Title:
HEMOGLOBIN CONCENTRATION MEASURING SYSTEM, TRANSVAGINAL PROBE, ATTACHMENT, AND HEMOGLOBIN CONCENTRATION MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/210642
Kind Code:
A1
Abstract:
Provided is a hemoglobin concentration measuring system comprising: a transvaginal probe having an ultrasonic wave transmitting/receiving unit that can transmit an ultrasonic wave to a biotissue and receive an ultrasonic echo reflected from the biotissue, a light irradiation unit that can emit light including a plurality of specified wavelength components of a wavelength region from visible light to near infrared light toward a direction parallel to a scanning surface of the ultrasonic wave to be transmitted from the ultrasonic wave transmitting/receiving unit, and a light receiving unit that can receive reflected light or transmitted light that has emitted from the light irradiation unit, and reflected by the biotissue or transmitted the biotissue and propagates from the direction parallel to the scanning surface; a display unit that can display an ultrasonic image including an image of an ovarian cyst on the basis of the ultrasonic echo received by the ultrasonic wave transmitting/receiving unit; and a concentration calculation unit that calculates concentration of hemoglobin in cyst fluid held by the ovarian cyst on the basis of a spectrum of the reflected light or the transmitted light from the ovarian cyst received by the light receiving unit.
