Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oral examination tool that collects and tests saliva to check for advanced diseases appearing in the oral environment, oral cavity, and saliva.

[Conventional technology] It is already known to check the oral environment, bad breath, alveolar cavities, gingivitis, and other oral diseases by testing the pH of saliva, glucose, lactic acid, blood, etc. in saliva. For example, Showa Yakuhin Kako Co., Ltd.'s "Saribuster" (registered trademark), "RD Test Showa",
Toyo Roshi Co., Ltd.'s tobacco test paper, Sunstar Co., Ltd.'s "Ion, Balance Tester" (the above)
Test strips such as (trade name) are commercially available.
Tests of the oral environment, etc. using these test strips can be carried out by licking the test strip directly, spitting saliva on the test strip, dropping saliva collected in a container onto the test strip using a dropper, or collecting saliva in a container. This is done by soaking a test strip in saliva.

However, although licking the test strip directly has the advantage that saliva collection and testing are easy, the color quality of the test strip changes due to direct licking of the test strip containing the reagent and contact with saliva. Not only is there a great sense of resistance due to this, but there is also a large variation in the amount of saliva that adheres to the test strip, and depending on the reagent, it is not desirable to lick it.

On the other hand, spitting saliva onto the test strip tends to stain the surrounding area, and dropping saliva collected in a container onto the test strip or dipping the test strip into saliva requires other equipment. Not only that, but it is also troublesome to operate.

[Problems to be solved by the invention] The problems to be solved by the invention are to obtain an oral testing device that not only allows saliva to be easily collected regardless of the type of reagent used, but also is easy to operate. It is something to do.

[Means for Solving the Problems] The oral examination tool of the present invention has a support formed by two thin plate-like support pieces arranged in a V-shape in the same plane, and the tip of one support piece. A testing element containing an oral reagent is provided in one part, and a saliva collection part for collecting saliva by direct contact with the oral cavity is formed at the tip of the other support piece, and the support is attached to the middle part of the V-shape. The present invention is characterized in that the test element and the saliva sampling portion of both support pieces can be folded into a state where they overlap with each other.

[Operation] With the support completely opened so that the two support pieces are located in the same plane, by bringing the saliva collection part of one support piece into contact with the appropriate location in the oral cavity,
Collect saliva. At this time, when the support piece with the saliva collection part is placed parallel to the lips and its tip is directed toward you, the other support piece with the test element is automatically positioned with the tip facing toward the side of your face. Therefore, the support piece does not get in the way of saliva collection.

In addition, since the above-mentioned saliva collection is performed using a saliva collection part separate from the test element, there is not only no danger or resistance of the test element containing the reagent coming into direct or indirect contact with the oral cavity; Saliva can be safely collected regardless of the type of reagent used.

After collecting saliva, when the support is bent, the saliva collection part and the test element overlap and the saliva adheres to the test element, so the oral environment and oral diseases can be checked using the reagent contained in the test element. Can be done.
Therefore, it is easy to operate and does not require any special equipment for inspection.

[Example] Fig. 1 shows an example of the present invention, and the oral cavity testing device of this example has two thin plate-like support pieces 1a and 1b connected in a V-shape in the same plane. A saliva collection method in which a test element 2 containing an oral cavity reagent is attached to one support piece 1a of a support body 1 having a shape, and saliva is collected by directly contacting a part of the oral cavity to the other support piece 1b. The support body 1 can be folded into a state in which the test element 2 and the saliva collection part 3 overlap each other at the middle part of the V-shape.

The support 1 is made of a thin sheet of synthetic resin such as polyethylene, polyester, or vinyl chloride, an elastic body such as a thin metal sheet, or a thin, shape-retaining, and bendable material such as paper or synthetic paper. A fold line or bent portion 4 is provided approximately at the center in the longitudinal direction to facilitate bending.

The test element 2 detects one or more of saliva's PH, glucose, nitrous acid, mercaptan, amino acids, lactic acid, blood, oxygen, etc. in saliva through color development and changes in color quality due to the adhesion of saliva. This is used to check the oral environment and oral diseases such as bad breath, alveolar cavities, and gingivitis, and is made of paper or multilayer film containing desired reagents for detecting these.

The saliva collection section 3 is made of an appropriate material that can collect saliva by contact with the oral cavity, such as filter paper, foam, sintered body, nonwoven fabric, or textile.
If debris remains in the oral cavity due to saliva collection, it may cause discomfort, so a material from which debris does not easily fall off when in contact with the oral cavity is preferable.

Therefore, the test element 2 and saliva collection section 3 are as follows:
They are provided on the same surface of the support 1 at approximately the same distance from the fold line 4 of the support 1 .

The oral cavity testing device of the above embodiment allows saliva to be easily collected without using other instruments such as containers by gripping the support 1 and bringing the saliva collection part 3 into contact with an appropriate location in the oral cavity such as the tongue. Furthermore, unlike when saliva is directly collected with a test element containing a reagent, there is no change in the color quality of the test element 2, which not only eliminates the reluctance to collect saliva, but also eliminates the reluctance to collect saliva. Reagents may also be used that are best avoided in direct contact with the oral cavity.

After collecting saliva, when the support 1 is bent along the fold line 4, the test element 2 and the saliva collection part 3 overlap and the saliva adheres to the test element 2. You can check etc. Therefore, saliva testing is extremely simple, and since both the testing element 2 and the saliva collecting part 3 are attached to the support 1, there is no need to worry about losing one or the other and replenishing it.

Furthermore, saliva can be heated by stacking the test element 2 and the saliva collection part 3 and pressing them down with your fingers, and by changing the thickness and material of the saliva collection part, the amount of saliva to be collected can be controlled, making it possible to conduct tests. Accuracy can be increased.

[Effects of the invention] As described above, according to the invention, in an oral testing device of the type that tests saliva by bringing it into direct contact with the oral cavity, a testing element containing a reagent and a saliva collection part for collecting saliva are combined. The saliva collection part is provided separately and brought into contact with the oral cavity to collect saliva, which is then attached to the test element and reacted with, so that the test element containing the reagent does not come into contact with the oral cavity directly or indirectly. Therefore, regardless of the type of reagent used, saliva testing can be performed safely and without any resistance.

In addition, when collecting saliva with the saliva collection section, the two support pieces should be opened and one of the support pieces equipped with the saliva collection section should be parallel to the lips with its tip facing toward you. However, at this time, the tip of the other support piece equipped with the test element automatically points toward the side of the face, so the support piece protrudes in front of the eyes and nose and becomes an eyesore. Saliva collection can be easily and smoothly performed without touching the face or interfering with the collection process.

Furthermore, since the two support pieces are arranged in a V-shape and bent in two at the middle of the V-shape,
Compared to the case where support pieces of the same length are arranged in a straight line and bent at an intermediate position, the displacement distance of the two support pieces when the support body is folded from a completely open state, that is, the distance between the test element and the saliva. It is possible to reduce the distance that the sample parts move before they overlap with each other, which has the advantage that the bending operation is easy and it is easy to handle.
