Zusammenfassung:PROBLEM TO BE SOLVED: To provide a device for causing the transdermal flux of a permeant into a patient via at least one pathway formed through a skin layer of the patient.SOLUTION: The device comprises a delivery reservoir 20 comprising: i) a non-biodegradable matrix having a bottom surface 24 and defining a plurality of conduits therein (at least a portion of the plurality of conduits being in communication with the bottom surface); and ii) an undissolved hydrophilic permeant disposed in at least a portion of the plurality of conduits of the matrix (where, the hydrophilic permeant can come in contact with subcutaneous fluid from the patient when the bottom surface of the matrix is positioned in fluid communication with the at least one formed pathway).SELECTED DRAWING: Figure 1 【課題】患者の皮膚層を通る少なくとも1つの形成された経路を介する患者への浸透物の経皮流動を引き起こすためのデバイスの提供【解決手段】i)底表面24を有し、マトリックスの中の複数の導管を規定する非生分解性マトリックス(複数の導管の少なくとも一部が底表面と連絡している);およびii)マトリックスの複数の導管の少なくとも一部に配置された非溶解親水性浸透物(ここで、マトリックスの底表面が、少なくとも1つの形成された経路との流体通路に位置する場合に、親水性浸透物は患者からの皮下液と接触することができる);を含むデリバリーリザーバー20を含む構成とする。【選択図】図1
