1、一種體域網(wǎng)無線心電監(jiān)護(hù)系統(tǒng)研制和測試 摘要:隨著中國老齡化和家庭空巢化的加劇,患有慢性疾病的老人在醫(yī)院外的健康監(jiān)護(hù)問題變得日益突出。這就需要人們能夠設(shè)計(jì)出有別于傳統(tǒng)醫(yī)療儀器的新系統(tǒng),這樣的新系統(tǒng)稱為體域網(wǎng)系統(tǒng)。論述了體域網(wǎng)無線心電監(jiān)護(hù)系統(tǒng)的設(shè)計(jì)方案,重點(diǎn)介紹了患者系統(tǒng)以及預(yù)警系統(tǒng)的構(gòu)成。患者系統(tǒng)采用便攜式心電檢測模塊來采集患者的心電信號(hào);藍(lán)牙短距無線通信技術(shù)用于將實(shí)時(shí)心電信號(hào)傳輸?shù)街悄苁謾C(jī);預(yù)警系統(tǒng)能接收患者系統(tǒng)發(fā)送的心電信號(hào)。最后給出了在醫(yī)院環(huán)境中對(duì)系統(tǒng)進(jìn)行的三項(xiàng)測試結(jié)果。關(guān)鍵詞:體域網(wǎng);無線
