[0003] Blood vessels are the main transport channels of human life movement, and quantitative analysis and measurement of blood vessel motion caused by breathing and heartbeat movement can assist doctors in implementing precise diagnosis and treatment of diseases. For example, coronary arteries are important pathways for myocardial blood supply, and extraction and motion tracking of the coronary arteries with the aid of image data can realize cardiovascular disease diagnosis and cardiovascular function evaluation, which is helpful to avoid surgical risks.

[0004] When doctors collect image data from patients, a color Doppler probe with a coupling agent needs to be attached to the skin of the patient to be detected, and a 4D dynamic image is generated by moving on the skin of the patient to be detected. The color Doppler probe is an important component of image data collection, and its value is high. However, the connection between the color Doppler probe and the connecting line will inevitably be bent during frequent use, and finally the connecting line will be broken, thereby affecting the doctor's collection of image data from the patient.

After hanging, the top of the color Doppler probe is attached to the sponge body, avoiding the color Doppler probe from being contaminated due to being exposed. When the color Doppler probe needs to be disinfected and cleaned, the color Doppler probe can be pushed upward, so that the sponge body and the outer sleeve move upward and drive the annular plate, the T-shaped rod and the sealing plate to move upward, so that the disinfectant liquid contained in the material box flows downward through the discharging hole.

Moreover, the second guard plate, the second bending plate and the connecting line are attached to each other, so that the connecting line is clamped. When in use, the connecting line and the color Doppler probe connection part are limited, avoiding the connecting line and the color Doppler probe connection part from being bent. At the same time, the connecting line bending part is limited by the second bending plate, avoiding the connecting line from being excessively bent during stretching, further avoiding damage. When the protective sleeve needs to be replaced, the protective sleeve can be opened through the through slot, then the bending spring piece is pressed down and removed from the clamping groove, and then the bending spring piece and the clamping groove are away from each other, so that the first arc-shaped plate and the second arc-shaped plate are away from each other, the connecting block is squeezed and removed from the color Doppler probe, and the protective sleeve is stretched, so that the first bending plate is separated from the second clamping groove, and the second bending plate is separated from the first clamping groove. The new protective sleeve can be replaced and installed on the color Doppler probe and the connecting line, thereby improving the comfort of the doctor holding the color Doppler probe, and strengthening the protection of the color Doppler probe shell, the color Doppler probe and the connecting line connection part, avoiding damage caused by collision and collision, avoiding wear of the color Doppler probe shell caused by directly holding the color Doppler probe, avoiding breaking of the color Doppler probe and the connecting line connection part caused by bending, further avoiding affecting the image data collection work, and improving the service life of the color Doppler probe.

When the color Doppler probe needs to be disinfected and cleaned, the color Doppler probe can be pushed upward, so that the sponge body and the outer sleeve move upward and drive the annular plate, the T-shaped rod and the sealing plate to move upward, so that the disinfectant liquid contained in the material box flows downward through the discharging hole.
