Luer activated thread coupler
First Claim
1. A coupler for receiving a threaded male luer fitting in sealed relationship, comprising:
- a housing having an attachment end, a conduit end opposite said attachment end and defining a central passageway for providing fluid communication between the luer fitting and a conduit, said attachment end being provided with threads, having a base forming a recess and configured as an externally threaded nipple;
an arrangement attached to said housing for establishing a sealed connection between a luer tip and said central passageway;
said conduit end being of relatively larger diameter than said attachment end and defining a shoulder at a junction of said attachment end and said conduit end; and
a resilient member disposed on said attachment end adjacent said shoulder being retained upon said housing by at least one of said threads and engagement with said recess, said resilient member exerting an axially directed compressive force upon the male luer fitting as it is threadably engaged upon said attachment end.

Abstract
A coupler for receiving a threaded male luer fitting in sealed relationship includes a housing having an attachment end, a conduit end opposite the attachment end and defining a central passageway for providing fluid communication between the luer fitting and a conduit. An arrangement is attached to the housing for establishing a sealed connection between a luer tip and the central passageway. The conduit end has a relatively larger diameter than the attachment end and defines a shoulder at a junction of the attachment end and the conduit end. A resilient member is disposed on the attachment end adjacent the shoulder for exerting an axially directed compressive force upon the male luer fitting as it is threadably engaged upon the attachment end.

12. A coupler for receiving a threaded male luer fitting in sealed relationship, comprising:
-
a housing having an attachment end being provided with threads, a base forming a recess, and a conduit end opposite said attachment end and defining a central passageway for providing fluid communication between the luer fitting and a conduit;
said attachment end configured as an externally threaded nipple and having a resilient resealable penetrable valve member sealingly secured therein;
said conduit end being of relatively larger diameter than said attachment end and defining a shoulder at a junction of said attachment end and said conduit end;
a resilient member disposed on said attachment end adjacent said shoulder being retained upon said housing by at least one of said threads and engagement with said recess, said member being attached to an outer surface of said housing having said threads, said resilient member creating thread interference between said threads of said attachment end and the male luer fitting. - View Dependent Claims (13, 14, 20, 21, 22)
