Abstract

Det frembringes en iontoforetisk middelavgivelses-anordning (10) med donor- og motelektroder (11,12) av enten metall eller en hydrofob polymer hvori det er innblandet et ledende tilsatsmateriale. Middelreservoaret (15) i donorelek-trodekonstruksjonen (8) inneholder ca. 10-60 vekt% hydrofob polymer, ca. 10-60 vekt% hydrofil polymer, og opptil 50% av middelet. Tilsvarende omfatter elektrolyttreservoaret (16) ca. 10-60 vekt% hydrofob polymer, ca. 10-60 vekt% hydrofil polymer, og opptil 50% elektrolytt. Middelreservoaret (15), elektrolyttreservoaret (6) og elektrodene (11,12) dannes. ■fortrinnsvis i form av filmer som lamineres til hverandre. Den hydrofobe polymerkomponent i middel/elektrolyttreservoaret (15,16) forhindrer reservoaret i å delaminere fra den metall/ hydrofobe polymerbaserte elektrode (11,12) selv etter at reservoarene (5,16) er blitt hydratisert.
