A kind of device for reinforcing percutaneous absorbtion includes a carrier layer, a water conservation layer and a fixed cell. The carrier layer is suitble to adsorb a functional liquid, and the outer peripheral edge between the using face and the faying face is connected to including a using face, one and the reversed faying face of the using face and one. The water conservation layer is made of semipermeability material, is affixed the inner surface of touching with the faying face of the carrier layer including one. The first engaging portion between the faying face and the inner surface of the water conservation layer is arranged in along the outer peripheral edge of the carrier layer including one to prevent the water conservation layer mobile relative to the carrier layer for the fixed cell. The utility model is stably bound in the water conservation layer in the carrier layer, effectively prevent the water conservation layer with respect to the situation that the carrier layer is slided, thus can be easy to use and can ensure that more reliable Water-saving effect by the fixed cell is arranged.一種加強經皮吸收的裝置,包含一載體層、一保水層及一固定單元。該載體層適合吸附一功能液,包括一使用面、一與該使用面反向的結合面,及一連接在該使用面與該結合面間的外周緣。該保水層由半透過性材質製成,包括一與該載體層的結合面相貼觸的內表面。該固定單元用以防止該保水層相對該載體層移動,包括一沿該載體層的外周緣設置在該結合面與該保水層的內表面間的第一結合部。本新型藉由設置該固定單元,使該保水層穩定地結合在該載體層上,有效防止該保水層相對該載體層滑動的情形,因而能方便使用且可確保更可靠的保水效果。
