[0023] Reference Figure 1-4A tracheal tube guide comprises a guide tube body 1, a connector 2 is fixedly connected to the guide tube body 1 near one side, a guide wire 3 is arranged on the inner side of the guide tube body 1, a first inflatable tube 4 and a second inflatable tube 5 are arranged on the outer surface of the guide tube body 1 near the connector 2, the first inflatable tube 4 is located at the position of the second inflatable tube 5 near the back, the bottoms of the first half cuff 7 and the second half cuff 9 are fixedly connected to the outer surface of the guide tube body 1, and an extension end 8 is fixedly connected to the end of the guide tube body 1 away from the connector 2, and the arc-shaped shape of the extension end 8 is provided. The structural design is inconsistent with the overall arc shape of the guide tube body 1, which is conducive to more convenient insertion of auxiliary equipment into the glottis and improves the convenience of equipment use. The distance between the position of the first half cuff 7 away from the connecting head 2 and the extension end 8 is about one centimeter. The first inflation tube 4 and the second inflation tube 5 are fixedly connected to the ventilation valve 6 at one end away from the extension end 8. The first inflation tube 4 and the first connecting tube 10 are integrally generated, and the second inflation tube 5 and the second connecting tube 11 are also integrally generated. The outer surface of the guide tube body 1 is fixedly connected to the first half cuff 7 at one end away from the connecting head 2.
[0024] Reference Figure 1-3 As described, the first inflation tube 4 is fixedly connected to the first connecting tube 10 near the guide tube body 1, and the first connecting tube 10 and the second connecting tube 11 are both located inside the guide tube body 1. The side of the extension end 8 away from the connecting head 2 has rounded edges, which helps to reduce the risk of trauma. The second inflation tube 5 is fixedly connected to the second connecting tube 11 near the guide tube body 1.
[0025] Reference Figure 3-4 As described, a second half cuff 9 is provided inside the first half cuff 7.
