1. An ultrasound diagnostic apparatus comprising:
an ultrasound probe attached to a motion sensor;
a processor; and
a discrimination result memory,
wherein the processor is configured to:
sequentially calculate movement amounts of the ultrasound probe based on values measured by the motion sensor,
sequentially acquire ultrasound images by transmitting ultrasound beams toward a subject from the ultrasound probe,
sequentially detect a blood vessel from the sequentially acquired ultrasound images,
upon keeping calculating the movement amounts that are equal to or smaller than a first predetermined threshold value during a constant time span,
execute a discrimination process of determining whether the detected blood vessel is a vein or an artery, and
store a result of the discrimination process in the discrimination result memory.
