摘要
简述了IT(information technology)类设备与医疗类设备中关于电源部分的差异,包括电介质强度、漏电流、爬电距离和电气间隙等。通过分析电气安全法规要求的要素,并以IT类电源应用于医用超声系统的实例,阐明了IT类电源在医疗产品设计和制造中需要研发和测试的指标。医疗设备的设计开发、产品测试及实际应用均可参考。
This paper describes the specific requirements of power supply between information technology equipment and medical equipment, including insulation, leakage current, clearance and creepage. It is very important for realizing the difference of them. We have analyzed the characteristics of IT power supply in the medical ultrasound system. It can be used for developing, testing and using of medical equipment.
