【摘要】：近年來老齡化問題越來越嚴重,年老體弱者經常需要體檢或長期監(jiān)護,而就醫(yī)難就醫(yī)貴耽誤了很多人疾病的最佳治療期。計算機和網絡快速發(fā)展,使遠程醫(yī)療成為可能,各跨國企業(yè)和研究機構爭相開展了對遠程醫(yī)療的研究,并真正使其應用到老百姓的生活中。我們在本課題中設計了遠程醫(yī)療監(jiān)護系統(tǒng),主要給年老體弱者提供生理參數(shù)監(jiān)護上的方便,系統(tǒng)體積小、功耗低、便于攜帶,適合長期在家里監(jiān)護生理參數(shù),把數(shù)據(jù)通過網絡傳送到醫(yī)生工作站,減免看病難上的很多不必要的麻煩。 本課題研究的遠程醫(yī)療監(jiān)護系統(tǒng)終端是整個系統(tǒng)的一部分,監(jiān)護儀以ARM9開發(fā)板為核心,Linux操作系統(tǒng)為軟件開發(fā)平臺,包括血壓模塊、血氧模塊、呼吸模塊和心電模塊采集血壓、血氧、脈率、呼吸、心電五個生理參數(shù),在論文中分別討論了硬件和軟件的實現(xiàn),最后進行統(tǒng)一調試。 硬件方面自己設計了血壓值采集模擬電路,利用氣壓力傳感器把氣壓信號轉換成電壓信號,經過放大濾波提取模擬信號送處理器做模數(shù)轉換,主要用到的芯片是AD620AR和TL064。電源模塊采用LM系列芯片為整個系統(tǒng)提供了+12V、-12V、+5V和+3.3V電壓,為系統(tǒng)各個模塊提供電源。呼吸模塊采用胸腹式拉力傳感器、對信號進行調整送入處理器進行模數(shù)轉換。心電模塊我們設計了威爾遜網絡電路和到連選擇電路提供7個不同的心電導聯(lián)。 軟件方面設計了血壓、呼吸模塊的數(shù)據(jù)分析方法提取具體的血壓和呼吸率數(shù)值,血氧模塊對串口讀到的數(shù)值進行解析得到血氧數(shù)值。此外,設計了ADC驅動模塊,能夠實現(xiàn)同時4個通道的采樣,實現(xiàn)各個模塊數(shù)據(jù)的模數(shù)轉換。整個軟件系統(tǒng)采用模塊化結構,對每個模塊設計了統(tǒng)一的軟件接口,便于管理和增減模塊功能。 最后對各個模塊進行了調試,多次測試結果與傳統(tǒng)的測量數(shù)據(jù)進行對比,調整軟硬件上的缺陷,把誤差降低到標準以內。到目前為止,整個系統(tǒng)聯(lián)調完成,系統(tǒng)運行穩(wěn)定,能準確的測試到血壓值、血氧飽和度值、呼吸率和脈率能顯示心電圖,基本達到預期要求,后續(xù)工作會對血氧模塊的硬件和核心處理器做進一步的設計,并考慮增加生理模塊。
[Abstract]:In recent years, the problem of aging is becoming more and more serious. The elderly and frail often need medical examination or long-term supervision, and the difficulty of seeking medical treatment delays the best treatment period of many people's diseases. With the rapid development of computer and network, telemedicine has become possible. Multinational enterprises and research institutions have been competing to carry out research on telemedicine and make it truly applied to the lives of ordinary people. In this paper, we designed a remote medical monitoring system, which mainly provides physiological parameter monitoring convenience for the aged and frail. The system is small in size, low in power consumption, easy to carry, and suitable for long-term monitoring of physiological parameters at home. Send the data to the doctor's workstation via the network, relieving many unnecessary troubles from the difficulty of seeing a doctor. The terminal of telemedicine monitoring system studied in this paper is a part of the whole system. The monitor takes ARM9 development board as the core and Linux operating system as the software development platform, including blood pressure module, blood oxygen module, respiration module and ECG module to collect blood pressure. Five physiological parameters of blood oxygen pulse rate respiration and electrocardiogram are discussed in this paper. The realization of hardware and software are discussed respectively and finally unified debugging is carried out. In the aspect of hardware, the analog circuit of blood pressure value acquisition is designed, the pressure signal is converted into voltage signal by gas pressure sensor, and the analog signal is extracted by amplifying and filtering to send it to the processor for analog-to-digital conversion. The main chips used are AD620AR and TL064. The power module uses LM series chips to provide 12V -12V, 5V and 3.3V voltages for the whole system, and supplies power to each module of the system. The respiratory module uses the chest and abdomen tension sensor to adjust the signal and send it to the processor for A-D conversion. We designed Wilson network circuit and connected selection circuit to provide 7 different ECG leads. The data analysis method of blood pressure and respiration module is designed to extract the specific values of blood pressure and respiration rate in software, and the value of blood oxygen is obtained by analyzing the values read by serial port in the blood oxygen module. In addition, the ADC driver module is designed, which can realize the sampling of four channels at the same time, and realize the analog-to-digital conversion of the data of each module. The whole software system adopts modular structure, and designs a unified software interface for each module, which is convenient to manage, add and subtract module functions. Finally, each module is debugged, the test results are compared with the traditional measurement data, the defects of software and hardware are adjusted, and the error is reduced to the standard. So far, the whole system has been completed, and the system is running stably. It can accurately test blood pressure, oxygen saturation, respiratory rate and pulse rate to show the ECG, basically meeting the expected requirements. Further work will be done to further design the hardware and core processor of the oxygen module and to consider adding physiological modules.
