2. the endotracheal tube is generally disposable, the metal tube is costly and results in waste of metal material;

3. if the metal tube is not used, the light bar cannot be used, so that whether the inserting position of the trachea cannula is suitable for establishing the airway cannot be judged after the metal tube is pulled out of the trachea cannula.

In view of this, in a first embodiment of the present application, there is provided a medical endotracheal intubation device, as shown in fig. 1 to 3, including:

a closing mechanism 2 disposed on the outer wall of the tube body 1, the closing mechanism 2 being expandable to close a space between the respiratory tract and the outer wall of the tube body 1;

and the light source module 3 is arranged on the tube body 1 and is used for indicating the position of the head end of the tube body 1 and/or the position of the closing mechanism 2 in the respiratory tract.

Wherein, the head end position of the trachea cannula body 1 indicates whether the trachea cannula is shifted, and the position of the closing mechanism 2 can inform medical personnel whether the airway established by the current trachea cannula is stable. It should be noted that, since the distance between the closing mechanism 2 and the head end of the tube body 1 is relatively fixed, the light source module 3 only needs to indicate the position of one of the two, so as to satisfy the object of the present invention.

The closing mechanism 2 may be an inflatable air bag or a water bag capable of being filled with water, and the specific choice thereof is not limited in the present application.
