Abstract
Description
図1は実施の形態で例示される流路デバイス100を示す平面図である。流路デバイス100は、処理用デバイス1と、接続デバイス2と、分離デバイス3とを備える。処理用デバイス1、接続デバイス2、分離デバイス3は、この順にZ方向へ向かって、互いに積層される。
流路デバイス100の機能は大まかには下記のように説明される。
図14は、図13と同様に、ステップS7の処理が終了した直後の状況を示す。但し、図14および図20においては、領域S,Tが互いに異なるハッチングを用いて示される。領域Sにおける流体は、領域Tにおける流体よりも分離対象粒子P100を多く含む。図14においては流路117が計測流路151と接続される位置71が示される。位置71は導入孔129から離れる場合が例示される。
計測流路151は、面1a,1bのいずれにも開口せず、第1孔である導入孔129と接続されて導入孔129と連通する第1溝であり;
流路116,117は纏まって、面1a,1bのいずれにも開口せず、(第1溝である)計測流路151と接続されて第1溝(計測流路151)と連通する第2溝であり;
攪拌流路115Aは、面1a,1bのいずれにも開口せず、(第1溝である)計測流路151と離れた(第2溝である)流路116,117の纏まりの途中の位置56で第2溝に接続されて第2溝(流路116,117の纏まり)と連通する第3溝であり;
第1溝(計測流路151)は第1孔(129)に関して第2溝(流路116,117の纏まり)とは反対側(ここでは(-Y)方向側)にも延び;
平面視上、第1孔の側で第2溝と第3溝とが成す劣角θ1(第1劣角ともいう)は、第1孔とは反対側で第2溝と第3溝とが成す劣角θ2(第2劣角ともいう)よりも大きい。
図20(b)は処理用デバイス1における攪拌流路115Aを攪拌流路115Bに置換した構成を示す。但し流体の図示は省略された。攪拌流路115Bは、面1a,1bのいずれにも開口しない溝である。攪拌流路115Bは上述の第3溝であるということもできる。
