Abstract: This invention relates to a combination needle shield/needle guard device for a hypodermic syringe with a needle permanently attached to the front end of the syringe barrel. This needle shield/needle guard device is positively locked to the syringe barrel and can perform two functions: first, function as a needle shield which encloses and prevents contamination of a sterile needle and secondly, function as a needle guard which can slide on the surface of the syringe barrel, such that the needle can be uncovered and re-covered from behind the needle point, thereby providing a safety feature in that medical personnel can avoid direct contact with a needle point during the process of uncovering or re-covering the needle. More particularly, an unused sterile hypodermic needle is enclosed within the needle shield/needle guard device which protects the needle from contamination.

Abstract: One step manually activated injection apparatus capable of injecting multiple pre-measured doses of liquid medicaments without visibility of needle. It is composed of cylindrical housing unit with small aperture at bottom and removeable manual plunger unit at the top, and within housing unit there is a syringe unit composed of a piston, ampule with pre-measured liquid medicament, needle covered with sterile sheath and clip apparatus attached onto the ampule. The injection apparatus is placed in ready position by contacting the bottom of housing unit against a skin surface. One forward manual push on manual plunger unit performs two distinct functions. First, the manual plunger unit engages the clip apparatus attached to syringe ampule, permitting forward movement of syringe unit within housing unit, allowing needle to pierce sheath and pass externally through aperture of housing unit without visibility into the skin.
