ABSTRACT:
A pistol-like casing provides for mounting a tubular holder containing a syringe in the gun barrel portion of the casing so it may be cocked in the withdrawn position against the force of a spring and released by movement of an arresting pawl. Pulling back a trigger advances a push rod that first trips the pawl, then brings force to bear against the piston rod of the syringe. After the needle is driven into the skin by the release of the pawl and the actuating mechanism has been brought to bear against the syringe piston-rod, the injection of the syringe contents can proceed under control of hand feel without any necessity of changing or shifting the hand grip, by simply continuing to pull the trigger back.
