摘要: | 本研究的目的是研製無線生理訊號系統,並且測試此系統的性能。無線生理訊號系統是希望能夠透過網際網路的方式監控此一系統,並且將此系統所得到的數據擷取和分析。所研製完成的無線生理訊號系統可以分為生理訊號感測元件、微電腦運算處理器、藍芽無線模組、整合軟體四個子系統。生理訊號感測元件是利用儀表放大電路作為基礎,以電極貼片所量測到心臟所釋放的微小電壓訊號經過差動和放大以及濾波等動作,得到所謂的ECG訊號,並且利用個人電腦將連續訊號擷取下來,用來作其他的訊號分析和處理。微電腦運算處理器用來主要是用來處理經由生理訊號感測元件所得到的類比訊號,由其內部的AD轉換元件將訊號轉換成16進位的數位訊號。藍芽無線模組則是將所得到的數位訊號以無線的方式將訊號傳回伺服器。整合軟體的工作則是把所得到的數位訊號轉換成的波形訊號,並且即時顯示於監控螢幕上,另一方面整合軟體的工作也需要配合伺服器的設定,使程式介面輸出成為網頁資訊,使醫護人員能以網際網路瀏覽器的方式就可以監控無線生理訊號系統的狀態。目前系統已經成功做出一對三的無線生理訊號監測系統,依此系統的設計方式可擴大至多人架構,每一組可攜帶式硬體的大小約為90×55×20 mm3的大小,並且以藍芽傳輸的方式將心電圖、心率、以及體溫的訊號傳回伺服器端,並且可以透過伺服器的網際網路連線方式,以遠端的方式監視並且控制生理訊號監控系統。 The goal of this research is to develop a wireless physiological monitoring system and to test its performance. The wireless physiological monitoring system was implemented on an internet-based software environment to allow for data acquisition, transmission and analyses. This wireless physiological monitoring system can be divided into four subsystems; a physiological signal sensor component, a microprocessor, a bluetooth wireless module and an integrated software. The physiological signal sensor component is composed of electrode patches and an instrumentation amplifier. Electrode patches is attached to the patient’s heart area. After the electrode patches receive the signal from the heart, the differential signal is measured and then amplified and filtered for the final output of ECG signal. The ECG signal is transmitted to the program running on a personal computer via bluetooth wireless module to capture those signals for future analysis and processing. The microprocessor uses its ADC (analog to digital converter) to process the analog signals received from the physiological signal sensor component and convert it to hexadecimal digital code. The bluetooth wireless module transmits those signals back to the server wirelessly. The integrated software system then converts those digital signals into wave signals and presents them on the monitoring screen simultaneously. On the other hand, the integrated software system also conforms to the server’s setting and presents these data on the websites so that physician and nurses can use the internet browser to get the most recent info of the monitoring system. This physiological monitoring system can monitor three patients at a time and can be extended to more patients. The size of each portable hardware is about 90×55×20 mm3. This portable hardware can detect patient’s ECG signal, heart rate, and body temperature. |
