Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in fig. 1 to 3, the present embodiment provides an endotracheal tube including a tube main body 1 and an intraoral fixture 2; the intraoral fixing device 2 comprises a sliding connector 201, a fixing piece 202, a clamping strip 203, a clamping block 204 and a limiting groove 205;
the fixing piece 202 is fixed on the tracheal catheter, and the sliding connecting piece 201 is connected with the catheter main body 1 on one side in a sliding way; one end of the clamping strip 203 is bonded with the sliding connecting piece 201, and the other end is bonded with the fixing piece 202; a first fixture block 204 is arranged at the position of the catheter main body 1 close to the fixing element 202, and a corresponding limiting groove 205 matched with the first fixture block 204 is arranged on the sliding connecting element 201; a pull rope 3 is provided on the other side of the sliding connector 201.
