Description
まず、縦寸法:60mm×横寸法:50mm×厚さ寸法:5mmほどの大きさの図示しないスポンジに、10gの生理食塩水を含ませた。
まず、実施例1の治療パッド1の表面シート2として、孔径:0.4mmの孔6を複数開けて開孔率:0.5%の上記合成樹脂フィルムシートを用いた。そして、この治療パッド1を用いて上記試験をしたところ、上記スポンジ中に残った残液率が8%となったので、この治療パッド1にて創傷部を適度な湿潤状態に保持できることが分かった。
比較例1の治療パッド1の表面シート2として、孔径:0.4mmの孔6を複数設けて開孔率:0.6%の上記合成樹脂フィルムシートを用いた。そして、この治療パッド1を用いて上記試験をしたところ、上記スポンジ中に残った残液率が1%以下となったので、この治療パッド1にて創傷部を適度な湿潤状態に保持できないことが分かった。すなわち、この比較例1の開孔率が0.6%の表面シート2を用いた治療パッド1では、スポンジ中の生理食塩水のほぼ全量を吸収してしまい、このスポンジがほぼ乾燥した。この結果、このスポンジ中に生理食塩水の一部を残すことができなかったので、評価を×とした。
比較例2の治療パッド1の表面シート2として、孔径:0.4mmの孔6を複数開けて開孔率:0.1%の上記合成樹脂フィルムシートを用いた。そして、この治療パッド1を用いて上記試験をしたところ、上記スポンジ中に残った残液率が90%となったので、この治療パッド1にて創傷部を適度な湿潤状態に保持できないことが分かった。
