Abstract
Description
・一方では、静脈の径を小さくして、結果として血流を促進し、弁機能を回復させることによる血管に対する効果;
・他方では、よりよい酸素化及び浮腫の再吸収を促すことによる組織に対する効果。
・一方では、筋肉が弛緩している時には、着用感がよく、特に夜間も耐えられるように比較的低い圧力(「静止圧」と呼ばれる);
・他方では、筋肉が緊張している時又は運動中、特に歩行中には比較的高い圧力(「動作圧」と呼ばれる)。
上記試験に基づき、これを基準として、伸び率が100%以下の圧迫包帯は「ショートストレッチ」包帯とみなされる。
上述の試験に基づき、これを基準として、伸び率が100%を超える包帯は「ロングストレッチ」包帯とみなされる。
・上記弾性材料と上記不織布は互いに貼り合わされており、
・上記不織布は坪量が70g/m2〜300g/m2であり、
・上記捲縮繊維は、上記不織布の厚み方向に均一に捲縮しており、平均曲率半径が10〜200μmであり、上記不織布の表面の捲縮繊維数は10本/cm2より多い、
圧迫包帯である。
・非対称芳香族ジカルボン酸、特にイソフタル酸、フタル酸又は5−スルホイソフタル酸ナトリウム塩、
・脂肪族ジカルボン酸、特に脂肪族C1−12ジカルボン酸(アジピン酸など)、
・アルカンジオール、特に1,3−プロパンジオール、1,4−ブタンジオール、1,6−ヘキサンジオール又はネオペンチルグリコール、又は、

・不織布の表面の捲縮繊維数**27/cm2
*上述の方法に従って測定
**上述の方法に従って測定
ニードリング又は接着剤のポイント塗布といった様々な貼り合わせ法を用いて包帯を製造した。
リニアメートル当たり2500本のニードルを有するボードを備えたFehrer社製ニードリング装置においてニードリングによる積層試験を行った。
ニードリング1ラインの実施条件は以下の通りである。
・ニードリングラインの生産速度:1m/分
・針深度:実施例1では10mm、実施例2では13mm
・針密度:50パンチ/cm2
ニードリング2ラインの実施条件は以下の通りである。
・ライン速度=1m/分
・針深度:13mm
・針密度:50パンチ/cm2
接着剤を沈着させるのに必要な塗布温度が不織布と適合する場合に接着剤による貼り合わせを行った。包帯が追加層を含んでいる場合には、その層の表面は、接着剤が均一に分布するように充分に平坦でなければならない。
・装置の試験条件:
操作速度=2m/分
ロールスロット=0.3mm
ロールシリンダー圧=3bar
アンビルロール圧=2.5bar
加熱温度=188℃
接着剤温度=180℃
実施例1〜6の圧迫包帯の性能を、かかる動作圧及び静止圧と圧力差を経時的に測定することによって評価した。
表2の結果を分析することによって、本発明に係る圧迫包帯の性能を実証する。
