Abstract
An animal fluid injector replaceable syringe and method of replacement of the syringe in the injector are provided in which the syringe is loadable and unloadable into and from the injector through the front of the injector, thereby permitting replacement without retraction of the syringe plunger drive or disconnection of the injection tubing. A mechanism in the injector, which includes, for example, a key on cam ring operated by a lever with one hand of an operator, interacts with structure such asymmetrically spaced notches on the back end of the syringe to, for example, rotate the syringe and simultaneously translate or rotate a coupling on the syringe plunger into and out of engagement with jaws of the plunger drive in the injector.
