Additional features and advantages of the subject technology will be set forth in the description below, and in part will be apparent from the description, or may be learned by practice of the subject technology. The advantages of the subject technology will be realized and attained by the structure particularly pointed out in the written description and embodiments hereof as well as the appended drawings.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the subject technology.
Various features of illustrative embodiments of the inventions are described below with reference to the drawings. The illustrated embodiments are intended to illustrate, but not to limit, the inventions. The drawings contain the following figures:
In the following detailed description, numerous specific details are set forth to provide a full 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 have not been shown in detail so as not to obscure the subject technology.
Further, while the present description sets forth specific details of various embodiments, it will be appreciated that the description is illustrative only and should not be construed in any way as limiting. Additionally, it is contemplated that although particular embodiments of the present disclosure may be disclosed or shown in the context of an IV set, such embodiments can be used in other fluid conveyance systems. Furthermore, various applications of such embodiments and modifications thereto, which may occur to those who are skilled in the art, are also encompassed by the general concepts described herein.
In accordance with some embodiments, the present application discloses various features and advantages of a fluid connector system. The fluid connector system can provide for efficient and safe maintenance of fluid connections, such as the connections used for transferring medical fluids toward or away from a patient. The fluid connector system can maintain a fluid pathway by resisting unintended disconnection when a pulling or tension force is applied to the fluid connector system, such as when a patient moves or when the medical tubing is pulled away from the patient.
The fluid connector system can also prevent injury to a patient or a caregiver by permitting disconnection or separation between portions of the connector system when a pulling or tension force exceeds a threshold. The fluid connector system can also prevent injury to a patient or a caregiver by obstructing the fluid pathway when disconnection or separation between portions of the connector system occurs. Further, the fluid connector system can provide for efficient and safe reestablishment of the fluid pathway, by permitting reassembly of portions of the system after a disconnection or separation occurs. Advantageously, the fluid connectors described herein can prevent blood loss, IV fluid loss, infection, and/or delays in medication delivery. In some applications, the design of the fluid connectors can facilitate effective cleaning and sanitization of the components.
Further, in some applications, the fluid connector system can selectively resist unintended disconnection during certain events or applications, and selectively but allow for disconnection or separation between portions of the connector system when a pulling or tension force exceeds a threshold. For example, a fluid connector system can be configured to resist disconnection or separation during high pressure infusion (fluid pressures up to or in excess of 325 psi) or during other clinical operations that may cause the fluid connector system to unintentionally separate. The fluid connector system may be reconfigured to selectively allow for disconnection or separation between portions of the connector system when a pulling or tension force exceeds a threshold.
Referring now to the figures,
The connector system 100 fluidly connects the tubing 16 to the IV catheter 18. Although the connector system 100 is illustrated being coupled along a fluid pathway of an IV set. between a medicament bag 12 and a patient 10, it should be understood that the connector system 100 can be connected within other fluid pathways, such as between a patient and an IV pump or between a patient and a dialysis machine. The connector system 100 can also be connected along another portion of a fluid pathway. For example, the connector system 100 can be connected along a proximal portion of the fluid pathway, such as being connected between the tubing 16 and the medicament bag 12 or other fluid therapy device. In another example, any of the first and second portions of the fluid connector 100 can be directly coupled to another fluid delivery devices, such as the catheter or a medicament bag.
As illustrated, the fluid connector 200 provides a flow path or fluid pathway from one end of the fluid connector 200 to the opposite end of the fluid connector 200. As illustrated, the fluid connector 200 includes a first connector portion 220 and a second connector portion 210 that are coupled together to form a fluid pathway.
In the depicted example, the sliding portion 240 can be coupled to the other portions of the first connector portion 220. In some embodiments, a housing end of the sliding portion 240 can be coupled to a luer end of a 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 illustrated 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 as the sliding portion 240 moves or slides relative to the connector body 230.

In some embodiments, one or more retaining fingers 238 extend from a 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 radially expand 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.
Further, the second connector portion 210 permits fluid flow to and from a fluid source or any other portion of the IV set. In the depicted example, the second connector portion 210 can be connected to a fluid source or other portion of the IV set. Tubing or a 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.
During operation, the connector body 230 of the first connector portion 220 and the second connector portion 210 can be coupled together to permit flow between the first connector portion 220 and the second connector portion 210. In the depicted example, the lumen 231 of the connector body 230 can define a mating opening in fluid communication with a housing volume and the lumen 241 of the sliding portion 240. Similarly, the second connector portion 210 can define a mating opening 217 in fluid connection with a housing volume, the lumen 212, and the tubing or other IV set component coupled to the opening 214 of the second connector portion 210. As the first connector portion 220 and the second connector portion 210 are coupled together, fluid can flow between the mating opening of the first connector portion 220 and the mating opening 217 of the second connector portion 210, allowing flow between the first connector portion 220 and the second connector portion 210.
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 for fluid to flow between the first connector portion 220 and the second connector 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.
In the depicted example, the first connector portion 220 and the second connector portion 210 can be engaged to secure or retain the first connector portion 220 and the second connector portion 210 together. As illustrated, the first connector portion 220 and the second connector portion 210 can be coupled together by securing a portion of the first connector portion 220 around the second connector portion 210. In the depicted example, the connector body 230 of the first connector portion 220 includes or defines one or more engagement fingers 232. As illustrated, the engagement fingers 232 extends axially away from the base 236 of the connector body 230. Optionally, the engagement fingers 232 can be disposed circumferentially around the lumen 231 of the connector body 230. In some embodiments, the engagement fingers 232 can each define a ridge or lip 234 that extends radially inward toward the lumen 231. Similarly, the second connector portion 210 defines a groove 218. Optionally, the groove 218 can be disposed circumferentially around the lumen 212 of the second connector portion 210. Further the groove 218 can be defined on the outer surface of the second connector portion 210. During operation, the engagement fingers 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 fingers 232 can engage with the groove 218 of the second connector portion 210.
In the depicted example, the engagement fingers 232 and/or the lip 234 of the first connector portion 220 engages the groove 218 of the second connector portion 210 to resist movement of the first connector portion 220 and the second connector portion 210 in a direction away from each other. Engagement of the engagement fingers 232 against the groove 218 can, in some instances of the present disclosure, define a snap fitting or snap joint between the first connector portion 220 and the second connector portion 210. In some embodiments, the engagement fingers 232 can deflect to facilitate engagement or disengagement of the engagement fingers 232 with the groove 218.
Although the engagement fingers 232 are configured to resist separation of the first connector portion 220 and the second connector portion 210, the engagement fingers 232 and/or groove 218 are also configured to permit separation of the first connector portion 220 and the second connector portion 210 when a threshold force exceeded between the first connector portion 220 and the second connector portion 210. In some embodiments of the present disclosure, the threshold force for separating the first connector portion 220 and the second connector portion 210 is greater than or equal to approximately five pounds (22.25 Newtons). Separation of the first connector portion 220 and the second connector portion 210 can occur when the engagement fingers 232 of the first connector portion 220 are biased or flexed in a direction away from the groove 218. In the depicted example, the first connector portion 220 and the second connector portion 210 can separate from each other while maintaining the ability to reconnect the first connector portion 220 and the second connector portion 210 together. 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 so that the force required for assembly of the first connector portion 220 and the second connector portion 210 is less than the force required for separation the first connector portion 220 and the second connector portion 210.
In a locking position, the sliding cover 244 can be aligned with the engagement fingers 232 to prevent the radial or outward deflection of the engagement fingers 232, thereby preventing the disengagement of the engagement fingers 232 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 fingers 232 to prevent the outward radial movement of the engagement fingers 232.
During operation, the sliding cover 244 can be moved or slid away from the engagement fingers 232 to allow the engagement fingers 232 to radially or outwardly deflect, permitting the engagement or disengagement of the first connector portion 220 from the second connector portion 210. A clinician may apply an external force to translate or move the sliding cover 244 to a desired position. As illustrated, the sliding cover 244 can be formed with the sliding portion 240. In some embodiments, the sliding cover 244 is circumferentially disposed around the lumen 241 of the sliding portion 240. In some embodiments, the first connector portion 220 can include a biasing member 250 to urge the sliding cover 244 toward a locked or retained position. The biasing member 250 can be a bellows type spring. Optionally, the biasing member 250 can be disposed between the base 246 of the sliding 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 biasing member 250 to move the sliding cover 244 to an unlocked position.

Engagement of the engagement fingers 532 against the hooked lip portions 518a can, in some instances of the present disclosure, define a snap fitting or snap joint between the first connector portion 530 and the second connector portion 510. In some embodiments, the engagement fingers 532 can deflect to facilitate engagement of the engagement fingers 532 with the hooked lip portions 518a.
In the locking position, the hooked lip portions 518a can engage with the hooked ridge or lip 534 of the engagement fingers 532 to prevent the radial or outward deflection of the engagement fingers 532, thereby preventing the disengagement of the engagement fingers 532 from the hooked lip portions 518a of the second connector portion 510.
Similar to the hooked lip portions 518a, the second connector portion 510 defines one or more ramped lip portions 518b. Optionally, the ramped lip portions 518b can be disposed circumferentially around the lumen 512 of the second connector portion 510. Further the hooked lip portions 518a can be defined on the outer surface of the second connector portion 510. As illustrated, the ramped lip portions 518b can be disposed between the hooked lip portions 518a. During operation, the engagement fingers 532 of the first connector portion 530 can engage with the ramped lip portions 518b of the second connector portion 510 to releasably couple the first connector portion 530 and the second connector portion 510. In some embodiments, the lip 534 of the engagement fingers 532 can engage with the ramped lip portions 518b of the second connector portion 510.
In the depicted example, the engagement fingers 532 and/or the lip 534 of the first connector portion 530 engages the ramped lip portions 518b of the second connector portion 510 to resist movement of the first connector portion 530 and the second connector portion 510 in a direction away from each other. In some embodiments, the engagement fingers 532 can deflect to facilitate engagement and disengagement of the engagement fingers 532 with the ramped lip portions 518b.
Although the engagement fingers 532 are configured to resist separation of the first connector portion 530 and the second connector portion 510, in an unlocked position, the engagement fingers 532 and the ramped lip portions 518b are also configured to permit separation of the first connector portion 530 and the second connector portion 510 when a threshold force exceeded between the first connector portion 530 and the second connector portion 510. In some embodiments of the present disclosure, the threshold force for separating the first connector portion 530 and the second connector portion 510 is greater than or equal to approximately five pounds (22.25 Newtons). Separation of the first connector portion 530 and the second connector portion 510 can occur when the engagement fingers 532 of the first connector portion 530 are biased or flexed in a direction away from the ramped lip portions 518b. As illustrated, the ramp or wedge geometry of the ramped lip portions 518b can facilitate the radial expansion or outward deflection of the engagement fingers 532 to disengage the first connector portion 530 from the second connector portion 510. In the depicted example, the first connector portion 530 and the second connector portion 510 can separate from each other while maintaining the ability to reconnect the first connector portion 530 and the second connector portion 510 together. In some embodiments, the resistance or force to assembly and separation between the first connector portion 530 and the second connector portion 510 can be configured so that the force required for assembly of the first connector portion 530 and the second connector portion 510 is less than the force required for separation the first connector portion 530 and the second connector portion 510.
In the depicted example, the first connector portion 630 can include a threaded cover 640 to selectively prevent the disengagement of the engagement fingers 632 of the first connector portion 630 from the groove 618 of the second connector portion 610. In a locking position, the threaded cover 640 can be aligned with the engagement fingers 632 to prevent the radial or outward deflection of the engagement fingers 632, thereby preventing the disengagement of the engagement fingers 632 from the groove 618 of the second connector portion 610. In some applications, the threaded cover 640 can be secured or positioned in the locked position by engaging or screwing the threads 642 of the threaded cover 640 with threads 611 defined on an outer surface of the second connector portion 610.
During operation, the threaded cover 640 can be moved or slid away from the engagement fingers 632 to allow the engagement fingers 632 to radially or outwardly deflect, permitting the engagement or disengagement of the first connector portion 630 from the second connector portion 610. In some applications, the threaded cover 640 can be unscrewed or otherwise disengaged from the threads 611 defined on the second connector portion 610 to allow the threaded cover 640 to be moved away from the engagement fingers 632. In some embodiments, the threaded cover 640 is circumferentially disposed around the body of the first connector portion 630.
