AI Technical Summary
Existing ventilation tubes can easily lead to tracheal necrosis and accidental ingestion of stomach acid or saliva when the trachea is sealed, affecting the patient's breathing.
A smart ventilation tube was designed, equipped with a body fluid detection sensor and a pump system. By detecting the type and concentration of body fluid above the air bag, the pump is automatically controlled to flush and pump water to clean the outer wall of the tube and prevent body fluid from entering the trachea.
It effectively prevents bodily fluids from entering the trachea, reduces tracheal damage and breathing difficulties, and improves the patient's respiratory safety.
