Description
本出願は、2014年12月30日付出願の米国仮特許出願公開第62/098,058号、及び2015年2月6日付出願の同第62/112,714号に対する優先権を主張し、これらの開示は、本明細書においてその全体を組み込まれる。
代表的な実施形態
第1主面、第2主面、支持層周辺部、及び第1開口部を有する、湿分透過性支持層であって、
第2主面は支持層周辺部付近でその上に第1接着剤を有する、湿分透過性支持層と、
支持層の第2主面の少なくとも一部に接着した吸収性接着剤ゲルであって、接着剤ゲル周辺部を備える、吸収性接着剤ゲルと、
第1面、第2面、及び多孔性層周辺部を有する多孔性層と、を備え、
多孔性層の第1面は吸収性接着剤ゲルに接着しており、
多孔性層は流体が第2開口部へと通過するのを容易にするように構成されており、
接着剤ゲル周辺部の100%が支持層と重なりあい、
多孔性層周辺部の少なくとも50%は吸収性接着剤ゲルと重なりあっている、創傷ドレッシングである。
多孔性層は多孔性層周辺部により画定される多孔性層領域を有し、
多孔性層は少なくとも1つの開放領域を含み、
開放領域の合計は、多孔性層領域の5%以上、かつ50%以下である、先行する実施形態のいずれか1つに記載の創傷ドレッシングである。
多孔性層は多孔性層周辺部により画定される多孔性層領域を有し、
多孔性層は複数の開放領域を含み、各開放領域は多孔性層領域の5%以上、かつ50%以下である、先行する実施形態のいずれか1つに記載の創傷ドレッシングである。
鋼鉄への接着試験は、光沢のあるアニール仕上げの304AISIステンレススチールプレートを使用して行われた。プレートの寸法は51mm×127mm×1.6mmであった。試験表面は、各試験の前に、イソプロパノールを満たした使い捨ての実験用拭き取り布を使用して1回、及びn−ヘプタンを満たした使い捨て実験用拭き取り布で3回清浄化した。表面は、サンプルを試験表面上に配置する前に乾燥させた。試験試料の丈は1インチ幅であった。接着力を測定する前に、同じサンプルの接着面を鋼鉄プレートに手で押し付け、サンプルの非接着面は各方向に一度ローラを転がして、接着面をプレートに対して押し付けた。ローラは、全直径が3.75インチ(95mm)、面幅が1.75インチ(44mm)であり、75〜85デュロメータの硬さのゴムが厚さ約0.25インチ(6mm)で被覆され、4.5ポンド、すなわち2043グラムの有効ローリング重量を有した。ロール速度はおよそ50mm/秒であった。サンプルは、305mm/分の速度で180°剥離を使用して、ロールした直後に試験された。試験は、25℃及び50%の相対湿度での室内にて行われた。
