ABSTRACT:
An aerosol transfer device for medical aerosol generators comprises an elongate shaped hollow member, located in a vertical plane constituting an aerosol storage area. The member has a first opening allowing entry of outside air. The first opening is located on an upper or lower horizontal surface of the member to ensure vertical air entry. A second opening opposite said first opening allows escape of aerosol, and a third opening serves for spraying aerosol into the storage area in the vertical plane and in axial alignment with the air inlet opening. The member has a minimum height of 6 cm and allows dispersion of the sprayed aerosol without recycling aerosol deposited on the walls. The member is located between an aerosol generator source and a patient interface and does not include any valve on the aerosol path from the storage area to the patient.
