Description

Technical Field

[0001] The present disclosure relates generally to medical fluid connectors and, more particularly, to fluid connector systems having valve assemblies that can be coupled together to form a fluid pathway. Background Art

[0002] Medical connectors are widely used in fluid delivery systems, such as those used in conjunction with intravenous (IV) fluid lines, blood access, hemodialysis, peritoneal dialysis, enteral feeding, medicine bottle access, and other procedures.

[0003] In some cases, medical connectors may become displaced or disconnected in an unintended manner. For example, medical tubing of an IV kit coupled to a catheter may become displaced when unintended or unexpected forces are applied to the catheter, which may exceed the design limitations of the catheter securing method. Unintended or unintended forces may be applied to the tubing and / or catheter when a patient moves or turns over in bed, or when a catheter or another portion of the IV kit becomes caught on a portion of the bed (such as a railing), or when a patient panics, becomes disoriented, or fidgets to the extent that the medical tubing is accidentally or intentionally pulled away from the patient or from a medical device to which the tubing is coupled.

[0004] In some applications, high pressure medical fluids (up to or exceeding 325 psi) may be used for certain medical infusions. In some applications, when high pressure medical fluids pass through the connector, the medical connection may be disconnected. Utility Model Content

[0005] In accordance with at least some embodiments of the present disclosure, it is recognized that unintended displacement or disconnection of medical connections (such as medical fluid lines) can result in harm to a patient or caregiver, such as by depriving the patient of medications, increasing the likelihood of infection for the patient, and exposing the caregiver to harmful medications.

[0006] Thus, aspects of the present disclosure provide a connector comprising a first connector portion, the first connector portion comprising: a connector housing, the connector housing comprising: a connector body, the connector body defining a housing volume, a Luer opening, and a mating opening, wherein the housing volume is in fluid communication with the Luer opening and the mating opening; and an engagement portion, the engagement portion at least partially surrounding the connector body, the engagement portion defining an engagement lip extending radially toward the connector body, wherein the engagement lip is configured to releasably engage the connector housing with a mating connector portion; and a cover portion, the cover portion being configured to selectively surround the engagement portion of the connector housing, wherein the cover portion is slidable to engage with the engagement portion of the connector housing and prevent release of the connector housing from the mating connector portion.

[0007] In some cases, the present disclosure provides a connector comprising a first connector portion defining a connector volume, a luer opening, and a mating opening, wherein the connector volume is fluidly connected to the luer opening and the mating opening, the first connector portion defining an engagement lip extending radially from the first connector portion, wherein the engagement lip comprises a first lip portion configured to releasably engage an engagement finger of a mating connector portion and a second lip portion configured to prevent release of the engagement finger of the mating connector portion.

[0008] In some cases, the present disclosure provides a connector comprising: a first connector portion, the first connector portion defining a connector volume, a luer opening, and a mating opening, wherein the connector volume is in fluid communication with the luer opening and the mating opening; a second connector portion, the second connector portion comprising a defined second connector volume, a tube opening, and a second mating opening, wherein the second connector volume is in fluid communication with the tube opening and the second mating opening, wherein the first connector portion and the second connector portion are configured to be detachably engaged, and when the first connector portion and the second connector portion are in an engaged state, the mating opening of the first connector portion and the second mating opening of the second connector portion are in fluid communication; and an attachable cover portion, the attachable cover portion selectively surrounds the first connector portion and the second connector portion and prevents release of the first connector portion and the second connector portion.

[0009] Thus, the present application addresses a number of operational challenges encountered in prior art fluid connections and provides a number of improvements that enable users to increase safety and effectiveness while making fluid connections more easily and accurately.

[0037] In the following detailed description, many specific details are set forth in order to provide a full understanding of the subject technology. It should be understood that the subject technology can be practiced without these specific details. In other cases, well-known structures and techniques are not shown in detail to avoid confusing the subject technology.

[0038] Furthermore, although the present specification sets forth specific details of various embodiments, it should be understood that the description is illustrative only and should not be construed as limiting in any way. Furthermore, it is contemplated that although specific embodiments of the present disclosure may be disclosed or illustrated in the context of an IV set, these embodiments may be used in other fluid delivery systems. Furthermore, various applications of such embodiments and modifications thereof that may occur to a person skilled in the art are also included in the general concepts described herein.

[0039] According to some embodiments, the present application discloses various features and advantages of a fluid connector system. The fluid connector system can provide effective and safe maintenance of fluid connections, such as connections for delivering medical fluids to or away from a patient. When pulling or tensioning forces are applied to the fluid connector system, such as when a patient moves or when a medical tube is pulled away from a patient, the fluid connector system can maintain a fluid pathway by preventing unintended disconnection.

[0040] When the pulling force or tension exceeds a threshold value, the fluid connector system can also prevent harm to the patient or caregiver by allowing disconnection or separation between the parts of the connector system. When disconnection or separation occurs between the parts of the connector system, the fluid connector system can also prevent harm to the patient or caregiver by blocking the fluid pathway. In addition, the fluid connector system can provide effective and safe reconstruction of the fluid pathway by allowing the parts of the system to be reassembled after disconnection or separation. Advantageously, the fluid connector described herein can prevent blood loss, IV fluid loss, infection and / or delays in drug delivery. In some applications, the design of the fluid connector can facilitate effective cleaning and disinfection of components.

[0041] Additionally, in some applications, the fluid connector system can selectively resist accidental disconnection during certain events or applications and selectively allow disconnection or separation between parts of the connector system when the pulling or tensioning force exceeds a threshold. For example, the fluid connector system can be configured to resist disconnection or separation during high pressure infusion (fluid pressure up to or exceeding 325 psi) or during other clinical operations that may cause the fluid connector system to accidentally disconnect. When the pulling or tensioning force exceeds a threshold, the fluid connector system can be reconfigured to selectively allow disconnection or separation between parts of the connector system.

[0042] Now referring to the accompanying drawings, Figure 1 An example of a fluid connector 100 in use according to aspects of the present disclosure is shown. The connector system 100 couples with tubing of an IV set for directing fluid to a patient 10. The IV set may include a medication bag 12, a drip chamber 14, tubing 16, and an IV catheter 18.

[0043] The connector system 100 connects the tubing 16 fluid to the IV catheter 18. Although the connector system 100 is shown as being connected between the drug bag 12 and the patient 10 along the fluid pathway of the IV kit, it should be understood that the connector system 100 can be connected in other fluid pathways, such as between the patient and the IV pump or between the patient and the dialysis machine. The connector system 100 can also be connected along another portion of the fluid pathway. For example, the connector system 100 can be connected along the proximal portion of the fluid pathway, such as between the tubing 16 and the drug bag 12 or other fluid treatment device. In another example, any of the first and second portions of the fluid connector 100 can be directly connected to another fluid delivery device, such as a catheter or a drug bag.

[0044] Figure 2 A cross-sectional view of a separated fluid connector 200 is shown according to aspects of the present disclosure. Figure 2 , the fluid connector 200 provides fluid access to the patient while allowing for a selectable "fusible link" or quick disconnect that allows for controlled disconnection of the fluid connector 200 if excessive force is applied and allows for the connection to remain during a high pressure injection or other procedure. As described herein, the fluid connector 200 can allow for controlled disconnection at a predetermined level of force to prevent accidental removal of the catheter from the patient or to prevent accidental disconnection during a high pressure infusion procedure.

[0045] As shown, the fluid connector 200 provides a flow path or fluid passage from one end of the fluid connector 200 to the opposite end of the fluid connector 200. As shown, the fluid connector 200 includes a first connector portion 220 and a second connector portion 210 that couple together to form a fluid passage.

[0046] Figure 3 According to aspects of the present disclosure, Figure 2 200 is a perspective view of the first connector portion 220 of the fluid connector 200. Figure 4A According to aspects of the present disclosure, Figure 3 The connector body 230 of the first connector part. Figure 4B According to aspects of the present disclosure, Figure 3 The cover portion 240 of the first connector portion. Figure 2-4B, the first connector portion 220 allows fluid to flow into and out of the patient or any other part of the IV set. In the depicted example, the first connector portion 220 includes a sliding portion 240 to allow the first connector portion 220 to be connected to a mating tubing or Luer connector. As shown, the mating Luer connector can be connected to a lumen 241. Fluid can enter and exit the fluid connector 200 through the mating Luer connector via the lumen 241 defined in the sliding portion 240.

[0047] In the depicted example, the sliding portion 240 can be coupled to the rest of the first connector portion 220. In some embodiments, the housing end of the sliding portion 240 can be coupled to the luer end of the connector body 230, allowing the lumen 241 of the sliding portion 240 to be in fluid communication with the lumen 231 of the connector body 230, and generally allowing fluid communication between the sliding portion 240 and the connector body 230. As shown, a portion of the lumen 241 of the sliding portion 240 can be disposed within the lumen 231 of the connector body 230. Optionally, the first connector portion 220 can include a seal 262 to maintain isolation between the lumen 231 of the connector body 230 and the lumen 241 of the sliding portion 240. As described herein, the sliding portion 240 can slide relative to the connector body 230. In some embodiments, the seal 262 can maintain a seal or isolation between the lumen 231 and the lumen 241 when the sliding portion 240 moves or slides relative to the connector body 230.

[0048] As shown, the sliding portion 240 is mated, coupled, or otherwise held together with the connector body 230. In some embodiments, one or more retaining fingers 238 extend from the base 236 of the connector body 230 toward the sliding portion 240. The retaining fingers 238 can extend through one or more windows 248 formed in the base 246 of the sliding portion 240 and expand radially outward to retain the sliding portion 240 relative to the connector body 230. During operation, the retaining fingers 238 can limit the sliding or axial travel of the sliding portion 240 relative to the connector body 230. In some applications, the retaining fingers 238 can be compressed radially inward to allow the sliding portion 240 to be removed from the connector body 230.

[0049] In addition, the second connector portion 210 allows fluid to flow into and out of a fluid source or any other portion of an IV set. In the depicted example, the second connector portion 210 can be connected to a fluid source or other portion of an IV set. A tubing or connector can be received in an opening 214 of the connector housing and can be in fluid communication with a lumen 212 of the second connector portion 210.

[0050] During operation, the connector body 230 of the first connector portion 220 and the second connector portion 210 can be coupled together to allow flow between the first connector portion 220 and the second connector portion 210. In the example shown, the lumen 231 of the connector body 230 can define a mating opening that is in fluid communication with the housing volume and the lumen 241 of the sliding portion 240. Similarly, the second connector portion 210 can define a mating opening 217 that is in fluid communication with the housing volume, the lumen 212, and tubing or other IV kit components coupled to the opening 214 of the second connector portion 210. When the first connector portion 220 and the second connector portion 210 are coupled together, fluid can flow between the mating opening 217 of the first connector portion 220 and the second connector portion 210, thereby allowing flow between the first connector portion 220 and the second connector portion 210.

[0051] In the depicted example, the first connector portion 220 and the second connector portion 210 each include a valve member 260, 216, respectively, to control flow through the connector 200. In particular, the valve members 260, 216 allow fluid to flow between the first connector portion 220 and the second connector portion 210 when the first connector portion 220 and the second connector portion 210 are connected, and prevent fluid flow when the first connector portion 220 and the second connector portion 210 are disconnected.

[0052] In the depicted example, the first connector part 220 and the second connector part 210 can be engaged to fix or hold the first connector part 220 and the second connector part 210 together. As shown, the first connector part 220 and the second connector part 210 can be connected together by fixing a part of the first connector part 220 around the second connector part 210. In the illustrated example, the connector body 230 of the first connector part 220 includes or defines one or more engagement fingers 232. As shown, the engagement fingers 232 extend axially away from the base 236 of the connector body 230. Optionally, the engagement fingers 232 can be arranged circumferentially around the lumen 231 of the connector body 230. In certain embodiments, the engagement fingers 232 can each define a ridge or lip 234 extending radially inwardly toward the lumen 231. Similarly, the second connector part 210 defines a groove 218. Optionally, the groove 218 can be arranged circumferentially around the lumen 212 of the second connector part 210. Additionally, the groove 218 can be defined on an outer surface of the second connector portion 210. During operation, the engagement finger 232 of the first connector portion 220 can engage with the groove 218 of the second connector portion 210 to couple the first connector portion 220 and the second connector portion 210. In some embodiments, the lip 234 of the engagement finger 232 can engage with the groove 218 of the second connector portion 210.

[0053] In the illustrated example, the engagement finger 232 and / or lip 234 of the first connector portion 220 engages the groove 218 of the second connector portion 210 to prevent movement of the first connector portion 220 and the second connector portion 210 in a direction away from each other. In some cases of the present disclosure, the engagement of the engagement finger 232 against the groove 218 can define a snap fit or snap coupling between the first connector portion 220 and the second connector portion 210. In some embodiments, the engagement finger 232 can be deflected to facilitate engagement or disengagement of the engagement finger 232 with the groove 218.

[0054] Although the engagement finger 232 is configured to prevent the separation of the first connector part 220 and the second connector part 210, the engagement finger 232 and / or the groove 218 are also configured to allow the separation of the first connector part 220 and the second connector part 210 when the threshold force is exceeded between the first connector part 220 and the second connector part 210. In some embodiments of the present disclosure, the threshold force for separating the first connector part 220 and the second connector part 210 is greater than or equal to about five pounds (22.25 Newtons). When the engagement finger 232 of the first connector part 220 is biased or bent in the direction away from the groove 218, the first connector part 220 and the second connector part 210 may separate. In the example shown, the first connector part 220 and the second connector part 210 can be separated from each other while maintaining the ability to reconnect the first connector part 220 and the second connector part 210. In some embodiments, the resistance or force to assembly and separation between the first connector portion 220 and the second connector portion 210 can be configured such that the force required to assemble the first connector portion 220 and the second connector portion 210 is less than the force required to separate the first connector portion 220 and the second connector portion 210.

[0055] Figure 5A According to aspects of the present disclosure, Figure 2 A perspective view of the first connector portion 220 of the fluid connector 200. Figure 2-Figure 5A , the connector 200 can prevent accidental disconnection of the first connector portion 220 and the second connector portion 210 during certain applications (such as high-pressure fluid infusion). In the example shown, the first connector portion 220 can include a sliding cover 244 to selectively prevent the engagement finger 232 of the first connector portion 220 from disengaging from the groove 218 of the second connector portion 210.

[0056] In the locked position, the sliding cover 244 can be aligned with the engagement finger 232 to prevent the engagement finger 232 from radially or outwardly deflecting, thereby preventing the engagement finger 232 from disengaging from the groove 218 of the second connector portion 210. In some applications, the sliding cover 244 includes one or more protrusions 242 extending radially toward the engagement finger 232 to prevent the engagement finger 232 from moving radially outward.

[0057] During operation, the sliding cover 244 can move or slide away from the engagement finger 232 to allow the engagement finger 232 to deflect radially or outwardly, thereby allowing the first connector part 220 to engage or disengage with the second connector part 210. The clinician can apply an external force to translate or move the sliding cover 244 to a desired position. As shown, the sliding cover 244 can be formed with a sliding portion 240. In some embodiments, the sliding cover 244 is circumferentially arranged around the lumen 241 of the sliding portion 240. In some embodiments, the first connector part 220 may include a biasing member 250 to push the sliding cover 244 to a locked or held position. The biasing member 250 may be a bellows spring. Optionally, the biasing member 250 may be arranged between the base 246 of the sliding cover 244 and the retaining finger 238 of the connector body 230. In some applications, the clinician may apply an external force to overcome the spring force of the biasing member 250 to move the sliding cover 244 to an unlocked position.

[0058] Figure 5B According to aspects of the present disclosure, Figure 2 A perspective view of the first connector portion 220 of the fluid connector 200. Figure 5B , the projections 242 of the sliding cover 244 can define a slot therebetween, which can allow the engagement fingers 232 to deflect radially or outwardly, thereby allowing the first connector portion 220 to be disengaged from the second connector portion 210. During operation, the sliding cover 244 can be rotated to align the projections 242 with the engagement fingers 232, thereby preventing disconnection, or rotated to align the projections 242 with the slots between the engagement fingers 232, thereby allowing disconnection of the first connector portion 220 from the second connector portion 210.

[0059] Figure 6 A cross-sectional view of a fluid connector 300 according to aspects of the present disclosure is shown. Figure 6 , the fluid connector 300 provides fluid access to the patient while allowing for a selectable "fusible link" or quick disconnect that allows for controlled disconnection of the fluid connector 300 if excessive force is applied and allows for the connection to remain connected during a high pressure injection or other procedure. As described herein, the fluid connector 300 can allow for controlled disconnection at a predetermined level of force to prevent accidental removal of the catheter from the patient or to prevent accidental disconnection during a high pressure infusion procedure.

[0060] As shown, the fluid connector 300 provides a flow path or fluid passage from one end of the fluid connector 300 to the opposite end of the fluid connector 300. As shown, the fluid connector 300 includes a first connector portion 330 and a second connector portion 310 that couple together to form a fluid passage.

[0061] In the depicted example, the first connector portion 330 allows fluid to flow into and out of a patient or any other portion of an IV set. In the depicted example, the first connector portion 330 includes an end portion 336 to be connected to a mating tubing or Luer connector. As shown, the mating tubing or Luer connector can be in fluid communication with a lumen 331. Fluid can pass through the fluid connector 300 and out of the fluid connector through a mating Luer connector via the lumen 331 defined in the first connector portion 330.

[0062] In addition, the second connector portion 310 allows fluid to flow into and out of a fluid source or any other portion of an IV set. In the depicted example, the second connector portion 310 can be connected to a fluid source or other portion of an IV set. The tubing 16 or connector can be received in the opening 314 of the connector housing and can be in fluid communication with the lumen 312 of the second connector portion 310.

[0063] In some embodiments, the tube 16 can slide relative to the opening 314 of the connector housing while maintaining fluid communication with the opening 314 and / or the lumen 312. Optionally, the second connector portion 310 can include a seal 315 to maintain isolation between the lumen 312 of the connector housing and the slidable tube 16. In some embodiments, the seal 315 can maintain a seal or isolation between the tube 16 and the lumen 312 when the tube 16 moves or slides relative to the connector housing.

[0064] During operation, the first connector portion 330 and the second connector portion 310 can be coupled together to allow flow between the first connector portion 330 and the second connector portion 310. In the example shown, the lumen 331 of the first connector portion 330 can define a mating opening. Similarly, the second connector portion 310 can define a mating opening 316 that is fluidly connected to the housing volume, the lumen 312, and the tubing 16 or other IV kit components coupled to the opening 314 of the second connector portion 310. When the first connector portion 330 and the second connector portion 310 are coupled together, fluid can flow between the mating opening 316 of the first connector portion 330 and the second connector portion 310, thereby allowing flow between the first connector portion 330 and the second connector portion 310.

[0065] In the depicted example, the first connector portion 330 and the second connector portion 310 can be engaged to fix or hold the first connector portion 330 and the second connector portion 310 together. As shown, the first connector portion 330 and the second connector portion 310 can be connected together by fixing a part of the first connector portion 330 around the second connector portion 310. In the illustrated example, the first connector portion 330 includes or defines one or more engagement fingers 332. As shown, the engagement fingers 332 extend axially away from the first connector portion 330. Optionally, the engagement fingers 332 can be circumferentially arranged around the lumen 331 of the first connector body 330. In some embodiments, the engagement fingers 332 can each define a ridge or lip 334 extending radially inwardly toward the lumen 331. Similarly, the second connector portion 310 defines a groove 318. Optionally, the groove 318 can be circumferentially arranged around the lumen 312 of the second connector portion 310. In addition, the groove 318 can be defined on the outer surface of the second connector portion 310. During operation, the engagement finger 332 of the first connector portion 330 can engage the groove 318 of the second connector portion 310 to couple the first connector portion 330 and the second connector portion 310. In some embodiments, the lip 334 of the engagement finger 332 can engage the groove 318 of the second connector portion 310.

[0066] In the illustrated example, the engagement finger 332 and / or lip 334 of the first connector portion 330 engages with the groove 318 of the second connector portion 310 to prevent movement of the first connector portion 330 and the second connector portion 310 in a direction away from each other. In some cases of the present disclosure, the engagement of the engagement finger 332 against the groove 318 can define a snap fit or snap coupling between the first connector portion 330 and the second connector portion 310. In some embodiments, the engagement finger 332 can be deflected to facilitate engagement or disengagement of the engagement finger 332 with the groove 318.

[0067] Although the engagement finger 332 is configured to prevent the separation of the first connector part 330 and the second connector part 310, the engagement finger 332 and / or the groove 318 are also configured to allow the separation of the first connector part 330 and the second connector part 310 when the threshold force is exceeded between the first connector part 330 and the second connector part 310. In some embodiments of the present disclosure, the threshold force for separating the first connector part 330 and the second connector part 310 is greater than or equal to about five pounds (22.25 Newtons). When the engagement finger 332 of the first connector part 330 is biased or bent in the direction away from the groove 318, the first connector part 330 and the second connector part 310 may separate. In the example shown, the first connector part 330 and the second connector part 310 can be separated from each other while maintaining the ability to reconnect the first connector part 330 and the second connector part 310. In some embodiments, the resistance or force to assembly and separation between the first connector portion 330 and the second connector portion 310 can be configured such that the force required to assemble the first connector portion 330 and the second connector portion 310 is less than the force required to separate the first connector portion 330 and the second connector portion 310.

[0068] In some embodiments, the connector 300 can prevent accidental disconnection of the first connector portion 330 and the second connector portion 310 during certain applications (such as high pressure fluid infusion). In the example shown, the second connector portion 310 can include a sliding portion 340 having a sliding cover 342 to selectively prevent the engagement finger 332 of the first connector portion 330 from disengaging from the groove 318 of the second connector portion 310.

[0069] In the locked position, the sliding cover 342 can be aligned with the engagement fingers 332 to prevent the engagement fingers 332 from deflecting radially or outwardly, thereby preventing the engagement fingers 332 from disengaging from the grooves 318 of the second connector portion 310.

[0070] During operation, the sliding cover 342 can move or slide away from the engagement finger 332 to allow the engagement finger 332 to deflect radially or outwardly, thereby allowing the first connector part 330 to engage or disengage with the second connector part 310. The clinician can apply an external force to translate or move the sliding cover 342 to a desired position. As shown, the sliding cover 342 can be formed with a sliding portion 340. Optionally, the sliding portion 340 can be coupled to the pipe 16 to allow the sliding cover 342 and the pipe 16 to slide together.
