A hypodermic syringe needle destroying apparatus and method using electrical resistance heating between electrodes which are convergent either geometrically or by virtue of relative movement to conduct incinerating currents first throughout the entire length of the contaminated needle and thereafter

A hypodermic syringe needle destroying apparatus and method using electrical resistance heating between electrodes which are convergent either geometrically or by virtue of relative movement to conduct incinerating currents first throughout the entire length of the contaminated needle and thereafter over progressively shorter lengths until the entire needle is destroyed. Any remaining needle stub can be removed or deformed while in its heated state by impacting it against a deforming barrier.

A method for destroying and sterilizing used hypodermic needles comprising the steps of causing an electrical current to flow through substantially the full length of the needle shaft from hub to tip in an amount sufficient to heat the needle shaft to incandescence and partial destruction, and there

A method for destroying and sterilizing used hypodermic needles comprising the steps of causing an electrical current to flow through substantially the full length of the needle shaft from hub to tip in an amount sufficient to heat the needle shaft to incandescence and partial destruction, and thereafter progressively passing current through what remains of the needle shaft from the hub outward until substantially the entire needle shaft is reduced to sterilized bits to a point adjacent the hub.
