Delivering variable positive airway pressure depending on awake state and sleep disordered breathing
Patent number: 10953171Abstract: Positive airway pressure (“PAP”) systems and methods are provided which supply a patient with a range of pressures for treatment when the patient is determined to be asleep, and an awake pressure for use when the patient is determined to be awake, the awake pressure configured for the comfort of the patient. The awake pressure is configured to be lower than the lower bound of the pressure range and can be a therapeutic or sub-therapeutic pressure. The PAP systems and methods disclosed herein advantageously allow for the pressure range to be tailored for effective treatment of sleep disordered breathing while allowing the awake pressure to be set for the comfort of the patient. This can advantageously increase both the efficacy of the treatment of SDB and patient compliance with the treatment.Type: GrantFiled: March 27, 2015Date of Patent: March 23, 2021Assignee: Fisher & Paykel Healthcare LimitedInventors: Andrew Gordon Gerred, David Robin Whiting -

Patent number: 10912900Abstract: Embodiments are directed to a portable vaporization device whereby the vaporization device extracts active compounds from various liquids, fluids, oils, and waxes for inhalation and may heat up any desired amount of a vaporizable substance. The vaporization device has a button that ignites the liquefied gas to produce a flame. The vaporization device has a button to start the feeding mechanism, which pushes the vaporizable substance against a tube that the flame is heating to turn the vaporizable substance more viscous where it then runs down the tube into a series of wires, further heating the vaporizable substance, turning the vaporizable substance into vapor. The dosage of the vaporization device may be set to provide a lower amount of vapor to a greater amount of vapor. The button may be pushed to produce as much vapor as desired.Type: GrantFiled: March 23, 2018Date of Patent: February 9, 2021Inventor: Sean Avots

Patent number: 10905834Abstract: An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 ?m.Type: GrantFiled: January 18, 2018Date of Patent: February 2, 2021Assignee: Trudell Medical InternationalInventors: Bryan Finlay, Michael Nuttall, Brandon Coultes, Mark Nagel, Mark Pickard
