A B S T R A C T A safety syringe, such as a dental syringe, comprising a hollow cylinder, a disposable, prefilled fluid medication carpule received within the interior of the cylinder, and a needle carrying hub supporting a needle cannula so that the cannula extends axially from the carpule and outwardly of the cylinder, whereby to administer an injection. A piston assembly is movable axially through the carpule to first expulse the medication therefrom and to then engage and retract the needle hub and its associated needle cannula into the carpule, so that the needle will be completely surrounded and shielded by said carpule. A slide lock is connected around one end of the medication carpule and interfaced with the needle carrying hub to control the relocation of the hub and corresponding retraction of the cannula through the carpule. The slide lock is selectively moved relative to the carpule between needle retaining and needle releasing positions to either anchor the needle carrying hub with the needle extending axially from the carpule for administering an injection or release the needle carrying hub for retracting the cannula into its carpule to permit a safe disposal of the needle while avoiding an accidental and potentially life threatening needle strike.
