PROBLEM TO BE SOLVED: To safely and firmly hold a tube and orientated it to the jejunum by forming a plurality of bush grips dispersed in the whole length direction of the tube. SOLUTION: A jejunum supply tube 2 is provided with a manifold 4 and a stylet 6 which constitute an entry port for carrying intestinal composition. This supply tube 2 is provided with, at least, one, or preferably, two or three bush grips 22 arranged at the same intervals from the tip of a porous 20. The bush grips 22 are formed as tapered barrel projections surrounding the jejunum tube 10. The tip of each grip 22 has approximately the same diameter as the tube 10 and the diameter is gradually enlarged toward the center. This constitution can reduce the resistance, when the tube 10 passes through the esophagus, and install it without hurting the tissue. |
