基于智能终端的血氧信号采集装置设计

A design of Blood Oxygen Signal Acquisition Device Based on an Intelligent Terminal

血氧饱和度是指血液中氧合血红蛋白(Hb O2)的容量占全部血红蛋白(Hb)容量的百分比,即血液中血氧的浓度。通过对人体血氧饱和度的检测,能够有效的判断人体循环系统和呼吸系统的功能是否正常。目前指夹透射式检测技术发展已相对成熟,但这种检测方法,只适用于对住院病人的监护,而无法进入社区乃至家庭。因此本文基于对反射式血氧饱和度的实时检测硬件装置的研究,结合消除干扰的算法,设计出一种适用于家庭和社区的基于智能终端便于携带的血氧饱和度检测装置。

Oxygen saturation refers to the percentage of the capacity of oxygenated hemoglobin（Hb O2） in the capacity of total hemoglobin（Hb） in blood, namely, the concentration of oxygen in the blood. The detection of human blood oxygen saturation can effectively judge whether the human circulatory system and the respiratory system is normal. Now the development of transmission type detection technology has been relatively mature. However, this kind of detection method is only suitable for inpatient care, but not for community and family. So in this paper, based on the researches on blood oxygen saturation real-time detection hardware device, combining with the algorithm to eliminate interference, an oxygen saturation detecting device which is suitable for family and community was designed.
