ABSTRACT:
A syringe having a self-contained, sterile, medication impregnated swab by which to apply an anesthetic and/or antiseptic to a targeted tissue area of a patent prior to the administration of an injection at the target site. The swab is carried by and extended through the major flange of a hollow piston stem. A rotatable end cap is pivotally attached to the piston flange to surround the swab and preserve the sterility thereof. After the cap has been opened, the targeted tissue area swabbed, and an injection administered, an elongated body (the protective sheath which initially surrounds the needle cannula to preserve the sterility thereof and prevent an accidental needle strike) is inserted into and pushed distally through the interior of the hollow piston stem to correspondingly drive the swab therewithin. Accordingly, the swab is conveniently, safely and permanently retained within the hollow piston stem to be discarded with the syringe, after use.
