无创血氧饱和度实时监测系统的研究

Study of a Real-time System for in Vivo Measurement of Blood Oxygen Saturation

本文采用无创光谱技术分析光通过人体指尖组织的传输特性，提出了改进的无创在体监测血氧饱和度的数学模型。着重研究了血氧监测的关键技术问题和解决措施，在此基础上，研制了无创血氧饱和度监测系统，并用本系统进行了在体测试，结果令人满意。

The principle and method of in vivo measurement of blood oxygen saturation (SaO 2) is presented in this paper which analyzes the characteristics of light transmitted through the figertip. Based on this method, a real time system for noninvasive measurement of blood oxygen saturation has been designed and fabricated Furthermore, the key technical problem and solving scheme were studied in details. A real time monitoring system also was set up, the experimental results are satisfactory.
