SISTEMA DI SCOAGULAZIONE REGIONALE PER UN CIRCUITO DI CIRCOLAZIONE EXTRACORPOREA DEL SANGUE

A system (I, 100,200) is described for the regional decoagulation of the bio od in an extracorporeal circulation circuit comprising means (7, 8, 9) for infusion of a solution of a citrate or citric acid on the main circuit (6), which are set upstream of the first filtration unit (4); means (19, 20, 21) for infusion of a solution for electrolyte restoration on the main circuit (6), which are set downstream ofthe filtration unit (4) and a secondary circuit (lO) for recirculation of the plasma water obtained by the filtration unit (4). The secondary circuit (lO) comprises: a first cartridge (13) comprising an anion-exchange resin charged with chIorine ions; a second cartridge (14) comprising a cation-exchange resin charged with sodium and potassium ions, which is set downstream ofthe first cartridge (13) and means (17, 18) for removal of a first fraction (30.3) of the plasma water (30) obtained by the filtration unit (4).
