Publication number: 20190307978Abstract: 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: ApplicationFiled: October 11, 2017Publication date: October 10, 2019Inventors: Po-Yen Liu, Ivan Chih-Fan Teng, Peter Alan Seekup, Daniel John Smith, Ho Shing Lo

Publication number: 20190262560Abstract: The present disclosure 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: ApplicationFiled: July 19, 2017Publication date: August 29, 2019Inventors: Po-Yen LIU, Ivan Chih-Fan TENG, Stefan Leo VAN WORKUM, Oliver Samuel STEINER, Anthony James NEWLAND
