Abstract
An adapter is placed between the needle and a conventional fluid store, or medical line. The end of the adapter that connects to the needle assembly is formed to have a configuration that is complementary to that of the hub of the needle assembly, so that the adapter and the needle hub may be readily mated to each other. The other end of the adapter is formed to have another configuration, for example a conventional luer, that is readily connectable to a conventional fluid store, such as a syringe that has a conventional luer. The adapter is formed by inter-fitting two elements to effect an integral locking mechanism to prevent the uncoupling of the fluid store and the adapter, once they are securely coupled.

21. A connector for connecting a fluid store, comprising:
-
a shroud having at least one stop; a core movably fitted to the shroud, the core having a receptacle end matable with a connector end of the fluid store, the core including at least one end stop; wherein the receptacle end of the core and the connector end of the fluid store have complementary configurations that allow those ends to mate to each other when the shroud and the fluid store are rotated relative to each other in a first direction, the rotation of the shroud in the first direction causes the one stop of the shroud and the end stop of the core to bias against each other so that the receptacle end of the core moves in unison with the shroud to mate with the connector end of the fluid store; and wherein once the fluid store is coupled to the connector, the stop of the shroud and the end stop of the core would not bias against each other when the shroud and the fluid store are rotated relative to each other in a second direction opposite to the first direction so that the rotation of the shroud is independent of the movement of the core. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A connector for establishing a fluid path between a fluid store and a receptacle end wherefrom a fluid from the fluid store may be conveyed to a patient, comprising:
-
a shroud having at least one stop; a core movably fitted to the shroud, the core having a first end matable with a receptacle end and a second end matable with a connector end of the fluid store, the core including at least one end stop; wherein the receptacle end of the core and the connector end of the fluid store are matable to each other when the shroud and the fluid store are rotated relative to each other in a first direction, the rotation of the shroud in the first direction causes the one stop of the shroud and the end stop of the core to bias against each other so that the receptacle end of the core moves in unison with the shroud to mate with the connector end of the fluid store; and wherein once the fluid store is coupled to the connector, the stop of the shroud and the end stop of the core would not bias against each other when the shroud and the fluid store are rotated relative to each other in a second direction opposite to the first direction so that the rotation of the shroud is independent of the movement of the core. - View Dependent Claims (32, 33, 34, 35)

36. A method of manufacturing a connector comprising the steps of:
-
providing a shroud having at least one stop; providing a core having a receptacle end matable with a connector end of a fluid store, the core including at least one end stop; fitting the core to the shroud so that the core and the shroud are rotatable relative to each other if the one stop and the end stop do not bias against each other; configuring the receptacle end of the core to have a configuration complementary to the configuration of the connector end of the fluid store so that the receptacle end and the connector end are mated to each other when the shroud and the fluid store are rotated relative to each other in a first direction, the rotation of the shroud in the first direction causes the one stop of the shroud and the end stop of the core to bias against each other so that the receptacle end of the core moves in unison with the shroud to mate with the connector end of the fluid store. - View Dependent Claims (37, 38, 39, 40)
