Description

[Technical Field]

[0001] The present disclosure relates generally to connectors, and more particularly to connector couplings. [Background technology]

[0002] Medical procedures often involve the infusion of medical fluids (e.g., saline or liquid medications) into a patient using an intravenous (IV) catheter, which is connected to a source of fluid, such as an IV bag, through an arrangement of flexible tubing and connectors commonly referred to as an "IV set." Often, the tubing or catheter is connected or secured to one another to allow fluid communication between various portions of the tubing or catheter.

[0003] In some applications, such tubing or catheters may become dislodged due to being improperly secured and / or may become dislodged if the connection is subjected to forces greater than those the connection is designed to withstand. Summary of the Invention [Means for solving the problem]

[0020] It will be understood that various configurations of the subject technology will be readily apparent to those skilled in the art from this disclosure, and that various configurations of the subject technology are shown and described herein by way of example. As will be understood, the subject technology is capable of other different configurations, and its many details can be modified in various other respects, all without departing from the scope of the subject technology. Accordingly, the summary, drawings, and detailed description are to be regarded as illustrative in nature and not restrictive.

[0023] The disclosed coupler assembly includes a first connector, a collar, and a second connector. The collar is configured to couple the first connector to the second connector. The coupler assembly can have a first configuration and a second configuration. In the first configuration, the first connector is coupled to the collar, and the first connector and collar are coupled to the second connector. In the second configuration, the first connector is decoupled from the collar, and the collar is coupled to the second connector.

[0024] The coupler assembly may be configured to couple a first section of tubing to a second section of tubing. For example, the first section of tubing may be coupled to a first connector, and the second section of tubing may be coupled to a second connector. The first section of tubing and / or the second section of tubing may further be coupled to a patient or a fluid source. In some embodiments, the coupler assembly allows fluid to flow from the first section of tubing to the second section of tubing. For example, a collar may couple the first connector to the second connector, such that a fluid pathway is formed through the first and second connectors, thereby allowing fluid to flow from the first section of tubing through the first and second connectors to the second section of tubing. The fluid pathway may allow fluid to flow from the second section of tubing through the second and first connectors to the first section of tubing.

[0025] In some embodiments, the collar is configured to allow the first connector to be decoupled from the second connector. For example, the collar may couple the first connector to the second connector and may be configured to allow a disconnection event to decouple the first connector from the collar and second connector. The collar may allow the first connector to be unidirectionally connected to the collar and second connector. The first connector may be sanitized (e.g., with a sterilized cloth or sterilization device) or replaced with a new, sterile connector to prevent infection or sterilization that may occur if the first connector is reused without sterilization. In some embodiments, the first connector is configured to be decoupled based on a force exceeding a predetermined threshold force. When a force, such as a pull-out force, is applied to the first connector, the first connector may be decoupled from the collar and second connector. The pull-out force may be a force that occurs along the longitudinal axis of the first connector. In some embodiments, the pull-out force is provided by tugging or pulling a first section of tubing coupled to the first connector. Alternatively, the pull-out force applied to the first connector can be generated by tugging or pulling a second connector and / or a second section of tubing coupled to the second connector.

[0026] In some embodiments, the first connector is configured to reconnect to the collar when the first connector is disconnected from the collar and the second connector, For example, when the first connector is disconnected from the collar, the first connector may be configured to allow the first connector to reconnect to the collar after a disconnection event.

[0027] The detailed description set forth below is intended to be a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details to enable a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject technology. For ease of understanding, similar components are designated with the same element numbers. Reference numbers may have suffixes attached to indicate separate instances of common elements that are collectively referenced by the same number without the suffix.

[0028] While the following description is directed to a medical connector connection for administering medical fluids using the disclosed coupler, it will be understood that this description is merely an example of use and does not limit the scope of the claims. The various aspects of the disclosed coupler may be used in any application where it is desired to secure connections and connectors of various tubing types.

[0029] The disclosed coupler assembly overcomes several challenges found with certain conventional couplers. One challenge with certain conventional couplers is that they may be improperly secured. Furthermore, certain conventional couplers may be designed to release or disengage in response to relatively small pull-out forces during use. For example, certain conventional couplers may release in response to pull-out forces experienced when a patient turns in bed, when a patient grasps the tubing or line on a bed rail, when a patient transfers to another bed, when manipulated by a pediatric patient, and / or when a disoriented adult patient pulls on the line. In fact, at the 2017 Annual Scientific Meeting of the Association for Vascular Access (AVA), a 10% rate of disconnections was reported for every 1,000 patients fitted with peripheral IV catheters, which translates to approximately 33 million disconnections per year in the United States alone. The use of certain conventional couplers is undesirable because accidental or unintended disconnection of tubing, catheters, or fittings can disrupt the administration of medical fluids.

[0030] Therefore, in accordance with the present disclosure, it would be advantageous to provide couplers and coupler / connector assemblies as described herein that allow for improved securement of fittings or connectors. The disclosed couplers and coupler / connector assemblies are structured as described herein to allow for secure retention of the first connector while allowing for separation after a disconnection event.

Figure 4A is a side view of the coupler assembly of Figure 1 with the collar coupled to the second connector and the collar and second connector disconnected from the first connector, according to some embodiments of the present disclosure. Figure 4B is a side cross-sectional view of the coupler assembly of Figure 4A.

[0033] 1-4B , coupler assembly 100 fluidly and releasably couples a section of tubing or line to another section of tubing or line to allow fluid, such as medical fluid, to flow from a fluid source 500 to a patient end 600. Coupler assembly 100 may include a first connector 102, a collar 120, and a second connector 140. Collar 120 may be configured to couple first connector 102 to second connector 140. In the depicted example, a section of tubing may be terminated with a connector / valve, such as first connector 102 and / or second connector 140. In some embodiments, fluid from fluid source 500 flows through coupler assembly 100 to patient end 600. A cannula or needle may be inserted into the patient at the patient end 600, allowing medical fluid to flow from the fluid source 500, through the coupler assembly 100, and into the patient at the patient end 600. In some embodiments, disconnecting the first connector 102 from the second connector 140 obstructs or prevents flow from the fluid source 500 to the patient end 600.

[0034] In some embodiments, the coupler assembly 100 includes a central axis AA, along which the first connector 102, the collar 120, and the second connector 140 are serially coupled. The first connector 102 and / or the second connector 140 may allow for connection and / or disconnection of tubing to allow selective fluid communication therebetween. The central axis AA may extend longitudinally along the length of the first connector 102, the collar 120, and the second connector 140.

[0035] In some embodiments, the first connector 102 is coupled to the second connector 140 via a collar 120. The collar 120 may be configured to removably couple the first connector 102 to the second connector 140 such that a portion of the first connector 102 is disposed within the second connector 140. The collar 120 may be configured to allow for one-way connection of the first connector 102 to the collar 120. For example, the collar 120 may be configured to prevent reconnection of the first connector 102 to the collar 120 once the first connector 102 is disconnected from the collar 120. The collar 120 may be configured to allow for one-way connection of the first connector 102 to the collar 120.

[0036] The coupler assembly 100 may have a first configuration ( FIGS. 2A-2C ) and a second configuration ( FIGS. 4A-4B ). In the first configuration, the first connector 102 is coupled to the second connector 140 via the collar 120. In the second configuration, the first connector 102 is disconnected from the collar 120, and the collar 120 is coupled to the second connector 140. In some embodiments, the coupler assembly 100 transitions from the first configuration to the second configuration in response to a disconnection event. A disconnection event may occur when a pull-out force is applied to the first connector 102, causing the first connector 102 to move axially relative to the collar 120 and the second connector 140. In some embodiments, axial movement of the first connector 102 relative to the collar 120 and the second connector 140 is caused when the pull-out force applied to the first connector 102 exceeds a predetermined threshold force.

[0037] In some embodiments, a first connector 102 is coupled to a first section of tubing to allow the first section of tubing to be connected and / or disconnected to a second connector 140. The first connector 102 may include a first end 101 and a second end 103. The first end 101 may be coupled to the tubing (e.g., the first section of tubing), and the second end 103 may be configured to couple to a collar 120. In some embodiments, a section of tubing may be coupled to or engaged with the first end 101 of the first connector 102. The first connector 102 through the first end 101 may be in fluid communication with the tubing, thereby allowing fluid to pass through the first connector 102. In some embodiments, the first end 101 may have a flat surface to allow a clinician to easily clean and disinfect the first end 101. The first end 101 may be in fluid communication with the second end 103. The first end 101 and the second end 103 may be disposed along a longitudinal length of the first connector 102. For example, the first end 101 and the second end 103 may be disposed along a central axis AA. The first end 101 and / or the second end 103 may include an opening to allow the first end 101 and / or the second end 103 to be in fluid communication with one or more elements (e.g., tubing, connectors, valves, collars, fittings, etc.). For example, the first end 101 may be coupled to a tube, and the second end 103 may include an opening 110 to allow fluid communication through the first connector 102. In some embodiments, the first connector 102 includes a valve 104, where the valve 114 is configured to be at least partially disposed within the opening 110.

[0038] In some embodiments, fluid can exit or flow through the first connector 102 via a second end 103 disposed opposite the first end 101. The flow path through the first connector 102 can have a straight fluid path for easier flushing and to reduce the risk of hemolysis. Optionally, the first connector 102 can include structures (e.g., raised structures, gripping structures) disposed on an outer surface of the first connector 102 to allow a clinician to more easily handle or manipulate the first connector 102. Some embodiments of the first connector 102 can provide a connector that mates with connectors on other portions of a fluid delivery system. The first connector 102 can be molded to be substantially cylindrical.

[0039] In some embodiments, the first connector 102 includes a tubing section 107 disposed at the first end 101 and a mating section 105 disposed at the second end 103. The tubing section 107 may be configured to couple to a portion of the tubing, thereby allowing the first connector 102 to be in fluid communication with the portion of the tubing. For example, the tubing section 107 may include a channel 116 to allow fluid flow within the tubing section 107. The channel 116 may be disposed within the tubing section 107 and may extend the length of the tubing section 107.

[0040] In some embodiments, the mating portion 105 is disposed opposite the tubing portion 107, and the collar 120 is configured to couple to the mating portion 105 to secure the first connector 102 to the second connector 140. For example, the mating portion 105 may include a groove 109 configured to receive a portion of the collar 120 to secure the collar 120 to the first connector 102, and thus to couple the first connector 102 to the second connector 140, as described below. The groove 109 may be disposed on the mating portion 105 near the second end 103. In some embodiments, the groove 109 is configured to receive and engage a portion of the collar 120 to secure the first connector 102 to the collar 120.

[0041] In some embodiments, the first connector 102 includes a body 111 and a valve 104. The body 111 may extend from the tubing section 107. For example, the body 111 may extend away from the tubing section 107 toward the second end 103. In some embodiments, the body 111 and the tubing section 107 are formed of a single structure. Alternatively, the body 111 may be fixedly or removably coupled to the tubing section 107. In some embodiments, the body 111 includes a channel 113. The channel 113 may be disposed within the body 111 and may be in fluid communication with the channel 116 of the tubing section 107. For example, the tubing section 107 may be coupled to a fluid source 500 through a portion of the tubing, thereby allowing fluid to flow from the fluid source 500 into the channel 116. Fluid may flow from the channel 116 into the channel 113 of the body 111.

[0042] The first connector 102 may include an internal cavity 119, which is the space between the body 111 and the mating portion 105. For example, the mating portion 105 may be a cylinder extending from the tubing portion 107, and the body 111 may be disposed within the mating portion 105. The cavity 119 may be the space between the exterior surface of the body 111 and the interior surface of the mating portion 105.

[0043] Body 111 may include a coupling surface 108 disposed at an end of body 111 and a fluid opening 112 disposed between body 111 and coupling surface 108. For example, coupling surface 108 may be disposed near second end 103, and fluid opening 112 may be disposed between body 111 and second end 103. In some embodiments, fluid opening 112 is in fluid communication with channel 113, allowing fluid within channel 113 to flow through fluid opening 112. Coupling surface 108 may be at least partially disposed within opening 110.

[0044] In some embodiments, the body 111 includes the valve 104. The valve 104 may include a biasing element 106 and a distal end 117. The valve 104 may be disposed between the tubing portion 107 and the second end 103. In some embodiments, the body 111 is disposed within the valve 104. For example, the body 111 may extend at least partially through the valve 104. In some embodiments, the valve 104 surrounds the body 111.

[0045] A biasing element 106 can be coupled to the distal end 117. In some embodiments, the distal end 117 is disposed near the second end 103, and the biasing element 106 is disposed closer to the first end 101 than the distal end 117. The biasing element 106 can be configured to allow the valve 104 to compress and expand. For example, the valve 104 can be configured to compress (e.g., decrease in length) or expand (e.g., increase in length). The biasing element 106 can be a spring or spring-like structure that allows the valve 104 to assume a compressed state ( FIG. 2B ) or an expanded state ( FIG. 4B ). In some embodiments, the biasing element 106 couples the valve 104 to the tubing section 107 such that the valve 104 compresses (e.g., transitions to a compressed state) when an axial force is applied to the valve 104 toward the first end 101.

[0046] In some embodiments, the valve 104 is biased to an inflated state such that the valve 104 is at least partially disposed within the opening 110. In the inflated state, the distal end 117 of the valve 104 can be at least partially disposed within the opening 110 at the second end 103. In some embodiments, the distal end 117 is configured to surround the coupling surface 108 when the valve 104 is in the inflated state, thereby rendering the opening 110 substantially fluid-tight. For example, when the valve 104 is in the inflated state, the distal end 117 at least partially blocks the fluid opening 112, thereby preventing fluid from exiting the fluid opening 112.

[0047] In some embodiments, when the valve 104 is in a compressed state, the valve 104 (e.g., distal end 117) may not block the fluid opening 112, thereby allowing fluid to flow from the channel 113 through the fluid opening 112. In the compressed state, the valve 104 may be disposed between the first end 101 and the second end 103. For example, in the compressed state, the valve 104 may have a length that is less than the length of the valve 104 when the valve 104 is in the expanded state. In some embodiments, when the valve 104 is in a compressed state, the distal end 117 is disposed between the tubing section 107 and the fluid opening 112. In the compressed state, the distal end 117 allows fluid to exit the body 111 through the fluid opening 112 but prevents backflow or buildup of fluid. For example, distal end 117 can surround a portion of body 111 between fluid opening 112 and where body 111 extends from tubing portion 107. Distal end 117 can be configured to surround body 111 to prevent liquid from flowing past distal end 117 and into cavity 119.

[0048] In some embodiments, a second section of tubing is terminated by a second connector 140, which allows the second section of tubing to be connected and / or disconnected to the first connector 102 via the collar 120. The second connector 140 may include a first end 141 and a second end 143 disposed opposite the first end 141. The first end 141 may include a housing 144, and the second end 143 may include a connecting portion 145, which may be disposed opposite the housing 144. In some embodiments, a section of tubing couples or engages with the connecting portion 145 of the second connector 140. In some embodiments, the connecting portion 145 includes a threaded connection to facilitate coupling to the tubing. For example, the connecting portion 145 may include a connecting portion 145 configured to couple to the section of tubing.

[0049] In some embodiments, the housing 144 includes structure (e.g., threads) that allows the second connector 140 to mate with the collar 120. The housing 144 may be mated or otherwise engaged with the second end 123 of the collar 120 to allow fluid communication between the first connector 102 and the second connector 140 and the portions of tubing connected thereto when the first connector 102 is coupled to the collar 120. As can be appreciated, the first connector 102 and the second connector 140 can be coupled and decoupled via the collar 120 to allow fluid communication as desired. The first connector 102 can be removably coupled to the second connector 140 via the collar 120 to provide a needle-free connection. Advantageously, the first connector 102 can be mated with the second connector 140 via the collar 120 to form a leak-free closed system, thereby allowing for the delivery of various medications or fluids.

[0050] In some embodiments, second connector 140 includes a connecting portion 145 disposed opposite housing 144. Housing 144 may extend from connecting portion 145. Connecting portion 145 may include a channel 149 disposed within connecting portion 145. Channel 149 may include an inlet 151, which may be disposed between first end 141 and second end 143. In some embodiments, inlet 151 has a maximum width (e.g., diameter) that is greater than the maximum width (e.g., diameter) of channel 149. Inlet 151 may be in fluid communication with channel 149, such that liquid entering inlet 151 flows into channel 149 and through tubing portion 145.

[0051] The connecting portion 145 can be configured to couple to a section of tubing (e.g., tubing coupled to the patient end 600) such that the channel 149 is in fluid communication with the section of tubing. In some embodiments, the interior surface of the connecting portion 145 includes threads for coupling or mating with the section of tubing, thereby allowing the second connector 140 to be in fluid communication with the section of tubing.

[0052] The housing 114 may extend from the connecting portion 145 toward the first end 141. The housing 144 may include a cavity 157 disposed within the housing 144. The cavity 157 may be an interior space within the housing 144. The housing 144 may include a distal end 164, which may include an opening 159. In some embodiments, the housing 144 includes a tapered portion 142 disposed between the connecting portion 145 and the first end 141 (e.g., opening 159). The tapered portion 142 may be configured to secure the collar 120 to the second connector 140, as described below.

[0053] In some embodiments, the second connector 140 includes a distribution portion 162. The distribution portion 162 may be disposed near the channel 149. For example, the distribution portion 162 may be disposed at an opening of the channel 149. In some embodiments, the distribution portion 162 is disposed at or near where the housing 144 extends from the connecting portion 145. The distribution portion 162 may be disposed at least partially within the inlet 151. In some embodiments, the distribution portion 162 is disposed within or near the inlet 151. The distribution portion 162 may cause fluid entering the inlet 151 to deflect around the distribution portion 162 before entering the inlet 151 and flowing through the channel 149. In some embodiments, the distribution portion 162 is coupled to and extends from a portion of the housing 144. For example, in some embodiments, the distribution portion 162 is integrally formed with the housing 144 and includes apertures or passages that allow fluid to flow through the distribution portion via the inlet 151 .

[0054] In some embodiments, the second connector 140 includes a valve 148. The valve 148 may include a biasing element 155 and a distal end 153. The valve 148 may be disposed between the dispensing portion 162 and the first end 141. In some embodiments, the valve 148 is disposed within a cavity 157. For example, the valve 148 may be housed within the cavity 157.

[0055] A biasing element 155 can be coupled to the distal end 153. In some embodiments, the distal end 153 is disposed near the second end 143, and the biasing element 155 is disposed closer to the first end 141 than the distal end 153. The biasing element 155 can be configured to allow the valve 148 to compress and expand. For example, the valve 148 can be configured to compress (e.g., decrease in length) or expand (e.g., increase in length). The biasing element 155 can be a spring or spring-like structure that allows the valve 148 to assume a compressed state ( FIG. 2B ) or an expanded state ( FIG. 4B ). In some embodiments, the biasing element 155 couples the valve 148 to the dispensing portion 162 such that the valve 148 compresses (e.g., transitions to a compressed state) when an axial force is applied to the valve 148 toward the second end 143.

[0056] In some embodiments, valve 148 is biased to an inflated state such that valve 148 is at least partially disposed within opening 159. In the inflated state, distal end 153 of valve 148 may be at least partially disposed within opening 159 at second end 143. In some embodiments, distal end 153 is configured to seal opening 159 when valve 148 is in the inflated state, such that opening 159 is substantially fluid-tight. For example, when valve 148 is in the inflated state, distal end 153 at least partially blocks opening 159, thereby preventing fluid from entering or exiting through opening 159.

[0057] In some embodiments, when valve 148 is in a compressed state, valve 148 (e.g., distal end 153) can unblock opening 159, thereby allowing fluid to flow into opening 159. Fluid can flow into opening 159, through cavity 157, around distribution portion 162, and into channel 159. In the compressed state, valve 148 can be disposed between opening 159 and distribution portion 162. For example, in the compressed state, valve 148 may have a length that is less than the length of valve 148 when valve 148 is in an expanded state. In some embodiments, when valve 148 is in a compressed state, distal end 153 is disposed between opening 159 and distribution portion 162, such that distal end 153 is disposed within cavity 157. In the compressed state, distal end 153 allows fluid to enter or exit housing 144 (e.g., cavity 157) through opening 159. When the valve 148 is in a compressed state, fluid may be allowed to flow from the opening 159 , through the cavity 157 , around the distribution portion 162 and into the channel 149 .

[0058] 2A-2D , when the first connector 102 is coupled to the second connector 140 via the collar 120, the coupling surface 108 of the first connector 102 may apply an axial force to the valve 148, thereby placing the valve 148 in a compressed state. Furthermore, by coupling the first connector 102 to the second connector 140, the distal end 164 may apply an axial force to the valve 104, thereby placing the valve 104 in a compressed state. In some embodiments, when the first connector 102 is coupled to the second connector 140 via the collar 120, at least a portion of the second connector 102 is disposed within the first connector 102.

[0059] When the first connector 102 is coupled to the second connector 140 via the collar 120, the valves 104 and 148 are in a compressed state, thereby forming a fluid pathway (see FIG. 2D ) between the first connector 102 and the second connector 140. For example, the distal end 164 may abut the valve 104, thereby compressing the valve 104 and disposing the distal end 164 within the first connector 102 (e.g., cavity 119). At the same time, the coupling surface 108 may abut the valve 148, thereby compressing the valve 148 and disposing the coupling surface 108 within the second connector 140 (e.g., cavity 157). This places the fluid opening 112 in fluid communication with the cavity 157.

[0060] 2D , when coupler assembly 100 is in a first configuration (e.g., when first connector 102 is coupled to second connector 140 via collar 120), a fluid pathway is formed. In the first configuration, fluid may flow into first connector 102 by entering body 111 via channel 116. Fluid may then flow within channel 113 of body 111 and through fluid opening 112 into cavity 157. Fluid may then flow around valve 148 and distribution portion 162, into inlet 151, and out of second connector 140 through channel 149.

[0061] 2A-4B , the second connector 140 may be coupled to the first connector 102 via a collar 120. The collar 120 may include a first end or first collar end 121 and a second end or second collar end 123. The first end 121 of the collar 120 may be configured to couple to the first connector 102, and the second end 123 of the collar 120 may be configured to couple to the second connector 140. In some embodiments, the first end 121 of the collar 120 couples to the second end 103 of the first connector 102, and the second end 123 of the collar 120 couples to the first end 141 of the second connector 140. The second end 123 of the collar 120 may be configured to couple to a housing 144 of the second connector 140. The collar 120 may be constructed from a flexible or semi-flexible material. For example, the collar 120 may be constructed from rubber. In some embodiments, at least a portion of the collar 120 is constructed from a flexible material.

[0062] In some embodiments, the collar 120 includes a locking rim 127 configured to engage with the tapered portion 142. The locking rim 127 may be disposed at or near the second end 123. The tapered portion 142 may include a groove 147 configured to engage with the locking rim 127. In some embodiments, the collar 120 may be secured to the second connector 140 by inserting the second connector 140 through the collar 120 to engage the locking rim 127 with the tapered portion 142. The collar 120 may be secured to the second connector 140 by axially moving the collar 120 toward the second end 143 of the second connector 140 until the locking rim 127 is disposed within the groove 147. Once the locking rim 127 is disposed within the groove 147, the collar 120 is secured to the second connector 140. In some embodiments, the groove 147 receives the fixed rim 127 to prevent axial movement of the collar 120 relative to the second connector 140 along the central axis AA.

[0063] 2A-3 , the collar 120 may include an engagement edge 125. The engagement edge 125 may be disposed at or near the first end 121. The engagement edge 125 may extend radially inward from the first end 121. In some embodiments, the engagement edge 125 is a barbed rubber edge angled toward the second end 123 to allow for one-way insertion of the first connector 102. For example, the first connector 102 may be inserted into the collar 120, and the collar 120 may be coupled to the second connector 140 (e.g., via the retaining rim 127 and the groove 147). When the first connector 102 is inserted into the collar 120, the engagement edge 125 may engage with the groove 109. In some embodiments, the first connector 102 is coupled to the collar 120 by disposing the engagement edge 125 in the groove 109 of the mating portion 105. The engagement edge 125 may be angled radially inward to allow the first connector 102 to move axially relative to the collar 120 toward the second end 123 of the collar 120 until the engagement edge 125 is disposed within the groove 109. Additionally, the engagement edge 125 may be angled radially inward to limit the axial movement of the first connector 102 relative to the collar 120 toward the first end 121 when the first connector 102 is coupled to the collar 120. In some embodiments, the engagement edge 125 may be disposed within the groove 109 to prevent the collar 120 (e.g., the engagement edge 125) from applying a radially inward force (e.g., force F) to the mating portion 105 (e.g., the groove 109 and / or the sidewall 114). A ) is added.

[0064] 2A-2D , coupler assembly 100 is in a first configuration when second connector 140 is coupled to collar 120 by securing rim 127 within groove 147, and when first connector 102 is coupled to collar 120 and second connector 140 by securing engagement edge 125 within groove 109. Engagement edge 125 may be disposed within groove 109 and abut sidewall 114, thereby preventing axial movement of first connector 102 relative to collar 120. Engagement edge 125 abutting sidewall 114 may prevent axial movement of first connector 102 away from collar 120.

[0065] In some embodiments, in the first configuration, the valve 104 applies an axial force to the housing 144 and the valve 148 applies an axial force to the mating surface 108, thereby biasing the first connector 102 and the second connector 140 to disconnect. The collar 120 coupled to the second connector 140 and the first connector 102 may counter this bias by preventing axial movement of the second connector 140 and the first connector 102 relative to the collar 120.

[0066] 4A-4B, coupler assembly 100 may be configured to a second configuration. In the second configuration, first connector 102 is decoupled from collar 120, and collar 120 remains coupled to second connector 140. In the second configuration, valves 104 and 148 return to their biased and inflated states, blocking the fluid path between first connector 102 and second connector 140. In some embodiments, valve 104 returning to its inflated state seals opening 110, preventing fluid flow into / out of first connector 102. In some embodiments, valve 148 returning to its inflated state seals opening 159 by valve 148 (e.g., distal end 153), preventing fluid flow into / out of second connector 140. In the second configuration, the collar 120 may be coupled to the second connector 140 by the locking rim 127 being disposed within the groove 147, thereby preventing axial movement of the second connector 140 relative to the collar 120. The coupler assembly 100 may be transitioned from the first configuration to the second configuration by the first connector 102 being decoupled from the collar 120 when the collar 120 is coupled to the second connector 140.

[0067] In some embodiments, the first connector 102 is secured to the second connector 140 via the collar 120, and the first connector 102 is configured to be decoupled from the collar 120. In some embodiments, the first connector 102 is configured to be decoupled from the collar 120 by a disconnection event caused by a pull-out force. For example, a pull-out force (e.g., force F) may be applied to the first connector 102 directly or indirectly, such as by being applied to tubing coupled to the first connector 102. The pull-out force may axially move the first connector 102 away from the collar 120 and the second connector 140 along the central axis AA, thereby decoupling the first connector 102 from the collar 120 and the second connector 140.

[0068] In some embodiments, when the force F exceeds a predetermined threshold force, the first connector 102 is decoupled from the collar 120 and, therefore, the second connector 140. For example, if the force F is less than the predetermined threshold force, the first connector 102 may not be decoupled from the collar 120 and the second connector 140. The predetermined threshold force prevents accidental or unintentional decoupling based on small forces or small movements. The predetermined threshold force may be based on the flexibility and / or inflexibility of the engagement edge 125. For example, as the inflexibility of the engagement edge 125 increases, the predetermined threshold force increases. In some embodiments, when the withdrawal force exceeds the predetermined threshold force, the engagement edge 125 may fail by breaking or the engagement edge 125 may be temporarily or permanently bent back toward the first connector 102, thereby allowing the first connector 102 to be decoupled from the collar 120.

[0069] In some embodiments, the predetermined threshold force is about 4 pounds (lb). The predetermined threshold force may be about 1 lb to about 8 lb, about 3 lb to about 7 lb, about 4 lb to about 6 lb, or greater than about 8 lb. For example, a patient may have a needle / catheter inserted into the patient's skin, and the needle / catheter may be coupled to the first connector 102 or the second catheter 140. The patient may walk away from the infusion pump or may accidentally pull on a fluid line coupled to the first connector 102 or the second connector 140, and if the force exceeds 4 lb, the first connector 102 may automatically release or become disconnected from the collar 120, thereby effectively closing the fluid path between the first connector 102 and the second connector 140, as described herein.

[0070] When a disconnection event separates the first connector 102 from the collar 120, the collar 120 may remain fixedly coupled to the second connector 140. The first connector 102 may be separated from the collar 120 in response to a force F exceeding a predetermined threshold force. When the force F exceeds the predetermined threshold force, the sidewall 114 presses against the engagement edge 125, and the force F A , causing the first end 121 (e.g., engagement edge 125) to deflect radially outward and displace from the groove 109. For example, in response to a pull-out force (e.g., axial force F) that exceeds a predetermined threshold force, the first connector 102 may move axially relative to the collar 120, resulting in F A , causing the first end 121 to bend radially outward and disengage from the groove 109, and the collar 120 is no longer secured to the first connector 102.

[0071] In some embodiments, the collar 120 does not include the engagement edge 125. The collar 120 may be configured to couple to the first connector 102 and to prevent the first connector 102 from decoupling when the force F is less than a predetermined threshold force. For example, the collar 120 may include a compressible material that abuts or engages with the groove 109 and is thereby disposed within the groove 109. The compressible material may be configured to exert a compressive force on the groove 109, thereby securing the first connector 102 in place and relative to the collar 120. In response to a force F that exceeds the predetermined threshold force, the compressible material may be configured to compress the mating portion 105 to slide off the collar 120, thereby allowing the first connector 102 to be decoupled from the collar 120.

[0072] In some embodiments, once the first connector 102 is disconnected from the collar 120 and the second connector 140, a user sanitizes the first connector 102 and recouples the first connector 102 to the collar 120. In some embodiments, a user can sanitize the first connector 102, the second connector 140, and / or the collar 120. The first connector 102 can be recoupled to the collar 120 by inserting the first connector 102 into the collar 120, such that the second connector 140 is disposed within the first connector 102. The first connector 102 can be moved axially relative to the collar 120 to couple the first connector 102 to the collar 120 and the second connector 140 by engaging the groove 109 with the engagement edge 125, thereby securing the collar 120 to the first connector 102 and securing the first connector 102 to the second connector 140. Recoupling of first connector 102 to collar 120 transitions coupler assembly 100 from the second configuration to the first configuration.
