ABSTRACT:
An automatic injector having a needle which is driven out of a body of the injector automatically by drive means also has an associated protective, or sharps, assembly. The sharps assembly has a cover member adapted to cover the needle after the injector has been used. The assembly is operative to provide relative movement between the injection needle and the cover member after injection so that the cover member covers the needle after use. The cover member is preferably actuated automatically so that the user never sees the needle.
