  • Patent number: 4275628
    Abstract: A device is disclosed for severing both a needle portion and an end nub portion of a syringe. The device includes a receptacle for the cutoff portions and a removable cover. A horizontally movable severing means may be suspended from the undersurface of the cover. Mounted on the cover is a handle which is mechanically linked to the severing means. Actuation or movement of the handle thereby causes horizontal movement of the severing means. By resting the syringe in a shoulder portion of the cover, the needle and nub portions of the syringe extend downward through an opening and are in line with the severing means. Therefore, when the severing means is moved in a horizontal direction, it will necessarily cut off the needle and nub portions.
