PROBLEM TO BE SOLVED: To provide a medical tube which is hard to adsorb a medicine and in which rupture strength is large and elasticity is rich.SOLUTION: The tube 102 in which an inner layer 121 is a material of medicine permeation resistant property, and an outer layer 123 is a material of breaking-proof property is characterized by pasting up and molding both of them. As an example of the material of medicine permeation resistant property, PBR can be mentioned, and PVC can be mentioned as an example of the material of breaking-proof property. Moreover, it is desirable that they are a material having transparency from the viewpoint of a medical tube.COPYRIGHT: (C)2012,JPO&INPIT【課題】薬剤を吸着しにくくかつ破断強度の大きく弾性に富む医療用チューブを提供すること。【解決手段】 内層121が薬剤耐浸入性素材、外層123が耐破断性素材であって、両者を接着して成型したことを特徴とするチューブ102である。薬剤耐浸入性素材の例としては、PBRを挙げることができ、耐破断性素材の例としてはPVCを挙げることができる。また、医療用チューブという観点からは透明性のある素材であることが好ましい。【選択図】図2
