Patent ID: 7980247

Claim:
Therapeutic aerosol device consisting of: a) a nebuliser device including aa) an aerosol generator to which a gaseous medium for the generation of a main aerosol flow may be supplied from a supply device, and bb) a pressure connection device to supply pressure fluctuations which are superimposed on the aerosol main flow, b) a nosepiece configured to supply the aerosol into one of the two alae of the nose of a user connected to the nebuliser device, and c) a flow resistance device configured to be placed at the other of the two alae of the user's nose, the flow resistance device causing aerosol from the main aerosol flow having pressure fluctuations superimposed thereon to reach the paranasal sinuses of the user and to be deposited therein, the flow resistance device being interchangeable with other flow resistance devices having different flow resistances.
