ABSTRACT:
A pistol grip syringe (10) with a removable fluid container (16) is described. A piston (18) in the container separates from a driving rod (19) when the container is removed from the collar (56). The container is removed from the collar by turning one-quarter turn or less to unlock ears 16a on the container from the collar. A wedge (58) holds the rod in position during dispensing and is unlocked to pull the piston rearward in the container. The container can be disposable and the unit is easily cleaned.
