A syringe needle safety cover includes a pair of jaw members pivotally mounted on diametric sides of an adapter which is designed for placement between a conventional syringe barrell and its needle to move between a closed position, wherein the jaws are longitudinally abutting, and an open position. A groove in each jaw cooperates to form a tubular aperture between the jaws into which the needle is encased. The jaws are provided with locking clips which lock the jaws togetehr around the needle. A fluid-tight safety cover is provided by the insertion of a plit-gasket-type seal, one portion of the gasket being attached to each jaw. The gasket material is compressible, such that it will sound a portion of the needle and seal fluids into the tubular aperture. A mechanical actuator may be provided, which includes a pair of lever arms which are connected at one end of each jaw and at the other end to an actuator bar. The actuator bar is thumb-actuated, and moves along the syringe barrel, causing the jaws to open or close, depending upon the direction of movement of the actuator bar. |
