Abstract:
1. A fluid injection apparatus for use with a syringe, comprising: an injector comprising an injector housing defining an opening for a drive piston extendable from the injector housing for imparting motive forces to a syringe plunger disposed within the syringe; a pressure jacket associated with the injector for securing the syringe during an injection procedure, the pressure jacket having a distal end defining a syringe receiving opening for receiving the syringe and a proximal end associated with the injector housing and generally aligned with the opening; and a syringe sensor comprising a tapered actuating member having two ends, a flat end and an elongated end, and an electrical switch, whereby the flat end comes into contact with the syringe thereby causing the elongated end to contact the electrical switch and generate a signal when the syringe is inserted into the pressure jacket.
