[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.
