ABSTRACT:
A handheld needle incinerator is self-contained within a portable housing and includes a guideway designed to guide the external walls of a diabetes pen-type injector into the incinerating chamber. Two spaced electrodes are simultaneously engaged by the needle to complete an electrical circuit and cause needle incineration. One electrode is dome-shaped and protrudes through an opening in the other electrode. Surrounding the opening in the other electrode is an annular generally conical surface designed to act like a ramp and lead the end of the needle toward the dome-shaped electrode to cause completion of the electrical circuit.
