Excuse me, what is the blue thin tube with a balloon for tracheotomy and intubation? What's the role? And how to use it?

Check valves and indicator bubbles. One is the function of inflation, and the other can indicate the inflation degree of intubation cuff.

The blue thin tube part of the airbag is connected with the circular blue part, mainly to check whether the gas in the circular blue part leaks and the gas pressure in the circular blue part.

The purpose is to make there is no gap between tracheal intubation and patient's trachea, and there will be no air leakage when using invasive ventilator; After pumping, pinch the airbag with your hand to feel the pressure, neither too big nor too small, which is generally not needed for nursing patients. Specialist nurses also need to operate in hospitals.
