Description

Technical Field

[0001] This disclosure relates generally to connectors, and particularly to a non-disconnectable rotatable connector. Background Technology

[0002] Medical treatments typically involve infusing a patient with medical fluids (e.g., saline solutions or liquid medications) using an intravenous (IV) catheter. This IV catheter is connected to a fluid source (e.g., an IV bag) via an arrangement of flexible tubing and fittings, often referred to as an “IV kit.” Typically, the fittings or catheters are interlocked or secured to each other to allow fluid communication between the various parts of the fitting or catheter.

[0003] In some applications, such fittings or conduits may break due to improper fastening and / or when the connection is subjected to forces greater than it was designed to withstand. A broken fitting or conduit can be dangerous when used with hazardous pharmaceuticals. For example, breaking a fitting used for the delivery of hazardous pharmaceutical injections or infusions could cause injury to individuals in the vicinity. Utility Model Content

[0033] The disclosed connector includes a cover and a Luer element configured to engage with a coupling device. The connector can have a first configuration and a second configuration. In the first configuration, the connector is not engaged with the coupling device. In the second configuration, the connector is engaged with the coupling device.

[0034] A connector can be configured to attach a first portion of a tubing to a second portion of the tubing. For example, the first portion of the tubing can be attached to a connector, and the second portion of the tubing can be attached to a coupling device. The first portion and / or the second portion of the tubing can also be attached to a patient or fluid source. In some embodiments, the connector allows fluid to flow from the first portion of the tubing to the second portion of the tubing. For example, when the connector is attached to a coupling device, a fluid path can be formed through the connector and the coupling device to allow fluid to flow from the first portion of the tubing through the connector and the coupling device to the second portion of the tubing. The fluid path can allow fluid to flow from the second portion of the tubing through the coupling device and the connector to the first portion of the tubing. In some embodiments, the second portion of the tubing is attached to a syringe. The second portion of the tubing can be a syringe containing a drug or medication.

[0035] In some embodiments, the coupling device is configured to remain engaged with the connector even when a force is applied. For example, when the coupling device is engaged with the connector, a pull-out force can be applied to a portion of the syringe or tubing engaged with the coupling device. The connector can remain engaged with the coupling device in response to the pull-out force to prevent the connector from disengaging from the coupling device. The pull-out force can be a force generated along the longitudinal axis of the coupling device and / or the connector. In some embodiments, the pull-out force is caused by dragging or pulling a second portion of the syringe or tubing engaged with the coupling device. Alternatively, the pull-out force applied to the coupling device can be caused by dragging or pulling a first portion of the connector and / or tubing engaged with the connector.

[0036] In some embodiments, the second portion of the fitting and / or the syringe may contain hazardous substances, such as hazardous pharmaceuticals. A connector configured to prevent separation prevents leakage or spillage of hazardous pharmaceuticals. If exposed and / or not contained in a suitable container, vessel, or delivery device, hazardous materials may be harmful to those nearby. A connector that remains engaged with the coupling device in response to pull-out force prevents exposure of hazardous pharmaceuticals to those nearby.

[0037] The specific embodiments described below are intended as descriptions of various configurations of the subject matter and are not intended to represent the only configuration in which the subject matter can be practiced. Specific details are included to provide a thorough understanding of the subject matter. However, it will be apparent to those skilled in the art that the subject matter can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject matter. For ease of understanding, the same components are labeled with the same reference numerals. Reference numerals may have additional letter suffixes to indicate individual instances of common elements, while generally they are referred to by the same number without a suffix.

[0038] While the following description pertains to medical fittings used for administering medical fluids with the disclosed connectors, it should be understood that this description is merely an example of use and does not limit the scope of the claims. Various aspects of the disclosed connectors can be used in any application where it is desirable to secure connections to a wide variety of tubing and fittings.

[0039] The disclosed connector overcomes several challenges found with certain conventional connectors. One challenge with certain conventional connectors is that they can be easily dislodged. For example, some conventional connectors may release in response to pull-out forces experienced by a patient turning over in bed, a patient grabbing a fitting or line on a bed rail, moving a patient to a different bed, a restless pediatric patient, and / or a disoriented adult patient pulling out their line. In fact, the 2017 Association for Vascular Access (AVA) Annual Scientific Meeting reported a displacement rate of 10% per 1,000 patients with peripheral IV catheters, equivalent to approximately 33 million displacements annually in the United States alone. Because accidental or unintentional displacement of fittings, catheters, or accessories can interrupt the administration of medical fluids, the use of certain conventional connectors is not desirable.

[0040] Therefore, according to this disclosure, it is advantageous to provide a connector and connector / connector assembly as described herein that prevents disconnection in response to pull-out force. The disclosed connector and connector / connector assembly are constructed as described herein to allow the connector to be securely held to the coupling device in response to pull-out force.

[0042] refer to Figure 1A-1B The connector 100 allows fluid (such as medical fluid) to flow from a fluid source (e.g., a syringe or tubing) to the patient end by fluidly connecting a portion of a syringe or tubing to another portion of a tubing or tubing. The connector 100 can be configured to connect to a coupling device (e.g., coupling device 200) that can connect to a fluid source containing, for example, a hazardous medicine.

[0043] In some embodiments, connector 100 includes a central axis AA, and connector 100 and a coupling device are connected in series along the central axis AA. The central axis AA may extend longitudinally along the length of connector 100. Connector 100 may have a first configuration and a second configuration. In the first configuration, connector 100 is separate from the coupling device. In the second configuration, connector 100 is coupled to the coupling device. Connector 100 may be coupled to the coupling device such that the central axis AA extends through connector 100 and the coupling device.

[0044] In some embodiments, connector 100 is coupled to a first portion of a tubing to allow the first portion of the tubing to be connected to a coupling device. Connector 100 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 the tubing), one or more connectors, and / or coupled to a syringe, and the second end 103 may be configured to receive a coupling device. In some embodiments, a portion of the tubing may be coupled to or engaged with the first end 101 of connector 100. Connector 100 may be in fluid communication with the tubing via the first end 101 to allow fluid to pass through connector 100. In some embodiments, the first end 101 may have a flat surface to allow clinicians to easily clean and sterilize 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 positioned along the longitudinal length of connector 100. For example, the first end 101 and the second end 103 may be positioned along a central axis AA. The first end 101 and / or the second end 103 may include openings to allow fluid communication between the first end 101 and / or the second end 103 and one or more components (e.g., pipes, connectors, valves, collars, accessories, syringes, etc.). For example, the first end 101 may be coupled to a pipe, and the second end 103 may include openings to allow fluid communication through the connector 100.

[0045] In some embodiments, fluid may exit or flow through connector 100 via a second end 103 disposed opposite to the first end 101. The flow path through connector 100 may have a straight fluid path to facilitate flushing and reduce the risk of hemolysis. Optionally, connector 100 may include features (e.g., protrusions, gripping features) disposed on the outer surface of connector 100 to allow clinicians to more easily grasp or manipulate the first connector 100. Some embodiments of connector 100 may provide connectors compatible with connectors for other parts of the fluid delivery system. Connector 100 may be substantially cylindrical in shape.

[0046] In some embodiments, connector 100 includes a housing 102. Housing 102 may be substantially cylindrical in shape and may include a fitting portion 107 and a mating portion 105. The fitting portion 107 may be located adjacent to a first end 101, and the mating portion 105 may be located adjacent to a second end 103. The fitting portion 107 may accommodate an end connector 160, which may be configured to engage with a portion of the fitting, allowing connector 100 to be in fluid communication with that portion of the fitting.

[0047] In some embodiments, the mating portion 105 is disposed opposite to the fitting portion 107, and the connecting device is configured to be at least partially disposed within the mating portion 105 to secure the connector 100 to the connecting device. For example, the mating portion 105 may include a Luer element 120 configured to engage with the connecting device (e.g., connecting device 200) to secure the connecting device to the connector 100, as described below. The Luer element 120 may be at least partially disposed within the mating portion 105 near the second end 103. In some embodiments, the Luer element 120 is configured to engage and engage with a portion of the connecting device to secure the connecting device to the connector 100. The Luer element 120 may be disposed within the housing 102 such that a portion of the housing 102 (e.g., the mating portion 105) is disposed circumferentially around the Luer element 120. A groove 109 may be continuously disposed circumferentially around the mating portion 105.

[0048] The housing 102 may be substantially cylindrical and may be configured to receive the Luer element 120. In some embodiments, when the Luer element 120 is engaged with a coupling device, the coupling device is at least partially disposed within the housing 102. The housing 102 may include a groove 109 disposed circumferentially around the housing 102 (e.g., around the mating portion 105). The groove 109 may be configured to assist a user in rotating the housing 102. In some embodiments, the tubular portion 107 has a larger diameter than the maximum diameter of the mating portion 105. For example, the housing 102 may taper gradually from a first end 101 to a second end 103. In some embodiments, the tubular portion 107 and the mating portion 105 form an integral structure including the housing 102.

[0049] In some embodiments, housing 102 is configured to receive and accommodate end connector 160. End connector 160 may be at least partially disposed within fitting portion 107. End connector 160 may be positioned closer to first end 101 than second end 103. Housing 102 may include a housing ring or ring 110 located at first end 101. Ring 110 may extend radially inward from housing 102. In some embodiments, ring 110 is one or more protrusions arranged circumferentially and extending radially inward along the inner surface of housing 102. In some embodiments, ring 110 extends radially inward toward a central axis AA. Housing 102 may be hollow, such that housing 102 may receive and accommodate one or more components. For example, housing 102 may include an internal space 111, and ring 110 may extend radially inward into the internal space 111. In some embodiments, ring 110 extends perpendicularly toward central axis AA.

[0050] In some embodiments, a second portion of the tubing is terminated by a coupling device (e.g., coupling device 200) to allow the second portion of the tubing to connect and / or disconnect from the connector 100. In some embodiments, the housing 102 includes features and / or components (e.g., Luer element 120) that allow the connector 100 to be coupled to the coupling device. The coupling device (e.g., coupling device 200) may be coupled to a syringe or fluid source via the tubing. In some embodiments, the syringe or fluid source coupled to the coupling device includes a hazardous drug. Exposure to a hazardous drug may be harmful to an individual. The connector 100 may be configured to remain connected to the coupling device in response to a pull-out force to prevent disengagement and exposure of the hazardous drug.

[0051] As can be understood, connector 100 and coupling device (e.g., coupling device 200) can be coupled and disengaged to allow fluid communication as desired. Connector 100 can be coupled to coupling device 200 to provide a needle-free connection. Advantageously, connector 100 can be mated with coupling device 200 to form a leak-free closed system, allowing the delivery of various pharmaceuticals or fluids.

Luer assembly 180 may be configured to be at least partially disposed within sleeve 140 such that sleeve 140 circumferentially surrounds Luer assembly 180. In some embodiments, Luer assembly 180 includes channels to allow fluid paths through Luer assembly 180. For example, Luer element 120 and end connector 160 may each include fluid-communicating channels to allow fluid paths through Luer assembly 180.

[0054] In some embodiments, the Luer element 120, sleeve 140, and end connector 160 are disposed within the housing 102. For example, the Luer element 120, sleeve 140, and end connector 160 may be disposed within an internal space 111 of the housing 102.

[0063] In some embodiments, Luer element 120 includes a channel 127, and end connector 160 includes a channel 167. Channels 127 and 167 may be disposed along a central axis AA and may be in fluid communication with each other. Channel 127 may extend through Luer element 120 to allow fluid flow through Luer element 120. In some embodiments, channels 127 and 167 form a fluid path through Luer assembly 180 and connector 100. When a coupling device (e.g., coupling device 200) is coupled to connector 100, a portion of the coupling device may be disposed within channel 127 to form an airtight or watertight path between the coupling device and connector 100. Channel 167 may be configured to be in fluid communication with a fitting (e.g., an IV fitting). For example, end connector 160 may be configured to be coupled to or integrated with a fluid connection system (e.g., a fitting) to allow fluid to be delivered through connector 100 to a patient.

[0064] refer to Figures 6A-7C Luer element 120 may be disposed within sleeve 140, which may be coupled to end connector 160 and disposed within housing 102. In some embodiments, Luer element 120 is inserted through sleeve 140, and end connector 160 is coupled to Luer element 120 at a first end 121. Once coupled together, Luer element 120, sleeve 140, and end connector 160 may be inserted into housing 102 such that a ring 110 of housing 102 is disposed within a groove 164 of end connector.

[0065] In some embodiments, the housing 102 includes one or more slots 113 near the location where the fitting portion 107 and the mating portion 105 meet or connect. The slots 113 may be located on the inner or internal surface of the housing 102 and may be located at a point where the diameter of the housing 102 decreases. In some embodiments, when the Luer element 120 is disposed in the sleeve 140 and coupled to the end connector 160 and disposed within the housing 102, the sleeve base 142 is positioned near the slots 113 such that a protrusion 148 engages with and is disposed within the slots 113 to prevent further axial movement of the sleeve 140 toward the second end 123. The coupling of the Luer element 120 to the end connector 160 may form a Luer assembly 180, which may be disposed within the sleeve 140.

[0066] In some embodiments, the Luer assembly 180 and the sleeve 140 are disposed and secured within the housing 102 because the ring 110 is disposed within the groove 164. For example, the Luer assembly 180 may be disposed within the sleeve 140, and the ring 110 of the housing 102 may be configured to deflect or bend and may bend during insertion of the Luer assembly 180 into the housing 102. The ring 110 may deflect or bend as the Luer assembly 180 moves axially toward the first end 103. Because the Luer assembly 180 is disposed within the sleeve 140, the Luer assembly 180 and the sleeve 140 may move axially toward the second end 103 until the protrusion 148 of the sleeve base 142 contacts or engages with the slot 113. The protrusion 148 may be disposed within the slot 113 to prevent further axial movement of the sleeve 140 toward the first end 101.

[0067] The engagement of the protrusion 148 with the slot 113 and / or its placement within the slot can occur simultaneously with the placement of the ring 110 within the groove 164. The protrusion 148, placed within the corresponding slot 113, prevents axial movement of the sleeve 140 toward the second end 103 of the housing 102, and the ring 110, placed within the groove 164, prevents axial movement of the end connector 160 and the Luer element 120 relative to the housing 102. In some embodiments, the ring 110 placed within the groove 164 allows rotation of the housing 102 relative to the end connector 160. The housing 102 may include a plurality of slots 113 corresponding to the number of protrusions 148 on the sleeve 140.

[0068] In some embodiments, the sleeve 140 is axially movable relative to the Luer component 120, the end connector 160, and the housing 102. For example, when the Luer component 180 and the sleeve 140 are disposed and secured within the housing 102, the Luer component 180 may be fixed relative to the housing 102 (e.g., immovable), and the sleeve 140 may be axially movable relative to the housing 102 and the Luer component 180.

[0069] In some embodiments, Luer element 120 is coupled to end connector 160 to form Luer assembly 180. For example, Luer element 120 may include a recessed groove 129 configured to receive a top portion 169 of end connector 160. Luer element 120 may be fixedly coupled to the top portion 169 of end connector 160 such that Luer element 120 and end connector 160 form an integral structure. In some embodiments, Luer element 120 (e.g., groove 129) is solvent-bonded to the top portion 169 such that Luer element 120 is fixedly coupled to end connector 160. Alternatively, Luer element 120 may be fixedly coupled to end connector 160 using magnets, fasteners, adhesives, screws, or any other coupling mechanism.

[0070] In some embodiments, the sleeve 140 includes a protrusion 154 extending radially inward from the inner surface of the sleeve 140. In some embodiments, the protrusion 154 is a rib-like protrusion. The protrusion 154 may be a ring disposed circumferentially along the inner surface of the sleeve 140 and may be configured to extend radially inward. The Luer element 120 may include one or more slots 132, and the protrusion 154 may be configured to engage with the slots 132. For example, the sleeve 140 may slide on the Luer element 120 from a second end 123 to a first end 121. In some embodiments, the slot 132 is formed due to the alignment of a recessed portion of the Luer element 120 with a recessed edge 171 of the end connector 160. In other words, a portion of the Luer element 120 and a portion of the end connector 160 may form the slot 132. In some embodiments, the sleeve 140 is inserted into the housing 102 such that the protrusion 148 is disposed in or near the slot 113 to prevent the sleeve 140 from moving axially relative to the housing 102 toward the second end 103 of the housing 102.

[0071] In some embodiments, the Luer assembly 180 is configured to be coupled to a coupling device (e.g., coupling device 200). For example, the coupling device may be configured to engage with a Luer element 120 (e.g., coupling portion 124) to secure the coupling device to the Luer assembly 180. The coupling device may be coupled to the Luer assembly 180 such that the coupling device cannot be removed from the Luer assembly 180 due to pull-out forces. In some embodiments, when the coupling device is coupled to the Luer assembly 180, the coupling device is at least partially disposed within the housing 102 because the coupling portion 124 is disposed within the housing 102.

[0072] In some embodiments, Luer element 120 is coupled to end connector 160 such that Luer element 120 is axially fixed in place relative to end connector 160. As described above, top portion 169 may be disposed within recessed groove 129 such that end connector 160 is coupled to Luer element 120. Luer element 120 may be coupled to end connector 160, which may be coupled to housing 102. For example, ring 110 of housing 102 may be disposed within groove 164 to secure end connector 160 to housing 102. Ring 110 of housing 102 disposed within groove 164 results in end connector 160 being fixed relative to housing 102. In some embodiments, Luer element 120 is coupled to end connector 160, and end connector 160 is coupled to housing 102, resulting in Luer element 120 being axially fixed relative to end connector 160 and housing 102.

[0073] The Luer assembly 180 may be at least partially disposed within the sleeve 140. The sleeve 140 may be axially movable relative to the Luer assembly 180. The sleeve 140 may also be movable relative to the housing 102. The sleeve 140 may be configured to move relative to the Luer assembly 180 and the housing 102 toward a first end 101 and a second end 103 of the housing 102. In some embodiments, engagement of the coupling device with the Luer assembly 180 results in axial movement of the sleeve 140 relative to the housing 102 and the Luer assembly 180.

[0074] In some embodiments, the connecting portion 124 includes threads, such as female threads, configured to engage with the threads (e.g., male threads) of a connecting device to secure the connecting device to the Luer member 120 of the Luer assembly 180. In some embodiments, engagement of the connecting device with the Luer member 120 results in axial movement of the sleeve 140 toward a first end 101 of the housing 102. For example, the connecting device may thread-engage with the connecting portion 124 and rotate downward along the Luer member 120 toward the first end 101, such that the connecting device is axially rotated / screwed onto the connecting portion 124 of the Luer member 120.

[0075] refer to Figures 7A-7CAs the connecting device (e.g., connecting device 200) rotates axially downward along the Luer member 120 via the connecting portion 124, the connecting device can contact the sleeve 140. Further rotation of the connecting device causes the connecting device to move axially toward the first end 101 and pushes the sleeve 140 toward the first end 101. The sleeve 140 can slide downward relative to the Luer assembly 180 or move axially toward the first end 101 such that the locking ring 170 of the end connector 160 engages with and is disposed in the groove 152 of the sleeve 140. The groove 152 of the sleeve 140 can be a recessed groove provided on the inner surface of the sleeve base 142. For example, the groove 152 can be provided circumferentially along the inner surface of the sleeve base 142.

[0076] In some embodiments, the locking ring 170 is configured to bend or flex such that the locking ring 170 flexes when the sleeve 140 is pushed against it. For example, the sleeve 140 may apply a force or pressure to the locking ring 170 as the sleeve 140 moves axially toward the first end 101 of the housing 102. The locking ring 170 may bend or deflect to allow the locking ring 170 to be positioned within the groove 152. The locking ring 170 may be configured to bend or deflect until the pressure or force from the sleeve 140 is removed to allow the locking ring 170 to be positioned within the groove 152. When the locking ring 170 is positioned within the groove 152 of the sleeve 140, the sleeve 140 may be axially fixed relative to the Luer assembly 180. In other words, the locking ring 170 being positioned within the groove 152 results in the sleeve 140 being secured to the end connector 160, which is secured to the Luer assembly 120 and the housing 102.

[0077] In some embodiments, the locking ring 170 is shaped to allow the sleeve 140 to move toward the first end 101 through the locking ring 170, but not in the opposite direction. The groove 152 may include an edge 149. The locking ring 170 may be beveled circumferentially, and the edge 149 of the sleeve 140 may be beveled circumferentially to allow the locking ring 170 to move past the edge 149 as the sleeve 140 moves toward the first end 101. The locking ring 170 and the edge 149 may be beveled to allow the sleeve 140 to move toward the first end 101, thereby allowing the locking ring 170 to be positioned within the groove 152, but preventing the sleeve 140 from moving toward the second end 103, thereby preventing the locking ring 170 from being removed from the groove 152. In other words, the locking ring 170 and the groove 152 may be sized and shaped to allow the sleeve 140 to move axially toward the first end 101 so that the locking ring 170 is positioned within the groove 152.

[0078] When the locking ring 170 is positioned within the groove 152, the sleeve 140 can be axially fixed relative to the end connector 160 and the Luer element 120. For example, once the locking ring 170 is positioned within the groove 152, axial movement of the sleeve 140 toward the first end 101 or the second end 103 is prevented. Because the coupling device (e.g., coupling device 200) axially pushes the sleeve 140 toward the first end 101, the sleeve 140 can move axially toward the first end 101 to position the locking ring 170 within the groove 152. This results in the locking ring 170 being positioned within the groove 152. In some embodiments, the coupling device is fully engaged with the Luer element 120, resulting in the locking ring 170 being positioned within the groove 152.

[0079] refer to Figures 7B-7C The sleeve 140 moves axially downward toward the first end 101, causing the locking ring 170 to be positioned within the groove 152, the protrusion 148 to move axially downward toward the first end 101 within the slot 132, and the protrusion 154 to move axially downward toward the first end 101 within the slot 113. The axial downward movement of the protrusion 148 within the slot 132 and the protrusion 154 within the slot 113 causes the sleeve 140 and the Luer assembly 180 to be rotatable relative to the housing 102. The housing 102 may include a notch 115. The notch 115 may be positioned toward the first end 101 adjacent to the slot 113, relative to the second end 103. The notch 115 may extend partially along the slot 113 and may allow the protrusion 148 to enter and exit the slot 113. In some embodiments, the protrusion 148 moves axially downward toward the first end 101 within the slot 113 such that the protrusion 148 is positioned adjacent to the notch 115, allowing the protrusion 148 to rotate out of the slot 113, and thus allowing the housing 102 to be rotatable relative to the sleeve 140.

Figure 11 Based on all aspects of this disclosure Figure 1AA front perspective view of the connector that is attached to the coupling device.

[0081] refer to Figures 8-11 The coupling device 200 can be configured to engage with the connector 100. The coupling device 200 can be a syringe, Luer element, or tubing connected to a fluid source. The engagement of the coupling device 200 with the connector 100 results in a fluid path being formed between the connector 100 and the coupling device 200, allowing fluid to flow from the fluid source through the coupling device 200 and the connector 100 to the patient. In some embodiments, the coupling device 200 is a male Luer element configured to engage with Luer element 120. Luer element 120 can be a female Luer element with threads configured to engage with the coupling device 200.

[0082] The coupling device 200 may include a first end 201 and a second end 203 opposite to the first end 201. The coupling device 200 may include a base 202 disposed at the first end 201 and a body 204 disposed near the second end 203. In some embodiments, the coupling device 200 includes a tube 206. The tube 206 may extend from the base 202 and may extend through the body 204. In some embodiments, the tube 206 is in fluid communication with the base 202. The body 204 may be coupled to the base 202 and circumferentially surrounds the tube 206. The body 204 may include an inner surface having a coupling mechanism. For example, the inner surface of the body 204 may include threads configured to engage with the threads of the coupling portion 124 of the Luer member 120.

[0083] In some embodiments, when the coupling device 200 is coupled to the connector 100, the tube 206 is at least partially disposed within the channel 127 of the Luer element 120. For example, coupling the coupling device 200 to the Luer element 120 causes the tube 206 to be at least partially disposed within the channel 127 to allow fluid to flow from a fluid source through the tube 206, into the channel 127 and the channel 167, and out of the connector 100.

[0084] refer to Figures 9A-9B The connecting device 200 is rotatable to engage threadedly with the Luer element 120 (e.g., the connecting portion 124). For example, threads on the inner surface of the body 204 can engage with threads on the outer surface of the connecting portion 124, resulting in the connecting device 200 being connected to the Luer element 120, and the tube 206 being at least partially disposed within the channel 127. In some embodiments, the connector 100 is configured in a first configuration ( Figures 9A-9B ) and second configuration ( Figures 10A-10BIn the first configuration, the coupling device 200 is disengaged from or partially coupled to the connector 100 via the Luer element 120. The coupling device 200 rotates relative to the Luer element 120 to secure the coupling device 200 to the connector 100. In the first configuration, the coupling device 200 is partially engaged with the Luer element 120 and does not contact or abut against the sleeve 140. In the second configuration, the coupling device 200 is fully engaged with the Luer element 120 and pushes the sleeve 140 downward toward the first end 101.

[0085] refer to Figures 9A-9B In the first configuration, the locking ring 170 is not disposed within the groove 152, but is positioned closer to the first end 101 than the groove 152. Compared to when the connector 100 is in the second configuration, the protrusion 154 may be disposed in the slot 132 near the Luer element 120, and the protrusion 148 may be disposed in the slot 113 near the second end 103. In the first configuration, the protrusion 148 may not be disposed within the recess 115, thereby preventing the housing 102 from rotating relative to the sleeve 140. In the first configuration, the sleeve 140 is axially movable relative to the end connector 160.

[0086] refer to Figures 10A-10B In the second configuration, the locking ring 170 is disposed within the groove 152. Compared to when the connector 100 is in the first configuration, the protrusion 154 may be disposed in the slot 132 near the end connector 160, and the protrusion 148 may be disposed in the slot 113 near the first end 101. In the second configuration, the protrusion 148 may be disposed within the recess 115, thereby allowing the housing 102 to rotate relative to the sleeve 140. In the second configuration, axial movement of the sleeve 140 relative to the end connector 160 is prevented.

[0087] In comparison Figure 9B (First Configuration) and Figure 10B (Second configuration) In Figure 9B In the first case, the connecting device 200 does not contact or push the sleeve 140, resulting in the locking ring 170 not being positioned within the groove 152. When the connecting device 200 rotates and screws downwards relative to the Luer assembly 120 toward the first end 101, the connecting device 200 pushes the sleeve 140 downwards, causing the sleeve 140 to move axially relative to the Luer assembly 180 and the housing 102. This causes the locking ring 170 to be positioned within the groove 152, and the protrusion 148 to move downwards in the slot 113, allowing the protrusion 148 to engage with the recess 115.

[0088] refer to Figure 11When the connecting device 200 is fully engaged and secured to the connector 100 (e.g., Luer element 120), causing the protrusion 148 to engage with the recess 115, the housing 102 is rotatable relative to the sleeve 140 and the Luer assembly 180. This rotatability of the housing 102 relative to the sleeve 140 and the Luer assembly 180 prevents the user from rotating the Luer assembly 180 and the sleeve 140, and thus prevents removal of the connecting device 200. For example, to disengage the connecting device 200 from the Luer element 120 and therefore from the connector 100, the connecting device 200 must be rotated relative to the Luer element 120. However, in the second configuration, the connecting device 200 is not rotatable relative to the Luer element 120 because rotation of the connecting device 200 would cause rotation of the Luer element 120. This allows the connecting device 200 to remain connected to the Luer element 120 and to be rotatable relative to the housing 102.

[0089] When the coupling device 200 is fully engaged with the connector 100 via the Luer element 120 (e.g., in the second configuration), the housing 102 becomes rotatable relative to the sleeve 140 and the Luer assembly 180. This prevents the user from rotating the coupling device 200 relative to the Luer element 120, and therefore prevents the user from disengaging the coupling device 200 from the connector 100. For example, since the Luer element 120 (and the sleeve 140 and the end connector 160) is disposed within the housing 102, and the housing 102 is rotatable relative to the Luer element 120 (and the sleeve 140 and the end connector 160), the user cannot rotate the coupling device 200 relative to the Luer element 120 because, when the connector 100 is in the second configuration, rotation of the coupling device 200 would cause rotation of the Luer element 120. In the second configuration, the user cannot rotate the coupling device 200 relative to the Luer element 120 because rotation of the coupling device 200 would cause rotation of the Luer element 120, which rotates within the housing 102. The user cannot access the Luer element 120 because it is housed within the housing 102, and therefore the user cannot prevent the Luer element 120 from rotating when the connecting device 200 rotates.

[0090] In practice, if a user grasps the housing 102 and attempts to rotate the coupling device 200 relative to the connector 100, the coupling device 200, Luer assembly 180, and sleeve 140 will rotate relative to the housing 102, preventing the user from separating the coupling device 200 from the connector 100. The second configuration of the connector 100 and coupling device 200 prevents the user from separating the coupling device 200 from the connector 100. Furthermore, the second configuration prevents the coupling device 200 from unintentionally separating from the connector 100 in response to an axial force (e.g., a pull-out force) applied to the connector 100 and / or the coupling device 200.
