摘要

The present invention relates to a tube member that does not inhibit the flow of the operation section and while ensuring the fixing strength of the connection portion of the multi-lumen tube between parts water tightness and air tightness were reliably maintained and sub lumens of multi-lumen tube fluid fixing structure is intended to provide, for that, to both the lumen is internally provided and a sub-lumen 12b inside diameter smaller than the main lumen 12a and the main lumen having a proximal end and a distal end along a longitudinal axis of the There the first tube 12 flexible that respectively open to the proximal end, and a first fixing member 13c having a base part 13g which the proximal end portion of the main lumen is connected communicated is inserted, the first tube body The first and second fixing members 13d having a contact portion to be urged to the base part via the tube body, and a connecting portion to be connected sub-lumen communicating at the proximal end side than the contact portion together are exterior to the I and a second tube member 15 and flexible with the extending portion extending from the connection portion.
