温熱的観点からみた乳がん術後女性のための補整具素材の水分特性

摘要

乳がん手術によって片方の乳房を喪失(全摘)した女性のために，温熱的に快適な補整用パッドの水分特性を明らかにした.乳がん術後女性6人を被験者として用いた.実験用のパッド素材として，シリコンゲル，ウレタンフォーム，綿わたおよびポリエステルわたを使用した.着用実験の結果，吸湿性および透湿性がほぼゼロであるシリコンパッド装着時において，パッド内湿度が最も高く，パッド内温度が最も低かった.また，その生理応答として，口腔温および平均皮膚温が歩行後に急激に上昇することがわかった.吸湿性および透湿性が高かった綿パッド装着時には，実験中最も湿度が低かった.パッド素材の水分特性として，透湿性が高いことを前提に，高い水分率をもつ素材からなるパッドおよびパッドカバーが適切であることがわかった.%The water characteristics of pads worn by women for breast shape adjustment after removal of one breast as a result of breast cancer surgery were clarified from the viewpoint of thermal comfort. Six females who had undergone breast cancer surgery participated as subjects. The pad materials studied in the experiment included silicone gel, urethane foam, cotton, and polyester. The results showed that the highest humidity and lowest temperature on the inside of the pad were observed for the silicone pad, for which the hygroscopicity and moisture permeability are approximately zero. In addition, it was found that the mean skin temperature and oral temperature rose rapidly after walking, as physiological responses. The humidity on the inside of the pad was the lowest for cotton padding, for which the hygroscopicity and moisture permeability are high. Assuming that the material has high moisture permeability, it is important for the pad and cover materials to have a high moisture regain in order to reduce thermal discomfort for the wearer.
