摘要
本文根据红外光谱法血氧饱和度测量原理,以STC单片机为开发平台,基于光电容积脉搏波描记法(Photo Plethysmo Graphy,PPG),设计一种便携式脉搏血氧仪。作者对血氧探头的设计、信号处理模块的电路设计与算法设计进行研究,提高了血氧饱和度的检测精确度,并通过无线通信传输到计算机上。
According to the ment, on STC microcontroller as principle of the infrared spectroscopy of blood oxygen saturation measure the development platform, we designed a portable pulse oximetry combined with PPG （photoplethysmograph）. The design of blood oxygen probe, the signal processing module circuit design and algorithm design improved the blood oxygen saturation detection accuracy, and the design used wireless communication transmitting to the computer.
