[0001] The present disclosure generally relates to medical fluid connectors. More specifically, it relates to a fluid connector system having a valve assembly that can be connected to form a fluid path.

[0002] Medical connections are widely used in fluid supply systems related to intravenous (IV) infusion lines, blood access, hemodialysis, peritoneal dialysis, enteral nutrition, drug vial access, and other procedures.

[0003] In some cases, medical connections can accidentally disconnect or be cut. For example, the medical tubing of an infusion set connected to a catheter can disconnect if an unexpected or unintended force is applied to the catheter and that force exceeds the design limits of the catheter fixation method. Unintended or unexpected forces can be applied when a patient moves in bed or turns over, or when the tubing or another part of the infusion set gets caught on part of the bed (e.g., a railing), or when a patient is in a panic, confused, or restless state and unintentionally or intentionally pulls the medical tubing away from themselves or from a medical device connected to the tubing.

[0004] In some applications, high-pressure medical fluids (up to or exceeding 325 psi) can be used for certain medical infusions. In certain applications, when high-pressure medical fluids pass through a connection, the medical connection can be cut.

Summary of the Invention

[0005] At least in some embodiments of the present disclosure, it is recognized that an unintentional disconnection or cutting of a medical connection such as a medical infusion line can cause harm to patients and caregivers, such as interruption of the supply of drugs to the patient, increased risk of infection to the patient, and exposure of caregivers to harmful drugs.

[0014] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject technology. It should be understood that the subject technology may be practiced without some of these specific details. In other instances, well-known structures and techniques are not shown in detail so as not to obscure the subject technology.

[0015] Furthermore, although specific details of various embodiments are described in the present disclosure, it is to be understood that these descriptions are for illustrative purposes only and should not be given any limiting interpretation. Further, even if a particular embodiment of the present disclosure is disclosed or illustrated in the description of an infusion set, it is contemplated that such an embodiment may be used in other fluid conveyance systems. Further, various uses that those skilled in the art may envision for such embodiments and modifications thereof are also subsumed within the general concepts described in the present disclosure.

[0016] In accordance with several embodiments, the present invention discloses various features and advantages of fluid connector systems. Fluid connector systems enable the efficient and safe maintenance of fluid connections, such as connections used to supply or drain intravenous fluids to or from a patient. Fluid connector systems can maintain the fluid path by preventing unintended breakage even when tensile forces or tension are applied to the fluid connector system, such as when the patient moves or when a medical tube is pulled away from the patient.

[0017] Fluid connector systems can also prevent injury to patients or caregivers by allowing breakage or separation between parts of the connector system when tensile force or tension exceeds a threshold. Fluid connector systems can also prevent injury to patients or caregivers by blocking the fluid pathway when breakage or separation between parts of the connector system occurs. Furthermore, fluid connector systems can efficiently and safely re-establish the fluid pathway by allowing the system to be partially reassembled after breakage or separation occurs. As an advantage, the fluid connectors described herein can prevent blood loss, fluid loss, infection, and / or delays in medication administration. In some applications, the design of the fluid connector can facilitate effective cleaning and disinfection of its components.

[0018] Furthermore, in some applications, the fluid connector system may selectively prevent unintended disconnection during specific events or applications, and may selectively allow disconnection or separation between parts of the connector system if tensile force or tension exceeds a threshold. For example, the fluid connector system may be configured to prevent disconnection or separation during high-pressure injection (when the fluid pressure is up to or above 325 psi), or during other clinical uses where the fluid connector system may unintentionally separate. The fluid connector system may be configured to selectively allow disconnection or separation between parts if tensile force or tension exceeds a threshold.

[0019] Referring here to the figures, Figure 1 shows an example of a fluid connector 100 according to an aspect of the present disclosure. The connector system 100 is connected to the tubing of an infusion set used to supply fluid to a patient 10. The infusion set may include a drug bag 12, an infusion chamber 14, tubing 16, and an intravenous catheter 18.

[0020] The connector system 100 fluidly connects the tube 16 to the intravenous catheter 18. While the connector system 100 may be connected along the fluid pathway of an infusion set between the drug bag 12 and the patient 10, as illustrated, it should be understood that the connector system 100 may also be connected within other fluid pathways, such as between the patient and an infusion pump, or between the patient and a dialysis machine. The connector system 100 may also be connected along other parts of a fluid pathway. For example, the connector system 100 may be connected along the proximal part of a fluid pathway, such as between the drug bag 12 and the tube 16, or to another fluid therapy device. In another example, either or both of the first and second parts of the fluid connector 100 may be directly connected to other fluid delivery devices, such as catheters or drug bags.

[0021] Figure 2 shows a perspective view of the fluid connector 200 in a separated state according to an embodiment of the present disclosure. Referring to Figure 2, the fluid connector 200 may provide a fluid pathway to the patient while allowing for a "fuse link" or quick disconnect, enabling controlled disconnection in the event of excessive force, and further maintaining the connection during high-pressure infusion or other procedures. As described in the present disclosure, the fluid connector 200 may enable controlled disconnection at a predetermined level of force to prevent the catheter from being unintentionally removed from the patient or to prevent unintentional disconnection during high-pressure infusion procedures.

[0022] As shown in the figure, the fluid connector 200 provides a flow path or fluid path from one end of the fluid connector 200 to the opposite end of the fluid connector 200. As shown in the figure, the fluid connector 200 includes a first connector portion 220 and a second connector portion 210 that are connected to form a fluid path.

[0023] Figure 3 shows a perspective view of the first connector portion 220 of the fluid connector 200 of Figure 2, according to an aspect of this disclosure. Figure 4A shows the connector body 230 of the first connector portion of Figure 3, according to an aspect of this disclosure. Figure 4B shows the cover portion 240 of the first connector portion of Figure 3, according to an aspect of this disclosure. Referring to Figures 2 through 4B, the first connector portion 220 enables flow to be supplied to and discharged from the patient or any other part of the infusion set. In the illustrated example, the first connector portion 220 includes a slide portion 240 that allows the first connector portion 220 to be connected to a mating tube or Luer connector. As shown, a mating Luer connector can be attached to the lumen 241. Fluid can be supplied to and discharged from the fluid connector 200 through the lumen 241 defined in the slide portion 240 and through the mating Luer connector.

[0024] In the illustrated example, the slide portion 240 may be connected to other parts of the first connector portion 220. In some embodiments, the housing end of the slide portion 240 may be connected to the luer end of the connector body 230, in which case the lumen 241 of the slide portion 240 can be fluidly connected to the lumen 231 of the connector body 230, and generally fluid communication is possible between the slide portion 240 and the connector body 230. As shown in the illustration, a portion of the lumen 241 of the slide portion 240 may be located within the lumen 231 of the connector body 230. Optionally, the first connector portion 220 may include a seal 262 to maintain isolation between the lumen 231 of the connector body 230 and the lumen 241 of the slide portion 240. As described in this disclosure, the slide portion 240 may slide relative to the connector body 230. In some embodiments, even if the sliding portion 240 moves or slides relative to the connector body 230, the seal 262 can maintain a seal or isolation between the lumens 231 and lumens 241.

[0025] As shown in the figure, the slide portion 240 is mated with, connected to, or otherwise held by 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 slide portion 240. The retaining fingers 238 may extend through one or more windows 248 formed in the base 246 of the slide portion 240, and may expand radially outward to retain the slide portion 240 relative to the connector body 230. When operated, the retaining fingers 238 may restrict the sliding or axial movement of the slide portion 240 relative to the connector body 230. In some applications, the retaining fingers 238 may be compressed radially inward to allow the slide portion 240 to be removed from the connector body 230.

[0026] Furthermore, the second connector portion 210 allows fluid flow to and from the fluid source or any other part of the infusion set. In the illustrated example, the second connector portion 210 may be connected to the fluid source or any other part of the infusion set. A tube or connector may be received within the opening 214 of the connector housing and may be in fluid communication with the lumen 212 of the second connector portion 210.

[0027] During operation, the connector body 230 of the first connector portion 220 and the second connector portion 210 may be connected in such a way that fluid flow is permitted between the first connector portion 220 and the second connector portion 210. In the illustrated example, the lumen 231 of the connector body 230 may define a mating opening that fluidly communicates with the housing space and the lumen 241 of the slide portion 240. Similarly, the second connector portion 210 may define a mating opening 217 that fluidly communicates with the housing space, the lumen 212, and a tube or other infusion set component connected to the opening 214 of the second connector portion 210. When the first connector portion 220 and the second connector portion 210 are connected, fluid can flow between the mating opening of the first connector portion 220 and the mating opening 217 of the second connector portion 210, thereby allowing fluid to flow between the first connector portion 220 and the second connector portion 210.

[0028] In the illustrated example, the first connector portion 220 and the second connector portion 210 each include valve members 260 and 216 for controlling the flow of fluid through the connector 200. In particular, the valve members 260 and 216 allow fluid to flow between the first connector portion 220 and the second connector portion 210 when they are connected, and prevent fluid flow when they are disconnected.

[0029] In the illustrated example, the first connector portion 220 and the second connector portion 210 can engage to fix or hold the first connector portion 220 and the second connector portion 210 together. As shown, the first connector portion 220 and the second connector portion 210 can be connected by fixing a portion of the first connector portion 220 around the second connector portion 210. In the illustrated example, the connector body 230 of the first connector portion 220 includes or defines one or more mating fingers 232. As shown, the mating fingers 232 extend axially outward from the base 236 of the connector body 230. Optionally, the mating fingers 232 may be circumferentially arranged around the lumen 231 of the connector body 230. In some embodiments, each mating finger 232 may define a protrusion or lip 234 extending radially toward the lumen 231. Similarly, the second connector portion 210 defines a groove 218. Optionally, the groove 218 may be circumferentially arranged around the lumen 212 of the second connector portion 210. Furthermore, the groove 218 may be defined on the outer surface of the second connector portion 210. When operated, the mating fingers 232 of the first connector portion 220 may engage with the groove 218 of the second connector portion 210 to connect the first connector portion 220 and the second connector portion 210. In some embodiments, the lip 234 of the mating finger 232 may engage with the groove 218 of the second connector portion 210.

[0030] In the illustrated example, the mating fingers 232 and / or lip 234 of the first connector portion 220 engage with the groove 218 of the second connector portion 210, preventing movement of the first connector portion 220 and the second connector portion 210 toward each other. The engagement of the mating fingers 232 with the groove 218 may define a snap mating or snap joining between the first connector portion 220 and the second connector portion 210 in some embodiments of the present disclosure. In some embodiments, the mating fingers 232 may be elastically deformable to facilitate engagement with or disengagement from the groove 218.

[0031] The mating fingers 232 are configured to prevent separation of the first connector portion 220 and the second connector portion 210, but the mating fingers 232 and / or groove 218 are also configured to allow separation of the first connector portion 220 and the second connector portion 210 if the force between them exceeds a threshold. In some embodiments of this disclosure, the threshold force for separating the first connector portion 220 and the second connector portion 210 is approximately 5 pounds (22.25 Newtons) or more. Separation of the first connector portion 220 and the second connector portion 210 may occur when the mating fingers 232 of the first connector portion 220 are biased or elastically deformed away from the groove 218. In the illustrated example, the first connector portion 220 and the second connector portion 210 can be separated while maintaining the ability to reconnect to each other. In some embodiments, the restraints or forces on the assembly and separation of the first connector portion 220 and the second connector portion 210 may 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.

[0032] Figure 5A shows a perspective view of the first connector portion 220 of the fluid connector 200 of Figure 2, in accordance with an aspect of the present disclosure. Referring to Figures 2 through 5A, the connector 200 can prevent unintended disconnection of the first connector portion 220 and the second connector portion 210 in certain applications such as high-pressure fluid injection. In the illustrated example, the first connector portion 220 may include a slide cover 244 for selectively preventing the mating fingers 232 of the first connector portion 220 from disengaging from the groove 218 of the second connector portion 210.

[0033] In the locked position, the slide cover 244 may align with the mating fingers 232 to prevent radial or outward elastic deformation of the mating fingers 232, thereby preventing the mating fingers 232 from disengaging from the groove 218 of the second connector portion 210. In some applications, the slide cover 244 includes one or more projections 242 extending radially toward the mating fingers 232 to prevent radial movement of the mating fingers 232.

[0034] During operation, the slide cover 244 may move or slide away from the mating fingers 232 by allowing the mating fingers 232 to elastically deform radially or outward, and may allow the first connector portion 220 to engage with or disengage from the second connector portion 210. A clinician may move or displace the slide cover 244 to a desired position by applying an external force. As shown, the slide cover 244 may be formed integrally with the slide portion 240. In some embodiments, the slide cover 244 is circumferentially disposed around the lumen 241 of the slide portion 240. In some embodiments, the first connector portion 220 may include a bias member 250 for biasing the slide cover 244 toward a locked or retained position. The bias member 250 may be a bellows spring. Optionally, the bias member 250 may be disposed between the base 246 of the slide cover 244 and the retaining fingers 238 of the connector body 230. In some applications, a clinician may apply an external force to overcome the spring force of the bias member 250 in order to move the slide cover 244 to the unlocked position.

[0035] Figure 5B shows a perspective view of the first connector portion 220 of the fluid connector 200 of Figure 2, according to an aspect of the present disclosure. Referring to Figure 5B, the projections 242 of the slide cover 244 may define a slot between them, which may allow radial or outward elastic deformation of the mating fingers 232, and may allow the first connector portion 220 to detach from the second connector portion 210. During operation, the slide cover 244 may rotate to align the projections 242 with the mating fingers 232, thereby preventing breakage, or it may rotate to align the slot between the projections 242 with the mating fingers 232, thereby allowing the first connector portion 220 to detach from the second connector portion 210.

[0036] Figure 6 shows a cross-sectional view of the fluid connector 300 in accordance with an aspect of the present disclosure. Referring to Figure 6, the fluid connector 300 provides a fluid pathway to the patient and may selectively allow a “fuse link” or quick disconnect, allowing for controlled disconnection of the fluid connector 300 in the event of excessive force, and allowing the connection to be maintained during high-pressure infusion or other procedures. As described in the present disclosure, the fluid connector 300 may allow controlled disconnection at a predetermined level of force to prevent unintentional withdrawal of the catheter from the patient or to prevent unintentional disconnection during high-pressure infusion procedures.

[0037] As shown in the figure, the fluid connector 300 provides a flow path or fluid path from one end of the fluid connector 300 to the other end of the fluid connector 300. As shown in the figure, the fluid connector 300 includes a first connector portion 330 and a second connector portion 310 that are connected to form a fluid path.

[0038] In the illustrated example, the first connector portion 330 allows fluid flow to and from either the patient or a portion of the infusion set. In the illustrated example, the first connector portion 330 includes an end portion 336 that connects to a mating tube or a Luer connector. As shown, the mating tube or Luer connector may be in fluid communication with a lumen 331. Fluid may flow through the lumen 331 defined in the first connector portion 330 to the fluid connector 300 through the mating Luer connector.

[0039] Furthermore, the second connector portion 310 allows fluid flow to and from either the fluid source or the infusion set. In the illustrated example, the second connector portion 310 may be connected to other parts of the fluid source or the infusion set. The tube 16 or connector may be received within the opening 314 of the connector housing and may be in fluid communication with the lumen 312 of the second connector portion 310.

[0040] In some embodiments, the tube 16 may slide against the opening 314 of the connector housing while maintaining fluid communication with the opening 314 and / or lumen 312. Optionally, the second connector portion 310 may 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 may maintain a seal or isolation between the tube 16 and the lumen 312 even as the tube 16 moves or slides against the connector housing.

[0041] During operation, the first connector portion 330 and the second connector portion 310 can be connected to allow fluid flow between them. In the illustrated example, the lumen 331 of the first connector portion 330 may define a mating opening. Similarly, the second connector portion 310 may define a mating opening 316 that is in fluid communication with the housing space, the lumen 312, the tube 16, or the opening 314 of the second connector portion 310 or with other infusion set components. When the first connector portion 330 and the second connector portion 310 are connected, fluid flows between the mating opening of the first connector portion 330 and the mating opening 316 of the second connector portion 310, thereby allowing fluid flow between the first connector portion 330 and the second connector portion 310.

[0042] In the illustrated example, the first connector portion 330 and the second connector portion 310 can engage 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 by fixing a portion 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 mating fingers 332. As shown, the mating fingers 332 extend axially outward from the first connector portion 330. Optionally, the mating fingers 332 may be circumferentially arranged around the lumen 331 of the first connector portion 330. In some embodiments, each mating finger 332 may define a protrusion or lip 334 extending radially toward the lumen 331. Similarly, the second connector portion 310 defines a groove 318. Optionally, the groove 318 may be circumferentially arranged around the lumen 312 of the second connector portion 310. Furthermore, the groove 318 may be defined on the outer surface of the second connector portion 310. When operated, the mating fingers 332 of the first connector portion 330 may engage with the groove 318 of the second connector portion 310 to connect the first connector portion 330 and the second connector portion 310. In some embodiments, the lip 334 of the mating finger 332 may engage with the groove 318 of the second connector portion 310.

[0043] In the illustrated example, the mating fingers 332 and / or lip 334 of the first connector portion 330 engage with the groove 318 of the second connector portion 310 to restrain movement of the first connector portion 330 and the second connector portion 310 toward each other. The engagement of the mating fingers 332 with the groove 318 may define a snap mating or snap joining between the first connector portion 330 and the second connector portion 310 in some embodiments of the present disclosure. In some embodiments, the mating fingers 332 may be elastically deformable to facilitate engagement or disengagement between the mating fingers 332 and the groove 318.

[0044] The mating fingers 332 are configured to prevent separation of the first connector portion 330 and the second connector portion 310, but the mating fingers 332 and / or groove 318 are also configured to allow separation of the first connector portion 330 and the second connector portion 310 if the force between them exceeds a threshold. In some embodiments of this disclosure, the threshold force for separating the first connector portion 330 and the second connector portion 310 is approximately 5 pounds (22.25 Newtons) or more. Separation of the first connector portion 330 and the second connector portion 310 may occur when the mating fingers 332 of the first connector portion 330 are biased or elastically deformed away from the groove 318. In the illustrated example, the first connector portion 330 and the second connector portion 310 can be separated while maintaining the ability to reconnect the first connector portion 330 and the second connector portion 310 to each other. In some embodiments, the restraints or forces on the assembly and separation of the first connector portion 330 and the second connector portion 310 may be set 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.

[0045] In some embodiments, the connector 300 can prevent unintended disconnection of the first connector portion 330 and the second connector portion 310 in certain applications such as high-pressure fluid injection. In the illustrated example, the second connector portion 310 may include a slide portion 340 with a slide cover 342 to selectively prevent the mating fingers 332 of the first connector portion 330 from disengaging from the groove 318 of the second connector portion 310.

[0046] In the locked position, the slide cover 342 can align with the mating fingers 332 to prevent radial or outward elastic deformation of the mating fingers 332, thereby preventing the mating fingers 332 from disengaging from the groove 318 of the second connector portion 310.

[0047] During operation, the slide cover 342 may move or slide away from the mating fingers 332 to allow the mating fingers 332 to elastically deform radially or outward, and may allow the first connector portion 330 to engage with or disengage from the second connector portion 310. A clinician may move or displace the slide cover 342 to a desired position by applying an external force. As shown, the slide cover 342 may be formed integrally with the slide portion 340. Optionally, the slide portion 340 may be connected to the tube 16 to allow the slide cover 342 and the tube 16 to slide integrally. In some applications, the force applied to the tube 16 may be used to move the slide cover 342 to the unlocked position. In some embodiments, the slide cover 342 is circumferentially arranged around the second connector portion 310. In some embodiments, the second connector portion 310 may include a bias member 350 for biasing the slide cover 342 toward the locked or retained position. Optionally, the bias member 350 may be positioned between the base of the slide portion 340 and the base of the second connector portion 310. In some applications, a clinician or patient may (unintentionally) apply an external force to the slide cover 342 and / or tube 16, thereby overcoming the spring force of the bias member 350 and moving the slide cover 342 to the unlocked position.

[0048] Figure 7A shows a cross-sectional view of the fluid connector 400 in a locked configuration according to an aspect of the present disclosure. Figure 7B shows a cross-sectional view of the fluid connector 400 in an unlocked configuration according to an aspect of the present disclosure. Referring to Figures 7A and 7B, the fluid connector 400 includes a locking ring 440. In the illustrated example, the fluid connector 400 may include certain features similar to those of the fluid connector 300. Therefore, similar features may be assigned similar reference numerals.

[0049] As shown in the figure, the fluid connector 400 provides a flow path or fluid path from one end of the fluid connector 400 to the other end of the fluid connector 400. As shown in the figure, the fluid connector 400 includes a first connector portion 430 and a second connector portion 410 that are connected to form a fluid path.

[0050] In the illustrated example, the first connector portion 430 allows fluid flow to and from either the patient or the infusion set. In the illustrated example, the first connector portion 430 includes an end portion 436 that connects to a mating tube or Luer connector. In some applications, the end portion 436 defines a male Luer portion 438. As shown, the mating tube or Luer connector may be in fluid communication with a lumen 431. Fluid may flow through the lumen 431 defined in the first connector portion 430 to the fluid connector 400 through the mating Luer connector.

[0051] Furthermore, the second connector portion 410 allows fluid flow to and from either the fluid source or the infusion set. In the illustrated example, the second connector portion 410 may be connected to other parts of the fluid source or the infusion set. A tube or connector may be received within the opening 414 of the connector housing and may be in fluid communication with the lumen 412 of the second connector portion 410.

[0052] During operation, the first connector portion 430 and the second connector portion 410 can be connected to allow fluid flow between them. In the illustrated example, the lumen 431 of the first connector portion 430 may define a mating opening. Similarly, the second connector portion 410 may define a mating opening 416 that communicates fluid with the housing space, the lumen 412, the tubing, or other infusion set components connected to the opening 414 of the second connector portion 410. When the first connector portion 430 and the second connector portion 410 are connected, fluid can flow between the mating opening of the first connector portion 430 and the mating opening 416 of the second connector portion 410, thereby allowing fluid flow between the first connector portion 430 and the second connector portion 410.

[0053] In the illustrated example, the first connector portion 430 and the second connector portion 410 may each include a valve member for controlling the flow of fluid through the connector 400. In particular, the valve member 460 allows fluid to flow between the first connector portion 430 and the second connector portion 410 when they are connected, and prevents fluid flow when they are disconnected.

[0054] Similar to the features described for connector 300, the first connector portion 430 and the second connector portion 410 can engage to fix or hold the first connector portion 430 and the second connector portion 410 together. As shown in the figure, the first connector portion 430 and the second connector portion 410 can be connected by fixing a portion of the first connector portion 220 around the second connector portion 210. In the illustrated example, the first connector portion 430 includes or defines one or more mating fingers 432 having protrusions or lips 234 as necessary. Similar to connector 300, the second connector portion 410 defines a groove 418. In some embodiments, the mating fingers 432 and / or groove 418 of connector 400 can perform functions similar to those of connector 300.

[0055] Figure 8 shows a perspective view of the locking ring 440 of the fluid connector 400 shown in Figures 7A and 7B, in accordance with an aspect of the present disclosure. Referring to Figures 7A through 8, the connector 400 may utilize the locking ring 440 to prevent unintended disconnection of the first connector portion 430 and the second connector portion 410 in certain applications such as high-pressure fluid injection. In the illustrated example, the second connector portion 410 may include a locking ring 440 that selectively prevents the mating fingers 432 of the first connector portion 430 from disengaging from the groove 418 of the second connector portion 410.

[0056] In the locked position (Figure 7A), the lock ring 440 can align with the mating finger 432 to prevent radial or outward elastic deformation of the mating finger 432, thereby preventing the mating finger 432 from disengaging from the groove 418 of the second connector portion 410.

[0057] During operation, the locking ring 440 may move or slide away from the mating fingers 432 to reach an unlocked position (Figure 7B) as the mating fingers 432 elastically deform radially or outward, allowing the first connector portion 430 to engage with or disengage from the second connector portion 410. A clinician may move or displace the locking ring 440 to a desired position by applying an external force. In some embodiments, the locking ring 440 may include one or more projections 444 to allow a clinician to move or displace the locking ring 440.

[0058] In some embodiments, the locking ring 440 may be circumferentially arranged around the second connector portion 510. As shown in the figure, the locking ring 440 may be slidably connected to the second connector portion 410. In some embodiments, the locking ring 440 may be connected to the outer surface of the second connector portion 410 via one or more snaps 442 extending from the second connector portion 410. The locking ring 440 may be displaced relative to the second connector portion 410 and the snaps 442 via one or more slots 441 defined in the locking ring 440. The slots 441 may define detents in the locked and unlocked positions so that the locking ring 440 is held in either the locked or unlocked position.

[0059] Figure 9 shows a perspective view of the fluid connector 500 in accordance with an aspect of the present disclosure. Referring to Figure 9, the fluid connector 500 provides a fluid pathway to the patient and may selectively allow a “fuse link” or quick disconnect, enabling controlled disconnection of the fluid connector 500 in the event of excessive force and maintaining the connection during high-pressure infusion or other procedures. As described in the present disclosure, the fluid connector 500 may allow controlled disconnection at a predetermined level of force to prevent unintentional withdrawal of the catheter from the patient or to prevent unintentional disconnection during high-pressure infusion procedures. Certain elements of the fluid connector 500 are illustrated, while other elements may be omitted for clarity. In some applications, the fluid connector 500 may include components illustrated in other embodiments described in the present disclosure.

[0060] As shown in the figure, the fluid connector 500 provides a flow path or fluid path from one end of the fluid connector 500 to the other end of the fluid connector 500. As shown in the figure, the fluid connector 500 includes a first connector portion 530 and a second connector portion 510 that are connected to form a fluid path.

[0061] Figure 10 shows a perspective view of the first connector portion 530 according to an aspect of the present disclosure. Figure 11 shows a cross-sectional view of the first connector portion 530 of Figure 10 according to an aspect of the present disclosure. Referring to Figures 9 through 11, the first connector portion 530 allows fluid flow to and from either the patient or a portion of the infusion set. In the illustrated example, the first connector portion 530 includes an end portion 536 that connects to a mating tube or a Luer connector. As shown, the mating tube or Luer connector may be in fluid communication with a lumen 531. Fluid may flow through the lumen 531 defined in the first connector portion 530 to and from the fluid connector 500 through the mating Luer connector.

[0062] Figure 12 shows a perspective view of the second connector portion 510 according to an aspect of the present disclosure. Figure 13 shows a cross-sectional view of the second connector portion 510 of Figure 12 according to an aspect of the present disclosure. Referring to Figures 12 and 13, the second connector portion 510 allows fluid flow to and from either a fluid source or an infusion set. In the illustrated example, the second connector portion 510 may be connected to other parts of the fluid source or an infusion set. A tube or connector may be received within the opening 514 and may be in fluid communication with the lumen 512 of the second connector portion 510.

[0063] During operation, the first connector portion 530 and the second connector portion 510 can be connected to allow fluid flow between them. In the illustrated example, the lumen 531 of the first connector portion 530 may define a mating opening. Similarly, the second connector portion 510 may define a mating opening 516 that communicates fluidly with a housing space, a lumen 512, a tube, or other infusion set components connected to the opening 514 of the second connector portion 510. When the first connector portion 530 and the second connector portion 510 are connected, fluid can flow between the mating opening of the first connector portion 530 and the mating opening 516 of the second connector portion 510, thereby allowing fluid flow between the first connector portion 530 and the second connector portion 510.

[0064] Figure 14A shows a cross-sectional view of the fluid connector 500 in a locking configuration according to an aspect of the present disclosure. Referring to Figure 14A, the connector 500 can prevent unintended disconnection of the first connector portion 530 and the second connector portion 510 under the usage conditions of a specific application, such as high-pressure fluid injection. In the illustrated example, the first connector portion 530 may include mating fingers 532 that engage with and lock with one or more hook-shaped lip portions 518a of the second connector portion 510.

[0065] In the illustrated example, the first connector portion 530 includes or defines one or more mating fingers 532. As shown, the mating fingers 532 extend axially outward from the first connector portion 530. Optionally, the mating fingers 532 may be circumferentially arranged around the lumen 531 of the first connector portion 530. In some embodiments, each mating finger 532 may define a hook-shaped protrusion or lip 534 extending radially toward the lumen 531.

[0066] As shown in the figure, the second connector portion 510 defines one or more hook-shaped lip portions 518a. Optionally, the hook-shaped lip portions 518a may be circumferentially arranged around the lumen 512 of the second connector portion 510. Furthermore, the hook-shaped lip portions 518a may be defined on the outer surface of the second connector portion 510. When operated, the mating fingers 532 of the first connector portion 530 can engage with the hook-shaped lip portions 518a of the second connector portion 510 to connect the first connector portion 530 and the second connector portion 510. In some embodiments, the lip 534 of the mating finger 532 may engage with the hook-shaped lip portions 518a of the second connector portion 510.

[0067] In the illustrated example, the mating fingers 532 and / or lip 534 of the first connector portion 530 engage with the hook-shaped lip portion 518a of the second connector portion 510, preventing movement of the first connector portion 530 and the second connector portion 510 toward each other. In some embodiments of the present disclosure, the engagement of the mating fingers 532 with the hook-shaped lip portion 518a can define a snap-fit ​​or snap-connection between the first connector portion 530 and the second connector portion 510. In some embodiments, the mating fingers 532 can be elastically deformed to facilitate engagement with the hook-shaped lip portion 518a.

[0068] In the locked position, the hook-shaped lip portion 518a can engage with the hook-shaped protrusion or lip 534 of the mating finger 532 to prevent elastic deformation of the mating finger 532 radially or outward, thereby preventing the mating finger 532 from detaching from the hook-shaped lip portion 518a of the second connector portion 510.

[0069] Figure 14B shows a cross-sectional view of the fluid connector 500 in an unlocked configuration according to an aspect of the present disclosure. Referring to Figure 14B, the connector 500 may selectively allow disconnection to prevent damage to the connector and / or injury to the patient or clinician. In the illustrated example, the mating fingers 532 of the first connector portion 530 may engage with the inclined lip portion 518b of the second connector portion 510 in a detachable manner. In some embodiments, the first connector portion 530 may be rotatable so that the mating fingers 532 may engage in a locking manner with the hook-shaped lip portion 518a or in a detachable manner with the inclined lip portion 518b.

[0070] Similar to the hook-shaped lip portion 518a, the second connector portion 510 defines one or more inclined lip portions 518b. Optionally, the inclined lip portions 518b may be circumferentially arranged around the lumen 512 of the second connector portion 510. Furthermore, the hook-shaped lip portion 518a may be defined on the outer surface of the second connector portion 510. As shown in the figure, the inclined lip portions 518b may be arranged between the hook-shaped lip portions 518a. When operated, the mating fingers 532 of the first connector portion 530 engage with the inclined lip portions 518b of the second connector portion 510, thereby detachably connecting the first connector portion 530 and the second connector portion 510. In some embodiments, the lips 534 of the mating fingers 532 may engage with the inclined lip portions 518b of the second connector portion 510.

[0071] In the illustrated example, the mating fingers 532 and / or lip 534 of the first connector portion 530 engage with the inclined lip portion 518b of the second connector portion 510, preventing the first connector portion 530 and the second connector portion 510 from moving away from each other. In some embodiments, the mating fingers 532 can be elastically deformed to facilitate engagement and disengagement with the inclined lip portion 518b.

[0072] The mating fingers 532 are configured to prevent separation of the first connector portion 530 and the second connector portion 510, but in the unlocked position, the mating fingers 532 and the inclined lip portion 518b are also configured to allow separation of the first connector portion 530 and the second connector portion 510 when a threshold force is applied between them. In some embodiments of this disclosure, the threshold force for separating the first connector portion 530 and the second connector portion 510 is about 5 pounds (22.25 Newtons) or more. Separation of the first connector portion 530 and the second connector portion 510 may occur when the mating fingers 532 of the first connector portion 530 are biased or elastically deformed away from the inclined lip portion 518b. As shown in the figure, the inclination or wedge shape of the inclined lip portion 518b may facilitate radial expansion or outward elastic deformation of the mating finger 532 in order for the first connector portion 530 to detach from the second connector portion 510. In the illustrated example, even if the first connector portion 530 and the second connector portion 510 are separated from each other, they may still be able to be reconnected. In some embodiments, the resistance or force required to assemble and separate the first connector portion 530 and the second connector portion 510 may be set such that the force required to assemble the first connector portion 530 and the second connector portion 510 is less than the force required to separate them.

[0073] Figure 15 shows a cross-sectional view of a separated fluid connector 600 according to an aspect of the present disclosure. Referring to Figure 15, the fluid connector 600 may include a threaded cover 640 for preventing unintended disconnection of the first connector portion 630 and the second connector portion 610. In the illustrated example, the fluid connector 600 may include certain features similar to those of the fluid connector 400. Thus, similar features may be referred to using similar reference numerals.

[0074] In the illustrated example, the first connector portion 630 may include a threaded cover 640 for selectively preventing the mating fingers 632 of the first connector portion 630 from disengaging from the groove 618 of the second connector portion 610. In the locked position, the threaded cover 640 aligns with the mating fingers 632 and can prevent radial or outward elastic deformation of the mating fingers 632, thereby preventing the mating fingers 632 from disengaging from the groove 618 of the second connector portion 610. In some applications, the threaded cover 640 may be fixed or positioned in the locked position by engaging or screwing a threaded portion 611 defined on the outer surface of the second connector portion 610 with a threaded portion 642 of the threaded cover 640.

[0075] During operation, the threaded cover 640 may move or slide away from the mating fingers 632 to allow the mating fingers 632 to elastically deform radially or outward, and may allow the first connector portion 630 to engage with or disengage from the second connector portion 610. In some applications, the threaded cover 640 may be unscrewed or otherwise disengaged from a threaded portion 611 defined on the second connector portion 610, thereby allowing the threaded cover 640 to move away from the mating fingers 632. In some embodiments, the threaded cover 640 is circumferentially arranged around the body of the first connector portion 630.

[0076] Figure 16 shows a perspective view of a fluid connector 700 with a cover 740 according to an aspect of the present disclosure. Referring to Figure 16, the fluid connector 700 provides a fluid pathway to the patient and includes a removable cover 740 which may selectively allow a “fuse link” or quick disconnect, thus enabling controlled disconnection of the fluid connector 700 in the event of excessive force and allowing the use of a removable lockout or cover 740 to maintain the connection during high-pressure infusion or other procedures.

[0077] As shown in the illustration, the fluid connector 700 provides a flow path or fluid route from one end of the fluid connector 700 to the other end. As shown in the illustration, the fluid connector 700 includes a first connector portion 730 and a second connector portion 710 that are connected to form a fluid route. In the illustrated example, the first connector portion 730 allows fluid flow to and from either the patient or a portion of the infusion set. In the illustrated example, the first connector portion 730 may be connected to a mating tube 16 or a Luer connector. Furthermore, the second connector portion 710 allows fluid flow to and from either the fluid source or a portion of the infusion set. In the illustrated example, the second connector portion 710 may be connected to another portion of the fluid source or infusion set. The tube 16 or connector may be received within the second connector portion 710 and may be in fluid communication with the second connector portion 710.

[0078] During operation, the first connector portion 730 and the second connector portion 710 may be connected to allow fluid flow between them. In the illustrated example, the first connector portion 730 and the second connector portion 710 may be engaged to securely fix or hold the first connector portion 730 and the second connector portion 710.

[0079] The connector 700 is configured to suppress the separation of the first connector portion 730 and the second connector portion 710, but is also configured to allow the separation of the first connector portion 730 and the second connector portion 710 when a threshold force is applied between them.

[0080] In the illustrated example, the connector 700 may include a removable cover 740 for selectively preventing the first connector portion 730 from detaching from the second connector portion 710. In the mounted or locked position, the removable cover 740 may engage with the outer ends or edges of the first connector portion 730 and the second connector portion 710, preventing them from separating or detaching. As shown, the arm 742 may extend from the cover 740 to engage with the ends of the first connector portion 730 and the second connector portion 710, while allowing the tube 16 to pass through the cover 740. Furthermore, the body of the cover 740 may support the first connector portion 730 and the second connector portion 710 to maintain an axially aligned state. In some embodiments, the cover 740 may have an interfering fit or “snap fit” with the connector 700 assembled such that the position of the cover 740 is maintained relative to the first connector portion 730 and the second connector portion 710.

[0081] During operation, the cover 740 may be removed, thereby allowing the first connector portion 730 to detach from the second connector portion 710. A clinician may remove the cover 740 from the first connector portion 730 and the second connector portion 710 by applying a removal force to the handle portion 746 of the cover 740.

[0082] Figure 17 shows a perspective view of a fluid connector 800 with a cover 840 according to an aspect of the present disclosure. Figure 18 shows a cross-sectional view of a fluid connector 800 with a cover 840 according to an aspect of the present disclosure.

Referring to Figures 17 to 19A, the fluid connector 800 may include a hinged cover 840 to prevent unintended disconnection of the first connector portion 830 and the second connector portion 810. In the illustrated example, the fluid connector 800 may include certain features similar to those of the fluid connector 700. Thus, similar features may be referred to using similar reference numerals.

[0083] In the illustrated example, the connector 800 may include a removable cover 840 for selectively preventing the first connector portion 830 from detaching from the second connector portion 810. In the mounted or locked position, the removable cover 840 may engage with the outer surfaces of the first connector portion 830 and the second connector portion 810 to prevent them from separating or detaching. Furthermore, the cover body 842 may support the first connector portion 830 and the second connector portion 810 to maintain an axially aligned state. As shown in the illustration, the cover body 842 is formed as an outer frame surrounding the outer surfaces and / or edges of the first connector portion 830 and the second connector portion 810, while allowing a clinician to monitor the fluid flow through the first connector portion 830 and the second connector portion 810. The cover body 842 may include openings to allow the tube to pass through the cover 840 while the cover 840 engages with the ends of the first connector portion 830 and the second connector portion 810. In some embodiments, the cover 840 may have an interlocking or "snap-fit" with the assembled connector 800 so that the position of the cover 840 is maintained relative to the first connector portion 830 and the second connector portion 810.

[0084] Figure 19B shows a perspective view of a cover 840 for a fluid connector 800 in an open position, according to an aspect of the present disclosure.
