It is a type of unilateral lung ventilation tool that can be placed in the left or right main bronchus to implement unilateral lung isolation and unilateral lung ventilation. The two lumens in one tube can replace the human respiratory tract when unilateral lung ventilation is independent, synchronous or asynchronous. In order to improve the antibacterial effect of the double-lumen endotracheal tube, a special antibacterial layer, such as silver ion coating and chlorhexidine coating, is sometimes applied to the tube.

[0003] However, existing double-lumen endotracheal intubations have the following problems in use: The bronchi are usually directly connected to the main trachea and distributed on both sides of the main trachea. However, in actual operation, because the bronchial tubes are generally made of rigid materials, it is often necessary to pre-place the devices to be connected to the bronchial tubes, such as drainage bags or suction devices, in a position convenient for connection to avoid bronchial kinking and obstruction. Furthermore, there is a lack of means to flexibly adjust the bronchial tubes. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an antibacterial coated double-lumen endotracheal cannula, comprising a double-lumen endotracheal cannula body and an antibacterial coating 1 coated on the double-lumen endotracheal cannula body. The double-lumen endotracheal cannula body includes a main endotracheal tube 2, bronchial bodies 3, a tracheal cuff 4, and a movable connecting mechanism 5. The bronchial bodies 3 are divided into two groups, and connectors 6 are installed at the outer ends of both groups of bronchial bodies 3 and the main endotracheal tube 2. The tracheal cuff 4 is installed on the main endotracheal tube 2. The main endotracheal tube 2 has a two-section structure, and the connection point is connected to the movable connecting mechanism 5. Next, the movable connecting mechanism 5 includes a hollow guide balloon 7 and a locking assembly 8 used in conjunction with the hollow guide balloon 7. The two ends of the hollow guide balloon 7 are respectively movably connected to the two sections of the main air pipe 2. The hollow guide balloon 7 has an inner cavity 9 and several sets of limiting slots 10 are evenly opened at the upper end. The several sets of limiting slots 10 are distributed in a ring. The locking assembly 8 is installed on the main air pipe 2 and includes two sets of protrusions 11 symmetrically installed on the main air pipe 2 and a rod 12 fixed on the protrusions 11. The rod 12 is inserted into the limiting slot 10.

[0019] Further improvements, such as Figure 1 As shown, the antibacterial coating 1 is a silver ion coating that is evenly applied to the surface of the double-lumen endotracheal tube body, which can achieve the purpose of antibacterial treatment.
