Fluid connector assembly
Fluid connector assemblies that seal off fluid paths in the respective connectors are disclosed. When connectors of a fluid connector assembly are connected to each other, respective compressible members in the connectors are displaced, allowing downstream fluid passage through the fluid connector assembly. The fluid connector assemblies may further include a coupling mechanism for providing a connection between the connectors and maintain a connection that provides a threshold retention force. When an external force greater than the threshold force is applied to the fluid connector assembly, the connectors may be decoupled while the coupling mechanism may remain intact.
1. A coupling mechanism for a fluid connector assembly having a first connector and a second connector, the coupling mechanism comprising:
a first member having a first end and a second end opposite the first end; and
a second member comprising:
a first end configured to detachably couple to the second end of the first member; and
a second end opposite the first end, the second end having an opening and one or more ribs and at least one projection configured to flex with respect to another portion of the second member,
wherein the one or more ribs are disposed along a perimeter of the opening and extend inwardly towards a center of the opening for engaging a portion of the fluid connector assembly,
wherein the at least one projection extends inwardly toward the center of the opening of the second member and is configured to couple to a portion of the second connector of the fluid connector assembly, and

3. The coupling mechanism of claim 2 , wherein the first coupling portion and the second coupling portion are threaded.
4. The coupling mechanism of claim 1 , wherein the at least one projection is disposed at a position closer to the second end of the second member than the one or more ribs.
5. The coupling mechanism of claim 1 , wherein the second member is configured to detach from the second connector of the fluid connector assembly upon a separating force exceeding a predetermined threshold.
6. The coupling mechanism of claim 1 , wherein the one or more ribs comprise a first rib disposed along a first side of the perimeter and a second rib disposed along a second side of the perimeter opposite the first side, and wherein each of the first rib and the second rib include a concave portion.
7. A fluid connector assembly comprising:
a first connector;
a second connector for coupling to the first connector; and
a coupling mechanism configured to couple to the first connector, the coupling mechanism having:

a second member having a first end configured to detachably couple to the second end of the first member and a second end opposite the first end and having at least one rib,
wherein, when the coupling mechanism is coupled to the first connector, at least a portion of the first connector is disposed within an interior cavity formed by the coupling mechanism, and
wherein, when the coupling mechanism is coupled to the first connector, the at least one rib contacts an exterior surface of the first connector.
8. The fluid connector assembly of claim 7 , wherein the second member further comprises at least one projection disposed at the second end,
and wherein the at least one projection is configured to contact a portion of the second connector when the coupling mechanism is coupled to the first connector and the first connector is coupled to the second connector.

10. The fluid connector assembly of claim 7 , wherein first member further comprises a first coupling portion and the second member further comprises a second coupling portion, and
wherein, when the first member and the second member are coupled, an exterior surface of the first coupling portion mates with an interior surface of the second coupling portion.
11. The coupling mechanism of claim 10 , wherein the first coupling portion and the second coupling portion are threaded.
12. The coupling mechanism of claim 7 , wherein the second member is configured to detach from the second connector of the the fluid connector assembly upon a separating force exceeding a predetermined threshold.
13. A method for coupling a fluid connecting assembly, the method comprising:
providing a first connector having a first end and a second end opposite the first end and a second connector;
providing a coupling mechanism having:
