AI Technical Summary
Existing high-flow humidification therapy devices require nurses to manually adjust the water volume in the humidification tank, and are prone to triggering alarms due to failure to replenish water in time, which affects the humidification effect, increases the workload of nurses, and may endanger the patient's condition.
The liquid level sensing system, consisting of a float, connecting rod, and contact sensor, combined with a solenoid valve and control module, automatically adjusts the water volume in the humidification tank. When the liquid level changes, the float triggers different liquid level contacts, controlling the solenoid valve to open and replenish water. An alarm is triggered when the low liquid level contact is reached, thus achieving automatic water replenishment and fault detection.
It achieves automatic water replenishment without the need for manual control by nurses, improving work efficiency, ensuring airway humidification, reducing nurses' workload, avoiding alarms caused by insufficient water, and promoting patient recovery.
