Abstract
Description
いくつかの場合に、臨床医は、カテーテル内に挿入された針および注射器を使用して挿入されたカテーテルを通して患者から血液を抜き出すカテーテルアセンブリから採血する。
これらの手法は、通常、採集された血液検体が検査実施の前に抜き出される中間装置として、針および真空の管を利用する。このように、これらの工程は、装置集約的(device intensive)であり、血液検体を得る、準備する、かつ検査するプロセスにおいて、多数の
装置を利用する。各付加的装置は、検査工程の時間およびコストを増大させる。
採血装置などの生体液採集装置を提供する。血液検体の採集後、採血装置は、血漿部分を細胞部分から分離することができる。分離後、採血装置は、血液検体の血漿部分を臨床現場即時検査装置へ移送することができる。また、本開示の採血装置は、血液検体の暴露を低減する閉鎖された採集および移送システムを提供し、検体安定剤との血液検体の高速混合を実現する。検体安定剤は、抗凝固剤、または、例えば、RNA、タンパク質検体、もしくは他の要素などの血液中の特定の要素を保存するように設計されている物質であり得る。採血装置は、採血装置から血液検査装置まで血漿部分の一部を閉鎖して移送するために血液検査装置と係合可能である。血液検査装置は、血漿部分を受け入れ、血液検体を分析し、検査結果を得るようになされている。
ハウジングは、移送ポートに隣接しており、流路と流体連通しているリザーバをさらに含む。また、装置は、ハウジングの内部に配設されている穿刺部材であって、穿刺部材がハウジングの内部に保持されている作動前位置と穿刺部材がハウジングの入口ポートを貫通しており、流路との流体連通をもたらす穿刺位置との間で移動するようにした穿刺部材を含む。また、装置は、流路内の入口ポートとリザーバとの間に配設されている分離部材を含み、吸上部材(wicking element)が流路内の入口ポートと分離部材との間に配設されている。
移送ポートと、流路とを有するハウジングとを含み、入口ポートと移送ポートとは流路を介して流体連通している。ハウジングは、移送ポートに隣接し、流路と流体連通しているリザーバをさらに画定している。また、装置は、ハウジングの内部に配設されている穿刺部材であって、穿刺部材がハウジングの内部に保持されている作動前位置と穿刺部材がハウジングの入口ポートを貫通し流路との流体連通をもたらす穿刺位置との間で移動するようにした穿刺部材を含む。装置は、流路の内部の入口ポートとリザーバとの間に配設されている分離部材と、流路の内部の入口ポートと分離部材との間に配設されている吸上部材とをさらに含む。また、システムは、生体液採集装置のリザーバから血液検査装置まで多成分血液検体の成分の少なくとも一部の閉鎖された移送のために生体液採集装置の移送ポートに係合するようになされている受け口を有する血液検査装置を含む。
開放されたシステムを用いて手作業で採集され、一貫性のない結果、または、検体採集および検査プロセスの繰返しにつながるカートリッジの誤りの原因となることが多い手作業で臨床現場即時検査カートリッジに移送され、それにより、臨床現場即時検査装置の利点を無にする。したがって、ニーズが、より安全な、再現性のある、より正確な結果をもたらす、検体を採集し臨床現場即時検査装置に移送するシステムについて存在する。したがって、本開示の臨床現場即時採集および移送システムが、以下に説明される。本開示のシステムは、1)サンプリングおよび移送システムのより閉鎖されたタイプを組み込むこと、2)検体の開放暴露を最小限にすること、3)検体の質を向上させること、4)全体的な使い易さを向上させること、および、5)採集時点で検体を分離することにより、臨床現場即時検査装置の信頼性を高める。
分離し、次いでさらなる操作なしに、血漿部分を臨床現場即時検査装置22へ即刻移送してもよい。これは、血液への暴露のない、血漿の採集および臨床現場即時検査装置22への移送を可能にする。さらに、少量の血液のみを必要とする検査のために、それは、真空の管を用いた採血および血漿分離に関連する無駄を省く。また、本開示の採血装置10は、ランセットで切開すること、採血、および血液分離のコンセプトを組み込んでいる。
穿刺端部112は、患者の皮膚表面S(図2)を穿刺することに適合されており、尖った端部、刃先、または同様の切断機構を画定していてもよい。穿刺端部112は、刃の尖った端部が特定の向きで位置合わせされているように、好適な位置合わせ向きを含んでいてもよい。
ハウジング30の出口ポート42を受け入れ、血液検体を分析し、検査結果を得るようになされている。臨床現場即時検査装置22の受け口24は、ハウジング30の出口ポート42から臨床現場即時検査装置22への血液検体の閉鎖された移送を可能にする。
それがフィルタ52を通過して血漿を隔離する前に、血液に添加される。検体安定剤50は、吸上部材46に、フィルタ52の上方、内部、もしくは最上部の被覆層に、またはそれらの何らかの組合せのいずれかに含有されている。したがって、血液は、それが採血装置10のこれらの点を通過する際、検体安定剤50を獲得し、それと混合する。図3を参照すると、ランセット60が作動して皮膚表面Sを穿刺すると、スティック部位と採血装置10のハウジング30との間で血液が漏れ出さないかまたは最小限の血液が漏れ出し、重要なことに、任意の漏れ出した血液がその後に採血装置10に進入しない。
白血球、および赤血球がフィルタ52内に捕らえられ、捕捉され、浄化された血漿のみがフィルタ52を通過し、それが臨床現場即時検査装置22内へ分配されるまでの含有のために、採血装置10の内部の退出リザーバ54に進入することを可能にする。
本開示が関連し添付の請求の範囲の制限内に入る本技術分野の既知の実践または慣行の範囲内に入り本開示からそのようにずれた部分を包含することが意図されている。
