Abstract
【解決手段】
本発明は、使用者の面に対向して装着されかつ界面を形成する密封材(18)を備えた密封材及びマスクである。密封材は、ゲル物質で形成された第1の部分と、第1の部分に取り付けられた第2の部分(16)とを備える。第2の部分は、選択的に形成可能な物質を含み、第1のパターンから第2のパターンに成形され、成形された状態に応じて第2のパターンを保持する。密封材の形成可能な部分を順応状態で配置することによって、密封材を有する密封マスク(12)は被験者に合わせて調整され、固定状態で形成可能な部分を配置して、密封材の下に位置する被験者の部位に密着する形を通常保持する。

Description
コクランによる研究で、ゲル及び泡を含むクッション材料の数種が検討された(下記非特許文献1)。この研究では、車椅子のクッションとして使用するクッション材料の皮膚温度に対する材料の効果、皮膚−クッション界面での熱流束及び相対湿度等の相対的な長所及び短所を比較した。局所的な血流圧力レベルを超えて圧力を供給すると、前記ファクターの各々は皮膚−クッション界面での皮膚組織を破壊する一因となることが判明した。
