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.
