ABSTRACT:
A syringe having a stopper configured at least partly as a membrane surface. The stopper is prestressed opposite to the direction of insertion of a rotary piston so that it assumes a stable position at rest. After displacement by the rotary piston, the membrane surface reversibly returns to this stable position after it is depressurized.
