CONNECTION APPARATUS FOR A CHEMICAL SOLUTION FLOW PATH FOR CONTROLLING THE LEAKAGE OF THE CHEMICAL SOLUTION IN THE SEPARATION OF A CHEMICAL SOLUTION FLOW PATH

摘要

PURPOSE: A connection apparatus for a chemical solution flow path is provided to control the mixing of a chemical solution in the change over of a flow path by closing a first opening and a second opening which are formed in a first valve body chamber.;CONSTITUTION: A connection apparatus(11) for a chemical solution flow path includes a first connecting unit and a second connecting unit. The first connecting unit(10a) comprises a first chemical solution valve room(38a), a first valve body, and a penetration solution supply controlling valve. The first drug liquid valve room is connected with the first chemical solution flow path, a first connecting flow path, and a penetration solution supply flow path. The first valve opens and closes a first chemical solution opening which is simultaneously communicated with the first chemical solution flow path and is formed in the first inner wall surface of the first chemical solution valve room. The second connecting unit comprises a second chemical solution valve room, a second valve body, and a penetration slolution discharge controlling valve.;COPYRIGHT KIPO 2012
