Description

[Detailed Description of the Invention] The present invention relates to a tongue depressor suitable for use in autopsy of the pharynx, larynx, etc.

When doctors examine the inner parts of the oral cavity, such as the pharynx and larynx, they traditionally operate a metal tongue depressor with one hand.
He was using a flashlight held in one hand to illuminate the inside of his mouth.

However, when using such a method, not only do you have to use both hands, but you also have to hold a flashlight close to your mouth, so you have to look into the oral cavity from the side of the light, and as a result, the pharynx, Not only does autopsy of the larynx require a considerable amount of effort, but it is also inconvenient because it is difficult to see the affected area clearly.

Therefore, in order to solve the above-mentioned conventional difficulties,
As shown in Figure 1, a holder 2 with a built-in light source 10
A tongue holding piece 30 made of a light transmission material such as plastic is attached to the tip of the tongue.

However, in this case, the light beam entering the tongue presser piece 30 from the light source 10 is irradiated forward from the light emitting surface 30a formed at the tip of the tongue presser piece 30. When inserted into the mouth and pressed down on the tongue, the light emitting surface 30a is in a position close to the pharynx, and as a result, only a small part of the pharynx etc. is irradiated with the forward emitted light, and it covers a wide range. In order to irradiate the patient, the tongue presser piece 30 must be pulled toward the user, which makes it impossible to press the tongue down sufficiently, making it impossible to expect satisfactory results from the medical examination.

Therefore, the present invention attempts to solve the above-mentioned conventional difficulties by appropriately forming the shape of the tongue presser piece and providing a light emitting surface at the appropriate location.
The present invention will be explained below based on the illustrated embodiments.

The tongue depressor according to the present invention, as shown in FIG.
This is the same as the conventional example in that the holder 2 includes a light source 3 inside.

However, in the present invention, as shown in FIG.
A concavely curved tongue pressing surface 1d is formed by the lower surfaces of both parts 1b and 1c, and the proximal thick part 1
The upper surface 1b' of b and the upper surface 1c' of the tip-side thin portion 1c formed in a step-like manner are connected to each other by a light emitting surface 1e.

Although the illustrated light emitting surface 1e is formed approximately perpendicularly to the tongue-pressing surface 1d, it may also be formed obliquely.

In addition, in the holder 2 shown above, a dry battery (not shown) is housed in a cylindrical case, and a light source 3 can be turned on by this, and the light from the light source 3 is transmitted from the end surface 1a' of the light input protrusion 1a. It is configured to enter into the tongue presser piece 1.

Therefore, if this is used in the usual way, the light from the light source 3 will enter from the light input protrusion 1a and enter the tongue presser piece 1, and the incident light will be directed to the upper surface of the proximal thick part 1b, as is known. , the light is not emitted through repeated total reflection on the lower surface, but is emitted forward from the light emitting surface 1e.
The pharyngeal region is irradiated over a fairly wide range by the radiation from the light emitting surface 1e, which is spaced from the pharynx by a length of .

As described above, the present invention consists of a holder equipped with a light source and a tongue presser piece made of a light transmission member attached to the holder, and the light from the light source is incident on the proximal end of the tongue presser piece. In the tongue depressor which emits light rays forward from a light emitting surface formed on the distal end side of the tongue depressor, the tongue depressor 1 is formed of a thick walled part 1b on the proximal end side and a thin walled part 1c on the distal end side. , the lower surfaces of both the thick portions 1b and 1c are used as the tongue-pressing surface 1d, and the upper surface of the proximal thick portion 1b and the upper surface of the distal thin portion 1c formed in a step shape from the upper surface are exposed to light. Since the light emitting surface 1e is connected to the light emitting surface 1e, the light beam can be sufficiently diffused even when the tongue presser piece 1 is placed at an appropriate position between the light emitting surface 1e that emits light and the pharynx. Therefore, the pharynx will be brightly illuminated over a wide area.

Furthermore, in the present invention, since the tip-side thin portion 1c extends to the tip side of the light emitting surface 1e, a part of the light emitted from the light emitting surface 1e is transmitted to the thin portion 1c.
Since the light reflected by the upper surface of the tongue depressor can participate in the irradiation of the pharynx, etc., the illuminance of the area to be examined is increased accordingly, making it possible to provide a tongue depressor that is extremely easy to use. .
