Abstract

PROBLEM TO BE SOLVED: To provide a horny layer observation tool capable of easily observing a horny layer. SOLUTION: A window hole 5 is passed through and provided on the left side of a base plate 2 and a background part 6 printed in a dark color is provided on the right side. A transparent film 3 to which an adhesive material is attached is joined to the back surface of the base plate 2 and the window hole 5 is closed. The transparent film 3 is provided with a tongue piece part 8 projected outward from the base plate 2. After sticking the horny layer to the adhesive material stuck to the closing part 10 of the transparent film 3 for closing the window hole 5, the base plate 2 is bent with a bending position 11 as a center and the tongue piece part 8 is joined to the surface 4 of the base plate 2. Thus, by the elasticity of the plate 2, a part where the window hole 5 is present is separated from the part where the background part 6 is present and a space is formed between them.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instrument for observing the stratum corneum of the skin.

[0002]

2. Description of the Related Art Conventionally, as a method for observing a horny layer, a film having an adhesive surface coated with an adhesive is pressed against the skin, the horny layer is peeled off from the skin and adhered to the adhesive surface of the film. A method of directly observing the stratum corneum adhered to the adhesive surface or dyeing the stratum corneum and observing the stratum corneum finely is adopted.

Since the stratum corneum has a whitish color, when directly observing the stratum corneum, a transparent film is used for the film, and a dark background is arranged behind the transparent film having the stratum corneum attached thereto. When viewed, the stratum corneum is easy to observe. Therefore, conventionally, the adhesive surface of the transparent film having the stratum corneum adhered thereto was adhered to a dark background plate and observed.

[0004]

However, in the conventional method, since the adhesive surface of the transparent film is in close contact with the background plate, the horny layer is strongly pressed against the adhesive surface, and as a result, the horny layer is buried in the adhesive surface. There is a problem that the stratum corneum becomes more inconspicuous as time passes, making it difficult to observe and resulting in inaccurate observation results.

[0005] The present invention has been made in view of such problems of the prior art, and has as its object to provide a stratum corneum observation tool that facilitates observation of the stratum corneum.

[0006]

The present invention has the following features to attain the object mentioned above. The stratum corneum observation tool according to the present invention is provided with (a) a substrate having elasticity, (b) a window hole provided in the substrate, and (c) provided on a surface of the substrate at a position separated from the window hole. Dark background and (d)
A transparent film that is bonded to the back surface of the substrate so as to close the window hole, and is a portion corresponding to the window hole and has an adhesive adhered to the front surface side of the substrate; and After attaching the stratum corneum to the material, fold the side where the window hole is present on the substrate to the side where the background part is present, and observe the stratum corneum with the background part as a background through the transparent film. It is characterized by.

Since the substrate has elasticity, even if the side of the substrate where the window is present is folded back to the side where the background is present, the side where the window is present tends to separate from the side where the background is present. As a result, a space is formed between the two, so that the portion of the transparent film to which the adhesive is adhered does not adhere to the background of the substrate. Therefore, the stratum corneum adhered to the adhesive material is not buried in the adhesive material, and can be maintained in a state that is easy to observe for a long time.

[0008] Examples of the substrate include a paper sheet and a plastic sheet. The reason why the background portion is dark is to make it easier to observe the stratum corneum.
Black, dark brown, dark green, dark blue, dark purple etc. can be adopted.

In the case where the transparent film has a tongue piece projecting outward from the substrate, and an adhesive is also attached to the surface of the substrate at the tongue piece, the tongue piece is folded when the substrate is folded. By attaching the portion to the substrate, the folded state having a space therebetween can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the stratum corneum observing tool according to the present invention will be described below with reference to FIGS.

FIG. 1 is a plan view of the stratum corneum observation tool 1 as viewed from the front side, and FIG. 2 is a rear view as viewed from the back side. The stratum corneum observation tool 1 includes a paper substrate 2 and a plastic transparent film 3 bonded to the substrate 2. The substrate 2 has a circular window hole 5 penetrating therethrough on the left side when viewed from the surface 4 thereof, and a background portion 6 formed on the right side. The background portion 6 is a portion where the surface 4 of the substrate 2 is printed in a dark color (for example, black), and has a larger diameter than the window hole 5. The shape of the background portion 6 is not limited to a circle, but may be a square, or the entire surface 4 of the substrate 2 may be printed in dark color to form the background portion 6.

The transparent film 3 has a large circular portion 7 for closing the window 5 of the substrate 2 and a tongue 8 protruding outward from the left end of the substrate 2. An adhesive is attached to the entire surface of the transparent film 3, and the transparent film 3 is bonded to the back surface 9 of the substrate 2 by the adhesive. Therefore, when the stratum corneum observation tool 1 is viewed from the surface 4 side of the substrate 2,
The surface of the tongue 8 and the portion 10 of the transparent film 3 that closes the window 5 (hereinafter, this portion is referred to as a closed portion) are adhesive surfaces.

Next, a method of using the stratum corneum observation tool 1 will be described. First, the stratum corneum observation tool 1 is pressed against the skin, such as the face, so that the closed portion 10 of the transparent film 3 hits the site to be sampled. Transfer.

Next, an intermediate portion (indicated by a two-dot chain line in FIGS. 1 and 2) between the window hole 5 and the background portion 6 in the substrate 2 is set as a bending position 11 so that the surface 4 of the substrate 2 is located inside. The left portion (the side where the window hole 5 is present) 12 from the bending position 11 is changed to the right portion (the side where the background portion 6 is present) 13
Then, the adhesive surface of the tongue piece 8 is pressed against the surface 4 of the substrate 2 (see FIGS. 3 and 4).

In this case, since the tongue piece 8 is bonded to the surface 4 of the substrate 2 by the adhesive, the left portion 12 of the substrate 2 cannot return to the state before being folded. 2 is elastic, the left portion 12 of the substrate 2 tends to return to the state before bending. As a result, as shown in FIG.
From the left side 12 and the right side 1
A space 14 is formed between the first and third spaces. As a result, the closed portion 10 of the transparent film 3 is kept in a state where it is not pressed against the background portion 6.

In this state, looking at the transparent film 3 closing the window hole 5 in the left portion 12 of the substrate 2, the stratum corneum A adhered to the transparent film 3 against the black background portion 6.
Can be observed.

Since there is a space 14 between the closing portion 10 of the transparent film 3 and the background portion 6 of the substrate 2 and the closing portion 10 is kept in a state of not being pressed against the background portion 6, the space 14 The stratum corneum A adhering to the adhesive surface is not buried in the adhesive material of the closed portion 10 and taken in. Therefore,
The presence of the stratum corneum A attached to the closed portion 10 can be clearly recognized, and the stratum corneum A can be observed in detail.

In this embodiment, the transparent film 3
Although the adhesive applied to the bonding surface for bonding to the substrate 2 and the adhesive applied to the closing portion 10 for attaching the stratum corneum A are completely the same adhesive, for example, It is also possible to employ different types of adhesives depending on individual parts, such as making the former adhesive more adhesive than the latter adhesive.

[0019]

As described above, according to the stratum corneum observation tool according to the present invention, (a) a substrate having elasticity, (b) a window provided in the substrate, and (c) the substrate A dark background provided on the surface of the surface at a distance from the window hole,
(D) a transparent film that is bonded to the back surface of the substrate so as to close the window hole, and that is a portion corresponding to the window hole and has an adhesive adhered to the front surface side of the substrate. When the substrate is turned back after the horny layer is attached to the transparent film, a space is formed between the transparent film to which the horny layer is attached and the background portion of the substrate, and the two can be kept in a state where they are not pressed against each other. Therefore, an excellent effect is obtained in that the stratum corneum collected on the transparent film is very easily observed.

Further, when the transparent film has a tongue piece, the folded state having a space between the transparent film to which the stratum corneum is attached and the background of the substrate can be maintained.
