成果简介	NOVELTY - The device has a support sleeve (9), an acoustic speaker (8), a membrane (7), an internal fixed chassis (6), a cover (1), an external movable chassis (4), and an aerosol outlet fitting (3). The device is made with the possibility of obtaining a respirable aerosol fraction by changing the height of the outer movable chassis by varying the voltage and frequency of the supplied electric current to the sound generator. The device contains a fitting configured to supply a carrier gas, and is configured to fix the position of the outer movable housing relative to the fixed housing using a locking screw with a slot. The device is made with the possibility of formation and output through the aerosol outlet fitting of an aerosol torch, and is configured to mix with the carrier gas. USE - Dispersing device for dispersing powdered preparations for obtaining respirable fraction of aerosols to spray powdered drugs used in aerosol therapy and aerosol prevention of various diseases. ADVANTAGE - The device exerts a minimum mechanical load on the dispersible powder preparation, which allows the use of a wide range of substances, including those containing biologically active components. The device can obtain a respirable aerosol fraction of a powdered preparation with constant conditions of aerosol formation for a long period of time due to the formation of a fluidized bed, and control of the height of formation of the respirable aerosol fraction. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a dispersing device. 1Cover 3Aerosol outlet fitting 4External movable chassis 6Internal fixed chassis 7Membrane 8Acoustic speaker 9Support sleeve
