Patent number: 11980714Abstract: An improved system and method of determining a low water and/or water-out condition in a humidifier chamber of a respiratory or surgical humidifier system can use a specific frequency band to detect changes in a temperature of a heater plate. The temperature changes can correlate to the specific heat capacity value of the humidifier chamber. The low water and/or water-out detection process can be performed without having to determine the gases flow rate and/or can be run continuously. A heater plate assembly of the system can include a compliant insulation sheet to improve thermal coupling between the heating element and the top heating plate of the heater plate assembly, thereby improving the low water and/or water-out detection process.Type: GrantFiled: August 9, 2019Date of Patent: May 14, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Bhuvan Garg, Francis Glynn, Stephen David Evans, Wenjie Robin Liang, Yintao Yu, Logan Ross Andrew

Patent number: 11980713Abstract: Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia.Type: GrantFiled: July 5, 2022Date of Patent: May 14, 2024Assignee: FISHER & PAYKEL HEALTHCARE LIMITEDInventors: Craig Karl White, Alicia Jerram Hunter Evans, Matthew Jon Payton, Geraldine Frances Keogh, Nicholas Simon David Connolly, Anil Patel, Seyed Ahmad Reza Nouraei

Patent number: 11964104Abstract: There is provided a a respiratory gas delivery and sampling system, a gas sampling system, a gas sampling interface and a gas sampling tip that may be used to sample exhaled and/or expired gases from a patient, particularly from a patient who is apnoeic and/or who is receiving high flow respiratory therapy. The gas sampling system comprises a respiratory gas monitor in fluid communication with the gas sampling interface, which comprises the gas sampling tip of the invention. The gas sampling interface comprises a gas sampling conduit and the gas sampling tip is located at a free end of the conduit. The gas sampling interface may be configured to allow the gas sampling tip to be selectively positioned at or in the mouth or a nare of the patient's nose.Type: GrantFiled: October 16, 2017Date of Patent: April 23, 2024Assignee: FISHER & PAYKEL HEALTHCARE LIMITEDInventors: Kate Jayne Chilcott, Alicia Jerram Hunter Evans, Edward John Evans, Samantha Dale Oldfield, Nathan James Roa, Craig Karl White

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
