TECHNICAL FIELD
[0001] The utility model relates to trachea technical field especially, and it is a tracheal tube. BACKGROUND
[0002] The tracheal tube needs to be used in the process of intubation, and the end of the tracheal tube needs to be deeply inserted into the patient's body. The traditional air hose is circular, does not better fit the airway, is easy to leak air, is easy to aspirate, and has stable one-time success rate. The tip is easy to cause bleeding, edema and pain of the nasopharynx and glottis.
[0003] Therefore, the utility model provides a tracheal tube to solve the above problems. UTILITY MODEL CONTENT
[0004] The utility model aims at solving the shortcomings in the prior art and provides a tracheal tube.
[0005] In order to achieve the above object, the utility model adopts the following technical scheme:
[0006] A tracheal tube, comprising a tracheal tube and a gasbag ball, the gasbag ball is sleeved on the tracheal tube, a sharp convex is arranged at the lower end port of the tracheal tube, the sharp convex is in a concave inclined shape, the tip of the sharp convex is directed to the center of the tracheal tube, a cavity is arranged in the tracheal tube, a receiving and releasing bag is filled in the cavity, a plug rod is arranged in the cavity, one end of the plug rod extends into the sharp convex, and the other end of the plug rod abuts against the receiving and releasing bag.
[0007] Preferably, the gasbag ball is arranged at 1-5 cm close to the sharp convex.
[0008] Preferably, the receiving and releasing bag is arranged in communication with the gasbag ball.
[0009] Preferably, the receiving and releasing bag is arranged at the lower end of the plug rod.
[0010] Preferably, the plug rod is arranged in an inclined manner.
[0011] Preferably, the hardness of the tip of the sharp convex gradually decreases to the end.
[0012] Compared with the prior art, the utility model has the advantages of:
[0013] 1. The sharp convex is arranged to achieve softness, bendability, and a semispherical curved tip directed to the center of the lumen, high one-time success rate of intubation, rapidness, less tissue damage, and less bleeding, edema and pain of the nasopharynx and glottis.
[0014] 2. The receiving and releasing bag and the plug rod are arranged to achieve synchronous operation of the receiving and releasing bag during inflation of the gasbag ball, control the inclination of the sharp convex by the plug rod, and better contact the internal tracheal tube, thereby improving the stability during contact.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Intubation requires the use of an endotracheal tube, the tip of which needs to be inserted deep into the patient's body. Traditional endotracheal cords are round, which don't fit the airway well, making them prone to leakage and aspiration. While their success rate is relatively stable on the first attempt, the pointed tip can easily cause bleeding, edema, and pain in the nasopharynx and glottis. Therefore, [further details are needed]. Figures 1-3 This solution designs an endotracheal intubation tube, including an intubation tube 1 and an air bag bulb 2. The intubation tube 1 includes all the components of existing devices, such as an inflation device, which will not be described in detail here.
[0021] Similar to the traditional structure, the balloon 2 is fitted onto the endotracheal tube 1. The feature is that a pointed protrusion 3 is provided at the lower end of the endotracheal tube 1. The pointed protrusion 3 is made of rubber. The balloon 2 is positioned 1-5 cm away from the pointed protrusion 3. In order to improve the success rate and prevent the tip from causing bleeding, edema and pain in the nasopharynx and glottis, the pointed protrusion 3 is concave and inclined and is set inward. The hardness of the pointed protrusion 3 gradually decreases from the end to the tip. The tip of the pointed protrusion 3 faces the center of the endotracheal tube 1.
[0022] The cavity 4 is filled with a retractable bag 5, and the cavity 4 is provided with a plug rod 6, which is obliquely arranged, one end of the plug rod 6 extends into the sharp convex 3, and the other end of the plug rod 6 abuts against the retractable bag 5, the retractable bag 5 is arranged at the lower end of the plug rod 6, and the retractable bag 5 is arranged in communication with the air bag ball 2, in the process of inflating the air bag ball 2, the retractable bag 5 is also inflated synchronously, the retractable bag 5 is inflated to change the oblique angle of the plug rod 6, so that the retractable bag 5 is operated synchronously in the process of inflating the air bag ball 2, the oblique degree of the plug rod 6 controlling the sharp convex 3 is changed, the sharp convex 3 can better contact the internal plug tube, and the stability during contact is improved.
[0023] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
