Abstract: front page image
(EN)A transdermal drug administration device which comprises a patch (12) that is provided with: a donor gel (30) in which a medical agent is sealed; a reference gel (34); a first electrode (38) that is connected to the donor gel (30); and a second electrode (40) that is connected to the reference gel (34). When the patch (12) is applied to the skin, a direct current is applied between the first electrode (38) and the second electrode (40) at a predetermined cycle and an alternating current is applied between the first electrode (38) and the second electrode (40) during the periods when a direct current is not applied, thereby obtaining the capacitance. The application state of the patch (12) is determined based on the thus-obtained capacitance.
(FR)L'invention porte sur un dispositif transdermique d'administration de médicament qui comprend un timbre transdermique (12) qui comporte : un gel donneur (30) dans lequel un agent médical est scellé de manière étanche; un gel de référence (34); une première électrode (38) qui est connectée au gel donneur (30); et une seconde électrode (40) qui est connectée au gel de référence (34). Lorsque le timbre transdermique (12) est appliqué sur la peau, un courant continu est appliqué entre la première électrode (38) et la seconde électrode (40) à un cycle prédéterminé et un courant alternatif est appliqué entre la première électrode (38) et la seconde électrode (40) durant les périodes durant lesquelles un courant continu n'est pas appliqué, permettant ainsi d'obtenir la capacité. L'état d'application du timbre transdermique (12) est déterminé sur la base de la capacité ainsi obtenue.
