Patent number: 12263303Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.Type: GrantFiled: March 27, 2020Date of Patent: April 1, 2025Assignee: Fisher & Paykel Healthcare LimitedInventors: Ivan Chih-Fan Teng, Po-Yen Liu, Ho Shing Lo, Oliver Samuel Steiner, Peter Alan Seekup

Patent number: 12233212Abstract: Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.Type: GrantFiled: February 18, 2021Date of Patent: February 25, 2025Assignee: Fisher & Paykel Healthcare LimitedInventors: Po-Yen Liu, Peter Alan Seekup, Anthony James Newland, Malcolm David Smith, Ping Si, Helgard Oosthuysen, Matthew Robert Wilson, Ian Lee Wai Kwan, Sinaa Alnashi, Paul James Tonkin, Kiel Anthony McCool, David Robert Kemps, Yayi Lin, Callum McDonald Ross, David John Sims

Patent number: 12208204Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.Type: GrantFiled: April 6, 2023Date of Patent: January 28, 2025Assignee: Fisher & Paykel Healthcare LimitedInventors: Po-Yen Liu, Ivan Chih-Fan Teng, Peter Alan Seekup, Daniel John Smith, Ho Shing Lo
