The invention relates to an inhaler for atomization, dispersing and mixing of fluid or powdery substances by means of a pressurized gas flow (30) for production of an aerosol. The inhaler consists of an atomization head (1) arranged in the upper end of a two part hand grip (2). The atomization head (1) has a central atomization nozzle comprised of a nozzle head (23) and a gas flow controller (27), a connection passage (21) for pressurized gas supply, an air supply chimney (28) and an aerosol outlet passage (28) for connection to a mouthpiece. The nozzle head (23) contains a central pressurized gas passage (22) and lateral suction channels (24,25) for the atomization material (26). According to the invention the atomization head (1) has a spherical shape and is surrounded by correspondingly shaped hollow spherical parts (5,6) of the hand grip. The low height is achieved in that between the container (18) receiving the atomization material (26) and the cap (19), an insert (20) and a deflector (31) on the lower edge of the air supply chimney (28) are provided, by which the aerosol flow produced is guided in a labyrinthine manner via an edge (32) on the deflector (31) and an edge (33) on an insert (20) to the outlet passage (29). In this way, larger particles unsuitable for lung ingestion (extra thoracic) are excluded.

Inhaler

The invention relates to a spray-diffuser for the atomization of liquids or solid substances, such as medicaments, with the help for the flow of compressed air, particularly for inhalation purposes. The spray-diffuser comprises a spray-diffuser nozzle (3) located in an atomizing chamber (10), which nozzle is connected to a compressed air channel (2) and comprises a suction device for sucking up the medicament, wherein the compressed air channel adjacent the nozzle has a release opening (15) for escape of the compressed air, which opening is settable to a non-operation position, and which can for example be closed during inhalation of the patient and opened during exhalation of the patient. In known spray-diffusers, diverted air is guided through the release opening with a development of a hissing noise and a danger of harm to the staff. In order to avoid this disadvantage, in the spray-diffuser according to the invention the release opening leads into the atomizing chamber. Expediently, the release opening is positioned on that side of the compressed air channel which is averted from the supply chambers 7 for the substance to be atomized.
