ABSTRACT:
A syringe in which a piston is releasably latched to a plunger for reciprocation in a cylindrical barrel, wherby the piston will become disengaged from the plunger upon one cycle of rearward and then forward movement of the plunger and piston in the barrel, followed by subsequent rearward movement of the plunger in the barrel, thus rendering the syringe incapable of reuse. The piston is held to the plunger by latching arms which move to an over-center position between their latched and unlatched positions.
