AI Technical Summary
Technical Problem
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.
Method used
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.
Benefits of technology
It effectively prevents bodily fluids from entering the trachea, reduces tracheal damage and breathing difficulties, and improves the patient's respiratory safety.

Abstract
This invention provides an intelligent ventilation tube with an automatic cleaning function, comprising an inflation port, an inflation tube, an air bladder, and a tube body; the air bladder is disposed near the second end of the tube body; one end of the inflation tube communicates with the air bladder, and the other end communicates with the inflation port; it also includes: a connector, a main controller, a body fluid detection sensor, a pump, a flushing pipe, and a draining pipe; the connector is disposed on the outside of the tube body; the body fluid sensor is exposed on the outside of the tube body, near the air bladder; the main controller is disposed within the connector; one end of the flushing pipe and the draining pipe is fixed within the connector, and the other end extends above the air bladder; the pump is connected to one end of the flushing pipe and the draining pipe, respectively, and both the pump and the body fluid sensor are electrically connected to the main controller. This invention automatically cleanses these body fluids by controlling the operation of the pump, thus preventing body fluids from unintentionally flowing into the esophagus and entering the trachea and lungs.
