Abstract
A single use hypodermic syringe uses a generally cylindrical elongated syringe body defining a center bore and supporting a hollow needle in communication with the center bore. A movable piston preferably formed of rubber or resilient plastic material is sealingly supported within the syringe bore. A driver member extends into the syringe bore and is coupled to the piston by a single use coupling. Several embodiments of the single use coupling are shown which function to preclude any further use of the syringe once the fluid injection operation has been implemented by the syringe.
