Abstract

A syringe for an injector utilizes a cylinder having a deformable wall portion in the outlet end. Excessive pressure within the syringe cylinder, or contact with the syringe piston at the end of its stroke distends the deformable wall portion of the cylinder, actuating a sensor which provides a signal.
