基于环绕式血氧探头的睡眠呼吸暂停综合征检测装置原型设计与开发

Peripheral oxygen saturation detecting prototype applied in sleep apnea syndrome

设计制作了基于环绕式脉搏血氧探头的睡眠呼吸暂停综合征(SAS)检测装置原型,与临床上商用指夹式血氧探头进行了外周血氧饱和度(SpO2)测量的实验对比,并通过模拟呼吸暂停对SAS进行了初步检测和结果分析。数据表明,环绕式探头SpO2测量误差均在±1%以内,为SAS自动检测模型提供可靠的数据来源。此装置原型为实现SAS的自动筛查提供了一种新方法。

In this research we designed a prototype of Sleep Apnea Syndrome（SAS）detection device based on the surrounded type pulse oximeter probe.This self-designed device was compared with clinical commercial finger clip type oxygen probe.Furthermore,SAS was preliminary detected and analyzed simulated apnea.The results show that the peripheral oxygen saturation（SpO2）measurement error of this self-designed device is less than ±1%,which meets the requirements of sleep monitoring,thus,can provide reliable data sources for SAS automatic detection model.This device provides a new choice fro SAS screening.
