Fluid connector assembly and method of operating fluid connector assembly

Abstract

Disclosed herein are fluid connector assemblies and methods of operating fluid connector assemblies that seal fluid paths in respective connectors. 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 relates generally to medical fluid connectors, and more particularly to a fluid connector assembly including medical connectors that disengage from one another due to an applied force, each medical connector being designed to automatically close their respective fluid paths. The disengagement may be due to intentional or unintentional separation between the medical connectors. Background Art

[0002] A peripheral intravenous ("PIVC") catheter is a medical tool that is inserted into a patient's peripheral vein to deliver medical fluids to the patient. In one exemplary application, the medical fluid is delivered to the patient, and the PIVC catheter is subsequently removed from the patient by a medical professional. However, these catheters are often displaced unintentionally. For example, catheter lines that are subjected to unintended or accidental tension may pull on the IV tubing, thereby pulling the catheter out of the patient. In other cases, the catheter is accidentally removed from the patient and the medical professional. Unintentional or accidental displacement may result in blood loss to the patient, loss of IV fluid, and delays in IV fluid delivery. Summary of the invention

[0003] In accordance with at least some embodiments disclosed herein, it is recognized that inadvertent displacement or disconnection of a medical connection, such as a medical fluid line, may result in harm to a patient or medical professional, such as by depriving the patient of medication, increasing the likelihood of infection for the patient, and exposing the medical professional to drugs.

[0004] Aspects of the present disclosure provide a fluid connector assembly with a medical connector, each of which includes one or more fluid paths that respond to unintentional or unexpected external forces by disengaging from each other and sealing their corresponding fluid paths. Disengagement can include automatic disengagement using a bellows or other elastically compressible member that decompresses and returns to its original shape when an external force no longer acts thereon. Beneficially, the fluid connector assembly described herein can limit or prevent patient blood loss, IV fluid loss, infection, and medical delivery delays. In addition, aspects of the present disclosure provide a connecting mechanism that facilitates the connection of the fluid connector assembly when the fluid connector assembly is disengaged.

[0005] According to some embodiments, a 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 to 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 connecting mechanism is formed by an elastic material. In some embodiments, the connecting mechanism can slide along the first connector and includes an extended position and a retracted position. In the extended position, the second end of the connecting mechanism can extend beyond the second end of the first connector so that the second end of the first connector is positioned in the internal chamber of the connecting mechanism. In the retracted position, the second end of the connecting mechanism can be positioned closer to the first end of the connecting mechanism so that the second end of the first connector is positioned outside the internal chamber. In the retracted position, the second connector can be connected to the first connector. In the extended position, when the first connector and the second connector are connected, the first connector and the second connector can be arranged in the internal chamber of the connecting mechanism. When the threshold force is applied to one of the first connector and the second connector, the first connector and the second connector can be disengaged. When the first connector and the second connector are disengaged, the connecting mechanism can remain connected to the first connector in the extended position. When the first connector and the second connector are disengaged and the connecting mechanism is in the extended position, the connecting mechanism can prevent the first connector and the second connector from being connected.

[0007] According to certain embodiments, a method for operating a fluid connector assembly includes providing a first connector, a second connector, and a connecting 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 connecting mechanism may be disposed on the first connector and include a first end and a second end opposite to the first end. The method may also include positioning the connecting mechanism in a retracted position, connecting the first connector and the second connector, and positioning the connecting mechanism in an extended position.

[0008] In some embodiments, positioning the connecting mechanism in the retracted position includes sliding the second end of the connecting 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 connection mechanism in the deployed position includes sliding the connection mechanism in the direction of the second end such that the connection mechanism is disposed over 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 can be disengaged. When the first connector and the second connector are disengaged, the connection mechanism can remain disposed on the first connector in the deployed position. The method can also include positioning the connection mechanism in a retracted position so that the engagement surface of the first connector can be sterilized.

[0011] According to certain embodiments, the fluid connector assembly includes a first connector, a second connector and a connecting mechanism. The first connector may include a first end and a second end opposite to the first end. The second connector may include a first end and a second end opposite to the first end, and may be configured to be removably coupled to the first connector. The connecting mechanism may include a first end, a second end opposite to the first end, and an internal chamber formed between the first end and the second end. The first connector may be disposed in the internal chamber. In the retracted position, the second end of the connecting mechanism may be positioned closer to the first end of the connecting mechanism so that the second end of the first connector is positioned outside the internal chamber. In the deployed position, the second end of the connecting mechanism may extend beyond the second end of the first connector so that the second end of the first connector is positioned in the internal chamber of the connecting mechanism. When the connecting mechanism is in the retracted position, the second connector can be coupled to the first connector. When the first connector and the second connector are coupled, the connecting mechanism may return to the deployed position. When the first connector and the second connector are disengaged, the connecting mechanism may remain in the deployed position.

[0012] In some embodiments, the connection mechanism is slidable along the first connector between a retracted position and a deployed position.

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

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

[0026] In the following detailed description, many specific details are set forth in order to provide a full understanding of the subject technology. It should be understood that the subject technology can be practiced without these specific details. In other cases, well-known structures and techniques are not shown in detail to avoid confusing the subject technology.

[0027] Furthermore, although the present specification sets forth specific details of various embodiments, it should be understood that the description is illustrative only and should not be construed as limiting in any way. Furthermore, it is contemplated that although specific embodiments of the present disclosure may be disclosed or illustrated in the context of an IV set, these embodiments may be used in other fluid delivery systems. Furthermore, various applications of such embodiments and modifications thereof that may occur to a person 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 a medical connector that seals their respective fluid paths when the medical connectors are disengaged from each other. The medical connectors can each include a compressible member that decompresses in response to disengagement, thereby providing automatic sealing of the respective fluid paths. The fluid connector assembly can also include a connection mechanism that can function to prevent a patient from reconnecting the fluid connector assembly so that the respective surfaces can be properly disinfected.

[0029] Now referring to the accompanying drawings, Figure 1An IV set 1 coupled to a patient 10 is shown in accordance with aspects of the present disclosure. The IV set 1 includes a medication bag 12, a drip chamber 14, and tubing 22. The tubing 22 extends between the drip chamber 14 and the fluid connector assembly 100 of the IV set 1. To prevent the tubing 16 or catheter 18 from being accidentally removed or disconnected from the patient, a tape 26 is placed over the tubing 16 and catheter 18 such that the tape 26 engages the tubing 16, catheter 18, and the patient 10.

[0030] Figure 2 1 shows a perspective view of a fluid connector assembly 100 according to various aspects of the present disclosure. As a non-limiting example, the fluid connector assembly 100 is designed for medical applications, such as an IV set 1 (e.g., Figure 1 shown) and other IV medical fluid delivery applications using catheters (including PIVC catheters).

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

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

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

[0034] Additionally, connector 102 may include a post 128 centrally or at least approximately centrally extending through connector 102. Post 128 may include a passage 130 that establishes fluid outlet 108. While post 128 is illustrated as being cylindrical, post 128 need not be so limited and may have any suitable shape.

[0035] refer to Figure 3 , the connector 102 may include a housing 114 integral with a 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 couple to a receiving ring 134. The second end 114B of the housing 114 may have a stepped profile, wherein 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 carries one or more components. For example, in addition to the pillar 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 separating the interior of the connector 102 into separate cavities 124, 126. The pillar 128 may be integrally formed with the wall 122 and extend through each cavity 124, 126. The pillar 128 may include an open first end 128A, a closed second end portion 128B opposite the first end 128A, and a channel 130 extending through the pillar 128. The first end 128A may include an opening for the channel 130, which forms the fluid outlet 108. The second end 128B of the pillar 128 may be a substantially closed end and include one or more holes, also referred to as flow windows or openings 132. The opening 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 having a protrusion 136 that is complementary to the protrusion 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 shown in FIG. 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 to form a unitary structure.

[0038] As described above, the connector 102 may include a compressible member 146, also referred to as a silicone valve, disposed within the housing 114. The compressible member 146 may be disposed within the 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 proximate to the surface of the wall 122, and the second end being positioned within the 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 easily 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 pillar 128 may extend through the compressible member 146. In other words, the compressible member 146 may extend around the outer surface of the pillar 128. The second end 128B of the strut 128 may be positioned within a region formed proximate to the second end 146B of the compressible member 146 .

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

[0040] Figure 4 1 shows a perspective view of a connector 104 according to aspects of the present disclosure, wherein additional features are shown. The connector 104 may include a housing 156. The housing 114 (eg, Figure 3 As shown in the figure, the housing 156 and the housing 156 can be referred to as the first housing and the second housing, respectively. However, the "first" and "second" can be interchangeable. As shown in the figure, the housing 156 can be integrated with the Luer piece 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 passage 168 extending through the interior of the housing 156. The housing 156 may include a hollow or substantially hollow body that carries one or more components. For example, the housing 156 may include a compressible member 178 located or at least substantially located in the housing 156.

[0042] The outer diameter 190 may include a portion that allows at least a portion of the compressible member 178 and at least a portion of the housing 156 to enter the connector 102 (eg, Figure 5 In this way, the second end portion 114B ( Figure 4 The inner diameter 154 of the housing 156 (as shown) may be sized to be 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 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. An outer surface of the inwardly extending edge 164 can be designed to engage with the engagement surface 148.

[0044] The connector 104 may also include a collar member 170 extending circumferentially around the outer surface 158. The collar member 170 may 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 may also include one or more slits 172 extending longitudinally along the collar member 170. The slits 172 may allow the collar member 170 to bend when the connectors 102, 104 are connected. The second connector 104 may 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 may be sized to accommodate the second end 134B of the receiving ring 134.

[0045] like Figure 5 As shown, when the connectors 102, 104 are coupled, 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 coupling of the connectors 102, 104, the collar member 170 can bend outwardly via the slit 172 such that the size of the gap 174 increases, thereby allowing insertion of the receiving ring 134. Once the connectors 102, 104 are coupled, the collar 170 can return to its initial position such that the second end 170B is disposed within the recess 144 of the receiving ring 134, thereby forming a retention force between the connectors 102, 104.

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

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

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

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

[0050] based on Figure 4 The position of the compressible member 178 shown, the connector 104 can prevent fluid flow. In other words, due to the positioning and expansion state of the compressible member 178, the fluid entering the channel 168 via the fluid inlet 106 can be blocked from passing through the forward portion 162.

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

[0052] Figure 5 A partial cross-sectional view of a fluid connector assembly 100 according to various 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. In order to couple the connectors 102, 104, the corresponding engagement surfaces 148, 180 can be positioned so that they contact each other. Due to the corresponding sizes of the inner diameter 154 of the connector 102 and the outer diameter 190 of the connector 104, the connector 104 can be received in 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 the pressure is applied, the compressible members 146, 178 can begin to deform. For example, the compressible member 146 can be deformed so 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 in the cavity of the receiving ring 134. When the compressible member 146 deforms under pressure, the second end 128B of the strut 128 can extend through the opening 150 of the engagement 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 the connector 104 can move within the receiving ring 134, and the compressible member 178 can deform so that the first end 178A of the compressible member 178 moves toward the second end 178B within the forward portion 162. As the connector 104 moves within the housing 114 of the connector 102, the second end 128B of the strut 128 can contact the engagement surface 180 of the compressible member 178. In some embodiments, the strut 128 can extend through the hole 182 of the engagement surface 180.

[0053] The forward portion 162 of the 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 coupled together via the interconnection of the collar member 170 and the recess 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 recess 144.

[0054] When inserted into the housing 156, the forward portion 162 can engage the compressible member 146 of the connector 102. For example, Figure 5 As 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. Therefore, based on the above-mentioned 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, actuation of the compressible member 146 may include compression of the compressible member 146. In this manner, compression of the compressible member 146 may cause the compressible member 146 to decrease in size to move relative to the post 128, thereby exposing the opening 132 of the post 128. As a result, the opening 132 of the post 128 may not be covered by the compressible member 146, such that the compressible member 146 no longer provides a seal against fluid entering the opening 132. In this way, the compressible member 146 located in the housing 114 may be designed to actuate, such as to compress, in response to a force received by an object external to the connector 104.

[0056] In some embodiments, the post 128 of the connector 102 can engage the compressible member 146 of the connector 102 at or near the same time as the forward portion 162 and the housing 156 are inserted into the housing 114. For example, the second end 128B of the post 128 can engage the engagement surface 180 of the compressible member 178 through the opening 150. From the perspective of the compressible member 178, the external force can be provided by at least the post 128. As the forward portion 162 and the housing 156 are further inserted into the housing 114, the post 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, forcing the first end 178A of the compressible member 178 to leave 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. Additionally, actuation of the compressible member 178 can allow the post 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. Additionally, the post 128 can pass through the opening 166 so that the opening 132 of the post 128 can also pass through the opening 166 and be positioned within the interior of the housing 156. Thus, the compressible member 178 located in the housing 156 can be designed to actuate, i.e., compress, in response to a force received by an object external to the connector 102.

[0057] Based on the configuration of the fluid connector assembly 100, a fluid path can be established. Thus, fluids, including medical fluids, can pass from the connector 104 downstream through the fluid connector assembly 100 to the 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. The fluid can then pass through the opening 132 of the support 128 and then through the channel 130 of the support 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, disengagement of the connectors 102 and 104 may be caused by an external force applied to one or more of the connectors 102 and 104 , where the external force exceeds a threshold force provided by the collar member 170 that maintains the connection between the connectors 102 and 104 .

[0059] When the connectors 102, 104 are disengaged, the forces applied to the compressible members 146, 178 of the connectors 102, 104, respectively, can be removed so that the compressible members 146, 178 can decompress and expand so that the compressible members 146, 178 return to their original shapes. For example, during expansion of the compressible member 146, the second end 146B of the compressible member 146 can move toward the second end 134B of the receiving ring 134 until the compressible member 146 has returned to its original shape so that the second end 146B is positioned within the opening 138 of the receiving ring 134. Similarly, during expansion of the compressible member 178, the first end 178A can move toward the opening 166 until the compressible member 178 has returned to its original shape so that the first end 178A is positioned within the opening 166. As a result, fluid may be unable to flow from upstream through the connector 102 and through the opening 132 of the strut 128.

[0060] Each of the compressible members 146 and 178 can be used as a valve to regulate the flow of fluid 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 external forces are no longer acting on them. Advantageously, the compressible members 146 and 178 can rebound in response to the disengagement between the connectors 102 and 104 to provide a relatively rapid sealing effect. Therefore, when the fluid connector assembly 100 is integrated into an IV set and catheter, blood loss, IV fluid loss, and drug delivery delays can be limited or prevented based on one or more characteristics of the compressible members 146 and 178.

[0061] In some embodiments, the fluid connector assembly 100 may further include a connection mechanism 200 that is activated when the fluid connector assembly 100 is disengaged.

[0062] Refer to Figure 6- Fig.10 , the connection mechanism 200 (also referred to as a sleeve) can 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 can form an internal chamber 204 within the body 202 of the connection mechanism 200. When assembled, the connector 102 can be disposed in the internal chamber 204 of the connection mechanism 200 so that the inner surface 202D of the body 202 is disposed on the outer surface 116 of the connector 102. In addition, the body 202 can be slidably coupled to the connector 102 so that the body 202 can slide along the longitudinal axis of the connector 102. In some embodiments, the body 202 also includes an exposed portion or window 206, thereby allowing a user to observe the contents of the connector 102. In addition, the exposed portion 206 can also allow the body 202 to deflect during movement to the retracted position.

[0063] In some embodiments, the connection mechanism 200 is formed of an elastic material. However, the connection mechanism 200 need not be so limited and may be formed of any suitable material that is deformable and has elastic properties.

[0064] Figure 6- Fig.10 As shown, the connection mechanism 200 may include an extended position and a retracted position. Figure 7 As shown, in the deployed position, the body 202 can be disposed on the connector 102 such that the first end 202A of the body 202 is positioned proximate 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 interior chamber 204. Since the second end 114B of the connector 102 is disposed within the interior chamber 204, the body 202 can completely surround the engagement surface 148 of the connector 102, thereby helping to prevent undesirable contamination of the engagement surface 148 when the connectors 102, 104 are not coupled. In addition, in the deployed position, a user can be prevented from coupling the connectors 102, 104 until the connection mechanism 200 is actuated.

[0065] refer to Figure 8 In the retracted position, the second end 202B of the body 202 can 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 interior chamber 204. Thus, the retracted position can allow the engagement surface 148 to be exposed. When the connection mechanism 200 is in the retracted position, the user can couple the connectors 102, 104.

[0066] Figures 6A-6D 104. 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 the deployed position and the 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. As a result, the second end 202B of the body 202 can be moved 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. With the connection mechanism 200 in the retracted position, the user can couple the connectors 102, 104 via the above process so that the connectors 102, 104 are as shown. Fig. 9 Make the connections as shown.

[0067] The user can then actuate the connection mechanism 200 to return the connection mechanism 200 to the deployed position, such as Fig.10 For example, a user may grasp the body 202 and slide the body 202 toward the second end 114B of the connector 202 so that the body 202 slides longitudinally along the connector 102. The body 202 may 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 interior chamber 204. With the connectors 102, 104 coupled and the connection mechanism 200 in the deployed position, the connection mechanism 200 may 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 be disengaged. In the event that the connectors 102, 104 are disengaged, the connection mechanism 200 can remain in the deployed position and disposed on the connector 102. In this way, after the connectors 102, 104 are 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 sterilized. Once disconnected, the user can actuate the connection mechanism 200 to the retracted position to allow the engagement surface 148 to be sterilized before the connectors 102, 104 are reconnected.

[0069] Features of the present disclosure provide a first compressible member and a second compressible member that can be used as valves to regulate a fluid passage between them. The first compressible member and the second compressible member are located in the first connector and the second connector, respectively. If the first connector and the second connector are separated, whether accidentally or intentionally, the fluid passage for each of the first compressible member and the second compressible member is 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, any one of the first compressible member and the second compressible member can be cleaned and disinfected, and the first compressible member and the second compressible member can be connected together again to form a fluid passage between them.
