ABSTRACT:
Inhalation therapy is not only used for the treatment of respiratory tract diseases, but also increasingly for administering other medicinal substances. In this kind of therapy, the substance is made available to the patient for inhalation in the form of a liquid vapor having very small droplet diameters (ca. 1 to 5 um) and is transported together with the inhaled air into the respiratory tracts. The inventive atomizer consists of a cylindrical atomizing space with two openings for respectively supplying and withdrawing the liquid vapor, the openings being arranged in such a manner that a spiral vortex is formed which extends about the longitidunal axis of the atomizing space.
