医疗设备中开关电源的隔离和应用

Isolation and Application Analysis of Switching Power Supply in Medical Equipment

现以信息技术设备开关电源为例,依其与医用标准在电气隔离程度上的差异,分析非医用电源在医疗设备中使用时需要采取的附加安全措施,并根据设备中患者防护路径上的隔离方式,讨论电介质强度测试时的具体实现方式。

Taking the switching power supply for information technology equipment as an example, according to the difference between it and medical standard in the degree of electrical isolation, additional safety measures for non-medical power supply in medical equipment are analyzed. According to the isolation mode of patient protection path in the equipment, the concrete implementation method of dielectric strength test is discussed.
