Abstract
An apparatus for hemo(dia)filtration comprises an extracorporeal blood circuit and a supply line of a replacement fluid to the extracorporeal blood circuit. The supply line has a bifurcation which divides a main branch (24) into a pre-dilution branch (25) and a post-dilution branch (26). A pump tube tract (29) is predisposed in the supply line for coupling with a circuit pump of the replacement fluid. An expansion chamber is predisposed in the extracorporeal blood circuit and is fluidly connected to the pre-dilution branch. The invention provides a disposable fluid circuit usable for performing a hemodiafiltration treatment with pre-dilution and post-dilution which is couplable simply, rapidly, economically and reliably to a machine for monitoring the treatment.

25. An hemo(dia)filtration apparatus comprising:
-
an extracorporeal blood circuit having an arterial line and a venous line; a supply line of replacement fluid for the extracorporeal blood circuit, said supply line having a bifurcation which divides a main branch into a pre-dilution branch fluidly connected to the arterial line and a post-dilution branch fluidly connected to the venous line; a pump tube tract predisposed in said supply line for coupling with a pump for circulation of the replacement fluid, said pump tube tract being conformed as an open ring with an aspiration end and a delivery end; and an expansion chamber predisposed in said extracorporeal blood circuit;
one of said pre-dilution branch and said post-dilution branch leading to said expansion chamber;
said aspiration end and said delivery end being rigidly connected to said expansion chamber. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
