  • Method and apparatus for plasma treatment
    Patent number: 4747952
    Abstract: Separation apparatus capable of separating plasma into high molecular weight substances and low molecular weight substances containing albumin, regardless of whether plasma is obtained by separation of corpuscular components in a continuous centrifugal separator or in a batch-type centrifugal separator. The apparatus comprises a filtration membrane module, a plasma feeding circuit connecting the centrifugal separator with the filtration membrane module, a plasma return circuit for returning to a patient purified plasma freed of high molecular weight substances, a supplemental fluid circuit for supplying additional fluid to the plasma return circuit, and a condensed plasma discharge circuit for disposal of high molecular weight substances. The apparatus is controlled independently of the centrifugal separator.
