PROBLEM TO BE SOLVED: To provide a drain tube that can achieve both suppression of kinks of an outflow tube part and easiness in detaining a suction tube part at a target position in a body.SOLUTION: In a drain tube 1, a suction tube part 2, a connection tube part 3, and an outflow tube part 4 are integrally formed from a dital end in this order. A flow channel passing from the distal end to a rear end is formed inside these. A partition part extending from the distal end to a rear end of the connection tube part 3 is provided inside the suction tube part 2 and the connection tube part 3. A plurality of flow channels partitioned by the partition part and extending in an axial direction are formed inside the suction tube part 2 and the connection tube part 3. The plurality of flow channels merge into one at the boundary portion between the connection tube part 3 and the outflow tube part 4. One or more slits 18 extending from the distal end along the flow channels partitioned by the partition part are formed on an outer wall of the suction tube part 2. The hardness of the outflow tube part 4 is higher than the hardness of the suction tube part 2.SELECTED DRAWING: Figure 1【課題】流出管部のキンク抑制と吸引管部の体内の目的位置への留置容易性とを両立できるドレーンチューブを得ることを目的とする。【解決手段】先端から順に吸引管部２、連結管部３及び流出管部４が一体に形成され、それらの内部に先端から後端まで通じる流路が形成され、吸引管部２及び連結管部３内に、先端から連結管部３の後端まで延びる仕切り部が設けられ、吸引管部２及び連結管部３の内部には、前記仕切り部によって仕切られた軸方向に延びる複数の流路が形成され、それら複数の流路は連結管部３と流出管部４の境界部分で１つに合流し、吸引管部２の外壁には、先端から前記仕切り部で仕切られた流路に沿って延びるスリット１８が１つ以上形成され、流出管部４の硬度が吸引管部２の硬度よりも高くなっている、ドレーンチューブ１。【選択図】図１
