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

Publication number: 20230321377Abstract: Over-enthalpy conditions when using a respiratory and/or surgical humidifier system can be prevented. A heating element power in an inspiratory conduit can be limited based at least in part on one or more parameters of the gases flow, and/or on an ambient temperature. The limit on the heating element power in the inspiratory conduit can be achieved using a processor and/or protection circuit(s) located outside the processor. For example, the system can use the processor to determine and/or apply the limit as a level of protection and use the protection circuit(s) as another level of protection.Type: ApplicationFiled: August 13, 2021Publication date: October 12, 2023Inventors: Yintao Yu, Wenjie Robin Liang

Publication number: 20230166064Abstract: An improved system and method of controlling the operation of a respiratory or surgical humidifier system that can provide humidified gases of substantially constant humidity in dependence upon only one monitored variable, being signals received from a temperature sensor. A power controller can be configured to control a level of power supplied to a heater plate in dependence upon heater plate temperature and a humidity profile so as to drive an operating point of the humidifier towards the humidity profile. The rate of change of a heater plate temperature setpoint can be variably controlled in dependence upon a heater plate temperature setpoint and heater plate temperature.Type: ApplicationFiled: April 28, 2021Publication date: June 1, 2023Inventors: Wenjie Robin LIANG, Yintao YU

Publication number: 20230065301Abstract: An improved system and method of monitoring the operation of a respiratory or surgical humidifier system. A controllable load can be connected across output terminals to a tube heating element to test the operation of a tube heating element supply circuit. A range of tests may be performed by controlling the state of one or more components and monitoring one or more sensors. Tests may be performed either during or not during therapy and either with a gas supply tube connected or not. Transient currents may also be detected and the power supply to a tube heating element can be stopped where transient currents outside a permitted range are detected.Type: ApplicationFiled: February 3, 2021Publication date: March 2, 2023Inventors: Yintao Yu, Sinaa Alnashi, Wenjie Robin Liang, Jonathan Luke Hoi-Man Tsang

Publication number: 20230026603Abstract: A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.Type: ApplicationFiled: July 28, 2022Publication date: January 26, 2023Inventors: Andre Van Schalkwyk, Anthony James Newland, Rachael Glaves, Wenjie Robin Liang, Winnie Yong Jiang-Foo

Publication number: 20220273902Abstract: The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body. The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (for example, 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 may be employed for other medical uses.Type: ApplicationFiled: March 16, 2022Publication date: September 1, 2022Inventors: Anton Petrochenko, Wenjie Robin Liang, Paul James Tonkin
