Description

Technical Field

[0001] The present invention relates to the technical field of coupling agent coating, in particular to a coupling agent coating device for ultrasonic diagnosis. Background Art

[0002] Ultrasound examination is an important method for disease diagnosis and plays an important role in clinical diagnosis and physical examination. During color Doppler ultrasound examination, medical staff will hold the color Doppler ultrasound probe and move it over the patient's body part to be examined, and examine the patient from different angles. The coupling agent is applied to the patient's skin during ultrasound examination. Its function is to fill the gaps between the contact surfaces to avoid the presence of particles in the gaps that affect the penetration of ultrasound, reduce the acoustic impedance between the probe and the skin, and reduce the friction resistance between the probe surface and the skin.

[0003] Before the existing color Doppler ultrasound examination, the coupling agent needs to be squeezed manually onto the patient's body, and then the color Doppler ultrasound probe drives the coupling agent to be evenly applied to the patient's body during the examination. This operation method, on the one hand, is not convenient for controlling the amount of coupling agent squeezed out. Excessive squeezing will cause waste of coupling agent, and too little squeezing will increase the acoustic impedance between the probe and the skin, affecting the color Doppler ultrasound examination. On the other hand, a ball of coupling agent is squeezed out of the patient's body in advance, and the color Doppler ultrasound probe is used to drive the coupling agent to be evenly applied to the patient's body, so that some parts of the patient's body that do not need to be examined are also coated with coupling agent (for example, to examine the patient's kidneys), resulting in a large coating area, which makes it troublesome for the patient to wipe it off after the examination is completed. At the same time, it is also easy to dirty the patient's clothes. For this reason, we propose a coupling agent coating device for ultrasonic diagnosis to solve the above problems.
