To increase the efficacy of atomizer nozzles operating with compressed gas, an atomizer device for inhalation therapy appliances includes means for delivering a compressed gas, in particular compressed air; means for supplying a fluid that is to be atomized, in particular a therapeutic liquid; several compressed gas outlet openings from which a delivered compressed gas emerges; and several fluid outlet openings from which the fluid to be atomized emerges on account of the emerging compressed gas. The atomizer device includes at least three compressed gas outlet openings arranged in a row, and one of the compressed gas outlet openings is in each case assigned at least two fluid outlet openings which, together with the associated compressed gas outlet opening, form an atomizer nozzle.
