Patent ID: 7022112

Claim:
A hand operated syringe for injecting a liquid, comprising: a) an elongated barrel having proximal and distal ends and an exit orifice at its distal end; b) a pair of opposing finger grips for reception of the index and middle fingers, respectively, of a user's hand and carried at the proximal end of the barrel, each grip having a generally distally facing gripping surface having an arcuate portion nearer the barrel than any other arcuate gripping surface portion and defining a most proximal point on said arcuate gripping surface to which finger pressure is applied proximally during operation of the syringe, said points defining a plane substantially perpendicular to the barrel's axis; c) a plunger received in the barrel and having a proximal end protruding from the barrel, said proximal end including a pressure surface adapted to receive manual pressure; the plunger being movable between retracted and fully inserted positions within the barrel to discharge a volume of liquid through the exit orifice, the pressure surface of the plunger and the finger pressure points closely adjacent the barrel being so arranged that when the plunger is in its fully inserted position, its pressure surface is spaced distally of said plane.
