[0034] As shown in Figure 1 The first aspect of the embodiments of the present application proposes a tracheal tube, which comprises: a tube body 110, the tube body 110 is a hollow structure, a first gas conveying pipe 120 and a second gas conveying pipe 130 are arranged in the tube wall of the tube body 110; a fixed air bag 140 is arranged on the tube body 110, and the first gas conveying pipe 120 is communicated to the fixed air bag 140; an anti-burning air bag 150 is arranged on the tube body 110, and the second gas conveying pipe 130 is connected to the anti-burning air bag 150; and an anti-burning layer 160 is sleeved on the outer side of the anti-burning air bag 150.

[0035] The endotracheal tube includes a tube body 110, a fixation cuff 140, a burn-proof cuff 150, and a burn-proof layer 160. During use, the end with the fixation cuff 140 and burn-proof layer 160 is lowered into the patient's throat. The endotracheal tube is connected to a high-frequency ventilation ventilator. The fixation cuff 140 secures the position of the endotracheal tube. During use, firstly, the tube body 110 can be a flexible tube, allowing it to pass directly through the glottis, preventing airflow from affecting the stability of the surgical area tissue and ensuring operational stability and safety; secondly, the burn-proof layer 160... The endotracheal intubation device 150 can be positioned in the subglottic region. After the anti-burn balloon 150 is inflated, it directly blocks the trachea from the glottis, preventing CO2 laser damage to the subglottic trachea during surgery. Thirdly, the surface of the anti-burn balloon 150 is covered with a shrinkable flame-retardant anti-burn layer 160, which can prevent spontaneous combustion induced during CO2 laser surgery and thus prevent serious complications. Fourthly, the anti-burn balloon 150 and the anti-burn layer 160 facilitate complete sealing of the gap between the glottis and the airway, preventing bleeding and exudate from flowing into the airway during surgery and causing lung-related complications. Based on this, the endotracheal intubation provided in this embodiment makes the operation more convenient, with a lower probability of dangerous accidents and complications during laser surgery on the pharynx.

[0036] like Figure 1 As shown, in one feasible embodiment, the endotracheal cannula further includes an infusion tube 170, which passes through the hollow structure and connects to the anti-burn layer 160.

[0038] like Figure 1 As shown, in one feasible embodiment, the anti-burn layer 160 is made of absorbent cotton material.

[0039] In this technical solution, the material of the anti-burn layer 160 is further provided. The anti-burn layer 160 is made of absorbent cotton material, which has certain flame retardant properties and is easy to absorb liquid.

[0040] like Figure 1 As shown, in one feasible embodiment, the endotracheal tube further includes a first one-way valve 180 and a first observation cuff 190, which are disposed at the end of the first air supply tube 120. This arrangement makes the use of the endotracheal tube safer.

[0041] In a feasible implementation, the tracheal cannula further comprises: a second one-way valve 200 and a second observation balloon 210, which are arranged at the end of the second gas delivery tube 130. Such arrangement makes the use of the tracheal cannula safer.

[0042] In a feasible implementation, the anti-burning balloon 150 is at least two, and the anti-burning layer 160 is arranged on each of the anti-burning balloons 150. Such arrangement can flexibly arrange the positions of the anti-burning balloon 150 and the anti-burning layer 160 based on the surgical area and type, so that the surgery is safer.

[0043] In a feasible implementation, the anti-burning balloon 150 is movably arranged on the tube body 110. Such arrangement can flexibly arrange the positions of the anti-burning balloon 150 and the anti-burning layer 160 based on the surgical area and type, so that the surgery is safer.
