Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic examination, and in particular relates to an auxiliary device for ultrasonic examination. Background Art

[0002] Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality and strong penetrating ability. With the development of current medical level, ultrasound has been maturely applied in medical examinations. Coupling agent is needed in the examination process, but the current coupling agents are all independent open structures, and medical staff need to apply them manually when using them.

[0003] Manual application is not only inefficient, but also after application, medical staff need to clean the coupling agent on their hands before they can operate ultrasound to examine the patient, which is very time-consuming and will also cause a waste of coupling agent. Chinese patent application number 202111405131.4 discloses an auxiliary device for ultrasonic examination, which uses an application roller to apply the coupling agent. Due to the limitation of the length of the application roller, when the application roller is designed to be too long, it can be applied over a large range. However, due to the limitation of the diameter of the discharge pipe port, it is easy to cause uneven application of the coupling agent. If the paint tube and the application roller are set horizontally and multiple openings are opened on the side of the application tube, although the application range of the coupling agent can be controlled, as the coupling agent is discharged, the pressure in the application tube gradually decreases, resulting in different amounts of coupling agent sprayed from openings at different positions of the application tube. When the length of the application roller is set too short, although it can ensure that the coupling agent is evenly applied, it will cause the application range to be too small and the application efficiency to decrease.
