Description
本出願は、2014年6月13日に提出された米国仮出願第62/011,654号の利益を主張するものであり、米国出願は全てが本明細書に参照として含まれる。
本発明の組成物は、傷からの滲出液を調節するような医療適用に使用される流体処理接着剤組成物として幅広く適用されるだろう。しかし、本発明は、他の適用を含み、医療分野に限定されない。上記組成物は、一つ以上の接着剤成分、及び一つ以上のゲル化剤と一つ以上の非ゲル化崩壊剤との組み合わせ物を含む。非ゲル化崩壊剤とゲル化剤との組み合わせ物を本明細書に説明される比率及び方式で使用することは、最終接着剤組成物に多い利点を提供するということを見出した。多数の実施の形態で、接着剤組成物は通気性が高い。本明細書に使われる“通気性が高い”という語句は、少なくとも2000g/m2/24時間の流体処理能(FHC)又は800g/m2/24時間のMVTRを示す接着剤を言う。
多数の接着剤を使用することができる。多数の実施の形態で、溶剤系接着剤が用いられる。このような接着剤の非限定的な例は、アクリル接着剤、ゴム接着剤、シリコン接着剤、ポリウレタン接着剤、ハイブリッド接着剤、及びそれらの変形及び組み合わせ物を含む。所定の実施の形態で、接着剤は、感圧溶剤系接着剤である。特に、接着剤は、感圧溶剤系アクリル接着剤である。
一つ以上のゴム系接着剤が用いられてもよい。好ましいゴム系接着剤の非限定的な例は、一つ以上のスチレン−イソプレン−スチレンポリマー、スチレン−エチレン/プロピレン−スチレンポリマーを含むスチレン−オレフィン−スチレンポリマー、ポリイソブチレン、スチレン−ブタジエン−スチレンポリマー、ポリイソプレン、ポリブタジエン、天然ゴム、シリコンゴム、アクリロニトリルゴム、ニトリルゴム、ポリウレタンゴム、ポリイソブチレンゴム、ブチルゴム、ブロモブチルゴムを含むハロブチルゴム、ブタジエン−アクリロニトリルゴム、ポリクロロプレン及びスチレン−ブタジエンゴムを含む。エラストマの組み合わせ物又は混合物が用いられてもよい。
通常、接着剤組成物に含めるために選択するゲル化剤は、水分との接触時にゲルを形成する任意の物質を含む。接着剤に使用される一般的なゲル化剤は、カルボキシメチルセルロース、ヒドロキシエチルセルロース、メチルセルロース、クロスカルメロースナトリウム、澱粉グリコレートなどのような材料を含む。本発明の特定の実施の形態で、ゲル化剤は、(i)カルボキシメチルセルロース、及び(ii)クロスカルメロースナトリウムの一つ以上から選択され得る。
本発明の組成物は、一つ以上の非ゲル化崩壊剤も含む。崩壊剤は、錠剤(tablet)に添加されるときに薬物放出を容易にするために水性流体と接触する時に錠剤の分解を誘導するために用いられる賦形剤である。本明細書に使われる用語“非ゲル化崩壊剤”は、流体と接触する間及び接触する時にゲルを形成しない崩壊剤を意味する。具体的に、非ゲル化崩壊剤は、接着剤組成物を通した水の吸収及び通過を促進し、組成物の全体的な多孔性を増加させ、及び/又は組成物の毛細管作用又はウィッキング(wicking)を増加させる役割を担うが、ゲルを形成しない。非ゲル化崩壊剤は、(i)微結晶質セルロース、(ii)ジャガイモ澱粉、及び(iii)変性澱粉の一つ以上から選択され得る。また、(i)〜(iii)の組み合わせ物が使用されてもよい。
一つ以上の付加添加剤を接着剤組成物に含めることができる。特に、付加添加剤は医薬化合物を含む。このような医薬化合物は、抗菌剤、抗生剤、抗真菌剤、抗ウイルス剤、抗血栓剤、麻酔剤、抗炎症剤、鎮痛剤、抗ガン剤、血管拡張物質、傷治療剤、血管形成剤、血管新生抑制剤、免疫増進剤、成長因子、及びその他生物学的製剤を含むが、それらに限定されない。適切な抗菌剤は、ビグアニド化合物;トリクロサン;ペニシリン;テトラサイクリン;ゲンタマイシン及びトブラマイシンTMなどのアミノグリコシド;ポリミキシン;リファンピシン;バシトラシン;エリスロマイシン;バンコマイシン;ネオマイシン;クロラムフェニコール;ミコナゾール;オキソリン酸、ノルフロキサシン、ナリジクス酸、ペフロキサシン、エノキサシン、及びシプロフロキサシンなどのキノロン;スルフォンアミド;ノノキシノール9;フシジン酸;セファロスポリン;及びこのような化合物及び類似化合物の組み合わせ物を含むが、それらに限定されない。追加抗菌性化合物は、向上した坑菌活性を提供する。
また、本発明は、上記言及された組成物を使用する多数の接着剤物品及び特に接着性医療物品を含む。上記物品は、一つ以上の基材又は他の層又は成分、上記言及された接着剤組成物の一つ以上の層又は領域、及び一般的に接着剤組成物の層又は領域を覆うライナー又はライナー組立体を含む。上記物品は、一つ以上のカバー又はバッキング層又は成分を任意に含むことができる。
基材材料は、エラストマ性ポリウレタン、ポリエステル、又はポリエーテルアミドフィルムを含むが、それらに限定されない。好ましい特性は、高い水蒸気及び酸素透過性、弾性、順応性を含み、所定の実施の形態において透明性を含む。ポリプロピレン(PP)又はポリエチレン(PE)のような 使い捨ての2次バッキングフィルムを使用して、取扱上の容易性をさらに提供することができる。代案として、通気性のペーパー又はテキスタイルバッキングを適切に使用することができる。このようなペーパー又はテキスタイルバッキングの追加の例は、“A Review on Designing the Waterproof Breathable Fabrics,” A.Mukhopadhyay;V.K.Midha,Journal of Industrial Textiles,Part 1−37,225(2008)& Part II−38,17(2008)及び米国特許第6,495,229号及び関連特許に提供される。
接着剤物品は、上記言及された接着剤組成物の一つ以上の層又は領域を含む。接着剤層は、公知の適用技術によって基材上に塗布されたり、他の方法で蒸着される。一般に、接着剤は、厚さが0.01mm〜約5mmであるか、これより厚く、特定の実施の形態において厚さが0.05〜2mmの範囲内である層状に塗布される。接着剤の表面被覆率は5%(パターンコートされる場合)〜100%(完全にコートされた基材)であってもよい。
ライナーに適切な材料は、クラフト紙、ポリエステル、ポリプロピレン(PP)、ポリエチレン(PE)又は他の複合構成物で製造されるものを含む。離型コーティングは、有利な性能を提供するシリコン、フルオロ化合物などのような低エネルギー材料でまずコートされる。代表的なシリコン材料の例は、Chapter18,Handbook of Pressure Sensitive Adhesives,Van Nostrand Reinbhold,1982、ページ384に提供されている。適切なフルオロ化合物の例は、米国特許第4,472,480号に説明されている。
また、本発明は、上記言及された組成物を用いた様々な方法を提供する。上記方法は、傷治癒を促進させることに関し、これは、傷からの滲出液のような流体の吸収、及び流体処理適用を含むことができる。通常、上記方法は、上記言及された接着剤組成物の少なくとも一つの層又は領域を含む本明細書に記載されたような接着剤物品を提供する一つ以上の工程を含む。一般に、接着剤物品はドレッシングの形態である。また、上記方法は、患者の皮膚又は他の身体部位にわたって露出される傷部のような生物学的表面上に接着剤物品を塗布する一つ以上の工程を含む。上記物品は、接着剤層又は領域が傷部に向かっており、多数の適用において傷部に接触するように塗布される。上記言及された組成物の固有の流体処理特性の結果として、上記方法は傷治癒の促進、傷からの滲出液のような流体の吸収、及び傷周辺の流体の処理又は制御のうち一つ以上を達成する。
本発明の組成物を評価するために一連の実験が行われた。上記組成物は、接着剤成分、ゲル化剤、及び非ゲル化崩壊剤を含んでいる。接着剤は、Henkelから市販されるDUROTAK 129Aだった。ゲル化剤としては、様々なメーカーから市販されるA800カルボキシメチルセルロースが選択された。非ゲル化崩壊剤は、FMC Biopolymer製の商品名AVICEL PH105で入手可能な微結晶質セルロースから選択された。
PETフィルム上に直接コートされたり離型ライナーからPETフィルムに積層される接着剤のサンプルは、約2.54cm×20cmのテストストリップに切断した。接着剤サンプルは、ステンレススチール、HDPE又は約30cm/minの速度で前後に動く2kgゴムクラドスチールローラを具備したカードボードのテストパネル上に沿ってローリングされた。24時間の滞留時間後に、テストストリップをインストロン引張試験機のテストパネルから180゜剥離してテストパネルを、すなわち自体的にそして上記パネルの表面と平行に折り返した。テストパネルから接着ストリップを除去する力は、ニュートン/メートル(N/m)で測定された。テストを3回行って平均値を作成した。
水蒸気透過率(MVTR)、静的吸収(SA)、及び流体処理能(FHC)を測定する方法は、T06/022(EN13726及びASTM E 96−80に相応する)に提示されており、一般的に以下のとおりである。
表1を参照すると、ゲル化剤及び非ゲル化崩壊剤を使用する実施例4〜6で、本発明に係る接着剤組成物は、例えば1320g/m2/24時間超過のような比較的高い水蒸気透過率(MVTRs);例えば1450g/m2/24時間超過のような比較的高い静的吸収特性;及び、例えば2000g/m2/24時間超過、所定の実施の形態において2200g/m2/24時間超過、一部の実施の形態において2600g/m2/24時間超過、特定の実施の形態において2800g/m2/24時間超過のような比較的高い流体処理能を示すということが分かる。
本明細書に言及される特許、出願、標準、及び物品はその全てが参照されて含まれる。
