Abstract
【解決手段】 樹脂製医療用被接合部材に外側から挿通して加熱によるブロッキングにより密着接合させる医療用押出成形二層チューブであって、内層には、ポリエチレン、ポリプロピレン、スチレン系エラストマー、オレフィン系エラストマー、もしくはこれらの混合物ないしこれらを主成分とする素材であって、前記加熱温度以下の融点をもつ素材を用い、外層には、ポリプロピレン、スチレン系エラストマー、オレフィン系エラストマー、もしくはこれらの混合物ないしこれらを主成分とする素材であって、前記加熱温度を越える融点をもつ素材を用い、外層の肉厚がチューブ全体の肉厚に対して2%〜5%であることを特徴とする医療用押出成形二層チューブである。
【選択図】なし
Description
ブロッキングによる密着接合は、被接合部材等との所望の接合箇所では好適であるものの、チューブ同士のブロッキングや、チューブと包装用樹脂フィルムとのブロッキングも生じ、患者が包装用樹脂フィルムを剥がしにくく、製品の取扱性に劣るという問題点があった。
本発明の医療用押出成形二層チューブは、内層と外層とを有する二層構造であり、内層には柔軟性素材を使用し、外層には、融点の高い素材を採用する。
Claims (2)
- 樹脂製医療用被接合部材に外側から挿通して加熱によるブロッキングにより密着接合させる医療用押出成形二層チューブであって、
