Abstract
Abstract A safety syringe having both apparatus for shielding the needle and apparatus for removing the needle after it is used. The apparatus for removing the needle is an elongated member that includes means for grasping the needle and removing it from the syringe body. An elongated cavity is disposed in the extension arm extending from the piston member of the syringe for receiving and storing the apparatus for removing the needle. The apparatus for shielding the needle is a cylindrical member that is attached over the syringe body and movable to and from an extended position over the needle. The safety syringe prevents inadvertent exposure of the needle prior to, during and after use of the syringe.
