Abstract

Syringe, which is intended for use only once and then to be destroyed to prevent its re-use has a nozzle at the forward end of the barrel for attachment of a needle;. the rubber piston is fixed to its stem by a number of projections which enter into corresp. cavities in the piston. The latter contains a thin, flexible and elastic stop washer, which causes a breakage of the stem immediately behind the point of anchorage of the stem and the piston, so that the piston is broken away from the stem if any attempt is made to re-use the syringe.
