Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Serial No. 63 / 439,822, filed on January 18, 2023, entitled CONNECTOR ASSEMBLY WITH DISLODGEMENT PREVENTION, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates generally to connectors, and more particularly to connector assemblies having anti-displacement properties. Background Art

[0004] Medical treatments often involve infusing a patient with a medical fluid (e.g., saline solution or liquid medication) using an intravenous (IV) catheter that 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." Typically, the tubing or catheters are coupled or affixed to one another to allow fluid communication between the various portions of the tubing or catheter.

[0005] In some applications, such pipes or conduits may become dislodged due to improper securing and / or when the connection is subjected to forces greater than the connection was designed to withstand. Utility Model Content

[0006] One or more embodiments of the present disclosure relate to a connector assembly with anti-displacement, comprising: a luer having a first end and a second end opposite to the second end, the luer having a luer body and a luer pin disposed in the luer body, the luer body being configured to move axially relative to the luer pin, wherein the luer has a central axis extending through the first end and the second end; a catheter coupler having an opening and a valve, the catheter coupler being configured to be coupled to the luer so that at least a portion of the luer pin is disposed through the opening and into the valve to form a fluid path between the luer and the catheter coupler; and a connector coupled to the luer so that the luer body is at least partially disposed within the connector, the connector comprising an engagement arm, and the connector having an engaged position and a disengaged position, and being configured to transition from the engaged position to the disengaged position in response to a withdrawal force exceeding a predetermined threshold force. In the engaged position, the engagement arm is positioned proximate the central axis to secure the catheter connector to the Luer to prevent the Luer from being separated from the catheter connector, and in the disengaged position, the engagement arm is pivoted away from the central axis to allow the Luer to be separated from the catheter connector.

[0007] In some embodiments, a withdrawal force exceeding a predetermined threshold force causes the Luer body to move axially along the central axis relative to the Luer pin. The predetermined threshold force may be approximately 5 lb. A withdrawal force exceeding the predetermined threshold force may cause a portion of the connector to move axially relative to the Luer pin.

[0008] In some embodiments, the engagement arm includes a distal end proximate to the first end of the Luer piece, and in the engaged position, the distal end is proximate to the central axis, and in the disengaged position, the distal end is distal to the central axis and pivots away from the catheter coupler when the Luer piece is coupled to the catheter coupler. The connector may include a biasing arm coupled to the engagement arm, the biasing arm being configured to bias the distal end of the engagement arm to be proximate to the central axis.

[0009] In some embodiments, the connector includes a biasing arm coupled to the engagement arm, and the Luer body includes a protrusion disposed proximate to the biasing arm and configured to exert a pushing force on the biasing arm when the extraction force exceeds a predetermined threshold force. In response to the extraction force exceeding the predetermined threshold force, the Luer body can move axially relative to the Luer pin, thereby causing axial movement of the protrusion.

[0010] In some embodiments, a connector assembly with anti-displacement includes a housing having an opening and connected to a Luer piece so that the Luer piece pin extends through the opening and the Luer piece body is close to the opening. The connector may include a base arranged opposite to the distal end of the engagement arm, the base being connected to the housing. When the extraction force exceeds a predetermined threshold, the Luer piece body may move axially relative to the base and the housing. The connector may include a connecting arm that connects the base to the engagement arm, the connecting arm having a retracted position and an extended position and being biased to be in the retracted position. In the engagement position, the connecting arm may be in the retracted position, and in the disengagement position, the connecting arm may be in the extended position. In the disengagement position, the connecting arm may be in the extended position and a pulling force may be applied to the engagement arm, so that the engagement arm is away from the central axis and pivots away from the catheter coupler when the Luer piece is connected to the catheter coupler.

[0011] In some embodiments, the luer includes a biasing element disposed between the luer body and the luer pin, the biasing element biasing the luer body toward the opening of the housing. The luer body includes a protrusion extending from the luer body, and the housing includes a cutout sized and shaped to receive the protrusion, the cutout having a protruding constriction, such that in the engaged position, the protrusion is disposed between the protruding constriction and the cutout, and in the disengaged position, the protruding constriction is disposed between the protrusion and the cutout. The protruding constriction can increase the predetermined threshold force required for the connector to transition from the engaged position to the disengaged position.

[0012] In some embodiments, when the catheter coupler is coupled to the luer and the luer is at least partially disposed within the connector, the central axis bifurcates the luer, the connector, and the catheter coupler.

[0013] In some embodiments, in the disengaged position, the catheter coupler is configured to separate from the luer such that the fluid path is interrupted.

[0014] In some embodiments, the connector assembly with anti-displacement further includes a cover disposed over the luer and the connector, the cover having a slot that allows access to the luer and the connector.

[0015] One or more embodiments of the present disclosure relate to a connector assembly with anti-displacement, comprising: a Luer piece having a first end and a second end opposite to the second end, the Luer piece having a Luer piece body and a Luer piece pin disposed in the Luer piece body, the Luer piece body being configured to move axially relative to the Luer piece pin, wherein the Luer piece has a central axis extending through the first end and the second end, wherein the Luer piece includes a biasing element disposed between the Luer piece body and the Luer piece pin; a housing having an opening and coupled to the Luer piece so that the Luer piece pin extends through the opening and the Luer piece body is proximate to the opening, the biasing element biasing the Luer piece body toward the opening; and a catheter coupler having an opening and a valve, the catheter coupler being configured to be coupled to a luer piece so that at least a portion of the luer piece pin is disposed through the opening and into the valve to form a fluid path between the luer piece and the catheter coupler; and a connector having a base coupled to the housing and a plurality of engagement arms coupled to the base via one or more connecting arms, the connector being coupled to the luer piece so that the luer piece body is at least partially disposed within the connector, the connector having an engaged position and a disengaged position, and being configured to transition from the engaged position to the disengaged position in response to a withdrawal force exceeding a predetermined threshold force, the one or more connecting arms having a retracted position and an extended position, wherein the connecting arms are biased to be in the retracted position. In the engaged position, the connecting arms are in the retracted position, and the plurality of engagement arms are disposed proximate to the central axis to secure the catheter coupler to the luer piece to prevent the luer piece from being separated from the catheter coupler, and in the disengaged position, the one or more connecting arms are in the extended position, and the plurality of engagement arms pivot away from the central axis to allow the luer piece to be separated from the catheter coupler. An extraction force exceeding a predetermined threshold force causes the Luer body to move axially along the central axis relative to the Luer pin and the housing.

[0016] One or more embodiments of the present disclosure are directed to a connector assembly with anti-displacement, comprising: a luer having a first end and a second end opposite to the second end, the luer having a luer body and a luer pin disposed in the luer body, the luer body being configured to move axially relative to the luer pin, wherein the luer has a central axis extending through the first end and the second end, wherein the luer comprises a biasing element disposed between the luer body and the luer pin and a protrusion extending from the luer body; a housing having an opening and coupled to the luer such that the luer pin extends through the opening and the luer body is proximate to the opening, the biasing element biasing the luer body toward the opening; a catheter coupler having an opening and a valve, the catheter coupler being configured to couple to the luer such that at least a portion of the luer pin is disposed through the opening and into the valve to form a fluid path between the luer and the catheter coupler; and a connector coupled to the luer such that the luer body is at least partially disposed within the connector. The connector includes: a base connected to the housing; a plurality of engagement arms, each of which is connected to the base via a plurality of connecting arms, each of the plurality of connecting arms having a retracted position and an extended position, the plurality of connecting arms being biased to be in the retracted position; and a plurality of biasing arms, which connect the plurality of engagement arms together, the plurality of biasing arms being configured to engage one or more protrusions. The connector has an engagement position and a disengagement position, and is configured to switch from the engagement position to the disengagement position in response to a pull-out force exceeding a predetermined threshold force. In the engagement position, the plurality of engagement arms are arranged close to the central axis to fix the catheter connector to the Luer piece to prevent the Luer piece from being separated from the catheter connector, and in the disengagement position, the plurality of connecting arms are in an extended position, the protrusions apply a pushing force to the plurality of biasing arms, and the plurality of engagement arms pivot away from the central axis to allow the Luer piece to be separated from the catheter connector. The pull-out force exceeding the predetermined threshold force causes the Luer piece body to move axially along the central axis relative to the Luer piece pin and the housing.

[0034] The disclosed connector assembly with anti-displacement includes a connector, a Luer piece connected to the connector, and a catheter connector connected to the Luer piece. In some embodiments, the Luer piece extends through the connector. The connector includes a base, which is configured to be connected to a housing to prevent the base from axially moving relative to the housing. The connector includes a first engagement arm and a second engagement arm. The first engagement arm and the second engagement arm are connected to the base via one or more connecting arms. The base of the connector is connected to the housing so that it is fixed in an appropriate position axially relative to the engagement arm and the connecting arm. The first engagement arm is connected to the second engagement arm via one or more biasing arms. The engagement arm is configured to engage the catheter connector. The catheter connector is configured to be connected to the Luer piece so that the engagement arm is connected to the outer surface of the catheter connector, thereby fixing the catheter connector to the Luer piece when the Luer piece is connected to the catheter connector or is disposed in the catheter connector. The engagement arm is configured to prevent the catheter connector from being accidentally separated from the Luer piece.

[0035] The engagement arm has an engagement position and a disengagement position. In the engagement position, the engagement arm is arranged closer to the central axis of the connector assembly than when the engagement arm is in the disengagement position. In the engagement position, the engagement arm is configured to prevent the catheter coupler from being unintentionally or accidentally separated from the Luer piece when the catheter coupler is connected to the Luer piece. The engagement arm is configured to engage the catheter coupler to prevent unintentional axial movement of the catheter coupler relative to the connector. By preventing the axial movement of the catheter coupler relative to the connector, the connector can prevent the catheter coupler from being unintentionally or accidentally displaced from the Luer piece and the connector assembly. The engagement arm can be configured to move from the engagement position to the disengagement position to allow the catheter coupler to be separated from the Luer piece.

[0036] In the disengaged position, the engagement arm is disposed away from the central axis of the connector assembly compared to the engaged position. The engagement arm in the disengaged position allows the catheter coupler to be easily separated from the Luer piece. The engagement arm is configured to switch from the engaged position to the disengaged position in response to a pull-out force exceeding a predetermined threshold force. By allowing the catheter coupler to be separated from the Luer piece in response to a pull-out force exceeding a predetermined threshold force, the catheter coupler can be easily removed by applying an increased pull-out force if necessary. In some embodiments, when the pull-out force does not exceed the predetermined threshold force, the catheter coupler remains fixedly connected to the Luer piece via the engagement arm.

[0037] The detailed description set forth below is intended to be a description of various configurations of the subject technology, and is not intended to represent the unique configuration that can practice the subject technology. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it is clear to those skilled in the art that the subject technology can be implemented without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid confusing the concept of the subject technology. For ease of understanding, similar components are marked with the same element number. Reference numerals may have additional letter suffixes to indicate the individual instances of common elements, and common elements are usually referred to by the same numbering without suffix letters.

[0038] Although the following description is directed to using the disclosed coupling to connect medical accessories 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. The various aspects of the disclosed coupling can be used in any application where it is desired to secure connections of various tubing and accessories.

[0039] The disclosed connector assembly overcomes several challenges found about certain conventional connector assemblies. One challenge of certain conventional connector assemblies is that certain conventional connector assemblies may be difficult to separate from the catheter, which causes the catheter to shift from the patient. In addition, during use, certain conventional connector assemblies may be designed to release or shift in response to relatively low pull-out forces. For example, certain conventional connector assemblies may be released in response to the pull-out force experienced during the patient's turning over in bed, the patient grabbing the tubing or pipeline on the bed rails, moving the patient to a different bed, pediatric patients fidgeting and / or losing their sense of direction to pull out their pipelines. In fact, the 2017 Vascular Access Association (AVA) Annual Scientific Meeting reported that the displacement rate of 1000 patients with peripheral IV catheters was 10%, equivalent to about 33 million displacements per year in the United States alone. Because the accidental or unintentional displacement of tubing, catheters or accessories may interrupt the administration of medical fluids, it is not desirable to use certain conventional connector assemblies.

[0040] Therefore, according to the present disclosure, it is advantageous to provide a connector assembly / coupling as described herein that allows for improved securement of accessories or connectors. The disclosed connector assembly is structured as described herein to permit secure retention of the connector while allowing for deliberate separation and removal of the connector assembly as desired.

[0042] refer to Figure 1A-Figure 3 , a connector assembly or connector assembly 300 with anti-displacement includes a connector 100, a luer piece 200, and a catheter coupler 400. The connector assembly 300 allows a fluid (such as a medical fluid) to flow from a fluid source to a patient by releasably coupling a portion of a tubing or line to another portion of the tubing or line in fluid communication. In the depicted example, portions of the tubing may be terminated with a connector / coupler (such as a first connector 100, a luer piece 200, and / or a catheter coupler 400). The connector 100, the luer piece 200, and / or the catheter coupler 400 may allow for connection and / or disconnection of tubing to allow selective fluid communication therebetween.

[0043] As shown, the first portion of the tubing can be terminated by a catheter coupler 400 to allow the first portion of the tubing to be connected and / or disconnected from the luer 200. The catheter coupler 400 can be configured to cooperate with the luer 200. The catheter coupler 400 can be configured to be coupled to the luer 200 to allow fluid communication between the catheter coupler 400 and the luer 200. In some embodiments, the first portion of the tubing (e.g., a tubing coupled to a catheter inserted in a patient's body) is coupled to the catheter coupler 400, which is configured to be coupled to the luer 200. The luer 200 can be configured to be coupled to the second portion of the tubing (e.g., a tubing coupled to a fluid source). In some embodiments, the luer 200 is coupled to the first portion of the tubing (e.g., a tubing coupled to a catheter inserted in a patient's body), and the catheter coupler 400 is coupled to the second portion of the tubing (e.g., a tubing coupled to a fluid source). The catheter coupler 400 coupled to the luer 200 allows the first portion of the tubing to be in fluid communication with the second portion of the tubing. In some embodiments, when the catheter coupler 400 is coupled to the luer 200, fluid flows from a fluid source through the first portion of the tubing, through the luer 200 and the catheter coupler 400, to the second portion of the tubing and into the patient via the catheter.

[0044] In some embodiments, the catheter coupler 400 is configured to receive at least a portion of the luer 200. For example, a portion of the luer 200 can be inserted into or disposed within the catheter coupler 400 to allow the catheter coupler 400 to be in fluid communication with the luer 200. In some embodiments, the connector 100 is configured to secure the catheter coupler 400 to the luer 200 when the catheter coupler 400 is coupled to the luer 200. When the catheter coupler 400 is coupled to the luer 200, the connector 100 can be configured to secure to the catheter coupler 400 to prevent axial movement of the catheter coupler 400 relative to the luer 200.

[0045] In some embodiments, the catheter coupler 400 includes a first end 401 and a second end 403. The first end 401 can be opposite to the second end 403. The first end 401 can be configured to receive the Luer 200. The first end 401 of the catheter coupler 400 can include an opening 402. The opening 402 can be in fluid communication with the tubing to allow fluid to pass through the catheter coupler 400. In some embodiments, the opening 402 is sized and shaped to receive the Luer 200. The catheter coupler 400 can include a valve 404 configured to control the flow of fluid within the catheter coupler 400. In some embodiments, the valve 404 is at least partially disposed within the opening 402. The valve 404 can be disposed proximate to the first end 401. In some embodiments, the valve 404 is configured to receive or be coupled to the Luer 200 to allow the catheter coupler 400 to be in fluid communication with the Luer 200. The second end 403 of the catheter coupler 400 can be coupled to a catheter or needle via the tubing. The catheter or needle can be inserted into the patient. In some embodiments, valve 404 extends from an area proximate first end 401 to an area proximate second end 403 .

[0046] In some embodiments, the connector assembly 300 includes a luer 200. The luer 200 can be composed of a hard polymer, such as polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), or any other type of hard polymer. The luer 200 can include a luer body 202, a luer pin 210, and an opening 204. The luer 200 can have a central axis AA, and the luer pin 210 can extend at least a portion of the length of the luer 200 along the central axis AA. The luer pin 210 can be disposed within the luer body 202 and can include a channel 213. The channel 213 can be in fluid communication with the opening 204. For example, when the luer 200 is coupled to the catheter coupler 400, fluid can flow from the catheter coupler 400 through the opening 204 and into the channel 213. The luer 200 can be configured to allow fluid communication with the catheter coupler 400 when the luer 200 is coupled to the catheter coupler 400. For example, the opening 402 of the catheter coupler 400 can be configured to receive the luer 200 such that the luer 200 is inserted into the opening 402 of the catheter coupler 400 and the catheter coupler 400 and the luer 200 are in fluid communication. Alternatively, the catheter coupler 400 can be inserted into the opening 204 of the luer 200. When the luer 200 is coupled to the catheter coupler 400, fluid can flow from a fluid source through the luer pin 210 and opening 204 of the luer 200 and through the opening 402 of the catheter coupler 400 to the patient.

[0047] In some embodiments, the opening 402 of the catheter coupler 400 and / or the opening 204 of the Luer piece 200 include one or more features that allow the opening 402 to cooperate with the opening 204. The opening 204 and / or the opening 402 can be an inlet and / or an outlet. The opening 204 of the Luer piece 200 can be assembled together with the opening 402 of the catheter coupler 400 or otherwise engaged to allow the fluid communication between the catheter coupler 400 and the Luer piece 200 and the tubing part connected thereto. As can be understood, the catheter coupler 400 and the Luer piece 200 can be connected and separated to allow fluid communication according to expectations. As shown in the figure, the opening 204 can include an outer portion, which is smooth and has no threads. In some embodiments, the opening 204 can include an outer portion, which includes threads, so as to be connected with the catheter coupler 400. The catheter coupler 400 can be connected with the Luer piece 200 to provide a needleless connection. Advantageously, catheter coupler 400 may mate with luer 200 to form a leak-free closed system, thereby allowing for the delivery of various fluids, medications, and / or liquids.

[0048] The luer 200 can be sized and shaped to mate with the opening 402 of the catheter coupler 400. In some embodiments, when the luer 200 is coupled to the catheter coupler 400, a fluid path is formed from a fluid source via the opening 204 through the luer 200 and via the opening 402 through the catheter coupler 400 to a catheter coupled to a patient. In some embodiments, the catheter coupler 400 is coupled to the luer body 202 of the luer 200. The catheter coupler 400 can be coupled to the luer body 202 to allow the opening 402 to be in fluid communication with the luer pin 210 and the channel 213. In some embodiments, the luer pin 210 includes a valve (e.g., valve 214) configured to control the flow of fluid within the luer 200. For example, the valve 214 can be configured to control the flow of fluid within the channel 213 of the luer pin 210.

[0049] refer to Figure 2A-2B , the luer 200 can be coupled to the housing 500. The housing 500 can be coupled to a portion of a tubing, a portion of which can be coupled to a fluid source. The housing 500 can be made of a hard polymer, such as polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS) or any other type of hard polymer. In some embodiments, the housing 500 includes a channel 506 that is in fluid communication with the opening 204 of the luer 200 and the luer pin 210. The channel 506 can be configured to receive a portion of the tubing or allow fluid communication between a portion of the tubing and the luer 200. In some embodiments, the housing 500 includes an opening 511 that is configured to receive a portion of the luer pin 210. At least a portion of the luer pin 210 can be disposed within the luer body so that the luer body 202 abuts or contacts the opening 511 of the housing 500. The housing 500 can include a channel 506 that can be in fluid communication with the luer channel 213.

[0050] In some embodiments, the channel 506 receives a portion of the luer pin 210 and allows the luer 200 to be in fluid communication with a portion of the tubing. In some embodiments, the luer pin 210 is disposed within and extends from the luer body 202 (e.g., opposite the opening 204) such that the luer pin 210 extends into the channel 506 of the housing 500. The luer body 202 can contact, abut, or be disposed proximate to the opening 511 of the channel 506. The luer pin 210 can be coupled to or partially disposed within the channel 506 such that the channel 506 is in fluid communication with the luer pin 210. In some embodiments, the luer pin 210 is at least partially affixed within the channel 506, thereby preventing axial movement of the luer pin 210 relative to the housing 500.

[0051] In some embodiments, the luer body 202 is configured to move axially relative to the luer pin 210. The luer pin 210 can be coupled to the housing 500 and can be at least partially disposed within the luer body 202. In some embodiments, the luer pin 210 is fixed to the housing 500, and the luer body 202 is configured to move axially relative to the luer pin 210 and / or the housing 500. The luer 200 can include a cavity 217 and can include a biasing element 211 disposed within the cavity 217. In some embodiments, at least a portion of the luer pin 210 is disposed within the cavity 217 of the luer body 202. The biasing element 211 can be configured to bias the luer body 202 toward the housing 500. The biasing element 211 can include one end coupled to the housing 500 (e.g., near the opening 511) and another end coupled to the luer body 202 (e.g., located within the cavity 217). In some embodiments, when the catheter connector 400 is coupled to the luer 200 and pulled axially away from the housing 500, the biasing element 211 can stretch (e.g., extend) as the luer body 202 moves axially away from the housing 500 relative to the luer pin 210.

[0052] The luer 200 can include a biasing element 211. The biasing element 211 can be disposed within the interior of the luer body 202. In some embodiments, the biasing element 211 is disposed between the luer pin 210 and the inner surface of the luer body 202. The biasing element 211 can be configured to allow axial movement of the luer body 202 relative to the luer pin 210. The biasing element 211 can be configured to bias the luer body 202 toward the housing 500. The luer body 202 can move axially along the central axis AA relative to the luer pin 210. For example, the luer body 202 can move axially from adjacent to the opening 511 of the channel 506 to away from the opening 511 relative to the luer pin 210. However, the biasing element 211 can be configured to bias the luer body 202 back to adjacent to the opening 511 of the channel 506 of the housing 500.

[0053] The luer 200 may include one or more protrusions 206. In some embodiments, the luer 200 includes two protrusions 206 disposed on the luer body 202 of the luer 200. The protrusions 206 may be disposed opposite each other. The luer 200 may include one, three, four, or more than four protrusions 206. In some embodiments, the protrusions 206 extend away from the luer body 202 perpendicular to the central axis AA. The protrusions 206 may move axially due to axial movement of the luer body 202. For example, the luer body 202 may move axially away from the housing 500 relative to the luer pin 210, which may cause the protrusions 206 to move axially away from the housing 500. The protrusions 206 may be substantially circular.

[0054] In some embodiments, movement of the luer body 202 away from the opening 511 and relative to the luer pin 210 causes the valve 214 within the luer pin 210 to close to prevent fluid from leaking or spilling from the luer pin 210 into the luer body 202 or outside the luer body 200. For example, when the luer body 202 is pulled axially away from the housing 500 (e.g., due to the catheter coupler 400 being pulled), the valve 214 can close the luer pin 210 to prevent fluid from entering or leaving the luer 200.

[0055] In some embodiments, the luer 200 includes a valve (e.g., valve 214) to allow fluid to pass therethrough when the luer 200 is coupled to the catheter coupler 400, and is configured to prevent or restrict flow when the luer 200 is disconnected from the catheter coupler 400. In some embodiments, the luer 200 includes a sealing valve (e.g., valve 214) to seal the flow path between the luer pin 210 and the opening 204 when the luer 200 is disconnected from the catheter coupler 400. When the catheter coupler 400 is coupled to the luer 200 (e.g., in fluid communication with the luer pin 210), the sealing valve can be moved to an open position, thereby allowing flow between the luer 200 and the catheter coupler 400.

[0056] Similarly, the catheter coupler 400 can include a sealing valve (e.g., valve 404) to allow fluid to pass therethrough when the catheter coupler 400 is coupled to the luer 200, and is configured to prevent or restrict flow when the catheter coupler 400 is disconnected from the luer 200. The catheter coupler 400 includes a sealing valve (e.g., valve 404) to seal flow out of the outflow opening 402 when the catheter coupler 400 is separated from the luer 200. In addition, when the luer 200 is coupled to the catheter coupler 400, the sealing valve can be moved to an open position to allow flow between the catheter coupler 400 and the luer 200 (e.g., luer pin 210). In some embodiments, the sealing valve is formed of silicone.

[0057] In some embodiments, the housing 500 includes a ring 502, a recessed collar 503, and one or more fins 504. The recessed collar 503 may be disposed between the ring 502 and the fins 504. In some embodiments, the ring 502 is disposed closer to the passage 506 and / or the opening 511 than the fins 504. The ring 502 may have a maximum diameter that is greater than the maximum diameter of the recessed collar 503. The housing 500 may further include a frustoconical or tapered portion 507 and a body 505. The tapered portion 507 may be disposed between the body 505 and the recessed collar 503. The body 505 may extend from the tapered portion 507 and may have a smaller maximum diameter than the recessed collar 503. The tapered portion 507 may have a decreasing diameter from a portion close to the recessed collar 503 to a portion close to the body 505. In some embodiments, the fins 504 are disposed on the body 505. A portion of the luer 200 can be at least partially disposed within the body 505 and can extend into the passage 506. For example, a portion of the luer pin 210 can be disposed within the body 505. In some embodiments, the housing 500 includes a cutout 508 that is sized and shaped to receive the protrusion 206 of the luer 200. The housing 500 can include any number of cutouts 508 corresponding to the number of protrusions 206 of the luer 200.

[0058] In some embodiments, the connector 100 includes a base 102 and is coupled to the housing 500 (e.g., via the base 102). The recessed collar 503 can be configured to receive and secure the base 102 of the connector 100. For example, the recessed collar 503 can be sized and shaped so that the base 102 can be disposed around the recessed collar 503 to secure the base 102 to the housing 500. In some embodiments, the base 102 is secured to the housing 500 by being disposed around the recessed collar 503 and disposed between the tabs 504 and the ring 502. For example, the base 102 disposed between the ring 502 and the tabs 504 can prevent axial movement of the base 102 relative to the housing 500 (e.g., movement along the central axis AA). In some embodiments, the base 102 is secured to the recessed collar 503 via an adhesive, a magnet, a hook, or any other type of coupling element.

[0059] In some embodiments, a portion of the luer 200 (e.g., the luer pin 210) and a portion of the connector 100 (e.g., the base 102) are coupled to the housing 500 such that the luer 200 is disposed within the connector 100. For example, a portion of the luer 200 may be disposed within / coupled to the housing 500, and the base 102 of the connector 100 may be coupled to the housing 500 such that at least a portion of the luer 200 (e.g., the luer body 202) extends through the connector 100. The luer pin 210 may be coupled to the housing 500, and the luer body 202 may be configured to move axially relative to the luer pin 210 and the housing 500. In some embodiments, when a portion of the luer 200 is coupled to the housing 500, the central axis AA extends longitudinally along the length of the luer 200 and the housing 500. The connector 100 may be configured to at least partially radially surround the luer 200 and the central axis AA.

[0060] refer to Figure 1A-Figure 3 , the connector 100 may include a first end 101 and a second end 103. The central axis AA may extend through the first end 101 and the second end 103. In some embodiments, the central axis AA divides the Luer piece 200 and the connector 100 into two parts. The connector 100 may be composed of a flexible material and may be composed of an integral structure. For example, the connector 100 may be composed of a soft, flexible material (such as silicone or rubber). The connector 100 may include a base 102 and may be configured to be coupled to the housing 500 (e.g., via the base 102) and extend away from the housing 500. In some embodiments, a portion of the connector 100 is configured to move axially away from and / or toward the housing 500 along the central axis AA.

[0061] The connector 100 may include a base 102, a first connecting arm 104, a second connecting arm 105, a first engaging arm 106, and a second engaging arm 108. Figure 1A-Figure 3A connector 100 having two connecting arms and two engaging arms is shown, but the connector 100 may have one, three, four, or more than four connecting arms and / or engaging arms. The connecting arms 104, 105 may extend from the base 102. In some embodiments, the connecting arms 104, 105 are configured to move relative to the base 102. For example, the base 102 may be coupled to the housing 500 and fixed in position relative to the connecting arms 104, 105. The connecting arms 104, 105 may be configured to contract toward the base 102 and extend away from the base 102. In some embodiments, the connecting arm 104 is coupled to the base 102, opposite to the position where the connecting arm 105 is coupled to the base 102. The connecting arms 104, 105 may be disposed between the base 102 and the engaging arms 106, 108 near the first end 101. The first connecting arm 104 may be configured to extend from the base 102 to couple to the first engagement arm 106, and the second connecting arm 105 may be configured to extend from the base 102 and couple to the second engagement arm 108. In some embodiments, the first engagement arm 106 extends from the first connecting arm 104 to an area near the second end 103, and the second engagement arm 108 extends from the second connecting arm 106 to an area near the second end 103. In some embodiments, the first engagement arm 106 extends from the first connecting arm 104 to be substantially parallel to the second engagement arm 108 extending from the second connecting arm 105.

[0062] In some embodiments, the first connecting arm 104 and the second connecting arm 105 extend from the base 102 in a spiral configuration. For example, the first connecting arm 104 can spiral from the base 102 in a counterclockwise manner, and the second connecting arm 105 can extend from the base 102 in a clockwise manner. The first connecting arm 104 and the second connecting arm 105 can be configured to bias the first engagement arm 106 and the second engagement arm 108 toward the base 102. In some embodiments, the first connecting arm 104 is configured to bias the first engagement arm 104 toward the base 102, and the second connecting arm 105 is configured to bias the second engagement arm 106 toward the base 102. The engagement arms 106, 108 can be disposed between the second end 103 and the connecting arms 104, 105. The connecting arms 104, 105 can allow the engagement arms 106, 108 to move axially relative to the base 102 and / or the housing 500 along the central axis AA. For example, the connecting arms 104, 105 may extend away from or retract toward the base 102, thereby causing movement of the engagement arms 106, 108. The base 102, connecting arms 104, 105, and engagement arms 106, 108 may form a unitary structure.

[0063] In some embodiments, the first connecting arm 104 is coupled to the first engagement arm 106 at a connection point 121, and the second connecting arm 105 is coupled to the second engagement arm 108 at a connection point 123. The first connection point 121 can be disposed on the first engagement arm 106 proximate to the first end 101, and the second connection point 123 can be disposed on the second engagement arm 108 proximate to the second end 103. The first engagement arm 106 can include a first distal end 110, which can be opposite to the first connection point 121. In some embodiments, the first distal end 110 is proximate to the first end 101. The second engagement arm 108 can include a second distal end 112, which can be opposite to the second connection point 123. In some embodiments, the second distal end 112 is proximate to the first end 101.

[0064] The connecting arms 104, 105 can be configured to be in a retracted state or in an extended state. The connecting arms 104, 105 can be biased to be in a retracted position so that when the connecting arms 104, 105 are in the extended position, they apply a pulling force to the engagement arms 106, 108. In the retracted state, the first connecting arm 104 does not apply a pulling force to the first engagement arm 106 at the connection point 121, and the second connecting arm 105 does not apply a pulling force to the second engagement arm 108 at the connection point 123. In the extended state, the first connecting arm 104 applies a pulling force to the first engagement arm 106 at the connection point 121, and the second connecting arm 105 applies a pulling force to the second engagement arm 108 at the connection point 123.

[0065] In some embodiments, the connector 100 includes one or more biasing arms 115. The biasing arms 115 can be configured to couple the first engagement arm 106 to the second engagement arm 108. The connector 100 can include two biasing arms 115 disposed opposite each other. However, the connector 100 can include any number of biasing arms 115. The biasing arms 115 can be biased to keep the first engagement arm 106 substantially parallel to the second engagement arm 108 and to keep the first engagement arm 106 and the second engagement arm 108 close to the central axis AA.

[0066] In some embodiments, when the Luer body 202 moves axially along the central axis AA away from the housing 500, the protrusion 206 abuts against and pushes against the biasing arm 115. The protrusion 206 pushing against the biasing arm 115 can cause the connecting arms 104, 105 to stretch (e.g., stretch outward) away from the base 102. For example, in response to the extraction force (e.g., force F) exceeding a predetermined threshold force, the Luer body 202 can move axially along the central axis AA away from the housing 500, thereby causing the protrusion 206 to apply a pushing force against the biasing arm 115. The extension of the connecting arms 104, 105 can cause a pulling force to be applied to the engagement arms 106, 108, thereby pulling the engagement arms 106, 108 toward the base 102. The distal ends 110, 112 can be configured to move away from the central axis AA in response to the pushing force of the protrusion 206 against the biasing arm 115 and the pulling force of the connecting arms 104, 105 on the engagement arms 106, 108. In other words, the engagement arms 106, 108 can pivot away from the central axis AA in response to the protrusion 206 pushing against the biasing arm 115 and the connecting arms 104, 105 extending and pulling the engagement arms 106, 108 toward the base 102.

[0067] Figure 4A yes Figure 1A A side perspective view of the connector assembly in an engaged position, and Figure 4B yes Figure 2A A side perspective view of the connector assembly in a disengaged position.

[0068] refer to Figure 4A-4B , the connector 100 may have an engaged position ( Figure 4A ) and disengaged position ( Figure 4B ). In the engaged position, the first distal end 110 of the first engagement arm 106 and the second distal end 112 of the second engagement arm 108 can be disposed proximate to the central axis AA, and the first engagement arm 106 can be disposed substantially parallel to the second engagement arm 108. When the connector 100 is in the engaged position and the catheter coupler 400 is coupled to the luer body 202, the engagement arms 106, 108 can be configured to contact the catheter coupler 400 and substantially prevent axial movement of the catheter coupler 400 relative to the luer body 202 and / or the connector 100.

[0069] In some embodiments, engagement arms 106, 108 include gripping features 119. Gripping features 119 can be configured to secure catheter coupler 400 to luer 200 when catheter coupler 400 is coupled to luer 200 and connector 100 is in the engaged position. In some embodiments, first engagement arm 106 and second engagement arm 108 each include one or more gripping features 119. Gripping features 119 prevent catheter coupler 400 from being separated from luer 200 when engagement arms 106, 108 are in the engaged position.

[0070] In the engaged position, the connector 100 can prevent unintentional separation of the catheter coupler 400 from the luer body 202 by contacting an outer surface of the catheter coupler 400 and preventing movement of the catheter coupler 400 relative to the luer body 202. When the connector 100 is in the disengaged position, the engagement arms 106, 108 can be disposed away from the central axis AA and away from the luer body 202, resulting in the engagement arms 106, 108 not contacting or abutting contacting the catheter coupler 400 when the catheter coupler 400 is coupled to the luer body 202. In the disengaged position, the catheter coupler 400 can be easily separated from the luer body 202.

[0071] The connector 100 can be configured to switch from the engaged position to the disengaged position in response to a pull-out force exceeding a predetermined threshold force. For example, when the catheter coupler 400 is coupled to the Luer body 202, a pull-out force (e.g., force F) can be applied to the catheter coupler. Since the catheter coupler 400 is coupled to the Luer body 202, the pull-out force can cause the Luer body 202 to move axially relative to the housing 500. In some embodiments, the pull-out force (e.g., force F) causes the Luer body 202 to move axially relative to the housing 500 only when the pull-out force exceeds the predetermined threshold force. When the pull-out force does not exceed the predetermined threshold force, the connector 100 may not switch from the engaged position to the disengaged position.

[0072] In some embodiments, the connector 100 moves from the engaged position (eg, force F) due to the axial movement of the Luer body 202 in response to the extraction force (eg, force F). Figure 4A ) to the disengaged position ( Figure 4B). When a force F applied to the luer body 202 (e.g., via the catheter coupler 400) is greater than a predetermined threshold force, the connector 100 can be transitioned from the engaged position to the disengaged position. The luer 200 can be coupled to a fluid source via a first tube coupled to the housing 500 (e.g., and the luer pin 210), and the luer body 202 can be coupled to the catheter coupler 400, which can be coupled to the patient via a second tube. A force can be applied to the first tube, such as pulling on tubing coupled to the catheter coupler 400 and / or the luer 200. If the catheter coupler 400 remains coupled to the luer body 202 and the luer 200, the applied force can be transmitted to the patient.

[0073] In some embodiments, separating the luer body 202 from the catheter coupler 400 prevents the applied force from being transferred to the patient and prevents unintentional injury to the patient (e.g., pulling on a catheter or needle coupled to the coupler 400 and inserted into the patient). When a force (e.g., force F) exceeds a predetermined threshold force, the connector 100 can be configured to separate the catheter coupler 400 from the luer 200, thereby preventing the force F from being applied to the patient or to a catheter / needle inserted into the patient.

[0074] Figure 4A The connector 100 is shown in the engaged position in response to the force F being less than or equal to a predetermined threshold force applied to the luer body 202. For example, the connector 100 may be subjected to forces due to a patient rolling over in bed, a patient grabbing tubing or lines on a bed rail, moving a patient to a different bed, a pediatric patient fidgeting, and / or a disoriented adult patient pulling on their lines. According to various embodiments of the present disclosure, when subjected to lower forces (e.g., force F is less than or equal to a predetermined threshold force), the connector 100 can be configured to be in the engaged position to hold the catheter coupler 400 and the luer 200 together so that the fluid path remains open and fluid (e.g., IV fluid) can be administered from a fluid source (e.g., a fluid bag, an IV bag, a fluid container, etc.) through the luer 200 to the catheter coupler 400 and the patient.

[0075] Figure 4B The disengaged position of the connector 100 is depicted when the force F exceeds a predetermined threshold force applied to the luer body 202. According to various embodiments of the present disclosure, when subjected to a higher force (e.g., a force F exceeding the predetermined threshold force), the connector 100 can be configured to move to the disengaged position, thereby releasing or otherwise separating the catheter coupler 400 from the luer body 202, at which point the fluid path between the luer pin 210 and the catheter coupler 400 can be closed, and medical fluid (e.g., IV fluid) can cease to enter the catheter coupler 400 and / or the luer pin 210.

[0076] In some embodiments, the predetermined threshold force can be about 5 pounds (lb). For example, if a patient coupled to the catheter coupler 400 (e.g., via a needle inserted into the skin) moves away from a fluid source or accidentally pulls on a tubing coupled to the fluid source and the force exceeds 5 lb, the connector 100 can automatically move from the engaged position to the disengaged position, thereby allowing the catheter coupler 400 to release or separate from the luer body 202, effectively closing the fluid path connecting the patient to the fluid source (e.g., via the catheter coupler 400 and the luer 200). The predetermined threshold force can be from about 1 lb to about 10 lb, about 2 lb to about 8 lb, about 3 lb to about 6 lb, or greater than 10 lb. A connector 100 that releases or otherwise separates the catheter coupler 400 from the luer body 202 is superior to conventional connectors, which may not result in release or separation, thereby causing bleeding, drug leakage, or other injuries.

[0077] In some embodiments, a force F exceeding a predetermined threshold force causes axial movement of the Luer body 202 relative to the Luer pin 210 and the housing 500, which causes axial movement of the protrusion 206 along the central axis AA. The force F exceeding the predetermined threshold force can cause axial movement of the Luer body 202 relative to the Luer pin 210, which can cause the valve within the Luer pin 210 to close and prevent any fluid from flowing into or out of the Luer pin 210. The axial movement of the protrusion 206 can cause the protrusion 206 to abut the biasing arm 115 and apply a force (e.g., force F) thereto. The axial movement of the protrusion 206 against the biasing arm 115 can also cause the connecting arms 104, 105 to apply a pulling force to the engagement arms 106, 108 at the connection points 121, 123, respectively.

[0078] The pulling force can cause the biasing arm 115 to be pulled around the circumference of the protrusion 206, thereby causing the engagement arms 106, 108 to pivot away from the Luer body 202 and the central axis AA. Since the connecting arms 104, 105 are coupled to the base 102, which is fixed relative to the Luer body 202, the connecting arms 104, 105 can apply a pulling force to the engagement arms 106, 108, respectively. Therefore, when the Luer body 202 moves axially away from the base 102, the connecting arms 104, 105 transition from a retracted position to an extended position, thereby causing a pulling force to be applied to the engagement arms 106, 108 at the connection points 121, 123, respectively. The pulling force applied by the connecting arms 104, 105 also causes the biasing arm 115 to stretch around the protrusion 206, which causes the engagement arms 106, 108 to pivot away from the Luer body 202 and the central axis AA. The engagement arms 106, 108 pivoting away from the central axis AA cause the connector 100 to move from the engaged position to the disengaged position. The predetermined threshold force may be based on the flexibility or stiffness of the biasing arm 115 and the connecting arms 104, 105. For example, the higher the stiffness of the biasing arm 115 and the connecting arms 104, 105, the greater the predetermined threshold force.

[0079] In practice, the catheter coupler 400 can be coupled to the Luer 200, and the connecting arms 104, 105 can be in a retracted position, thereby causing the engagement arms 106, 108 to be in an engaged position and thus securing the catheter coupler 400 to the Luer 200. The engagement arms 106, 108 can prevent accidental separation of the catheter coupler 400 from the Luer 200. When a force (e.g., force F) that does not exceed a predetermined threshold force is applied to the Luer 200, the connector 100 can remain in the engaged position due to the coupling of the catheter coupler 400 to the Luer body 202. For example, a smaller force (e.g., a force less than the predetermined threshold force) can be applied to the Luer 200 (or a tube coupled to the Luer 200). These smaller forces may not cause the connector 100 to transition from the engaged position to the disengaged position because the force applied by the protrusion 206 to the biasing arm 115 is insufficient to transition the connecting arms 104, 105 from the retracted state to the extended state. This maintains the catheter coupler 400 secured to the luer body 202 via the engagement arms 106 , 108 .

[0080] When the force F applied to the luer 200 exceeds the predetermined threshold force, the protrusion 206 can exert a force on the biasing arm 115, thereby causing the connecting arms 104, 105 to change from the retracted state to the extended state, thereby causing the engagement arms 106, 108 to pivot away from the central axis AA, causing the connector 100 to change from the engaged position to the disengaged position, and allowing the catheter coupler 400 to be separated from the luer 200. In some embodiments, because the connecting arms 104, 105 are biased toward the base 102 and the base 102 is fixed relative to the connecting arms 104, 105 and the biasing arm 115, the biasing arm 115 of the connector 100 is biased to press against the protrusion 206.

[0081] refer to Figure 2A , the connector 100 may include a shroud 150. The shroud 150 may extend from the first engagement arm 106 to the second engagement arm 108. In some embodiments, the shroud 150 is coupled to the biasing arm 115. The shroud 150 may cover a portion of the luer body 202 and may be configured to provide protection to the luer body 202. In some embodiments, the shroud 150 is comprised of an overmolded elastomer.

[0082] Figure 5A is a perspective view of a connector assembly with a mechanical constriction according to various aspects of the present disclosure. Figure 5B yes Figure 5A A side view of a coupling assembly.

[0083] refer to Figure 5A-Figure 5B , the housing 500 may include a notch 520. The notch 520 may be a bump, a ramp, or a protrusion disposed on the cutout 508. In some embodiments, the protrusion 206 is disposed within the cutout 508, and the notch 520 is disposed proximate to the cutout 508. When the protrusion is disposed within the cutout 508, the notch 520 may be disposed distal to the ring 502 compared to the protrusion 206. The notch 520 may be configured to increase the force (e.g., force F) required to cause the axial movement of the protrusion 206 and thus cause the connector 100 to transition from the engaged position to the disengaged position. In some embodiments, the presence of the notch 520 increases a predetermined threshold force of the force F that needs to be exceeded to cause the connector 100 to transition from the engaged position to the disengaged position. The housing 500 may include any number of notches 520. For example, the housing 500 may include a total of one, two, three, four, or more than four notches 520. In some embodiments, the greater the number of constrictions, the greater the predetermined threshold force of the force F required to transition the connector 100 from the engaged position to the disengaged position.

[0084] In some embodiments, the luer 200 includes a securing arm 220. The securing arm 220 can be configured to facilitate coupling the catheter coupler 400 to the luer 200. For example, when the catheter coupler 400 is secured to the luer 200, the securing arm 220 can be configured to engage or abut a portion of the catheter coupler 400 to secure the catheter coupler 400 to the luer 200. In some embodiments, when the force F exceeds a predetermined threshold force, at least a portion of the securing arm 220 pivots or moves toward the central axis AA, thereby allowing the catheter coupler 400 to be separated from the luer 200 when the force F exceeds the predetermined threshold force.
