Title:
DEVICE AND METHOD FOR COMPONENT MEASUREMENT FOR DIALYSIS DRAINAGE
Document Type and Number:
Japanese Patent JP2023112488
Kind Code:
A
Abstract:
To provide a device and a method for component measurement for dialysis drainage capable of accurately measuring concentration of a component to be measured in dialysis drainage.SOLUTION: A component to be measured absorbs light of a first wavelength and emits fluorescent light of a second wavelength, and dialysis drainage includes a measurement inhibition component that absorbs the light of the first wavelength, and emits fluorescent light of a third wavelength. A device 1 for component measurement for dialysis drainage includes: a light source 2 for irradiating dialysis drainage with light of a first wavelength; an absorbance measurement unit 3 for obtaining absorbance from the light intensity of the transmitted light transmitted through the dialysis drainage; a first fluorescent light measurement unit 4 for measuring the light intensity of the fluorescent light of the second wavelength; a second fluorescent light measurement unit 6 for measuring the light intensity of the fluorescent light of the third wavelength; a ratio calculation unit 51 for calculating a ratio of the concentration of the component to be measured to the concentration of the measurement inhibition component on the basis of the results of the measurement by the two fluorescent light measurement units 4 and 6; and a component-to-be-measured concentration calculation unit 52 for calculating the concentration of the component to be measured in the dialysis drainage on the basis of the ratio of the concentration calculated by the ratio calculation unit 51 and the absorbance in the first wavelength measured by the absorbance measurement unit 3.SELECTED DRAWING: Figure 3
