Abstract
Description
ポリジメチルシロキサンとポリテトラフルオロエチレンのIPNの連続したウェブを、適切なキャリア基材上で確立された方法に従って製造し、図5aに関連して示し、説明した装置と工程を使用してシリコーンゲルでコーティングした。計測された厚さが約40ミクロンの、IPN/ゲルフィルムを生成し、その後、ツールを通過させて、実質的に図2aに示すような窓を形成した。
図5a、5b、6a、6bに関連して説明した工程の卓上アナログを用いて、織布メッシュの代わりに厚さ約325ミクロンの不織布メッシュを使用したこと以外は、実施例1を繰り返した。不織布メッシュは、線形1cmにつき6個の穴の等方性の正方形パターンに孔を有するスパンレースポリエステルとした。完成形構造物の厚さは約365ミクロンであった。
非浸出性のポリコート抗菌剤(3-トリヒドロキシシリルプロピルジメチルオクタデシルアンモニウムクロライド)を3重量%含むシリコーンゲルを使用すること以外は、実施例1及び2を繰り返す。すなわち、図5aに示すリザーバ内の未硬化液状シリコーン(180a)には、非浸出性のポリコート抗菌剤(3-トリヒドロキシシリルプロピル-ジメチルオクタデシルアンモニウムクロライド)が3重量%含まれている。
銀酸化物塩を3重量%含有するシリコーンゲルを使用する以外は、実施例1、2、3を繰り返す。すなわち、図5aに示すリザーバ内の未硬化液状シリコーン(180a)には、3重量%の銀酸化物塩が含まれている。
銀酸化物塩を3重量%含有するシリコーンゲルを使用する以外は、実施例1から4を繰り返す。すなわち、図5bに示すリザーバ内の未硬化液状シリコーン(180b)には、3重量%の銀酸化物塩が含まれている。
非溶出性のポリコート抗菌剤(3-トリヒドロキシシリルプロピルジメチルオクタデシルアンモニウムクロライド)を3重量%含有するシリコーンゲルを使用する以外は、実施例1から5を繰り返す。すなわち、図5bに示すリザーバ内の未硬化液状シリコーン(180b)には、非浸出性のポリコート抗菌剤(3-トリヒドロキシシリルプロピル‐ジメチルオクタデシルアンモニウムクロライド)が3重量%含まれている。
創傷接触面(30’)が本質的に粘着性を有するように、シリコーンゲルを用いてPTFE/シリコーンIPN(10’)を調合されることと、図5aに関連して示し、説明した装置及び工程を用いてIPNをシリコーンゲルでコーティングするステップを省略することを除いて、実施例1から6を繰り返す。
ポリ乳酸、ポリラクチド、トリメチレンカーボネート、e-カプロラクトンの共重合体からなる微多孔性の再吸収性高分子膜をPTFE/シリコーンIPNフィルム(10)の代わりに使用して、微多孔質の毛細管現象によって創傷接触面(30’)に半付着性を持たせ、共重合体の温度感受性のために低温でオーブン(230)を通過させて硬化させることを除いて、実施例7を繰り返す。
