Background
The information disclosed in the background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information constitutes prior art that is already known to a person of ordinary skill in the art.
The endotracheal intubation technique is a technique for inserting a special endotracheal tube into the trachea of a patient through the oral cavity or the nasal cavity, is used for anaesthetizing and rescuing the patient, and is also the most reliable means for keeping the upper respiratory tract unobstructed. A special catheter used in the endotracheal intubation is called an endotracheal tube, and the endotracheal tube is extremely important as a breathing passage for maintaining life of an operation anesthesia patient and a critically ill patient.
At present, the tracheal cannula is popularized and relatively mature clinically, but the tracheal cannula also has the problem of inconvenient operation. At present, most of common clinical tracheal cannulas are reinforced tracheal cannulas, and after the common clinical tracheal cannulas are inserted into a glottis to a certain depth under the assistance of a visible laryngoscope, plastic tooth pads are embedded between upper and lower incisors and are bound with the tracheal cannulas, and then the two are fixed in an oral cavity together through the tooth pads with threads or adhesive tapes; or the tracheal cannula is directly wound by the adhesive tape without a bite block to be fixed. In the clinical practical operation process, the tracheal cannula is a circular tube with a certain radian and is directly placed between the upper teeth and the lower teeth for fixation, because the friction force between the teeth and the tube is small, and the tracheal cannula is easy to slide and deviates to one side or continuously drops outwards by the pushing of the tongue though being fixed by an adhesive tape; if the trachea cannula is fixed with the bite-block, the bite-block is easy to cause the damage of teeth because the bite-block is mostly made of hard plastics. In addition, when some patients have teeth falling off (particularly upper and lower incisors), the teeth can directly contact with the gingiva when being fixed by the tooth pad, and the gingiva is easily damaged; meanwhile, when some critical patients are rescued by trachea intubation, if the bite block is needed, the tracheal catheter is fixed by one more step, which affects the cardio-pulmonary resuscitation of the patients.
