(3) Beneficial effects

Compared with the prior art, the present invention provides a double-balloon tracheal intubation, which has the following beneficial effects:

1. For the double-balloon tracheal intubation, when the airbag a is attached to the user’s airbag, continue to inject gas into the airbag a. At this time, the excess gas will drive the moving plate to move upward, thereby driving the moving column to move upward, so as to insert In the inner ring of the annular airbag, so that the excess gas can enter the ventilation groove, and then enter the airbag b from the air outlet. When the injection of gas is stopped, the elastic force of the annular airbag b can push the moving column down and return to its original position , so as to prevent the airbag a from expanding too much and squeezing the user's trachea and damaging the user's trachea due to excessive force. It can also avoid the damage of the user's trachea caused by insufficient medical personnel injecting too much gas into the airbag a, thereby facilitating those who are inexperienced. It is used by medical staff who accurately inject the appropriate gas according to the size of the patient's airway.

2. With the double-balloon endotracheal intubation, when the gas in the airbag a is not sealed well or other reasons cause the gas in the airbag a to become less and cannot fit with the inner wall of the user's trachea, the gas in the airbag b will drive the baffle to Move down, so that the gas in the airbag b can enter the airbag a through the connecting tube, so that the gas can be added to the airbag a, so that the airbag a can be attached to the inner wall of the user's trachea, which can prevent the device from being damaged during use. Accidental leakage of gas from air bag a cannot support and block the patient's trachea.

3. The double-balloon tracheal intubation tube, after injecting gas through the balloon b, the gas in the balloon b will exert pressure on the medicine bag due to the toughness of the balloon b, thus helping the medicine in the medicine bag to enter the catheter through the annular channel , thereby improving the drug delivery effect.

4. The double balloon tracheal intubation, by putting the medicine used in the user's trachea into the medicine bag, the medicine will enter the catheter through the annular channel, and the air will flow in the catheter through the external device to help the user When breathing, the gas will drive the medicine into the user's trachea, so that the medicine can directly act on the user's trachea, which can improve the speed of the drug's effectiveness.

5. The double-balloon tracheal intubation enters the catheter through the four drug outlets through the drug, and the air flows through the catheter, which can drive the rotating blade to rotate, so that the liquid drug can be dispersed, so that the drug will It presents a mist shape, so that it is more convenient for the air to bring the drug into the user's trachea, and at the same time, it can help the drug evenly act on the inner wall of the user's trachea, thereby increasing the use efficiency of the drug.

6. The double-balloon tracheal intubation tube can keep the movable ring stable through two stable rings and two annular chutes, so that the stability of the rotating ring can be maintained through two connecting bars, so that the device can be kept running stably .

7. The double-balloon tracheal intubation tube blocks the four drug outlets through the initial moving ring, and the gas in the catheter moves from bottom to top, and the rotating blade can drive the rotating ring to rotate, so that it can be driven by two connecting bars. The movable ring rotates, so that it can drive the moving ring to move upwards, so that it can leak out of the medicine outlet, so that the medicine can enter the catheter, so that it can enter the user's trachea with the upward flowing air. When it moves down, it will drive the rotating blade to rotate in the opposite direction, so that the moving ring can be driven downward through the rotating tube, two connecting bars and the movable ring, so as to cover the drug outlet, which can prevent the drug from being released with the air. Leakage to the outside world, thereby avoiding the loss of the drug.

8. For the double-balloon endotracheal intubation, when the gas in the airbag b is insufficient to apply pressure to the medicine bag, the elastic force of the pressure spring can apply an upward force to the push ring, so that the push ring can exert pressure on the medicine bag, so that Just can assist medicine bag to discharge medicine.
