A sealing ring 17 is provided on the inner side of the guide hose 10 near the threaded ring 14. The sealing ring 17 is snap-connected to the outer side of the guide hose 11. The sealing ring 17 can seal the inner cavity of the guide hose 10. Two groups of semi-circular arc sealing rings 36 are movably provided on the outer wall of the guide hose 11. The outer sides of the semi-circular arc sealing rings 36 are connected to the inner wall of the opening of the guide hose 11. The inner side wall of the semi-circular arc sealing ring 36 can resist the outer wall of the guide hose 11 to form a sealing condition, thereby closing the opening of the elastic membrane 12 away from the vent 13.

[0026] When using the device, the diversion hose 10 of the device is pulled outward, the pipeline cavity of the guide hose 11 is evacuated outward, and the elastic membrane 12 is tightly wrapped around the outside of the guide hose 11, thereby reducing the diameter of the device and improving the passability of the device in the animal's esophagus. The device is delivered into the animal's stomach through the mouth, and air is injected into the inner cavity of the elastic membrane 12 through the guide hose 11 and the vent 13. According to the different air pressures in the elastic membrane 12, the expansion degree of the elastic membrane 12 is controlled to adapt to the esophagus of different animals. Further, the diversion hose 10 is inserted into the inner cavity of the elastic membrane 12 through the inner cavity of the externally threaded tube 16. Since the sealing ring 17 is stuck on the outside of the guide hose 11, the sealing ring 17 and the guide hose 11 remain stationary, and the diversion hose 10 can be kept in the elastic membrane 12. Under the protection, the liquid food channel is smoothly enlarged and fixed without contacting the animal's esophagus. When the diversion hose 10 moves to the limit position of the elastic membrane 12, air is sucked outwards through the guide hose 11, and negative pressure is formed in the lumen of the diversion hose 10. The two groups of semicircular arc sealing rings 36 move outwards to release the seal between the elastic membrane 12 and the guide hose 11, thereby achieving the purpose of safely establishing an artificial esophagus and facilitating further treatment of the animal. Compared with the traditional method of directly plugging into the pipeline, the device has high safety, good comfort, weak foreign body sensation, and small animal rejection reaction. The diameter of the elastic membrane 12 and the inner diameter of the external threaded tube 16 and the outer surface of the diversion hose 10 of the device can be replaced as needed.
