formed with the housing 114 of the second connector 102, thereby forming a monolithic structure.

[0038] As described above, the connector 102 may include a compressible member 146 disposed inside the housing 114, also referred to as a silicone valve. The compressible member 146 may be disposed within a cavity 126 of the housing 114 and extend through the receiving ring 134. The compressible member 146 may have a first end 146A and a second end 146B, the first end being positioned adjacent the surface of the wall 122 and the second end being positioned within an opening 138 of the receiving ring 134 and configured to engage a component of the connector 104. The second end 146B may include an engagement surface 148. The engagement surface 148 may provide a flat or substantially flat surface that may be readily accessible for cleaning and disinfection. The engagement surface 148 may further include an opening 150. In some embodiments, the opening 150 may be formed as one or more slits or holes. The strut 128 may extend through the compressible member 146. In other words, the compressible member 146 may extend around the outer surface of the strut 128. The second end 128B of the strut 128 may be positioned within a region formed adjacent the second end 146B of the compressible member 146.

[0039] In some embodiments, the compressible member 146 includes a bellows that is capable of being elastically compressed. Thus, the compressible member 146 may be compressed by an external force and subsequently return to its original uncompressed form when the external force is removed. The compressible member 146 may be designed to regulate fluid flow through the connector 102.

[0040] Figure 4 A perspective view of a connection device 104 in accordance with aspects of the present disclosure is shown, with additional features illustrated. The connector 104 may include a housing 156. The housing 114 (as Figure 3 shown) and the housing 156 may be referred to as a first housing and a second housing, respectively. However, "first" and "second" may be interchanged. As shown, the housing 156 may be integral with the luer 110.

[0041] The housing 156 may include a first end 156A and a second end 156B opposite the first end 156A, the first end being configured to mate with the connector 102 when coupled. The housing 156 may include an outer surface 158 and an inner surface 160. The housing 156 may include a channel 168 extending through the interior of the housing 156. The housing 156 may include a hollow or substantially hollow body that houses one or more components. For example, the housing 156 may include a compressible member 178 located within or at least substantially within the housing 156.

[0042] The outer diameter 190 can include dimensions that allow at least a portion of the compressible member 178 and at least a portion of the housing 156 to enter the connector 102 (as Figure 5 shown). In this way, the inner diameter 154 of the second end 114B ( Figure 4 shown) can be sized larger than the outer diameter 190 of the first end 156A of the housing 156, thereby allowing the first end 156A of the connector 104 to be inserted into the second end 114B of the connector 102.

[0043] The connector 104 can include a forward portion 162 formed within the housing 156 at the first end 156A for receiving the compressible member 178. The housing 156 at the first end 156A can include an inwardly extending edge 164, thereby forming one end of the forward portion 162. The inwardly extending edge 164 can surround an opening 166 at the first end 156A of the housing 156. The outer surface of the inwardly extending edge 164 can be designed to engage the mating surface 148.

[0044] The connector 104 can also include a collar member 170 that extends circumferentially around the outer surface 158. The collar member 170 can include a first end 170A, a second end 170B disposed opposite the first end 170A, an outer surface 170C, and an inner surface 170D. The collar member 170 can also include one or more slits 172 that extend longitudinally along the collar member 170. When connecting the connectors 102, 104, the slits 172 can allow the collar member 170 to bend. The second connector 104 can also include a gap 174 formed between the outer surface 158 of the connector 104 and the inner surface 170D of the collar member 170. The diameter of the collar member 170 can be sized to accommodate the second end 134B of the receiving ring 134.

[0045] As Figure 5 shown, when connecting the connectors 102, 104, the second end 134B of the receiving ring 134 can be disposed within the gap 174 such that the inner surface 170D is disposed on the outer surface 142 of the receiving ring 134. During the connection of the connectors 102, 104, the collar member 170 can bend outward via the slits 172 such that the size of the gap 174 increases, thereby allowing the insertion of the receiving ring 134. Once the connectors 102, 104 are connected, the collar 170 can return to its initial position such that the second end 170B is disposed within the notch 144 of the receiving ring 134, thereby forming a retaining force between the connectors 102, 104.

[0046] However, when an external force (such as a pulling force applied to one or more of connectors 102 and 104) is applied to at least one of connectors 102 and 104 and is greater than a threshold force, the collar member 170 may no longer maintain the connection / linkage between connectors 102 and 104, and connectors 102 and 104 may become disengaged from each other. When this occurs, the forward portion 162 of connector 104 and the housing 156 can be removed from the housing 114 of connector 102.

[0047] Connector 104 may further include a compressible member disposed within housing 156, also referred to as resilient plug 178. In particular, compressible member 178 may be disposed within forward portion 162. Compressible member 178 may include a first end 178A positioned within opening 166 and a second end 178B opposite first end 178A. First end 178A may include a mating surface 180. First end 178A may extend from the forward portion 162 of housing 156 such that mating surface 180 is positioned in front of the inwardly extending edge 164. In other words, when connectors 102, 104 are disconnected, mating surface 180 may form the outer surface of housing 156. This positioning may allow mating surface 180 to be easily accessible for cleaning and disinfection. Mating surface 180 may include one or more holes 182.

[0048] Compressible member 178 may further include an opening 184 formed at second end 178B. Although Figure 4 a single opening formed in compressible member 178 is shown, the number of openings may vary. For example, in some embodiments, one or more openings may be formed in compressible member 178. In either case, each opening may include any of the features shown and described for opening 184. Fluid flowing through fluid inlet 106 may pass through compressible member 178 via holes 182. In some embodiments, compressible member 178 includes a bellows that is capable of being elastically compressed. Thus, compressible member 178 may be compressed by an external force and subsequently return to its original uncompressed form when the external force is removed. Compressible member 178 may be designed to regulate fluid flow through connector 104.

[0049] Based on this connection, a seal may be formed between housing 156 and compressible member 178 such that when connector 104 is disconnected from connector 102, fluid does not flow between housing 156 and compressible member 178.

[0050] Based Figure 4 on the position of compressible member 178 shown, connector 104 may prevent fluid from flowing through. In other words, due to the positioning and expanded state of compressible member 178, fluid entering channel 168 via fluid inlet 106 may be prevented from passing through forward portion 162.

[0051] To facilitate fluid passage through connectors 102, 104, when assembling the fluid connector assembly 100, the respective compressible members 146, 178 can be actuated or displaced to expose corresponding openings in connectors 102, 104.

[0052] Figure 5 A partial cross-sectional view of the fluid connector assembly 100 in accordance with aspects of the present disclosure is shown, showing the engaged connectors 102 and 104, and also showing the actuation of the compressible members 146 and 178. The fluid connector assembly 100 can be assembled by coupling the connectors 102, 104. To couple the connectors 102, 104, the respective mating surfaces 148, 180 can be positioned such that they contact each other. Due to the respective dimensions of the inner diameter 154 of connector 102 and the outer diameter 190 of connector 104, connector 104 can be received within the opening 138 of the receiving ring 134. Then, a force or pressure can be applied to one or both of the connectors 102, 104. When pressure is applied, the compressible members 146, 178 can begin to deform. For example, the compressible member 146 can deform such that the second end 146B of the compressible member 146 moves in a direction toward the first end 146A, thereby positioning the second end 146B within the cavity of the receiving ring 134. When the compressible member 146 deforms under pressure, the second end 128B of the strut 128 can project through the opening 150 of the mating surface 148. The second end 146B of the compressible member 146 can continue to deform until the opening 132 of the strut 128 is exposed, thereby allowing fluid to enter the channel 130 of the strut 128. Similarly, when pressure is applied to one or both of the connectors 102, 104, the first end 156A of connector 104 can move within the receiving ring 134, and the compressible member 178 can deform such that the first end 178A of the compressible member 178 moves toward the second end 178B within the forward portion 162. As connector 104 moves within the housing 114 of connector 102, the second end 128B of the strut 128 can contact the mating surface 180 of the compressible member 178. In some embodiments, the strut 128 can extend through the hole 182 of the mating surface 180.

[0053] The forward portion 162 of connector 104 can be inserted into the receiving ring 134 and the housing 114, and can be at least partially inserted into the cavity 126 of the housing 114. The connectors 102, 104 can be held together via the interconnection of the collar member 170 and the notch 144. In particular, the connectors 102, 104 can be held together via a friction fit or an interference fit between the collar member 170 and the notch 144.

[0054] When inserting the housing 156, the forward portion 162 can engage the compressible member 146 of the connector 102. For example, as Figure 5 shown, the compressible member 146 of the connector 102 can engage the compressible member 178 of the connector 104 such that the engagement surface 148 of the compressible member 146 contacts the engagement surface 180 of the compressible member 178. From the perspective of the compressible member 146, the external force can be provided by at least the forward portion 162 and / or the engagement surface 180. Thus, based on the above insertion and engagement, the engagement surface 180 and / or the forward portion 162 can provide a force to actuate the compressible member 146.

[0055] For example, the actuation of the compressible member 146 can include compression of the compressible member 146. In this way, the compression of the compressible member 146 can cause the compressible member 146 to decrease in size to move relative to the strut 128, thereby exposing the opening 132 of the strut 128. Thus, the opening 132 of the strut 128 can be uncovered by the compressible member 146 such that the compressible member 146 no longer provides a seal against fluid entry into the opening 132. In this manner, the compressible member 146 located in the housing 114 can be designed to be actuated, e.g., compressed, in response to a force received by an external object of the connector 104.

[0056] In some embodiments, the strut 128 of the connector 102 can engage the compressible member 146 of the connector 102 simultaneously or near-simultaneously with the insertion of the forward portion 162 and the housing 156 into the housing 114. For example, the second end 128B of the strut 128 can pass through the opening 150 to engage the engagement surface 180 of the compressible member 178. From the perspective of the compressible member 178, the external force can be provided by at least the strut 128. As the forward portion 162 and the housing 156 are further inserted into the housing 114, the strut 128 can provide a force to actuate the compressible member 178. For example, the actuation of the compressible member 178 can include compression of the compressible member 178, thereby reducing the size of the compressible member 178 and forcing the first end 178A of the compressible member 178 out of the opening 166 of the forward portion, thereby breaking the seal between the compressible member 178 and the first end 156A of the connector 104. In addition, the actuation of the compressible member 178 can allow the strut 128 to pass through the opening 166 of the housing 156 and extend into the interior of the housing 156 at the forward portion 162. Further, the strut 128 can pass through the opening 166 such that the opening 132 of the strut 128 can also pass through the opening 166 and be positioned inside the housing 156. Thus, the compressible member 178 located in the housing 156 can be designed to be actuated, i.e., compressed, in response to a force received by an external object of the connector 102.

[0057] Based on the construction of the fluid connector assembly 100, a fluid path can be established. Thus, fluids, including medical fluids, can flow downstream from connector 104 through the fluid connector assembly 100 to connector 102. As shown, the fluid can enter the fluid inlet 106 of the housing 156 and then pass through the compressible member 178 via the opening 184 of the compressible member 178. Then, the fluid can pass through the opening 132 of the strut 128 and then through the channel 130 of the strut 128. The fluid can flow out of the fluid connector assembly 100 through the fluid outlet 108 of the housing 114.

[0058] As described above, the detachment of connectors 102 and 104 can be caused by an external force applied to one or more of connectors 102 and 104, where the external force exceeds the threshold force provided by the collar member 170 that maintains the connection between connectors 102 and 104.

[0059] When connectors 102, 104 are detached, the forces applied to the compressible members 146, 178 of connectors 102, 104, respectively, can be removed, such that the compressible members 146, 178 can decompress and expand, causing the compressible members 146, 178 to return to their original shapes. For example, during the expansion of the compressible member 146, the second end 146B of the compressible member 146 can move towards the second end 134B of the receiving ring 134 until the compressible member 146 has returned to its original shape, such that the second end 146B is positioned within the opening 138 of the receiving ring 134. Similarly, during the expansion of the compressible member 178, the first end 178A can move towards the opening 166 until the compressible member 178 has returned to its initial shape, such that the first end 178A is positioned within the opening 166. As a result, fluid may not be able to flow upstream through connector 102 and through the opening 132 of the strut 128.

[0060] Each of the compressible members 146 and 178 can act as a valve to regulate the fluid passing through the fluid connector assembly 100. Based on their elastic, spring-like properties, each of the compressible members 146 and 178 can automatically return to their respective shapes when the external force no longer acts on them. Advantageously, the compressible members 146 and 178 can rebound in response to the detachment between connectors 102 and 104 to provide a relatively quick sealing effect. Thus, when integrating the fluid connector assembly 100 into an IV set and catheter, blood loss, IV fluid loss, and drug delivery delays can be restricted or prevented based on one or more properties of the compressible members 146 and 178.

[0061] In some embodiments, the fluid connector assembly 100 can further include a connection mechanism 200 that activates when the fluid connector assembly 100 is detached.

[0062] Refer to FIG. 6- Figure 10 , the connecting mechanism 200 (also referred to as a sleeve) may include a body 202 having a first end 202A, a second end 202B opposite the first end, an outer surface 202C, and an inner surface 202D. The inner surface 202D may define an internal chamber 204 within the body 202 of the connecting mechanism 200. When assembled, the connector 102 may be disposed within the internal chamber 204 of the connecting mechanism 200 such that the inner surface 202D of the body 202 is disposed on the outer surface 116 of the connector 102. Additionally, the body 202 may be slidably coupled to the connector 102 such that the body 202 is capable of sliding along the longitudinal axis of the connector 102. In some embodiments, the body 202 further includes an exposed portion or window 206 to allow a user to view the contents of the connector 102. Additionally, the exposed portion 206 may also allow the body 202 to deflect during movement to a retracted position.

[0063] In some embodiments, the connecting mechanism 200 is formed of an elastic material. However, the connecting mechanism 200 need not be so limited and may be formed of any suitable material capable of deforming and having elastic properties.

[0064] As shown in FIG. 6- Figure 10 shown, the connecting mechanism 200 may include a deployed position and a retracted position. As Figure 7 shown, in the deployed position, the body 202 may be disposed on the connector 102 such that the first end 202A of the body 202 is positioned adjacent to the first end 114A of the connector 102 and the second end 202B of the body 202 extends beyond the second end 114B of the connector 102 and the receiving ring 134 such that the second end 114B and the receiving ring 134 are disposed within the internal chamber 204. Since the second end 114B of the connector 102 is disposed within the internal chamber 204, the body 202 may completely surround the engagement surface 148 of the connector 102, thereby helping to prevent undesired contamination of the engagement surface 148 when the connectors 102, 104 are not coupled. Additionally, in the deployed position, the user may be prevented from coupling the connectors 102, 104 until the connecting mechanism 200 is actuated.

[0065] Refer to Figure 8 , in the retracted position, the second end 202B of the body 202 may be positioned closer to the first end 202A of the body 202 such that the second end 114B of the connector 102 and / or the receiving ring 134 are positioned outside of the internal chamber 204. Thus, the retracted position may allow the engagement surface 148 to be exposed. When the connecting mechanism 200 is in the retracted position, the user is able to couple the connectors 102, 104.

[0066] Figures 6A - 6D The operation of the connection mechanism 200 is shown. In some embodiments, the connection mechanism 200 can be actuated by a user to move between a deployed position and a retracted position. For example, the user can grasp a portion of the body 202 and slide the body 202 relative to the connector 102 in the direction of the first end 114A of the connector 102. Accordingly, the second end 202B of the body 202 can move in the direction of the first end 202A of the body 202, thereby exposing the second end 114B of the connector 102 and / or the receiving ring 134. Since the connection mechanism 200 is in the retracted position, the user can couple the connectors 102, 104 via the above process such that the connectors 102, 104 are connected as Figure 9 shown.

[0067] Then, the user can actuate the connection mechanism 200 to return the connection mechanism 200 to the deployed position, as Figure 10 shown. For example, the user can grasp the body 202 and slide the body 202 towards the second end 114B of the connector 202 such that the body 202 slides longitudinally along the connector 102. The body 202 can continue to slide in the direction of the second end 114B until the second end 114B of the connector 102 and the connector 104 are positioned within the internal chamber 204. In the case where the connectors 102, 104 are coupled and the connection mechanism 200 is in the deployed position, the connection mechanism 200 can further help prevent undesired disconnection of the connectors 102, 104.

[0068] As described above, when an external force exceeding a threshold force is applied to one or both of the connectors 102, 104, the connectors 102, 104 can become disengaged. In the case where the connectors 102, 104 become disengaged, the connection mechanism 200 can remain in the deployed position and be disposed on the connector 102. Thus, after the connectors 102, 104 become disengaged, the second end 114B and the engagement surface 148 can remain disposed within the internal chamber 204 of the connection mechanism 200. In other words, during a disconnection event, the connection mechanism 200 can help isolate the connectors 102, 104 to prevent reconnection before the engagement surface 148 is disinfected. Once disconnected, the user can actuate the connection mechanism 200 to the retracted position to allow the engagement surface 148 to be disinfected before reconnecting the connectors 102, 104.

[0069] Features of the present disclosure provide a first compressible member and a second compressible member, which can be used as valves to regulate the fluid passage therebetween. The first compressible member and the second compressible member are respectively located in a first connector and a second connector. If the first connector and the second connector are separated, whether inadvertently or intentionally, the fluid passages for each of the first compressible member and the second compressible member are closed or blocked to prevent fluid loss therefrom. Features of the present disclosure also provide that when the first compressible member and the second compressible member are separated, either the first compressible member or the second compressible member can be cleaned and disinfected, and the first compressible member and the second compressible member can be re-coupled together to form a fluid passage therebetween.
