ABSTRACT:
A safety syringe having a double ended hypodermic needle cannula releasably retained at the distal bore of the syringe cylinder by a pair of jaws. A locking and positioning tip is attached to and movable reciprocally through the cylinder with a piston assembly. As the piston assembly is moved distally through the cylinder to expulse fluid therefrom, the proximal end of the cannula is deflected by and imbedded within the locking and positioning tip. The continued distal advancement of the piston assembly corespondingly drives the cannula and its jaws axially and outwardly from the distal bore of the cylinder, whereby the jaws release the cannula. When the piston assembly is moved proximally through the cylinder, the cannula is retracted within and shielded by the cylinder to avoid an accidental needle stick and render the syringe safe for handling and disposal.
