る。[Detailed description of the invention] (Field of industrial application) The present invention is an adhesive sheet for fixing a patch, in particular, effectively prevents the adhesive in the patch from leaching and being exposed to the skin surface, thereby making the adhesive more sticky. The present invention relates to an adhesive sheet for fixing a patch that can prevent the adhesive from adhering to the peripheral area.

が容易に剥離する。 In order to efficiently transfer the drug in the adhesive layer to the skin, the adhesive layer needs to have adhesion to the skin. For this purpose, a flexible adhesive with low cohesive force is used in the adhesive layer. Moreover, the thickness of the adhesive layer is increased. When a patch having such an adhesive layer is applied to the skin, the adhesive containing the drug is likely to leak into the periphery of the application site. Since the leached adhesive is exposed on the skin surface, it stains the surrounding area by adhering to clothing and causing discomfort to the user. The drug adheres to the surrounding area along with the adhesive, reducing its efficacy by that much. If the adhesive oozes out and adheres to the surrounding area, the adhesive force of the patch will decrease and may cause the patch to peel off. In order to prevent the adhesive from adhering to the periphery, attempts have been made to reduce the leaching of the adhesive by using an adhesive that lacks flexibility and has high cohesive strength in the adhesive layer of the patch. . However, in a patch having such an adhesive layer, the drug in the adhesive layer does not sufficiently transfer to the skin due to the cohesive force of the adhesive, and the desired medicinal effect cannot be obtained. Since adhesives with high cohesive strength have low adhesive strength, the adhesive layer lacks adhesion to the skin, and the patch easily peels off.

シートを提供することにある。(Problems to be solved by the invention) The present invention solves the above conventional problems, and its purpose is to effectively prevent the adhesive in the patch from being exposed to the skin surface. An object of the present invention is to provide a pressure-sensitive adhesive sheet for fixing a patch, which can thereby prevent the pressure-sensitive adhesive from adhering to the peripheral area. Another object of the present invention is to provide a pressure-sensitive adhesive sheet for fixing a patch that can evenly fix the patch. Still another object of the present invention is to provide a pressure-sensitive adhesive sheet for fixing a patch, in which the deviation of the pressure-sensitive adhesive sheet relative to the patch can be easily determined.

た。(Means for Solving the Problems) The present invention provides that by covering at least the edges of the patch with an adhesive sheet, leaching of the adhesive in the patch is prevented or the adhesive is leached out. Since the adhesive is not exposed to the skin surface even when the adhesive is applied, it can effectively prevent the adhesive from adhering to the peripheral area; in addition, by providing a notch on the outer circumferential surface of the adhesive sheet, it is easy to bias the adhesive sheet against the patch. It was completed based on the inventor's knowledge that it is possible to distinguish between

る。 The adhesive sheet for fixing a patch of the present invention is an adhesive sheet that can cover at least the end of a patch of any shape, and has a base material and an adhesive layer, and has a base material and an adhesive layer, The adhesive sheet has at least two notches that allow the positional relationship between the adhesive sheet and the adhesive patch to be visually observed, thereby achieving the above object.
基材には、例えば、軟質プラスチツク発泡シー

ートの発泡倍率は10％以上が好ましい。 For example, a soft plastic foam sheet or a polyurethane film is used as the base material. The foaming ratio of the foam sheet is preferably 10% or more.

粘着剤には、例えば、アクリル重合体系の粘着剤
がある。特に、ガラス転移点（Tg点）が−50℃
以上の粘着剤や微架橋された粘着剤が好ましい。 The adhesive used in the adhesive layer is a substance that has higher cohesive force and less fluidity than the adhesive contained in the adhesive patch. If the cohesive force of the adhesive is low or the fluidity is high, the adhesive of the adhesive sheet will ooze out to the periphery and be exposed on the skin surface, making it impossible to achieve the purpose of the present invention. The thickness of the adhesive layer also
It is thinner than the adhesive layer of the patch. If the layer thickness is too thick, there is a risk that the adhesive of the adhesive sheet will seep into the periphery, as described above. The adhesive used in this adhesive layer includes, for example, an acrylic polymer adhesive. In particular, the glass transition point (Tg point) is -50℃
The above adhesives and slightly crosslinked adhesives are preferred.

The film is used with the casting mount used during film formation still attached.

で貼着されるのが好ましい。 The shape of the pressure-sensitive adhesive sheet of the present invention is not particularly limited, but it needs to be able to completely cover at least the edges of the patch to be used. The pressure-sensitive adhesive sheet is preferably attached approximately 10 to 20 mm outward from the outer periphery of the patch.
本考案の粘着シートは、例えば、第１図に示す

面の４隅のそれぞれには、切欠部Ｐが設けられて
いる。 For example, as shown in FIG. 1, the adhesive sheet of the present invention is a flat plate with a two-layer structure, and when placed along the periphery of the patch S to be applied to the skin,
It is made in a shape that can completely cover the adhesive patch S. This adhesive sheet is formed by laminating a flat base 1 and a flat adhesive layer 2. Notches P are provided at each of the four corners of the outer peripheral surface of the flat plate.

るいは粘着剤が浸出しても皮膚表面に露呈しな
い。 This adhesive sheet is adhered to the patch S and the skin surface by the adhesive force of the adhesive layer 2. Thereby, the patch S is fixed to the skin surface. Therefore, since the end surface of the patch is covered with the adhesive sheet, the adhesive in the patch is prevented from leaching, or even if the adhesive leaches out, it is not exposed to the skin surface.
この粘着シートを貼付剤および皮膚表面に貼着
するに際し、貼付剤Ｓに対し粘着シートが偏つて

偏りを確認することができる。偏りが確認された
ときには、粘着シートを貼付位置を修正しながら
粘着シートを貼付剤に対し正しい位置に配置し皮
膚の所定位置へ貼着する。 When applying this adhesive sheet to the patch and the skin surface, if the adhesive sheet is biased with respect to the patch S, the area of the end of the patch S that is visually observed from the notch P will be smaller than the four notches. The size of the part P is different. Thereby, the bias of the pressure-sensitive adhesive sheet relative to the adhesive patch S can be confirmed. When the deviation is confirmed, the adhesive sheet is placed in the correct position with respect to the patch while correcting the application position and is applied to the skin at a predetermined position.

着され得るため好ましい。 Another example of the adhesive sheet of the present invention has a frame shape with a hollowed out central portion. This adhesive sheet is
Compared to the above-mentioned flat plate structure, since it is attached only to the edges of the adhesive patch, it is possible to prevent the central part from becoming bulky or stiff, and it can be applied more reliably, which is preferable.

は、貼付剤の固定に有用である。(Effects of the invention) Since the adhesive sheet for fixing a patch of the present invention can cover the edges of the patch in this way, the leaching of the adhesive in the patch is prevented or the adhesive is Even if leached, it will not be exposed on the skin surface. therefore,
The leached adhesive will not adhere to the surrounding area, staining the surrounding area, or reducing the medicinal efficacy of the patch. As a result of using an adhesive with high cohesive force to prevent leaching of the adhesive, there is no fear that the medicinal efficacy will decrease.
Furthermore, this pressure-sensitive adhesive sheet is provided with a notch on its outer peripheral surface, and therefore, the bias of the pressure-sensitive adhesive sheet relative to the patch can be easily determined based on the area of the patch that can be visually observed from the cut-out. Thereby, the bias of the patch can be corrected and the adhesive sheet can be accurately fixed to the patch. As a result, the adhesive sheet of the present invention is useful for fixing adhesive patches.
