Title:
OPTICAL PROBE FOR MEASURING BLOOD FLOW, AND ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2024/053242
Kind Code:
A1
Abstract:
This optical probe for measuring blood flow comprises a tube, a fixing member, a first optical fiber, a second optical fiber, and a reflecting member. The fixing member is inserted into the tube and fixed to the inner peripheral surface of the tube. The first optical fiber is fixed to the fixing member. The second optical fiber is fixed to the fixing member. The reflecting member reflects light output from the first optical fiber, in a direction intersecting with the longitudinal direction of the tube, and reflects light incident from the direction intersecting with the longitudinal direction of the tube toward the second optical fiber. The fixing member includes a fitting recess into which the reflecting member is fit.
