Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tracheal intubation, in particular to a tracheal intubation fixing device. BACKGROUND

[0002] Tracheal intubation is a method of placing a specially designed endotracheal tube through the mouth or nose, through the glottis into the trachea or bronchus, to provide the best conditions for airway patency, ventilation and oxygen supply, and respiratory tract suction, and is an important measure for rescuing patients with respiratory dysfunction.

[0003] Tracheal tube prolapse is one of the more serious complications in mechanical ventilation. Tracheal tube prolapse may be self-extubation by the patient or accidental extubation during medical care. Once the tracheal tube prolapses, it will cause further harm to the patient, and if not treated in time, it can lead to acute hypoxia, even suffocation and death.

[0004] After successful tracheal intubation, the tracheal tube must be kept in a fixed position without displacement or falling off. The current method for fixing the tracheal tube is to fix the dental pad and the tracheal tube with adhesive tape and then directly paste them to the patient's cheeks. Since the fixing method is simple, it has many drawbacks. The use of adhesive tape often makes the patient feel uncomfortable, irritates the skin and causes inflammation or skin ulceration, and the adhesive property of the adhesive tape is easily weakened or lost, resulting in loose connection and easy dislocation of the tube. SUMMARY
