摘　　要：介绍了静电放电的测试要求和测试原理,归纳了花屏、死机、通信中断、误报警等医疗电气设备静电放电常见问题,并结合实际案例,采取了增加板层、增加TVS管、接地去耦、处理USB接口等医疗设备常用的静电整改措施。整改后的产品通过了静电放电测试。The principle and requirements of electrostatic discharge（ESD） test are introduced,and the common problems of medical electrical equipments caused by ESD,such as blurred screen,halted system,interrupted communication,false alarm,are summarized. Finally,the commonly used ESD rectification measures of the medical equipments,such as increasing PCB layers,adding TVS,earthing,decoupling and improving USB interface,are explained by analyzing the actual failing cases. The medical electrical equipments passed the ESD test by adopting the rectification measures.
