AI Technical Summary
Conventional humidifiers lack effective control strategies to maintain desired target humidity levels in respiratory and surgical applications, often requiring multiple sensors and being prone to instability during transient events, especially when handling varying flow rates and ambient temperatures.
A respiratory or surgical humidifier system that continuously controls heater plate power based on temperature signals from a heat transfer body sensor, without the need for additional gas flow sensors, allowing for stable humidity maintenance across varying conditions and transient events.
Ensures consistent humidity levels, reduces condensation, and maintains stable operation across different breathing circuits and ambient temperatures, providing safe and efficient humidification without additional sensors.
