BLOOD BAG SYSTEM AND CASSETTE

摘要

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.

1. 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 connecting the first bag and an inlet of the filter; a second tube connecting the second bag and an outlet of the filter; a cassette comprising a first guide passage holding a part of the first tube and a second guide passage holding a part of the second tube; wherein the cassette has a first clamp section which is integrally molded with the cassette and is movable relative to the first guide passage and toward the part of the first tube held in the first guide passage to close the first tube and movable relative to the first guide passage away from the part of the first tube held in the first guide passage to open the first tube, the cassette also having a second clamp section which is integrally molded with the cassette and is movable relative to the second guide passage and toward the part of the second tube held in the second guide passage to close the second tube and movable relative to the second guide passage away from the part of the second tube held in the second guide passage to open the second tube, the first clamp section being different from the first and second guide passages, and the second clamp section being different from the first and second guide passages; and wherein the first clamp section and the second clamp section are in a common plane.
