Patent number: 10092712Abstract: A system for delivery of aerosol therapy to spontaneously breathing patients comprises a housing which defines a chamber. The housing has a base, a top and a main body extending between the base and the top. An ambient air inlet is located adjacent to the base and is normally closed by an inlet valve. The housing also has a patient port for receiving a mouthpiece or a face mask. The mouthpiece has an exhaust outlet closed by an exhaust valve. Similarly, the face mask has an exhaust outlet closed by an exhaust valve. Exhaled air is exhausted through the valves and to prevent recirculation through the chamber which would adversely affect dose efficiencies. The housing also has an aerosol port for receiving a vibrating mesh aerosol generating device. The aerosol port is located in a side of the main body of the housing for delivery of aerosol into the chamber between the inlet valve and the patient port.Type: GrantFiled: October 31, 2014Date of Patent: October 9, 2018Assignee: Stamford Devices LimitedInventors: Patrick Joseph Power, Jimmy Eaton-Evans

Patent number: 10058664Abstract: A device for providing a high frequency ventilation to a patient that includes a pressure generating system that delivers a flow of breathing gas to the patient, where the flow has a first and second positive pressure levels that alternate with one another in a plurality of cycles in the flow so as to have a frequency and an amplitude. The flow generates a mean airway pressure. A controller, coupled to the pressure generating system, is configured to make a determination, as to a spontaneous breathing, or an attempt, by the patient, or a change in a user settings by a user, and in response adjusts the mean airway pressure, modulates the frequency and a duty cycle of the flow, or modulates a level of the flow and the amplitude of the flow, or two or more flows.Type: GrantFiled: December 1, 2010Date of Patent: August 28, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gardner Kimm, Smita Garde, Mabini Arcilla

Patent number: 10046125Abstract: Systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors. The long term sensitivity drift of catalytic type electrochemical gas sensors can be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can reduce the amount of times the sensor goes offline. Systems and methods may factor in actions occurring at the delivery system and/or aspects of the surrounding environment, prior to performing a baseline calibration, and may postpone the calibration and/or rejected using the sensor's output for the calibration.Type: GrantFiled: November 4, 2016Date of Patent: August 14, 2018Assignee: Mallinckrodt Hospital Products IP LimitedInventors: Craig R.
