A cap or sheath locks onto the needle or other sharp, thus permanently inactivating the needle or other sharp, preventing any further use of the device, and permanently isolating the contaminated sharp. Four components are a needle or sharp to accommodate a locking collar, a sheath with a external, internal, or horizontal track to accommodate a locking collar, a locking collar that moves inferiorly within or outside the sheath, or horizontally that binds to the sheath or needle, permanently locking the needle in the sheath and mechanically preventing the needle from moving from the sheath, and a locking mechanisms for these devices. Handles are advantageously provided for the sheath to permit safe recapping or resheathing so that the needle can be bound in the sheath and inactivated. |
