Patent Images
1. A syringe for injectors, comprising:
- a cylinder having a deformable wall portion, a longitudinal wall, a first and a second end, an outlet end wall dsposed at said first end, and a neck disposed on said outlet end wall;
a piston, disposed in said cylinder; and
,means, disposed in contact with a region of said cylinder which moves upon distension of said deformable wall portion, for providing an output signal proportional to said distension of said deformable wall portion.

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.
