Description

【0001】
【発明の属する技術分野】
本発明は、人工肛門や人工膀胱を有する人たちのストーマ,瘻孔,開孔部(以下ストーマという)に被着して、***物が直接皮膚に接しないまたは接しても皮膚炎やカブレを抑えることのできるストーマ用の皮膚保護材,または褥瘡等の瘡面に貼付して瘡傷部を保護することのできる瘡傷用の皮膚保護材に関するものである。
【0002】
【従来技術及び発明が解決しようとする課題】
従来、人工造瘻手術を受けた人たちはストーマからの***物を納める様々なパウチ(袋)を装着している。このパウチをストーマ周辺の皮膚面に取り付ける手段として、カラヤ−グリセロールゲルやカルボキシメチルセルロース等の水膨潤性物質(親水性物質)からなるリングまたはワッシャーが用いられる。そしてこれらのリングまたはワッシャーの欠点は、皮膚への粘着力が弱く,密閉性を保持することが困難であることと、この密閉性の悪さによってストーマからの***物等が直接皮膚に接し、皮膚の炎症やカブレを引き起こす点にある。
【0003】
この欠点を防止するために、これまでいろいろな試みがなされている。例えば、特開昭54−4491号公報には、微粉状セルロース,不溶性架橋デキストラン,Na−CMC等の接着力増強剤である感圧接着成分とハイドロコロイドと鉱油の混合物からなる医療用接合剤が開示されている。
【0004】
しかし、この医療用接合剤は、密閉性は改良されるものの、弾性に乏しく,体動についていけないために使用中にシワが入ったり,その部分が腰折れして裂けてしまうという欠点がある他、保管時や使用中に流動を起こし、本来の目的を達し得ないという欠点もある。
【0005】
また、特開昭57−169414号公報(特公昭63−6020号)には、粘着性ゴム様接合剤とハイドロコロイド(親水コロイド)とホワイトカーボン又は炭酸カルシウムのフロー性改良剤との三者混合物からなる皮膚保護材が開示されている。
【0006】
しかし、この皮膚保護材は、ハイドロコロイド(親水コロイド)と水に不溶性の弾性結合剤とフロー防止剤とを三者ブレンド(混練)した粘着性ゴム様接合剤からなるものであるため、硬度や粘着力は改善できるものの流動性が大きいという欠点がある。この流動性を改善しようとしてフロー防止剤を大量に加えれば硬度が高くなって弾性に乏しく、体動についていけないものとなり、これを防止しようとすればフロー防止剤の添加量を一定に抑えねばならず、勢い流動性の改善が小幅になるなど、流動性の改善に限界がある。
【0007】
さらに、特開平1−99564号公報には、ポリマーフィルム,織布,不織布,ポリマーフォームなどの支持材を弾性結合剤と水膨潤性物質と薬学的活性成分との混合物からなる感圧粘着剤層の一方の面に貼り合わせた瘡傷面を保護する薬学的活性成分含有粘着包帯が開示されている。
【0008】
しかし、この粘着包帯は、その粘着剤層が特開昭57−169414号公報(特公昭63−6020号)の接合剤と同様、水膨潤物質(水溶性高分子)と疎水性の弾性粘着物質とをブレンド(混練)した組成物からなっているので、特開昭54−4491号公報のものやハイドロコロイド物質のカラヤ組成物のみからなるものと比べると、粘着力は良くなって体動に追従しやすくなるため、瘡面への密閉性がよくなるが親水性物質を含有するために粘着剤層の流動性や軟化やベトつきを完全に防ぐことはできず、包帯を剥がした後も瘡面やストーマ周辺皮膚に粘着剤が残るなどの欠点がある。
【0009】
本発明は上述のようなストーマ用及び瘡傷用の皮膚保護材に要求される機能、即ち皮膚への密閉性が良いこと、カブレにくいこと、流動(フロー)しにくいこと、剥離時に皮膚への糊残りがないこと等を全て備えたストーマ用及び瘡傷用の皮膚保護材を得ることを目的とするものである。
【0010】
【課題を解決するための手段】
本発明は、ゴム系、アクリル系、シリコーン系、ウレタン系、ビニルアセテート系、熱可塑性ゴム系、又は液状ゴム系の弾性ポリマーを主成分とし、粘着付与剤、充填剤、顔料等の添加剤を添加した、20℃でのクリープが正数値で5mm/時間以下の凝集力を有する疎水性粘着剤からなる層の片面上に上記弾性ポリマーと水溶性高分子を7/3〜3/7の割合で混合した混合成分を主成分とする親水性粘着剤からなる層を積層して成ることを特徴とするストーマ用又は瘡傷用の皮膚保護材を用いて、該皮膚保護材の親水性粘着剤からなる層の露出面を瘡面やストーマ周辺皮膚へ貼着するという手段をとることにより、柔軟性,密着性,吸水性を有する親水性粘着剤からなる層が、瘡面やストーマ周辺皮膚への密着性を高めて長期間の使用でも確実に密着させることができるし、また瘡面やストーマ周辺皮膚の分泌液を吸収して菌の培地になることもないし、さらに体動に追随しやすく物理的刺激を皮膚面に与えないのでカブレにくいし、また親水性粘着剤からなる層に積層させた疎水性粘着剤からなる層がその凝集力により親水性粘着剤からなる層を保持して剥離時の親水性粘着剤からなる層の破壊による皮膚への糊残りを防ぎ、皮膚保護材を容易に剥がすことができる。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図面により詳述する。
図1は疎水性粘着剤からなる層の片面上に親水性粘着剤からなる層を積層した本発明皮膚保護材の一例を示す斜視図、図2は布帛または不織布を内在させた疎水性粘着剤からなる層の片面上に親水性粘着剤からなる層を積層した本発明皮膚保護材の一例を示す斜視図、図3は疎水性粘着剤からなる層の片面上の周辺部を除く所望の箇所に当該疎水性粘着剤からなる層より小さな表面積を持つ親水性粘着剤からなる層を積層した本発明皮膚保護材の一例を示す斜視図、図4は疎水性粘着剤からなる層の片面上の周辺部を除く所望の箇所に当該疎水性粘着剤からなる層より小さな表面積を持つ親水性粘着剤からなる層を積層し、さらに親水性粘着剤からなる層上に治療材を積層した本発明皮膚保護材の一例を示す斜視図、図5は疎水性粘着剤からなる層と親水性粘着剤からなる層に複数の溝を設けた本発明皮膚保護材の一例を示す斜視図、図6は疎水性粘着剤からなる層と親水性粘着剤からなる層とが積層された部分の略中央部に疎水性粘着剤からなる層と親水性粘着剤からなる層を貫通する孔を設けた本発明皮膚保護材の一例を示す斜視図、図7は瘡面に貼着して瘡傷部を保護する本発明皮膚保護材の使用例図、図8はパウチ(袋)に取り付けた本発明皮膚保護材の用途例図である。
【0012】
なお、図中1は親水性粘着剤からなる層、1aは親水性粘着剤からなる層1に設けた複数の溝、2は親水性粘着剤からなる層の保護材、3は疎水性粘着剤からなる層、3aは疎水性粘着剤からなる層3に設けた複数の溝、3bは疎水性粘着剤からなる層3に内在する布帛または不織布、4は離形紙、5は疎水性粘着剤からなる層の保護材、6は親水性粘着剤からなる層1と疎水性粘着剤からなる層3を貫通する孔、7はパウチ(袋)、8は消臭剤孔、9は識別票、10は治療材である。
【0013】
即ち、本発明は、図1〜図6に示すように疎水性粘着剤からなる層3の片面上に親水性粘着剤からなる層1を積層して得られる2層構造を含む皮膚保護材である。
【0014】
本発明は、20℃におけるクリープが正数値で5mm/時間以下(JISZ−0237)の凝集力を有する疎水性粘着剤からなる層3に親水性粘着剤からなる層1を積層した皮膚保護材であって、このような皮膚保護材は従来の親水性粘着剤からなる層単独の使用と異なり、分泌液の水分を吸収した場合にも型くずれを起こしたり,必要以上にベトついたり,過剰な流動(フロー)をし始めたり,これを引き剥がすときにその凝集力を失って皮膚に残るなどの欠点を全て克服できる。
【0015】
即ち、一般に凝集力の弱い親水性粘着剤からなる層1のみからなる皮膚保護材が瘡傷部やストーマ周辺部に貼着された場合には、体温による昇温や分泌液の吸収あるいは貼着時のわずかなテンションなどで親水性粘着剤からなる層1が軟化して型くずれを起こしたり,流動(フロー)したり,ベトついたりしがちである。
【0016】
しかし、皮膚保護材が次のような2層構造を含む場合、即ち、一方の層を構成する粘着剤が20℃のクリープが正数値で5mm/時間以下(JISZ−0237)という他方の層を構成する親水性粘着剤の凝集力よりもはるかに大きい凝集力を有する疎水性の粘着剤であって、しかも2層間の粘着力がどのような場合にも親水性粘着剤からなる層1と被着体間のそれよりも大きくなるように積層された2層構造を含む場合には、疎水性粘着剤からなる層3が親水性粘着剤からなる層1を皮膚に追随する程度の柔軟性を保ちつつ弾力的に固定して親水性粘着剤からなる層1の軟化や型くずれや過剰な流動(フロー)を抑えることができる。さらに剥離時には、親水性粘着剤からなる層1は凝集力の大きい疎水性粘着剤からなる層の側に引っ張りあげられて被着体に糊残りを起こさせることなく簡単に剥離することができる。
【0017】
ここにおいて、疎水性粘着剤からなる層3を構成する疎水性粘着剤は、NR,IR,BR,IIR,EPR,CR,NBR,SBR,ポリイソブチレン等のゴム系,アクリル酸アルキルエステル共重合体,エチレンメチルアクリレート共重合体等のアクリル系,ジメチルシロキサン,メチルビニルシロキサン,フェニルメチルシロキサン,フェニルビニルメチルシロキサン,フッ化シリコーン等のシリコーン系,ポリエステルウレタン,ポリエーテルウレタン等のウレタン系,エチレン酢酸ビニル共重合体,酢酸ビニル共重合体等のビニルアセテート系,SBS,SIS,SEBS,SEPS,ポリエステルウレタン,ポリエーテルウレタン,ポリエーテルポリエステルブロック共重合体,ポリオレフィンブロック共重合体,トランス1.4ポリイソプレン,ポリエチレンブチルグラフト共重合体等の熱可塑性ゴム系,又はポリブタジエン,ポリクロロプレン,ポリイソプレン,ポリ1.3ペンタジエン,ポリシクロペンタジエン,ポリブテン等の液状ゴム系から選択された弾性ポリマーを主成分とし、要すれば粘着付与剤,充填剤,顔料等を添加して得られる。
【0018】
さらに、疎水性粘着剤からなる層3を構成する疎水性粘着剤は、溶剤系,水系,液状ポリマー系,ドライブレンド系(シーラント系),ホットメルト系のいずれの材料形態でもよく、それぞれの形態に合わせて離形処理されたプラスチックフィルムまたは離形紙からなる疎水性粘着剤からなる層の保護材5上にコーティング,押出し,プレス,圧延(カレンダリング)されるか、コーティング,押出し,プレス,圧延後に前記保護材5と貼り合わされるか、転写される。
【0019】
一方、このようにして得られた疎水性粘着剤からなる層3の形状は、その原型がシート状,テープ状,フィルム状であって、他層である親水性粘着剤からなる層1と貼り合わされた後、打抜き加工やプレス加工や裁断加工などの方法により、方形,多角形,台形,長方形,円形,楕円形等所望の形状に形成することができるものである。
【0020】
さらにまた、このようにして得られた疎水性粘着剤からなる層3の厚みは2mm〜0.02mmが望ましい。この理由は、2mm以上に厚みを有する場合は、疎水性粘着剤からなる層3の自重や外圧によりこれ自体が型くずれや流動(フロー)を起こすおそれがあって好ましくないからであり、0.02mm以下では所望の粘着力が得にくく、親水性粘着剤からなる層1の軟化や型くずれや過剰な流動(フロー)を皮膚に追随する程度の柔軟性を保ちつつ弾力的に固定する力や図8の使用例に示すパウチ(袋)7への貼着力、さらには図7の識別票9を貼着する貼着力が弱くなり問題を起こしかねないからである。
【0021】
次に、親水性粘着剤からなる層1を構成する親水性粘着剤について述べれば、親水性粘着剤の組成物としては、上述した疎水性粘着剤に用いられる弾性ポリマーと、カラヤゴム,グアガム,アラビアゴム,キャロブゴム,ロッカストビーンゴム,カラギーナン,澱粉,ペクチン,ゼラチン,アルブミン,ナトリウムカルボキシメチルセルロース,カルシウムカルボキシメチルセルロース,カルボキシメチルセルロース,微結晶セルロース,キサンタンゴムなどの天然水溶性高分子,ポリアクリル酸,ポリビニルアルコール,ポリエチレンオキサイド,アルギン酸ナトリウム,アルギン酸カルシウムなどの合成水溶性高分子のうち一つまたは一つ以上を混合して得られる。
【0022】
なお、弾性ポリマーと水溶性高分子の混合比は3対7〜7対3の比率である。これは水溶性高分子の混合比が7割以上のものは体温や分泌液の吸収等によって必要以上に軟化しやすく、ベトつきやすい一方、3割以下のものは凝集力が大きくなりすぎ肌への密着性が悪くなる他、分泌液を吸収したり、体動に追随しにくくなるなど好ましくないからである。
【0023】
一方、この親水性粘着剤は、ニーダー等の混練機により弾性ポリマーと水溶性高分子要すれば薬剤等が均一に混合されて得られる。得られた混合物は、次にTダイ押出機や圧延ロールやプレス機でシート状に圧延され、離形処理されたプラスチックフィルムや離形紙からなる親水性粘着剤からなる層の保護材2に圧延と同時にまたは圧延の後に貼り合わされる。
【0024】
また、このようにして得られた親水性粘着剤からなる層1の厚みは0.5mm〜3mmが好ましい。これは親水性粘着剤からなる層1が0.5mm以下の厚みでは、パウチ(袋)をストーマ周辺の皮膚面に取り付けストーマからの***物を直接皮膚に接しないように、また外部に漏らさないようにパウチ(袋)へ収めるという、ストーマに被着する用途での皮膚保護材本来の目的を果たしにくいからであり、3mm以上の厚みでは過剰な流動(フロー)が起こりやすい他、自重による落下や装着時の違和感が大きいなどの欠点を有するからである。
【0025】
次に、上記親水性粘着剤からなる層1と疎水性粘着剤からなる層3の積層はこれら2つの粘着層を同時に複合押出機を用いて貼り合わせることができる他、それぞれを別々に形成して貼り合わせた後に方形,多角形,台形,長方形,円形,楕円形等の所望の形状に形成することもできる。またそれぞれを所望の形状に加工した後に貼り合わせて形成することも自由であるなど、要はこれら2つの粘着層が所望の形状で積層された2層構造をとりうるものであればいずれでもよい。
【0026】
なお、親水性粘着剤からなる層1の過剰な流動により親水性粘着剤からなる層1が疎水性粘着剤からなる層3面よりはみ出し、ひいては被着体からの剥離性を悪くすることを防ぐ工夫として、図3,図4に示すように疎水性粘着剤からなる層3の表面積を親水性粘着剤からなる層1の表面積よりも大きくした形状、即ち疎水性粘着剤からなる層3の片面上の周辺部を除く所望の箇所に該疎水性粘着剤からなる層3の表面積より小さな表面積を持つ親水性粘着剤からなる層1を積層して2層構造に形成することもできる。こうすることにより、親水性粘着剤からなる層1を疎水性粘着剤からなる層3で保持しやすいことは勿論のこと、親水性粘着剤からなる層1が万一体温や分泌液の吸収によって過剰な流動を起こしても、疎水性粘着剤からなる層3のエリアより外にはみ出ることがない。
【0027】
一方、疎水性粘着剤からなる層3の上述のような効果をより一層大きくするために、図2,図4に示すように疎水性粘着剤からなる層3には不織布や布帛3bを内在させることができる。こうすることによって、疎水性粘着剤からなる層3の凝集力を補い、親水性粘着剤からなる層1の過剰な流動性や剥離時の良好な剥離性を一層高めることができる。
【0028】
さらに、瘡傷部を保護する目的で使用される場合の本発明皮膚保護材にあっては、図4に示すとおり、親水性粘着剤からなる層1上に消炎鎮痛剤,局所抗炎症剤,止痒剤,抗疥癬剤,局所麻酔剤,抗細菌剤等の薬剤をしみこませたガーゼ等の治療材10を貼付して用いることもできる。また、前記の薬剤は親水性粘着剤からなる層1中に直接練り込むこともできるが、この場合にはガーゼ等の治療材10を省略することができる。さらにまた、通気性を要望される用途には、親水性粘着剤からなる層1と疎水性粘着剤からなる層3との両方を、または親水性粘着剤からなる層1のみを300g/m・24時間〜8000g/m・24時間の透湿度が得られるように設計する。これは、300g/m・24時間以下の透湿度では透湿度が不十分で、透湿機能を十分に果たし得ないからであり、8000g/m・24時間以上の透湿度はかえって大気中の湿気の吸湿を招くなど好ましくないからである。なお、上記の透湿度は、親水性粘着剤からなる層1または疎水性粘着剤からなる層3に機械的に細孔を設けるか、当該配合物中に親水性高分子水溶液を添加した後加熱乾燥することにより得ることができる。
【0029】
さらにまた、本願皮膚保護材は図5に示すように、疎水性粘着剤からなる層3または親水性粘着剤からなる層1あるいはその両方の瘡面やストーマ周辺皮膚に貼着される面それぞれに複数の溝1a,3aを設けることができる。これはひとつには貼着する皮膚面への接地面積を少なくして剥離を容易にするためであり、さらには粘着剤層の過剰な流動を厚み方向に逃がして幅や長さ方向へのはみ出しを防ぐためである。
【0030】
さらに、図7に示すように、瘡面に貼着して瘡傷部を保護する用途においては、瘡傷部に貼着後疎水性粘着剤からなる層の保護材5を剥離して識別票9を貼着して、識別を明らかにして用いることもできるし、疎水性粘着剤からなる層の保護材5に所望の識別表示を印刷しておきこれを識別票9として用いることもできる。
【0031】
一方、図8に示すように、パウチ(袋)に取り付けた後、このパウチ(袋)をストーマ周辺の皮膚面に取り付ける用途に用いる皮膚保護材には、例えば図6に示すように疎水性粘着剤からなる層3と親水性粘着剤からなる層1とが積層された部分の略中央部に疎水性粘着剤からなる層3と親水性粘着剤からなる層1とを貫通する孔6を設ける。この孔6は当然のことながらパウチ(袋)の孔及びストーマに連結されるものでなくてはならない。
【0032】
なお、図3〜図6に示す皮膚保護材の皮膚面への貼着は、親水性粘着剤からなる層の保護材2および疎水性粘着剤からなる層3に設けた離形紙4を剥がして貼着する。
【0033】
【実施例】
以下、本発明の実施例について述べる。
実施例1
表1に示す親水性粘着剤成分と表2に示す疎水性粘着剤成分をそれぞれニーダーで配合した。次に、配合した親水性粘着剤配合物と疎水性粘着剤配合物をそれぞれ押出機で厚さ1mmにシーティングした後、25cm×25cmの大きさに裁断し、加圧プレス機で両者を貼り合わせた後、150mmφに打ち抜き加工してサンプル1を得た。このサンプル1を試用に供したところ表3に示す結果を得た。
【0034】

【発明の効果】
本発明の皮膚保護材は、柔軟性,密着性,吸水性を有する親水性粘着剤からなる層が瘡面やストーマ周辺皮膚への密着性を高めて長期間の使用でも確実に密着させることができるし、また瘡面やストーマ周辺皮膚の分泌液を吸収して菌の培地になることもないし、さらに体動に追随しやすく物理的刺激を皮膚面に与えないのでカブレにくいし、また親水性粘着剤からなる層を積層させた疎水性粘着剤からなる層はその凝集力により親水性粘着剤からなる層を皮膚に追随する程度の柔軟性を保ちつつ弾力的に固定して親水性粘着剤からなる層の過剰な流動を防ぐと共に剥離時にもこの凝集力の保持により親水性粘着剤からなる層の破壊による皮膚への糊残りを起こさせることなく皮膚保護材を容易に剥がすことができるという効果が得られる。

BACKGROUND OF THE INVENTION
The present invention adheres to the stoma, fistula, and opening (hereinafter referred to as the stoma) of people who have an artificial anus or an artificial bladder to suppress dermatitis and blurring even if the excrement does not touch the skin or does not touch it. The present invention relates to a skin protective material for stoma that can be applied, or a skin protective material for pressure sores that can be applied to pressure ulcer surfaces such as pressure ulcers to protect the pressure ulcer.
[0002]
[Prior Art and Problems to be Solved by the Invention]
Conventionally, people who have undergone artificial surgery have been wearing various pouches (bags) to store the excrement from the stoma. As a means for attaching the pouch to the skin surface around the stoma, a ring or washer made of a water-swellable substance (hydrophilic substance) such as Karaya-glycerol gel or carboxymethylcellulose is used. The disadvantages of these rings or washers are that the adhesive strength to the skin is weak and it is difficult to maintain the sealing property, and due to this poor sealing property, the excrement etc. from the stoma directly contacts the skin. It causes inflammation and fogging.
[0003]
Various attempts have been made to prevent this drawback. For example, Japanese Patent Application Laid-Open No. 54-4491 discloses a medical bonding agent comprising a mixture of a pressure-sensitive adhesive component such as fine powdery cellulose, insoluble cross-linked dextran, and Na-CMC, a hydrocolloid, and a mineral oil. Has been.
[0004]
However, this medical bonding agent is improved in hermeticity, but lacks elasticity, and because it cannot keep up with body movements, it has the disadvantage that it wrinkles during use, and that part breaks and tears. There is also a drawback in that fluidity occurs during storage or use and the original purpose cannot be achieved.
[0005]
Japanese Laid-Open Patent Publication No. 57-169414 (Japanese Patent Publication No. 63-6020) discloses a ternary mixture of an adhesive rubber-like bonding agent, a hydrocolloid (hydrocolloid), and a flow improver of white carbon or calcium carbonate. A skin protection material is disclosed.
[0006]
However, this skin protection material is composed of a sticky rubber-like bonding agent obtained by blending (kneading) a hydrocolloid (hydrocolloid), a water-insoluble elastic binder, and an anti-flow agent. Although the power can be improved, there is a drawback of high fluidity. If a large amount of an anti-flow agent is added to improve the fluidity, the hardness becomes high and the elasticity is poor, and the body movement cannot be maintained. To prevent this, the addition amount of the anti-flow agent must be kept constant. However, there is a limit to the improvement of liquidity, such as the improvement of momentum liquidity becomes small.
[0007]
Further, JP-A-1-99564 discloses a pressure sensitive adhesive layer comprising a mixture of an elastic binder, a water-swellable substance and a pharmaceutically active ingredient as a support material such as a polymer film, woven fabric, non-woven fabric, and polymer foam. An adhesive bandage containing a pharmaceutically active ingredient for protecting a wound surface bonded to one surface of the adhesive is disclosed.
[0008]

[0013]
That is, the present invention is a skin protective material comprising a two-layer structure obtained by laminating a layer 1 made of a hydrophilic adhesive on one surface of a layer 3 made of a hydrophobic adhesive as shown in FIGS. is there.
[0014]
The present invention is a skin protective material in which a layer 1 made of a hydrophilic pressure-sensitive adhesive is laminated on a layer 3 made of a hydrophobic pressure-sensitive adhesive having a cohesive strength of 20 mm or less with a positive creep value of 5 mm / hour or less (JISZ-0237). Such a skin protection material is different from the conventional use of a single layer made of a hydrophilic adhesive, and when the moisture of the secretion is absorbed, it loses its shape or becomes excessively sticky or excessively fluid. (Flow) can be overcome, and all the drawbacks such as losing its cohesion and remaining on the skin when it is peeled off can be overcome.
[0015]
That is, in general, when a skin protective material consisting only of the layer 1 made of a hydrophilic adhesive having a low cohesive force is attached to the wound or stoma, the temperature rises due to body temperature, the secretion fluid is absorbed or attached. The layer 1 made of the hydrophilic pressure-sensitive adhesive tends to be softened due to a slight tension or the like, to be deformed, to flow, or to be sticky.
[0016]
However, when the skin protection material includes the following two-layer structure, that is, the pressure-sensitive adhesive constituting one layer has a positive 20 ° C creep value of 5 mm / hour or less (JISZ-0237). A hydrophobic pressure-sensitive adhesive having a cohesive force far greater than the cohesive force of the constituting hydrophilic pressure-sensitive adhesive, and the layer 1 made of the hydrophilic pressure-sensitive adhesive and the coated layer can be coated in any case. In the case of including a two-layer structure laminated so as to be larger than that between the wearing bodies, the layer 3 made of the hydrophobic pressure-sensitive adhesive is flexible enough to follow the skin of the layer 1 made of the hydrophilic pressure-sensitive adhesive. It is possible to suppress the softening, mold loss and excessive flow (flow) of the layer 1 made of a hydrophilic pressure-sensitive adhesive by being elastically fixed while being maintained. Furthermore, at the time of peeling, the layer 1 made of a hydrophilic pressure-sensitive adhesive can be easily peeled without being pulled up to the side of the layer made of a hydrophobic pressure-sensitive adhesive having a large cohesive force and causing an adhesive residue on the adherend.
[0017]
Here, the hydrophobic pressure-sensitive adhesive constituting the layer 3 made of the hydrophobic pressure-sensitive adhesive is NR, IR, BR, IIR, EPR, CR, NBR, SBR, polyisobutylene or other rubber-based, acrylic acid alkyl ester copolymer. , Acrylics such as ethylene methyl acrylate copolymer, dimethyl siloxane, methyl vinyl siloxane, phenyl methyl siloxane, phenyl vinyl methyl siloxane, silicones such as silicone fluoride, urethanes such as polyester urethane and polyether urethane, ethylene vinyl acetate Copolymer, vinyl acetate copolymer such as vinyl acetate copolymer, SBS, SIS, SEBS, SEPS, polyester urethane, polyether urethane, polyether polyester block copolymer, polyolefin block copolymer, transformer 1.4 The main component is an elastic polymer selected from thermoplastic rubbers such as lyisoprene and polyethylenebutyl graft copolymer, or liquid rubbers such as polybutadiene, polychloroprene, polyisoprene, poly1.3pentadiene, polycyclopentadiene, and polybutene. If necessary, it can be obtained by adding a tackifier, a filler, a pigment or the like.
[0018]
Further, the hydrophobic pressure-sensitive adhesive constituting the layer 3 made of the hydrophobic pressure-sensitive adhesive may be in any form of a solvent, water, liquid polymer, dry blend (sealant), or hot-melt material. Coating, extruding, pressing, rolling (calendering), coating, extruding, pressing, coating on the protective material 5 of a layer made of a hydrophobic adhesive made of a plastic film or a release paper that has been processed to release After rolling, the protective material 5 is pasted or transferred.
[0019]
On the other hand, the layer 3 made of the hydrophobic pressure-sensitive adhesive thus obtained has a prototype of a sheet shape, a tape shape, and a film shape, and is bonded to the layer 1 made of a hydrophilic pressure-sensitive adhesive that is another layer. After being combined, it can be formed into a desired shape such as a square, polygon, trapezoid, rectangle, circle, ellipse, etc. by a method such as punching, pressing or cutting.
[0020]
Furthermore, the thickness of the layer 3 made of the hydrophobic adhesive thus obtained is desirably 2 mm to 0.02 mm. The reason for this is that when the thickness is 2 mm or more, the layer 3 made of a hydrophobic pressure-sensitive adhesive may itself lose its shape or flow due to its own weight or external pressure. In the following, it is difficult to obtain a desired adhesive force, and the force of elastically fixing the layer 1 made of a hydrophilic adhesive while keeping the flexibility to follow the softening, deformation, and excessive flow (flow) of the layer is shown in FIG. This is because the sticking force to the pouch (bag) 7 shown in the example of use, and the sticking force to stick the identification tag 9 in FIG.
[0021]
Next, the hydrophilic adhesive constituting the layer 1 composed of the hydrophilic adhesive will be described. As the composition of the hydrophilic adhesive, an elastic polymer used for the above-mentioned hydrophobic adhesive, Karaya gum, guar gum, Arabic Natural water-soluble polymers such as rubber, carob rubber, rock cast bean rubber, carrageenan, starch, pectin, gelatin, albumin, sodium carboxymethyl cellulose, calcium carboxymethyl cellulose, carboxymethyl cellulose, microcrystalline cellulose, xanthan gum, polyacrylic acid, polyvinyl alcohol , Polyethylene oxide, sodium alginate, calcium alginate, and other synthetic water-soluble polymers.
[0022]
The mixing ratio of the elastic polymer and the water-soluble polymer is a ratio of 3 to 7 to 7 to 3. This is because water-soluble polymers with a mixing ratio of 70% or more tend to be softened and sticky more than necessary due to body temperature, absorption of secretions, etc. In addition to the poor adhesion, it is not preferable to absorb secretory fluid or to follow body movement.
[0023]
On the other hand, this hydrophilic pressure-sensitive adhesive is obtained by uniformly mixing an elastic polymer and a water-soluble polymer, if necessary, with a kneader such as a kneader. The obtained mixture is then rolled into a sheet by a T-die extruder, a rolling roll or a press, and formed into a protective material 2 for a layer made of a hydrophilic adhesive made of a release-treated plastic film or release paper. It is bonded together with rolling or after rolling.
[0024]
Further, the thickness of the layer 1 made of the hydrophilic adhesive thus obtained is preferably 0.5 mm to 3 mm. If the layer 1 made of hydrophilic adhesive has a thickness of 0.5 mm or less, a pouch (bag) is attached to the skin surface around the stoma so that excrement from the stoma does not directly contact the skin and does not leak to the outside. This is because it is difficult to achieve the original purpose of the skin protection material in the application to be attached to the stoma, that is, to put it in the pouch (bag). This is because it has drawbacks such as a great sense of discomfort when worn.
[0025]
Next, in the lamination of the layer 1 made of the hydrophilic pressure-sensitive adhesive and the layer 3 made of the hydrophobic pressure-sensitive adhesive, these two pressure-sensitive adhesive layers can be bonded together using a composite extruder at the same time. Can be formed into a desired shape such as a square, polygon, trapezoid, rectangle, circle, or ellipse. In addition, any of them can be used as long as they can take a two-layer structure in which these two adhesive layers are laminated in a desired shape, for example, they can be formed and bonded together after being processed into a desired shape. .
[0026]
It is to be noted that the layer 1 made of the hydrophilic pressure-sensitive adhesive prevents the layer 1 made of the hydrophilic pressure-sensitive adhesive from protruding from the surface of the layer 3 made of the hydrophobic pressure-sensitive adhesive and thus deteriorates the peelability from the adherend. As a device, as shown in FIGS. 3 and 4, a shape in which the surface area of the layer 3 made of hydrophobic adhesive is larger than the surface area of the layer 1 made of hydrophilic adhesive, that is, one side of the layer 3 made of hydrophobic adhesive A layer 1 made of a hydrophilic pressure-sensitive adhesive having a surface area smaller than the surface area of the layer 3 made of the hydrophobic pressure-sensitive adhesive can be laminated at a desired location excluding the upper peripheral portion to form a two-layer structure. By doing so, the layer 1 made of the hydrophilic pressure-sensitive adhesive can be easily held by the layer 3 made of the hydrophobic pressure-sensitive adhesive. Even if an excessive flow occurs, it does not protrude beyond the area of the layer 3 made of a hydrophobic adhesive.
[0027]
On the other hand, in order to further increase the above-described effects of the layer 3 made of the hydrophobic adhesive, the nonwoven fabric or the fabric 3b is incorporated in the layer 3 made of the hydrophobic adhesive as shown in FIGS. be able to. By doing so, the cohesive force of the layer 3 made of the hydrophobic pressure-sensitive adhesive can be supplemented, and the excessive fluidity of the layer 1 made of the hydrophilic pressure-sensitive adhesive and the good peelability at the time of peeling can be further enhanced.
[0028]
Furthermore, in the skin protection material of the present invention used for the purpose of protecting the wound part, as shown in FIG. 4, an anti-inflammatory analgesic, a local anti-inflammatory agent on the layer 1 made of a hydrophilic adhesive, A therapeutic material 10 such as gauze impregnated with a drug such as an antidiarrheal agent, an anti-scabies agent, a local anesthetic agent, or an antibacterial agent can also be used. Moreover, although the said chemical | medical agent can also be kneaded directly in the layer 1 which consists of hydrophilic adhesives, in this case, therapeutic materials 10, such as gauze, can be abbreviate | omitted. Furthermore, for applications where air permeability is required, 300 g / m 2 of both the layer 1 made of a hydrophilic pressure-sensitive adhesive and the layer 3 made of a hydrophobic pressure-sensitive adhesive, or only the layer 1 made of a hydrophilic pressure-sensitive adhesive. Designed to obtain a moisture permeability of 24 hours to 8000 g / m 2 · 24 hours. This is because the moisture permeability of 300 g / m 2 · 24 hours or less is insufficient, and the moisture permeability function cannot be sufficiently achieved. The moisture permeability of 8000 g / m 2 · 24 hours or more is rather in the atmosphere. This is because it is not preferable to cause moisture absorption. The moisture permeability is determined by mechanically providing pores in the layer 1 made of a hydrophilic pressure-sensitive adhesive or the layer 3 made of a hydrophobic pressure-sensitive adhesive, or heating after adding a hydrophilic polymer aqueous solution to the compound. It can be obtained by drying.
[0029]
Furthermore, as shown in FIG. 5, the skin protecting material of the present application is applied to each of the surfaces attached to the pressure sore surface and the stoma surrounding skin of the layer 3 made of a hydrophobic adhesive and / or the layer 1 made of a hydrophilic adhesive. A plurality of grooves 1a and 3a can be provided. This is partly to reduce the contact area to the skin surface to be applied and facilitate peeling, and to release excess flow of the adhesive layer in the thickness direction and to protrude in the width and length directions. Is to prevent.
[0030]
Furthermore, as shown in FIG. 7, in the use which protects a wound part by affixing on a sore surface, the protective material 5 of the layer which consists of hydrophobic adhesives is peeled off after attaching to a sore part, and an identification tag is peeled off. 9 can be used by clarifying the identification, or a desired identification display can be printed on the protective material 5 of the layer made of a hydrophobic adhesive and used as the identification tag 9.
[0031]
On the other hand, as shown in FIG. 8, the skin protective material used for attaching the pouch (bag) to the skin surface around the stoma after being attached to the pouch (bag) is, for example, a hydrophobic adhesive as shown in FIG. A hole 6 that penetrates the layer 3 made of a hydrophobic adhesive and the layer 1 made of a hydrophilic adhesive is provided at a substantially central portion of a portion where the layer 3 made of the agent and the layer 1 made of the hydrophilic adhesive are laminated. . Naturally, this hole 6 must be connected to the hole and stoma of the pouch (bag).
[0032]
3 to 6 are peeled off the release paper 4 provided on the protective material 2 of the layer made of hydrophilic adhesive and the layer 3 made of the hydrophobic adhesive. And stick.
[0033]
