基于医疗设备的电气隔离技术

Electrical isolation technology based on medical equipment

介绍了光电耦合隔离、电磁隔离、继电器隔离、电容器隔离等医疗设备常用的电气控制隔离技术,重点阐述了供电系统的电气隔离、数字信号的隔离、模拟信号的隔离方法。建议在医疗设备研制和安装过程中要综合考虑各方面因素,选择合理的隔离方式,以提高设备的电磁兼容性和医务人员测量的准确度。

Some electrical isolation technologies of medical equipment were introduced, including the technologies of optically coupled isolation, electromagnetic isolation, relay isolation and capacitor isolation. The electrical isolations for the power supply system, digital signal and analog signal were described in detail. It＇s suggested that considerations be taken on the isolation during the development and installation of medical equipment to enhance its electromagnetic compatibility.
