In addition, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] Such as Figure 1 and Figure 2As shown in the figure, the automatic coupling agent extrusion device of the embodiment of the present utility model includes a housing 1, a suction valve 2, an extrusion valve 3, a flexible electric heating film 4, an electric extrusion block 5, an infrared sensor 6 and a main controller 7. The suction valve 2 and the extrusion valve 3 are both arranged inside the housing 1, and a flexible chamber 8 for storing the coupling agent is formed between the suction valve 2 and the extrusion valve 3. An installation port for installing a coupling agent bottle 9 is provided at the upper end of the housing 1, and the coupling agent bottle 9 can be detachably connected to the suction valve 2. A probe placement port 10 is provided at the lower end of the housing 1. The nozzle of the extrusion valve 3 is arranged facing the probe placement port 10, and the infrared sensor 6 is arranged at the probe placement port 10 so that when the ultrasonic probe extends into the probe placement port 10, automatic induction can be achieved through the infrared sensor 6. The flexible electric heating film 4 is wrapped outside the flexible chamber 8, and the electric extrusion block 5 is arranged inside the housing 1 at a position corresponding to the flexible chamber 8. The electric extrusion block 5 is used to control the compression and release of the flexible chamber 8. The main controller 7 is arranged outside the housing 1, and the main controller 7 is electrically connected to the flexible electric heating film 4, the electric extrusion block 5 and the infrared sensor 6 respectively.

[0024] When in use, first install the coupling agent bottle 9 at the installation port and make a reliable connection with the suction valve 2. When the ultrasonic probe extends into the probe placement port 10, automatic induction can be achieved through the infrared sensor 6 and the induction signal is transmitted to the main controller 7. The main controller 7 controls the electric extrusion block 5 to work, applies a certain force to the flexible chamber 8, and thus controls the compression and release of the flexible chamber 8. Since both the suction valve 2 and the extrusion valve 3 are one-way valves, and the nozzle of the suction valve 2 is arranged facing the flexible chamber 8, when the flexible chamber 8 is compressed, under the action of the internal air pressure in the flexible chamber 8, the suction valve 2 closes and the extrusion valve 3 opens, so as to extrude the coupling agent in the flexible chamber 8. When the flexible chamber 8 is released, the suction valve 2 opens and the extrusion valve 3 closes, so as to suck the coupling agent in the coupling agent bottle 9 into the flexible chamber 8. When the environment is cold in winter, the main controller 7 can be used to control the flexible electric heating film 4 to work for preheating the coupling agent in the flexible chamber 8.

[0025] Therefore, the automatic coupling agent extrusion device of the embodiment of the present utility model can realize the automatic induction extrusion of the coupling agent, replaces the original manual extrusion operation, is more convenient to use, and does not need to directly contact the coupling agent during use, which can prevent cross-infection caused by contact with the coupling agent when used among different patients. In addition, when it is cold, the coupling agent can be preheated. The preheated coupling agent contacts the patient through the ultrasonic probe, which can greatly improve the comfort of the patient.

[0026] Specifically, both the inhalation valve 2 and the extrusion valve 3 are made of silicone material, and the one-way conduction function of the inhalation valve 2 and the extrusion valve 3 can be realized through the internal and external pressure difference. The structures of the inhalation valve 2, the extrusion valve 3 and the flexible chamber 8 adopt the existing structural forms, so no specific description will be made here. For example, the structural forms of the inhalation valve, the extrusion valve and the working chamber in the automatic toothpaste extruder with the publication number CN201595756U can be adopted, or the structural forms of the inhalation valve, the extrusion valve and the working chamber in the automatic toothpaste extruder with the publication number CN206087606U can also be adopted.

[0027] Specifically, the electric extrusion block 5 can use an electric push rod to provide the extrusion driving force, so as to realize the control of the compression and release of the flexible chamber 8.

[0028] In some embodiments of the present utility model, the automatic coupling agent extrusion device further includes a temperature controller (not shown in the figure) electrically connected to the flexible electric heating film 4, and the temperature controller is electrically connected to the main controller 7. The heating temperature of the flexible electric heating film 4 can be adjusted and controlled through the temperature controller, so that the heating temperature of the flexible electric heating film 4 is controlled within a suitable range to ensure the use performance of the coupling agent.

[0029] Specifically, a display screen 11 is provided on the main controller 7, and the display screen 11 is electrically connected to the main controller 7. Through the display screen 11, various working parameters such as the heating temperature of the flexible electric heating film 4 and the extrusion amount of the coupling agent of the extrusion valve 3 can be displayed.

[0030] Among them, a plurality of control buttons 12 are also provided on the main controller 7, and the control buttons 12 are electrically connected to the main controller 7. The control buttons 12 are used to realize the parameter setting and working state control of the automatic coupling agent extrusion device.

[0031] Among them, a gear switch 13 for controlling the extrusion amount of the coupling agent is also provided on the main controller 7, and the gear switch 13 is electrically connected to the main controller 7. That is, the maximum extrusion stroke of the electric extrusion block 5 can be set through the gear switch 13, so as to control the extrusion degree of the flexible chamber 8, and further control the extrusion amount of the coupling agent. For example, three gears can be set to correspond to three different extrusion amounts of the coupling agent, and these three extrusion amounts are small amount, medium amount and large amount respectively. The gear of the extrusion amount of the coupling agent can be preset according to the actual use requirements, so as to automatically extrude the coupling agent as needed during use and avoid waste of the coupling agent.

[0032] In some embodiments of the present utility model, a hook 14 is also fixedly provided on the upper end of the outer side of the housing 1, which is convenient for hanging and installing the automatic coupling agent extrusion device on the ultrasonic examination equipment.

[0033] Specifically, the housing 1 can be made of a transparent material, which is convenient for observing the amount of the coupling agent in the coupling agent bottle 9 and the extrusion of the coupling agent on the ultrasonic probe.

[0034] In some embodiments of the present invention, the coupling agent automatic extrusion device further includes a power cord (not shown in the figure), and the power cord is electrically connected to the main controller 7. Through the power cord, it can be connected to an external power source, so as to provide electrical energy for the operation of the coupling agent automatic extrusion device.

That is to say, the storage battery 15 can also be provided to supply electrical energy for the coupling agent automatic extrusion device.
