峰值流量仪标定系统

Study on calibration system for peak flow meter

峰值流量仪是家用的哮喘监控仪器。它在临床使用和标定时的差异使得测量结果不够精确。为了提高标定准确度,在分析气体流态的基础上建立了标定系统的数学模型,并应用该模型对新研制出的峰值流量仪进行了标定。

Peak flow meter is a kind of household medical appliance to monitor asthma. The differences between its clinical use and calibration may cause the measurement result to be not accuracy enough. In order to improve the calibration of accuracy, a math model of the calibration system is constructed by analyzing the flow regime. The model is applied to calibrate a newly-invented peak flow meter.
