Front loading injector with pressure jacket assembly
First Claim
1. 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 a drive piston extendable through the front opening of the housing for imparting motive force to a plunger disposed within the syringe; and
a pressure jacket assembly operably associated with the housing for substantially enclosing the syringe during an injection procedure, the pressure jacket assembly comprising;
a jacket cylinder comprising a rear end coupled to the injector housing and an open front end for receiving the syringe therethrough;
at least one support member comprising a rear end pivotally coupled to the injector housing and a front end; and
a front member pivotally coupled to the front end of the at least one support member, wherein the front member is pivotable between a closed position for retaining the syringe within the jacket cylinder and an open position for allowing the syringe to he inserted into and removed from the front end of the jacket cylinder.

Abstract
An injection apparatus for use with a syringe is provided. The injection apparatus includes an injector and a pressure jacket assembly. The injector preferably includes a housing defining a front opening and a drive piston extendible through the front opening for imparting motive force to a plunger disposed within the syringe. The pressure jacket assembly preferably includes a jacket cylinder having a rear end coupled to the injector housing and an open front end for receiving the syringe therethrough, a support member having a rear end pivotally coupled to the injector housing and a front end, and a front member pivotally coupled to the front end of the support member. Preferably, the front member is 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.
