A device for administration of a medicated aerosol via the lungs consists of an inhalation mouthpiece , with an associated adjustable vaporizer , and of a compressed-air control valve through which a pre-settable ( ) volumetric flow of compressed air can be discharged to the vaporizer 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.

Precise administration of a medicated aerosol via the lungs

An ultramicroscopic spectrometer for examining properties of aerosol particles includes a receptacle having a wall defining a measuring chamber; an aerosol jet generating arrangement for forming an aerosol jet from the particles by aerodynamic focusing; a mount supporting the aerosol generating arrangement in the measuring chamber; a first passage in the receptacle wall for passing an incident illuminating beam through the receptacle wall into the measuring chamber; and a second passage in the receptacle wall for passing an information beam respectively an observation beam of the aerosol jet through the receptacle wall from the measuring chamber. The axes of the illuminating beam, the information beam and the aerosol jet intersect in a measuring field. The spectrometer further has a mount adjusting device arranged adjacent the receptacle base externally of the meauring chamber; a first coupling arrangement extending through an opening in the base and connecting the mount with the mount adjusting device and sealing the opening airtight; an astigmatic image forming system supported in the first passage for focusing the illuminating beam in a measuring field; and an adjusting-and-sealing assembly operatively connected to the second passage and displaceably coupled with the receptacle.
