Because they are cheaper than CT and MRI, and are non-invasive and can obtain real-time images of tissues in the human body, their clinical application range is becoming more and more extensive.

[0003] At present, when using medical ultrasonic diagnostic equipment, medical staff usually need to squeeze the coupling agent onto the skin of the person being examined, then apply the coupling agent squeezed onto the skin, and finally, hold the ultrasonic probe to detect the skin applied with the coupling agent. This traditional coupling agent application method wastes a lot of time for operators, especially when applying by squeezing, medical staff will feel the dosage of the coupling agent, and there will be problems of squeezing too much or too little. Squeezing too much will cause waste of coupling agent, and squeezing too little will interrupt the operation process of ultrasound, which brings great inconvenience to the inspection and treatment work of operators.

DETAILED DESCRIPTION

[0027] See also Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: an auxiliary structure of an ultrasonic diagnostic instrument, the ultrasonic diagnostic instrument includes an ultrasonic probe 5 for ultrasonic imaging and a liquid storage bottle 6 for containing coupling liquid. The auxiliary structure includes an application component 1, a peristaltic pump 2, a bottle cap 3 and a connecting tube 4 connecting the above three components in series. The bottle cap 3 is installed at the output end of the liquid storage bottle 6 and the connecting tube 4 extends through the bottle cap 3 into the liquid storage bottle 6. The peristaltic pump 2 is arranged on the connecting tube 4, and is used to transport the coupling liquid in the liquid storage bottle 6 to the application component 1. The application component 1 is installed on one side of the ultrasonic probe 5, and is used to control the peristaltic pump 2 and dilute the coupling liquid for uniform application on the patient's body surface.

[0028] In specific work, the output end of the liquid storage bottle 6 is removed, and then the connecting tube 4 is inserted and the output end of the liquid storage bottle 6 is tightened with the bottle cap 3. Then the application component 1 is grasped and the peristaltic pump 2 is started. The peristaltic pump 2 draws out the coupling liquid in the liquid storage bottle 6 and transports it to the application component 1. The application component 1 dilutes the coupling liquid to facilitate medical staff to evenly apply the coupling liquid on the patient.

[0029] The peristaltic pump 2 includes a pump body 21, a roller 22, an extrusion wheel 23 and a receiving chamber 24.

The connecting tube 4 passes through the receiving chamber 24 and is arranged along the cavity surface of the receiving chamber 24 when passing through the receiving chamber 24. When the roller 22 rotates, the extrusion wheel 23 will continuously squeeze and release the connecting tube 4, thereby generating a peristaltic wave. Driven by the peristaltic wave, the coupling liquid in the connecting tube 4 flows toward the direction of the application component 1.

[0030] The coating assembly 1 includes a coating part 11 and a control part 12. The control part 12 is connected to the coating part 11 and is used to control the opening or closing of the peristaltic pump 2.

In specific operation, the peristaltic pump 2 is started by grasping the control part 12, and the coupling liquid is transported to the coating part 11. After passing through the coating part 11, the coupling agent is diluted and squeezed out from the output end.

[0031] The application part 11 includes a main body 111 and a clamping end 112 and an application end 113 connected to the main body 111.

An application end 113 is provided on the other side of the main body 111, and an application groove 1131 is provided on the application end 113 along the length direction. The coupling liquid is diluted through the application groove 1131 so that it flows out evenly. The application end 113 is tilted on the main body 111, and the tilted application end 113 can better adapt to the curve or unevenness of the application surface and improve the application effect.

The application part 11 is easy to operate and maintain as a whole, and the application part 11 is relatively small as a whole, which is convenient for users to operate. In addition, replacing the coupling liquid with a cleaning liquid is also easy to clean and maintain, which can increase the service life of the equipment. The main body 111, the clamping end 112 and the application end 113 adopt an integrated design. Such a design simplifies the structure, reduces the number of parts, and improves the assembly efficiency and product reliability.

[0033] The control unit 12 is composed of two upper and lower shells 123 that are connected to each other. The control unit 12 is provided with a switch 121 that is electrically connected to the peristaltic pump 2. The switch 121 is used to control the peristaltic pump 2 to turn on or off. In this embodiment, the switch 121 is a press switch 121. By pressing the switch 121, the peristaltic pump 2 can be turned on and off.
