Abstract

A method and apparatus for an improved luer fitting connector is disclosed.
The luer fitting connector includes a male or female luer fitting member and a locking member. The locking member may have at least one of a skeletal handle, a finlike handle, a cavity grip, and an undulating grip. The luer fitting connector also may include a male or female luer fitting member having a conical restraining surface and a locking member having a plateau shaped protrusion. A method of assembly of luer fitting connector members is also disclosed. The method may include providing a male or female luer fitting member having a conical restraining surface and providing a locking member having a plateau shaped protrusion. The method also may include mounting the locking member upon the male or female luer fitting member from the rear.

Claims (20)

1. A luer fitting connector assembly operable to interconnect a male luer fitting member and a female luer fitting member, the luer fitting connector assembly comprising:
one of the male or female luer fitting members; and a locking member mounted upon said one of the male or female luer fitting members, the locking member comprising a cavity grip having an indentation approximating the shape of a human thumbprint.
2. The luer fitting connector assembly of claim 1, wherein the locking member comprises a finlike handle.
3. The luer fitting connector assembly of claim 1, wherein the locking member comprises an undulating grip.
4. The luer fitting connector assembly of claim 1, wherein the locking member comprises a skeletal handle.
5. A luer fitting connector assembly operable to interconnect a male luer fitting member and a female luer fitting member, the luer fitting connector assembly comprising:
one of the male or female luer fitting members; and a locking member mounted upon said one of the male or female luer fitting members, the locking member comprising at least one of a skeletal handle, an undulating grip, and a finlike handle, wherein the finlike handle extends a majority of the longitudinal length of the locking member.
6. The luer fitting connector assembly of claim 5, wherein the locking member comprises a cavity grip having an indentation approximating the shape of a human thumbprint.
7. The luer fitting connector assembly of claim 5, wherein the finlike handle radially extends outward from approximately one longitudinal end of the locking member.
8. The luer fitting connector assembly of claim 5, wherein the undulating grip comprises ten waves.
9. The luer fitting connector assembly of claim 5, wherein the locking member comprises both a skeletal handle and an undulating grip.
10. The luer fitting connector assembly of claim 5, wherein the locking member comprises both a finlike handle and an undulating grip.
