An improved safety needle, including a needle base, for fixing therein a rigid needle containing a hollow hub at one end, a hollow needle connected thereto and a sharp needle tip at the other end, the base defined by a proximal end and a distal end spaced-apart therefrom, the distal end of the needle base having formed therethrough a first bore concentric to the needle and covering the sharp needle tip, and a cap covering the first bore and rotatably positioned thereover, having formed therethrough a second bore, wherein the cap is rotatable between a first, safe position placing the first and second bores out of alignment and preventing passage of the needle and the sharp needle tip therethrough, and a second, armed position placing the first and second bores in alignment to allow passage of the needle therethrough to expose the sharp needle tip.
