Abstract
A resuable safety module-activator reshielding tool having a barrel within which to receive a single use, disposable, needle/medication cartridge from which a pre-filled supply of fluid medication is injected. The cartridge includes a needle cannula that is advanced outwardly of the barrel to administer an injection and retracted inwardly of the barrel at the conclusion of the injection. The cannula is crushed, shielded and discarded all within the cartridge so as to permit a safe handling thereof after use and avoid an accidental needle stick. The activator tool cannot be reused until the injection has been completed, the cannula destroyed and shielded, and the cartridge removed from the barrel for disposal.
