Device for dosing and dry nebulization

摘要

A device 1 for dosing and dry nebulization of nebulizable material 12, comprising a nebulization channel 3 which has a first attachment piece 18 and a second attachment piece 6/7, and a source of compressed carrier gas connected to the first attachment piece 18 via a valve 16 for the purpose of sending a carrier gas pressure pulse into the nebulization channel 3. Between the first attachment piece 18 and second attachment piece 6/7 and above the nebulization channel 3 is a reservoir 10 open only towards the nebulization channel 3 which contains the nebulizable material 12. The reservoir 10 is connected to the nebulizaton channel 3 such that it is gas-tight with respect to the environment. When the valve 16 is closed a pressure compensation takes place in the nebulization channel 3 and in the reservoir 10.
