  • Device and method for determining an aerosol delivery
    Patent number: 11992606
    Abstract: A device for determining delivery of an aerosol stream has a collector having a filter for collecting aerosol particles in the aerosol stream, a first fluid connection point connectable to an aerosol generator, and a second fluid connection point connectable to a breathing simulator for simulating tidal breathing, at least one measurement volume for an interaction of at least one light beam with the aerosol particles passing through the measurement volume, at least one optical measurement unit for generating at least one optical measurement signal depending on the interaction of the at least one light beam with the aerosol particles passing the measurement volume, and at least one evaluation unit for determining the aerosol delivery of the aerosol stream from the at least one optical measurement signal. A method determines an absorption and/or adsorption of a liquid on aerosol particles.
