Description

Technical Field

[0001] The utility model relates to a tracheal cannula fixer. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the mouth or nasal cavity and the glottis, which provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction. After endotracheal intubation, the tube usually needs to be fixed.

[0003] When fixing the endotracheal tube, medical tape is often used to fix the endotracheal tube on the patient's cheek.

[0037] like Figure 1-3 As shown, the endotracheal tube fixer includes a tube fixing cylinder 1, and also includes:

[0038] A buckle structure 5, which is arranged on the upper and lower sides of the cannula fixing tube 1;

[0039] An endotracheal cannula 2, wherein the endotracheal cannula 2 is slidably inserted into the cannula fixing tube 1;

[0040] The braces structure 3 is arranged on the buckle structure 5, and the braces structure 3 presses the buckle structure 5 to fix the endotracheal tube 2.

[0041] The cannula fixing tube 1 is made of hard plastic.

[0042] This ensures that the cannula fixing tube 1 will not be easily deformed under the action of pressure.

[0043] The top and bottom inner walls of the cannula fixing tube 1 are provided with placement grooves 4 .

[0044] The snap-fit ​​structure 5 includes a sliding rod 501, a spring 502, a connecting arc plate 503 and a fixing pad 504. The sliding rod 501 is slidably connected to the side wall of the cannula fixing tube 1. The end of the sliding rod 501 located in the placement groove 4 is fixedly connected to the connecting arc plate 503. The connecting arc plate 503 is fixedly connected to the arc-shaped fixing pads 504 on the side walls on opposite sides. One end of the spring 502 is fixedly connected to the outer wall of the cannula fixing tube 1, and the sliding rod 501 is located inside the spring 502.

[0045] The patient bites the braces 301 with his teeth, so that the two braces 301 move toward the tube fixing tube 1, and the braces 301 push the sliding rod 501 to move, the spring 502 is compressed, the sliding rod 501 drives the connecting arc plate 503 to move, and the connecting arc plate 503 drives the fixing pad 504 and the buckle block 513 to move, so that the fixing pad 504 presses against the side wall of the tracheal tube 2.

[0046] The fixing pad 504 is made of silicone.

[0047] The friction coefficient of silica gel is relatively large, so that the friction between the fixing pad 504 and the endotracheal tube 2 is relatively large, thereby limiting the movement of the endotracheal tube 2.

[0048] The size of the connecting arc plate 503 matches the placement groove 4, and the curvature of the side wall of the fixing pad 504 close to the endotracheal tube 2 is consistent with the curvature of the outer side wall of the endotracheal tube 2.

[0049] The fixing pad 504 can be well fitted on the side wall of the endotracheal tube 2, thereby increasing the fitting area with the endotracheal tube 2.

[0050] The snap-fit ​​structure 5 includes a second placement groove 511 and a snap-fit ​​block 513. The second placement groove 511 is opened on the side wall of the fixing pad 504. The snap-fit ​​block 513 is fixedly connected to the side wall of the connecting arc plate 503. The snap-fit ​​block 513 is located in the second placement groove 511 and has a conical structure.

[0051] The buckle block 513 abuts against the side wall of the endotracheal tube 2 to form a depression, thereby further limiting the movement of the endotracheal tube 2 .

[0052] The tip of the buckle block 513 is configured to be in an arc shape.

[0053] Prevent the buckle block 513 from puncturing the side wall of the endotracheal tube 2.

[0054] The height of the buckle block 513 is greater than the thickness of the fixing pad 504 .

[0055] When the fixing pad 504 fits against the side wall of the endotracheal tube 2 , the buckle block 513 can press against the side wall of the endotracheal tube 2 to form a depression.

[0056] The braces structure 3 includes a braces 301 and a supporting arc plate 302 , wherein the braces 301 is fixedly connected to the other end of the sliding rod 501 and the spring 502 , and the braces 301 are fixedly connected to each other by a connecting arc plate 503 , and the connecting arc plate 503 is located at the end of the braces 301 .

[0057] The patient's mouth is closed so that the patient's upper and lower teeth are respectively fitted into the upper and lower braces 301 , and the movement of the braces 301 is restricted by the patient's teeth, and the movement of the cannula fixing tube 1 is then restricted by the braces 301 .

[0058] When the utility model is in use, after the tracheal cannula 2 is inserted, the cannula fixing cylinder 2 can be slid for fixing, and the cannula fixing cylinder 2 drives the upper and lower tooth guards 301 to move along the tracheal cannula 2 through the sliding rod 501, so that the tooth guards 301 are located between the upper and lower teeth of the patient, and then the patient's mouth is closed, so that the upper and lower teeth of the patient are respectively sleeved into the upper and lower tooth guards 301, and the movement of the tooth guards 301 is restricted by the patient's teeth, and then the movement of the cannula fixing cylinder 1 is restricted by the tooth guards 301, so that the tracheal cannula 2 fixer can be better fixed with the help of the patient's teeth, and the tracheal cannula 2 fixer can be prevented from falling off;

[0059] The patient bites the dental braces 301, so that the two dental braces 301 move toward the cannula fixing tube 1, and the dental braces 301 push the sliding rod 501 to move, the spring 502 is compressed, the sliding rod 501 drives the connecting arc plate 503 to move, and the connecting arc plate 503 drives the fixing pad 504 and the buckle block 513 to move, so that the fixing pad 504 is against the side wall of the tracheal cannula 2. Since the curvature of the side wall of the fixing pad 504 close to the tracheal cannula 2 is consistent with the curvature of the outer side wall of the tracheal cannula 2, The fixing pad 504 can fit well on the side wall of the endotracheal tube 2. The fixing pad 504 is made of silicone. The friction coefficient of silicone is relatively large. By making the friction between the fixing pad 504 and the endotracheal tube 2 relatively large, the movement of the endotracheal tube 2 can be limited. The buckle block 513 presses against the side wall of the endotracheal tube 2 to form a depression, thereby further limiting the movement of the endotracheal tube 2, making it easier to fix the endotracheal tube 2 and avoiding the use of medical tape to fix it, which may cause damage to the patient's facial skin.
