一、概述多参数生理信号模拟器作为多参数监护仪计量校准的重要工具,直接关系到医疗诊断的准确性。而2014年新出台的JJF1470-2014《多参数生理模拟仪校准规范》虽然阐述了多参数模拟器的校准方法,但其操作复杂,并且心电幅值测量指标较低,给多参数生理信号模拟器的计量校准造成不少问题。本文针对这一情况,通过对多参数生理模拟器发出信号(主要是心电信号)的性质和特点的研究,归纳出其参数特点,并依据统计学原理,提出了测量方法
First, an overview Multi-parameter physiological signal simulator as an important tool for multi-parameter monitor measurement and calibration, is directly related to the accuracy of medical diagnosis. The 2014 new JJF1470-2014 “multi-parameter physiological simulator calibration norms,” although described multi-parameter simulator calibration method, but its operation is complicated, and the ECG amplitude measurement index is low, to multi-parameter physiological signal simulation Meter calibration caused many problems. In this paper, in view of this situation, through the study of the nature and characteristics of multi-parameter physiological simulator signaling (mainly ECG), the characteristics of its parameters are summarized, and based on statistical principles, the measurement method
