In order to ensure that the blood flow rate test probe 40 can be accurately placed near the artery to detect the accurate blood flow rate, as shown in fig. 1, 2, 5 and 6, the angle adjustment unit 30 is configured to rotate the blood flow rate test probe 40 about an axis perpendicular to the blood flow rate test probe 40. Therefore, the blood flow velocity test probe 40 can be adjusted to form a specific included angle with the detection surface of the color ultrasound probe 80 by the angle adjusting unit 30.

Specifically, as shown with continued reference to fig. 1, 2, 4, and 5, the angle adjustment unit 30 includes an angle dial 31 provided on the first connection unit 20; a rotary hole block 32 having one end pivotally connected to the angle dial 31; and a first locking mechanism 34 capable of locking the other end of the rotating hole block 32 with the angle dial 31; the blood flow rate test probe 40 is provided on the rotary bore block 32, and the axis of the blood flow rate test probe 40 is perpendicular to the pivot axis of the rotary bore block 32.
