[0002] Oral endotracheal intubation is the most commonly used method of opening the airway for resuscitation and respiratory support treatment of critically ill patients. However, the endotracheal tube needs to be fixed after intubation, otherwise it is easy to shift or fall out, affecting the patient's breathing. At present, the existing catheter fixing method is that the operator uses tape or elastic rope to fix the catheter, such as gluing the tape to the outer wall of the catheter and the human skin, which is cumbersome and easy to damage the patient's skin. Utility Model Content

[0003] In view of the problems and shortcomings in the prior art, the utility model provides a tracheal tube fixing assembly.

[0006] The first fixing member comprises a body, the inner diameter of which matches the outer diameter of the tracheal tube, and a fixing flange is provided on the inner wall thereof for matching with the fixing groove on the tracheal tube; a first fixing rope and a rope ring are provided on the outer wall thereof, and the rope ring is used for winding the dental pad rope;

[0007] The second fixing member is symmetrical in structure with the first fixing member, and a second fixing rope is arranged on the outer wall thereof, corresponding to the position of the first fixing rope, for fixing the tracheal tube on the human body.

[0008] In a specific embodiment, the first fixing member and the second fixing member are semicircular thin-walled members. Preferably, the first fixing member and the second fixing member are made of silicone. This allows the inner arm to be well matched with the outer arm of the tracheal tube, and the arc structure of the outer arm fits well with the human body without causing scratches or other damage to the human body.

[0009] A hook is provided on the matching surface of the first fixing member, and a bayonet for matching with the hook is provided on the matching surface of the second fixing member. The first fixing member and the second fixing member are matched through the bayonet, which facilitates the installation of the positioning member after the tracheal tube is intubated, and the operation is simple and convenient.

[0010] A plurality of fixing flanges are arranged at intervals up and down, so as to better position the first fixing member and the second fixing member in the tracheal tube in the axial direction and reduce the sliding of the first fixing member and the second fixing member up and down.

[0011] The height of the first fixing member and the second fixing member is 30-60 mm, so that the end of the tube that leaks out of the human body after insertion can be better fixed.

[0012] In a specific embodiment, the first fixing rope and the second fixing rope are connected by Velcro, and the length is adjustable. Specifically, the first fixing rope is provided with a hook surface of Velcro, and the second fixing rope is provided with a fur surface of Velcro. The first fixing rope and the second fixing rope are respectively fixed to the first fixing member and the second fixing member by rope buckles. Preferably, the width of the first fixing rope and the second fixing rope is 5-15 mm. This is conducive to reducing the marks of the first fixing rope and the second fixing rope on the human body.

[0013] The beneficial effects of the utility model are:

[0014] The first fixing member and the second fixing member are used to fix one side of the outer end of the tracheal tube that is normally inserted into the human body and exposed to the outside. After that, after the dental pad is put into the mouth, the rope on the dental pad is bound to the tracheal tube, and is wrapped and fixed by the rope ring. Finally, the first fixing rope and the second fixing rope are wrapped around the neck of the human body to fix the tracheal tube relatively to the human body. The structure is simple, the fixation is convenient and firm, and there is no need for the tape to contact the human skin, which can reduce the damage of the tape to the human skin.
