The needle 14 is punctured into the arm of the focal plane WD, the first clamp 9 a , the third clamp 9 CN, and the fifth clamp 9 e are opened, and the remaining clamps are made into locks. When the first to third pumps 8a to 8c are driven in this state,
Blood is drawn from the donor's arm via needle 14. This blood flows through the blood circuit while being mixed with ACD fluid. In addition, this blood causes physiological saline and the like in the blood circuit to be expelled via the second chamber 11b1, the inner chamber 13b of the separator 13, and the blood detector 12a, and is finally discharged into the drainage bag 6.
