Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, in particular to an automatic induction contactless coupling agent extrusion device. Background Art

[0002] Medical coupling agent is a substance composed of water-based polymer gel, which is used to remove air during the detection and diagnosis process, help the ultrasonic probe to contact with human skin, and improve image quality. As part of medical equipment, medical coupling agent needs to meet the safety and effectiveness standards set by the state. At the beginning of the ultrasound examination, a certain amount of coupling agent needs to be applied to the patient or the probe. The existing coupling agent has a cylindrical pointed bottle body. The front cap needs to be opened and the bottle body squeezed to squeeze the coupling agent onto the patient's body or the probe acoustic lens.

[0003] Because the coupling agent is in a gel state, it needs to be squeezed hard or even shaken to squeeze out quickly. During the operation, it was found that the coupling agent bottle mouth would hit the probe acoustic lens, causing damage to the probe. On the other hand, ultrasound examinations are in great demand in tertiary advanced hospitals. If cumbersome operations are added when using the coupling agent, it will add more burdens to the users. Most of the coupling agent extrusion equipment on the market is either too large or cumbersome to operate, and cannot meet the existing ultrasound examination requirements. Utility Model Content

The controller 14 is electrically connected to the infrared sensor 13 , and the controller 14 is electrically connected to the motor 41 .

[0031] When the device is used to extrude the coupling agent, the coupling agent bottle is inserted into the insert ring 12, and the bottle mouth of the coupling agent bottle is inserted into the inlet of the silicone airbag 8. Before use, the coupling agent is squeezed to fill the chamber 801. The infrared sensor 13 is used to detect the presence of the probe.
