ABSTRACT:
A used hypodermic syringe disposal apparatus is disclosed which is capable of disposing of used syringes so as to render re-use impossible and prevent possible infection resulting from the used syringes during the disposal operation. A pair of collapsing gears are arranged at a position which permits the gears to be meshed together in such a manner to prevent direct contacting between teeth of the gears. A voltage is applied to the gear while insulation is provided between both gears. When the used syringe is thrown into the apparatus, a hypodermic needle attached to the syringe is burnt immediately upon the needle contacting both gears so as to make them short-circuit. Also, a narrow gap is defined between the corresponding teeth of the synchronously rotating collapsing gears so that a syringe barrel may be effectively crushed in the gap while being transferred between the gears.
