A safety shield for use with a hypodermic syringe device is disclosed. The safety shield is moveable relative to the syringe barrel between refracted position and a needle containing position. In the retracted position, the syringe device may be used to inject the needle into the patient. After the needle has been withdrawn or as the needle is withdrawn from the patient, in its operative mode, the shield extends from its retracted position to a needle containing position to shield the point of the needle to prevent accidental sticks and to render the syringe unuseable after a single injection.
