CENTRIFUGE DRUM FOR PLASMAPHERESIS Russian patent published in 2022 - IPC A61M1/36 A61M1/34 

FIELD: medical equipment.

SUBSTANCE: core of the drum for plasmapheresis comprises a cylindrical body forming the core and the inner part of the core. A protrusion is located in the inner part of the core between the proximal end and the distal end of the cylindrical body. The protrusion extends radially inward from the inner diameter of the core and has an upper surface forming, at least partially, a collection chamber inside the drum for plasmapheresis. Ribs are located on the proximal section of the cylindrical body and spaced around the proximal section of the cylindrical body. The ribs extend over the proximal end of the cylindrical body, thereby creating flow paths between each of the ribs, wherein the flow paths allow for entrance of the fluid medium into the inner part of the cylindrical body and the collection chamber. Disclosed are a supply tube for the centrifuge drum for plasmapheresis and a drum for plasmapheresis.

EFFECT: increase in the effectiveness of separation of cellular elements and reduction in the foam formation.
