摘要
针对传统睡眠监测使用中的一些不足,设计了一种新型的无线睡眠监测仪。采用一种改进的脉冲驱动光电传感器,通过微处理器实时采集受检者的光电容积脉搏波,计算心率和血氧饱和度,将结果以ZigBee的方式发送给上位机,利用Visual Basic语言开发了上位机通信软件。实验结果表明,该监测仪对睡眠干扰小,能真实而准确地获取睡眠相关的生理信号,操作方便且成本低。
Aiming at the traditional sleep monitoring having instrument is designed. An improved pulse is used to drive some disadvantages in application, a new wireless sleep monitoring photoelectric sensor. The photoplethysmogram （PPG） is acquisited by a microprocessor, the heart rate and blood oxygen saturation is calculated in realtime, and the results upper computer in the form of ZigBee communication, where a software is developed using the Visual Basic type testing results indicate that the instrument can objectively obtain primitive sleep-related physiological are transmited to the language. The proto- information with little disturbance, as well as maintain advantages of easy operation and low cost. It has great value to be applied in the hospital or household healthcare fields.
