The present invention relates to improvements in conventional protection barrel and cap packagings for hypodermic needles, whereby a structural guard is provided to encourage a user's fingers to locate directly behind the guard, and around the outer surface of an opening into the protected barrel. A person inserting a needle into a barrel automatically seeks to grasp the barrel proximate its open end, to avoid yawing of the barrel during the manipulative process. The present invention facilitates holding of a barrel proximate the opening, while providing, as an extension therefrom, a needle entrance guide means which extends axially and laterally therefrom. The laterally expanded barrel opening defines a transition ramp surface into the barrel open end. Accordingly, the present invention ensures that the needle will be guided into the barrel open end and towards the barrel closed end, even if the needle insertion step included an initial lateral misalignment, off the axial centerline of the barrel cap which extends the guard protections of the barrel needle barrel protector, through a cap which comprises an extending boss from the exterior surface of the cap, so that both needles will be guided away from accidental, manipulative stabbing. A fourth object of the present invention is to provide a protective barrel and extended cap packaging for enclosing a hypodermic needle and syringe assembly, wherein a disposable axially extending housing can be discarded, leaving a protective needle barrel to offer protection to the user, when reinserting only the barrel onto the needle.
