ABSTRACT:
A device for use with a medicinal inhalation device comprises a rotationally symmetrical chamber having an opening to be connected to a spray nozzle and a mouthpiece. The chamber diverges conically from the opening and converges towards the mouthpiece. During passage through the chamber, an aerosol mist will lose propellant by evaporation, and smaller particles will be generated which can more readily follow the path of inhalation.
