| 1. A method for assembling a blood treatment circuit by aseptically connecting a connected bag set, which has previously been
sterilized, and a filter unit, which has previously been sterilized, to each other, said connected bag set being composed
of a primary bag holding collected blood and a plurality of secondary bags holding blood or blood components and a first tube
to connect said primary bag to said secondary bags and a third tube to connect said secondary bags to one another, said filter
unit having an inlet and an outlet, a filter medium to remove specific components from a fluid introduced through said inlet,
and a second tube, both ends of which are connected to said inlet and said outlet, and to which a bag is not connected, wherein
said method comprises:
cutting either said first tube or said third tube so that either said first tube or said third tube comprises first and second
cut ends;
cutting said second tube so that the second tube comprises first and second cut ends;
aseptically connecting said first cut end of said first tube or said third tube to said first cut end of said second tube,
and connecting said second cut end of said first tube or said third tube to said second cut end of said second tube, thereby
placing said filter unit along said first tube or said third tube.
