METHODS AND MACHINE BASED ON BLOOD SEPARATION BY FILTRATION FOR PLASMA EXCHANGE TREATMENT, PLASMA DONATION AND CYTAPHERESIS SUCH AS PLATELET APHERESIS

摘要

Machine for plasma exchange treatment, plasma donation and apheresis as apheresis platelets, having control means (24) for adding a liquid to the blood flow through a branch (25) between a pump (10) and a reservoir (15) for blood cells, associated with separating means (14) for separating the filtered blood into various components. The invention also relates to a method for operating such a machine, and a method for such as apheresis apheresis platelets, wherein said liquid is mixed with the blood being sampled on a donor / patient and / or current to return to donor / patient after the separation process.
