Abstract
Abstract Injection apparatus including a needle formed on one extremity with a point and connected on its opposite end with coupling means for coupling to a syringe or the like. A protective sleeve is telescoped over the one extremity of the needle and has one end of a pusher connected therewith, such pusher projecting rearwardly along the needle shank and being connected on its rear extremity with a finger-grasp handle whereby the sleeve may be telescoped rearwardly on such extremity of the needle, the point inserted through the wall of a patient''s vein and the needle projected down such vein. Thereafter, the handle may be pushed to telescope the sleeve outwardly over the needle point to thereby protect the wall of the vein from puncture by said point.
