摘要

The disposable syringe has a syringe body (1) and a syringe piston (2), where the syringe body and a plunger (6) of the syringe piston have a triangular cross section with rounded corners. The reinforcing ribs are arranged in the longitudinal direction on the syringe piston in a radial manner. A conical projection is arranged on an angular or round extension rod (12). The syringe plunger has a predetermined breaking point (10) and is movably fitted in the syringe body. An outlet opening is formed for a needle holder (4) in the region of a syringe head (3).
