First Claim
1. A fluid injection apparatus for use with a syringe having an injection section with an injection neck, the fluid injection apparatus comprising:
- a housing defining an opening and a drive piston extendable through the opening for imparting motive forces to a syringe plunger disposed within the syringe; and
a pressure jacket assembly associated with the housing for securing the syringe during an injection procedure, the pressure jacket assembly comprising;
a pressure jacket associated with the housing and aligned with the opening, the pressure jacket comprising a distal end with a beveled portion;
at least one support arm associated with and extending outward from the housing; and
a syringe retaining member associated with the at least one support arm, the syringe retaining member defining a syringe receiving slot for receiving the injection neck of the syringe and viewing at least a portion of the injection section of the syringe, the at least one support arm movable selectively between a first position wherein the syringe retaining member prevents removal of the syringe from the pressure jacket and a second position wherein the syringe is removable from the pressure jacket.

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.
