Abstract: A hypodermic syringe apparatus includes a contact member having an apertured front plate and a hydraulic cylinder reciprocated mounting plate supports a group of hypodermic needles in slidable registry with the front plate openings, which pierce a liquid absorbent web backing the front plate. Each needle is connected by a flexible tube to an adjustable stroke piston pump where inlets are connected to liquid injectable holding receptacles. The pistons are simultaneously actuated by a motor driven drive cam carrying shaft, the motor being controlled by a handle carried switch to rotate the shaft one turn. The shaft carrying cam also controls the flow of liquid to the handle cylinder, and the absorbent pad is connected to a source of antiseptic. A marking pad is carried by the handle front wall to identify the puncture area. Another form of handle includes a flexible band separably encircling the operator's hand for specialized field use.
