MULTI-CHAMBER FOG GENERATOR FOR GENERATING FOG CONTAINING A THERAPEUTIC AGENT

Abstract

A fog generator (500) intended to generate fog for inhalation by a user. The fog generator (500) comprises a first liquid chamber (546) containing a first liquid, a second liquid chamber (547) containing a second liquid, a first ultrasonic transducer (505) comprising a first flat atomization surface and a second ultrasonic transducer (506) comprising a second flat atomization surface.The first ultrasonic transducer (505) is configured to generate and transmit ultrasonic waves to generate a first part of the mist from the first liquid and the second ultrasonic transducer (506) is configured to generate and transmit ultrasonic waves to generate a second part of the mist from the second liquid, the first part of the mist and the second part of the mist combining to form the mist which flows out of a mist outlet orifice (208) for inhalation by the user.
