Patent number: 11116931Abstract: A pressure support system for delivering a flow of breathing gas to an airway of a patient includes a base unit structured to generate the flow of breathing gas and including a heating control unit, a conduit coupled to the base unit and structured to carry the flow of breathing gas, a thermistor disposed in the conduit, and first and second resistive wires extending along the conduit from the base unit to the thermistor. The heating control unit is structured to selectively operate in a first mode to heat the conduit using the first and second resistive wires and a second mode to sense a temperature of airflow in the conduit with the thermistor via the first and second resistive wires.Type: GrantFiled: December 14, 2018Date of Patent: September 14, 2021Assignee: Koninklijke Philips N.V.Inventors: Michael B. Knepper, Steven Adam Kimmel

Patent number: 10226590Abstract: A pressure support device implements compensation for variations in air density of its operating environment. A pressurized flow of breathable gas is generated for delivery to the airway of a subject. One or more parameters associated with the ambient environment of the pressure support device are determined. These parameters can include one or more of an ambient barometric air pressure, an ambient air temperature, or ambient air humidity. In some embodiments, one or more assumed parameters associated with the ambient environment of the pressure support device are determined based on typical sleeping conditions of the subject. An ambient air density of the ambient environment of the pressure support device is estimated based on one or more of the parameters and/or assumed parameters. A flow rate of the pressurized flow of breathable gas is adjusted based on the estimated ambient air density of the ambient environment of the pressure support device.Type: GrantFiled: February 25, 2013Date of Patent: March 12, 2019Assignee: Koninklijke Philips N.V.Inventor: Steven Adam Kimmel

Patent number: 9983039Abstract: A device (12) that uses a temperature coefficient pre-calibrated for the device for measuring a flow within the device. The device includes a differential pressure sensor (80) configured to generate a differential pressure signal responsive to a differential pressure within a flow path (16) and a temperature sensor configured to sense a temperature near the differential pressure sensor. A differential amplifier amplifies differential pressure signals from the differential pressure sensor. A processor receives signals from the differential pressure sensor, amplified signals from the differential amplifier, and signals from the temperature sensor. The amplified signals are corrected based upon at least a predetermined temperature coefficient, and the processor calculates a flow rate based on the corrected representation of the differential pressure.Type: GrantFiled: October 15, 2010Date of Patent: May 29, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alain-Jean Delache, Steven Adam Kimmel

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: 20120239336Abstract: A method for calibrating a temperature compensation coefficient for a device (12) that utilizes flow. The device includes a flow path (16) and a flow restriction portion (14) in the flow path to create a pressure differential in the flow path. The method includes calculating a temperature compensation coefficient and obtaining a first temperature and a first differential pressure reading at a first time period before flow is generated through the device, and obtaining a second temperature and a second differential pressure reading at a second time period after flow is generated through the device. The method further includes obtaining a compensated differential pressure value based on the temperature compensation coefficient, the measured first temperature, the first differential pressure reading, the measured second temperature, and the second differential pressure reading. The method also includes obtaining the flow within the flow path as a function of the compensated differential pressure value.Type: ApplicationFiled: October 15, 2010Publication date: September 20, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Alain-Jean Delache, Steven Adam Kimmel
