Front load pressure jacket system with syringe holder
First Claim
1. A method of mounting syringes on an injector defining a front opening therein and comprising drive means extendible through the front opening for imparting motive force to plungers disposed within the syringes, comprising:
- providing a pressure jacket assembly associated with the injector for substantially enclosing the syringes during an injection procedure, the pressure jacket assembly comprising a jacket cylinder having an open front end for receiving the syringes therethrough and a rear end associated with the injector, at least one support member comprising a front end and a rear end, the rear end of the at least one support member associated with the injector, 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 syringes within the jacket cylinder and an open position for allowing the syringes to be inserted into and removed from the front end of the jacket cylinder, the front member operable to engage front walls of the syringes to retain the syringes within the jacket cylinder;
inserting a rear end of a syringe into the open front end of the jacket cylinder; and
pivoting the front member from the open position to the closed position to retain the syringe within the jacket cylinder.

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.
