Description
一実施形態によれば、本発明は、生体吸収性足場かマトリックス上に止血促進剤を含有する、或いはオプションとして凍結乾燥止血促進剤を含有する、止血用パッドを対象とする。好ましい止血足場材の例は、天然の又は遺伝子工学的に加工された生体吸収性ポリマーあるいは合成生体吸収性ポリマー、もしくはこれらの混合物である。
上記引用文献、米国特許出願公開第2009/0246238 A1号及び欧州特許公開第EP第2,052,746 A2号に記載されたものと同様の手順に従って、ポリ(グリコリド−コ−ラクチド)(PGLA、90/10mol/mol)を溶融紡糸して繊維を得た。80デニールのマルチフィラメント糸を統合処理して800デニールの統合糸を得た。その統合糸を約110℃でクリンプ加工した。このクリンプ加工糸を、約3.18cm(1.25”)長のステープルに切断し、20グラムのクリンプ加工ステープルを正確に秤量して、マルチローラー梳綿機(カーディング機械)の供給コンベヤベルト上に一様に配列した。環境条件(温度:21℃/55% RH)を制御した。次に、ステープルをカーディングして不織布バットを作製した。そのバットを収集ローラーから取り取り出し、等しい4つの部分に切断した。それらのバットを、取り出し方向と直角な方向のカーディング機械に再度送り込んだ。この第2パスの後、バットを秤量し(19.8g:布地収率99%)、次に圧縮した。縮したフェルトを、ORC布地上に正確に並べ、ニードルパンチによってしっかり固着した。この多層布をトリミングし、別個の3つのイソプロピルアルコール浴で洗浄してスピン仕上げ及び全ての機械油を除去した。次に、洗浄した多層布地をオーブン中で30分間70℃で乾燥し、冷却した後に秤量した。
a)フィブリノゲン及びトロンビンを含んでいる生物製剤含有止血用パッド、
b)フィブリノゲン、トロンビン及びPEGを含有する生物製剤含有止血用パッド、
c)フィブリノゲン、トロンビン、PEG及びCMCを含有する生物製剤含有止血用パッド。
下記のように種々異なるレベルの活性成分の濃度を用いて実験を行った:
BAC−2フィブリノゲン含有粉末:フィブリノゲン5.0及び6.7mg/cm2又はフィブリノゲン含有BAC−2粉末1.27g及び1.7g/10.2×10.2cm(4×4”)生物製剤含有止血用パッド試料
下記のようにして漏れ試験行った。生物製剤含有止血用パッドの試料を、3分間圧縮重しの下で豚血漿中で養生した。その後、試料を4.5mm径の穴がある平坦な金属製固定具上に載置し、上記と整合する穴を持つ透明なプラスチック天板を生物製剤含有止血用パッド上に全面にわたって固定した。次に、試料を、一定流量で穴から液圧流体として送り出される豚血漿に曝した。従って、唯一可能な欠陥態様は漏れだけで、漏れを生じたピーク圧力を出力として記録した。したがって、漏れは許容される唯一の故障モードであった、またピーク圧力は出力として記録された。
次に、表3及び図3を参照すると、生物製剤含有止血用パッド取り扱い作業後におけるPEG3000の4つの異なる濃度(0、100、200及び400mg、濃度はすべて10.2×10.2cm(4”×4”)生物製剤含有止血用パッド試料を基準として)に対する破砕性試験の結果が示されている。
試料がフィブリノゲン溶液を凝結させる時間を測定するフィブリンゲル化試験(傾斜管法)を下記のようにして行ったフィブリノゲン(ERL FIB3)を、濃度10mg/mLで200のmMトリス(Tris)緩衝食塩水に溶解させた。本発明の生物製剤含有止血用パッド又は対照の生物製剤含有止血用パッド試料(サイズ1cm2)12×75mmの硼珪酸ガラス管の底に置いた。管内の試料は、コーティング面側を上に向けた。その後、10mg/mLのフィブリノゲン溶液2mLをガラス管中に添加し、カバーをかけた後直ちに37℃水浴中の試験管立て立てた。ガラス管を10秒ごとに手で逆さまにした後、水浴内の試験管立てに戻す操作を行った。ガラス管を逆さまにする都度観察を行い、完全なゲル生成が観察された時、すなわち管中に明らかなバルク状の液体移動が認められなくなった時を観察の終点とした。
下記のようにして水進入の研究を行った。約1cm2サイズの生物製剤含有止血用パッド試料をその有効コーティング面にシリンジにより供給される水滴に曝した。その後、水滴が毛管作用によって試料中に入り込む時間を測定した。
