Abstract

Un système d'électrotransport (50) comprend un dispositif de commande réutilisable (52) doté d'une source d'énergie (60) et un module jetable séparé (70) contenant un médicament. Le dispositif de commande (50) comporte un commutateur (62) qui débranche la source d'énergie (60) du consommateur de courant quand le dispositif de commande (52) est découplé du module à médicament (70). Un dispositif de couplage (74, 66, 105, 72, 64, 104) couple matériellement et électriquement ce dispositif de commande (52) et ce module à médicament (70) de façon que le dispositif (52) fournisse un courant électrique au module (70) et que le médicament soit libéré par électrotransport sur une surface d'un corps (par exemple sur la peau) d'un patient.
