Abstract
L'invention concerne un nébulisateur ultrasonore Elle se rapporte à un nébulisateur ayant un circuit protecteur qui comprend un oscillateur relié à un transducteur par un composant inductif. Ce dernier est accordé afin qu'il fonctionne à la résonance avec la capacité apparente du transducteur. Une variation d'impédance de ce dernier, lorsque le liquide est supprimé ou consommé, réduit la puissance transmise au transducteur et empêche la détérioration de ce dernier. Application à l'administration des médicaments sous forme d'aérosols.
