Abstract
A device and method for protecting users of hypodermic needle and syringe assemblies from accidental needle-stick injuries in the handling of such assemblies following use thereof and for facilitating the safe disposal of such assemblies. The device comprises a pad of relatively soft sheet material, preferably a sheet of closed-cell plastic foam, having an upper surface coated with a pressure-sensitive adhesive. A shield or patch of tough, imperforate, foldable material is secured to the upper surface of the pad in such a way that the adhesive-coated surface of the pad defines a border zone extending outwardly about the entire perimeter of the shield. A fold line, preferably defined in part by a pre-formed crease in the shield, extends along the midlines of the pad and shield so that a used syringe may be adhesively secured to the pad with the syringe axis lying along the midline of the pad and the tip of the syringe needle located along the midline of the shield. When the pad is folded about the syringe, the needle is encased between the folded side walls of the shield which in turn are held together by portions of the pad's adhesive-coated upper surface brought into sealing engag…
