Description
第1の表面および弛緩動作モードにおいて第1の表面から弛緩距離だけ離れた位置に位置するさらなる表面を備える透過層と、
第1の表面とさらなる表面との間を延び、押付け動作モードにおいて、第1の表面とさらなる表面が互いに弛緩距離よりも短い圧縮距離だけ離れた位置に位置するように配置可能である複数のスペーサ要素とを備える創傷被覆材が提供される。
透過層を備える創傷被覆材を創傷部位の上方に配置することと、
創傷被覆材に対する力に応答して、透過層の第1の表面とさらなる表面との間を延びる複数のスペーサ要素を変位させることとを含み、
スペーサ要素を変位させたときに第1の表面とさらなる表面との間の距離が短くなる方法が提供される。
くつかの方形の実施形態では、透過層は、各辺の長さが9cmから19cmの間(たとえば、15×15cmの被覆材の場合は9×9cm、20×20cmの被覆材の場合は14×14cm、または25×25cmの被覆材の場合は19×19cm)であってもよい。
