资料介绍

为了实现血氧饱和度的动态检测,设计了基于S3C2440A处理器的无创血氧检测系统。该系统以S3C2440A为控制核心,对血氧传感器的信号进行实时分析和处理,并通过串口发送至上位机。依据近红外光谱分析技术的无创血氧检测的原理,设计了血氧饱和度检测传感器,根据传感器的高阻抗特性,设计了驱动电路、血氧信号调理电路及高精度的信号转换电路。该系统实现了血氧信号的实时无创检测,具有快速性、可靠性和较高的精准度。

A non-invasive measuring system based on S3C2440A is designed for dynamic measurement of blood oxygen saturation.S3C2440A as eontral core of the system,analyzed and processed the signal of blood oxygen saturation ,sent the result to upper computer throught the serial. Oxygen saturation of blood sensor is designed based on the principle of non-invasive oxygen saturation of blood detection of near-infrared spectroscopy.According to the characteristic of the high impedance of the sensor,the driver circuit,the oximetry signal conditioning circuit and high-precision signal conversion circuit were designed. The system is non-invasive detection of blood oxygen saturation signal rapidity,reliability and high accuracy.
