SYSTEMS AND METHODS FOR OPTIMIZING PLASMA INTAKE VOLUMES Russian patent published in 2021 - IPC A61M1/38 

FIELD: medical technology.

SUBSTANCE: invention relates to medical technology, namely to systems for plasmapheresis and methods for controlling the system for plasmapheresis, by which the volume/weight of the anticoagulated plasma that is taken is optimized. In one example, a nomogram is proposed that uses the donor's hematocrit to calculate the volume/weight of untreated plasma in a plasma product having the maximum volume allowed by the FDA nomogram. In a plasmapheresis procedure involving multiple sampling phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated before the start of each sampling cycle to account for the increase in the donor's hematocrit, resulting in a larger total volume of plasma product to be collected during the plasmapheresis procedure.

EFFECT: controlling the system for plasmapheresis, by which the volume/weight of the anticoagulated plasma that is taken is optimized.
