  • Patent number: 8875697
    Abstract: A drug delivery apparatus includes a mouthpiece portion having an internal conduit for delivering an aerosol including the drug to the patient. The internal conduit has an inlet end and a mouthpiece end that is structured to be received in the patient's mouth. The mouthpiece portion is structured to operate at a substantially fixed inhalation flow rate when the patient inhales through the mouthpiece end. The apparatus further includes an aerosol generator for generating the aerosol from a drug supply and injecting the aerosol into a first region within the mouthpiece portion located between an outlet of the aerosol generator and the inlet end of the conduit. The mouthpiece portion also includes a flow accelerating mechanism that causes a localized flow rate at the first region to be greater than the inhalation flow rate. A method is also provided that increases the local flow rate within the mouthpiece portion.

  • Patent number: 8607786
    Abstract: A drug delivery apparatus of the type which releases a drug in aerosolized form into the inhaled airstream of a person, programmed to release the drug in a pulse which ends a pre-set time before the person is expected to stop inhaling. In doing so, a minimum residence time within the lungs is created, and drug treatment time can be reduced. A corresponding method of controlling a drug delivery apparatus comprises the step of controlling the apparatus to release the drug in aerosolized form into the inhaled airstream of a person in a pulse which ends a pre-set time before the person is expected to stop inhaling.

  • Patent number: 8371299
    Abstract: The delivery of a medicament to a mechanically ventilated patient may include the steps of delivering a respiratory maneuver to such a patient, monitoring the physiological effects of the respiratory maneuver on such patient, automatically establishing an adjustment to the respiratory maneuver in response to the monitored physiological effects, and delivering the adjusted respiratory maneuver to such a patient.

  • Patent number: 8261738
    Abstract: An aerosol drug delivery apparatus is provided. The apparatus may include a reservoir constructed to contain a predetermined dose of a liquid drug, an aerosol generator in communication with the reservoir, and a power source arranged to deliver power to the aerosol generator in order to produce an aerosolized form of the dose that can be administered to a patient. The apparatus may maintain consistent aerosol drug delivery treatments, for example, by way of a breath measuring mechanism that monitors the patient's breathing pattern during the administration of the dose and a controller configured to vary the power level at which the power source during the administration of the dose based on the monitored breathing pattern.

  • Patent number: 7748382
    Abstract: Signals may be generated in a drug delivering apparatus through which a person inhales to generate a inhaled airstream to signal to the person to cease inhalation after a pre-set period of time has elapsed from detection of the commencement breathing by that person. The pre-set period of time for subsequent inhalations is adjusted depending on the time the person takes to stop inhaling after being signalled.

  • Publication number: 20080257337
    Abstract: A method for delivering a medicament to a mechanically ventilated patient receiving a flow of breathing gas comprises delivering a respiratory maneuver to such a patient, monitoring the physiological effects of the respiratory maneuver on such patient, automatically establishing an optimized respiratory maneuver in response to the monitored physiological effects, and delivering the optimized respiratory maneuver to such a patient. A system for delivering an aerosolized medicament to a ventilated patient is also provided.
