Abstract
A non-rotatable axially translatable anterior guard exposes, upon posterior translation along a needle supporting hub, the anterior end of the needle ready for use. Upon anterior translation of the anterior guard, it lockingly engages the hub to retain the needle therein. A detachable tab creates an aperture in the anterior guard for exteriorizing the needle and upon attachment seals the aperture to isolate within the anterior guard, in combination with the fit between the hub and the anterior sleeve, any body substances remaining with the needle after use. A removable posterior guard encloses the posterior end of the hub to receivingly retain any body substances remaining therewith after use of the needle. The anterior and posterior guards, in combination with sealing tape, permit sterilizing the needle prior to use and isolating there within any body substances after use.
