Abstract
A blood vessel detection device comprises: a first irradiation unit for irradiating a predetermined site of a subject with light of a first wavelength that is absorbed less by hemoglobin or water and light of a second wavelength that is absorbed more by hemoglobin or water than the first wavelength; a second irradiation unit for irradiating the predetermined site with light of a third wavelength that is absorbed less by hemoglobin; a light intensity detection unit for detecting the intensity of light emitted from the subject at one or more positions spaced apart by a predetermined distance from the light irradiation positions of the first and second irradiation units or one or more contiguous positions; and a control unit that calculates blood vessel depth information, calculates blood vessel angle information, and determines an optimal position for measurement based on the blood vessel depth information and the blood vessel angle information.
