FLUID INJECTION APPARATUS HAVING A SYRINGE PRESENCE SENSOR
First Claim
1. A fluid injection apparatus for use with a syringe, comprising:
- an injector comprising a 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 adapted to be engaged by the syringe when the syringe is loaded into the pressure jacket, the syringe sensor adapted to generate a signal indicating the presence of the syringe in the pressure jacket.

Abstract
The fluid injection apparatus is adapted for use with a syringe and includes an injector and a pressure jacket associated with the injector. The injector includes a housing defining an opening for a drive piston extendable from the housing. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a distal end defining a syringe receiving opening for receiving the syringe, and a proximal end associated with the housing and generally aligned with the opening. The apparatus includes a syringe sensor adapted for engagement by the syringe when loaded into the pressure jacket. The housing may have an engagement tab adapted to engage an engagement recess in the pressure jacket to removably engage the pressure jacket with the housing. The apparatus may have one or more light sources associated with the housing for illuminating the syringe received in the pressure jacket.
