The gastric tube main body (100) is placed in the digestive tract; when no food/drink is being delivered through the feeding tube (110), the feeding tube (110) is in a collapsed state at a narrow part in the digestive tract so as to alleviate the pain of a patient during insertion of the gastric tube and during the long-term indwelling of the gastric tube in the digestive tract; and when food/drink is being delivered through the feeding tube (110), the feeding tube (110) is filled and expands so as to facilitate the passage of a liquid diet, and is not easily blocked. The double-channel gastric tube can alleviate the pain during insertion of the gastric tube and during the long-term indwelling of the gastric tube in the digestive tract, and facilitates the passage of a liquid diet and is not easily blocked.
