[0031] Patients receiving a gastrostomy need to have a gastrostomy tube indwelled. A conventional gastrostomy tube has a single port which is compatible with a food infusion machine of a hospital. When the patient is at home for recuperation, a nursing staff member needs to specially equip the above-mentioned food infusion machine in order to infuse food into the gastrostomy tube. However, the food infusion machine is expensive and inconvenient to carry.

[0032] In the related art, the fistula tube is designed as a whole, one end is inserted into the patient's body, the other end is exposed outside the body, and when needed, the end exposed outside the body is connected with a syringe, and the paste food is input into the patient's stomach through the fistula tube to help the patient absorb nutrients. However, the existing device is left with some food residues in the fistula tube after use, which is easy to breed bacteria.

[0033] In order to solve the problems in the related art to some extent, the embodiments of the present application provide a new type of gastrostomy tube. When it is necessary to inject and feed the patient, the ring body 25 at one end of the extension tube 12 is inserted into the inside of the shell 21. At the same time of insertion, the clamping block 26 is inserted into the inside of the shell 21 from the interval gap of the convex plate 22, so that the positioning block 28 is in contact with the inner side wall of the shell 21, and the ring body 25 is continuously inserted into the inside of the shell 21 to make the positioning block 28 retract into the inside of the clamping block 26 and squeeze the spring 27 to compress. At this time, the ring body 25 is rotated, and at the same time, the convex plate 22 can limit one side of the clamping block 26 to prevent the clamping block 26 from being separated from the inside of the shell 21. After the positioning block 28 is aligned with the positioning hole 23 in the rotating process, the spring 27 rebounds to push the positioning block 28 to move, so that the positioning block 28 extends out of the inside of the clamping block 26 and is inserted into the inside of the positioning hole 23. The rotation of the ring body 25 can be limited to some extent, and the sealing gasket 24 can play a sealing role. Then the extension tube 12 is connected with the syringe for feeding. After the feeding is completed, the ring body 25 is separated from the inside of the shell 21 by rotating the ring body 25 so that the clamping block 26 makes the positioning block 28 separate from the positioning hole 23 and aligns with the gap of the convex plate 22. Then the cover 13 is installed in the above manner to close one end of the fistula tube body 11.
