    • A used needle is inserted in a housing of a needle apparatus disabling device. As the needle is pushed downwards sealing a collar opening and bears against a stationary cutter blade. The needle is pushed further into the device where it contacts upper and lower electrodes. An electric current passes through the needle, which causes it to become heated resistively to destruction. A voltage drop between the electrodes is detected by a processor activating a motor driven movable cutter blade which then severs a remaining stub or remnant of the needle portion and simultaneously urges the severed stub downwardly onto the electrodes to ensure its complete destruction. During this process any sparks or airborne contaminants, or combustion gases are prevented from escaping through the opening by the sealing action of the apparatus.
    • 使用针插入针装置禁用装置的壳体中。 当针被向下压下时,密封套环开口并且抵靠固定刀片。 针被进一步推入到其接触上电极和下电极的装置中。 电流通过针,导致其被电阻加热破坏。 通过处理器激活马达驱动的可移动切割刀片来检测电极之间的电压降,其然后切断针部分的剩余短截线或残余物,同时将切断的短截线向下推到电极上,以确保其完全破坏。 在此过程中,通过设备的密封作用,可防止任何火花或空气传播的污染物或燃烧气体通过开口逸出。
