[0025] It should be understood that, according to the present disclosure, the various structures of the subject technology will become clear to those skilled in the art, wherein the various structures of the subject technology are shown and described by way of illustration. As will be appreciated, the subject technology can have other and different configurations and its several details can be modified in various other aspects, all without departing from the scope of the subject technology.

[0034] The disclosed connector coupling assembly or coupling assembly includes a first connector and a second connector. The first connector is configured to be coupled to the second connector. The coupling assembly may have a first configuration and a second configuration. In the first configuration, the first connector is coupled to the second connector. In the second configuration, the first connector is separated from the second connector.

[0035] The coupling assembly can be configured to couple a first portion of a tubing to a second portion of a tubing. For example, the first portion of the tubing can be coupled to a first connector, and the second portion of the tubing can be coupled to a second connector. The first portion of the tubing and / or the second portion of the tubing can also be coupled to a patient or a fluid source. In some embodiments, the coupling assembly allows fluid to flow from the first portion of the tubing to the second portion of the tubing. For example, a first connector can be coupled to a second connector so that a fluid passage through the first connector and the second connector is formed to allow fluid to flow from the first portion of the tubing through the first connector and the second connector to the second portion of the tubing. The fluid passage can allow fluid to flow from the second portion of the tubing through the second connector and the first connector to the first portion of the tubing.

[0036] In some embodiments, the first connector and the second connector provide a unidirectional fluid flow. For example, when the first connector is coupled to the second connector, the fluid can flow from the second connector to the first connector, rather than from the first connector to the second connector. In some embodiments, the separation of the first connector from the second connector causes the fluid flow from the second connector to the first connector to stop, thereby preventing leakage when the first connector is separated from the second connector. In some embodiments, when the first connector is separated from the second connector, the first connector is sterilized (for example, via a sterilized cloth or sterilizing device) or replaced by a new sterile connector to prevent infection or contamination that may occur if the first connector is reused without sterilization. In some embodiments, the first connector is configured to separate based on a force exceeding a predetermined threshold force. When a force exceeding a predetermined threshold force (such as a pull-out force) is applied to the first connector, the first connector can be separated from the second connector. The pull-out force can be a force generated along the longitudinal axis of the first connector. In some embodiments, the pull-out force is generated by dragging or pulling the first part of the pipe fitting coupled to the first connector. Alternatively, the pull-out force applied to the first connector can be generated by dragging or pulling the second connector and / or the second part of the pipe fitting coupled to the second connector.

[0037] In some embodiments, once the first connector is separated from the second connector, the first connector is configured to reconnect to the second connector. For example, once the first connector is separated from the second connector (e.g., due to a disconnection event), the first connector can be configured to allow reconnection to the second connector after the disconnection event.

[0038] The detailed description set forth below is intended to be a description of the various configurations of the subject technology, and is not intended to represent the unique configuration that can practice the subject technology. The specific embodiments include specific details for the purpose of providing a thorough understanding of the subject technology. However, it is clear to those skilled in the art that the subject technology can be implemented without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring the concept of the subject technology. For ease of understanding, identical components are marked with identical element numbers. Reference numerals may be appended with letter suffixes to indicate individual instances of common elements, and are generally referred to by identical numerals without suffix letters.

[0039] Although the following description relates to the connection of medical accessories for the administration of medical fluids using the disclosed coupling, it should be understood that the description is merely an example of use and does not limit the scope of the claims. The various aspects of the disclosed coupling can be used in any application where it is desired to secure the connection of various tubing and accessories.

[0040] The disclosed connector assembly overcomes multiple challenges found with respect to certain conventional connectors. One challenge with certain conventional connectors is that certain conventional connectors may be improperly fixed. In addition, during use, certain conventional connectors may be designed to release or shift in response to relatively low pull-out forces. For example, during a patient turning over in bed, a patient grabbing tubing or lines on a bed rail, moving a patient to a different bed, pediatric patients fidgeting, and / or adult patients who lose their sense of direction pulling out their lines, certain conventional connectors may release in response to the pull-out forces experienced. In fact, the 2017 Vascular Access Association (AVA) Annual Scientific Meeting reported that the displacement rate for 1000 patients with peripheral IV catheters was 10%, with approximately 33 million displacements occurring each year in the United States alone. Because the accidental or unintentional displacement of tubing, catheters, or accessories may interrupt the administration of medical fluids, it is undesirable to use certain conventional connectors.

[0041] Therefore, according to the present disclosure, it is advantageous to provide a coupler and coupler / connector assembly as described herein that allows improved fixation of an accessory or connector. The disclosed coupler and coupler / connector assembly are constructed as described herein to allow secure retention of a first connector while allowing separation after a disconnection event.

[0044] Reference Figure 1-Figure 5 , a connector coupling assembly ("coupler assembly" or "coupler") 100 allows a fluid (such as a medical fluid) to flow from a fluid source 500 to a patient end 600 by releasably coupling a portion of a tubing or line to another portion of a tubing or line in fluid communication. The coupler assembly 100 may include a first connector 102 and a second connector 140. The first connector 102 may be configured to be coupled to the second connector 140. In some embodiments, the first connector 102 and / or the second connector 140 are one-way connectors. In the depicted example, a portion of the tubing may be terminated with a connector / valve, such as the first connector 102 and / or the second connector 140. In some embodiments, a fluid from a fluid source 500 flows through the coupler assembly 100 to a patient end 600. A cannula or needle may be inserted into a patient's body at the patient end 600, thereby allowing a medical fluid to flow from the fluid source 500 through the coupler assembly 100 into the patient's body at the patient end 600. In some embodiments, separation of the first connector 102 from the second connector 140 interrupts or prevents flow from the fluid source 500 to the patient end 600 .

[0045] In some embodiments, the coupling assembly 100 includes a central axis AA, and the first connector 102 and the second connector 140 are coupled in series along the central axis AA. The first connector 102 and / or the second connector 140 can allow for connection and / or disconnection of pipes to allow for selective fluid communication therebetween. The central axis AA can extend longitudinally along the length of the first connector 102 and the second connector 140.

[0046] The coupling assembly 100 may have a first configuration ( Figure 2 ) and the second construction ( Figure 6). In the first configuration, the first connector 102 is coupled to the second connector 140. In the second configuration, the first connector 102 is separated from the second connector 140. In some embodiments, the coupling assembly 100 switches from the first configuration to the second configuration in response to a disconnection event. Disconnection may even occur when a pull-out force is applied to the first connector 102, causing the first connector 102 to move axially relative to the second connector 140. In some embodiments, when the pull-out force applied to the first connector 102 exceeds a predetermined threshold force, causing the first connector 102 to move axially relative to the second connector 140.

[0047] In some embodiments, the first connector 102 is coupled to a first portion of a tubing to allow the first portion of the tubing to be connected and / or disconnected from the 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 a tubing (e.g., a first portion of a tubing), and the second end 103 may be configured to be coupled to the second connector 140. In some embodiments, a portion of the tubing may be coupled or engaged with the first end 101 of the first connector 102. The first connector 102 may be in fluid communication with the tubing via the first end 101 to allow 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 fluidly connected to the second end 103. The first end 101 and the second end 103 may be arranged along the longitudinal length of the first connector 102. For example, the first end 101 and the second end 103 may be arranged along the 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., a fitting, a connector, a valve, a collar, an accessory, etc.). For example, the first end 101 may be coupled to a tube, and the second end 103 may include a channel 134 to allow fluid to communicate through the first connector 102. The channel 134 may be configured to receive a portion of the second connector 140 (e.g., the coupling portion 150) to secure the second connector 140 to the first connector 102. In some embodiments, the channel 134 includes a distal or outer edge 133. The edge 133 may be disposed proximate to the second end 103. In some embodiments, when the first connector 102 is coupled to the second connector 140, a portion of the second connector 140 (e.g., the coupling portion 150) extends through the second end 103.

[0048] In some embodiments, the first connector 102 is configured to be coupled to the second connector 140 such that fluid flows into the first connector 102 and flows out of the second connector 140. For example, the first connector 102 may include an inlet (e.g., inlet 115) configured to receive the fluid, and the second connector 140 may include an outlet (e.g., outlet 170) configured to allow the fluid to exit the second connector 140. In some embodiments, the first connector 102 is coupled to the second connector 140 such that the inlet (e.g., inlet 115) of the first connector 102 is in fluid communication with the outlet (e.g., outlet 170) of the second connector 140.

[0049] In some embodiments, the fluid can flow out or flow through the first connector 102 via the second end 103 disposed opposite the first end 101. The flow path through the first connector 102 can have a straight fluid passage to make flushing easier and reduce the risk of hemolysis. Optionally, the first connector 102 may include features (e.g., raised features, gripping features) disposed on the outer surface of the first connector 102 to allow the clinician to more easily operate or manipulate the first connector 102. Some embodiments of the first connector 102 can provide a connector that is compatible with connectors of other parts of the fluid delivery system. The first connector 102 can be substantially cylindrical in shape.

[0050] In some embodiments, the first connector 102 includes an inlet portion 120 disposed proximate to the first end 101 and a mating portion 130 disposed proximate to the second end 103. The inlet portion 120 can be configured to be coupled to a portion of the tubing to allow fluid communication between the first connector 102 and the portion of the tubing. For example, the inlet portion 120 can include an inlet 115 configured to allow fluid to enter the inlet portion 120. The inlet portion 120 can also include a channel 113 to allow fluid to flow within the inlet portion 120. The channel 113 can be disposed within the inlet portion 120 and extend from the first end 101 of the inlet portion 120 to the body 116.

[0051] In some embodiments, the mating portion 130 is disposed opposite the entry portion 120 and is configured to couple to the second connector 140 to secure the first connector 102 to the second connector 140. For example, the mating portion 130 may include one or more grooves 136 configured to receive a portion of the second connector 140 to secure and couple the first connector 102 to the second connector 140, as described below. The groove 109 may be disposed on the mating portion 130 proximate the second end 103. In some embodiments, the groove 136 is configured to receive and engage a portion of the second connector 140 to secure the first connector 102 to the second connector 140.

[0052] refer to Figure 2-Figure 3 , the inlet portion 120 can be coupled to the mating portion 130 between the first end 101 and the second end 103. The inlet portion 120 can be disposed proximate to the first end 101 and can include a channel 113 and an interior space 117. The channel 113 can lead to the interior space 117. For example, the channel 113 can be in fluid communication with the interior space 117. In some embodiments, a portion of the tube is coupled to the inlet portion 120 such that the portion of the tube is in fluid communication with the channel 113. The portion of the tube in fluid communication with the channel 113 also causes the portion of the tube to be in fluid communication with the interior space 117.

[0053] In some embodiments, the inlet portion 120 includes a body 116 coupled to the channel 113. The body 116 may include an interior space 117. The diameter of the channel 113 may be smaller than the inner diameter of the body 116. In some embodiments, the volume of the channel 113 is smaller than the volume of the interior space 117 of the body 116. The channel 113 may be in fluid communication with the interior space 117 of the body 116, such that the body 116 (e.g., the interior space 117) is configured to accommodate a larger volume of liquid than the channel 113.

[0054] The mating portion 130 may be disposed proximate to the second end 103 and may include an opening 110, an interior space 132, and a channel 134. The opening 110 may be in fluid communication with the interior space 132 and the channel 134. In some embodiments, the opening 110 is in fluid communication with the interior space 117 of the inlet portion 120. For example, the opening 110 may be in fluid communication with the interior space 117 so that the fluid flows from the channel 113 into the interior space 117 and into the opening 110. The fluid may then flow from the opening 110 through the interior space 132 and out of the first connector 102 via the channel 134. In some embodiments, when the first connector 102 is coupled to the second connector 140, the channel 134 allows the fluid to flow out of the first connector 102 and into the second connector 140. The diameter of the opening 110 may be smaller than the diameter of the channel 134. In some embodiments, the channel 134 has substantially the same diameter as the body 116. In some embodiments, the first connector 102 is formed by coupling the inlet portion 120 to the mating portion 130. Alternatively, the first connector 102 is formed of a unitary member.

[0055] refer to Figure 3, the first connector 102 may include a valve 104. The valve 104 may be disposed within the interior space 117 of the body 116. In some embodiments, the valve 104 extends at least partially into the mating portion 130. For example, the valve 104 may extend from the inlet portion 120 (e.g., the interior space 117) to the opening 110 of the mating portion 130. In some embodiments, the valve 104 is configured to seal the opening 110 to prevent fluid from flowing out of the first connector 102 (e.g., leaking). For example, the valve 104 may be configured to seal the opening 110 to close the fluid communication between the interior space 117 of the inlet portion 120 and the interior space 132 of the mating portion 130. In some embodiments, the opening 110 is sized and shaped to match the profile of the valve 104, thereby allowing the valve 104 to seal the opening 110. The valve 104 may have any shape configured to seal the opening 110. In some embodiments, the first connector 102 allows a one-way flow of fluid. For example, the first connector 102 and / or the valve 104 may allow the fluid to flow out of the opening 110, but not into the opening 110.

[0056] The valve 104 can have a first end 105 and a second end 107. The second end 107 can be disposed opposite the first end 105. In some embodiments, the first end 105 and the second end 107 have substantially flat faces or surfaces. The surface of the first end 105 can be substantially parallel to the surface of the second end 107. In some embodiments, the length and / or width of the surface of the second end 107 is less than the length and / or width of the surface of the first end 105.

[0057] The valve 104 can be coupled to a biasing element 119. In some embodiments, the valve 104 is coupled to the biasing element 119 at the first end 105. The biasing element 119 can be a spring or a spring-like structure to allow the biasing element 119 to be in a compressed state or an expanded state. The biasing element 119 can be disposed within the interior space 117. In some embodiments, the biasing element 119 is disposed proximate to the first end 101. The biasing element 119 can be disposed within the body 116 such that the biasing element 119 is located within the interior space 117. In some embodiments, the biasing element 119 has a first end 121 disposed proximate to the channel 113 and a second end 123 disposed proximate to the valve 104. The valve 104 can be coupled to the biasing element at the second end 123. For example, the second end 123 can be coupled to the first end 105 of the valve 104. The first end 121 can be coupled to the distal end 111 of the channel 113. For example, the channel 113 can turn into the interior space 117 at the distal end 111 of the channel 113. In some embodiments, the biasing element 119 is coupled to the distal end 111 of the channel 113 .

[0058] The biasing element 119 can have a compressed state and an expanded state. For example, the biasing element 119 can be configured to compress (e.g., shorten in length) or expand (e.g., increase in length). The biasing element 119 can be biased to the expanded state. In the compressed state, the second end 123 is arranged to be close to the first end 121 and the distal end 111 of the channel 113. In the expanded state, the second end 123 can be arranged away from the first end 121. Since the valve 104 is connected to the second end 123, the valve 104 is arranged to be close to the first end 121 and the distal end 111 in the compressed state compared to when the biasing element 119 is in the expanded state. In some embodiments, when the biasing element 119 is in the expanded state, the valve 104 is arranged away from the first end 121 and is at least partially arranged in the opening 110. In some embodiments, the valve 104 extends at least partially through the opening 110 to seal the opening 110. The valve 104 is at least partially disposed within the opening 110 and partially extends through the opening 110 such that the opening 110 is sealingly isolated from the interior space 117. For example, the biasing element 119 can be in an expanded position such that the valve 104 is at least partially disposed within the opening 110. The valve 104 disposed within the opening 110 prevents the inlet portion 120 (e.g., the passage 113 and the interior space 117) from fluidly communicating with the mating portion 130 (e.g., the interior space 132 and the passage 134).

[0059] In some embodiments, the biasing element 119 in the expanded state causes the valve 104 to be in the expanded state and to extend at least partially through the opening 110. In some embodiments, when the valve 104 and the biasing element 119 are in the expanded state, the second end 107 is disposed through the opening 110. For example, when the valve 104 and the biasing element 119 are in the expanded state, the opening 110 can be disposed between the first end 105 and the second end 107.

[0060] In some embodiments, the valve 104 is pushed or pressure / force is applied to the valve 104 via another structure to place the biasing element 119 in a compressed state, thereby causing fluid communication between the mating portion 130 and the inlet portion 120. When the pressure / force is removed from the valve 104, the biasing element 119 can return to an expanded state, thereby causing the valve 104 to be at least partially disposed within the opening 110, which causes the inlet portion 120 to no longer be in fluid communication with the mating portion 130.

[0061] refer to Figure 1 and Figure 4, the first connector 102 may be configured to be coupled to the second connector 140. The second connector 140 may include a coupling portion 150 and an output portion 160. The coupling portion 150 may be configured to be coupled to the output portion 160. In some embodiments, the coupling portion 150 and the output portion 160 form an integral structure, thereby forming the second connector 140.

[0062] In some embodiments, the second connector 140 is coupled to the second portion of the tubing to allow the second portion of the tubing to be connected and / or disconnected from the first connector 102. The second connector 140 may include a first end 151 and a second end 153. The first end 151 may be configured to be coupled to the first connector 102, and the second end 153 may be coupled to the tubing (e.g., the second portion of the tubing). In some embodiments, a portion of the tubing may be coupled or engaged with the second end 153 of the second connector 140. The second connector 140 may be in fluid communication with the tubing via the second end 153 to allow fluid to pass through the second connector 140. In some embodiments, the first end 151 may have a flat surface to allow the clinician to easily clean and disinfect the first end 151. The first end 151 may be fluidly connected to the second end 153. The first end 151 and the second end 153 may be arranged along the longitudinal length of the second connector 140. For example, the first end 151 and the second end 153 may be arranged along the central axis AA. The first end 151 and / or the second end 153 may include an opening to allow the first end 151 and / or the second end 153 to be in fluid communication with one or more components (e.g., a fitting, a connector, a valve, a collar, an accessory, etc.). For example, the first end 151 may include an opening 156 and the second end 153 may be coupled to a tube to allow fluid communication through the second connector 140.

[0063] In some embodiments, the fluid can flow out or flow through the second connector 140 via the second end 153 disposed opposite the first end 151. The flow path through the second connector 140 can have a straight fluid passage to make flushing easier and reduce the risk of hemolysis. Optionally, the second connector 140 may include features (e.g., raised features, gripping features) disposed on the outer surface of the second connector 140 to allow the clinician to more easily operate or manipulate the second connector 140. Some embodiments of the second connector 140 can provide a connector that is compatible with connectors of other parts of the fluid delivery system. The second connector 140 can be substantially cylindrical in shape.

[0064] In some embodiments, the second connector 140 includes a coupling portion 150 disposed near the first end 151 and an output portion 160 disposed near the second end 153. The output portion 160 can be configured to be coupled to a portion of the tubing to allow the second connector 140 to be in fluid communication with the portion of the tubing and to be in fluid communication with the patient via the portion of the tubing. For example, the output portion 160 can include a channel 164 to allow fluid flow within the output portion 160. The channel 164 can be disposed within the output portion 160 and extend the length of the output portion 160. The channel 164 can include an outlet 170. The outlet 170 can be disposed at the distal end of the channel 164 and can be disposed near the second end 153.

[0065] In some embodiments, the coupling portion 150 is disposed opposite the output portion 160 and is configured to couple to the first connector 102 to secure the first connector 102 to the second connector 140. For example, the coupling portion 150 can be configured to couple with a portion of the first connector 102 to secure and couple the first connector 102 to the second connector 140, as described below. In some embodiments, the coupling portion 150 is sized and shaped to be received by the first connector 102 and disposed within the first connector, such as within the mating portion 130. For example, the mating portion 130 can be configured to receive and secure the coupling portion 150 to secure the second connector 140 to the first connector 102. In some embodiments, the mating portion 130 receives the coupling portion 150 such that the coupling portion 150 extends through the second end portion 103.

[0066] In some embodiments, the output portion 160 includes a channel 164 and a tube 162. The channel 164 can extend through the tube 162. The channel 164 can include a proximal end 163, which can include an opening 176. The channel 164 can include an outlet 170, which can be arranged opposite to the opening 176 and the proximal end 163. The channel 164 can allow the outlet 170 to be in fluid communication with the opening 176, so that the fluid entering the channel 164 at the opening 176 (e.g., from the first connector 102) flows through the channel 164 and out of the outlet 170. The tube 162 can be configured to receive and couple to a portion of the tubing (e.g., a second portion of the tubing). In some embodiments, the tube 162 includes a groove 169 disposed on the inner surface of the tube 162. The groove 169 can be configured to help secure a portion of the tubing in the tube 162. For example, a portion of a tubing may be inserted into the tube 162 , and the groove 169 may be configured to help prevent the portion of the tubing from being accidentally removed or separated from the second connector 140 .

[0067] The coupling portion 150 may be disposed closer to the first end 151 than the output portion 160. The coupling portion 150 may include an opening 156. In some embodiments, the opening 156 is disposed closer to the first end 151. The coupling portion 150 may include an interior space 154 disposed within the coupling portion 150. In some embodiments, the coupling portion 150 includes a biasing element 152 and a valve 165 disposed within the interior space 154. In some embodiments, the valve 165 is disposed closer to the first end 151 than the biasing element 152. The biasing element 152 may be a spring coupled to one end of the valve 165. The biasing element 152 may be a spring or a spring-like structure to allow the biasing element 152 to be in a compressed state or an expanded state.

[0068] The biasing element 152 may have a first end 153 and a second end 155. The first end 153 of the biasing element 152 may be disposed closer to the first end 151 than the second end 155. The biasing element 152 may be coupled to a valve 165. In some embodiments, the valve 165 is coupled to the first end 153 of the biasing element 152. The valve 165 may have a first end 161 and a second end 167. The second end 167 may be disposed opposite the first end 161. In some embodiments, the first end 161 and the second end 167 have substantially flat faces or surfaces. The surface of the first end 161 may be substantially parallel to the surface of the second end 167. In some embodiments, the length and / or width of the surface of the first end 161 is less than the length and / or width of the surface of the second end 167. In some embodiments, the valve 165 is coupled to the biasing element 152 at the second end 167.

[0069] In some embodiments, the biasing element 152 in the expanded state causes the valve 165 to be in the expanded state and to extend at least partially through the opening 156. In some embodiments, when the valve 165 and the biasing element 152 are in the expanded state, the first end 161 is disposed through the opening 156. For example, when the valve 165 and the biasing element 152 are in the expanded state, the opening 156 can be disposed between the first end 161 and the second end 167.

[0070] In some embodiments, the channel 164 extends through the output portion 160 into the coupling portion 150. For example, the channel 164 can extend from an area proximate the second end 153 into the interior space 154. In some embodiments, the opening 176 is disposed within the interior space 154. The second end 155 of the biasing element 152 can be coupled to the channel 164 such that the opening 176 is disposed proximate the second end 155.

[0071] The biasing element 152 can have a compressed state and an expanded state. For example, the biasing element 152 can be configured to compress (e.g., shorten in length) or expand (e.g., increase in length). The biasing element 152 can be biased to the expanded state. The biasing element 152 can be substantially similar to the biasing element 119. In some embodiments, the biasing element 152 and the biasing element 119 are the same. Alternatively, the biasing element 119 and the biasing element 152 can have different lengths, different stiffnesses, or can be made of different materials.

[0072] In the compressed state, the first end 153 is disposed proximate to the second end 155 and the opening 176 of the passage 164. In the expanded state, the first end 153 can be disposed away from the second end 155. Because the valve 165 is coupled to the first end 153, the valve 165 is disposed proximate to the second end 155 and the opening 176 in the compressed state compared to when the biasing element 152 is in the expanded state. In some embodiments, when the biasing element 152 is in the expanded state, the valve 165 is disposed away from the second end 155 and is at least partially disposed within and / or through the opening 156. The valve 165 is at least partially disposed within the opening 156 so that the opening 156 is sealed, thereby preventing any fluid from flowing into or out of the opening 156 (e.g., leaking). For example, the biasing element 152 can be in the expanded position so that the valve 165 is at least partially disposed within the opening 156. The valve 165 disposed within and / or through the opening seals the opening 156 and prevents liquid from entering or flowing out of the second connector 140 (e.g., leaking). In some embodiments, the opening 156 is sized and shaped to match the profile of the valve 165, thereby allowing the valve 165 to seal the opening 156. The valve 165 can have any shape configured to seal the opening 156. In some embodiments, the second connector 140 allows a one-way flow of fluid. For example, the second connector 140 and / or the valve 165 can allow fluid to flow into the opening 156, but not allow fluid to flow out of the opening 156.

[0073] In some embodiments, the first end 153 of the biasing element 152 is coupled to a valve 165. The valve 165 can be disposed within the interior space 154 and can be configured to extend at least partially through the opening 156. In some embodiments, the valve 165 is configured to seal the opening 156 when the biasing element 152 is in the expanded state. For example, the valve 165 can be completely disposed within the opening 156 and extend at least partially through the opening 156 to seal the opening 156.

[0074] In some embodiments, valve 165 is pushed or pressure / force is applied to valve 165 via another structure to place biasing element 152 in a compressed state, thereby enabling fluid to flow into and / or out of opening 156. When the pressure / force is removed from valve 165, biasing element 152 can return to an expanded state, thereby causing valve 165 to be at least partially disposed within opening 156, thereby sealing opening 156 and preventing fluid from flowing into and / or out of opening 156 (e.g., leaking).

[0075] In some embodiments, when the biasing element 152 is in a compressed state and the valve 165 does not seal the opening 156, the opening 156 is in fluid communication with the passage 164. For example, a fluid can flow into the opening 156 and into the interior space 154. The fluid can flow from the interior space 154 into the passage 164 through the opening 176. The fluid can then flow through the passage 164 via the tube 162 and the groove 169 into the tubing portion coupled to the output portion 160. The biasing element 152 in the expanded position causes the valve 165 to seal the opening 156, and the opening 156 is no longer in fluid communication with the passage 164.

[0076] refer to Figure 2 , the first connector 102 can be configured to be coupled to the second connector 140. In some embodiments, coupling the first connector 102 to the second connector 140 causes the inlet 115 to be in fluid communication with the outlet 170. For example, coupling the first connector 102 to the second connector 140 causes the interior space 117 to be in fluid communication with the interior space 154. In some embodiments, coupling the first connector 102 and the second connector 140 causes the mating portion 130 to receive most or at least a portion of the coupling portion 150. For example, the mating portion 130 can include a channel 134 configured to receive and secure the coupling portion 150. The mating portion 130 can include one or more grooves 136 configured to secure the coupling portion 150 within the mating portion 130.

[0077] The mating portion 130 can be configured to secure the second connector 140 to the first connector 102, thereby preventing the second connector 140 from being inadvertently separated from the first connector 102. For example, the mating portion 130 can be configured to secure the second connector 140 into the mating portion 130 via a friction fit coupling portion 150. In some embodiments, the second connector 140 is coupled and secured to the first connector 102 by friction fit or snap fit coupling portion 150 into the mating portion 130. The coupling portion 150 can be disposed and secured into the mating portion 130 via a snap fit, a friction fit, a magnet, external and internal threads, an adhesive, or any other type of securing element. For example, the coupling portion 150 can be disposed and secured into the mating portion 130 by snap fit, friction fit, or threaded engagement of the coupling portion 150 into the mating portion 130.

[0078] The groove 136 can help secure the coupling portion 150 within the mating portion 130. In some embodiments, the coupling portion 150 can be inserted through the passage 134 so that the opening 156 of the second connector 140 is disposed proximate to the opening 110 of the first connector 102. In some embodiments, when the first connector 102 is coupled to the second connector 140, the opening 110 contacts or abuts the opening 156.

[0079] The coupling portion 150 can include a ring 157 configured to prevent the second connector 140 from being over-inserted into the mating portion 130. For example, the ring 157 can be a protruding ring around the coupling portion 150 that can surround an outer edge (e.g., 133) of the channel 134 when the first connector 102 is coupled to the second connector 140. The ring 157 can prevent the second connector 140 from being inserted through the opening 110 of the first connector and / or can prevent the first connector 102 from being inserted through the opening 156 of the second connector.

[0080] When the first connector 102 is not coupled to the second connector 140, the valve 104 can extend into and through the opening 110, and the valve 165 can extend into and through the opening 156. In some embodiments, when the biasing element 119 and the biasing element 152 are respectively in the expanded state, both the valve 104 and the valve 165 can be in the expanded state. The valve 104 in the expanded state causes the valve 104 to seal the opening 110 by extending into and through the opening. The valve 165 in the expanded state causes the valve 165 to seal the opening 156 by extending into and through the opening. The biasing element 119 and the biasing element 152 in the compressed state cause the valve 104 and the valve 165 to be in the compressed state, respectively. When the valve 104 is in the compressed state, the valve 104 no longer seals the opening 110, and when the valve 165 is in the compressed state, the valve 165 no longer seals the opening 156. In some embodiments, when first connector 102 is separated from second connector 140 (e.g., coupling assembly 100 is in the second configuration), valve 104 seals opening 110 and valve 165 seals opening 156 such that no fluid flows out of opening 110 and opening 156. Valve 104 (and biasing element 119) and valve 165 (and biasing element 152) can transition from an expanded state to a compressed state due to a force applied to each of valve 104 and valve 165.

[0081] In some embodiments, when the first connector 102 is coupled to the second connector 140 (e.g., the coupling assembly 100 is in the first configuration), the valve 104 exerts a force on the valve 165 such that the valve 104 (and the biasing element 119) are in a compressed state, and the valve 165 exerts a force on the valve 104 such that the valve 165 (and the biasing element 152) are in a compressed state. In other words, when the first connector 102 is coupled to the second connector 140, the valve 104 and the valve 165 exert a force on each other such that both the valve 104 and the valve 165 are in a compressed state and allow the opening 110 to be in fluid communication with the opening 156.

[0082] In some embodiments, the first connector 102 is coupled to the second connector 140 such that the opening 110 is disposed against or near the opening 156. Due to the valve 104 extending through the opening 110 and the valve 165 extending through the opening 156, when the opening 110 is disposed against or near the opening 156, such as when the first connector 102 is coupled to the second connector 140, the valve 104 and the valve 165 can apply a force (e.g., pressure) to each other such that the valve 104 and the valve 165 are in a compressed state. The valve 104 and the valve 165 in the compressed state make the opening 110 and the opening 156 no longer sealed, thereby allowing the fluid to flow out of the opening 110 and into the opening 156.

[0083] In practice, the second connector 140 is coupled to the first connector 102 by inserting the coupling portion 150 into the mating portion 130. The coupling portion 150 can be inserted into the mating portion 130 until the opening 156 abuts the opening 110 and / or until the outer edge (e.g., edge 133) of the channel 134 abuts the ring 157. The opening 156 adjacent to the opening 110 causes the valve 104 to contact the valve 165 because the valve 104 at least partially extends through the opening 110 and the valve 165 at least partially extends through the opening 156. The valve 104 contacts the valve 165 so that each applies a force or pressure to each other. Since the valve 104 is coupled to the biasing element 119 and the valve 165 is coupled to the biasing element 152, when a force or pressure is applied, each of the valve 104 and the valve 165 can be transformed from an expanded state to a compressed state, thereby causing the opening 110 and the opening 156, respectively, to no longer be sealed. Since opening 110 abuts opening 156 and opening 110 and opening 156 are no longer sealed by valves 104 and 165, respectively, opening 110 can be in fluid communication with opening 156. In some embodiments, opening 110 is in fluid communication with opening 156 such that fluid can flow from first connector 102 to second connector 140 through opening 110 and opening 156.

[0084] refer to Figure 5 The opening 15 and the opening 110 in fluid communication form a fluid passage between the first connector 102 and the second connector 140 (by Figure 5 156). For example, when the first connector 102 is coupled to the second connector 140, the opening 110 can be in fluid communication with the opening 156, so that a fluid passage is formed between the first connector 102 and the second connector 140. When the coupling assembly 100 is in a first configuration (e.g., when the first connector 102 is coupled to the second connector 140), a fluid passage can be formed. In the first configuration, a fluid can flow into the first connector 102 via the inlet 115. The fluid can then flow within the interior space 117 of the body 116, around the biasing element 119 and the valve 104 (which can be in a compressed state) and through the opening 110. The fluid can then flow from the opening 110 through the opening 156 into the interior space 154 around the valve 165 and the biasing element 152. The fluid can flow from the interior space 154 into the opening 176 and out of the outlet 170 through the channel 164 to a portion of the tubing coupled to the output portion 160.

[0085] Figure 6 According to various aspects of the present disclosure Figure 1 A cross-sectional side view of a coupling assembly of claim 1 wherein the first connector is separated from the second connector.

[0086] refer to Figure 6, the coupling assembly 100 can be configured to be in a second configuration. In the second configuration, the first connector 102 is separated from the second connector 140. In the second configuration, the biasing element 119 and the valve 104 and the valve 165 and the biasing element 152 return to their biased expanded states, and the fluid passage between the first connector 102 and the second connector 140 is interrupted. In some embodiments, the biasing element 119 and the valve 104 return to the expanded state so that the opening 110 is sealed and prevents the fluid from flowing into / out of the first connector 102. In some embodiments, the biasing element 152 and the valve 165 return to the expanded state so that the opening 156 is sealed by the valve 165, thereby preventing the fluid from flowing into / out of the second connector 140. By separating the first connector 102 from the second connector 140, the coupling assembly 100 can be converted from the first configuration to the second configuration.

[0087] In some embodiments, the first connector 102 is configured to be separated from the second connector 140 due to a disconnection event caused by a pull-out force. For example, the pull-out force (e.g., force F) can be applied to the first connector 102 by being applied directly to the first connector 102 or indirectly to the first connector 102, such as by being applied to a pipe coupled to the first connector 102. The pull-out force can cause the first connector 102 to move axially away from the second connector 140 along the central axis AA, thereby separating the first connector 102 from the second connector 140.

[0088] In some embodiments, when the force F exceeds a predetermined threshold force, the first connector 102 is separated from the second connector 140. For example, if the force F is less than the predetermined threshold force, the first connector 102 may not be separated from the second connector 140. The predetermined threshold force prevents unintentional or accidental separation based on small forces or movements. The predetermined threshold force can be based on the flexibility and / or stiffness of the mating portion 130 and / or the groove 136. For example, the higher the stiffness of the mating portion 130 and / or the groove 136, the higher the predetermined threshold force. In some embodiments, the mating portion 130 includes a groove 136, which is arranged at different positions within the channel 134 to increase the friction force on the coupling portion 150, thereby preventing the coupling portion 150 (and the second connector 140) from accidentally separating from the first connector 102. For example, multiple grooves 136 create multiple positions or snap positions for fixing the coupling portion 150 within the mating portion 130. Multiple positions allow different forces required to separate the second connector 140 from the first connector 102. Multiple positions and different forces may be required based on the desired use of the coupling assembly 100. In some embodiments, when the extraction force exceeds a predetermined threshold force, the mating segment 130 and / or the groove 136 may be unable to retain the coupling segment 150 within the mating segment 130, thereby allowing the first connector 102 to separate from the second connector 140.

[0089] In some embodiments, the predetermined threshold force is approximately 4 pounds (lb). The predetermined threshold force can be from about 1 lb to about 8 lb, about 3 lb to about 7 lb, about 4 lb to about 6 lb, or greater than 8 lb. For example, a patient can insert a needle / catheter into their skin, and the needle / catheter can be coupled to the first connector 102 or the second connector 140. The patient may leave the infusion pump or accidentally pull the fluid line coupled to the first connector 102 or the second connector 140, and the force exceeds 4 lb, the first connector 102 can be automatically released or separated from the second connector 140 to effectively close the fluid passage between the first connector 102 and the second connector 140, as described herein.
