Abstract
Description
[Technical Field]
[0001] This application claims the benefit of priority under 35 U.S.C. § 119 to U.S. Provisional Patent Application Serial No. 63 / 439,822, entitled "CONNECTOR ASSEMBLY WITH DISLODGEMENT PREVENTION," filed January 18, 2023, the entire contents of which are incorporated herein by reference.
[0002] The present disclosure relates generally to connectors, and more particularly to a connector assembly having anti-slip features. [Background technology]
[0003] Medical procedures often involve infusing a patient with medical fluids (e.g., saline or liquid medications) 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." Often, the tubing or catheter is connected or secured to one another to allow fluid communication between various portions of the tubing or catheter.
[0004] In some applications, such tubing or catheters can become dislodged due to improper fixation and / or when the connection is subjected to forces greater than the connection is designed to withstand. Summary of the Invention [Means for solving the problem]
[0005] One or more embodiments of the present disclosure relate to a connector assembly including: a luer having a first end and a second end opposite the first end, the luer having a luer body and a luer pin disposed within the luer body, the luer body configured to move axially relative to the luer pin, the luer having a central axis passing through the first end and the second end; a catheter coupler having an opening and a valve, the catheter coupler configured to couple to the luer such that at least a portion of the luer pin is disposed through the opening and within the valve to form a fluid pathway 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 including an engagement arm, the connector having an engaged position and a disengaged position, and 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 near the central axis to secure the catheter coupler to the luer and prevent separation of the luer from the catheter coupler, and in the disengaged position, the engagement arm is pivoted away from the central axis to allow separation of the luer from the catheter coupler.
[0006] In some embodiments, a withdrawal force exceeding a predetermined threshold force causes axial movement of the luer body relative to the luer pin along the central axis. The predetermined threshold force can be approximately 5 lbs. A withdrawal force exceeding the predetermined threshold force can cause a portion of the connector to move axially relative to the luer pin.
[0007] In some embodiments, the engagement arm includes a distal end near the first end of the luer, and in the engaged position, the distal end is near the central axis and in the disengaged position, the distal end is pivoted away from the central axis and, if the luer is coupled to a catheter coupler, away from the catheter coupler. The connector can include a biasing arm coupled to the engagement arm, the biasing arm configured to bias the distal end of the engagement arm closer to the central axis.
[0008] In some embodiments, the connector includes a biasing arm coupled to the engagement arm, and the luer body includes a protrusion disposed proximate the biasing arm and configured to apply a biasing force to the biasing arm when the withdrawal force exceeds a predetermined threshold force, and in response to the withdrawal force exceeding the predetermined threshold force, the luer body can move axially relative to the luer pin to cause axial movement of the protrusion.
[0009] In some embodiments, the connector assembly includes a housing having an opening, the housing being coupled to the luer such that the luer pin extends through the opening and the luer body is proximate the opening. The connector can include a base disposed opposite the distal end of the engagement arm, the base being coupled to the housing. When a withdrawal force exceeds a predetermined threshold force, the luer body can move axially relative to the base and the housing. The connector can include a connecting arm connecting the base to the engagement arm, the connecting arm having a retracted position and an extended position, the connecting arm being biased to be in the retracted position. In the engaged position, the connecting arm can be in the retracted position, and in the disengaged position, the connecting arm can be in the extended position. In the disengaged position, the connecting arm can be in the extended position, and applying a pulling force to the engagement arm pivots the engagement arm away from the central axis and, if the luer is coupled to the catheter coupler, away from the catheter coupler.
[0010] 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 in the housing. The luer body includes a protrusion extending therefrom, and the housing includes a cutout sized and shaped to receive the protrusion, the cutout having a raised indent such that in the engaged position, the protrusion is disposed between the raised indent and the cutout, and in the disengaged position, the raised indent is disposed between the protrusion and the cutout. The raised indent can increase the predetermined threshold force required to transition the connector from the engaged position to the disengaged position.
[0011] In some embodiments, when the catheter coupler is coupled to the luer and the luer is at least partially disposed within the connector, a central axis bisects the luer, the connector, and the catheter coupler.
[0012] In some embodiments, in the disengaged position, the catheter coupler is configured to disconnect from the luer, thereby interrupting the fluid pathway.
[0013] In some embodiments, the connector assembly of claim 1 further comprises a cover disposed over the lure and the connector, the cover having a slot allowing access to the lure and the connector.
[0014] One or more embodiments of the present disclosure include a connector assembly, the connector assembly including: a luer having a first end and a second end opposite the first end, the luer having a luer body and a luer pin disposed within the luer body, the luer body configured to move axially relative to the luer pin, the luer having a central axis passing through the first end and the second end, the luer including a biasing element disposed between the luer body and the luer pin; a housing having an opening, the housing coupled to the luer such that the luer pin extends through the opening and the luer body is proximate the opening, the biasing element biasing the luer body toward the opening; and a catheter coupler having an opening and a valve, the catheter coupler including the luer a catheter coupler configured to couple to a luer such that at least a portion of a pin is disposed through an opening in a valve to form a fluid pathway between the luer and the catheter coupler; and a connector having a base coupled to a housing and a plurality of engagement arms connected to the base by one or more connection arms, the connector coupled to the luer such that a luer body is at least partially disposed within the connector, the connector having an engaged position and a disengaged position and 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 connection arms having a retracted position and an extended position, the connection arms being biased to be in the retracted position.

[0019] The disclosed connector assembly includes a connector, a luer coupled to the connector, and a catheter coupler coupled to the luer. In some embodiments, the luer extends through the connector. The connector includes a base configured to couple to the housing and prevent axial movement of the base 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 coupled to the base by one or more connecting arms. The connector base is coupled to the housing such that the base is axially fixed in position relative to the engagement arm and the connecting arm. The first engagement arm is coupled to the second engagement arm by one or more biasing arms. The engagement arm is configured to engage the catheter coupler. The catheter coupler is configured to couple to a luer such that when the luer is coupled to or disposed within the catheter coupler, the engagement arm couples to an outer surface of the catheter coupler, thereby securing the catheter coupler to the luer. The engagement arm is configured to prevent inadvertent separation of the catheter coupler from the luer.
[0020] The engagement arm has an engaged position and a disengaged position. In the engaged position, the engagement arm is positioned closer to a central axis of the connector assembly than when the engagement arm is in the disengaged position. In the engaged position, the engagement arm is configured to prevent accidental or unexpected separation of the catheter coupler from the luer when the catheter coupler is connected to the luer. The engagement arm is configured to engage the catheter coupler to prevent accidental axial movement of the catheter coupler relative to the connector. By preventing axial movement of the catheter coupler relative to the connector, the connector can prevent unintended or unexpected disengagement of the catheter coupler from the luer and connector assembly. The engagement arm can be configured to move from the engaged position to the disengaged position to allow separation of the catheter coupler from the luer.
[0021] In the disengaged position, the engagement arm is positioned further from the central axis of the connector assembly than in the engaged position. Having the engagement arm in the disengaged position allows the catheter coupler to be easily separated from the luer. The engagement arm is configured to transition from the engaged position to the disengaged position in response to a withdrawal force exceeding a predetermined threshold force. By allowing the catheter coupler to be separated from the luer in response to a withdrawal force exceeding a predetermined threshold force, the catheter coupler can be easily removed, if necessary, by applying an increased withdrawal force. In some embodiments, if the withdrawal force does not exceed the predetermined threshold force, the catheter coupler remains secured to the luer by the engagement arm.
[0022] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details to provide a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject technology. Similar components are labeled with the same element numbers for ease of understanding. Reference numbers are generally referenced by the same number without a letter suffix, but may have a letter suffix added to indicate separate instances of common elements.
[0023] While the following description relates to connecting medical fittings for the administration of medical fluids using the disclosed couplers, 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 couplers can be used in any application where it is desirable to secure connections between various tubing and fittings.
[0024] The disclosed connector assembly overcomes several challenges found with certain conventional connector assemblies. One challenge with certain conventional connector assemblies is that they can be difficult to separate from a catheter, resulting in the catheter falling out of the patient. Furthermore, during use, certain conventional connector assemblies may be designed to disengage or fall out in response to a relatively low pull-out force. For example, certain conventional connector assemblies may disengage in response to pull-out forces experienced when a patient turns over in bed, when a patient catches the tubing or line on a bed rail, when a patient is transferred to another bed, when a pediatric patient fumbles, and / or when a confused adult patient pulls out their own line. In fact, the 2017 Association for Vascular Access (AVA) Annual Scientific Meeting reported a 10% disengagement rate per 1,000 patients fitted with peripheral IV catheters, translating to approximately 33 million disengagements per year in the United States alone. The use of certain conventional connector assemblies is undesirable because unexpected or unintentional dislodging of the tubing, catheter, or fitting can interrupt the administration of medical fluids.
[0025] It would therefore be advantageous, in accordance with the present disclosure, to provide a connector assembly / coupler as described herein that allows for improved fixation of a fitting or connector. The disclosed connector assembly is constructed as described herein to allow for secure retention of the connector while allowing for intentional separation and removal of the connector assembly as needed.

[0027] 1A-3 , connector assembly 300 includes connector 100, luer 200, and catheter coupler 400. Connector assembly 300 enables the flow of fluid, such as medical fluid, from a fluid source to a patient by removably connecting a section of tubing or line to another section of tubing or line for fluid communication therewith. In the illustrated example, several sections of tubing may be terminated with connectors / couplers, such as connector 100, luer 200, and / or catheter coupler 400. Connector 100, luer 200, and / or catheter coupler 400 may enable connection and / or disconnection of tubing to enable selective fluid communication therebetween.
[0028] As shown, a first section of tubing can be terminated by a catheter coupler 400 to allow the first section of tubing to be connected and / or disconnected from a luer 200. The catheter coupler 400 can be configured to mate with the luer 200. The catheter coupler 400 can be configured to couple with the luer 200 to allow fluid communication between the catheter coupler 400 and the luer 200. In some embodiments, a first section of tubing (e.g., tubing connected to a catheter to be inserted into a patient) is connected to the catheter coupler 400, and the catheter coupler 400 is configured to couple to the luer 200. The luer 200 can be configured to connect to a second section of tubing (e.g., tubing connected to a fluid source). In some embodiments, the luer 200 is connected to a first section of tubing (e.g., tubing connected to a catheter to be inserted into a patient), and the catheter coupler 400 is connected to a second section of tubing (e.g., tubing connected to a fluid source). A catheter coupler 400 that couples to Luer 200 allows a first section of tubing to be in fluid communication with a second section of tubing. In some embodiments, when catheter coupler 400 is coupled to Luer 200, fluid flows from a fluid source through the first section of tubing, through Luer 200 and catheter coupler 400, into the second section of tubing, and through the catheter to the patient.
[0029] 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, allowing 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 the catheter coupler 400 and prevent axial movement of the catheter coupler 400 relative to the luer 200.
[0030] In some embodiments, the catheter connector 400 includes a first end 401 and a second end 403. The first end 401 can be opposite the second end 403. The first end 401 can be configured to receive the luer 200. The first end 401 of the catheter connector 400 can include an opening 402. The opening 402 can be in fluid communication with tubing to allow fluid to pass through the catheter connector 400. In some embodiments, the opening 402 is sized and shaped to receive the luer 200. The catheter connector 400 can include a valve 404 configured to control fluid flow within the catheter connector 400. In some embodiments, the valve 404 is disposed at least partially within the opening 402. The valve 404 may be disposed near the first end 401. In some embodiments, the valve 404 is configured to receive or couple with the luer 200 to allow the catheter connector 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 tubing. The catheter or needle can be inserted into a patient. In some embodiments, the valve 404 extends from a region near the first end 401 to a region near the second end 403.
[0031] In some embodiments, the connector assembly 300 includes a luer 200. The luer 200 can be made of a rigid polymer, such as polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), or any other type of rigid 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 a catheter coupler 400, fluid can flow from the catheter coupler 400, through the opening 204, and into the channel 213. The luer 200 may 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 may 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 luer 200 are in fluid communication. Alternatively, the catheter coupler 400 may 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, through the opening 402 of the catheter coupler 400, and to a patient.
[0032] In some embodiments, the opening 402 of the catheter coupler 400 and / or the opening 204 of the luer 200 include one or more features that allow the opening 402 to mate 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 200 can mate or otherwise engage with the opening 402 of the catheter coupler 400 to allow fluid communication between the catheter coupler 400 and the luer 200, and between the tubing segments connected thereto. As can be appreciated, the catheter coupler 400 and the luer 200 can be coupled and separated to allow fluid communication, as desired. As shown, the opening 204 can include a smooth, otherwise unthreaded, outer portion. In some embodiments, the opening 204 can include an outer portion that includes threads to facilitate coupling with the catheter coupler 400. The catheter coupler 400 can couple with the luer 200 to provide a needleless connection. Advantageously, the catheter connector 400 can be mated with the luer 200 to form a leak-tight, sealed system, allowing for the delivery of a variety of fluids, medications, and / or liquids.
[0033] Luer 200 can be sized and shaped to mate with opening 402 of catheter coupler 400. In some embodiments, when Luer 200 is coupled to catheter coupler 400, a fluid pathway is formed from a fluid source through Luer 200 via opening 204, through opening 402, and through catheter coupler 400 to a catheter connected to a patient. In some embodiments, catheter coupler 400 couples to Luer body 202 of Luer 200. Catheter coupler 400 can couple to Luer body 202 to allow opening 402 to be in fluid communication with Luer pin 210 and channel 213. In some embodiments, Luer pin 210 includes a valve (e.g., valve 214) configured to control fluid flow within Luer 200. For example, valve 214 can be configured to control fluid flow within channel 213 of Luer pin 210.
[0034] 2A-2B , luer 200 can be coupled to housing 500. Housing 500 can be coupled to a section of tubing that can be connected to a fluid source. Housing 500 can be made of a rigid polymer, such as polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), or any other type of rigid polymer. In some embodiments, housing 500 includes a channel 506 in fluid communication with opening 204 and luer pin 210 of luer 200. Channel 506 can be configured to receive a portion of the tubing or to allow fluid communication between a portion of the tubing and luer 200. In some embodiments, housing 500 includes opening 511 configured to receive a portion of luer pin 210. At least a portion of luer pin 210 can be disposed within luer body 202 such that luer body 202 abuts or contacts opening 511 of housing 500. The housing 500 can include a channel 506, which can be in fluid communication with the Luer channel 213.
[0035] In some embodiments, channel 506 receives a portion of luer pin 210, allowing luer 200 to be in fluid communication with a portion of the tubing. In some embodiments, luer pin 210 is disposed within luer body 202 and extends from luer body 202 (e.g., opposite opening 204) such that luer pin 210 extends into channel 506 of housing 500. Luer body 202 may contact, abut, or be positioned adjacent to opening 511 of channel 506. Luer pin 210 may be coupled to or partially disposed within channel 506 such that channel 506 is in fluid communication with luer pin 210. In some embodiments, luer pin 210 is at least partially secured within channel 506 such that axial movement of luer pin 210 relative to housing 500 is prevented.
[0036] In some embodiments, luer body 202 is configured to move axially relative to luer pin 210. Luer pin 210 may be coupled to housing 500 and may be at least partially disposed within luer body 202. In some embodiments, luer pin 210 is fixed to housing 500, and luer body 202 is configured to move axially relative to luer pin 210 and / or housing 500. Luer 200 may include a cavity 217 and may include a biasing element 211 disposed within cavity 217. In some embodiments, at least a portion of luer pin 210 is disposed within cavity 217 of luer body 202. Biasing element 211 may be configured to bias luer body 202 toward housing 500. Biasing element 211 may include one end coupled to housing 500 (e.g., near opening 511) and another end coupled to luer body 202 (e.g., within cavity 217). In some embodiments, when catheter coupler 400 is coupled to luer 200 and pulled axially away from housing 500, biasing element 211 can expand (e.g., lengthen) by causing luer body 202 to move axially away from housing 500 relative to luer pin 210.
[0037] Luer 200 can include a biasing element 211. The biasing element 211 can be disposed within luer body 202. In some embodiments, biasing element 211 is disposed between luer pin 210 and the inner surface of luer body 202. Biasing element 211 can be configured to allow axial movement of luer body 202 relative to luer pin 210. Biasing element 211 can be configured to bias luer body 202 toward housing 500. Luer body 202 can move axially along central axis AA relative to luer pin 210. For example, luer body 202 can move axially relative to luer pin 210 from abutting opening 511 of channel 506 to moving away from opening 511. However, biasing element 211 can also be configured to bias luer body 202 back to abutting opening 511 of channel 506 of housing 500.
[0038] Luer 200 can include one or more protrusions 206. In some embodiments, luer 200 includes two protrusions 206 disposed on luer body 202 of luer 200. Protrusions 206 can be disposed opposite each other. Luer 200 can include one, three, four, or more than four protrusions 206. In some embodiments, protrusions 206 extend perpendicular to central axis AA and away from luer body 202. Protrusions 206 can move axially due to axial movement of luer body 202. For example, luer body 202 can move axially away from housing 500 relative to luer pin 210, which can cause axial movement of protrusions 206 away from housing 500. Protrusions 206 can be generally circular.
[0039] In some embodiments, movement of Luer body 202 relative to Luer pin 210 away from opening 511 results in valve 214 in Luer pin 210 closing, preventing fluid from leaking or spilling from Luer pin 210 into Luer body 202 or out of Luer 200. For example, when Luer body 202 is pulled axially away from housing 500 (e.g., by pulling on catheter coupler 400), valve 214 can occlude Luer pin 210 and prevent fluid from entering or exiting Luer 200.
[0040] In some embodiments, the luer 200 includes a valve (e.g., valve 214) to allow flow 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 separated from the catheter coupler 400. The sealing valve can be moved to an open position (e.g., in fluid communication with the luer pin 210) when the catheter coupler 400 is coupled to the luer 200, thereby allowing flow between the luer 200 and the catheter coupler 400.
[0041] Similarly, the catheter coupler 400 can include a sealing valve (e.g., valve 404) to allow flow 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 from the opening 402 when the catheter coupler 400 is separated from the Luer 200. Furthermore, the sealing valve can be moved to an open position when the Luer 200 is coupled to the catheter coupler 400, thereby allowing flow between the catheter coupler 400 and the Luer 200 (e.g., Luer pin 210). In some embodiments, the sealing valve is formed from silicone.
[0042] In some embodiments, the housing 500 includes a ring 502, a fitted collar 503, and one or more flaps 504. The fitted collar 503 can be disposed between the ring 502 and the flap 504. In some embodiments, the ring 502 is disposed closer to the channel 506 and / or the opening 511 than the flap 504. The ring 502 can have a maximum diameter that is greater than a maximum diameter of the fitted collar 503. The housing 500 can further include a frustoconical or tapered portion 507 and a body 505. The tapered portion 507 can be disposed between the body 505 and the fitted collar 503. The body 505 can extend from the tapered portion 507 and can have a maximum diameter that is smaller than the fitted collar 503. The tapered portion 507 can have a diameter that decreases from a portion near the fitted collar 503 to a portion near the body 505. In some embodiments, flap 504 is disposed in body 505. A portion of luer 200 can be at least partially disposed within body 505 and can extend into channel 506. For example, a portion of luer pin 210 can be disposed within body 505. In some embodiments, housing 500 includes cutouts 508 sized and shaped to receive protrusions 206 of luer 200. Housing 500 can include any number of cutouts 508 corresponding to the number of protrusions 206 of luer 200.
[0043] In some embodiments, the connector 100 includes a base 102 and is coupled to the housing 500 (e.g., via the base 102). A fitted collar 503 may be configured to receive and secure the base 102 of the connector 100. For example, the fitted collar 503 may be sized and shaped such that the base 102 can be disposed around the fitted 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 between a flap 504 and a ring 502 around the fitted collar 503. For example, disposing the base 102 between the ring 502 and the flap 504 may 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 fitted collar 503 by adhesive, a magnet, a hook, or any other type of coupling element.
[0044] In some embodiments, a portion of the lure 200 (e.g., the lure pin 210) and a portion of the connector 100 (e.g., the base 102) are coupled to the housing 500 such that the lure 200 is disposed within the connector 100. For example, a portion of the lure 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 lure 200 (e.g., the lure body 202) extends through the connector 100. The lure pin 210 may be coupled to the housing 500, and the lure body 202 may be configured to move axially relative to the lure pin 210 and the housing 500. In some embodiments, a central axis AA extends longitudinally along the length of the lure 200 and the housing 500 when a portion of the lure 200 is coupled to the housing 500. The connector 100 may be configured to at least partially radially surround the lure 200 and the central axis AA.
[0045] 1A-3 , connector 100 can include a first end 101 and a second end 103. A central axis AA can extend through first end 101 and second end 103. In some embodiments, central axis AA bisects luer 200 and connector 100. Connector 100 can be made of a flexible material and can be of unitary construction. For example, connector 100 can be made of a soft, flexible material such as silicone or rubber. Connector 100 can include a base 102 and can be configured to couple to housing 500 (e.g., via base 102) and extend away from housing 500. In some embodiments, a portion of connector 100 can be configured to move axially along central axis AA away from and / or toward housing 500.
[0046] 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. While FIGS. 1A-3 show the connector 100 having two connecting arms and two engaging arms, the connector 100 may have one, three, four, or more than four connecting 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 place relative to the connecting arms 104, 105. The connecting arms 104, 105 may be configured to contract toward the base 102 and expand away from the base 102. In some embodiments, the connecting arm 104 is coupled to the base 102 on an opposite side from where the connecting arm 105 is coupled to the base 102. The connecting arms 104, 105 can be disposed between the base 102 near the first end 101 and the engaging arms 106, 108. The first connecting arm 104 can be configured to extend from the base 102 and couple to the first engaging arm 106, and the second connecting arm 105 can be configured to extend from the base 102 and couple to the second engaging arm 108. In some embodiments, the first engaging arm 106 extends from the first connecting arm 104 to a region near the second end 103, and the second engaging arm 108 extends from the second connecting arm 106 to a region near the second end 103. In some embodiments, the first engaging arm 106 extends from the first connecting arm 104 to be substantially parallel to the second engaging arm 108 extending from the second connecting arm 105.
[0047] In some embodiments, the first connecting arm 104 and the second connecting arm 105 extend in a spiral configuration from the base 102. For example, the first connecting arm 104 can spiral counterclockwise from the base 102, and the second connecting arm 105 can extend clockwise from the base 102. 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 may allow the engaging arms 106, 108 to move axially along the central axis AA relative to the base 102 and / or the housing 500. For example, the connecting arms 104, 105 may expand away from the base 102 or contract toward the base 102, resulting in movement of the engaging arms 106, 108. The base 102, the connecting arms 104, 105, and the engaging arms 106, 108 may form a unitary structure.
[0048] In some embodiments, the first connection arm 104 connects to the first engagement arm 106 at a connection point 121, and the second connection arm 105 connects to the second engagement arm 108 at a connection point 123. The first connection point 121 may be located on the first engagement arm 106 near the first end 101, and the second connection point 123 may be located on the second engagement arm 108 near the second end 103. The first engagement arm 106 can include a first distal end 110 that can be opposite the first connection point 121. In some embodiments, the first distal end 110 is near the first end 101. The second engagement arm 108 can include a second distal end 112 that can be opposite the second connection point 123. In some embodiments, the second distal end 112 is near the first end 101.
[0049] The connecting arms 104, 105 can be configured to be in a contracted state or an extended state. The connecting arms 104, 105 are biased to be in a contracted position such that they exert a pulling force on the engaging arms 106, 108 when the connecting arms 104, 105 are in the extended position. In the contracted state, the first connecting arm 104 exerts no pulling force on the first engaging arm 106 at connection point 121, and the second connecting arm 105 exerts no pulling force on the second engaging arm 108 at connection point 123. In the extended state, the first connecting arm 104 exerts a pulling force on the first engaging arm 106 at connection point 121, and the second connecting arm 105 exerts a pulling force on the second engaging arm 108 at connection point 123.
[0050] In some embodiments, connector 100 includes one or more biasing arms 115. Biasing arms 115 may be configured to couple first engagement arm 106 to second engagement arm 108. Connector 100 may include two biasing arms 115 positioned opposite one another. However, connector 100 may include any number of biasing arms 115. Biasing arms 115 may be biased to keep first engagement arm 106 substantially parallel to second engagement arm 108 and to keep first engagement arm 106 and second engagement arm 108 close to central axis AA.
[0051] In some embodiments, as the lure body 202 moves axially along the central axis AA away from the housing 500, the protrusion 206 abuts and presses against the biasing arm 115. The pressing of the protrusion 206 against the biasing arm 115 can cause the connecting arms 104, 105 to expand (e.g., stretch) away from the base 102. For example, in response to a pull-out force (e.g., force F) exceeding a predetermined threshold force, the lure body 202 moves axially along the central axis AA away from the housing 500, which can result in the protrusion 206 applying a pressing force to the biasing arm 115. The expansion of the connecting arms 104, 105 can apply a pulling force to the engagement arms 106, 108, 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 pressing 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 pressing against the biasing arm 115 and the connecting arms 104, 105 expanding and pulling the engagement arms 106, 108 toward the base 102.
[0052] 4A is a side perspective view of the connector assembly of FIG. 1A in an engaged position, and FIG. 4B is a side perspective view of the connector assembly of FIG. 2A in a disengaged position.
[0053] 4A-4B, connector 100 can have an engaged position (FIG. 4A) and a disengaged position (FIG. 4B). In the engaged position, first distal end 110 of first engagement arm 106 and second distal end 112 of second engagement arm 108 can be disposed near central axis AA, and first engagement arm 106 can be disposed substantially parallel to second engagement arm 108. When connector 100 is in the engaged position and catheter coupler 400 is coupled to luer body 202, engagement arms 106, 108 can be configured to contact catheter coupler 400 and substantially prevent axial movement of catheter coupler 400 relative to luer body 202 and / or connector 100.
[0054] In some embodiments, the engagement arms 106, 108 include gripping features 119. The gripping features 119 can be configured to secure the catheter coupler 400 to the luer 200 when the catheter coupler 400 is coupled to the luer 200 and the connector 100 is in the engaged position. In some embodiments, the first engagement arm 106 and the second engagement arm 108 each include one or more gripping features 119. The gripping features 119 prevent the catheter coupler 400 from being separated from the luer 200 when the engagement arms 106, 108 are in the engaged position.
[0055] In the engaged position, connector 100 can prevent accidental separation of catheter coupler 400 from luer body 202 by contacting an outer surface of catheter coupler 400 and preventing movement of catheter coupler 400 relative to luer body 202. When connector 100 is in the disengaged position, engagement arms 106, 108 are disposed away from central axis AA and away from luer body 202 such that engagement arms 106, 108 do not contact or abut catheter coupler 400 when catheter coupler 400 is coupled to luer body 202. In the disengaged position, catheter coupler 400 can be easily separated from luer body 202.
[0056] The connector 100 can be configured to transition from the engaged position to the disengaged position in response to a withdrawal force exceeding a predetermined threshold force. For example, a withdrawal force (e.g., force F) can be applied to the catheter coupler 400 when the catheter coupler 400 is coupled to the luer body 202. The catheter coupler 400 is coupled to the luer body 202 such that the withdrawal force can result in axial movement of the luer body 202 relative to the housing 500. In some embodiments, the withdrawal force (e.g., force F) results in axial movement of the luer body 202 relative to the housing 500 only if the withdrawal force exceeds the predetermined threshold force. If the withdrawal force does not exceed the predetermined threshold force, the connector 100 cannot transition from the engaged position to the disengaged position.
[0057] In some embodiments, the connector 100 transitions from an engaged position ( FIG. 4A ) to a disengaged position ( FIG. 4B ) by axial movement of the luer body 202 in response to a withdrawal force (e.g., force F). The connector 100 can transition from the engaged position to the disengaged position 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 luer 200 can be connected to a fluid source via a first tube connected to the housing 500, the luer body 202 (e.g., and luer pin 210) can be connected to the catheter coupler 400, and the catheter coupler 400 can be connected to a patient via a second tube. A force, such as a pull on the catheter coupler 400 and / or tubing connected to the luer 200, can be applied to the first tube. The applied force can be transmitted to the patient if the catheter coupler 400 remains connected to the luer body 202 and the luer 200.
[0058] In some embodiments, separation of the luer body 202 from the catheter coupler 400 prevents the applied force from being transmitted to the patient, preventing accidental harm to the patient (e.g., pulling on a catheter or needle connected to the catheter coupler 400 and inserted into the patient). When a force, such as 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 force F from being applied to the patient or a catheter / needle inserted into the patient.
[0059] 4A illustrates connector 100 in the engaged position in response to force F being equal to or less than a predetermined threshold force applied to luer body 202. For example, connector 100 may be subjected to force from a patient turning over in bed, a patient catching the tubing or line on a bed rail, a patient being transferred to another bed, a pediatric patient fiddling, and / or a confused adult patient pulling out their own line. According to various embodiments of the present disclosure, when subjected to a lower force (e.g., force F is equal to or less than a predetermined threshold force), connector 100 may be configured to be in the engaged position to hold catheter coupler 400 and luer 200 together, so that a fluid pathway remains open and fluid (e.g., IV fluid) may be administered from a fluid source (e.g., a fluid bag, IV bag, fluid container, etc.) through luer 200 to catheter coupler 400 and the patient.
[0060] 4B illustrates the disengaged position of connector 100 when force F exceeds a predetermined threshold force applied to luer body 202. According to various embodiments of the present disclosure, when subjected to a higher force (e.g., force F exceeds the predetermined threshold force), connector 100 may be configured to move to a disengaged position, resulting in the release or otherwise separation of catheter coupler 400 from luer body 202, at which point the fluid path between luer pin 210 and catheter coupler 400 may close and medical fluid (e.g., IV fluid) may be interrupted from entering catheter coupler 400 and / or luer pin 210.
[0061] In some embodiments, the predetermined threshold force may be approximately 5 pounds (lbs). For example, if a patient connected to catheter coupler 400, such as by a needle inserted into the patient's skin, walks away from the fluid source or accidentally pulls on the tubing connected to the fluid source, and the force exceeds 5 lbs, connector 100 may automatically move from an engaged position to a disengaged position, thereby allowing catheter coupler 400 to release or separate from luer body 202, effectively closing the fluid pathway connecting the patient to the fluid source (e.g., via catheter coupler 400 and luer 200). The predetermined threshold force can be between approximately 1 lbs and approximately 10 lbs, between approximately 2 lbs and approximately 8 lbs, between approximately 3 lbs and approximately 6 lbs, or greater than 10 lbs. Having connector 100 release or otherwise separate catheter coupler 400 from luer body 202 is advantageous over conventional couplers that do not release or separate, which can result in bleeding, drug leakage, or other damage.
[0062] In some embodiments, force F exceeding a predetermined threshold force results in axial movement of luer body 202 relative to luer pin 210 and housing 500, which causes axial movement of protrusion 206 along central axis AA. Force F exceeding a predetermined threshold force results in axial movement of luer body 202 relative to luer pin 210, which may close a valve within luer pin 210 and prevent any flow of fluid to or from luer pin 210. Axial movement of protrusion 206 may result in protrusion 206 abutting biasing arm 115 and applying a force (e.g., force F) to biasing arm 115. Axial movement of protrusion 206 relative to biasing arm 115 may also result in connecting arms 104, 105 applying a pulling force to engagement arms 106, 108 at connection points 121, 123, respectively.
[0063] A pulling force pulls biasing arm 115 around protrusion 206, thereby allowing engagement arms 106, 108 to pivot away from lure body 202 and central axis AA. Connecting arms 104, 105 can apply a pulling force to engagement arms 106, 108, respectively, due to their connection to base 102, which is fixed relative to lure body 202. Thus, as lure body 202 moves axially away from base 102, connecting arms 104, 105 transition from a retracted position to an extended position, resulting in a pulling force being applied to engagement arms 106, 108 at connection points 121, 123, respectively. The pulling force applied by connecting arms 104, 105 also results in biasing arm 115 stretching around protrusion 206, which stretches engagement arms 106, 108 to pivot away from lure body 202 and central axis AA. Pivoting of the engaging arms 106, 108 away from the central axis AA results in the connector 100 moving from the engaged position to the disengaged position. The predetermined threshold force can be based on the flexibility or stiffness of the biasing arm 115 and the connecting arms 104, 105. For example, the stiffer the biasing arm 115 and the connecting arms 104, 105, the greater the predetermined threshold force.
[0064] In fact, the catheter coupler 400 can be coupled to the luer 200 with the connecting arms 104, 105 in the retracted position such that the engagement arms 106, 108 are in the engaged position, 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. If a force (e.g., force F) not exceeding a predetermined threshold force is applied to the luer 200, the connector 100 can remain in the engaged position due to the catheter coupler 400 being coupled to the luer body 202. For example, a small force (e.g., a force less than the predetermined threshold force) may be applied to the luer 200 (or a tube coupled to the luer 200). As a result of these small forces, the force applied to the biasing arm 115 by the protrusion 206 is insufficient to transition the connecting arms 104, 105 from the retracted state to the expanded state, preventing the connector 100 from transitioning from the engaged position to the disengaged position. This keeps the catheter connector 400 fixed to the luer body 202 by the engagement arms 106,108.
[0065] When the force F applied to the luer 200 exceeds a predetermined threshold force, the protrusion 206 applies a force to the biasing arm 115, causing the connecting arms 104, 105 to go from a contracted state to an expanded state, thereby pivoting the engaging arms 106, 108 away from the central axis AA, thereby moving the connector 100 from an engaged position to a disengaged position and allowing the catheter coupler 400 to separate from the luer 200. In some embodiments, the biasing arm 115 of the connector 100 is biased against the protrusion 206 by the connecting arms 104, 105 being biased toward the base 102 and the base 102 being fixed relative to the connecting arms 104, 105 and the biasing arm 115.
[0066] 2A , connector 100 can include a shield 150. Shield 150 can extend from first engagement arm 106 to second engagement arm 108. In some embodiments, shield 150 is coupled to biasing arm 115. Shield 150 can cover a portion of luer body 202 and can be configured to provide protection to luer body 202. In some embodiments, shield 150 is comprised of an overmolded elastomer.
[0067] 5A and 5B are perspective and side views of a connector assembly having a mechanical indent according to various embodiments of the present disclosure, respectively.
[0068] 5A-5B , the housing 500 can include an indent 520. The indent 520 can be a ridge, a bevel, or a protrusion disposed in the cutout 508. In some embodiments, the protrusion 206 is disposed within the cutout 508, and the indent 520 is disposed proximal to the cutout 508. The indent 520 can be disposed distal to the ring 502 relative to the protrusion 206 when the protrusion 206 is disposed within the cutout 508. The indent 520 can be configured to increase the force (e.g., force F) required to cause axial movement of the protrusion 206 and, therefore, transition the connector 100 from the engaged position to the disengaged position. In some embodiments, the presence of the indent 520 increases the predetermined threshold force of force F that needs to be exceeded to transition the connector 100 from the engaged position to the disengaged position. The housing 500 can include any number of indents 520. For example, the housing 500 may include a total of one, two, three, four, or more than four indents 520. In some embodiments, the greater the number of indents, the greater the predetermined threshold force of force F required to transition the connector 100 from the engaged position to the disengaged position.
[0069] In some embodiments, the luer 200 includes an anchoring arm 220. The anchoring arm 220 may be configured to aid in coupling the catheter coupler 400 to the luer 200. For example, when the catheter coupler 400 is secured to the luer 200, the anchoring arm 220 may 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 anchoring arm 220 pivots or moves toward the central axis AA, thereby allowing the catheter coupler 400 to separate from the luer 200.
[0070] Figure 6A is a perspective view of a connector assembly having a cover according to various embodiments of the present disclosure. Figure 6B is a front view of the connector assembly of Figure 6A. Figure 6C is a top perspective view of the connector assembly of Figure 6A. Figure 7A is a side view of a connector assembly having a cover disengaged from a catheter coupler according to various embodiments of the present disclosure. Figure 7B is a side view of the connector assembly of Figure 7A engaged with a catheter coupler.
[0071] 6A-7B, connector assembly 100 may include a cover 600. Cover 600 may be configured to surround luer 200 and connector 100. In some embodiments, cover 600 couples to housing 500. In some embodiments, cover 600 couples to ring 502. Alternatively, cover 600 couples to any portion of housing 500. Cover 600 may include a slot 602. Slot 602 may be configured to provide access to luer 200 and connector 100 disposed within cover 600.
[0072] In some embodiments, the catheter coupler 400 is inserted through slot 602 to couple to the luer 200 ( FIG. 7A ). The cover 600 can be waterproof and can prevent contaminants / debris from entering the luer 200, such as through opening 204. In some embodiments, the cover 600 includes a flared portion 604 that is configured to be squeezed (e.g., pushed toward the luer 200) by a user to widen the slot 602 and provide access to the luer 200 ( FIG. 6C ).
