ABSTRACT:
A guard for encapsulating a needle of a syringe, e.g. for self-administered injections, fits telescopically over the syringe barrel and is slidable relative thereto between an extended position in which the needle is enclosed within the guard and a retracted, preferably locked, position in which the needle is crushed between the syringe barrel and a closed end of the guard. The closed end is preferably formed by an integral end-piece of needle-capture material which the needle partially penetrates prior to collapsing, and may include a plate of needle-impenetrable material.
