BLOOD VESSEL SEARCHING DEVICE, ULTRASONIC MEASUREMENT DEVICE AND BLOOD VESSEL SEARCHING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique which can measure the blood vessel diameter accurately by setting the transmission direction of an ultrasonic wave in accordance with the position of a blood vessel.SOLUTION: An ultrasonic measurement device 1 comprises: an ultrasonic measurement control part 210 which transmits an ultrasonic wave to a blood vessel and receives the ultrasonic wave reflected from the blood vessel to create reception data; a blood vessel detection part 220 which detects the blood vessel from the reception data; a transmission direction setting part 230 which sets the transmission direction of the ultrasonic wave for measuring the blood vessel diameter of the blood vessel by using the detection result of the blood vessel position; and a blood vessel diameter measurement part 250 which measures diameter of the blood vessel by transmitting the ultrasonic wave into the transmission direction.
