Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a patch test tape to be applied to the skin to test the causative antigen of allergic contact dermatitis.

[0002]

[Prior Art]

 Conventionally, in order to search for the antigen causing allergic contact dermatitis, a patch test has been performed in which the antigen is applied to the skin for 24 to 48 hours and the antigen-antibody reaction that occurs on the skin is examined. The following patch test tapes are used for this purpose.

That is, as shown in FIGS. 7 to 9, the adhesive 2 is applied to the entire surface of the non-porous vinyl chloride sheet 1 to form a pressure-sensitive adhesive layer. A plurality of circular flannel pads 3 are provided at equal intervals in the center of the adhesive layer of the sheet 1 made of sheet, and an opening release paper 4 is provided at one end of the adhesive layer of the non-porous vinyl chloride sheet 1. At the same time, the covering release paper 5 covering the pad 3 overlaps with the opening release paper 4 and is attached over the entire area to the adhesive layer of the non-porous vinyl chloride sheet 1.

When using the above-mentioned patch test tape, first the peeling paper 5 for covering is peeled from the non-porous vinyl chloride sheet 1 to open the pad 3, and then the skin for inspecting the antigen / antibody reaction of the skin. A sticking test reagent (allergen) is applied to the surface of the pad 3, and then the reagent application part of the pad 3 and the adhesive layer of the non-porous vinyl chloride sheet 1 are pressed against the skin and a release paper for opening. 4 is peeled off, and the non-porous vinyl chloride sheet 1 is attached to the skin for a long time by the adhesive layer, and the antigen / antibody reaction of the skin is inspected.

[0005]

[Problems to be solved by the device]

 However, when the reagent is applied to the pad 3, since the adhesive layer of the non-porous vinyl chloride sheet 1 is pressed firmly with the finger, the non-porous vinyl chloride sheet 1 clings to the finger and adheres to the skin. In addition, there is a problem in that the adhesive force at the portion of the non-porous vinyl chloride sheet 1 pressed by the finger is reduced and the adhesive sheet may peel off from the skin during the antigen-antibody reaction test.

Further, the non-porous vinyl chloride sheet 1 is not breathable, and therefore, when the patch test tape is applied to the skin for a long time, the patch test tape application part of the skin is peeled off and the skin surface layer is inflamed. It often happened that the inflammation could not be distinguished from the skin antigen / antibody reaction.

In view of the above-mentioned circumstances, the present invention does not cause inflammation on the surface layer of the skin even when it is applied to the skin for a long time, and the handling such as application of the reagent to the pad or application to the skin is possible. It is an object of the present invention to provide a patch test tape which is easy and does not come off during the test of antigen-antibody reaction.

[0008]

[Means for Solving the Problems]

 In the present invention, an adhesive is applied to one surface of a breathable sheet to form an adhesive surface with an adhesive-free portion between the adhesive-applied parts, and a skin patch test reagent is applied or adsorbed. Affix the pad to the adhesive surface of the above-mentioned sheet through a film having chemical resistance and impermeability, and a release paper for holding along one side of the adhesive surface of the sheet so as not to cover the pad. A patch test tape, characterized in that the release sheet for covering is attached to the adhesive surface of the sheet so as to cover the pad and overlap with the release sheet for holding.

[0009]

[Action]

 After peeling off the covering release paper from the adhesive surface of the air-permeable sheet, press or hold the holding release paper with your finger to apply or adsorb the skin patch test reagent to the pad or to remove the adhesive surface of the sheet. Since it can be attached to the skin without directly contacting the adhesive surface, it is easy to handle and can be prevented from peeling off during the inspection, and the adhesive is applied so that there is a non-coated part. Since the adhesive surface of the sheet formed as described above is attached to the skin, the breathability is excellent, and the antigen / antibody reaction test can be reliably performed without causing inflammation on the skin surface layer.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a pressure-sensitive adhesive 12 is drawn on one surface of a rectangular non-woven fabric sheet 11 which is excellent in breathability and which does not hinder sweating so that a non-coated portion exists to form a pressure-sensitive adhesive surface.

Further, a film 14 made of vinyl chloride is attached to one surface of the pad 13 made of a circular flannel, and a plurality of pads 13 are arranged with the film 14 surface facing the adhesive surface of the nonwoven fabric sheet 11 (five in the figure). The non-woven fabric sheet 11 is attached to the adhesive surface of the non-woven fabric sheet 11 at equal intervals as shown in FIGS.

Further, a holding release paper 15 is attached to one end of the non-woven fabric sheet 11 on one long side of the adhesive surface as shown in FIG. 2 so as not to extend outside and cover the pad 13.

Furthermore, another length of the adhesive surface of the non-woven pressure-sensitive adhesive sheet 11 is such that the covering release paper 16 covers the pad 13 so that the end reaches the holding release paper 15 and overlaps with the holding release paper 15. It is attached as shown in FIGS.

Next, the use of the patch test tape having the above structure will be described.

First, the holding release paper 15 is pressed, and the end of the covering release paper 16 overlapping with the holding release paper 15 is lifted and peeled off from the nonwoven fabric sheet 11, and the state shown in FIGS. To the state of.

Next, the skin patch test reagent is applied (or adsorbed) to the pad 13, and the skin patch test reagent can be applied or adsorbed by fixing the holding release paper 15 with a finger. Therefore, the adhesive surface of the non-woven fabric sheet 11 does not cling to the fingers and is easy to handle, and since the vinyl chloride film 14 is interposed between the non-woven fabric sheet 11 and the pad 13, The skin patch inspection reagent does not leak outside from the non-woven sheet 11.

Thereafter, the holding release paper 15 is peeled off from the non-woven sheet 11 so that the surface of the pad 13 on which the reagent for inspecting skin sticking and the adhesive surface of the non-woven sheet 11 are brought into pressure contact with a desired portion of the skin, and the patch test tape is applied. Stick on the skin.

The application of the test agent for skin sticking to the pad 13 and the sticking of the patch test tape to the skin are performed by pressing the release paper 15 for holding without touching the adhesive surface of the non-woven sheet 11 directly. Since the adhesive strength of the adhesive surface of the non-woven fabric sheet 11 is not reduced, the patch test tape can be prevented from peeling off during the inspection.

The non-woven fabric sheet 11 uses a non-woven fabric with good breathability that does not prevent sweating, and forms an adhesive surface by drawing the adhesive 12 on one surface of the non-woven fabric sheet 11 so that there is a non-coated surface. Because of its excellent properties, even if the patch test tape is applied to the skin for a long time, it is possible to prevent inflammation on the surface layer of the skin, and to reliably test the antigen / antibody reaction of the skin.

5 and 6 show another embodiment of the present invention.

That is, a length of the adhesive surface of the non-woven fabric sheet 11 is set so that the holding release paper 17 whose long side ends are bent has its bent portion 17 a on the pad 13 side and does not cover the pad 13. The peeling paper for covering is attached to the side edge portion while sticking out to the outside, and covers the pad 13 so that the edge reaches the bent portion 17a of the holding peeling paper 17 and overlaps with the bent portion 17a. 16 is affixed to the other end of the non-woven fabric sheet 11 on the longer side of the adhesive surface so that the holding release paper 17 can be easily removed from the non-woven fabric sheet 11 by utilizing the bent portion 17a. It can be peeled off for convenience during use.

The present invention is not limited to the illustrated and described embodiments, but can be used, for example, by cutting it from a required place (a place A or B in FIG. 3) and using a pressure-sensitive adhesive in a grid-like non-woven fabric. It is formed by applying it to a sheet, making it a shape other than a rectangle, or by using a material with air permeability such as cloth, paper, or synthetic resin tape with holes punched to maintain air permeability. It is optional to use a sheet instead of a non-woven sheet, and it need not be a vinyl chloride film as long as it has chemical resistance and impermeability. It goes without saying that various changes can be made without departing.

[0024]

[Effect of the device]

 As described above, according to the patch test tape of the present invention, since it has good air permeability, it is possible to prevent inflammation on the surface layer of the skin even when it is applied to the skin for a long time, and it It is possible to eliminate clinging because the holding release paper is pressed with your finger when applying, fixing and pressing the skin application test reagent of the pad and the adhesive surface of the breathable sheet to the skin. Since it does not come into direct contact with the adhesive surface of the breathable sheet and there is no decrease in adhesive strength, it does not peel off from the skin during a long-term inspection, With the combination of sticking without peeling off time and prevention of inflammation on the skin surface, it is possible to reliably perform antigen / antibody reaction test on the skin, and moreover, the structure is simple and easy and inexpensive to manufacture. It can have excellent effects.
