第2流路デバイス3は、第1流路デバイス2で分離して回収した特定の粒子を計測するための流路デバイスであり、第1流路デバイス2とともに粒子分離計測デバイス1を構成するものである。この第2流路デバイス3は、第1流路デバイス2が載置される第1領域21および特定の粒子の計測領域となる第2領域22を有し、第1流体が流入する第1流入口23、後述する特定の粒子を含まない第2流体が流入する第2流入口、ならびにそれぞれ第2領域22に配置された、第1流入口23に接続されて第1流体が通過する第1流路16および第2流入口に接続されて第2流体が通過する、後述する第2流路を有しており、全体として板状である。
第1流路デバイス2は、第2流路デバイス3の第2上面19の第1領域21に載置されている。そして、第1流路デバイス2の分離後流出口13と、第2流路デバイス3の第1流入口23とが、対向して接続されている。そして、本開示においては、図5に示すように、第1流入口23の第2開口18の大きさは、分離後流出口13の第1開口9の大きさよりも大きい。その結果、第1流路デバイス2と第2流路デバイス3との接続部において、第1流体の滞留を低減することができる。なお、分離後流出口13の開口の大きさは、例えば0.5〜3mm、好適には2mm程度であればよく、第1流入口23の開口の大きさは、例えば1.5〜6mm、好適には5mm程度であればよい。
次に、本開示の粒子分離計測装置における粒子分離装置について説明する。本開示の粒子分離装置は、粒子分離デバイスである第1流路デバイス2と、分離前流入口12に検体を流入させるための第1ポンプおよび押付流入口15に流体を流入させるための第2ポンプとを有する。粒子分離デバイスは上述の第1流路デバイス2であり、第1流路デバイス2の分離前流入口12に第1ポンプが例えば第1チューブで接続されている。そして、第1ポンプから送られた検体は、第1チューブを通って第1流路デバイス2の分離前流入口12へ流入する。また、第1流路デバイス2の押付流入口15に第2ポンプが例えば第2チューブで接続されている。そして、第2ポンプから送られた流体は、第2チューブを通って第1流路デバイス2の押付流入口15へ流入する。それにより、上述のように、主流路5と複数の分岐流路6とによって検体中から特定の粒子、例えば第1粒子P1を分離して回収することができる。
