Abstract
A syringe apparatus and process is provided for retracting a needle from a hypodermic syringe following the completion of an injection. The hypodermic syringe has a plunger which, upon completion of the injection, is forced downwardly against a needle support deformable base, severing sacrificial supports. An end portion of the needle tears a base portion of the plunger and propels the needle into a hollow region of the plunger such that the needle is contained entirely within the plunger.
