BLOOD COMPONENT SEPARATION DEVICE

摘要

A blood reservoir (20) for storing blood comprises a first reservoir part (21), a second reservoir part (22), and a third reservoir part (23) which is provided between the first reservoir part and the second reservoir part and is in communication with the first reservoir part and the second reservoir part. The blood reservoir (20) is provided with a bellows structure (28). The volume of the blood reservoir (20) can be adjusted by changing the amount of distraction or compaction of the bellows structure (28) with bellows adjustment mechanisms (83, 93).
