Abstract: The needle head assembly is used with an ISO luer lock or luer slip syringe having a single thread or multiple threads. The assembly includes a one or two piece luer needle housing having a plunger end, a needle end and a pair of opposing slots located at the needle end thereof. A plunger is axially movable relative to the upper end of the luer needle housing. A needle holder assembly is located in the needle end of the needle housing, with the holder assembly including a bridge fixed in the needle end of the needle housing. The bridge includes a needle holder that has portions extending in opposite directions from the bridge. A diaphragm with a center aperture is sleeved over one of the portions of said needle holder which faces the plunger end of the needle housing. The needle holder has a center passage which permits a needle to be inserted and secured in position at the time of assembly.

Abstract: The needle protection holder encloses an automatically retractable safety syringe and needle within a tubular cylinder after the needle has been used. Its intended purpose is to remove a needle attached to a syringe from a patient, both human and animal, thereby containing the needle safely within the holder or cylinder. With such a construction, the holder prevents the exchange of bodily fluids caused by needle sticks which are known to cause serious illnesses including death to medical technicians and personnel.

Abstract: The needle protection holder is a device that encloses a syringe and needle within a tubular shell or cylinder after the needle has been used. Its intended purpose is to remove a needle attached to a syringe from a patient, both human and animal, thereby containing the needle safely within the cylinder. The device disallows the exchange of bodily fluids caused by needle sticks which are known to cause serious illness including death in medical technicians.
