Double-cavity nasal and gastrointestinal tube

The utility model relates to a double-cavity nasal and gastrointestinal tube which comprises a tube body and an interlayer. The interlayer extends along the length direction of the tube body to divide the tube body into two cavities. One cavity is used as a wire guide cavity, and the other cavity is used as an infusion tube cavity. One end of the wire guide cavity is open, and the other end of the wire guide cavity is a blind end. A section of support body is arranged in the blind end. A plurality of side holes are arranged at the blind end in the infusion cavity. The length of the support body is matched with the distribution length of the side holes. After the nasal and gastrointestinal tube enters a human body, in the using process, the support body is arranged at the positions of the holes, so that the nasal and gastrointestinal tube cannot be bent, thereby effectively ensuring the smoothness of a catheter.
