Abstract

An animal fluid injector, replaceable syringe and method of replacement of the syringe in the injector are provided in which the syringe (32) is loadable and unloadable into and from the injector through the open front end (35) of a pressure jacket (31) of the injector, thereby permitting replacement without retraction of the syringe plunger drive (100) or disconnection of the injection tubing (65). The syringe (32) is provided with a pressure restraining front end, such as an integral or removable cap (56) with structure such as threads (86) that lock the syringe (32) to the front end of the jacket (31) by mating with threads (85) on the jacket (31). A mechanism (125) in the injector, which includes, for example, a key on cam ring (127) operated by a lever (140) with one hand of an operator, interacts with structure such asymmetrically spaced notches (151-153) on the back end of the syringe (32) to, for example, rotate the syringe and simultaneously translate or rotate a coupling (96) on the syringe plunger (54) into and out of engagement with the plunger drive (100) in the injector.
