Abstract
Description
かかる包帯は典型例として、スリーサイズで作成され、全ての包帯の厚みは約0.6mmが好ましい。
実施例1
WO00/01425(一般に該特許出願の実施例2)に記載され、25g/gの吸収性および11mm/分の横方向吸上作用速度を有し、水分をからませる孔を有する織物の形態の吸収層を入手し、次いで前記のハイドロコロイド接着剤を塗布したポリウレタンフィルムに、通常の加熱積層/加圧技法により上記吸収層を接着することにより、本発明に係る創傷用包帯を作成する。積層したウェブから、包帯をプレスカットあるいはローラーカットする。
本発明包帯の種々具体例の使用特質について、商業上入手しうる術後包帯と比較する。創傷への適用に際し、実施例1の包帯は半透明であるが、滲出液を吸収すると、透明となり、創傷を観察することができる。商業上入手しうる術後包帯は、創傷への適用に際して不透明で、滲出液を吸収しても不透明のままである。
実施例1の包帯と代表的従来包帯の透明性の違いを証明するため、Kodakのグレースケールカード(grey scale card)を用いて、乾燥状態、次いで湿潤状態の包帯を通した可視性の数値示度を得る。実施例1に係る包帯を、接着剤面を上にして乾燥状態で、グレースケールに接するように置く。次いで、スケールのグレーの色相間の区分番号0〜19のライン(lines)をカウントする。大きな数字のカウントは、多くのラインを見ることができることから、透明性大を示す。実施例1の包帯が乾燥状態のとき、7ラインの区分が見られる。本発明の包帯の場合、水で湿潤させた後は、10ラインの区分が見られる。この結果は、実施例1の包帯が湿潤したとき透明性が増大することを示している。
Molnlyke のMepore包帯を用い、上記の証明実験を繰返した。この包帯もTegaderm包帯と同様、接着性フィルムとビスコース吸収材料の島から作られている。該包帯の乾燥状態で、0ラインの区分が見られる。該包帯の湿潤状態では、1ラインの区分が見られる。この結果は、Mepore包帯が滲出液の吸収時に透明とならず、かつ本発明の包帯に比し透明性が小さいことを示している。
実施例1の包帯の順応性を評価するため、伸長の力を測定する。この力は、順応性に反比例する。湿潤および乾燥時の包帯の中心部の伸長の力を測定したところ、湿潤時に、包帯をその元の長さの20%増まで伸長するのに必要な力の約75%減を示す結果が得られた。
Claims (14)
- 片面に接着剤を塗布した薄フィルム層および該薄フィルム層の接着剤面に付着した吸収層から成る術後部位の創傷用包帯であって、上記吸収層は滲出液を吸収することができることにより、該包帯を通して創傷の観察を可能ならしめることを特徴とする創傷用包帯。

- 吸収層がライオセル(Lyocell)から作られ、かつ1g当り塩化ナトリウム/塩化カルシウム溶液少なくとも10gの吸収性を有する請求項1乃至9のいずれか1つに記載の創傷用包帯。
- 薄フィルム層がポリウレタンフィルムである請求項1乃至10のいずれか1つに記載の創傷用包帯。
- 薄フィルム層が吸収層を越えて延び、該包帯を皮膚に固定する請求項1乃至11のいずれか1つに記載の創傷用包帯。
