Abstract

The invention relates to a device 1 for dosing and dry nebulization of nebulizable material 12 chosen from the group comprising anti-infective agents and immunomodulators, comprising a nebulization channel 3, which has a first attachment piece and a second attachment piece, and a source of compressed carrier gas connected to the first attachment piece via a valve 16 for the purpose of sending a carrier gas pressure pulse into the nebulization channel. The device is characterized in that between the first attachment piece and second attachment piece, and above the nebulization channel, a reservoir 10 open only towards the nebulization channel, which contains the nebulizable material 12, is connected to the nebulization channel such that it is gas-tight with respect to the environment, and that, when the valve is closed, a pressure compensation takes place in the nebulization channel and in the reservoir. The invention also relates to a method for dosing and dry nebulization of such a nebulizable material by means of such a device.
