Description
使い捨てカップに入れたHYPOLヒドロゲルプレポリマー(50g;NCO含有量0.5〜1.2ミリ当量/g)に、メタノール(6g)を添加し、次いで、数秒間、十分に混合した。次いで、水(44g)をそのHYPOL混合物に添加し、次いで、激しく撹拌した。その発泡性混合物は、剥離紙の上に注ぎ、次いで、2.2mmのギャップに設定されたステンレス鋼製の手動延展機(hand spreader)を用いて延展した。その発泡体は、放置して硬化させ、次いで、その発泡体シートと剥離紙とを、オーブンに80〜100℃で30分間置いて、水分を飛ばした。結果として得られた発泡体は、0.38g/cm3の密度と、930%の破断点伸びとを有し、生理食塩水10.7g/gを吸収することができた。
CHG(グルコン酸クロルヘキシジン)を含有させる異なる方法の効果を調べるために、前記発泡性混合物の水性成分の中にCHGを2%w/vで組み入れたこと以外、実施例1の方法に従った。水性CHGによる発泡体生成物の処理は行わなかった。
発泡体の一断片を、周囲温度(20℃)で生理食塩水の貯蔵容器の中に入れ、該容器中の生理食塩水を毎日取り換えることによって、本発明の発泡体材料からのクロルヘキシジンの徐放性(sustained release)を調べた。該溶液中のCHG(グルコン酸クロルヘキシジン)濃度は、紫外線/可視分光光度計を用いて決定した。
(1)創傷接触層として使用するのに適したポリウレタン発泡体を形成する方法において、
0.5〜1.2ミリ当量のNCO基/gを含有する、イソシアネートでキャップされたプレポリマー1重量部を、C1〜C3一価アルコール0.05〜0.4重量部の存在下、水0.4〜1.0重量部と混合して発泡生成物(foamed product)を形成する工程と、
前記発泡生成物を治療薬の分散系で処理する工程と、
処理済みの前記発泡生成物を乾燥させる工程と、
を包含する、方法。
(2)実施態様1記載の方法において、
前記一価アルコールがメタノールである、方法。
(3)実施態様1または2に記載の方法において、
前記イソシアネートでキャップされたプレポリマーは、イソシアネートでキャップされたポリエーテルプレポリマーである、方法。
(4)実施態様3記載の方法において、
前記イソシアネートでキャップされたポリエーテルプレポリマーが、イソシアネートでキャップされたエチレンオキシ/プロピレンオキシ共重合体である、方法。
(5)実施態様1〜4のいずれか1項に記載の方法において、
