97碩士論文:行動式生理訊號即時監測系統之開發

  本研究利用無線藍牙通訊以及3.5G行動網路,開發一套行動式的生理訊號即時監測系統,可監測使用者即時的血氧資料、脈搏資料、血壓資料以及照片等五項資料。監測系統中生理訊號裝置包含Nonin 4 100血氧計、源星2.4G血壓計以及Alive ECG心電圖儀,均搭載藍牙傳輸介面與筆記型電腦進行溝通。生理訊號的上傳採用3.5G行動網路,以HTTP通訊架構將生理訊號傳送至指定監測端進行監測以及U-care健康照護平台生理資料的儲存。為確保ECG生理訊號不因3.5G行動網路頻寬不穩定而造成資料傳遞的遺漏,ECG生理訊號的傳送採用分散式網路傳輸架構,將30秒ECG訊號儲存成檔案,再由遠端以HTTP Request方式傳輸。本研究於怡德養護中心隨機挑選7位住民進行系統初期測試,於回診往返龍潭敏盛醫院的過程中進行生理訊號的即時監測,發現血氧資料的即時監測最為穩定,其次為心電圖資料的監測,而血壓的量測容易隨諸多外在因素而造成量測的失敗。

Development of Vital Signs Monitoring System using Wireless Technologies

  In this study, we use Bluetooth technology and 3.5G to develop a mobile vital signs monitoring system, in which user’s blood oxygen, pulse, blood pressure, ECG, and personal photo can be monitored in real-time. Nonin 4100 pulse oximeter, O-star 2.4G blood pressure device, and Alive ECG device are integrated into a notebook computer using Bluetooth interface. Vital signs are transmitted to specific monitoring site and U-care database through HTTP using 3.5G mobile network. ECG signals may be lost during transmission because of instability of 3.5G mobile network. We developed a decentralized transmission structure in which 30-second ECG signals are stored in files locally and then transmitted to the remote host by HTTP request. To evaluate this system, 7 elderly users tested the system in real application scenario. The results showed that the transmission of vital signs were stable. However, blood pressure measurement often failed because of various external factors.
