摘要
鉴于计算机USB接口拥有的诸多优点,大量由计算机USB口供电的医用电气设备被开发出来。但由于其在供电方式和使用方面的特殊性,此类设备在电气安全方面很难符合相关国家和国际标准。本文通过剖析USB接口的电气特性,结合医用电气设备在电气安全方面的专用标准:GB和IEC,得到由计算机USB口供电的医用电气设备的设计原则,以避免此类设备的设计失败。
Plenty of ultrasonic therapy equipments by USB Power Supply had been developed. Because of its particularity on power supply mode and usage, it is hard to fit the need of GE and IEC.This paper analyses the electrical character of USB, combined with the specialized standard of GB and IEC for the safety of ultrasonic therapy equipments to get its design principles. This work can avoid the failure in designing.
