  • METHOD FOR DETECTING THE PRESENCE OF LIQUID IN A VIBRATING MEMBRANE NEBULIZER
    Publication number: 20230390507
    Abstract: The present invention provides a vibrating membrane nebulizer with an aerosol generator comprising a vibrator and a membrane, a reservoir for liquid to be aerosolized, a channel and an optical sensor for detecting the presence of aerosol in the channel. The device determines whether aerosol is present in the channel on the basis of the output signal from the optical sensor, in order to detect when the reservoir becomes empty, and stops vibration of the membrane if it determines that no aerosol is present. A method for operating the device is also provided.
