Patent number: 11202875Abstract: Systems and methods are configured to inexsufflate a subject and provide cough-by-cough feedback during treatment and/or therapy of the subject. Through sensors that are included in the systems, various gas and/or respiratory parameters maybe measured and/or determined in real-time, such as, for example, peak cough flow and/or inspiratory tidal volume.Type: GrantFiled: May 14, 2013Date of Patent: December 21, 2021Assignee: Koninklijke Philips N.V.Inventors: Michael Howard Kissel, April Stewart Nathan, Winslow Kevin Duff, Bernard F. Hete

Patent number: 11147938Abstract: A ventilator that is small, lightweight, and portable, yet capable of being quickly adapted to operate in a plurality of different modes and configurations to deliver a variety of therapies to a patent. A porting system having a plurality of sensors structured to monitor a number of parameters with respect to the flow of gas, and a number of porting blocks is used to reconfigure the ventilator so that it operates as a single-limb or dual limb ventilator. In the single-limb configuration, an active or passive exhaust assembly can be provided proximate to the patient. The ventilator is capable of operate in a volume or pressure support mode, even in a single-limb configuration. In addition, a power control mechanism controls the supply of power to the ventilator from an AC power source, a lead acid battery, an internal rechargeable battery pack, and a detachable battery pack.Type: GrantFiled: January 2, 2019Date of Patent: October 19, 2021Assignee: Koninklijke Philips N.V.Inventors: Winslow Kevin Duff, William Anthony Truschel, Mark Christopher McDermott, Cheryl Lin Needham, Christopher Wayne McDaniel, Ljubisa Milojevic, Ronald Cyprowski

Patent number: 10729864Abstract: A method of providing pressure support to a patient that includes determining a measure associated with an inspiratory time of the patient during therapy, delivering a flow of breathing gas to the patient at an inspiratory positive airway pressure (IPAP) level during at least a portion of an inspiratory phase of the patient, delivering the flow of breathing gas to the patient at an expiratory positive airway pressure (EPAP) level that is less than the IPAP level during at least a portion of an expiratory phase of the patient, and automatically setting a rise time associated with a transition from the EPAP level to the IPAP level based on the measure associated with the inspiratory time of the patient. Also provided is a pressure support system adapted to perform the method.Type: GrantFiled: January 29, 2018Date of Patent: August 4, 2020Assignee: Koninklijke Philips N.V.Inventors: Winslow Kevin Duff, Peter Douglas Hill

Patent number: 9713692Abstract: A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.Type: GrantFiled: March 16, 2015Date of Patent: July 25, 2017Assignee: RIC INVESTMENTS, LLCInventors: John Raymond Pujol, Patrick Truitt, Daniel R. Martin, Winslow Kevin Duff, Steven Adam Kimmel, Jeffrey Kepler, Peter Chi Fai Ho, Lance Ranard Busch, Jerome Matula, Jr., Drew A. Demangone, Anthony J. Bafile

Publication number: 20140076317Abstract: Provided are systems and methods for utilizing blood oxygenation information with respiratory therapy. These systems and methods may provide respiratory therapy to a patient (119), which may include providing a flow of gas to a patient via a patient interface. Blood oxygenation information for the patient is then obtained. The blood oxygenation information is then used to adjust the respiratory therapy, advance a diagnosis for the patient, or for other purposes.Type: ApplicationFiled: March 15, 2012Publication date: March 20, 2014Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Gary William Lotz, Elias George Diacopoulos, Douglas Mechlenburg, Winslow Kevin Duff
