Patent ID: 8387895

Claim:
An inhalation therapy device comprising: a liquid storage container into which a liquid can be filled; an aerosol generator comprising: a membrane which is arranged with respect to the liquid storage container such that a liquid filled into the liquid storage container comes into contact with one side of the membrane; and a vibration generator capable of causing the membrane to vibrate such that a liquid filled into the liquid storage container is nebulized and expelled as an aerosol on the other side of the membrane through openings of the membrane at an aerosol generation rate in the range of about 0.2 ml/min to about 1.5 ml/min; a mixing chamber into which the aerosol generator delivers the aerosol and which has a volume in the range of about 60 ml to about 150 ml; an inhalation valve that is open to allow an inflow of ambient air into the mixing chamber during an inhalation phase and is closed to prevent escape of the aerosol from the mixing chamber during an exhalation phase; and an exhalation valve that is open to allow the discharge of the respiratory air of a patient into the surroundings during the exhalation phase and is closed to prevent the inflow of ambient air during the inhalation phase.
