Description
本発明は、第一に、体液を保管するための容器、特に、体液を収容するための内部空間と、内部空間を取り囲む壁とを有する採血管であって、容器の内部空間に面した壁の表面が接触面を形成し、接触面の少なくとも一部にプライマーコーティングが施されており、プライマーコーティングは、アジド基および官能基を有するパーフルオロフェニルアジド(PFPA)の形態のフッ素化カップリング剤から形成されている、容器に関する。
診断プロセスでは、血液やその他の体液(血管外液(EVF))中の定量的なバイオマーカーの濃度や活性、および細胞や粒子の形態を病歴と合わせて特徴づけることで、臨床診断上の判断を下すことができる。信頼性の高い意思決定を行うための前提条件は、血管から採取した後の血液やEVFの分析前の安定化、および分析までの生体外での貯蔵を可能な限り高度に行うことである。現在、体液から採取されたサンプルは、実際に分析されるまでガラス管やプラスチック管(通常はポリプロピレン(PP)製)に保管されている。ここで、体液が患者の身体から出た後、これらの体液、特に血液のすべての成分に数多くの変質プロセスが起こる。管内では、採取された体液が管の壁に接触することで、特にタンパク質の吸着、細胞の接着、および体液の凝固が生じる。数多くの異なる成分、(例えば血液中での)その濃度および活性を安定させるために、例えばEDTA、クエン酸塩、またはヘパリンといった添加剤を管に加えるのが通常の手順である。しかし、すべてのバイオマーカーにすべての添加剤が適しているわけではないため、治療を行う医師は、疑われる疾患に応じて特別な管を選択する必要がある。さらに、容器内での保持時間、耐熱性、またはさらには光への露出時間も非常に限られており、これを超えた場合にも同様に誤った分析結果になるおそれがある。また、例えばEDTA、クエン酸塩、またはヘパリンといった添加剤は、単に血液凝固を阻害することしかできない。その他の多くの劣化プロセスの態様を防ぐことは不可能である。
本発明の課題は、体液を保管するための代替的な容器であって、容器の接触面への第2のコーティングの結合を向上させるプライマーコーティングを特徴とする容器を開発することである。
冒頭に記載した体液を保管するための容器から出発して、プライマーコーティングの官能基にポリ(N-ビニルアミン-co-N-ビニルアセトアミド)から構成される共重合体が結合されていることにより、上記課題が解決される。
上述した本発明につき、以下に、図面に示されている例示的な実施形態を参照して詳説する。
