Abstract
A biological component treatment cassette (blood component collection cassette (28)) is configured to be attachable to a separation device (centrifugal separation device (14)), and a flow path (42) is formed in an interior portion thereof. The biological component treatment cassette includes a wall portion forming a part of the flow path (42, and is equipped with pump action members (first and second pump action members (58, 66)) formed of a soft material and which are pressed by pumps of the separation device. The pump action members include pump pressed portions (first pump pressed portions (58a), second pump pressed portions (66a)).
Claims9
A biological component treatment cassette configured to be attachable to a separation device adapted to separate a biological component from a liquid containing at least one biological component wherein the separation device includes a pump on which a plurality of pressing members are arranged substantially in a straight line,
- the biological component treatment cassette comprised of a soft, flexible material, and has a wall portion forming a flow path in an interior portion of said cassette;
- and
- on a part of the wall portion, there is a pump pressed portion which is adapted to be pressed by the plurality of pressing members of the pump in order to cause the liquid to flow inside the flow path.
