Abstract

The invention relates to a device for atomising, distributing and mixing liquid or pulverulent substances by means of a stream of compressed gas, and it is particularly intended for the production of aerosols for inhalation purposes. A nozzle head (5) working on the Venturi principle is used to produce an aerosol from material to be atomised and stored in a container (1). An extended deflector shield (4) is provided at the level of the opening of the nozzle head and at the lower end of a chimney (3) for the supply of air. In order to form a labyrinth guide there is a cylindrical insert (7) which establishes an annular gap around the chimney (3). The proportion of aerosol particles (diameter about 0.5 to 5 mu m) that can reach the lungs is considerably increased by the extension of the deflector shield. <IMAGE>
