摘要： An aerosol delivery device is provided that includes at least one housing, a nozzle, a piezoelectric or piezomagnetic material, a control component, and a transport element. The at least one housing may enclose a reservoir configured to retain an aerosol precursor composition. The nozzle may be coupled to the housing to discharge aerosol precursor composition from the reservoir. The control component may include a microprocessor coupled to and configured to drive the piezoelectric or piezomagnetic material to vibrate and cause a discharge of components of the aerosol precursor composition and thereby produce an aerosol for inhalation by a user. And the transport element may be configured to control an amount of aerosol precursor composition delivered from the reservoir.

摘要： The present invention provides a breath-actuated inhalation device comprising: an aerosol generator comprising a vibrator and a membrane; and a reservoir for liquid to be aerosolized which is in fluid communication with the membrane. A method for operating the device is also provided. The vibrator is driven intermittently so that the aerosol generator has periods of aerosol generation during a patients inhalations and periods of little or no aerosol generation preceding and/or succeeding the inhalations Scans are performed in which an electrical parameter of the vibrator is measured as the membrane is vibrated at a plurality of frequencies. The spectrum obtained from a scan during an inhalation is compared with a spectrum obtained from a scan during the period preceding or succeeding that inhalation in order to determine whether liquid is present in the reservoir.

摘要： Provided herein are devices, systems, and methods for providing respiratory therapy to a patient using a nasal cannula comprising a cannula body, first and second inlet tubes, and a nasal prong for the delivery of a flow of breathing gas to the patient. Configured with the cannula is a nebulizer having an aerosol generator positioned to emit aerosolized medicament along a longitudinal axis of the nasal prong. A flow director is configured to direct the flow of breathing gas into the nasal prong such that the breathing gas flows along the longitudinal axis, such that the flow of aerosolized medicament is contained within the flow of breathing gas as it moves along the longitudinal axis of the nasal prong for delivery to the patient.

摘要： An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

摘要： An aerosol delivery system has an aerosol generator with a vibrating aperture plate (10) and an actuator (11, 16, 17, 19), a controller (18, 19). The controller in real time monitors (201) the aerosol generator as it is driven for vibration of the aperture plate, and detects (202) a change in an electrical characteristic in response to a transition from a wet state to a dry state of the aperture plate. It automatically modifies (203, 205, 206), during the transition, operation of the aerosol generator in response to the detected change. The modification includes reducing applied power (203). The controller continues (204) to monitor during the transition, including monitoring the aperture plate for presence of residual liquid on the aperture plate first surface. The controller monitors at a number of drive frequencies and maintains data representing trends in a combination of the electrical characteristic signals at the different frequencies, and identifies a start of a transition if a calculated value rises above a threshold. There is one threshold for triggering a check scan for residual volume and a higher threshold to trigger an immediate shut down.
