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.

1. Nebuliser device for inhalation therapy apparatus, comprising: an element for supplying a compressed gas, in particular compressed air;an element for supplying a fluid to be nebulised, in particular a therapeutically effective liquid;a plurality of compressed gas outlet openings, out of which the supplied compressed gas emerges; anda plurality of fluid outlet openings, out of which the fluid to be nebulised emerges owing to the emerging compressed gas:whereinat least three compressed gas outlet openings are arranged in a row; andat least two fluid outlet openings are allocated to each of the compressed gas outlet openings, which, together with the associated compressed gas outlet opening, form a nebuliser nozzle, andwhereinthe compressed gas outlet openings have diameters of less than 0.4 mm and at least two of the compressed gas outlet openings have diameters that are different from each other. 2. The nebuliser device according to claim 1, wherein the compressed gas outlet openings having larger diameters are arranged towards a centre of the row of compressed gas outlet openings. 3. The nebuliser device according to claim 1, wherein the compressed gas outlet openings having larger diameters are arranged at an edge of the row of compressed gas outlet openings. 4. The nebuliser device according to claim 1, wherein the diameters of the compressed gas outlet openings of the row of compressed gas outlet openings are symmetrically arranged to a centre of the row. 5. The nebuliser device according to claim 1, wherein a gas flow control is provided opposite the compressed gas outlet openings, said gas flow control being configured in an elongated manner to face the nebulizer nozzle openings being arranged in said row. 6. The nebuliser device according to claim 5, wherein the gas flow control has a surface facing the compressed gas outlet openings that is cuneiform or rounded. 7. The nebuliser device according to claim 1, wherein a baffle rod is provided for each compressed gas outlet opening, which is arranged opposite the compressed gas outlet opening. 8. The nebuliser device according to claim 7, wherein the baffle rod has a surface facing the compressed gas outlet openings that is pointed or rounded. 9. The nebuliser device according to claim 1, wherein the fluid outlet openings are circular. 10. The nebuliser device according to claim 1, wherein the fluid outlet openings are slots. 11. The nebuliser device according to claim 10, wherein the slots extend parallel to the row of compressed gas outlet openings. 12. The nebuliser device according to claim 1, wherein fluid channels extending to the fluid outlet openings are provided. 13. The nebuliser device according to claim 1, wherein the compressed gas outlet openings have a diameter of between 0.1 and 0.4 mm. 14. The nebuliser device according to claim 1, wherein the compressed gas outlet openings have a diameter of between 0.1 and 0.3 mm.
