In addition, the problem of blockage of the accommodating tube in the enteric cavity is effectively prevented.

Description

technical field [0001] The invention relates to a medical gastrointestinal tube, in particular to a double-cavity visible gastrointestinal tube and a double-cavity injection device with it. Background technique [0002] Gastrointestinal tube is a medical tube suitable for transgastric nutrition supply and gastrointestinal decompression. Most of the gastrointestinal tubes in the related art are a flexible tube with openings in the area corresponding to the stomach and the area corresponding to the intestinal tract. The gastrointestinal tube with this structure is not convenient for separate drug administration in the stomach and intestinal tract. In addition, the gastrointestinal tube is a straight tube. When it is inserted into the field cavity, its lower end is easy to embed into the tissue, resulting in tube blockage, and the tube blockage has caused great trouble to subsequent treatment, and even requires re-insertion of the tube. In addition, during the intuitive proces...
