  • Protective sleeve for hypodermic needle
    Patent number: 5713871
    Abstract: A hypodermic needle having a rigid, clear, protective sleeve encircling the perimeter of the barrel of the hypodermic needle and connected to the plunger of the hypodermic needle, the protective sleeve being drawn toward the bevel of the hypodermic needle as the plunger is depressed. Additionally, the preferred embodiment includes a locking device that locks the protective sleeve in place once the plunger is fully depressed and the injection is complete, preventing reuse of the hypodermic needle and reducing the chance of accidental contact with the bevel.
