Abstract

A medical tube 10 (drain tube 10) includes a main shaft tube 20, a flow path opening/closing mechanism 40, and a branch tube 30. The main shaft tube 20 internally has a main shaft side distal opening 21a and a main shaft lumen 21. The flow path opening/closing mechanism 40 brings the main shaft lumen 21 into a communicating state by applying pressure smaller than predetermined pressure, and brings the main shaft lumen 21 into a blocked state by applying pressure equal to or greater than the predetermined pressure. The branch tube 30 promotes a pancreatic juice pj to flow into a branch lumen 31, based on the applied pressure which is equal to or greater than the predetermined pressure.
