Detection Technology and Application of SpO<sub>2</sub> Based on Dual Wavelength System

Abstract

With the development and progress of the society, people's physical health is getting higher and higher. Enjoy superior in material life and all kinds of disease of heart head blood-vessel also shows high trend. To solve these problems are involved in one of the important parameters- the blood oxygen saturation of body. For application object and environment, The author used fixed double wavelengths red light infrared collection principle. On the premise of not traumas continuous real-time detection.The research, with AT89S52 SCM as cybernetics core, analyses each unit of the structure function and the realization methods and completes commissioning of hardware system .The research,with AT89S52 SCM as cybernetics core, analyses each unit of the structure function and the realization methods and completes commissioning of hardware system. The way can erasure reliability and anti-interference, but also reduce the cost of instrument, in order to fulfill the demand of public. tests show that: this device has speedily test, high sensitivity and accuracy to the requirements of experiment calibration
