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.

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.

の考案者の知見に基づいて完成された。(Means for Solving the Problems) The present invention prevents the adhesive in the patch from oozing out by covering the edges of the patch with an adhesive sheet, or prevents the adhesive from leaching 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 surrounding area; in addition, by providing a notch on the inner peripheral 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

とにより上記目的が達成される。 The adhesive sheet for fixing a patch of the present invention is an adhesive sheet having an annular or frame-like planar shape that can cover the end of a patch of any shape, and
It has a base material and an adhesive layer, and has cutouts in at least two places on the inner circumferential surface of the adhesive sheet that allow the positional relationship between the adhesive sheet and the patch to be visually observed, thereby achieving the above-mentioned purpose. is achieved.

粘着剤には、例えば、アクリル重合体系の粘着剤

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.

ないでそのまま使用される。 The reinforcing sheet is used to cover the surface of the base material opposite to the surface in contact with the adhesive layer to compensate for the lack of strength of the base material or to improve workability during use. For example, when the base material is a polyurethane film, the reinforcing sheet is used as it is without peeling off the process paper used for casting upon which the polyurethane film is formed.
本考案の粘着シートの形状は、特に限定されな

At this time, the adhesive patch S is formed in a shape that can completely cover the end portion of the adhesive patch S. This adhesive sheet includes a frame-shaped base material 1 and a frame-shaped adhesive layer 2.

しない。 This adhesive sheet is adhered to the end of 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.

Thereby, the bias of the pressure-sensitive adhesive sheet relative to the adhesive patch S can be confirmed. When a deviation is confirmed, the adhesive sheet is corrected to the correct position relative to the patch and applied to a predetermined position on the skin.

トは、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. This device prevents the adhesive from seeping outside or from peeling off when the adhesive strength is insufficient, so you can use the adhesive that best suits the drug without worrying about this. It can be adopted for use.
Moreover, this pressure-sensitive adhesive sheet is provided with a notch on its inner circumferential surface, so that 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 adhesive sheet can be accurately fixed to the patch while correcting the bias of the patch. As a result, the adhesive sheet of the present invention is useful for fixing adhesive patches.
