Dropsonic™PLUS produces high frequency electrical signals and turns these signals into mechanical ultrasonic vibrations using a piezzo ceramic crystal. These vibrations pass through the liquid inside the ultrasonic chamber and focus on the surface of the liquid that will make the liquid aerosolized from the surface and maintain the aerosol mist. Due to continuous ultrasonic crystal activity, a fine and dense mist is formed at the chamber and this mist is given to the patient by the airflow which is generated by the device itself.
