ABSTRACT:
A device for mouth-inhaling medicaments dispensed as aerosols by pressurized cans. The device is flat and compact in shape, and includes a seat for housing a can and defines an expansion chamber into which the aerosol dispensed by the can, when operated, penetrates and expands to circulate with a vortex flow which causes the solvent to evaporate and the flow movement to continue for a relatively long time, hence enabling only very small particles of the medicament to be drawn into the bronchial tubes and lungs. There is only minimum aerosol particle deposition on the walls of the oropharingeal cavity, and inhalation can continue after the entry of aerosol into the expansion chamber ceases.
