PROBLEM TO BE SOLVED: To provide a drainage tube by which positioning at the time of indwelling in the body cavity and confirmation of states of side flaps can be facilitated, and which has moderate flexibility and is hard to be moved from a target region during indwelling. SOLUTION: A drainage tube 1 indwelled in a body cavity to discharge a body fluid has at least one mooring side flap 7a, 7b provided on the side wall of a tubular body, and the side flap 7a, 7b is formed by a material which has higher X-ray impermeability and higher rigidity than the material forming the tube body. Accordingly, good radioscopic images of the side flaps 7a, 7b can be obtained, indwelling work for the drainage tube 1 and the confirmation of the states of the side flaps after indwelling can be facilitated, and the locking ability of the drainage tube in the body cavity can be improved. |
