Abstract

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.

摘要

本文提到了一种用于检测常见肺功能参数的便携式设备。该设备以单片机作为主控模块，采集高精度气压传感器的数据并进行处理，通过参数校准和线性插值的方式来测试和计算用力肺活量（FVC）、呼气峰值流速（PEF）、一秒用力呼气容积（FEV1）以及FEV1/FVC。同时，检测到的参数可通过无线传输模块上传至智能移动终端。该设备能够清晰显示呼气容积-时间曲线及最终参数，测量误差小于5%。此外，该设备体积小巧、使用便捷，不仅适用于临床应用，还可在家庭中使用。
