Description
図1は第1実施形態に係る細胞捕捉デバイスを含む細胞捕捉装置の構成を説明する図である。細胞捕捉装置は、被検液である血液をフィルタによってろ過することで血液中に含まれる細胞を捕捉する装置である。また、フィルタにより捕捉された細胞について、染色液等の処理液を用いて染色することで、細胞の特定及び細胞の個体数のカウント等が行われる。以下の実施形態では、被検液が血液であり、捕捉対象となる細胞が血中循環がん細胞(Circulating Tumor Cell:CTC)である場合について説明するが、この点については限定されない。例えば、被検液としては、血液、リンパ液等が挙げられ、捕捉対象となる特定の細胞としては、CTCを始めとする希少細胞、循環内皮細胞(Circulating endothelial cells:CEC)、血管循環内皮前駆細胞(Circulating endothelial progenitor cells:CEP)等が挙げられる。
次に、第1実施形態に係る細胞捕捉デバイス1について、図2〜図6を用いて説明する。図2は、細胞捕捉デバイスの外観斜視図であり、図3は、細胞捕捉デバイスの正面からの構成図であり、図4は、細胞捕捉デバイスの上面からの構成図であり、図5及び図6は、細胞捕捉デバイスの分解斜視図である。
次に、第2実施形態に係る細胞捕捉デバイスについて、図7〜図11を参照しながら説明する。図7は、細胞捕捉デバイスの外観斜視図であり、図8は、細胞捕捉デバイスの正面からの構成図であり、図9は、細胞捕捉デバイスの上面からの構成図であり、図10及び図11は、細胞捕捉デバイスの分解斜視図である。
次に、第3実施形態に係る細胞捕捉デバイスについて、図13〜図16を参照しながら説明する。図13は、細胞捕捉デバイスの正面からの構成図であり、図14は、細胞捕捉デバイスの上面からの構成図であり、図15及び図16は、細胞捕捉デバイスの分解斜視図である。
