膏体・保水材層2は、水分と、当該水分が蒸発する際の気化熱を利用した冷感素材とを少なくとも含有している。
表面材層3は、繊維を不規則にからめた不織布からなり、前記膏体・保水材層2の一方の面2Aに形成される。
表面保護フィルム4は、ポリエチレン、ポリプロピレン、ポリイミドなどの生体適合性樹脂からなる。表面保護フィルム4は、前記膏体・保水材層2の他方の面2Bに形成される。この面2Bは、陰嚢への貼付面2Bとして機能する。表面保護フィルム4は、図3の一点鎖線で囲まれた部分を拡大した図に示すように、切断線BL1によって複数の部位40、41に区画されている。この切断線BL1によって、表面保護フィルム4は前記膏体・保水材層2の他方の面2Bから剥離可能に構成されている。
図4~図6は、本実施形態に係る陰嚢シートを用いた装着手順の一例を説明するための図である。
ここでは、19歳から22歳までの健康な若年男性26名を被験者とした。
ここでは、陰嚢温度と大腿温度との比較により、陰嚢冷却シートの冷却効果を検討した。
図10は、陰嚢温度と大腿温度との関係を示したグラフである。図10の横軸は陰嚢冷却シートの貼付後の経過時間[h]を示し、縦軸は温度[℃]を示す。図10中の「●」は、被験者の精巣右上の点a(図9参照)における平均温度を示し、「■」は、被験者の精巣右下の点b(図9参照)における平均温度を示す。また、図10中の「▲」は、被験者の精巣左上の点c(図9参照)における平均温度を示し、「▼」は、被験者の精巣左下の点d(図9参照)における平均温度を示す。図10中の「◆」は、被験者の大腿(図9参照)における平均温度を示す。
図11は、陰嚢温度と大腿温度との温度差を示したグラフである。図11の横軸は陰嚢冷却シートの貼付後の経過時間[h]を示し、縦軸は陰嚢温度と大腿温度との温度差を示す。図11中の「●」は、被験者の精巣右上の点a(図9参照)における平均温度と、被験者の大腿(図9参照)における平均温度との温度差[℃]を示す。図11中の「■」は、被験者の精巣右下の点b(図9参照)における平均温度と、被験者の大腿(図9参照)における平均温度との温度差[℃]を示す。図11中の「▲」は、被験者の精巣左上の点c(図9参照)における平均温度と、被験者の大腿(図9参照)における平均温度との温度差[℃]を示す。図11中の「▼」は、被験者の精巣左下の点d(図9参照)における平均温度と、被験者の大腿(図9参照)における平均温度との温度差[℃]を示す。
本発明者らは、本実験において、陰嚢冷却シートの貼付後の着け心地や、かゆみの有無についても検討した。
