Abstract
An apparatus is provided for reacting a solution of a precipitating medium of alkaline metal chlorides at a fixed rate of delivery with plasma continuously separated from blood, filtering the precipitate formed by the reaction, removing the solution of precipitating medium from the plasma following the use of the medium, adjusting the purified treated plasma, and returning the purified plasma to the blood in an amount equivalent to that of the continuously separated plasma. To enhance the precipitative separating action of alkaline metal chloride on plasma protein without detracting from the advantages of the alkaline metal chloride, use is made of a solution of precipitating medium comprising a mixture of the alkaline metal chloride and an amino acid, the latter being added in an amount sufficient to promote the precipitating effect of the alkaline metal chloride.
