摘要

针对人体运动病的研究要求，提出了利用内耳血氧含量及血流量变化作为检测参数的系统。在波长分别为660nm和805nm处，利用氧合血红蛋白和去氧血红蛋白对近红外光的吸光系数不同的原理，依据朗伯-比尔定律推导出适于血氧含量及血流量变化检测的工程公式。设计的传感器实现了测量内耳组织血氧饱和度和血流量变化两种人体生理信号的采集和转换，并通过输送数据到PC机，实时反映二者的曲线，为人体眩晕的判断提供较有力的理论依据。

Abstract

This article presented a system of detecting the transformation of oxyhemoglobin(Hbo) and blood flow of inner ear for the research of motion sickness. Based on the different absorption parameters of oxyhemoglobin and deoxyhemoglobin with a near infrared spectroscopy (NIRS) wavelength:660nm and 805nm

a set of engineering formulae were derived for detecting oxyhemoglobin(Hbo) and blood flow from Lambert—Beer Law. The sensor can detect and transform two kinds of transformation human physiology parameters：blood oxygen saturation and blood flow of inner ear. Through transportation data to PC

the system real-time displayed the curves of two parameters and offered forceful theoretic proofs for estimation of vertigo.
