Abstract

The claimed subject matter relates to a device for dosing and aerosolization of aerosolizable material. The device includes a body with an aerosolization channel with a distal attachment for connecting a source of carrier gas. The carrier gas provides pressure pulses to the aerosolization channel. A proximal attachment allows the aerosolized material to move to a reservoir for receiving the aerosolizable material. The reservoir is connected to the body via the 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.
