Description

Technical Field

[0001] The present disclosure generally relates to connectors, and particularly to a non-disconnectable rotatable connector. Background Art

[0002] Medical treatment typically involves the infusion of a medical fluid (e.g., saline solution or liquid drug) to a patient using an intravenous (IV) catheter, which is connected to a fluid source (e.g., an IV bag) through an arrangement of flexible tubing and fittings commonly referred to as an "IV set". Generally, the tubing or catheters are coupled or secured to each other to allow fluid communication between the various parts of the tubing or catheters.

[0003] In some applications, such tubing or catheters may disconnect due to improper securing and / or when the coupling is subjected to a force greater than the force the coupling is designed to withstand. When using hazardous drugs, a disconnected tubing or catheter can be dangerous. For example, disconnecting the tubing used for the injection or infusion of a hazardous drug can cause harm to surrounding individuals. Summary of the Invention

[0033] The disclosed connector includes a cap and a luer configured to couple to a coupling device. The connector can have a first configuration and a second configuration. In the first configuration, the connector is not coupled to the coupling device. In the second configuration, the connector is coupled to the coupling device.

[0034] The connector can be configured to couple a first portion of a tubing to a second portion of the tubing. For example, the first portion of the tubing can be coupled to the connector and the second portion of the tubing can be coupled to the coupling device. 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 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 coupled to the 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 coupled 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 coupled to the connector even when a force is applied. For example, when the coupling device is coupled to the connector, a pull-out force can be applied to a syringe or a portion of the tubing coupled to the coupling device. The connector can remain coupled to the coupling device in response to the pull-out force to prevent the connector from separating 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 the second portion of the syringe or tubing coupled to the coupling device. Alternatively, the pull-out force applied to the coupling device can be caused by dragging or pulling the first portion of the connector and / or the tubing coupled to 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 can prevent the leakage or spillage of hazardous pharmaceuticals. Hazardous substances can be harmful to surrounding individuals if exposed and / or not contained within a suitable container, vessel, or delivery device. The connector that remains coupled to the coupling device in response to a pulling force prevents hazardous pharmaceuticals from being exposed to surrounding individuals.

[0037] The following detailed description is intended as a description of various configurations of the present subject matter and is not intended to represent the only configurations in which the present subject matter may be practiced. For purposes of providing a thorough understanding of the present subject matter, the detailed description includes specific details. It will be apparent, however, to one of ordinary skill in the art that the present subject matter may 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 present subject matter. For ease of understanding, like components are labeled with like reference numerals. The reference numerals may have additional letter suffixes to indicate separate instances of common elements, while generally being referred to by the same number without the suffix letter.

[0038] Although the following description is directed to using the disclosed connector to connect medical fittings for administering medical fluids, 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 connector can be used in any application where a connection of various fittings and tubes is desired.

[0039] The disclosed connector overcomes several challenges found with certain conventional connectors. One challenge with certain conventional connectors is that some conventional connectors may be prone to separation. For example, some conventional connectors may release in response to the pulling forces experienced when a patient turns over in bed, a patient grabs a fitting or tube on a bedrail, the patient is moved to a different bed, a pediatric patient fidgets, and / or a disoriented adult patient pulls out their tube. In fact, the 2017 Annual Scientific Meeting of the Association for Vascular Access (AVA) reported that the displacement rate for 1,000 patients with peripheral IV catheters was 10%, which equates to approximately 33 million displacements per year in the United States alone. Because accidental or unintentional displacement of a fitting, catheter, or accessory can interrupt the administration of medical fluids, the use of some conventional connectors is not desirable.

[0040] Accordingly, it is advantageous, in accordance with the present disclosure, to provide a connector and a connector / connector assembly as described herein that prevent disconnection in response to a pulling force. The disclosed connector and connector / connector assembly are constructed as described herein to permit the connector to remain securely coupled to the coupling device in response to a pulling force.

[0041] Figure 1AIs a front perspective view of a connector according to various aspects of the present disclosure. Figure 1B Is Figure 1A A bottom perspective view of the connector of.

[0042] Reference Figure 1A - 1B , the connector 100 allows fluid (such as a medical fluid) to flow from a fluid source (such as a syringe or a fitting) to the patient end by fluidly coupling a portion of a syringe or a fitting to another portion of a pipeline or a fitting. The connector 100 can be configured to be coupled to a coupling device (such as the coupling device 200), which can be coupled to a fluid source containing, for example, a hazardous drug.

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

[0044] In some embodiments, the connector 100 is coupled to a first portion of a fitting to allow the first portion of the fitting to be connected to a coupling device. The connector 100 can include a first end 101 and a second end 103. The first end 101 can be coupled to a fitting (such as a first portion of a fitting), one or more connectors, and / or combined with a syringe, and the second end 103 can be configured to receive a coupling device. In some embodiments, a portion of the fitting can be coupled to or engaged with the first end 101 of the connector 100. The connector 100 can be in fluid communication with the fitting via the first end 101 to allow fluid to pass through the connector 100. In some embodiments, the first end 101 can have a flat surface to allow a clinician to easily clean and disinfect the first end 101. The first end 101 can be fluidly connected to the second end 103. The first end 101 and the second end 103 can be disposed along the longitudinal length of the connector 100. For example, the first end 101 and the second 103 can be disposed along the 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 (such as a fitting, a connector, a valve, a collar, an accessory, a syringe, 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 connector 100.

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

[0046] In some embodiments, the connector 100 includes a housing 102. The housing 102 may be generally cylindrical in shape and may include a tubing portion 107 and a mating portion 105. The tubing portion 107 may be near the first end 101, and the mating portion 105 may be disposed near the second end 103. The tubing portion 107 may house an end connector 160 that may be configured to couple to a portion of the tubing, allowing the connector 100 to be in fluid communication with that portion of the tubing.

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

[0048] The housing 102 can be substantially cylindrical and can be configured to receive a luer fitting 120. In some embodiments, when the luer fitting 120 is coupled to a coupling device, the coupling device is at least partially disposed within the housing 102. The housing 102 can include a groove 109 that is circumferentially disposed around the housing 102 (such as around the mating portion 105). The groove 109 can be configured to assist a user in rotating the housing 102. In some embodiments, the fitting portion 107 has a maximum diameter greater than that of the mating portion 105. For example, the housing 102 can taper from a first end 101 to a second end 103. In some embodiments, the fitting portion 107 and the mating portion 105 form an integral structure including the housing 102.

[0049] In some embodiments, the housing 102 is configured to receive and accommodate an end connector 160. The end connector 160 can be at least partially disposed within the fitting portion 107. The end connector 160 can be disposed closer to the first end 101 compared to the second end 103. The housing 102 can include a housing ring or collar 110 at the first end 101. The collar 110 can extend radially inwardly from the housing 102. In some embodiments, the collar 110 is one or more protrusions that are circumferentially disposed along the inner surface of the housing 102 and extend radially inwardly. In some embodiments, the collar 110 extends radially inwardly toward the central axis A-A. The housing 102 can be hollow such that the housing 102 can receive and accommodate one or more components. For example, the housing 102 can include an internal space 111 and the collar 110 can extend radially inwardly into the internal space 111. In some embodiments, the collar 110 extends perpendicularly toward the central axis A-A.

[0050] In some embodiments, a second portion of the fitting is terminated by a coupling device (such as coupling device 200) to permit connection and / or disconnection of the second portion of the fitting to a connector 100. In some embodiments, the housing 102 includes features and / or components (such as a luer fitting 120) that permit the connector 100 to be coupled to the coupling device. The coupling device (such as coupling device 200) can be coupled via the fitting to a syringe or a fluid source. In some embodiments, the syringe or fluid source coupled to the coupling device includes a hazardous drug. A hazardous drug can be harmful to an individual if exposed. The connector 100 can be configured to remain connected to the coupling device in response to a pull-out force to prevent separation and exposure of the hazardous drug.

[0051] As can be appreciated, the connector 100 and the coupling device (such as coupling device 200) can be coupled and separated to permit fluid communication as desired. The connector 100 can be coupled to the coupling device 200 to provide a needleless connection. Advantageously, the connector 100 can be mated with the coupling device 200 to form a leak-free closed system that permits delivery of various drugs or fluids.

[0053] Referring Figure 2 - Figure 5 to , the connector 100 may include a housing 102, a sleeve 140, and a luer assembly 180. The luer assembly 180 includes a luer fitting 120 and an end connector 160. The housing 102 may be configured to accommodate the luer assembly 180 and the sleeve 140. For example, the luer assembly 180 and the sleeve 140 may be disposed within the housing 102. The luer assembly 180 may be configured to be at least partially disposed within the sleeve 140 such that the sleeve 140 circumferentially surrounds the luer assembly 180. In some embodiments, the luer assembly 180 includes a passage to permit a fluid path through the luer assembly 180. For example, each of the luer fitting 120 and the end connector 160 may include a passage in fluid communication to permit a fluid path through the luer assembly 180.

[0054] In some embodiments, the luer fitting 120, the sleeve 140, and the end connector 160 are disposed within the housing 102. For example, the luer fitting 120, the sleeve 140, and the end connector 160 may be disposed within an interior space 111 of the housing 102. The luer fitting 120 may be configured to be disposed within the sleeve 140. In some embodiments, the sleeve 140 is circumferentially disposed around the luer fitting 120 such that the sleeve 140 surrounds the luer fitting 120. The end connector 160 may be disposed within the sleeve 140. In some embodiments, the end connector 160 is at least partially disposed within the sleeve 140 and the sleeve 140 is disposed within the housing 102. The luer fitting 120, the sleeve 140, and the end connector 160 may be serially coupled along a central axis A-A. In some embodiments, the luer fitting 120, the sleeve 140, and the end connector 160 are coupled together and disposed within the housing 102 such that the central axis A-A divides each of the housing 102, the luer fitting 120, the sleeve 140, and the end connector 160 into two portions.

[0055] Referring Figure 3, the connector 100 may include a luer member 120 disposed within a housing 102. The luer member 120 may include a first end 121 and a second end 123. The first end 121 may be disposed opposite the second end 123. The luer member 120 may include a coupling portion 124 disposed at the second end 123. In some embodiments, the coupling portion 124 includes threads for coupling to a coupling device. Alternatively, the coupling portion 124 may be coupled to the coupling device via a friction fit, fastener, magnet, or other coupling mechanism. The luer member 120 may include a groove 122 that is disposed proximate the first end 121 and a base 125. The groove 122 may be disposed between the coupling portion 124 and the base 125.

[0056] In some embodiments, the base 125 has a greater diameter than the coupling portion 124, and the coupling portion has a greater diameter than the groove 122. In some embodiments, the coupling portion 124 is tapered. The luer member 120 may taper from the first end 121 to the second end 123. The luer member 120 may be disposed within the housing 102 such that the second end 123 is disposed proximate the second end 103. In some embodiments, the entire luer member 120 is disposed within the housing 102. In some embodiments, the luer member 120 includes one or more slots 126. The slots 126 may be disposed on the base 125. In some embodiments, one or more slots 126 are disposed on the base 125 and are configured to receive one or more protrusions (e.g., protrusion 154) of a sleeve 140.

[0057] Reference Figure 4 , the connector 100 may include a sleeve 140 that may be configured to receive the luer member 120. The sleeve 140 may include a first end 141 and a second end 143, and the second end may be opposite the first end 141. The sleeve 140 may taper from the first end 141 to the second end 143. The sleeve 140 may include a sleeve base 142 disposed at the first end 141. The sleeve base 142 may include protrusions 148 circumferentially disposed along an outer surface of the sleeve base 142. In some embodiments, the sleeve base 142 includes a plurality of protrusions 148 that are equally spaced apart along the sleeve base 142. The sleeve base 142 may include one, two, three, four, or more than four protrusions 148. The protrusions 148 may be configured to engage one or more slots disposed on an inner surface of the housing 102. For example, the housing 102 may include one or more slots (e.g., slot 113) that are configured to receive corresponding protrusions 148.

[0058] The sleeve 140 may include an intermediate portion 144 and a top portion 146. The intermediate portion 144 may be disposed between the sleeve base 142 and the top portion 146. In some embodiments, the sleeve base 142 has a diameter greater than that of the intermediate portion 144. The intermediate portion 144 may have a diameter greater than that of the top portion 146.

[0059] In some embodiments, the sleeve 140 receives the luer member 120 such that the first end 121 of the luer member 120 is disposed adjacent to the first end 141 of the sleeve 140. The luer member 120 may be inserted through the sleeve base 142, extend through the intermediate portion 144, and extend out of the top portion 146 at the second end 143. In some embodiments, when the luer member 120 is disposed within the sleeve 140, the first end 121 of the luer member 120 is disposed within the intermediate portion 144 of the sleeve 140, and the coupling portion 124 extends through and out of the second end 143.

[0060] Reference Figure 5 , the connector 100 may include an end connector 160. The end connector 160 may include a first end 161 and a second end 163 disposed opposite the first end 161. The end connector 160 may include a connector base 165, a ring 166, and a locking ring 170, as well as grooves 164 and 168. The groove 164 may be a base groove configured to receive the housing ring 110. In some embodiments, the groove 164 is disposed between the connector base 165 and the ring 166, and the groove 168 is disposed between the ring 166 and the locking ring 170. The ring 166 may be disposed between the connector base 165 and the locking ring 170. In some embodiments, the ring 166 and the locking ring 170 are one or more protrusions circumferentially disposed and radially extending outward along the outer surface of the end connector 160.

[0061] The connector base 165 and the rings 166 and 170 may extend radially outward from the end connector 160 and may circumferentially surround the end connector 160. In some embodiments, each of the connector base 165 and the rings 166 and 170 has a diameter greater than that of the grooves 164 and 168. The groove 168 may have a greater height than the height of the groove 164. The end connector 160 may include a top portion 169 disposed at the second end 163. In some embodiments, the end connector 160 tapers from the locking ring 170 to the second end 163. The end connector 160 may taper from the first end 161 to the second end 163.

[0062] Figure 6A is in accordance with various aspects of the present disclosure Figure 1A of the bottom perspective view of the connector, wherein the lid is transparent. Figure 6B is in accordance with various aspects of the present disclosureFigure 6A Front perspective view of the connector. Figure 7A is according to various aspects of the present disclosure Figure 1A Cross-sectional view of the connector. Figure 7B is according to various aspects of the present disclosure Figure 7A Enlarged view of the connector. Figure 7C is according to various aspects of the present disclosure Figure 1A Enlarged cross-sectional perspective view of the connector, where the sleeve is secured to the end connector and rotatable relative to the housing.

[0063] In some embodiments, the Luer member 120 includes a passage 127, and the end connector 160 includes a passage 167. The passage 127 and the passage 167 may be disposed along the central axis A-A and may be in fluid communication with each other. The passage 127 may extend through the Luer member 120 to allow fluid to flow through the Luer member 120. In some embodiments, the passage 127 and the passage 167 form a fluid path through the Luer assembly 180 and the connector 100. When a coupling device (such as the coupling device 200) is coupled to the connector 100, a portion of the coupling device may be disposed within the passage 127 to form an airtight or watertight path between the coupling device and the connector 100. The passage 167 may be configured to be in fluid communication with a tubing (such as an IV tubing). For example, the end connector 160 may be configured to be coupled to or integrated with a fluid connection system (such as a tubing) to allow fluid to be transmitted through the connector 100 to a patient.

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

[0065] In some embodiments, the housing 102 includes one or more slots 113 that are adjacent to the location where the fitting portion 107 and the mating portion 105 meet or join. The slots 113 may be provided on the inner or interior surface of the housing 102 and may be located at a position where the diameter of the housing 102 decreases. In some embodiments, when the luer member 120 is disposed within the sleeve 140 and coupled to the end connector 160 and is disposed within the housing 102, the sleeve base 142 is positioned adjacent to the slot 113 such that the protrusion 148 engages and is disposed within the slot 113 to prevent further axial movement of the sleeve 140 toward the second end 123. The luer member 120 coupled to the end connector 160 may form a luer assembly 180 that may be disposed within the sleeve 140.

[0066] In some embodiments, due to the ring 110 being disposed within the groove 164, the luer assembly 180 and the sleeve 140 are disposed and secured within the housing 102. 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. When the luer assembly 180 moves axially toward the first end 103, the ring 110 may deflect or bend. Since 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 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 the disposition of the protrusion within the slot 113 may occur simultaneously with the ring 110 being disposed within the groove 164. The disposition of the protrusion 148 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 disposed within the groove 164 prevents axial movement of the end connector 160 and the luer member 120 relative to the housing 102. In some embodiments, the ring 110 disposed within the groove 164 allows the housing 102 to rotate relative to the end connector 160. The housing 102 may include a plurality of slots 113 corresponding to the number of protrusions 148 of the sleeve 140.

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

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

[0070] In some embodiments, the sleeve 140 includes a protrusion 154 that extends radially inward from the inner surface of the sleeve 140. In some embodiments, the protrusion 154 is a ribbed protrusion. The protrusion 154 may be a ring circumferentially disposed along the inner surface of the sleeve 140 and may be configured to extend radially inward. The luer member 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 over the luer member 120 from the second end 123 to the first end 121. In some embodiments, the slots 132 are formed due to the alignment of the recessed portion of the luer member 120 with the recessed edge 171 of the end connector 160. In other words, a portion of the luer member 120 and a portion of the end connector 160 may form the slots 132. In some embodiments, the sleeve 140 is inserted into the housing 102 such that the protrusion 148 is disposed within or adjacent to the slot 113 to prevent the sleeve 140 from axially moving 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 the luer member 120 (e.g., the 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 a pulling force. 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 since the coupling portion 124 is disposed within the housing 102.

[0072] In some embodiments, the luer member 120 is coupled to the end connector 160 such that the luer member 120 is axially fixed in place relative to the end connector 160. As described above, the top portion 169 may be disposed within the recessed groove 129 such that the end connector 160 is coupled to the luer member 120. The luer member 120 may be coupled to an end connector that may be coupled to the housing 102. For example, the ring 110 of the housing 102 may be disposed within the groove 164 to secure the end connector 160 to the housing 102. The ring 110 of the housing 102 being disposed within the groove 164 results in the end connector 160 being fixed relative to the housing 102. In some embodiments, the luer member 120 is coupled to the end connector 160 and the end connector 160 is coupled to the housing 102, which results in the luer member 120 being axially fixed relative to the end connector 160 and the 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 the first end 101 and the second end 103 of the housing 102. In some embodiments, the coupling of the coupling means to the luer assembly 180 causes the sleeve 140 to move axially relative to the housing 102 and the luer assembly 180.

[0074] In some embodiments, the coupling portion 124 includes threads, such as female threads, that are configured to engage threads (e.g., male threads) of the coupling means to secure the coupling means to the luer member 120 of the luer assembly 180. In some embodiments, the coupling of the coupling means to the luer member 120 causes the sleeve 140 to move axially toward the first end 101 of the housing 102. For example, the coupling means may threadedly engage the coupling portion 124 and rotate downward along the luer member 120 toward the first end 101 such that the coupling means is axially rotated / threaded onto the coupling portion 124 of the luer member 120.

[0075] Reference Figure 7A - Figure 7C, as the coupling device (e.g., coupling device 200) rotates axially downward along the Luer part 120 via the coupling part 124, the coupling device can contact the sleeve 140. Further rotation of the coupling device causes the coupling device to move axially toward the first end 101 and push 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 circumferentially provided 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 when the sleeve 140 is pushed against the locking ring 170, the locking ring 170 bends. For example, when the sleeve 140 moves axially toward the first end 101 of the housing 102, the sleeve 140 can exert a force or pressure on the locking ring 170. The locking ring 170 can bend or deflect to allow the locking ring 170 to be disposed within the groove 152. The locking ring 170 can 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 disposed within the groove 152. When the locking ring 170 is disposed within the groove 152 of the sleeve 140, the sleeve 140 can be axially fixed relative to the Luer assembly 180. In other words, the locking ring 170 being disposed within the groove 152 causes the sleeve 140 to be secured to the end connector 160, which is secured to the Luer part 120 and the housing 102.

[0077] In some embodiments, the locking ring 170 is shaped to allow the sleeve 140 to move past the locking ring 170 toward the first end 101, but not in the opposite direction. The groove 152 can include an edge 149. The locking ring 170 can be circumferentially beveled, and the edge 149 of the sleeve 140 can be circumferentially beveled to allow the locking ring 170 to move past the edge 149 when the sleeve 140 moves toward the first end 101. The locking ring 170 and the edge 149 can be beveled to allow the sleeve 140 to move toward the first end 101, thereby allowing the locking ring 170 to be disposed 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 can be sized and shaped to allow the sleeve 140 to move axially toward the first end 101 such that the locking ring 170 is disposed within the groove 152.

[0078] When the locking ring 170 is disposed within the groove 152, the sleeve 140 can be axially fixed relative to the end connector 160 and the luer fitting 120. For example, once the locking ring 170 is disposed within the groove 152, axial movement of the sleeve 140 toward the first end 101 or the second end 103 can be prevented. Since the coupling device (e.g., coupling device 200) axially urges the sleeve 140 toward the first end 101, the sleeve 140 can axially move toward the first end 101 to dispose the locking ring 170 within the groove 152. This results in the locking ring 170 being disposed within the groove 152. In some embodiments, fully coupling the coupling device to the luer fitting 120 results in the locking ring 170 being disposed within the groove 152.

[0079] Reference Figure 7B - 7C , axial downward movement of the sleeve 140 toward the first end 101 results in the locking ring 170 being disposed within the groove 152, the projection 148 axially moving downward toward the first end 101 within the slot 132, and the projection 154 axially moving downward toward the first end 101 within the slot 113. Axial downward movement of the projection 148 within the slot 132 toward the first end 101 and axial downward movement of the projection 154 within the slot 113 toward the first end 101 cause the sleeve 140 and the luer assembly 180 to be rotatable relative to the housing 102. The housing 102 can include a notch 115. The notch 115 can be disposed adjacent to the slot 113 toward the first end 101 as compared to the second end 103. The notch 115 can partially extend along the slot 113 and can allow the projection 148 to enter and exit the slot 113. In some embodiments, axial downward movement of the projection 148 within the slot 113 toward the first end 101 causes the projection 148 to be disposed adjacent to the notch 115, allowing the projection 148 to rotate out of the slot 113 and thus allowing the housing 102 to be rotatable relative to the sleeve 140.

[0080] Figure 8 is in accordance with various aspects of the present disclosure Figure 1A front view of a connector and a coupling device. Figure 9A is in accordance with various aspects of the present disclosure Figure 1A cross-sectional view of a connector and a coupling device partially coupled to the connector. Figure 9B is in accordance with various aspects of the present disclosure Figure 9A magnified cross-sectional view of a connector. Figure 10A is in accordance with various aspects of the present disclosure Figure 1A cross-sectional view of a connector and a coupling device fully coupled to the connector. Figure 10B is in accordance with various aspects of the present disclosure Figure 10A magnified cross-sectional view of a connector. Figure 11 is in accordance with various aspects of the present disclosure Figure 1AFront perspective view of a connector that is coupled to a coupling device.

[0081] Reference Figure 8 - Figure 11 , the coupling device 200 can be configured to be coupled to the connector 100. The coupling device 200 can be a syringe, a luer fitting, or a tube that is connected to a fluid source. The coupling of the coupling device 200 to the connector 100 results in the formation of a fluid path between the connector 100 and the coupling device 200 to allow fluid to flow from the fluid source through the coupling device 200 and the connector 100 to a patient. In some embodiments, the coupling device 200 is a male luer fitting that is configured to engage with the luer fitting 120. The luer fitting 120 can be a female luer fitting that includes threads and is configured to engage with the coupling device 200.

[0082] The coupling device 200 can include a first end 201 and a second end 203 that is opposite the first end 201. The coupling device 200 can include a base 202 that is disposed at the first end 201 and a body 204 that is disposed near the second end 203. In some embodiments, the coupling device 200 includes a tube 206. The tube 206 can extend from the base 202 and can extend through the body 204. In some embodiments, the tube 206 is in fluid communication with the base 202. The body 204 can be coupled to the base 202 and circumferentially surround the tube 206. The body 204 can include an inner surface having a coupling mechanism. For example, the inner surface of the body 204 can include threads that are configured to engage with the threads of the coupling portion 124 of the luer fitting 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 passage 127 of the luer fitting 120. For example, the coupling of the coupling device 200 to the luer fitting 120 causes the tube 206 to be at least partially disposed within the passage 127 to allow fluid to flow from the fluid source through the tube 206, into the passage 127 and the passage 167, and out of the connector 100.

[0084] Reference Figure 9A - 9B , the coupling device 200 can be rotated to threadedly engage with the luer fitting 120 (e.g., the coupling portion 124). For example, the threads disposed on the inner surface of the body 204 can engage with the threads disposed on the outer surface of the coupling portion 124, causing the coupling device 200 to be coupled to the luer fitting 120 and the tube 206 to be at least partially disposed within the passage 127. In some embodiments, the connector 100 is configured to be in a first configuration ( Figure 9A - 9B ) and a second configuration ( Figure 10A - 10B)。In the first configuration, the coupling device 200 is separated from the connector 100 or is partially coupled to the connector via the luer 120. The coupling device 200 rotates relative to the luer 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 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 120 and pushes the sleeve 140 downward toward the first end 101.

[0085] Reference Figure 9A - 9B , in the first configuration, the locking ring 170 is not disposed within the groove 152 but is disposed closer to the first end 101 compared to the groove 152. The protrusion 154 may be disposed in the slot 132 closer to the luer 120 and the protrusion 148 may be disposed in the slot 113 closer to the second end 103 compared to when the connector 100 is in the second configuration. In the first configuration, the protrusion 148 may not be disposed within the notch 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] Reference Figure 10A - 10B , in the second configuration, the locking ring 170 is disposed within the groove 152. The protrusion 154 may be disposed in the slot 132 closer to the end connector 160 and the protrusion 148 may be disposed in the slot 113 closer to the first end 101 compared to when the connector 100 is in the first configuration. In the second configuration, the protrusion 148 may be disposed within the notch 115, thereby allowing the housing 102 to rotate relative to the sleeve 140. In the second configuration, the sleeve 140 is prevented from axially moving relative to the end connector 160.

[0087] In comparing Figure 9B (the first configuration) and Figure 10B (the second configuration), in Figure 9B , the coupling device 200 does not contact or push against the sleeve 140, resulting in the locking ring 170 not being disposed within the groove 152. When the coupling device 200 is rotated downward and screwed relative to the luer 120 toward the first end 101, the coupling device 200 pushes the sleeve 140 downward, causing the sleeve 140 to axially move relative to the luer assembly 180 and the housing 102. This results in the locking ring 170 being disposed within the groove 152 and the protrusion 148 moving downward in the slot 113 such that the protrusion 148 can engage with the notch 115.

[0088] Reference Figure 11, when the coupling device 200 is fully coupled and fixed to the connector 100 (such as the luer fitting 120) so that the protrusion 148 can engage with the notch 115, the housing 102 is rotatable relative to the sleeve 140 and the luer assembly 180. The 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 the removal of the coupling device 200. For example, in order to separate the coupling device 200 from the luer fitting 120 and thus from the connector 100, the coupling device 200 must be rotated relative to the luer fitting 120. However, in the second configuration, the coupling device 200 is not rotatable relative to the luer fitting 120 because the rotation of the coupling device 200 would cause the rotation of the luer fitting 120. This allows the coupling device 200 to remain connected to the luer fitting 120 and be rotatable relative to the housing 102.

[0089] When the coupling device 200 is fully coupled to the connector 100 (e.g., the second configuration) via the luer fitting 120, 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 fitting 120 and thus from separating the coupling device 200 from the connector 100. For example, since the luer fitting 120 (as well as the sleeve 140 and the end connector 160) is disposed within the housing 102 and the housing 102 is rotatable relative to the luer fitting 120 (as well as the sleeve 140 and the end connector 160), the user cannot rotate the coupling device 200 relative to the luer fitting 120 because the rotation of the coupling device 200 would cause the rotation of the luer fitting 120 when the connector 100 is in the second configuration. In the second configuration, the user cannot rotate the coupling device 200 relative to the luer fitting 120 because the rotation of the coupling device 200 would cause the rotation of the luer fitting 120, which rotates within the housing 102. The user cannot access the luer fitting 120 because the luer fitting is disposed within the housing 102, and thus the user cannot prevent the rotation of the luer fitting 120 when the coupling device 200 is rotated.

[0090] In practice, if the user grasps the housing 102 and attempts to rotate the coupling device 200 relative to the connector 100, the coupling device 200, the luer assembly 180, and the 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 the coupling device 200 prevents the user from separating the coupling device 200 from the connector 100. Additionally, the second configuration of the connector 100 and the coupling device 200 prevents the coupling device 200 from inadvertently separating from the connector 100 in response to an axial force (such as a pull-out force) applied to the connector 100 and / or the coupling device 200.

When the sleeve is coupled to the locking ring, the housing is rotatable relative to the Luer assembly and the sleeve to prevent separation of the Luer assembly from the coupling device when the Luer assembly is coupled to the coupling device.
