Abstract
A turbine powered inhaler has a propeller mounted on a turbine shaft within an aerosolizing chamber. An air pathway extends from an inlet, through the turbine to the aerosolizing chamber, and out through a mouth piece. Upon inhalation by a patient, air flowing through the air path rapidly spins up the turbine which directly drives the propeller within the aerosolizing chamber. Air and drug particles are mixed and de-agglomerated in the aerosolizing chamber via the spinning propeller, without the need for a motor and batteries.
