Abstract

PURPOSE:To accurately perform the time wise control of an extinction curve of a specific dye, by irradiating the tissue of a living body with a light pulse having a wavelength largely absorbed by the specific dye and a light pulse having a wavelength not absorbed by said dye and calculating the plasma extinction rate and stagnation of the specific dye on the basis of the light receiving outputs passing through the light passage of the tissue of the living body to output the same. CONSTITUTION:The first and second light sources 11, 12 respectively generate a light pulse having a wavelength lambda1 high in the absorbancy of a specific dye and a light pulse having wavelength lambda2 having no absorbancy. A photodetector 13 receives the lights allowed to irradiate the tissue 15 of a living body from the light sources 11, 12 and passing through a predetermined light passages. The lights sources 11, 12 contain a CPU 34 as an operation means and driven by a measuring and processing part 20. The value of the specific dye corresponding to the concn. thereof in blood is calculated using operation for removing the blood variation in a living body from a calibration curve preliminarily measured before the injection of the specific dye and the function of a simulation curve in the timewise change of the operation result is operated using a method of least squares and the plasma extinction rate (k) and T-min stagnation rate R% of the specific dye are calculated on the basis of the function.
