Abstract

A device for administration of a medicated aerosol via the lungs consists of an inhalation mouthpiece 11, with an associated adjustable vaporizer 12, and of a compressed-air control valve 14 through which a pre-settable (13) volumetric flow of compressed air can be discharged to the vaporizer 12 containing the liquid medicament throughout a settable period of time. For operation of the device an electronic controller is provided on which the vaporizing period of the vaporizer and a pause interval can be set, with provisions being made for triggering the beginning of the vaporizing operation by means of a pressure sensor responsive to a suction pressure in the mouthpiece.
