Description
第1流路と、第2流路と、前記第1流路および前記第2流路の間に配置されたバルブと、を有し、前記バルブは、基板に配置された溝状弁座と、前記溝状弁座を覆う平板状の可撓性層と、を含み、前記バルブは、前記可撓性層と前記溝状弁座の内壁とが離れているときに前記第1流路および前記第2流路を連通し、前記可撓性層と前記溝状弁座の内壁とが接しているときに前記第1流路および前記第2流路の間を遮断する、流体取扱装置。
上記流体取扱装置と、前記バルブの可撓性層を押圧可能なバルブ用摺動部材と、を有する、流体取扱システム。
図3Aは、本実施の形態の流体取扱装置200の斜視図である。当該流体取扱装置200は、基板210および可撓性層220を有する。本実施の形態では、流体取扱装置200は透明材料で構成されており、図3Aでは、流体取扱装置200の内部構造および裏側の構造も破線で示している。流体取扱装置200は、図3Bに示すようにスペーサー312に重ねられた状態で、図3Cや図4に示すように流体取扱システム300のチップホルダー310内に収容される。スペーサー312には、流体取扱装置200の複数のウェル230に対応する位置にウェル230を収容可能な貫通孔が形成されている。
流体取扱システム300は、上記流体取扱装置(流路チップ)200を保持するためのチップホルダー310と、チップホルダー310に保持された流体取扱装置200のバルブ250の開閉を制御するためのバルブ制御部320と、チップホルダー310に保持された流体取扱装置200のポンプ260の動作を制御するポンプ制御部330と、を有する。また、本実施の形態の流体取扱システム300は、チップホルダー310内に配置された制御部360と、記憶部370と、筐体380と、をさらに有する。
上述の流体取扱装置200やこれを含む流体取扱システム300では、バルブ250およびポンプ260の両方を備えていたが、流体取扱装置やこれを含む流体取扱システムは、これらのうち、いずれか一方のみを有するものであってもよい。
以下、流体取扱システム100を用いて流体を取り扱う方法の一例を説明する。ここでは、図11A~図12Bの模式図を参照しながら、図中上の列の左から2番目のウェル230(以下「導入ウェル」ともいう)に収容されている液体を図中の下の列の左から2番目のウェル230(以下「取出ウェル」ともいう)に移動させる例を説明する。図11A~図12Bでは、流体取扱装置200の複数のバルブ250の近傍の領域を表側から見ている様子を示しており、ウェル230の外壁等は省略している。複数のバルブ250のうち、バルブ用摺動部材321の第1凸部322に押圧されている閉じた状態のバルブ250を黒塗りで示し、バルブ用摺動部材321の第1凹部323と対向している開いた状態のバルブ250を白塗りで示す。
以上のように、本実施の形態に係る流体取扱装置は、基板および平板状の可撓性層で構成されており、簡便な構成を有する。また、可撓性層を成形する必要がなく、基板と可撓性層との細かい位置合わせも不要である。さらに、可撓性層が成形されていないことから、基板および可撓性層を高温で接着することも可能であり、信頼性の高い流体取扱装置や流体取扱システムとすることができる。また、可撓性層が平板状であるため、流体取扱装置や、これを含む流体取扱システムの小型化も可能である。
