HAND-HELD MEDICAL SYRINGE ACTUATOR DEVICE ABSTRACT The invention is directed toward a hand-held syringe actuator and removable syringe. The syringe actu- ator includes a stationary part which removably receives a flange of the syringe barrel and a movable finger part which removably receives a flange at the end of the syringe plunger. The finger grip is movable upon application of finger pressure, but is spring biased to urge the plunger into the syringe barrel. A valve operating stem, carried by the actuator, slidably extends through the finger grip and through the plunger, extending into the syringe barrel and terminating in a valve element. The valve element is sized to seat in a valve seat provided in the syringe barrel at the closed end of the barrel. A spring urges the valve member to remain seated on the seat. The device is con- structed so that it can be held and manipulated by the use of only one hand.
