| Telemedicine is a medical service model in which modern multimedia modern multimedia communication technology is applied for medical and health care. Telemedicine involves medical, communications, computer and and so on, which includes remote consultation, remote consultation and remote monitoring. Telemedicine is an important way to solve the uneven distribution of medical resources and achieve health management. The rapid development of internet and the upgrading of the computer and network access methods make the telemedicine a realization.Family care belongs to remote monitoring. Family care can reduce the medical and pension service pressure of the society and improve the efficiency of the hospital by providing a whenever and wherever health care system. The pulseoximeter is one of the crucial parameters in the home care, which is an important index to keep human respiratory function and oxygen content is normal. Real time detection of pulseoximeter, can timely detect hypoxemia and sleep apnea syndrome. It also has important significance for monitoring stroke, myocardial infarction and fatigue drivingIn the paper, we firstly described the principle for detecting pulseoximeter with optical measurement method and analyzed the necessity of conducting pulseoximeter detection in real time, and then conducted the design and realization research of the pulseoximeter detecting equipment. The work and achievements of the paper are described as follows:1. According to the requirement to detect pulseoximeter in real time,we chose a suitable MCU, and completed the overall design of low power network pulseoximeter detecting equipment, including filtering algorithm and shielding method for various of clutters.2. Gave an analysis of the short distance wireless transmission protocol stack of Zigbee, and completed the design of short distance wireless transmission module. The connection of Zigbee module and pulseoximeter detecting equipment, is a key to realize network pulseoximeter real-time detetion, It is also the unique advantage of the pulseoximeter detection equipment of the paper.3. Completed the software and hardware design of pulseoximeter detection equipment, and realized the extraction of pulse waveform, heart rate and oxygen saturation.At the end of the paper, a summary is given for the network pulseoximeter detection equipment. By comparing and analyzing the performance of the equipment, some tentative ideas to improve equipment availability are put forward, including replacing the transmissive oxygen probe with reflective oxygen probe to expand the range of applitions, and combining the mobile phone platform with physiological signal extraction and transmission to to expand the transmission distance. |
