Patent ID: 8006693

Claim:
An aerosol transfer device for a medical aerosol generator comprising an elongate shaped hollow member oriented in a vertical direction during use and constituting an aerosol storage area, said elongate shaped hollow member having a first air entry opening for introducing outside air from outside the storage area into the storage area during an inhalation phase of operation of the device, and said air entry opening being located on an upper or lower horizontal surface of said elongate shaped hollow member in order to ensure vertical entry of the outside air into said elongate shaped hollow member, a second opening and a third opening located near an opposite end of said elongate shaped hollow member from said first opening, said second opening serving to eject aerosol from said elongate shaped hollow member, said third opening serving for vertically spraying aerosol into the storage area, said elongate shaped hollow member having a minimum height of 6 cm and wherein an upper part of the elongate shaped hollow member has a cylindrical neck and a lower part has a bottomless tapered configuration in order to enhance the transport of aerosol within the elongate shaped follow member allowing dispersion without recycling aerosol deposited on walls of said elongate shaped hollow member, said storage area being located between an aerosol generator source and a patient interface and allowing, via a transport area, aerosol transport to a patient, and wherein the device does not include any valve in a path the aerosol takes from the elongate shaped hollow member that constitutes the storage area to the patient, and wherein, during inhalation, the outside air is vertically introduced into said storage area through said first opening and aerosol travels vertically in said storage area and is ejected through said second opening.
