Abstract

PURPOSE:To stably collect plasma without diluting collected plasma with a priming liquid, by detecting the blood removing amount, before the blood corpuscle component allowed to fill a membrane module is replaced with blood at the time of the removal of blood, by the first detector. CONSTITUTION:When a control apparatus 40 is operated and an ACD pump 27 and a blood pump 4 are driven, blood is taken out from a blood donor. When the taken-out blood reaches a blood removing amount expelling the priming liquid in a membrane module 3, the control apparatus 40 receives the detection signal of the first detector 5 to drive a plasma pump 8. The blood corpuscle separated by the membrane module is stored in a bag 6 and the plasma component is stored in a bag 7. When the control apparatus receives the detection signal from the first detector 5 and the blood removing amount reaches a predetermined amount, the blood pump 4 is reversely driven to enter a blood return process. As mentioned above, when the cycle of the blood removing process and the blood return process is repeated, the effect of dilution due to the priming liquid is avoided and good quality plasma high in protein concn. can be collected.
