Abstract

UN DISPOSITIVO IONTOFORETICO PARA LA DISTRIBUCION DE UN MEDICAMENTO COMPRENDE UN SOPORTE FLEXIBLE NO CONDUCTOR (12); PRIMERO (16) Y SEGUNDO (18) ELECTRODO FORMADOS SUBSTANCIALMENTE POR MATERIAL NO IONIZANTE EN UN PLANO, UNA CARA DEL PLANO QUE SE UNE OPCIONALMENTE AL SOPORTE FLEXIBLE OPCIONALMENTE (12), Y LA OTRA CARA DEL PLANO QUE SE ADAPTA PARA FIJARSE A UNA CARA DE UNA CAPA ELECTRICAMENTE CONDUCTORA Y FLEXIBLE QUE CONTIENE EL MEDICAMENTO A DISTRIBUIR; UNA FUENTE (34) DE CORRIENTE ELECTRICA Y UN CIRCUITO INTEGRADO (30) QUE CONTIENE UN MEDIO PARA INVERTIR LA POLARIDAD DE LOS DOS ELECTRODOS. EL DISPOSITIVO PUEDE INCLUIR ADICIONALMENTE LA CAPA CONDUCTORA QUE CONTIENE EL MEDICAMENTO A ADMINISTRAR, UNIDO AL PLANO DE LOS DOS ELECTRODOS. SE PUEDE DISPONER OPCIONALMENTE UNA MEMBRANA DE INTERCAMBIO DE IONES ENTRE LOS DOS ELECTRODOS Y LA CAPA QUE CONTIENE EL MEDICAMENTO. EL CIRCUITO INTEGRADO (30) PUEDE CONTENER OPCIONALMENTE MEDIOS DE IMPULSOS O MEDIOS DE VARIACION DE CORRIENTE O AMBOS PARA VARIARLA CANTIDAD DE CORRIENTE SUMINISTRADA PARA UN PERIODO DE TIEMPO DETERMINADO O EN LA CANTIDAD ABSOLUTA.
