摘　　要：该文介绍了一种可以检测常用肺功能参数的便携式设备的具体实现。该设备采用单片机为主控模块采集、处理高精度气压传感器的气压数据,通过定标参数、线性插值的方法来计算测试用力呼气容量(Forced Vital Capacity,FVC)、峰值呼气流速(Peak Expiratory Flow,PEF)、一秒的呼气容量(Forced Expiratory Volume in one second,FEV1)以及FEV1/FVC值。同时,检测的参数可以通过无线传输模块上传智能移动终端。该仪器能够清晰地显示呼气的容积—时间曲线和最后的参数,测量误差小于5%。该仪器小巧方便,不仅适合临床应用而且也适用于家庭应用。A kind of portable device for detecting common lung function parameters is mentioned in this paper.Using the singlechip microcomputer as the master control block to collect and process the data from high-accuracy gas pressure sensor,through the way of parametric calibration and linear interpolation to test and calculate the Forced Vital Capacity(FVC),Peak Expiratory Flow(PEF),Forced Expiratory Volume in one second(FEV1),and FEV1/FVC.Meanwhile,the detected parameters can be uploaded to the intelligent mobile terminal through the wireless transmission module.The device is able to show expiratory volume-time curve and the final parameters clearly,the error of measurement is less than 5%.In addition,that device is small and convenient,not only is good for clinical application,but also can be used for family in a house.
