便携式微型睡眠监测系统的设计及应用

Design and Application of Portable Micro Sleep Monitoring System

通过对睡眠呼吸暂停综合症的病理原理、评价指标以及诊断需求等各方面的研究,设计了一种使用方便、利用无线传输、无扰监测的便携式睡眠监测系统。该系统采用微型气囊结合压力传感器监测呼吸,通过光谱吸收法监测血氧饱和度,利用诊断分析软件评价睡眠质量并给出监测的各项指标和OSAHS的病情程度。分别对呼吸和血氧监测进行了实验测试,试验证明本监测平台具有很好的稳定性以及准确性,可以有效地初步诊断OSAHS的病情,为家庭监护提供了方便。

Through the study of the pathology of sleep apnea-hypopnea syndrome, evaluation indexes, diagnosis requirements and so on, a portable sleep monitoring system was designed, which had the characteristics of convenience, wireless transmission and no disturbance. The system can be assessed by respiration monitoring and pulse oximetry, which is based on the pressure variation in miniature air-bag and spectral absorption method. It provides the value of the apnea-hypopnea index（AHI）, which is used to evaluate OSAHS severity. The experiment of the system＇s stability and accuracy is done, which exhibits good performance, it can diagnose OSAHS effectively and provide convenience for home monitoring.
