[0034] The disclosed coupler assembly includes a first connector and a second connector. The first connector is configured to couple 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 second connector. In the second configuration, the first connector is uncoupled from the second connector.

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

[0036] In some embodiments, the second connector is configured to uncouple from the first connector. The second connector can be sterilized (e.g., via sterilized cloth or a sterilization device) or replaced with a new, sterilized connector to prevent infection or contamination that can occur if the second connector is reused without being sterilized. In some embodiments, the second connector is configured to uncouple based on a force that exceeds a predetermined threshold force. When a force (such as an extraction force) that exceeds the predetermined threshold force is applied to the second connector, the second connector can uncouple from the first connector. The extraction force can be a force that is generated along a longitudinal axis of the coupler assembly and / or the second connector. In some embodiments, the extraction force is caused by dragging or pulling the second portion of the tubing set that is coupled to the second connector. Alternatively, the extraction force applied to the second connector can be caused by dragging or pulling the first portion of the tubing set that is coupled to the first connector and / or the first connector.

[0037] In some embodiments, once the first connector is uncoupled from the second connector, the second connector is configured to recouple to the first connector. For example, once the second connector is uncoupled from the first connector, the first connector can be configured to allow recoupling to the second connector after a decoupling event occurs.

[0038] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology can be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. Like reference numbers can designate like elements throughout. Reference numbers accompanied by an accompanying letter suffix can designate variations of the element that differs from the element without the suffix letter. Reference numbers accompanied by an accompanying letter suffix can designate variations of the element that differs from the element without the suffix letter.

[0039] While the following description is directed to the use of the disclosed couplings to connect medical fittings for administering medical fluids, it should be understood that the description is merely an example of use and does not limit the scope of the claims. Various aspects of the disclosed couplings can be used in any application where securement of connections of various tubing and fittings is desired.

[0040] The disclosed coupling assemblies overcome several challenges found with certain conventional couplings. One challenge with certain conventional couplings is that certain conventional couplings can be inappropriately secured. Further, during use, certain conventional couplings can be designed to release or dislodge in response to relatively low pull-out forces. For example, certain conventional couplings can release in response to pull-out forces experienced by a patient rolling over in bed, a patient grabbing on to a tube or tubing on a bed rail, moving a patient to a different bed, a pediatric patient fidgeting and / or a disoriented adult patient pulling out their tubing. In fact, the 2017 Annual Scientific Meeting report of the Association for Vascular Access (AVA) stated that the dislodgement rate for 1000 patients with peripheral IV catheters was 10%, which equates to approximately 33 million dislodgements per year in the United States alone. Because accidental or inadvertent dislodgement of a tube, catheter, or fitting can interrupt administration of medical fluids, use of certain conventional couplings is undesirable.

[0041] Accordingly, in accordance with the present disclosure, it is advantageous to provide couplings and coupling / connector assemblies as described herein that allow for improved securement of fittings or connectors. The disclosed couplings and coupling / connector assemblies are configured as described herein in order to permit secure retention of a first connector while allowing for separation after a breakaway event.

[0043] Referring to Figures 1-3 The coupler assembly 100 allows fluid, such as medical fluid, to flow from a fluid source 500 to a patient end 600 by releasably coupling a portion of tubing or a line in fluid communication with another portion of tubing or a line. The coupler assembly 100 can include a first connector 102 and a second connector 140. The first connector 102 can be configured to couple to the second connector 140. In the depicted example, portions of tubing can be terminated with connectors / valves, such as the first connector 102 and / or the second connector 140. In some embodiments, fluid from the fluid source 500 flows through the coupler assembly 100 to the patient end 600. A cannula or needle can be inserted into a 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, decoupling the first connector 102 from the second connector 140 interrupts or prevents flow from the fluid source 500 to the patient end 600.

[0044] In some embodiments, the coupler assembly 100 includes a central axis A-A, and the first connector 102 and the second connector 140 are coupled in series along the central axis A-A. The first connector 102 and / or the second connector 140 can allow for connection and / or disconnection of tubing to allow for selective fluid communication therebetween. The central axis A-A can extend longitudinally along the length of the first connector 102 and the second connector 140.

[0045] The coupler assembly 100 can have a first configuration and a second configuration. In the first configuration, the first connector 102 is coupled to the second connector 140. In the second configuration, the first connector 102 is decoupled from the second connector 140. In some embodiments, the coupler assembly 100 transitions from the first configuration to the second configuration in response to a decoupling event. The decoupling event can occur when an extraction force is applied to the second connector 140 or the first connector 102. In some embodiments, an extraction force is applied to the second connector 140, causing axial movement of the second connector 140 relative to the first connector 102. In some embodiments, axial movement of the second connector 140 relative to the first connector 102 is caused when the extraction force applied to the second connector 140 exceeds a predetermined threshold force.

[0046] In some embodiments, the first connector 102 is coupled to a first portion of a tubing set to allow the first portion of the tubing set to connect and / or disconnect with the second connector 140. The first connector 102 can include a first end 101 and a second end 103. The first end 101 can be coupled to a tubing set (e.g., a first portion of the tubing set), and the second end 103 can be configured to be coupled to the second connector 140. In some embodiments, a portion of the tubing set can be coupled or engaged with the first end 101 of the first connector 102. The first connector 102 can be in fluid communication with the tubing set via the first end 101 to allow fluid to pass through the first connector 102. In some embodiments, the first end 101 can have a flat surface to allow a clinician to easily clean and sterilize the first end 101. The first end 101 can be fluidly connected with the second end 103. The first end 101 and the second end 103 can be disposed along a longitudinal length of the first connector 102. For example, the first end 101 and the second end 103 can be disposed along a central axis A-A. The first end 101 and / or the second end 103 can 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 tubing set, a connector, a valve, a collar, an accessory, etc.). For example, the first end 101 can be coupled to a tube, and the second end 103 can include an opening to allow fluid communication through the first connector 102. In some embodiments, the first connector 102 includes a valve 104 configured to be disposed in the first connector 102.

[0047] In some embodiments, fluid can exit 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 path to make flushing easier and reduce the risk of hemolysis. Optionally, the first connector 102 can include a feature (e.g., a raised feature, a gripping feature) 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 is compatible with connectors of other portions of a fluid delivery system. The first connector 102 can be substantially cylindrical in shape.

[0048] In some embodiments, the first connector 102 includes a tubing portion 107 and a mating portion 105. The tubing portion 107 can be disposed at the first end 101, and the mating portion 105 can be disposed at the second end 103. The tubing portion 107 can be configured to be coupled to a portion of a tube, allowing the first connector 102 to be in fluid communication with the portion of the tube. For example, the tubing portion 107 can include a channel 116 to allow fluid flow within the tubing portion 107. The channel 116 can be disposed within the tubing portion 107 and extend the length of the tubing portion 107.

[0049] In some embodiments, the mating portion 105 is disposed opposite the tubing portion 107, and the second connector 140 is configured to be coupled to the mating portion 105 to secure the first connector 102 to the second connector 140. For example, the mating portion 105 can include a groove 109 configured to receive a portion of the second connector 140 to secure the second connector 140 to the first connector 102, as described below. The groove 109 can be disposed on the mating portion 105 proximate the second end 103. In some embodiments, the groove 109 is configured to receive and engage a portion of the second connector 140 to secure the second connector 140 to the first connector 102. The groove 109 can be disposed circumferentially around the mating portion 105. The groove 109 can be continuously disposed circumferentially around the mating portion 105. In some embodiments, the groove 109 is disposed circumferentially around the mating portion 105 in a repeating pattern or at predetermined locations.

[0050] In some embodiments, the first connector 102 includes a body 111 and the valve 104. The body 111 can extend from the tubing portion 107. For example, the body 111 can extend away from the tubing portion 107 toward the second end 103. In some embodiments, the body 111 and the tubing portion 107 are formed of a unitary structure. Alternatively, the body 111 can be fixedly or removably coupled to the tubing portion 107. In some embodiments, the body 111 includes a channel 113. The channel 113 can be disposed within the body 111 and can be in fluid communication with the channel 116 of the tubing portion 107. For example, the tubing portion 107 can be coupled to the fluid source 500 via a portion of a tube, allowing fluid to flow from the fluid source 500 and into the channel 116. Fluid can flow from the channel 116 into the channel 113 of the body 111. In some embodiments, the body 111 is disposed between the tubing portion 107 and the mating portion 105. The body 111 can be coupled to the tubing portion 107 and the mating portion 105. In some embodiments, the tubing portion 107, the body 111, and the mating portion 105 form a unitary structure.

[0051] In some embodiments, the body 111 includes a valve 104. The valve 104 can include a distal end 117. The valve 104 can be disposed within the body 111 and can be disposed proximate the second end 103. In some embodiments, the valve 104 is disposed between the tubing portion 107 and the second end 103. The valve 104 can be in fluid communication with the channel 113, which can be in fluid communication with the channel 116.

[0052] In some embodiments, the valve 104 extends at least partially into the second connector 140 when the second connector 140 is coupled to the first connector 102. For example, the distal end 117 can be at least partially disposed within the second connector 140 when the second connector 140 is coupled to the first connector 102. The valve 104 (e.g., the distal end 117) being at least partially disposed within the second connector 140 when the second connector 140 is coupled to the first connector 102 can result in the first connector 102 being in fluid communication with the second connector 140. In other words, a fluid path is formed between the first connector 102 and the second connector 140 via the channel 113 and the valve 104 when the second connector 140 is coupled to the first connector 102. In some embodiments, the valve 104 is configured to be in an open position when the second connector 140 is coupled to the first connector 102. The valve 104 can be configured to be in a closed configuration when the second connector 140 is decoupled from the first connector 102. The valve 104 being in the closed configuration can result in the fluid path through the channel 113 and the valve 104 being terminated, thereby preventing fluid from flowing out of the first connector 102. The valve 104 can be in the open position when the second connector 140 is coupled to the first connector 102 to allow fluid to flow from the first connector 102 to the second connector 140 through the channel 113 and the valve 104.

[0053] In some embodiments, the second portion of the tubing is terminated by the second connector 140 to allow the second portion of the tubing to be connected and / or disconnected from the first connector 102. The second connector 140 can include a first end 141 and a second end 143 disposed opposite the first end 141. The first end 141 can include a housing 144 and the second end 143 can include a connection portion 145 that can be disposed opposite the housing 144. In some embodiments, a portion of the tubing is coupled or engaged with the connection portion 145 of the second connector 140. In some embodiments, the connection portion 145 includes a threaded connection to facilitate coupling with the tubing. For example, the connection portion 145 can include a connection portion 145 that is configured to be coupled to a portion of the tubing.

[0054] In some embodiments, the housing 144 includes features (e.g., threads) that allow the second connector 140 to mate with the first connector 102. The housing 144 can fit together with or otherwise engage the second end 103 of the first connector 102 to allow fluid communication between the first connector 102 and the second connector 140 and the portions of tubing coupled to the first and second connectors. As can be appreciated, the first connector 102 and the second connector 140 can be coupled and decoupled to permit fluid communication as desired. The first connector 102 can be detachably coupled with the second connector 140 to provide a needleless connection. Advantageously, the first connector 102 can be paired with the second connector 140 to form a leak-free closed system allowing for the delivery of various medications or fluids.

[0055] In some embodiments, the second connector 140 includes a connection portion 145 disposed opposite the housing 144. The housing 144 can extend from the connection portion 145. The connection portion 145 can include a channel 149 disposed within the connection portion 145. The channel 149 can include an opening 151 that can be disposed between the first end 141 and the second end 143. The opening 151 can be in fluid communication with the channel 149 such that liquid entering the opening 151 flows into the channel 149 and through the connection portion 145. The channel 149 can also include an outlet 155.

[0056] In some embodiments, the connection portion 145 includes the outlet 155. The outlet 155 can be configured to allow fluid to exit the coupler assembly 100. In some embodiments, when the first connector 102 is coupled to the second connector 140, fluid enters the first connector 102 via the channel 116, flows through the fluid path formed between the first connector 102 and the second connector 140, and exits the second connector 140 via the outlet 155.

[0057] The connection portion 145 can be configured to be coupled to a portion of tubing (e.g., tubing coupled to the patient end 600) such that the channel 149 is in fluid communication with the portion of tubing. In some embodiments, an inner surface of the connection portion 145 includes threads to couple or mate with a portion of tubing to allow the second connector 140 to be in fluid communication with the portion of tubing.

[0058] The housing 144 can extend from the connection portion 145 toward the first end 141. In some embodiments, the passage 149 extends through the housing 144. The housing 144 can include a cavity 157 disposed within the housing 144. The cavity 157 can be an interior space within the housing 144. In some embodiments, when the second connector 140 is coupled to the first connector 102, the valve 104 is at least partially disposed within the cavity 157 of the second connector 140. This places the first connector 102 in fluid communication with the second connector 140 to form a fluid path between the first connector 102 and the second connector 140. When the first connector 102 is coupled to the second connector 140, the valve 104 can be at least partially disposed within the opening 151 such that the valve 104 at least partially extends through the opening 151 into the cavity 157. In some embodiments, the second connector 140 is coupled to the mating portion 105 of the first connector 102.

[0059] Referring to Figures 2-3 When the coupler assembly 100 is in the first configuration (e.g., when the first connector 102 is coupled to the second connector 140), a fluid path is formed. In the first configuration, fluid can flow into the first connector 102 via the passage 116 and into the body 111. The fluid can then flow through the fluid valve 104 into the cavity 157. The fluid can then flow through the passage 149 out of the second connector 140 via the outlet 155.

[0061] In some embodiments, the second connector 140 is configured to couple and decouple with the first connector 102. For example, when the first connector 102 is coupled to the second connector 140, the second connector 140 can decouple from the first connector 102 in response to a decoupling event. The second connector 140 can be configured to decouple from the first connector 102 in response to a pull-out force exceeding a predetermined threshold.

[0062] In some embodiments, the second connector 140 includes a ring 146. The ring 146 can extend outwardly from the housing 144. The ring 146 can be a ring disposed about the housing 144 (e.g., the opening 151) and can be configured to engage with the first connector 102 to couple the second connector 140 to the first connector 102. The ring 146 can include an outer perimeter of the second connector 140. In some embodiments, the diameter of the ring 146 is the largest diameter of the second connector 140. In some embodiments, the ring 146 is configured to removably couple to the first connector 102. For example, the ring 146 can allow the second connector 140 to couple to the first connector 102 and can allow the second connector 140 to decouple from the first connector 102 in response to a disconnect event.

[0063] In some embodiments, the ring 146 is concentric with the opening 151. For example, a center of the ring 146 can be a center of the opening 151. In some embodiments, the central axis A-A extends through the center of the opening 151 and the ring 146 when the second connector 140 is coupled to the first connector 102. The ring 146 can have a diameter that is greater than a diameter of the opening 151. In some embodiments, the ring 146 is configured to engage with one or more grooves 109 of the first connector 102 to couple the second connector 140 to the first connector 102.

[0064] In some embodiments, the second connector 140 includes a gap 153. The gap 153 can be a space between the ring 146 and the opening 151. In some embodiments, at least a portion of the first connector 102 (e.g., the mating portion 105) is disposed within the gap 153 when the first connector 102 is coupled to the second connector 140.

[0065] In some embodiments, the ring 146 includes one or more relief cuts or cuts 147. The cuts 147 can be configured to divide the ring 146 into a plurality of flanges 148. For example, the ring 146 can include three cuts 147 that divide the ring 146 into three flanges 148a, 148b, and 148c. In some embodiments, the ring 146 includes one, two, four, five, six, or more than six cuts 147. The ring 146 can include a plurality of cuts 147 to divide the sidewall into two, four, five, six, or more than six flanges 148. In some embodiments, the cuts 147 are configured to extend completely through the ring 146.

[0066] Reference Figure 4AThe second connector 140 can include one or more ridges 160. The ridges 160 can extend from the ring 146. In some embodiments, the ridges 160 extend radially inward from the ring 146. For example, the ridges 160 can extend toward the opening 151. The ridges 160 can be configured to engage with the grooves 109 to secure the second connector 140 to the first connector 102. In some embodiments, the cutouts 147 divide the ridges 160 into multiple ridges 160, similar to the flanges 148. Each flange 148 can include its own ridge 160 that is configured to engage with a groove 109 of the first connector 102.

[0067] In some embodiments, the cutouts 147 allow the flanges 148 to move relative to one another. For example, the cutouts 147 can allow adjacent flanges 148 to flex and bend radially outward when the second connector 140 is coupled to and / or decoupled from the first connector. In some embodiments, the cutouts 147 are configured to relieve strain on the material during injection molding of the second connector 140. For example, the cutouts 147 can allow for increased tolerances when forming the second connector 140. The cutouts 147 can allow each flange 148 to move independently of one another (e.g., flex and deflect).

[0068] During coupling of the second connector 140 to the first connector 102, the first connector 102 is inserted into the gap 153 such that the ridges 160 of the flanges 148 engage with the grooves 109 of the first connector 102. The flanges 148 can flex and bend radially outward due to the cutouts 147 to allow the ridges 160 to engage with the grooves 109. The flanges 148 can be biased radially inward such that once the ridges 160 are disposed within the grooves 109, the flanges 148 return to their biased radially inward position to secure the second connector 140 to the first connector 102.

[0069] In some embodiments, the cutouts 147 are configured to allow the second connector 140 to decouple from the first connector 102 in response to a decoupling event (e.g., a pull-out force). For example, in response to a pull-out force, the flanges 148 can flex radially outward causing the ridges 160 to no longer be disposed within the grooves 109, allowing the second connector 140 to decouple from the first connector 102. In some embodiments, the cutouts 147 can have a width of 0.5 mm to 1 mm. The width of the cutouts 147 can be about 0.25 mm to about 3.0 mm, about 0.5 mm to about 2.5 mm, about 0.75 mm to about 2.0 mm, about 1.0 mm to about 1.5 mm, greater than 3.0 mm, or less than 0.25 mm. In some embodiments, the flanges 148 are the weakest link in the coupling assembly 100. For example, the flanges 148 can be the weakest coupling component in the coupling assembly 100, allowing the second connector 140 to decouple from the first connector 102 via the flanges 148.

[0070] In some embodiments, the coupler assembly 100 is in the first configuration when the flange 148 of the second connector 140 is coupled to or disposed within the groove 109 of the mating portion 105. The ridge 160 can be disposed within the groove 109, which prevents axial movement of the second connector 140 relative to the first connector 102, thereby securing the second connector 140 to the first connector 102.

[0071] The coupler assembly 100 can be configured to be in a second configuration. In the second configuration, the second connector 140 is decoupled from the first connector 102. In the second configuration, the valve 104 is closed and the fluid path between the first connector 102 and the second connector 140 is interrupted. In some embodiments, the return of the valve 104 to the closed position prevents fluid from flowing out of the first connector 102. The coupler assembly 100 can transition from the first configuration to the second configuration by decoupling the second connector 140 from the first connector 102.

[0072] In some embodiments, the second connector 140 is configured to decouple from the first connector 102 due to a decoupling event caused by an extraction force. For example, the extraction force (e.g., force F) can be applied to the second connector 140 by being applied directly to the second connector 140 or indirectly to the second connector 140, such as to a pipe coupled to the second connector 140 and / or the first connector 102. The extraction force can cause the second connector 140 to move axially along the central axis A-A away from the first connector 102, thereby decoupling the second connector 140 from the first connector 102.

[0073] In some embodiments, the second connector 140 decouples from the first connector 102 when the force F exceeds a predetermined threshold force. For example, if the force F is less than the predetermined threshold force, the second connector 140 can not decouple from the first connector 102. The predetermined threshold force prevents inadvertent or accidental decoupling based on minor forces or movements. The predetermined threshold force can be based on the flexibility and / or stiffness of the flange 148 and / or the ridge 160. For example, the higher the stiffness of the flange 148, the higher the predetermined threshold force. In some embodiments, the number and / or width of the cutouts 147 determines the predetermined threshold force. For example, an increase in the number of cutouts 147 or an increase in the width of the cutouts 147 can decrease the predetermined threshold force required. In some embodiments, an increase in the number of cutouts 147 or an increase in the width of the cutouts 147 decreases the contact area between the second connector 140 and the first connector 102 (e.g., the ridge 160 and the groove 109), thereby decreasing the predetermined threshold force required to decouple the second connector 140 from the first connector 102.

[0074] In some embodiments, the predetermined threshold force is about 4 pounds (lb). The predetermined threshold force can be from about 1 pound to about 8 pounds, about 3 pounds to about 7 pounds, about 4 pounds to about 6 pounds, or greater than 8 pounds. For example, a patient can have a needle / catheter inserted into their skin, and the needle / catheter can be coupled to the first connector 102 or the second connector 140. The patient can walk away from the infusion pump or accidentally pull on a fluid line coupled to the first connector 102 or the second connector 140, and the force exceeds 4 pounds, the second connector 140 can automatically release or decouple from the first connector 102 and effectively close the fluid path between the first connector 102 and the second connector 140, as described herein.

[0075] The second connector 140 can decouple from the first connector 102 in response to the pull-out force exceeding the predetermined threshold force. When the pull-out force exceeds the predetermined threshold force, the flange 148 flexes or bends radially outward as the ridge 160 is axially pulled out of and displaced from the groove 109. For example, in response to the pull-out force exceeding the predetermined threshold force, the second connector 140 can move axially relative to the first connector 102 such that the flange 148 flexes or deflects radially outward, causing the ridge 160 to be displaced from the groove 109, and the second connector 140 is no longer secured to the first connector 102.

[0076] In some embodiments, after decoupling the first connector 102 from the second connector 140, a user sterilizes the first connector 102 and recouples the first connector 102 to the second connector 140. In some embodiments, the user can sterilize the first connector 102 and / or the second connector 140. The first connector 102 can be recoupled to the second connector 140 by inserting the first connector 102 into the second connector 140 (e.g., the gap 153). The first connector 102 can move axially relative to the second connector 140 to couple the first connector 102 to the second connector 140 by engaging the groove 109 with the ridge 160 of the flange 148 to secure the second connector 140 to the first connector 102. Recoupling the first connector 102 to the second connector 140 causes the coupler assembly 100 to transition from the second configuration to the first configuration.

[0077] Figure 5A FIG. 4 is a diagram illustrating a computer simulation of a deformation of the second connector of FIG. 4, in accordance with various aspects of the present disclosure. Figure 5B FIG. 4 is a diagram illustrating a computer simulation of a deformation of the second connector of FIG. 4, in accordance with various aspects of the present disclosure.

[0078] In some embodiments, the flange 148 is configured to flex and bend, causing the flange 148 to strain. For example, the flange 148 can flex radially outward away from its radially inward biased position. As the flange 148 flexes radially outward, the ridge 160 of the flange 148 can be displaced from the groove 109 of the first connector 102.Figure 5A As shown, the flange 148 can flex radially outward compared to the biased position of the flange 148 shown in the black box. The flange 148 can be biased radially inward in its normal, unflexed position compared to when the flange 148 is flexed radially outward. The flange 148 can flex radially outward to couple the second connector 140 to the first connector 102. After coupling the second connector 140 to the first connector 102, the flange 148 can return to its normally biased radially inward position (e.g., shown in the black box of FIG. 1). As shown, the flange 148 is configured to flex and deform, causing the flange 148 to strain. The flange 148, as well as the ring 146, can be composed of a material that allows for flexing without deforming. Figure 5A As shown, the flange 148 is configured to flex and deform, causing the flange 148 to strain. The flange 148, as well as the ring 146, can be composed of a material that allows for flexing without deforming. Figure 5B As shown, the flange 148 is configured to flex and deform, causing the flange 148 to strain. The flange 148, as well as the ring 146, can be composed of a material that allows for flexing without deforming.

[0079] Figure 6A is a cross-sectional view of a coupling assembly having a second connector with a center rib in accordance with various aspects of the present disclosure. Figure 1 is a cross-sectional view of a coupling assembly having a second connector with a center rib in accordance with various aspects of the present disclosure. Figure 6B is a cross-sectional view of a coupling assembly having a second connector with a center rib in accordance with various aspects of the present disclosure. Figure 6A is a cross-sectional view of a coupling assembly having a second connector with a center rib in accordance with various aspects of the present disclosure.

[0080] Referring to Figures 6A-6B The coupling assembly 100 can include a second connector 140'. The second connector 140' can be substantially similar to the second connector 140, but the second connector 140' can include a rib 170. The rib 170 can be configured to center the second connector 140 along the central axis A-A and prevent slippage between the ridge 160 and the groove 109. The rib 170 can be disposed on the outer periphery of the housing 144. In some embodiments, the rib 170 is disposed circumferentially around the housing 144 such that the rib 170 is disposed within the gap 153. The rib 170 can be configured to reduce the contact surface area between the housing 144 of the second connector 140 and the mating portion 105. In some embodiments, the rib 170 reduces the frictional force between the mating portion 105 and the housing 144, thereby allowing the second connector 140 to easily separate from the first connector 102 in response to a breakaway event.

[0081] When the second connector 140 is coupled to the first connector 102, the rib 170 can engage with the mating portion 105 of the first connector 102. The rib 170 can be configured to reduce the frictional force between the mating portion 105 and the housing 144 to allow the first connector 102 to decouple from the second connector 140 when the pullout force exceeds a predetermined amount. In some embodiments, the rib 170 is configured to secure the second connector 140 in place (e.g., centered) relative to the first connector 102 to prevent disruption in fluid flow from the first connector 102 to the second connector 140. In some embodiments, the second connector 140’ with the rib 170 reduces the pullout force required to decouple the second connector 140 from the first connector 102.

[0083] Referring to Figures 7A-7B The coupler assembly 100 can include a second connector 140”. The second connector 140” can be substantially similar to the second connector 140’ and the second connector 140, but the second connector 140” can include a ring 180. The ring 180 can be configured to form a support surface between the groove 109 and the ridge 160” / flange 148”. For example, similar to the second connector 140 and 140’, the second connector 140” can include a flange 148” having a ridge 160” configured to engage with the groove 109 of the mating portion 105. The ring 180 can be configured to help secure the first connector 102 to the second connector 140” when the second connector 140” is coupled to the first connector 102. For example, the ring 180 can be configured to stabilize the first connector 102 and the second connector 140” together when the second connector 140” is coupled to the first connector 102. In some embodiments, the ring 180 is configured to abut the mating portion 105 when the ridge 160” is disposed within or proximate to the groove 109. For example, the ring 180 can be disposed circumferentially around the mating portion 105 when the second connector 140” is coupled to the first connector 102. In some embodiments, the flange 148” does not include the ridge 160”, but rather includes the ring 180 to help secure the mating portion 105 to the second connector 140.
