目的：通过对合肥地区某三甲医院所有除颤仪进行电气安全检测，以了解其合格率情况。方法依据国际标准IEC60601.1和国内标准GB 9706.1-2007《医用电气设备》，采用FLUKE电气安全分析仪进行检测。结果15台除颤仪在电气安全保护接地阻抗检测中，有13台超出规定范围，其原因是外壳发生氧化导致接地电阻阻值偏大，通过对外壳金属部分做抗氧化处理后，再次检测合格率为66.67%；其他检测项目的合格率均为100%。结论通过电气安全检测，对检测结果中存在的问题，提出相应的维护方法和对策，以减少此类设备电气安全隐患，提高电气安全合格率。%Objective To obtain information about the qualiifcation rate by detecting the electrical safety qualification of all defibrillator monitors in a 3A grade hospital in Hefei area.Methods According to the International Standard IEC60601.1 and national standard GB 9706.1-2007 "Medical electrical equipment", FLUKE electrical safety analyzer was adopted to detect the electrical safety qualiifcation of all defibrillator monitors.Results Thirteen out of the fifteen defibrillators were found out of the standard range during electrical safety grounding impedance test. The reason was that the external shell was oxidized and resulted in a higher value of ground resistance. After performing the treatment of anti-oxidation on the external metal shell, the qualiifcation rate was 66.67% in the repeated test, the passing rate of other test items was 100%.Conclusion With the electrical safety testing and experimental data as the foundation, corresponding maintenance methods and strategies were proposed to solve the problems found in the testing so as to decrease potential electrical safety hazards and to improve electrical safety approval rate.
