Abstract
A blood bag system includes a BC pooling bag for centrifugation of a buffy coat, a filter for removing white blood cells from a supernatant liquid transferred from the BC pooling bag, a platelet preserving bag for reserving the supernatant liquid that has passed through the filter, a first tube connecting the BC pooling bag and an inlet of the filter, a second tube connecting the platelet preserving bag and an outlet of the filter, and a cassette to be fixed in the centrifugation and separation apparatus. The first tube and the second tube are disposed within the cassette. The cassette includes a first clamp section for closing and opening the first tube, and a second clamp section for closing and opening the second tube.

A blood bag system comprising:
- a first bag for reserving whole blood or a blood component;
- a filter having a filter medium for removing predetermined cells from a blood component obtained by centrifugation of the liquid contained in the first bag;
- a second bag for reserving a blood component obtained upon removal of the predetermined cells by the filter;
- a first tube for connecting the first bag and an inlet of the filter;
- a second tube for connecting the second bag and an outlet of the filter;
- and
- a cassette for holding a part of the first tube and a part of the second tube,
- wherein the cassette has a first clamp section for closing and opening the first tube and a second clamp section for closing and opening the second tube.
