Abstract
Abstract A needle protection safety package, instead of being enclosed in a pouch or other containment wrappings, has fitted thereto at respective ends thereof caps or sheaths so that both the needle and the end to which a syringe is adapted to mate remain enclosed and sterile. Such an arrangement enables easy transport of the safety needle package and provides convenience for the user at the same time. The safety package is further designed to prevent burring of the tip of the needle as the cap or sheath is removed from the needle portion of the package. The safety device of the safety package incorporates a locking mechanism which prevents contact between the needle and the housing as the housing is pivoted to envelop the needle after use.
