一种适用于床旁非接触监测睡眠呼吸暂停的报警装置

A Noncontact Bedside Alarm Device for Monitoring Sleep Apnea

目的设计一种床旁非接触式睡眠呼吸暂停监测和报警装置。方法系统硬件主要包括生物雷达传感器、单片机、蓝牙模块、LED灯和蜂鸣器;软件端为Android APP,进行数据处理、显示和报警条件判断。该装置通过生物雷达传感器非接触式采集呼吸、心跳信号,经单片机A/D转换后,由蓝牙模块将数据打包无线发送至手机端APP。结果本研究成功研制出该监测和报警装置。该装置有效探测距离为2 m以上,可靠性高,准确率高达96%。结论本系统能够切实解决用户监测预警睡眠呼吸暂停的基本需求,贴合用户的实际生活,具有广大的应用潜力和市场前景。

Objective To design a non-contact bedside alarm device for monitoring sleep apnea.Methods The system hardware mainly included biological radar sensor,single chip microcomputer,bluetooth module,LED lamp and buzzer.Android APP software was used for data processing,display and alarm condition judgment.The device collected respiratory and heartbeat signals through non-contact biological radar sensor.After the AD conversion of the microcomputer,the data were packaged and sent wirelessly to the mobile APP via bluetooth module.Results The monitoring and alarm device was successfully developed in this study.The effective detection range of the device was more than 2 m with high reliability(accuracy up to 96%).Conclusion This system can effectively solve the basic needs of users for monitoring and early warning sleep apnea,and fit the actual life of users,which has broad application potential and market prospect.
