A safety needle accessory is provided for the prevention of needle stick injuries. The safety needle accessory includes a hollow needle, a hub surrounding a base of the hollow needle, a sleeve surrounding the hub, and a elastically deformable member. The sleeve is slidable to a first, a second and a third position in which the sleeve fully or partially covers the needle. In addition, the safety needle accessory includes a pack having a removable cap. The cap is removable from the pack while a remainder of the pack remains mounted over the needle, hub and sleeve. The cap is removed from the pack at a position such that removal of the cap exposes a sharp end of the needle, but not the sleeve, when the sleeve is in the intermediate position.
