Description
欧州特許出願公開第1527789号明細書には、膜層および異なる組成物を含む親水コロイド接着剤の少なくとも2つの層を含む構造体が記載されている。
a)第一の接着剤層の不連続相は、第二の接着剤層の不連続相中の親水コロイドに比べて、接着剤により高い水分吸収能力およびより高い初期水分吸収速度を与える親水コロイドを含んでおり、また
b)第二の接着剤層の不連続相は、第一の接着剤層の不連続相中の親水コロイドよりも、水分吸収後により高い凝集性を与える親水コロイドを含んでいる。
不連続相の質量を基準として、
40〜50質量%、好ましくは45質量%のカルボキシメチルセルロース(例えばカルボキシメチルセルロースナトリウム)、
15〜25質量%、好ましくは20質量%のペクチン、および
30〜40質量%、好ましくは33〜35質量%のゼラチン。
不連続相の質量を基準として、
35〜45質量%、好ましくは40質量%のグアーガム、
15〜25質量%、好ましくは20質量%のカルボキシメチルセルロース(例えばカルボキシメチルセルロースナトリウム)、および
35〜45質量%、好ましくは40質量%のゼラチン。
支持層は溶着(weldable)可能な物質であることができ、それによって他の品物または器具を支持層上に溶着することができる。
所望により、接着剤構造体はまた、曲線をなすくぼみを有しており、これは放射状のくぼみと交差している。
オパノールB12SFN、BASFのポリイソブチレン、分子量=60000〜80000
クレイトンD−1161NU、クレイトンポリマーのSISブロック共重合体
アクセルAF2881、AKZOのカルボキシメチルセルロースナトリウム
PBゼラチンのゼラチンUF220
ノルディスクゼラチンのグアーガムFG−200
コペンハーゲンペクチンのペクチンポモシン(Pectin Pomosin)LM12CG−Z/200

第二の接着剤層の組成物
第一の接着剤層の組成物
親水コロイド接着剤は、当技術分野でよく知られた方法に従ってZ−混合機中で成分を加熱することによって調製することができ、また層状接着剤構造体は国際公開第00/18545号パンフレット中に記載された方法に従って調製することができる。
研究DK151OS(フライブルグ倫理委員会(Freiburger ethic-kommision)によって承認された。研究コード:DK145OS、Feciコード:05/1609)において、64人の回腸造瘻術を受けたドイツ人が排出可能なバッグの付いた層状接着剤構造体を、対照製品、ホリスターインク(Hollister Inc.)の単層接着剤、モデルマフレックス「エアースペース技術」、と比較して試験した。この研究は、開かれた、無作為に選ばれた、比較に基づく、横断的な多施設研究である。この研究は、参加者は、層状接着剤では糜爛の体験がより少なかったことを示しており、層状接着剤では77%が少しの糜爛を体験したかもしくは糜爛がなく、そして対照製品では55%がそうであった。また、皮膚への即時の接着(粘着)は、層状接着剤では著しく良好であると思われることが83%によって体験されたが、一方対照製品では55%であり、同様に、層状接着剤を取り除くときの痛みは、対照製品に比べてより少なかった。
実施可能性研究DK153OS(2005年12月8日のオートノルマンディーでの生物医学における人間の保護諮問委員会(Comite Consulatatif de Protection des Personnes dans la Recherche Biomedicale de haute Normandie)によって、No.2005/031として承認された。)において、59人の回腸造瘻術を受けたフランス人が排出可能なバッグの付いた層状接着剤構造体を、対照製品、コンバテックのインビジクローズ付きエスティーム、と比較して試験した。この研究は、開かれた、無作為に選ばれた、比較に基づく、横断的な研究である。この研究は、皮膚への即時の接着(粘着)は、層状接着剤では「良好」もしくは「非常に良好」であることが93%の参加者によって認識されたが、これに比べてエスティーム接着剤では66%であった。使用中の接着はまた、層状接着剤では76%によって「良好」もしくは「非常に良好」であるとことが体験され、これはエスティーム接着剤で体験された45%に比べて著しく良好であった。即時の接着と使用中の接着は、初期の水分吸収速度と120分後の水分吸収に結びついている。この研究はまた、参加者が層状接着剤を使用した場合には、皮膚に残った接着剤残渣が顕著に少ないことを体験した。また、顕著に良好な安心感が、層状接着剤構造体で体験された。
実施可能性研究DK109OS(東地域科学倫理委員会(Regionale Videnskabsetiske Komite ΦST)によって承認され、資料番号:2005−2−07G)において、68人の結腸瘻造設術を受けたデンマーク人が閉じたバッグの付いた層状接着剤構造体を試験した。この製品を比較品である、ダンサック社の単層接着剤付きのノバ1に対して試験した。この研究は、無作為に選ばれた、比較に基づく、横断的な研究である。この研究は、皮膚への即時の接着(粘着)および使用中の接着は、層状接着剤構造体を用いた場合には、対照製品に比較して著しく良好であった(即時の接着p<0.0001および使用中の接着p<0.0175)。即時の接着と使用中の接着は、初期の水分吸収速度と120分後の水分吸収に結びついている。取り外す時の痛みはまた、対照製品に比べて顕著に少ないと認識され、全般的な安心感も良好であった。
研究DK145OS(フライブルグ倫理委員会によって承認された。研究コード:DK145OS、Feciコード:05/1609)において、69人の結腸瘻造設術を受けたドイツ人が閉じたバッグの付いた層状接着剤構造体を試験した。この製品を比較品である、ホリスターのモデルマフレックスに対して試験した。この研究は、無作為に選ばれた、比較に基づく、横断的な研究である。この研究は、皮膚への即時の接着(粘着)は、層状接着剤構造体を用いた場合には、対照製品に比較して著しく良好であった(p<0.0001)ことを示していた。
