一种基于压力传感器的穿戴式呼吸监测系统设计

摘要

为指导慢性阻塞性肺疾病( COPD)患者完成标准的呼吸操康复训练,设计了一种穿戴式呼吸监测系统,系统包括呼吸波传感器、数据采集电路板和手机APP软件.通过该系统,患者能实时观测自身呼吸波形和各项呼吸参数,通过比对标准呼吸曲线,根据同步提示音修正并完成标准呼吸操.临床实验表明:患者使用该系统锻炼可增加肺部通气量,改善肺功能.%A wearable respiration monitoring system is designed to help COPD patients complete standard breathing exercise,and system includes respiratory wave sensor,data acquisition circuit board and an application ( APP)software in cell phone. respiratory waveform and respiratory parameters can be shown in real time to patients,compared with standard waveform,according to synchronization prompt tone to correct and complete breathing exercise. Clinical trials prove that this monitoring system can increase lung ventilation of COPD patients and improve their lung function.
