Medical needle assemblies

摘要

A shielded, sterile, single-use unit dose needle assembly (10) includes a unit dose needle (12) with a hub (22) and a packaging shield (40). The unit dose needle (12) has a handle end (14) and a prong end (16) configured to hold a unit dose of vaccine. The hub (22) is fixedly attached to the handle end (14) of the unit dose needle (12) and includes a tapered mating surface (32). The packaging shield (40) includes a tubular housing (42) having an open end (44) and a closed end (46) with an internal opening (48) extending therebetween. The open end (44) of the packaging shield (40) can be removably attached to the tapered mating surface (32) of the hub (22) to form an air-tight seal, with the unit dose needle (12) contained within the internal opening (48). <IMAGE>
