Abstract
An ultrasonic atomizer for respiration systems, which is integrated in the breathing gas line from and to the patient via two connections. The ultrasonic atomizer is in a gas flow connection with the atomizer chamber to which an aerosol is admitted by a piezo vibrating element for the inhalation via a nonreturn valve. The arrangement bridges over the atomizer chamber for the exhalation via a second nonreturn valve by means of a second, spatially separated gas flow path.
