Description

A kind of anti-bite flat tracheal intubation

technical field

The utility model belongs to the technical field of medical devices and relates to a tracheal intubation, in particular to an anti-bite flattened tracheal intubation.

Background technique

Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchi through the glottis to provide the best conditions for airway patency, ventilation and oxygen supply, and airway suction. Ventilator-assisted respiration may be required in cases of coma, pulmonary infection, and severe pulmonary disease. It is one of the indispensable and important measures to rescue patients with respiratory dysfunction.

At present, when the conventional ventilator assists the patient to breathe, the endotracheal tube needs to be inserted into the patient's trachea. Since the endotracheal tube is relatively soft, the patient will bite his teeth due to voluntary or involuntary factors during use. Endotracheal intubation, leading to blockage of the endotracheal intubation, making the patient unable to breathe effectively, and in severe cases there may be a risk of suffocation.

A common clinical practice is to insert a tracheal intubation in the patient's mouth, and then put a hard tooth pad to prevent the patient from biting the tube. This approach requires the patient to open the mouth wide, which reduces patient comfort, squeezes the lips and increases the risk of lip bleeding, and inability to properly clean the mouth increases the risk of airway infection.

For patients using tracheal intubation, the secretions in the oral cavity have certain difficulties in swallowing. When the patient has too much oral secretions, we should use a suction tube to put it into the oral cavity to suck out the secretions in the oral cavity.

Utility model content

The utility model provides an anti-bite-flat tracheal intubation in view of the deficiencies of the prior art, adopts the cooperation of an adjustable tooth pad and the intubation tube, and can adjust the position of the tooth pad according to the patient's condition, which is convenient for medical staff to adjust, and The groove allows the patient to rest their teeth during occlusion, improving the comfort of the patient during intubation.

The technical scheme adopted by the utility model:

An anti-biting tracheal intubation tube is composed of an intubation tube, a tooth pad, an inflation tube and a suction tube. The intubation tube is made of soft material, and the intubation tube is provided with threads. There is a through port corresponding to the cannula, a thread is arranged in the through port, the tooth pad is movably connected with the cannula through the thread, and the position of the tooth pad on the cannula can be adjusted through the thread, on the left and right side of the tooth pad. There are perforations on both sides, and binding ropes are set on the perforations. When the intubation tube is inserted into the patient’s trachea, the intubation can be fixed through the patient’s neck through the binding rope. There are fixed openings on the left and right sides of the tooth pad for inflation. The tube and the suction tube are arranged on the intubation tube, the inflation tube is connected to the intubation tube through the left fixed port, and is connected to the tube wall of the intubation tube. There is a balloon on it, and the balloon can be inflated through the wall of the intubation tube through the inflatable tube, so that the balloon can be inflated. It expands and fits the trachea, which can prevent the intubation from leaking during oxygen supply. The suction tube is connected to the inside of the intubation tube through the right fixed port and through the wall of the intubation tube. The suction tube can timely remove the saliva and sputum in the patient's mouth. When the secretion is sucked out, the fixed port can avoid the discomfort caused by the free movement of the air tube and the suction tube to the patient. There are several occlusal grooves on the top and bottom of the tooth pad. The pad is placed in the occlusal groove to improve the comfort of the patient, and the cannula can also be fixed by biting the tooth pad.

The occlusal groove is designed as an arc structure, which is roughly the same as the order structure of the arrangement of the teeth, so as to facilitate the occlusion of the patient.

The binding rope is a snap binding rope, which can more conveniently fix the intubation tube on the patient's neck and improve the comfort of the patient.

The suction tube is provided with a cover, which can ensure the sanitation of the suction tube.

When performing tracheal intubation, first adjust the tooth pad to the approximate position and then insert the intubation tube into the patient's trachea. After insertion, check whether the intubation tube fits well with the patient's trachea. The tube expands to fit the patient's trachea completely to prevent air leakage. After the intubation is completed, adjust the tooth pad again to make the occlusal groove fit with the patient's teeth to improve the patient's comfort, and then wrap the rope around the patient's neck. The purpose of fixing the cannula again has been achieved. When there is secretion in the patient's mouth, it can be sucked out through the suction tube.

The utility model has the advantages of simple structure and low production cost, and adopts the cooperation of the adjustable tooth pad and the cannula, so that the position of the tooth pad can be adjusted according to the patient's condition, which is convenient for medical staff to adjust, and the patient can rest the teeth during occlusion through the groove. It improves the comfort of patients during intubation, and has the characteristics of convenient operation and high comfort.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and embodiments, but not as a limitation of the present utility model.

In the structures shown in Figures 1, 2, 3, 4, and 5, a tracheal intubation tube with anti-biting and flattening disclosed by the present utility model is composed of an intubation tube 1, a tooth pad 3, an inflation tube 4 and a suction tube 6. The cannula 1 is made of soft material, and a thread 10 is arranged on the cannula 1. The tooth pad 3 is designed as an oval tube, and a through port 11 corresponding to the cannula 1 is arranged in the center. Thread 10, the tooth pad 3 is movably connected with the cannula 1 through the thread 10, perforations 13 are provided on the left and right sides of the tooth pad 3, and a binding rope 2 is set on the perforation 13, and the binding rope 2 is a buckle binding rope , there are fixed ports 12 on the left and right sides of the tooth pad 3, the inflatable tube 4 and the suction tube 6 are arranged on the intubation tube 1, and the inflatable tube 4 is connected to the intubation tube 1 through the left fixed port 12, and is connected to the intubation tube 1.
