Connector system for releasably connecting fluid conduits
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, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system. Further disclosed herein are embodiments of a connector system for releasably connecting together tubes, whereby the connector system includes at least one valve biased by a valve-biasing member disposed external to or outside of the fluid flow path.
1. A connector system for releasably connecting tubes, comprising:
a female coupler having a first passageway;
a first valve disposed within said female coupler, said first valve operable to interrupt fluid flow through said first passageway;
a male coupler having a second passageway;
a second valve disposed within said male coupler, said second valve operable to interrupt fluid flow through said second passageway;
a catch movably coupled to said female coupler;
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;
wherein in said connected condition, said female coupler urges said second valve toward a second valve open position and said male coupler urges said first valve toward a first valve open position to dispose said first and second passageways in fluidic communication to provide a fluid flow path; and
a release element movably coupled to said female coupler;
wherein travel of said release element along a female coupler outer surface of said female coupler disengages said catch from said catch-receiving element to achieve a disconnected condition of said connector system; and
wherein said travel of said release element along said female coupler outer surface comprises only longitudinal travel along said female coupler outer surface between female coupler first and second ends.
2. The connector system of claim 1 , wherein said travel comprises linear motion along said female coupler outer surface.
3. The connector system of claim 2 , wherein said release element is configured to transform said linear motion along said female coupler outer surface into reciprocating motion of said catch.
4. The connector system of claim 3 , wherein said release element transforms said linear motion along said female coupler outer surface into inward motion of said catch toward an interior of said female coupler or outward motion of said catch away from said interior of said female coupler.
5. The connector system of claim 4 , further comprising a release element-biasing member which biases said release element toward a release element first position in which said release element biases said catch inwardly toward said interior of said female coupler to engage said catch with said catch-receiving element and achieve said connected condition of said connector system.
6. The connector system of claim 5 , wherein said release element-biasing member comprises a resiliently compressible member.
7. The connector system of claim 6 , wherein said resiliently compressible member comprises a spring.
8. The connector system of claim 6 , wherein when in a non-compressed condition, said resiliently compressible member biases said release element toward said release element first position.
9. The connector system of claim 8 , wherein upon forcible urging toward a compressed condition, said resiliently compressible member allows said release element to dispose in a release element second position to allow said catch to outwardly move away from said interior of said female coupler and disengage with said catch-receiving element to achieve said disconnected condition of said connector system.
10. The connector system of claim 1 , wherein said travel of said release element along said female coupler outer surface is achieved by the application of forces directed at an angle of between 0° to about ±45° in relation to said female coupler outer surface.
11. The connector system of claim 1 , wherein said travel comprises sliding travel along said female coupler outer surface.
12. The connector system of claim 11 , wherein said sliding travel is generally parallel to said female coupler outer surface.
13. The connector system of claim 1 , wherein said catch-receiving element is coupled to said male coupler proximate a male coupler matable end which is matably received within a female coupler matable end upon releasable matable axial coupling of said female and male couplers.
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 13 , wherein said catch comprises a ball receivable within said retention groove.
