Abstract

Human body has a high transmittance coefficient for near infrared light. Therefore, dyes with notable absorbance peaks in the near infrared range have a variety of applications in diagnostics. Whereas one of the main liver functions is blood purification, the rate of removal of dye from the blood is direct index of liver functionality. Indocyanine green is used to measure liver function with plasma disappearance rate parameter. Dynamic measurement of dye concentration in human blood allows to calculate plasma disappearance rate. Thereby, our setup is intended to be applied for liver function assessment. In water solution indocyanine green has absorption peak on 790 nm. Absorption analysis method of solution concentration determination is considered. We present spectrophotometry setup for measurement of the dye concentration in solution.
分光光度法测定溶质浓度的装置
人体对近红外光有很高的透过系数。因此,在近红外范围内具有显著吸光度峰的染料在诊断中具有多种应用。虽然肝脏的主要功能之一是血液净化,但从血液中去除染料的速度是肝脏功能的直接指标。吲哚菁绿用血浆消失率参数测定肝功能。动态测量人体血液中的染料浓度可以计算血浆消失率。因此,我们的设置旨在应用于肝功能评估。在水溶液中吲哚菁绿在790nm处有吸收峰。研究了溶液浓度测定的吸收分析法。我们提出了一种测定溶液中染料浓度的分光光度法装置。
