Publication number: 20230347097Abstract: A system is provided for delivering gas to a patient during a medical procedure. The system comprises a heater arranged to heat at least one of the gas and a humidification liquid. The system comprises a controller arranged to control the system according to a first mode during delivery of a first flow rate of gas and a second mode during delivery of a second flow rate of gas. The controller monitors an electrical characteristic of the heater to select the mode of operation and/or to determine an operating state of the system.Type: ApplicationFiled: May 4, 2023Publication date: November 2, 2023Inventors: Ali Ghalib Abdul Rahman Ghalib, Lina Tessy, Wisnu Arya Surendra, Jessica Kristen Chan, Joseph Patrick Walter Strevens, Monika Baumann

Publication number: 20220008681Abstract: Some embodiments provide for humidifier control systems and methods configured to adjust power to a heater plate in a surgical humidifier to account for changes in flow rate to provide a consistent output, to provide functionality for different modes of use, and to provide accurate control over temperature and/or humidity at relatively low flows. The humidifier control system can receive a flow rate reading and determine a power requirement corresponding to the received flow rate reading, wherein the power requirement is one of a plurality of set points which correspond to ranges of flow rates. The humidifier control system can determine a mode of use based at least in part on the flow rate reading. The humidifier control system can provide electrical power to the heater plate according to the power requirement and/or the mode of use.Type: ApplicationFiled: September 23, 2021Publication date: January 13, 2022Inventors: Ali Ghalib Abdul Rahman Ghalib, Lina Tessy, Joseph Patrick Walter Strevens, Paul David Phillips
