[Experimental results and use of the manosonic aerosoliser (U.D.V.) for the treatment of middle-ear and affections (author's transl)]. / Experimentelle Grundlagen und Anwendung eines Ultraschallverneblers mit Druckstoss und Vibration (UDV) für die Aerosolbehandlung der Nebenhöhlen und des Mittelohrs.

The Manosonic Aerosoliser (UDV in German) is an Ultrasonic generator delivering a dense aerosol in a closed inhalating circuit in combination with temporary overpressures and sonic vibrations. In order to evaluate the efficiency of this new mode of areosoltherapy the Authors devised a glass model: a small vessel representing a sinus was connected to the aerosol stream by a little tube, a small ball being applicated by its own weight on the aperture to simulate the pathological obstructions (dyspermeabilities). The aerosol was made from a solution of Lithium Choloride and the amount introduced estimated by atomic absorbiton spectrometry. An increase of about 15 fold was found between ordinary and vibrated(sonic) aerosols and 35 fold more between vibrated and U.D.V. A short summary of clinical results is given as a confirmation of the expected efficacity of the U.D.V. treatment.
