Description

Oral expansion and examination device for pediatric use

Technical field

The present invention relates to an inspection device, in particular to a pediatric oral cavity expansion inspection device.

Background technique

The oral cavity refers to the cavity in the mouth and is the starting part of the digestive tract. It is composed of two lips, two cheeks, hard palate, soft palate, etc. There are organs such as teeth, tongue, and salivary glands in the oral cavity. The front wall of the mouth is the lip, the side walls are the cheeks, the roof is the palate, and the floor of the mouth is the mucous membrane and muscles. The oral cavity is divided into the vestibule of the anterolateral part and the proper oral cavity of the posterior and medial parts by the upper and lower dental arches; when the upper and lower teeth are occluding, the vestibule and the proper oral cavity can be connected through the gap behind the third molar. Clinically, when the patient has trismus, a mouth opener or intubation can be placed through this channel to inject drugs or nutrients while preventing tongue bite. When examining the mouth, the mouth needs to be opened.

Detailed ways

The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

Example 1

A pediatric oral distraction inspection device, as shown in Figure 1-3, includes a mounting plate 1, a distraction component and a tongue depressor component. A distraction component that rotates to perform oral distraction is installed on the left side of the installation plate 1 , a tongue depressing assembly that depresses the tongue by rotating is installed on the top of the mounting plate 1.

As shown in Figure 1-3, the expansion assembly includes a lower bite plate 2, a concave rod 3, an upper bite plate 4, a first nut 5 and a first bolt 6. A lower bite plate 2 is welded to the left side of the installation plate 1. A concave rod 3 is welded between the front and rear sides of the left part of the installation plate 1. The upper part of the concave rod 3 is slidably provided with an upper bite plate 4. A first nut 5 is installed on the right part of the upper bite plate 4. The concave rod 3 is in the middle of the top. The rotary type is provided with a first bolt 6, and the first bolt 6 is connected to the first nut 5 through threads.

As shown in Figures 1 and 2, the tongue depressor assembly includes a tongue depressor 7, a first spring 8 and a second spring 9. The tongue depressor 7 is rotatably installed on the left side of the top of the installation plate 1, and is connected to the left side of the top of the installation plate 1. There is a first spring 8, and a second spring 9 is connected in the middle of the top of the mounting plate 1. The tops of the first spring 8 and the second spring 9 are in contact with the bottom of the tongue depressor 7.

The working principle of the above embodiment: when the device needs to be used to expand and inspect the child's oral cavity, the child's oral cavity is first expanded through the expansion assembly, and then the child's tongue is pressed through the tongue depressor assembly, and then the observation can be started. . After observation, the child's mouth is released by the spreading assembly and the device can be removed.

When the device needs to be used to open the child's mouth, first place the device on the child's mouth so that the child's upper teeth bite on the upper bite plate 4 and the child's lower teeth bite on the lower bite plate 2, and then turn the second One bolt 6 drives the upper bite plate 4 to move upward to open the child's mouth. When the device needs to be loosened, the first bolt 6 can be reversed to drive the upper bite plate 4 to move downward so that the child's mouth is no longer open. be propped open and the device can then be removed. By changing the position of the upper bite plate 4, the opening size of the oral cavity can be changed, which facilitates the doctor's observation.

When the doctor is observing, first press the tongue depressor 7 to a horizontal state, compress the first spring 8 and the second spring 9, and then slowly release the right side of the tongue depressor 7, and slowly release the first spring 8 and the second spring 9. Reset, drive the left side of the tongue depressor 7 to swing downward to press down the child's tongue. In this way, the child's tongue can be pressed down conveniently and quickly, making it convenient for the user to use the device.
