Abstract

Disclosed herein are embodiments of a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway; a male coupler having a second passageway; and a catch assembly comprising a catch movably coupled to the female coupler, a catch-biasing member which biases the catch, and a follower responsive to a cam, whereby the catch is responsive to the follower and correspondingly, the cam.

Claims (58)

1. A connector system for releasably connecting tubes, comprising:

a female coupler having a first passageway;

a male coupler having a second passageway; and

a catch assembly comprising:

a catch movably coupled to said female coupler;

a catch-biasing member comprising a pair of resiliently flexible arms which outwardly extend from said catch; and

a follower responsive to a cam;

said catch responsive to said follower and correspondingly, said cam; and

said catch assembly comprising a one-piece construct.

2. The connector system of claim 1 , wherein said catch, said catch-biasing member, and said follower are formed as said one-piece construct.

3. The connector system of claim 1 , wherein catch assembly comprises an annular member.

4. The connector system of claim 3 , wherein said annular member comprises a first portion which provides said catch and an opposing second portion which provides said follower.

5. The connector system of claim 4 , wherein said catch-biasing member outwardly extends from said first portion of said annular member which provides said catch.

6. The connector system of claim 1 , wherein said catch assembly comprises a monolithic construct.

7. The connector system of claim 1 , said pair of resiliently flexible arms outwardly extending from said catch in opposing directions.

8. The connector system of claim 1 , said catch-biasing member disposed opposite said follower.

9. The connector system of claim 1 , further comprising a catch-receiving element coupled to said male coupler;

wherein upon releasable matable axial coupling of said female and male couplers, said catch engages with said catch-receiving element to fix an axial position of said female coupler in relation to said male coupler, thereby achieving a connected condition of said connector system in which said first and second passageways dispose in fluidic communication to provide a fluid flow path.

10. A connector system for releasably connecting tubes, comprising:

a female coupler having a first passageway;

a male coupler having a second passageway; and

a catch assembly comprising:

a catch movably coupled to said female coupler;

a catch-biasing member comprising a pair of resiliently flexible arms which outwardly extend from said catch; and

a follower responsive to a cam;

said catch responsive to said follower and correspondingly, said cam; and,

said catch movably coupled to said female coupler such that said catch is capable of:

inward movement toward a female coupler inner space defined by a female coupler inner surface of said female coupler; and

outward movement away from said female coupler inner space.

11. The connector system of claim 10 , wherein said catch is movably coupled to said female coupler inner surface.

12. The connector system of claim 11 , wherein said catch is movably disposed within a channel inset within said female coupler inner surface; and

wherein said channel communicates with said female couple inner space.

13. The connector system of claim 12 , further comprising a catch-receiving element coupled to said male coupler;

wherein upon releasable matable axial coupling of said female and male couplers, said catch engages with said catch-receiving element to fix an axial position of said female coupler in relation to said male coupler, thereby achieving a connected condition of said connector system in which said first and second passageways dispose in fluidic communication to provide a fluid flow path.

14. The connector system of claim 13 , wherein said catch-receiving element comprises a retention groove disposed within a male coupler outer surface proximate said male coupler matable end.

15. The connector system of claim 14 , wherein upon releasable matable axial coupling of said female and male couplers, said retention groove aligns with said channel to allow said catch to move outwardly from said channel and inwardly toward said female coupler inner space for engagement with said retention groove to dispose said catch in an engaged condition to fix said axial position of said female coupler in relation to said male coupler.

16. The connector system of claim 15 , wherein said catch is movably coupled to said female coupler such that said catch is capable of movement within in a plane which is generally orthogonal to a longitudinal axis of said female coupler.

17. The connector system of claim 16 , wherein upon releasable matable axial coupling of said female and male couplers, said retention groove, said channel, and said catch align in said plane to allow said catch to move outwardly from said channel and upwardly in said plane for engagement with said retention groove to dispose said catch in said engaged condition to fix said axial position of said female coupler in relation to said male coupler.

18. The connector system of claim 17 , wherein said catch-biasing member normally biases said catch inwardly toward said female coupler inner space or upwardly in said plane.

19. A connector system for releasable connecting tubes, comprising:

a female coupler having a first passageway;

a male coupler having a second passageway; and

a catch assembly comprising:

a catch movably coupled to said female coupler;

a catch-biasing member comprising a pair of resiliently flexible arms which outwardly extend from said catch; and

a follower responsive to a cam;

said catch responsive to said follower and correspondingly, said cam; and

said cam provided by a release element which is movably coupled to said female coupler.

20. A connector system for releasably connecting tubes, comprising:

a female coupler having a first passageway;

a male coupler having a second passageway;

a catch assembly comprising:

a catch movably coupled to said female coupler;

a catch-biasing member comprising a pair of resiliently flexible arms which outwardly extend from said catch; and

a follower responsive to a cam;

said catch responsive to said follower and correspondingly, said cam;

a first valve disposed within said female coupler, said first valve operable to interrupt fluid flow through said first passageway; and

a second valve disposed within said male coupler, said second valve operable to interrupt fluid flow through said second passageway.
