SAFETY NEEDLE ASSEMBLY WITH CORRECT MEDICATION CONNECTION
First Claim
1. A needle hub comprising a one piece elongate cylindrical portion with an open end having an opening defined by a circumferential wall and a closed end, the open end forming a hub receptacle end having a particular formation that prevents the hub receptacle end from mating with a conventional luer end of a medical device, said particular formation including two protrusions formed at opposite sides of the hub receptacle end at a particular distance from the opening of the open end so that the protrusions are threadedly matable with an internal thread formed at an inner circumferential wall of a shroud having a complementary configuration to said particular formation, the hub receptacle end with the protrusions not matable with an internally threaded conventional luer end, said particular formation further including the circumferential wall of the elongate cylindrical portion being dimensioned to provide a given cross section for the opening at the hub receptacle end that prevents a conventional male receptacle end from being fittingly accepted into the opening.

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.

- 1. A needle hub comprising a one piece elongate cylindrical portion with an open end having an opening defined by a circumferential wall and a closed end, the open end forming a hub receptacle end having a particular formation that prevents the hub receptacle end from mating with a conventional luer end of a medical device, said particular formation including two protrusions formed at opposite sides of the hub receptacle end at a particular distance from the opening of the open end so that the protrusions are threadedly matable with an internal thread formed at an inner circumferential wall of a shroud having a complementary configuration to said particular formation, the hub receptacle end with the protrusions not matable with an internally threaded conventional luer end, said particular formation further including the circumferential wall of the elongate cylindrical portion being dimensioned to provide a given cross section for the opening at the hub receptacle end that prevents a conventional male receptacle end from being fittingly accepted into the opening.
- 8. A one piece needle hub comprising with an open end having an opening defined by a circumferential wall and a closed end having a needle extending therefrom, the open end forming a hub receptacle end having a particular formation that prevents the hub receptacle end from mating with a conventional luer end of a medical device, said particular formation including two protrusions formed at opposite sides of the hub receptacle end at a particular distance from the opening of the open end so that the protrusions are threadedly matable with an internal thread formed at an inner circumferential wall of a shroud having a complementary configuration to said particular formation, the hub receptacle end with the protrusions not matable with an internally threaded conventional luer end, said particular formation further including the circumferential wall of the hub receptacle end defining the opening to have a dimension that prevents the opening at the hub receptacle end from fittingly accepting a conventional male receptacle end.

14. A system comprising:
-
a one piece needle hub with an open end having an opening defined by a circumferential wall and a closed end having a needle extending therefrom, the open end forming a hub receptacle end having a particular formation that prevents the hub receptacle end from mating with a conventional luer end of a medical device, said particular formation including two protrusions formed at opposite sides of the hub receptacle end at a particular distance from the opening at the open end and the opening of the hub receptacle end dimensioned to have a cross section that prevents the opening from fittingly accepting a conventional male receptacle end; and a fluid store adapted to have a non-removable connector end having a complementary configuration to said particular formation, the connector end including a shroud that has an internal thread formed at its inner circumferential wall that is threadedly matable with the protrusions at the hub receptacle end, the complementary configuration of the connector end preventing the connector end from being connected to a conventional receptacle end of a conventional needle hub. - View Dependent Claims (15, 16, 17, 18, 19, 20)
