ABSTRACT:
A method for separating blood into blood components aseptically in a closed system first filters whole blood through a filter for removing leukocytes or removing leukocytes and platelets, to produce filtered blood, which is passed to and collected in a primary bag fluid-tightly connected to the filter through a sealable, cuttable conduit, and the conduit is sealed and cut to disconnect the primary bag from the filter. The disconnected primary bag is subjected to centrifugation to separate the filtered blood into blood components. The method is useful for separately collecting leukocyte-removed blood components, particularly leukocyte-removed erythrocytes, leukocyte-removed plasma, leukocyte-removed platelets, etc., from the whole blood of a healthy human. A blood components separation unit which can advantageously be used in the practice of the above method is also disclosed.
