摘要
目的:研究高频电刀分析仪的校准方法,用于该设备在生产和使用过程中的校准。方法:分别采用比对法和间接测量法,在理论上对两种方法进行了分析,并应用这两种方法对实测数据进行分析和处理。结果:对样机在各种不同条件下的功率测量误差(或不确定度)进行测试和分析,结果表明,样机的功率测量误差小于5%。结论:采用对比法和间接测量法,可以得到电刀分析仪的漏电流和峰值因子等参数的测量结果不确定度,该方法可以作为高频电刀分析仪生产和使用过程中的校准方法,也可以作为国内电刀分析仪的溯源方法。
Objective To research the calibration methods of the electrosurgical analyzer which is applied in calibration for production and use of electrosurgical generator. Methods Two methods were put forward, the first one is indirect measurement, the second one is comparing with congeneric device, and these two methods in theory and practice to process real data were analyzed, Results The device with the methods are tested and analyzed, and then, the test error or uncertainly of eleetrosurgical analyzer is used in analyzing and processing. Conclusion The test error or uncertainty of leakage current and peak factor can also get by these two methods, and these methods could be used as calibration method in production and usage of electrosurgical generator or method for tracing the source.
