Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an integrated device for mouth gag and fixation of intubation tube for patients with general anesthesia, critical illness and the like. BACKGROUND

[0002] Tracheal intubation is a method of placing a specially designed endotracheal tube through the oral or nasal cavity, 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] A dental pad is one of the tools used in oral tracheal intubation, and its functions include preventing the patient from biting the tracheal tube in the mouth, helping to fix the tracheal tube, preventing the tracheal tube from moving in the mouth, assisting in suctioning the oropharyngeal secretions, and assisting in inserting the tube into the oropharynx or stomach. One of the structures of the dental pad is that the dental pad body is placed between the upper and lower teeth of the patient to prevent the teeth from biting the tracheal tube, the long side on both sides of the main body is the lingual surface, the short side is the palatal surface, and the dental pad wings located on the outer edge of the upper and lower teeth are fixed to prevent the whole dental pad from moving, one dental pad card is placed on the left and right sides, the tracheal tube is placed in the dental pad card groove to fix the tube and prevent the tube from moving, and the dental pad and the tube are fixed by a fixing rope to prevent the tube from falling off and moving. Another structure of the dental pad is that a fixing bolt is used to fix the tracheal tube in the dental pad card, to prevent the tube from moving, a bite plate is placed between the upper and lower teeth of the patient to prevent the teeth from biting the tracheal tube, a fixing belt is used to prevent the dental pad and the tube from falling off and moving, and a tube card is used to facilitate the placement of the tube.

[0004] In summary, there are the following technical problems in the maintenance process of the safety and position of the intubation tube for patients with general anesthesia, critical illness and the like: in clinical work, the mouth of patients with general anesthesia and critical illness, especially those with oral intubation, needs to be kept open to maintain the normal function of the ventilator, but most existing medical units simply use a syringe, a cylindrical dental pad or other hard objects to replace the mouth gag to maintain the open state of the patient and the safety of the intubation tube, and the mouth gag is often placed in the anterior tooth area of the patient. Due to the particularity of the force direction in the anterior tooth area, the traditional syringe or dental pad can easily cause damage to the anterior teeth of the patient during the entire intubation treatment process.
