  • Patent number: 10449307
    Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

  • Patent number: 10307551
    Abstract: An inhaler is provided that includes a controller, a driver, an atomizer and one or more sensors for detecting information about a velocity of inhalation of a user of the inhaler. The controller is configured to dispense an inhalant from the inhaler during an inhalation of the user based on information about the velocity of inhalation of the user. Such information can include a duration of maximum inhalation velocity or an increase or maximum in the acceleration in inhalation velocity. Embodiments of the inhaler can be used to enhance the delivery of drugs and therapeutic agents for those patients having a weakened respiratory system who are unable to take a deep or full breadth, e.g., patients having asthma or COPD. Embodiments of the inhaler can be used to deliver a variety of drugs and therapeutic agents including agents for the treatment of asthma, diabetes, epilepsy and heart disease.

    Abstract: Methods and devices for creating a supersaturated liquid solution having dissolved gas with hyperbaric partial pressures and aerosolizing the supersaturated solution via a nebulizer. High partial pressures of the dissolved gas may be maintained before, during, and after the aerosolization process. Thus, the hyperbaric partial pressures may be retained in the aerosol particles even after the particles are exposed to ambient barometric pressure. The aerosolized particles may be inhaled to improve oxygenation and blood flow to the lung or alternatively, the aerosolized particles can be topically applied to accelerate wound healing. Nebulizers may produce aerosol particles in some embodiments have mass median aerodynamic diameters of between about 0.25 and about 5 microns, thereby allowing sufficient deposition in the lung parenchyma, proximal to alveoli.

  • Patent number: 7849852
    Abstract: A medical breathing assistance apparatus (20) for supplying pressurised gases to a patient is disclosed. The breathing assistance apparatus (20) comprises a heating chamber (29) and a pressure chamber (27) both adapted to contain water, and at least one pressure adjusting means (24,25,26). The pressure chamber (27) is connected to the heating chamber (29) and the pressure adjusting means (24,25,26) is located between the heating chamber (29) and a gases supplying means (23) supplying gas to both the pressure chamber (27) and heating chamber (29). The pressure adjusting means (24,25,26) is adapted to convert pressurised gases from the gases supply means (23) to two different pressures, one to each of the heating chamber (29) and the pressure chamber (27), so that water flows from said pressure chamber (27) to the heating chamber (29).

  • Patent number: 7832394
    Abstract: Containers for incrementally dispensing pressurized contents are described. The containers comprise a vessel suited to contain pressurized contents, a port integral with the vessel and through which pressurized contents contained in the vessel can be released from the vessel, preferably incrementally in approximately equal amounts, and a measuring device disposed in the vessel. The measuring device senses ambient conditions in the vessel and, directly or with other components, indicates, for example, the amount of pressurized contents remaining in the vessel and displaying it to an observer; methods for comparing the amount of contents actually released from the vessel compared to a theoretical constant; and methods for time logging (alone or in conjunction with the logging of other data) the actuation of the dispensing valve for comparison to a prescribed method. Devices (including metered dose inhalers) for incrementally dispensing pressurized contents from such containers are also described.

  • Patent number: 7775211
    Abstract: The disclosed apparatus, systems and methods are effective in treating snoring behavior. Exemplary embodiments of the disclosed treatment apparatus include a mouthpiece, a first chamber in communication with the mouthpiece, and a displaceable member mounted with respect to the first chamber for applying a resistive force as gas is withdrawn from the first chamber. A second, substantially airtight chamber is generally defined on the opposite side of the displaceable member. The evacuation force required to deflect, deform or otherwise is increased due to the force required to displace the displaceable member positioned within the disclosed treatment apparatus. In exemplary embodiments of the disclosed apparatus, the displaceable member may take the form of a flexible membrane, piston or diaphragm that is mounted with respect to the inner wall of the first chamber or the second chamber. Use of the treatment apparatus is effective in reducing and/or eliminating snoring behavior for extended periods.

  • Patent number: 7607430
    Abstract: A method of coupling the upper and lower section of a humidifier container used to humidify oxygen gas, using magnetic coupling means. A series of corresponding magnets around the container, located externally to the device or internally, secure the lower part or vessel to the upper part or cap. Using magnets opposing an attracted metal may he used in lieu of corresponding magnet to magnet attraction which requires the poles of the magnets be oriented with their poles to attract each other.

  • Patent number: 7472705
    Abstract: A method and apparatus for delivering a medicine to a patient via the patient's respiratory system with control and efficiency. A nebulization catheter is positioned in the patient's respiratory system so that a distal end of the nebulization catheter is in the respiratory system and a proximal end is outside the body. In a first aspect, the nebulization catheter may be used in conjunction with an endotracheal tube and preferably is removable from the endotracheal tube. The nebulization catheter conveys medicine in liquid form to the distal end at which location the medicine is nebulized by a pressurized gas or other nebulizing mechanism. The nebulized medicine is conveyed to the patient's lungs by the patient's respiration which may be assisted by a ventilator. By producing the aerosol of the liquid medicine at a location inside the patient's respiratory system, the nebulizing catheter provides for increased efficiency and control of the dosage of medicine being delivered.

  • Patent number: 7461649
    Abstract: An inhaler comprising a compressed gas, such as Heliox gas is provided. The disclosed inhaler includes a first chamber containing a compressed gas which is in communication with an equalization chamber having pressure lower than the pressure of the gas in the first chamber. The inhaler also includes a drug storage chamber which is detachably coupled to the equalization chamber and operable such that a portion of the compressed gas from the equalization chamber fluidizes and aerosolizes the drug to produce a drug cloud. The drug cloud is directed into a spacer where it can be inhaled by a user.
