摘要
脉搏血氧仪是一种广泛应用于临床的人体动脉血氧饱和度检测仪器。本文建立了一种用于检验和标定脉搏血氧仪的脉搏血氧饱和度光仿真系统。通过对不同部位人体组织光学特性的测定和研究,建立了与组织光学特性基本相近,由复合材料散射膜与光调制器组合而成的脉搏血氧饱和度活体组织仿真光传输模型,实现了不同部位组织的光散射特性和血氧饱和度的仿真。
Pulse Oximetry is an important instrument in clinic.This paper introduced a type of simulator,which can calibrate and test pulse oximetry.This simulator was a model system of human tissue,it had the same optical absorption and scattering property with human tissue.It was capable of generating relevant wavelengths optical signals similar to that pass through the different human tissue.These pulsatile signals can give different oxygen saturation levels,pulse rates and different amplitude of pulse wave.
