一种新型的测量血样血氧饱和度的系统

A new system for measuring oxygen saturation of sampled blood

本文根据脉搏血氧计的原理设计了一种新型测定血祥血氧饱和度(SaO_2)的光学传感器和小型仪器,这个系统具有尺寸小,重量轻和精度高的特点。实验结果表明,由此传感器所得到的血样中氧容量与临床使用的血气分析仪有很好的相关性(r=-0.972)。

Based on the theory and principle of pulse oximetry, a new optical sensor for measuring oxygen saturation(SaO_2) is developed. The system has the advantages of small size, light weight and higher sensibility. Experimental results showed that the oxygen contents of whole blood derived from the prototype sensor correlates well with the blood gas analyzer for clinical diagnosis (r=0.972).
