Medical needle assemblies

摘要

A shielded, sterile, single-use unit dose needle assembly includes a unit dose needle with a hub and a packaging shield. The unit dose needle has a handle end and a prong end configured to hold a unit dose of a vaccine. The hub is fixedly attached to the handle end of the unit dose needle and includes a tapered mating surface. The packaging shield includes a tubular housing having an open end and a closed end with an internal opening extending therebetween. The open end of the packaging shield can be removably attached to the tapered mating surface of the hub to form an air-tight seal, with the unit dose needle contained within the internal opening.
