ABSTRACT:
A hand-operated syringe for injecting a liquid under high pressure. The syringe has an elongated barrel with proximal and distal ends, the barrel having opposing finger grips at its proximal end with each finger grip having a proximal inner portion defining a most proximal pressure point closely adjacent the barrel, the pressure points defining a plane substantially perpendicular to the barrel's axis. A plunger is received in the barrel and has a proximal end that includes a pressure surface adapted to receive manual pressure. The pressure surface of the plunger and the finger pressure points are arranged so that when the plunger is in its fully inserted position, its pressure surface is spaced distally of the plane defined by the finger pressure points.
