Abstract
The present invention relates to a machine for performing purification of whole blood that circulates in a flow duct on which there is a stage for filtering plasma from whole blood, which can be functionally arranged in connection to a plasma purification circuit; a stage for dialysis of the whole blood by means of plasma purified in the circuit being provided on the flow duct; the stage comprising a selectively permeable interface for separating part of the whole blood stream of the duct from a countercurrent stream of plasma purified in the purification circuit.

A blood purification device, comprising a duct for the flow of whole blood along which there is a stage for filtering plasma from the whole blood, which is functionally arrangeable in connection to a plasma purification circuit, and a stage for whole blood dialysis by means of plasma purified in said circuit, said stage for whole blood dialysis comprising a selectively permeable interface for separating at least part of the whole blood stream of said duct from a countercurrent stream of plasma purified in said circuit.
A blood purification method comprising the steps of:
- filtering plasma from whole blood,
- purifying said plasma filtered from whole blood,
- purifying said whole blood by flow in countercurrent of a stream of said purified plasma, separated from the stream of said whole blood by a permeable interface.
