AI Technical Summary
Technical Problem
Existing technology cannot accurately detect open or short circuits in interfering electrotherapy devices, which could lead to short circuit damage or open circuit electric shock accidents.
Method used
By detecting the output impedance of the output transformer in the interference electrotherapy device, the processor controls the output state, including normal output and stop output states, and determines whether there is an open or short circuit based on the preset impedance range to avoid misjudgment.
Benefits of technology
Accurately identify open and short circuit situations to avoid damage to electrotherapy devices and electric shock accidents, thereby improving safety.

Abstract
本发明公开了一种开短路保护装置、方法和干扰电治疗仪，涉及开短路保护领域，确定干扰电治疗仪中各个输出变压器的输出阻抗，根据每个输出变压器的输出阻抗来控制这些输出变压器的输出状态，其中输出状态包括正常输出状态和停止输出状态。基于此，若电极片从人体皮肤表面脱落，此时该电极片对应的输出变压器的输出阻抗会与电极片正常贴合在人体皮肤表面时的输出阻抗不同；若两个电极片相互接触，此时输出变压器的输出阻抗也会与电极片正常贴合在人体皮肤表面时的输出阻抗不同，所以通过各个输出变压器的输出阻抗来控制各个输出变压器的输出状态，能够准确地确定出是否存在开短路的情况，避免短路导致的干扰电治疗仪损坏以及开路导致的电击事故。
