Publication number: 20160317727Abstract: In order to prevent or suppress a blood component from being unnecessarily mixed to other bags by returning blood moved to a tube from a bag before centrifuge to the bag during the centrifuge. A blood bag system (10) has a cassette (50) (tube holder) for holding at least a part of the first transfer tube (21). The cassette (50) holds the first transfer tube (21) such that a distance between a rotation center (O) in application of a centrifugal force and the first transfer tube (21) increases toward the blood collection bag (11) side across a length between a flow path close position caused by the first clamp (71) in the first transfer tube (21) and the blood collection bag (11).Type: ApplicationFiled: November 19, 2014Publication date: November 3, 2016Applicants: Terumo BCT, Inc., Terumo Kabushiki KaishaInventors: Makoto HIRABUKI, Tadashi IMAI
