Breakaway connector
A breakaway connector generally includes a first valve having a first rotating-type fluid control member, and a second valve that is attachable to the first valve and has a second rotating-type fluid control member. Each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve. Each one of the valves is configured to engage the fluid control member of the other one of the valves to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.
1. A breakaway connector comprising:
a first valve having a first rotating-type fluid control member; and
a second valve that is attachable to the first valve and has a second rotating-type fluid control member,
wherein each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve, and
wherein the first valve and the second valve are identical, and each one of the first and second valves is configured to engage the fluid control member of the other one of the valves to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.
2. The breakaway connector set forth in claim 1 wherein the engagement is a geared engagement.
3. The breakaway connector set forth in claim 1 wherein each one of the valves is configured for multirotational attachment to the other one of the valves.
4. The breakaway connector set forth in claim 1 wherein each one of the valves are free of ferromagnetic materials.
5. The breakaway connector set forth in claim 1 wherein each one of the valves are configured with attachment indicia for indicating when the valves are completely attached to one another.
6. The breakaway connector set forth in claim 1 wherein each one of the valves comprises a pair of arms that engages the fluid control member of the other one of the valves.
7. The breakaway connector set forth in claim 6 wherein each of the arms of each one of the valves comprises a pair of fingers that defines a receiving space for receiving the fluid control member of the other one of the valves.
8. The breakaway connector set forth in claim 1 wherein each of the valves is configured to restrict the movement of its own fluid control member.
9. The breakaway connector set forth in claim 8 wherein each the valves is configured to frictionally restrict the movement of its own fluid control member.
10. The breakaway connector set forth in claim 1 wherein each one of the fluid control members is a ball-type fluid control member.
11. The breakaway connector set forth in claim 1 wherein each one of the fluid control members is cylindrical.
12. The breakaway connector set forth in claim 1 wherein each one of the valves has a housing, such that each one of the fluid control member and the housing of the each one of the valves deviates from a prism of revolution to facilitate providing an interference fit therebetween that is adjustable to tune a breakaway force of the valves from one another.
13. The breakaway connector set forth in claim 12 further comprising a control structure that is adjustable to tune the breakaway force.
14. The breakaway connector set forth in claim 13 wherein the control structure is a set screw that is adjustable to tune the breakaway force for the valves by modulating a force requirement for rotating the fluid control member of the at least one of the fluid control member and the housing.
15. The breakaway connector set forth in claim 14 wherein the set screw directly contacts the fluid control member of the at least one of the fluid control member and the housing.
16. The breakaway connector set forth in claim 14 wherein the set screw is configured such that adjusting the set screw at least one of compresses and relieves compression of the at least one of the fluid control member and the housing against one another.
17. A kit for administering catheterization treatment, the kit comprising:
a first tube;
a second tube;
a first valve that is connected to the first tube in flow communication, wherein the first valve has a first rotating-type fluid control member; and
a second valve that is connected to the second tube in flow communication and is attachable to the first valve, the second valve having a second rotating-type fluid control member,
wherein each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve, and
wherein each one of the valves is configured to engage the fluid control member of the other one of the valves at two, spaced apart locations to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.
18. The kit set forth in claim 17 wherein each one of the valves comprises a pair of arms, each of the arms comprising a pair of fingers that defines a receiving space for receiving the fluid control member of the other one of the valves.
19. A breakaway connector comprising:
a non-ferromagnetic first valve having a first housing and a first rotating-type fluid control member disposed at least in part within the first housing, wherein the first housing has a pair of arms each having a plurality of gear teeth; and
a non-ferromagnetic second valve that is identical and attachable to the first valve, wherein the second valve has a second housing and a second rotating-type fluid control member disposed at least in part within the second housing, the second housing having a pair of arms each with a plurality of gear teeth,
wherein each of the fluid control members comprises a gear arrangement, and has an open position and a closed position within its respective housing, such that the first pair of arms is configured to engage its gear teeth with the gear arrangement of the second fluid control member to move the second fluid control member from the open position to the closed position upon detachment of the first valve from the second valve, and such that the second pair of arms is configured to engage its gear teeth with the gear arrangement of the first fluid control member to move the first fluid control member from the open position to the closed position upon detachment of the second valve from the first valve.
