A method for using a pediatric internal medicine detection device comprises the following steps:

S1. When using the pediatric internal medicine detection device, first pull the pull rope to move the U-shaped adjustment sleeve toward the compression spring to the limit position. During this process, the one-way tooth plate will not rotate with the gear rod. Then, the spring plug rods on both sides of the U-shaped adjustment sleeve contact the wedge block and release the plug from the one-way tooth plate. Then, release the pull rope to put the tongue depressor shell into the patient's mouth and detect it through the micro camera.

S2. After the pull rope is released, the compression spring presses the U-shaped adjustment sleeve to reset and move. At the same time, under the action of the guide spring, the one-way tooth plate resets and moves and meshes with the gear rod. When the gear rod rotates with the top adjustment disk and the pin shaft, the pin shaft slides along the special-shaped guide groove track at the bottom of the double-head plug disk, so that the double-head plug disk moves back and forth between the two sliding sleeves. Under the cooperation of the slots staggered on both sides of the U-shaped adjustment sleeve and the double-head plug disk, the U-shaped adjustment sleeve moves toward the front end direction of the tongue depressor housing in stages.

During the staged movement of the U-shaped adjustment sleeve, the main one-way tooth plate on the left side of the U-shaped adjustment sleeve is meshed with the transmission gear in stages, so that the transmission gear drives the transmission gear rod to mesh with the pulling tooth plate for transmission. Then, during the movement of the pulling tooth plate, the pulling bar and the rotating rod are pulled by the pulling shaft to rotate inside the main fan-shaped groove, and the swing bar on the top of the rotating rod moves along the trajectory of the surface of the micro camera with the arc scraper to clean up the adhered saliva;

S4. When the main one-way tooth plate is disengaged from the transmission gear, the pulling spring presses the pulling tooth plate to reset, so that the pulling tooth plate, the pulling bar, the rotating rod, the swing bar and the arc scraper reset and swing. As the main one-way tooth plate is periodically engaged with the transmission gear, the arc scraper periodically cleans the surface of the micro camera. When the arc scraper swings left and right to the extreme position, the surface of the arc scraper contacts the arc cleaning plate at the front end of the tongue depressor shell, and foreign matter adhering to the arc scraper is cleaned away.

Compared with the prior art, the present invention has the following beneficial effects:

In the present invention, through the coordinated use of components such as the tongue depressor shell, the cleaning mechanism and the micro camera, when the user uses the tongue depressor shell and the micro camera to detect the inside of the patient's mouth, the cleaning mechanism can scrape off saliva on the surface of the micro camera through the arc scraper, thereby preventing the saliva from affecting the shooting effect of the micro camera and improving the detection effect.

In the present invention, through the coordinated use of components such as the tongue depressor shell, the adjustment mechanism and the cleaning mechanism, by pulling the pull rope on the adjustment mechanism before inspecting the patient's oral cavity, during the process of the tongue depressor shell conducting internal oral inspection, the adjustment mechanism can automatically and periodically operate the cleaning mechanism to regularly clean the micro camera, thereby avoiding the need for multiple manual adjustments and cleanings during the inspection process, thereby improving ease of use.

In the present invention, through the coordinated use of components such as the micro camera, the arc scraper and the arc cleaning plate, when the arc scraper moves back and forth on the surface of the micro camera for cleaning, if foreign matter remains on the surface of the arc scraper, when the arc scraper moves to the position of the arc cleaning plate, the arc cleaning plate can clean the surface of the arc scraper, thereby improving the scraping effect of the arc scraper and preventing foreign matter from adhering to the surface of the micro camera as the arc scraper moves.
