Description
図1Aおよび図1Bは、静的陰圧装置100の一実施形態を例示している。装置100は、密封層110(本明細書では時には密封構造とも呼ぶ)と、組織外傷の外科部位、例えば、外科切開部の長さに沿って圧力を分配するように構成された収集チャンバ120(本明細書では時には収集構造とも呼ぶ)とを備えている。この装置は、本明細書では皮膚である組織に関連して説明されているが、皮膚以外の生物学的組織にも使用できることを理解されたい。一部の実施形態では、陰圧治療装置は、接触層130を備えることができる。接触層130は、収集チャンバ120と皮膚外傷部との間を流体連通させる。接触層130は、例えば、発泡体、メッシュ、ガーゼ、スポンジ、粒状物質、積層メッシュマトリックス、またはあらゆる他の適切な多孔質生体適合性材料を含み得る。接触層130は、外科的に閉鎖された皮膚外傷部の表面に接触するように配置することができる。場合によっては、接触増130は、外科部位を通る空気/流体空間の連続性を維持するように構成することができ、これにより、外科部位および密封層110によって形成された閉鎖された空間における流体の隔離または空気小嚢の発生を低減することができる。一部の実施形態では、接触層は、皮膚外傷部の表面の境界内とすることができ、皮膚外傷部を取り囲んでいる近接組織部分に接触しない、重ならない、または覆わないようにすることができる。他の実施形態では、接触層は、皮膚外傷部自体に加えて、皮膚外傷部を取り囲んでいる近接組織に接触して配置することができる。図1Aに示されているように、接触層130と、密封層110と、収集チャンバ120とは、互いに結合する、または一体にすることができる。一部の例では、予め結合または一体にされたデザインにより、1つの工程で、装置100を皮膚外傷部の表面に接触させて配置することができる。一部の実施形態では、接触層は、皮膚外傷部の表面に接触させて配置することができる。配置されたら、接触層を、収集チャンバと一体になった密封層で覆って密封されたエンクロージャまたは空間を形成する。一部の実施形態では、密封層は、限定されるものではないが、テープ、糊、または適切な生体適合性接着製品を含め、あらゆる適切な材料または当技術分野で周知の機構によって外傷部を取り囲んでいる皮膚の部分に取り付けることができる。
