As for purpose of this invention, being soft, and the resistance kink characteristic which is superior, tensile strength offering the medical application tube which is compatible, furthermore even the occasion where this medical application tube is connected to the other tube the aforementioned quality there are times when the maintenance possible medical application tube is offered. At least, 2nd 1st it is provided outside one coil layer and the said coil layer is provided outside outside layer and the said 1st outside layer possessing outside layer, being the medical application tube which becomes, it was lower than fusion point of the material where fusion point of the material where 2nd forms outside layer 1st forms outside layer, coil external surface and the inside surface of 1st outside layer, offered the medical application tube which features that being contacted and being locked in sliding possible state.< Selective figure >Figure 1本発明の目的は、柔軟でかつ優れた耐キンク性、引張強度を両立した医療用チューブを提供すること、更にはこの医療用チューブを他のチューブに接合する際にも前記特性を維持可能な医療用チューブを提供することにある。少なくとも1つのコイル層と、該コイル層の外側に設けられる第1の外層と、該第1の外層の外側に設けられる第2の外層を有してなる医療用チューブであって、第2の外層を構成する材料の融点が第1の外層を構成する材料の融点より低く、コイル外表面と第1の外層の内表面が、摺動可能な状態で接触固定されていることを特徴とする医療用チューブを提供した。【選択図】図1
