1. Fluid injection apparatus for use with a syringe, the fluid injection apparatus comprising:
- an injector head having a housing defining a front opening therein and drive means extendible through the front opening of the housing for imparting motive force to a plunger disposed within the syringe; and
a pressure jacket assembly for holding the syringe to the injector head, the pressure jacket assembly comprising;
a jacket cylinder having an open front end and a rear end coupled to the injector head;
a first tie rod having a read end attached to the injector head and a front end;
a first front plate attached to the front end of the first tie rod, the first front plate pivotable between a closed position for holding the syringe within the jacket cylinder and an open position for allowing the insertion and removal of the syringe,a second tie rod having a rear end attached to the injector head and having a front end; and
a second front plate attached to the front end of the second tie rod and pivotable between a closed position for holding the syringe within the jacket cylinder and an open position for allowing the insertion and removal of the syringe.

Abstract
The pressure jacket systems of the invention are used to permit the front loading and removal of a syringe from an injector and include a first jacket segment and a second jacket segment surrounding the exterior surface of the syringe, interior surfaces comformable to the exterior surface of the syringe, a mechanism which allows movement of the first jacket segment in relation to the second jacket segment to permit insertion and removal of the syringe from the pressure jacket, and a mechanism for securing the first and second jacket segments in a fixed relationship upon insertion of the syringe.

8. A fluid injection apparatus for use with a syringe, the fluid injection apparatus comprising:
-
an injector comprising a housing defining a front opening therein and drive means extendible through the front opening of the housing for imparting motive force to a plunger disposed within the syringe; and a pressure jacket assembly associated with the housing for substantially enclosing the syringe during an injection procedure, the pressure jacket assembly comprising; a jacket cylinder having an open front end for receiving the syringe therethrough and a rear end coupled to the injector housing; at least one support member comprising a front end and a rear end, the rear end of the at least one support member coupled to the injector housing; and a front member coupled to the front end of the at least one support member, the front member pivotable between a closed position for retaining the syringe within the jacket cylinder and an open position for allowing the syringe to be inserted into and removed from the front end of the jacket cylinder, the front member engaging a front wall of the syringe to retain the syringe within the jacket cylinder. - View Dependent Claims (9, 10, 11, 12)
