    Patent number: 5282428
    Abstract: An incinerator for disposing of a syringe needle having a first pair of electrical contacts adapted to connect a source of electricity at approximately opposed positions across the width of the syringe needle such that the electricity will flow across the width between the positions for welding and sealing the needle, and a second pair of electrical contacts adapted to connect a source of electricity to flow across a portion of the length of the syringe needle for incineration of said portion. The present invention ensures that the end of the needle is completely sealed, i.e., sufficiently sealed to prevent any possible leakage of harmful quantities of fluid.
