[0030] As shown in Figures 1-3 An embodiment of a tracheal tube plugging device is shown in FIG. 1. The device includes a tracheal tube 1 and a plug 2. One end of the tracheal tube 1 is used to be inserted into a patient's body, and the other end is used to be connected to a breathing machine. The plug 2 is movably arranged at the end of the tracheal tube 1 for connecting to the breathing machine. The plug 2 is a hollow structure. The upper end of the plug 2 is a closed end 20, and the lower end of the plug 2 is an open end 21. The side wall of the plug 2 is provided with one or more air vents 22 in communication with the open end 21. Air enters the hollow structure of the plug 2 through the air vents 22, and then enters the tracheal tube 1 through the open end 21. By controlling the depth of the plug 2 inserted into the end of the tracheal tube 1, the opening size of the air vents 22 in contact with the external environment is controlled, thereby controlling the air flow rate entering the tracheal tube 1 from the plug 2.

[0031] In use, the tracheal cannula 1 connected with the breathing machine is pulled out, and the plug 2 is slowly inserted into the tracheal cannula 1, the air inlet 22 is gradually blocked by the wall of the tracheal cannula 1, so that the amount of air entering is reduced, until the air inlet 22 is completely blocked to achieve plugging, so that the patient gradually adapts. The above scheme effectively solves the technical problems that the tracheal plugging operation in the prior art can only be realized full plugging or full opening, cannot realize selective ventilation, and cannot realize instant oxygen cannula when the patient's breathing appears serious difficulty.

[0032] As shown in Figure 2 and Figure 3 in some embodiments of the utility model, the air inlet 22 is a through groove extending up and down along the side wall of the plug 2. When the plug 2 is gradually inserted into the tracheal cannula 1, the through groove is also gradually blocked by the wall of the tracheal cannula 1, so that the amount of air entering is reduced, the two ends of the through groove are rounded, which is beneficial to the smooth transition of the amount of air entering, so as not to appear cliff type drop, which helps the patient to better adapt. It is particularly pointed out that the through groove is only the best embodiment of the application, wherein other forms of the air inlet 22 include but are not limited to a plurality of small holes distributed up and down along the side wall of the plug 2, or a circular hole, an elliptical hole and the like, and structures similar to the principle of the application should be included in the protection scope of the application.

[0033] As shown in Figure 2 and Figure 3 in some embodiments of the utility model, the air inlet 22 is symmetrically provided with two groups relative to the plug 2. The two groups of air inlets 22 ensure that the plug 2 has good structural strength while ensuring a larger air inlet, and in use, the finger position is away from the two sides of the plug 2 avoiding the two air holes, so as to avoid blocking the air inlet 22.

[0034] As shown in Figure 2 and Figure 3 in some embodiments of the utility model, the closed end 20 is provided with a boss outwardly. The boss is beneficial to the insertion and pulling operation of the plug 2 by medical staff, and the boss can also avoid that the plug 2 is inserted too deep and the closed end 20 is immersed into the tracheal cannula 1, which leads to difficulty in pulling out. It is particularly pointed out that the boss is not limited to the structure form provided in the drawings of the application, but can also be provided in the form of a pull ring, a cover and the like, and structures similar to the principle of the application should be included in the protection scope of the application.

[0035] As shown in Figure 2 and Figure 3As shown, in some embodiments of the present invention, the sidewalls of the plug 2 are sloped, and the open end 21 is chamfered. The sloped sidewalls of the plug 2 reduce friction between the sidewalls and the wall of the endotracheal tube 1 during insertion, facilitating smoother insertion. The chamfered open end 21 facilitates alignment of the plug 2 with the endotracheal tube 1, allowing for faster insertion.

[0036] like Figure 4 As shown, in some embodiments of the present invention, a filter 3 is disposed within the hollow structure of the plug 2. After the ventilator-connected tube is removed from the endotracheal tube 1, the tube 1 is directly exposed to the outside air. Impurities in the air enter the patient's body without being filtered, potentially adversely affecting the patient's health. By disposing the filter 3 within the hollow structure of the plug 2, medical personnel can filter out impurities from the air inhaled into the endotracheal tube 1 through the filter 3 while caring for the patient, thereby reducing the amount of impurities in the air inhaled by the patient and preventing adverse effects on the patient's health.

[0037] like Figure 4 As shown, in some embodiments of the present invention, the filter 3 includes a filter screen 30 and a filter material 31. The filter screen 30 is arranged to wrap around the filter material 31, and the filter screen 30 and the filter material 31 are filled in the hollow structure of the plug 2. The filter screen 30 can prevent large particles of debris from entering, while ensuring that the filter material 31 maintains a certain shape. The filter material 31 can be made of a porous structure such as activated carbon to further filter impurities in the air.

[0038] like Figure 5 As shown, in some embodiments of the present invention, a connecting strap 4 is provided between the plug 2 and the endotracheal tube 1. The connecting strap 4 connects the plug 2 and the endotracheal tube 1 into a single unit, making them easy to handle and prevent them from falling or being lost due to improper handling. Furthermore, the connecting strap 4 is made of a flexible material and does not affect the normal use of the plug 2.

[0039] like Figure 5 As shown, in some embodiments of the present invention, a detachable protective cover 5 is provided on the outside of the plug 2. When the plug 2 is not in use, the plug 2 is wrapped by the protective cover 5 for protection, thereby preventing the plug 2 from being contaminated by the external environment.

[0040] So far, the various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.
