Abstract
Description
本開示は、概して、生物学的流体との使用のために適合されるデバイスに関する。より詳細には、本開示は、生物学的流体の構成成分を分離するために適合されるデバイスに関する。
血液試料採取(Blood sampling)は、患者からの少なくとも1滴の血液の採取を含む、一般的な健康管理手順である。血液試料は、一般に、入院させられた、在宅医療の、および救急室の患者から、指穿刺、かかと穿刺、または静脈穿刺のいずれかによって採取される。血液試料は、また、静脈ラインまたは動脈ラインによって、患者から採取されてもよい。いったん収集されると、血液試料は、例えば化学的組成、血液学(hematology)、または凝固(coagulation)を含む医学的に有用な情報を得るために分析されてもよい。
