The transverse parallel arrangement is different from the relation of the inner sleeve and the outer sleeve, and the inner sleeve and the outer sleeve are only required to be integrally arranged in parallel, for example, one part is arranged around the other part. It should be noted that the cross-sectional area of the decompression chamber 11 can be set according to the requirement, and correspondingly, the cross-sectional area of the nutrition line chamber 12 can also be set according to the requirement.

In some embodiments, after the extra-abdominal double-lumen feeding line is used, the tube 1 is placed such that the inner end of the tube 1 enters the abdominal cavity and the outer end is outside the abdominal cavity. When nutrient solution needs to be input, the nutrient solution is input into the abdominal cavity through the nutrient pipeline cavity 12. When pressure relief is needed, the gas in the abdominal cavity can be exhausted through the decompression cavity 11 to achieve the pressure relief effect. And the outer contour of the cross section of the tube body 1 is formed by an outward-expanding smooth curve, so that the tube body can well move in the organ tissues of the human body. And decompression chamber 11 and nutrition pipeline chamber 12 transversely set up side by side, and 11 centralizations in assurance decompression chamber that can be fine to avoid forming the undersize clearance, and then avoid blockking up. To sum up, this outer two-chamber of stomach wall nutrition pipeline can solve the problem that current nutrition pipeline result of use is not good effectively.

How the pressure reducing chamber 11 and the nutrient canal chamber 12 are formed in the tube body 1, in some embodiments, an outer tube, a pressure reducing tube and a nutrient canal may be provided, wherein the lumen of the pressure reducing tube is the pressure reducing chamber 11, and wherein the lumen of the nutrient canal is the nutrient canal chamber 12, and the pressure reducing tube and the nutrient canal are arranged side by side in the outer tube. When the pressure reducing pipe and the nutrition pipe are formed, the pressure reducing pipe and the nutrition pipe are arranged in parallel, then the pressure reducing pipe and the nutrition pipe are extruded outside the pressure reducing pipe and wrapped in the nutrition pipe, and the forming mode of the plastic pipe body can refer to the forming mode of the plastic pipe in the prior art.

In some embodiments, as shown in fig. 1, the tube 1 may be integrally formed, and the pressure reducing chamber 11 and the nutrient line chamber 12 are integrally formed, i.e. when the tube 1 is formed, i.e. when the pressure reducing chamber 11 and the nutrient line chamber 12 are formed, e.g. when the tube 1 is extruded, the pressure reducing chamber 11 and the nutrient line chamber 12 are formed separately.
