ABSTRACT:
A method and apparatus for disintegrating and otherwise destroying a syringe needle through total and complete incineration. This apparatus being contained within a housing having an orifice through which a syringe needle is continuously inserted, engaging a first conductive plate shaped and positioned so as to accept a vast majority of all commercial needles, then engaging a movable second conductive plate movable within the housing from a first position immediately adjacent to the first conductive plate to a second position commensurate to the length of said needle, actuating a switch which, when closed, permits an electric current to emanate from a suitable power source to pass between a first and second electrical contact disposed upon the first and second conductive plates such that the needle is subjected to electrical current sufficient to immediately disintegrate it along its entire length with a resultant caplike mushroom cover at the distal end of the needle remnant effectively eliminating needle reuse or leakage of mediation or body fluid.
