Abstract
The fluid injection apparatus for use with a syringe includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one support arm associated with and extending outward from the housing. A syringe retaining member is attached to the at least one support arm. The syringe-retaining member defines a syringe receiving slot for receiving at least a portion of the syringe. A light source is located on the support arm and faces the pressure jacket for illuminating the syringe. The syringe includes an alignment flange defining a bulged air bubble viewing window (see A). The alignment flange is used to properly orient the syringe in the pressure jacket.
