一种非接触睡眠呼吸暂停报警装置的研制

摘要

To non-contact alarm the sleep apnea under low physical and mental load condition a device was designed including the modules of minimized bio-radar, signal conditioning, control, alarm and power supply, which can realize the function of non-contat detection of the breathing signal, sleep apnea detection and alarm. Experimental results showed that the device can not only non-contact detection the breathing signal without any sensors or electrodes touching the human body, but also has the advantages of smal volume, low power consumption and low price, which may be widely used in monitor the patients with sleep apnea at home or in the hospital.%为了实现在低生理和心理负荷条件下实现睡眠呼吸暂停的报警，该文设计了一种装置，包括微型化生物雷达、信号调理、控制与处理、报警以及电源五个模块，分别实现人体呼吸信号非接触检测、呼吸信号特征提取、呼吸暂停检测与报警功能。实验结果表明，该睡眠呼吸暂停报警装置不仅无需任何直接接触人体电极或传感器，而且体积小、功耗低、价格低廉，未来可广泛用于家庭或医院睡眠障碍患者的监测。
