The Leakage Current Test of Medical Electrical Equipment (2)
International standard GB9706.1 -1995 Medical electrical equipment Part 1: General requirements for safely is the basic safely standard to certification the medical electric equipment at present. This article discusses the standards of leakage current and the patient auxiliary current from medical electronic equipment in detail. Firstly,the article demonstrates the characteristic of the dielectrics through easy charts. Then, it sums up and analyses the principles, types, measuring requests and measurment means of the leakage current causation in studies of current hospital practices. Finally,it uses the High Voltage Therapy Equipment as an example to illustrate how to understand the standard testing procedure. Hopefully this article will be helpful to companies involved in the manufacture of medical electrical equipment and those who use it. Hope the testing fellow trader will point out the shortage at the same time.
