Abstract
A blood reservoir (20) for storing blood includes a first storage section (21), a second storage section (22), and a third storage section (23) that is provided between the first storage section and the second storage section, and communicates with the first storage section and the second storage section. A volume of the blood reservoir (20) can be adjusted by changing the amount of expansion or contraction of a bellows structure (28) using a bellows adjustment mechanism (83, 93).
Claims22
A blood component separation device, comprising:
- a blood reservoir configured to store blood and used for centrifugation of blood stored in the blood reservoir, wherein the blood reservoir comprises:
- a first storage section, a second storage section, and a third storage section that is provided between the first storage section and the second storage section, and communicates with the first storage section and the second storage section,
- a support member configured to prevent deformation of the third storage section during centrifugation;
- a bottom cap that is in contact with at least a part of a bottom of the first storage section, wherein one of the support member and the bottom cap has a male thread and the other of the support member and the bottom cap has a female thread;
- a bellows structure provided on the blood reservoir, configured to be expandable and contractable;
- and
- a bellows adjustment mechanism comprising the male thread and the female thread, and configured to adjust an amount of expansion or contraction of the bellows structure based on a depth of screwing the male thread into the female thread, which adjusts the amount of expansion or contraction of the bellows structure,
- wherein a volume of the blood reservoir is adjusted by adjusting the bellows structure using the bellows adjustment mechanism.
