近年来,慢性疾病人数骤增与医疗资源匮乏之间的矛盾引起了无线体域网在医疗领域的广泛应用。将透射式指端脉搏血氧饱和度采集节点与Android智能终端系统相结合,对光电容积脉搏波进行采集,利用近红外光谱吸光度强弱与物质化学成分信息之间呈现线性相关的特性,对人体体征参数中的脉率和血氧饱和度进行检测。实验结果表明,该节点体积小,功耗低,抗干扰性强,能够无创伤,快速准确地对脉率和血氧饱和度进行实时性监测,并实现数据的无线传输,适合在家庭中使用。
In recent years, the sudden increase in the number of chronic diseases and the scarcity of medical resources have caused the widespread use of wireless body area networks in the medical field. By combining the transmission fingertip pulse oximetry node with the Android intelligent terminal system, the photoplethysmography pulse wave is collected. By using the near-infrared spectroscopy absorbance intensity and the linear relationship between the chemical composition information, Signs and parameters of the pulse rate and oxygen saturation detection. The experimental results show that the node is small, low power consumption, strong anti-interference, non-invasive, fast and accurate real-time monitoring of pulse rate and oxygen saturation, and wireless data transmission, suitable for use in the home .
