Patent number: 11957844Abstract: The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.Type: GrantFiled: April 27, 2023Date of Patent: April 16, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dean Antony Barker, Jack Che-Wei Hsu, Jae Chul Han

Patent number: 11951257Abstract: A patient interface includes a frame, an inflatable seal, and a deformable insert. The frame includes an outer portion, an inner portion, and an opening extending therebetween. The inflatable seal is secured to the inner portion of the frame. The inflatable seal defines an internal volume and has at least one aperture. The deformable insert includes an outer surface, an inner surface and a passageway extending therebetween. The deformable insert is positioned within the internal volume of the seal and aligned with at least a portion of the frame inner portion. The passageway is aligned with the frame opening to define a gas flow path from the frame outer portion to the at least one aperture of the seal.Type: GrantFiled: February 4, 2021Date of Patent: April 9, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Silas Sao Jin Siew, Andrew Paul Maxwell Salmon, Wen Dong Huang

Patent number: 11918739Abstract: A breathing gases supply apparatus 1 can comprise a blower 103/105 and breathing circuit for delivering breathing gases to a patient. The apparatus also can comprise a first controller 109, the controller 109 configured to receive input from at least one sensor 110-112 indicative of patient breathing, and a transmitter 201 configured to communicate with the controller 109 and transmit control signals to an electronic apparatus 203. The controller 109 can be configured to determine sleep in a patient based on the occurrence of a breathing pattern indicative of sleep, detected from the input received from the sensor 110-112 and upon determining sleep, operate the transmitter 201 to send a control signal to control an electronic apparatus 203.Type: GrantFiled: October 1, 2020Date of Patent: March 5, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: James Malcolm Thompson, Fiona Elizabeth Cresswell, Donald Roy Kuriger

Patent number: 11918745Abstract: Medical tubes and methods of manufacturing medical tubes are disclosed, such as in positive airway pressure (PAP), respirator, anaesthesia, ventilator, and insufflation systems. The tube may be a composite structure made of two or more distinct components spirally wound to form an elongate tube. One of the components may be a spirally wound elongate hollow body, and the other component an elongate structural component spirally wound between turns of the spirally wound hollow body. Alternatively, the tube need not be made from distinct components. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or have other medical uses.Type: GrantFiled: May 25, 2018Date of Patent: March 5, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Gareth James Hobbs, Layton Robert Hern, Kiel Anthony McCool, Elmo Benson Stoks

Patent number: 11918748Abstract: A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.Type: GrantFiled: March 15, 2021Date of Patent: March 5, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dean Antony Barker, Mikael Douglas Stewart, Peter Geoffrey Hawkins, Kevin Peter O'Donnell, Russel William Burgess

Patent number: 11911564Abstract: The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermistor), of gases flowing through a heated tube, supplying gases to a patient, which utilises the heating wire within the tube.Type: GrantFiled: April 26, 2021Date of Patent: February 27, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Matthew Jon Payton, Kevin Peter O'Donnell, Andrew Baden Clark, Christopher Simon James Quill, Peter Geoffrey Hawkins
