便携式哮喘检测系统的研究
Study of the Portable Asthma Monitor System
摘要
Abstract
Traditional diagnosis of asthma relies on accurate data of lung function tests performed by the doctors in hospital using the spirometer,unfortunately it is not only expensive but also hugely inconvenient.And mechanical peak flow meters can be used by the patients at home for test but there are high error rates in data produced and recorded by the patients.Based on above shortcomings,this article describes the systematic design of a portable home electronic asthma monitor which measures peak expiratory flow (PEF) and forced expiratory volume in one second (FEV1),and provides data for the diagnosis of asthma.The system consists of flow sensor,pressure sensor,signal conditioning module,TFT display module,SD card storage module and microcontroller.The expiratory flow sensor was designed and calibrated.The result of test shows that the system can measure PEF and FEV1 rapidly,which has practical application value in premorbid monitoring and prediction.关键词
