An aerosol transfer device for medical aerosol generators comprises an additional shaped element located in a vertical plane constituting an aerosol storage area. The additional element being designed with a first opening allowing movement of air from outside the storage area into the latter and being located on an upper or lower horizontal surface of the element in order to ensure vertical entry of air into the element, a second opening opposite said first opening allowing the escape of aerosol and a third opening for spraying aerosol into the storage area in the vertical plane of the storage area and in axial alignment with the first opening. The additional element has a minimum height of 6 cm and allows dispersion of the sprayed aerosol throughout the storage area without recycling the aerosol deposited on the walls of the storage area. The storage area is located between the aerosol generator source and the patient interface and allows, by means of a transport area, aerosol transport to the patient. The device does not include any valve on the path the aerosol takes from the storage area to the patient.
