Abstract
近20年来,近红外光谱技术因具有无创、实时等特点,被广泛用于人体监测.氧作为人体主要新陈代谢物质,在脑组织中消耗量最大,为防止患者治疗时出现脑组织氧降低而出现并发症,需要实时监测患者的脑组织血氧饱和度.目前临床使用的脑血氧无创检测设备大多采用双波长,在探测路径上其他物质会对测量结果产生误差,为此该研究基于近红外光谱无创监测脑血氧的基本原理,提出一种三波长探测光源的脑组织氧饱和度监测方法,并通过所搭建的系统进行初步验证,为后续的系统工程化奠定基础.
In the past 20 years,near infrared spectrum technology has been widely used in human body monitoring due to its non-invasive and real-time characteristics.Oxygen,as the main metabolic substance of the human body,is consumed the most in brain tissue.In order to prevent complications caused by a decrease in brain tissue oxygen during treatment,the patient's brain tissue blood oxygen saturation needs to be monitored in real time.Currently,most of the clinically used non-invasive cerebral blood oxygen detection equipments use dual wavelengths.Other substances on the detection path will cause errors in the measurement results.Therefore,this article proposes a three-wavelength method based on the basic principle of non-invasive monitoring of cerebral blood oxygen using near-infrared spectrum.The brain tissue oxygen saturation monitoring method of detecting light sources was initially verified through the built system,laying the foundation for subsequent system engineering.
