Patent number: 7858112Abstract: The present invention provides a percutaneous absorption system and a percutaneous absorption method, which have a simple constitution and can realize the easy and continuous percutaneous absorption of medicine even when the medicine is formed of a water-soluble oligomer solution or a high-molecular solution. In the percutaneous absorption system comprising a medicine reservoir portion having a medicine holding portion which holds medicine therein and a support portion for supporting the medicine reservoir portion, the support portion including an adhesive layer and a substrate having medicine non-permeating property, the system is provided with an elastic member for applying pressure to the medicine held in the inside of the medicine reservoir portion, and by breaking the substrate having medicine non-permeating property in the support portion using a mechanical stimulus such as an injection needle or the like, the medicine is released (delivered) at a fixed rate.Type: GrantFiled: February 26, 2003Date of Patent: December 28, 2010Assignees: Lintec CorporationInventors: Tomio Hatanaka, Rui Saito, Kenji Sugibayashi, Kiyose Nakagawa
