Patent number: 10974000Abstract: Methods and apparatus treat a respiratory disorder. For example, a pressure generator supplies a flow of air at positive pressure to a patient's airway through a patient interface.

A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.Type: GrantFiled: December 8, 2017Date of Patent: November 3, 2020Assignee: PHYSIO-CONTROL, INC.Inventor: Fred William Chapman

Patent number: 10821247Abstract: A ventilator (1) determines states with cough attacks and an operating method for a ventilator determines cough attacks. It is determined on the basis of pressure measured values (13, 21, 19) and flow measured values (11, 15, 17) whether consecutive elevations of an airway pressure in a ventilator (1) are due to one cough event or due to a plurality of cough events. A plurality of cough events indicates a state of a cough attack. An output (41, 42, 44) of a warning (44) or alarm (42) is issued indicating the state.Type: GrantFiled: November 6, 2017Date of Patent: November 3, 2020Assignee: Drägerwerk AG & Co.

Patent number: 10799656Abstract: A flow of breathable gas is delivered to a subject through a patient interface assembly. An enhanced technique for determining whether the airway of subject is disengaged from the patient interface assembly. A model that provides predicted values of a dynamic property of the flow of breathable gas is fit to measured values of the dynamic property. The model and/or the fit of the predicted values to the measured values are then analyzed to determine whether or not the airway of the subject is disengaged from the patient interface assembly. This provide enhanced determination of these conditions even in implementations in which a restrictive patient interface assembly is used.Type: GrantFiled: August 13, 2013Date of Patent: October 13, 2020Assignee: Koninklijke Philips N.V.Inventors: Nathan John Berry Ann, William Anthony Truschel

Patent number: 10782708Abstract: Provided is an automatic shutoff continuous positive air pressure (CPAP) system. The automatic shutoff CPAP system includes an air pump and a processor operably connected to a sensor disposed in headgear. The processor monitors data generated from the sensor. The processor compares the generated data from the sensor to a shutoff threshold. The processor determines that the headgear has been pulled away from a face of a user when the generated data satisfies the shutoff threshold. The processor deactivates the air pump of the CPAP system in response to determining the air mask has been pulled away from the face of the user.Type: GrantFiled: November 7, 2018Date of Patent: September 22, 2020Assignee: International Business Machines CorporationInventor: Dante Togliatti

Patent number: 10758157Abstract: This disclosure relates to a system configured to detect the presence of secretions in a subject's airway during respiratory therapy. The system can determine whether the subject requires airway clearance. A pressure generator generates a pressurized flow of breathable gas. Sensors generate output signals relating to one or more gas parameters of the pressurized flow of breathable gas. The system can determine a first parameter that is an indication of the volume of breathable gas within the airway of the subject and a time derivative of the first gas parameter to generate a plot of these parameters. The plot includes a perimeter and an area that can be used to determine whether to effectuate initiation of airway clearance based on a complete breathing cycle that includes at least one inhalation and exhalation.Type: GrantFiled: October 13, 2015Date of Patent: September 1, 2020Assignee: Koninklijke Philips N.V.Inventor: Bernard F.

Patent number: 10758156Abstract: An improved device for monitoring respiration or other vital signs of a user using one or more sensors. The invention may be worn within the mouth of the user to allow more accurate, direct, and fast measurements. The invention may also include a distribution mechanism that may be used to administer a substance such as medication. The substance may be administered in response to data collected by one or more of the sensors in the device and/or in response to data received from another device.Type: GrantFiled: February 25, 2019Date of Patent: September 1, 2020Assignee: Child Mind Institute, Inc.Inventor: Curtis P.

Patent number: 10758691Abstract: An additive gas delivery apparatus, system and method for delivery of additive gas, such as nitric oxide [NO], to a patient use a control computer configured to determine if a monitored parameter indicates that a patient is connected to the additive gas delivery apparatus, determine if the additive gas delivery apparatus is in a passive state in which it does not deliver additive gas, and activate an alarm if the additive gas delivery apparatus is in said passive state when the monitored parameter indicates that a patient is connected to the additive gas deliver apparatus. The alarm serves to notify the user of undesired non-delivery of additive gas, and so serves to improve safety in additive gas delivery systems.Type: GrantFiled: June 18, 2014Date of Patent: September 1, 2020Assignee: Maquet Critical Care ABInventor: Leif Lindkvist

Patent number: 10751490Abstract: Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators.Type: GrantFiled: August 12, 2016Date of Patent: August 25, 2020Assignee: ResMed Pty LtdInventors: Dion Charles Chewe Martin, Clancy John Dennis, Benjamin John Leavens, Etienne Veschambre, Stuart Wishart

Patent number: 10688263Abstract: A servoventilator control slowly changes the target ventilation over a period of time, according to a preprogrammed schedule adapted to be set by the physician. Preferably, the target ventilation stays constant at an initial target ventilation for an initial hold time, and then increases at a constant rate until it reaches a final target ventilation, whereupon it stays constant thereafter. If the pressure support level is too high, possibly indicating glottic or upper airway closure, the rate of increase of target ventilation may be lowered or the final target ventilation not reached.Type: GrantFiled: October 21, 2015Date of Patent: June 23, 2020Assignee: ResMed Pty LtdInventor: David John Bassin
