Summary:A system and method for use in iontophoretic anesthesia of a tympanic membrane are disclosed. The system generally includes an earplug and an electrode device. The earplug includes at least one sealing member for sealing the earplug in an ear canal. The sealing member includes microholes which vent fluid above a certain pressure threshold. A headset may connect the earplug to a second earplug. The method involves using the system on a human or animal subject. L'invention divulgue un système et un procédé à utiliser dans l'anesthésie iontophorétique d'une membrane tympanique. Le système comprend d'une manière générale un bouchon d'oreille et un dispositif d'électrode. Le bouchon d'oreille comprend au moins un élément d'étanchéité pour isoler le bouchon d'oreille dans le canal d'une oreille. L'élément d'étanchéité comporte des micro-trous qui évacuent le fluide au-dessus d'un certain seuil de pression. Un casque d'écoute peut raccorder le bouchon d'oreille à un deuxième bouchon d'oreille. Le procédé implique l'utilisation du système sur un sujet humain ou animal.
