Description

mouth mirror for self-examination

technical field

The utility model relates to a mouth mirror for oral examination.

Background technique

Ordinary people usually observe the oral cavity through the reflection of the mouth mirror during the daily oral health self-examination. Due to the problem of the intensity and angle of light irradiation and the anatomical shape of the oral cavity, it is impossible to clearly and intuitively observe the conditions of the various anatomical structures in the oral cavity and ignore the oral cavity. Therefore, these problems cannot be discovered and solved in time, which delays the timing of treatment.

Contents of the invention

In view of the above-mentioned problems, the main purpose of this utility model is to provide a convenient tool for oral self-examination for ordinary people, so that ordinary people can better understand their own oral conditions and do a good job in oral self-care.

The utility model is a mouth mirror for self-inspection, which is composed of an eyepiece 1, an extended optical fiber 2, a mirror handle 3 and a mirror base 5. There are a first light source 6, a wide-angle objective lens 7 and a second light source 8 on the mirror base 5. The switch 4 for controlling the first light source 6 and the second light source 8 is installed on the mirror handle 3, and the button battery for supplying power to the first light source 6 and the second light source 8; Two light source 8, the lead wire of switch 4 and battery; Extended optical fiber 2 passes mouth mirror handle 3, and one end of extended optical fiber 2 connects wide-angle objective lens 7, and the other end connects eyepiece 1.

The beneficial effect of the utility model is: the mouth mirror for self-examination uses the objective lens to image the observation part inside the oral cavity, and transmits the imaged image to the eyepiece outside the oral cavity through the optical fiber, and the observer can directly observe the observation inside the oral cavity through the eyepiece. parts. It provides a convenient and practical inspection tool for the general population to carry out self-examination of oral hygiene.

Detailed ways

The detailed content and technical description of the present utility model are further described with examples, but it should be understood that the following examples are only for illustrative purposes, and should not be construed as limitations to the implementation of the present utility model.

As shown in Figure 1, the utility model is a mouth mirror for self-examination, which is composed of an eyepiece 1, an extended optical fiber 2, a mirror handle 3 and a mirror base 5, and a first light source 6, a wide-angle objective lens 7 and a mirror base 5 are arranged on the mirror base 5. The second light source 8, a switch 4 for controlling the first light source 6 and the second light source 8, and a button battery for powering the first light source 6 and the second light source 8 are installed on the mirror handle 3; The lead of first light source 6, second light source 8, switch 4 and battery; Extended optical fiber 2 passes mouth mirror handle 3, and one end of extended optical fiber 2 connects wide-angle objective lens 7, and the other end connects eyepiece 1. The light reflected by the position to be observed is imaged at the end of the extended optical fiber 2 connected with the wide-angle objective lens 7 through the wide-angle objective lens 7, and the image is transmitted to the end of the optical fiber connected with the eyepiece 1 through the optical fiber, and is amplified in the eyepiece 1. Easy to observe.

As shown in FIG. 1 , the wide-angle objective lens 7 , the first light source 6 and the second light source 8 are located on the mounting surface on the same side of the mirror base 5 .

As shown in Figure 2, the value range of the angle α between the first geometric axis QQ′ of the mirror handle 3 and the second geometric axis PP′ of the mirror base 5 is: 30°<α<90° .

As shown in Figure 3, it is the first embodiment of the utility model, and the A-A cross section of the mouth mirror base 5 is a square.

As shown in FIG. 4 , the B-B cross section of the mirror handle 3 is a circular ring.

As shown in Figure 5, which is the second embodiment of the present invention, the A-A cross section of the mouth mirror base 5 is hexagonal, or rectangular, or polygonal with 5 to 8 sides. Here both will take into account the comfort of mouth mirror base 5 in user's oral cavity, will also consider the stability of placing in mouth mirror base 5 oral cavity again, also will guarantee to be wide-angle objective lens 7, the first light source 6 and the second light source simultaneously. The light source 8 provides a sufficient mounting surface.

The first light source 6 and the second light source 8 adopt LED lamp beads.

The switch 4 is a rotary button for controlling the brightness of the first light source 6 and the second light source 8 .

As shown in FIG. 6 , the port mirror handle 3 is directly connected to the port mirror base 5 , or is hinged through a hinge shaft 5 ′, or is connected through a universal joint.

As shown in Figure 7, the specific self-inspection process is: the examiner holds the mouth mirror handle 3, puts one end of the mouth mirror base 5 into the oral cavity, turns on the light source switch 4, observes and adjusts in the eyepiece 1, and aligns the wide-angle objective lens 7 with the eyepiece. The part to be observed, the light reflected by the part to be observed is imaged at the end of the extended optical fiber 2 connected to the wide-angle objective 7 through the wide-angle objective lens 7, and the image is transmitted to the end of the optical fiber connected to the eyepiece 1 through the optical fiber. The eyepiece 1 can observe a clear image of the observed part, which is helpful for timely detection of oral health problems and immediate intervention and treatment.
