PURPOSE:To provide a retained tube in vivo having an internal cavity unlikely to clog and highly resistant to bending with an inexpensive constitution. CONSTITUTION:In a retained tube 1 in vivo having a fluorine resin inside tube 3 formed on the inside of an outside tube 2, a reinforcing blade 10 is provided between the outside tube 2 and the inside tube 3. The internal cavity of the retained tube 1 is difficult to clog, and the mechanical strength such as bending property of the retained tube 1 is enhanced. |
