Description

Technical Field

[0001] This utility model relates to a medical auxiliary device, and more particularly to an ultrasonic coupling agent application device. Background Technology

[0002] Manually applying coupling agent to the ultrasound probe by squeezing the coupling agent container is inefficient.

[0003] Existing technologies have developed mechanisms that automatically extrude coupling agent from a container using mechanical components, thereby improving application efficiency to some extent. Specifically, pressure plates are installed on both sides of the container, driven by a motor-driven screw. By bringing the two pressure plates close together, the container is squeezed, thus extruding the coupling agent. This extrusion mechanism has at least two drawbacks: 1. The pressure plates are approximately rigid bodies. When there is little coupling agent remaining in the container, the pressure plates have difficulty extruding the remaining agent due to their compliant cross-section; 2. The squeezing process of the pressure plates on the container is difficult to synchronize with the application process that generates the probe. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, the present invention provides an ultrasonic coupling agent application device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of this utility model is as follows:

[0006] An ultrasonic coupling agent application device, comprising:

[0007] A cylindrical body, which defines a receiving cavity, and a coupling agent container is disposed in the receiving cavity of the cylindrical body;

[0008] An airbag is disposed in the accommodating cavity of the cylinder and located on the periphery of the coupling agent canister;

[0009] An air pump, located outside the cylinder, supplies air to the airbag through an air pipe connected to the air inlet of the airbag, so that the airbag expands and squeezes the coupling agent canister to squeeze the coupling agent out of the mouth of the coupling agent canister.

[0010] The feed tube has its proximal end connected to the nozzle of the coupling agent tank, and its distal end passes through the medical table and is flush with the table surface. The coupling agent squeezed out from the coupling agent tank flows out from the distal end of the feed tube through the feed tube.

[0011] Preferably, the distal port of the feed tube is configured as a duckbill port.

[0012] Preferably, a one-way valve is installed on the air tube, which only allows fluid to flow from the air pump to the airbag and blocks it from flowing in the reverse direction.

[0013] Preferably, the cylinder includes an open upper cylinder body and a cover detachably fastened to the cylinder body, the cover having a central hole in the middle, and the nozzle of the coupling agent can passing through the central hole.

[0014] Preferably, the medical station is equipped with a visual sensor, the probe of which faces upward and is located on one side of the distal port of the drainage tube. The visual sensor is used to detect whether the ultrasound probe is close to the distal port of the drainage tube. If it is close, the airbag squeezes the coupling agent container; if it is far away, the squeezing of the coupling agent container stops.

[0015] Preferably, an electromagnetic switch valve is installed at the exhaust port of the airbag.

[0016] Compared with the prior art, the beneficial effects of the ultrasonic coupling agent application device provided in the embodiments of this utility model are:

[0017] 1. Because airbags have better conformability, the utilization rate of coupling agent inside the tank is maximized by squeezing the tank with airbags.

[0018] 2. By setting up a vision sensor, the extrusion process of the coupling agent is synchronized with the coating process required by the probe to a higher degree. Attached Figure Description

[0027] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0028] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention discloses an ultrasonic coupling agent application device, which includes: a cylinder 10, an air bladder 20, an air pump 30, an air tube 31, a material guide tube 60, and a vision sensor 70.

[0029] The cylinder 10 includes a cylinder body 11 and a cover 12 fastened to the upper end of the cylinder body 11. The cover 12 is detachably fastened to the cylinder body 11, for example, by screwing it on. The cover 12 has a central hole in its center. The cylinder body 11 has a cylindrical receiving cavity inside. A can containing coupling agent 80 can be placed in the cylinder 10 through the upper port of the cylinder body 11. The bottom of the cylinder body 11 supports the can 80. After the can 80 is placed in the cylinder body 11, the cover 12 is fastened to the cylinder body 11 to restrict the vertical movement of the can 80. The nozzle of the can 80 extends out of the cylinder 10 through the central hole of the cover 12, and the nozzle is used to extrude the coupling agent.

[0030] The airbag 20 is disposed in the cylinder 10 and located on the periphery of the tank 80. When the tank 80 is placed, the tank 80 is inserted into the space defined by the airbag 20. The airbag 20 has an air inlet and an air outlet. The air pump 30 is connected to the air inlet of the airbag 20 through the air pipe 31. The air pump 30 supplies air to the airbag 20 through the air pipe 31, thereby inflating the airbag 20. During the inflation process, the inner wall of the airbag 20 squeezes the tank 80 so that the coupling agent flows out from the mouth of the tank 80.

[0031] The feed tube 60 has a proximal end and a distal end. The proximal end of the feed tube 60 is attached to the nozzle of the tank 80, and the distal end of the feed tube 60 passes through the medical table 100 and is basically flush with the table surface of the medical table 100. The port of the distal end of the feed tube 60 is configured as a duckbill port 61, which is used to extrude the material in a sheet-like (layered) state. When the airbag 20 squeezes the tank 80, the coupling agent extruded from the nozzle of the tank 80 flows out through the feed tube 60 and from the duckbill port 61 of the feed tube 60. At this time, the medical personnel hold the ultrasound probe 200 close to the port to catch the coupling agent, and while catching the coupling agent, they can twist the ultrasound probe 200 to make the coupling agent evenly coated on the surface of the ultrasound probe 200.

[0032] In some preferred embodiments, a one-way valve 40 is installed on the air tube 31. This one-way valve 40 only allows airflow from the air pump 30 to the airbag 20, while restricting the flow of gas from the airbag 20 to the air pump 30. Thus, after each extrusion of the coupling agent by air supply from the air pump 30, the airbag 20 remains in an inflated state, preventing it from re-inflating during the next extrusion. In some more preferred embodiments, an electromagnetic switch valve 50 is installed at the vent port of the airbag 20. After the coupling agent in the canister 80 is used up, the electromagnetic switch valve 50 opens the vent port, thereby deflating the airbag 20 to facilitate the insertion of a new canister 80 into the airbag 20.

[0033] In some preferred embodiments, the medical station 100 is equipped with a visual sensor 70. The probe of the visual sensor 70 faces upward and is located on one side of the distal port of the drainage tube. The visual sensor 70 is used to detect whether the ultrasound probe 200 is close to the distal port of the drainage tube. When the visual sensor 70 detects the ultrasound probe 200, it indicates that the ultrasound probe 200 needs to be coated with coupling agent. At this time, based on control, the air pump 30 supplies air to the airbag 20 to squeeze the canister 80, causing the duckbill port 61 to expel the coupling agent. When the visual sensor 70 does not detect the ultrasound probe 200, it indicates that the ultrasound probe 200 has left the duckbill port 61, thereby controlling the air pump 30 to stop supplying air and stop squeezing the canister 80, thereby causing the duckbill port 61 to stop expelling the coupling agent.

[0034] The advantages of the applicator disclosed in this utility model are:

[0035] 1. Because the airbag 20 has better conformability, the utilization rate of the coupling agent in the tank 80 is maximized by using the airbag 20 to compress the tank 80.

[0036] 2. By setting up a vision sensor 70, the extrusion process of the coupling agent is synchronized with the coating process required by the probe to a higher degree.
