基于近红外光的无创血红蛋白含量检测系统设计

Design of Noninvasive Hemoglobin Detection System Based on Near Infrared Light

为了实现无创快捷的人体血红蛋白定量检测,为医生和病人带来方便,设计并实现了一套基于近红外光的无创血红蛋白含量检测系统。系统通过测量人体手指处的漫反射光谱,对血液中各物质浓度和光吸收度进行回归分析,从而定量检测血红蛋白含量。对实验对象的测量结果与标准值的相对误差在7%以下。实验结果说明该系统设计方案合理,能够用于人体血红蛋白含量的检测。

In order to achieve a noninvasive and rapid detection of human hemoglobin,and bring convenience for doctors and patients,a non-invasive hemoglobin detection system based on near-infrared spectroscopy was designed and implemented.By measuring the diffuse reflection spectrum at the human finger,the system performs regression analysis of the concentrations and light absorbance of various substances in the blood to quantitatively detect the hemoglobin content.The relative error between the measurement result and the standard value of the experimental object is below 7%.The experimental results show that the system design scheme is reasonable and can be used to detect human hemoglobin.
