PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a medical tube to which a biological material or medical liquid is less likely to adhere.SOLUTION: A method for manufacturing a medical tube is a method for manufacturing a medical tube having a micro concavo-convex structure on the inner surface, and includes an extrusion process for molding a tube material by extrusion molding, an insertion process for inserting a core rod member having a micro concavo-convex pattern on the outer surface from a tip opening of the tube material extruded in a predetermined extrusion direction in the extrusion process, and a transfer process for transferring the micro concavo-convex pattern to the inner surface of the tube material by moving the tube material and the core rod member in the predetermined extrusion direction in a state that the inner surface of the tube material is caused to come in contact with the micro concavo-convex pattern on the outer surface of the core rod member.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】生物学的物質又は医療用液体が付着しにくい医療用チューブの製造方法及び製造装置を提供する。【解決手段】本発明に係る医療用チューブの製造方法は、内面に微細凹凸構造を有する医療用チューブの製造方法であって、押出成形によりチューブ材を成形する押出工程と、前記押出工程により所定の押出方向に押し出された前記チューブ材の先端開口から、外面に微細凹凸パターンを有する芯棒部材を挿入する挿入工程と、前記チューブ材の内面と前記芯棒部材の外面における前記微細凹凸パターンとを接触させた状態で、前記チューブ材及び前記芯棒部材を前記所定の押出方向に移動させることにより、前記微細凹凸パターンを前記チューブ材の内面に転写する転写工程と、を含む。【選択図】図8
