without elution of plasticizers such as phthalic acid ester, a non-vinyl chloride resin material Yes, flexibility, transparency, heat resistance, low adsorption absorption of the drug, infusion pump suitability, chemical stability, and more excellent resistance bending resistance (kink), self-adhesive is small tube resilience ( -Ko property ) and it is to provide a medical tube having excellent. The present invention includes an inner layer and at least a support layer, the support layer accounts for at least 50% of the thickness of all layers of the tube, a medical resin used in the support layer is a particular satisfying the cross-copolymer is a multi-layer tube, flexibility, transparency, heat resistance, low adsorption absorption of the drug, infusion pump suitability, chemical stability, good kink resistance, even self-adhesive less resilient tube ( -Ko of ) is characterized by excellent.フタル酸エステル等の可塑剤の溶出がなく、非塩化ビニル樹脂材料であり、柔軟性、透明性、耐熱性、薬剤の低吸着吸収性、輸液ポンプ適性、化学的安定性、さらには耐折り曲げ(キンク)性に優れ、自己粘着性が少なくチューブ復元性(耐鉗子性)に優れる医療用チューブを提供することである。本発明は、少なくとも支持層と内層を含み、支持層は少なくともチューブの全層の厚さの50%以上を占め、支持層に用いられる樹脂が特定の条件を満たすクロス共重合体である医療用多層チューブであり、柔軟性、透明性、耐熱性、薬剤の低吸着吸収性、輸液ポンプ適性、化学的安定性、耐キンク性に優れ、さらには自己粘着性が少なくチューブ復元性(耐鉗子性)に優れる特徴がある。
