摘要
睡眠呼吸暂停综合症是心、脑血管疾病的重要诱因之一。本文根据红外测血氧饱和度法对睡眠呼吸状态进行监测的原理，以STM32F103ZET6单片机为开发平台，设计了一种可穿戴式无线睡眠呼吸暂停监控装置。设计中采用红外双波反射式传感器，利用指夹式探头，使使用者在无不适感的状态下进行测量。STM32F103ZET6单片机具有片内A／D转换器，直接将采集到的血氧信号转换成数字信号进行传输。在上位机利用LabVIEW对血氧信号进行实时处理，实现数据的存储以及报警。实际运行表明，本系统具有体积小、功耗低、可穿戴式、无创性等优点。
Sleep apnea syndrome is one of the important cause of heart and cerebrovascular diseases. In this paper, aceording to the method of infrared measuring blood oxygen saturation state of sleep apnea monitoring principle, a wearable wireless sleep apnea monitoring device is designed which developed as the STM32F103ZET6 MCU. This device adopts the reflecting type of infrared double -wave sensor, using clip -on probe, make users to measure under the conditions of no discorntbrt. STM32F103ZET6 MCU has on chip A/D converter, directly to the collected blood oxygen signal into dirital signal. In PC ,the real-time signal is processed by LabVIEW to realize the data storage and alarm function. Actual operation shows that this system has the advantages of small volume, low power consumption, wearable, non-invasive, etc.
