Abstract

The claimed subject matter relates to a device for dosing and aerosolization of aerosolizable material. The device comprises: a body with an aerosolization channel with a distal attachment portion connectable to a source of carrier gas which provides pressure pulses to the aerosolization channel; a proximal attachment portion for outputting aerosolized material and a reservoir for receiving aerosolizable material. The reservoir comprises walls and is connected in a gas-tight manner to the body and in fluid connection with the aerosolization channel. At least part of the walls of the device are self-exciting membranes that can be put into oscillation by the pressure pulses.
