The syringe body (3) is controllably moveable relative to the casing. A hollow needle (13) is connected to the syringe body (3) for movement therewith and extends from the casing (2) for use of the syringe (1). A plunger (14) is reciprocally moveable within the body (3) for drawing liquid into the body chamber (4) and/or ejecting liquid from the body chamber (4) through the needle (13). Control means (22) enables the syringe (1) to draw and/or eject a charge of liquid through the needle, whereupon movement of the syringe body (3) and needle (13) relative to the casing (2) disables the syringe (1).</p> |
