Title:
BLOOD SUBSTANCE DENSITY MEASUREMENT DEVICE, BLOOD SUBSTANCE DENSITY MEASUREMENT METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2023031627
Kind Code:
A
Abstract:
To provide a blood substance density measurement device capable of stably performing accurate measurement, regardless of variation among individuals in depth of a measurement target part of a living body.SOLUTION: A blood substance density measurement device comprises: a light radiation part 20 for radiating laser light to a region including a measurement target part Mp in an analyte part Mp0; a light detector 30 for receiving reflectance L2 based on the laser light L1 for detecting intensity of the reflectance; a first lens 40 which is arranged between the analyte part and the light detector 30, and on which the reflectance L2 from the specific region Mp in the analyte part can be formed into an image on the light detector 30; and a measurement control part 60 for measuring density of a blood substance in the specific region Mp on the basis of the intensity of the reflectance L2, as density of the blood substance in the measurement target part Pp. The light radiation part 20 can selectively radiate, first laser light for target measurement which is absorbed to a first blood substance being a measurement target substance, and second laser light for reference measurement which is absorbed to a second blood substance which is a reference substance.SELECTED DRAWING: Figure 1
