The device has a compressor (1) for providing an air flow, and a nebulization device (2) for generating an aerosol flow. A mixing device (3) is used for optionally mixing the aerosol flow with the air flow to provide a total flow, where the total flow includes the aerosol flow and/or the air flow. An air channel (4) is arranged between the compressor and the nebulization device. Another air channel (5) is arranged between the compressor and the mixing device. A venturi nozzle (6) is provided as an amplification device (6) for increasing the air flow provided by the compressor.
