Abstract
A medical measuring apparatus having an ultrasonic wave probe adapted to make contact with a body surface and two cathode ray tubes. The probe functions to deliver outputs associated with a blood flow speed and a blood vessel diameter deviation output. An output representing an amount of blood flow is formed on the basis of both the outputs associated with the blood flow speed and the blood vessel diameter deviation output. The output representing the amount of blood flow is displayed on the first cathode ray tube, while the blood vessel diameter deviation output and the pulse output having the width corresponding to the blood vessel diameter are displayed on the second cathode ray tube.
