Abstract

The invention relates to a nebuliser comprising a nozzle 3 arranged in a nebulising space and an air inlet flue 5 projecting into the nebulising space. The nebulising space is subdivided by a nebulising space divider into two parts, so that proceeding from the nozzle an aerosol flow occurs from the one part into the other. According to the invention, additional impact faces 7 and 8 are provided in the direct vicinity of the nozzle, which have the effect that only the smallest liquid droplets reach into the upper region of the nebulising space and are available to the patient for therapy.
