Abstract
Description
大きすぎて自然には閉じられない、もしくはそうでなければ、創傷の部位への陰圧の適用では治癒しない、開放創または慢性創傷の治療は、当該技術分野ではよく知られている。現在当該技術分野で知られている陰圧創傷療法(NPWT)システムは、創傷の上に流体に対して不透過性または半透過性の被覆を置くことと、創傷を囲む患者の組織に対して被覆を封止する、様々な手段を使用することと、陰圧を被覆の真下に作り出し維持するような手法で、陰圧の源(真空ポンプなど)を被覆に接続することとを伴う。このような陰圧は、創傷部位における肉芽組織の形成を促進し、かつ人体の通常の炎症プロセスを補助しながら、同時に有害なサイトカインおよび/またはバクテリアを含む可能性がある過剰な流体を除去することにより、創傷の治癒を促進すると考えられている。しかしながら、治療の便益を完全に実現するには、NPWTのさらなる改良が必要とされる。
