摘　　要：介绍了一种用于检测多参数监护仪呼吸节律的模拟装置,可解决多参数监护仪的呼末二氧化碳浓度示值误差和呼吸频率示值误差两个计量参数检定的问题,该装置采用低压设计,标准气体消耗量低,模拟潮气量、呼气量、吸气量、呼气时间、吸气时间可根据监护仪不同病人工作模式进行调整,可用于多参数监护仪的检测、质保维修、校正等工作。This paper introduces a simulative device for detecting the breathing rhythm of multi-parameter Monitor.It is convenient to realize the calibration of the two measurement parameters of the indicator error of the final carbon dioxide concentration and the indicator error of the respiratory rate of the multi-parameter Monitor,the simulated tidal volume,air volume,inspiratory volume,breathing time and breathing time can be adjusted according to the different patient working mode of the Monitor,and can be used for the detection,maintenance and calibration of multi-parameter monitor.
