摘要
本文研制了一种新型的脉搏血氧监护仪。为了实现连续准确地计算血氧饱和度，在该监护仪中采用了减小背景光干扰的电路和微分阈值计算处理方法。该仪器由光源控制电路、信号放大器、８０９８单片机和液晶显示器（ＬＣＤ）所组成。本文对电路原理和软件设计作了详尽的叙述。
This paper presents a new kind of pulse oximeter monitor.In order to continuously and accurately calculate the blood oxygen saturation,circuits for minimizing the effects of the background light and the differential threshold algorithm are used for the patient monitor The instrument consists of the light source control circuit,the signal amplifier.the single chip computer 8098,and the liquid crystal graphic display(LCD);The electronics circuit principle and the software design are explained in great detail.
