Abstract
Description
2つ、3つ、4つまたはそれ以上の所定圧力値と対応する時間周期とが付随的に利用されてもよい。適切に、例えば、正弦波、痛む歯、収縮−拡張などのより複雑な振幅/周波数の波形が、用意されてもよい。
ある実施形態は、カバー層140を伝達層105に少なくとも部分的に接着させてもよい。ある実施形態では、孔はポート150またはオリフィス145の直径の少なくとも1〜2mm大きい。
本発明のある実施形態では、フィルター素子130は、支持層と、支持層上に形成されるアクリル共重合体膜とを備える。適切には、本発明のある実施形態における創傷被覆材100は、微小孔疎水性膜(MHMs)を使用する。複数のポリマーがMHMsを形成するために採用されてもよい。例えば、PTFE、ポリプロピレンmPVDFおよびアクリル共重合体。これらの付随的なポリマー全ては、疎水性および疎油性の両方であり得る特定の表面性能を取得するために処理され得る。このことにより、これらは、マルチビタミン注入、脂質、界面活性剤、オイル、および有機溶剤などの低い表面張力を有する液体をはじく。
一度フィルター素子がブロックされた状態になると、吸収層の総限度容量には達していなくても、もはや負圧が傷口に伝えられない。
このようなバッフル素子は、伝達層105および/または吸収層110の領域、あるいは、吸収層110および/または伝達層105が存在しないシーリング領域内に配置または射出され得る。
さらなるオプションとして、活性炭素、シクロデキストリン、ゼオライトなどの消臭素子が吸収層に、または、フィルター層の上のさらなる層として含まれてもよい。
