Title: BLOOD FLOW SENSOR AND BLOOD FLOW MEASURING DEVICE
Abstract:
Provided is a blood flow sensor in which fluctuations in measurement results are suppressed during blood flow measurements. A probe unit 11 is provided with: a sensor part 21 which includes a laser diode for generating laser light, a photodiode for receiving light, and a sensor housing 27 having a contact surface 44 that contacts a subject, and which emits laser light generated by the laser diode to the subject 82 through the contact surface 44, receives reflected light from the subject 82 through the photodiode, and outputs a signal relating to the amount of light received; a holding part 22 for holding the sensor housing 27 in such a way that the sensor housing 27 is movable in the vertical direction 7 crossing the contact surface 44; and a coil spring 23 by which external force applied to the holding part 22 is absorbed and transmitted to the sensor part 21.
