摘要
根据医用电气设备电磁兼容测试标准要求,中频治疗仪的患者耦合部分在进行传导发射试验时需接入模拟手和电阻电容(RC)元件。然而,现有测试标准对模拟手的连接方式阐述不够详尽。通过对工作原理不同的两种中频治疗仪进行传导发射测试,对比测试结果并分析,从而给出此类设备进行该项试验时模拟手和RC元件连接方式。
According to the requirements of the electromagnetic compatibility testing standard of medical electrical equipment,artificial hand and RC element should be connected to the patient coupling part of the medium frequency electrotherapy stimulator during the conducted emission test.However,the existing test standards do not describe the connection modes of the artificial hand in detail.By comparing and analyzing the results of conducted emission tests on two types of medium frequency electrotherapy stimulator with different working principles,the idea and suggestion of the connecting way of artificial hand and RC element in the test of this kind of equipment were proposed.
