ABSTRACT:
A device for generating an aerosol in the course of a respiration gas line, which leads from a respirator to a patient for the patient's artificial respiration. The dead space volume existing during the artificial respiration is minimized, and it is possible to arrange the generating device as close to the patient as possible in the course of the respiration gas line. In the interior space of the respiration gas line, an ultrasound generator unit (11, 12), which has a vibrating surface (14), above which a metering line (16) opens, and predeterminable amounts of the liquid to be atomized are delivered from a metering unit (16) outside the respiration gas line (6).
