Method and device for separating whole blood into an erythrocyte concentrate and cell-free or thrombocyte-containing plasma under gravitational force

摘要

The invention relates to a method for separating whole blood into a leukocyte-depleted erythrocyte concentrate and plasma. According to said method, whole blood is separated into an erythrocyte concentrate and plasma in a first step in a plasma filter, and is then separated into a second erythrocyte concentrate and more plasma during the return flow through the same plasma filter. The erythrocyte concentrate obtained is mixed with an additive solution. The entire separation system per se is closed and sterile.
