Background

Endotracheal intubation is one of the anesthesia procedures that require adequate oxygen supply to the patient with the aid of a ventilator or anesthesia machine. The use of such a breathing apparatus requires the insertion of an appliance called a tracheal tube through the patient's mouth and into the general trachea. The tracheal catheter has large lumen and thin wall, and is easy to bite the flat lumen to cause respiratory tract blockage and to be taken out of the body when the patient closes the teeth tightly. Since the tube inserting technology is used for general anesthesia, the tracheal catheter is fixed by a bite block. The bite-block made of rubber or metal is arranged at one side of the tracheal catheter in parallel, the tracheal catheter and the bite-block are stuck together by 2-3 adhesive tape strips with the length of 30 cm, and two ends of the adhesive tape are respectively stuck on cheeks at two sides of a patient.

But because the bite block is not sold as a finished product, the bite block is manufactured by an anesthesiologist. The tracheal catheter is fixed by the bite block, and if the bite block is short, the tracheal catheter is easy to slide into the throat of a patient to cause danger; some patients spit secretion and easily soak the adhesive plaster, so that the bite block and the tracheal catheter are separated from the body, when the catheter is too deep or too shallow and needs to be adjusted, the adhesive plaster which is stuck needs to be loosened, and the catheter is fixed again after being adjusted. The adhesive plaster is not firmly adhered when the quality is poor, the skin of a patient is easily adhered if the adhesive plaster is adhered or pulled to be too tight, and the zinc sulfide adhered on the tracheal catheter and the tooth pad after use is not easy to clean.

Therefore, how to design a device for assisting catheter fixation in general anesthesia becomes a problem to be solved currently.
