An injection apparatus uses a guide threaded shaft (26) of a main body (20) and an operative knob (34) screw of a movable body (30) to move the movable body (30) relatively to the main body (20). An ampoule (70) is inserted in an ampoule holder (36) of the movable body (30) in a radial direction. The ampoule (70) is first held temporarily by an elastic wing (36a) and then a flange (75) thereof is inserted into a flange receiving portion (38). By turning the operating knob (34), the movable body (30) moves together with the ampoule (70) toward the main body (20). A guide sleeve provided in the main body (20) is inserted in a syringe (77) of the ampoule (70). An injecting knob (50) is turned to set a stroke of a piston rod and then pushed in to inject. A release button (40) is then pressed to return the piston rod to the home position. This apparatus facilitates attaching of an ampoule and observing of the solution in the ampoule. <IMAGE> |
