Abstract
A biological component treatment cassette (blood component collection cassette (28)) is configured to be attachable to a separation device (centrifugal separation device (14)) adapted to separate a biological component from a liquid containing at least one biological component, and a flow path (42) is formed in an interior portion thereof. The biological component treatment cassette includes a sheet-shaped cassette main body (40), and a first pump action tube (58), both ends of which are connected to the flow path (42) of the cassette main body (40), together with a portion thereof protruding from an outer peripheral edge portion of the cassette main body (40), and which is made from a soft material that is pressed by a pump (80) of a separation device.

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, and having a flow path formed in an interior portion thereof, the biological component treatment cassette comprising:
- a cassette main body formed from a flexible upper sheet and a flexible lower sheet between which there is formed a flow path wall configured to form the flow path in an interior portion thereof, said cassette main body having a flexible peripheral edge portion;
- and
- a pump action tube, both ends of which are connected to the flow path of the cassette main body, together with a portion thereof protruding from said outer peripheral edge portion of the cassette main body, and which is made from a soft material that is pressed by a pump installed in the separation device in order to cause a fluid to flow inside the flow path.
A biological component treatment system equipped with
- a separation device adapted to separate a biological component from a liquid containing at least one biological component, and
- a biological component treatment cassette configured to be attachable to the separation device, and having a flow path formed in an interior portion thereof;
- wherein the biological component treatment cassette comprises:
- a cassette main body formed from a flexible upper sheet and a flexible lower sheet between which there is formed a flow path wall configured to form the flow path in an interior portion thereof, said cassette main body having a flexible peripheral edge;
- and
- a pump action tube, both ends of which are connected to the flow path of the cassette main body, together with a portion thereof protruding from an outer peripheral edge portion of the cassette main body, and which is made from a soft material;
- and
- the separation device comprises a pump configured to press on the pump action tube in order to cause a fluid to flow inside the flow path.
