the utility model discloses need pass through sterilization before using, after trachea cannula operation is accomplished, will the utility model discloses put into along the mouth, make its bow face towards the palate, the concave surface is towards the tongue body, after the adjustment rear position, hugs closely trachea cannula in its side depressed grains department, and the right side pulls out the fixed band and puts in the cheek, later will the utility model discloses it is fixed through the sticky tape with the trachea cannula pipe, passes through at last the utility model discloses a pressure-sensitive adhesive material of fixed band, will the utility model discloses with trachea cannula pipe monolithic stationary in people's face, prevent that trachea cannula pipe from shifting in the use. The patient's upper and lower teeth will then bite onto the cannula part.

The utility model has the advantages as follows:

1. the utility model discloses overall structure has the bending, agrees with human oral anatomy, can reduce the damage of inserting the in-process to oral structure, mucous membrane tissue during the use.

2. Corresponding instruments and catheters can be placed into the supporting component with the hollow structure, certain clinical use value is achieved, the supporting component has certain hardness, the trachea cannula catheter can be prevented from being damaged and bent by teeth or other oral cavity structures, and accordingly smoothness of an airway is guaranteed.

3. The peripheral sleeve part is made of soft materials, can play a role in buffering, prevents the injury of the relevant mucous membrane of the apparatus and the injury of teeth or other oral structures in the process of maintaining ventilation through the tracheal intubation, and reduces the incidence rate of complications after intubation, thereby reducing the pain and medical burden of patients.

4. The fixed band can help the intubate to be fixed in people's face to can be according to the fixed firm degree of pressure adjustment, also can prevent the damage of baffle structure that uses at present to lip and gum.

5. The utility model is disposable, can satisfy the disinfection and sterilization of the surgical operation standard, has light materials and low price, and can not increase the economic burden of patients.
