Abstract
(EN)
An iontophoretic patch (5) for delivering a therapeutic agent into the skin of a user comprising a backing, having a lower surface (95) for housing a plurality of electrodes mutually spaced apart and a plurality of electrical conductors. Also included are reservoirs (50, 70) integral to the backing for containing a therapeutic agent and return solution. A barrier (100), integral to the backing, is substantially located between the reservoir and provides a point to break a conductive path of solution or perspiration between the reservoirs or components of the system.
(FR)
L'invention concerne un timbre (5) iontophorétique destiné à l'administration d'un agent thérapeutique dans la peau d'un patient. Le timbre iontophorétique comprend un support, présentant une surface inférieure (95) destinée à loger plusieurs électrodes espacées et plusieurs conducteurs électriques, ainsi que des réservoirs (50, 70) intégrés au support et destinés à contenir un agent thérapeutique et une solution récupérée. Une barrière (100) intégrée au support est située essentiellement entre les réservoirs et constitue un point de rupture d'un chemin de conduction de solution ou de transpiration entre les réservoirs ou des éléments du système.
