Abstract

L'invention concerne un système transdermique (1) d'administration passive d'une substance à travers la peau, qui comprend un réservoir comportant une couche de stockage (2) pour les substances à administrer, ainsi qu'un dispositif de transfert. Pendant le processus d'administration, ce dispositif de transfert est aussi bien en contact avec le réservoir qu'avec la peau. Il est également prévu dans ce système transdermique (1) des électrodes (4, 5) qui produisent un courant qui initialise le système et sert à transporter la substance de la couche de stockage dans une couche de modification (3) contenue dans le dispositif de transfert. Ce système transdermique (1) permet également d'administrer plusieurs substances à travers la peau d'un patient.
