Title
(EN) A DEVICE FOR THE DIFFUSION OF SUBSTANCES BETWEEN TWO FLUIDS VIA SEMIPERMEABLE MEMBRANES
(FR) DISPOSITIF DE DIFFUSION DE SUBSTANCES ENTRE DEUX FLUIDES VIA DES MEMBRANES SEMI-PERMEABLES
Abstract
(EN)
A device for the diffusion of substances between two fluids via semipermeable membranes (2), which are arranged in a stack separated by spacer plates (1), which on their surfaces are provided with ducts (18, 35) connected to the inlets and outlets (4-7) for at least one of the said fluids, these spacer plates (1) being arranged in the folds of one or more membranes (2) folded in zigzag. The device is characterized by two transverse ducts (18) arranged near two opposite front edges (17) of the plates (1) substantially parallel with these front edges (17), which open onto at least one of the lateral edges (24), which connect the front edges (17) of the plates (1). The device is intended to be used as a so-called artificial kidney, where the said fluids consist of blood and of dialysis liquid respectively.
(FR)
Dispositif de diffusion de substances entre deux fluides via des membranes semi-permeables (2), qui sont empilees et separees par des plaques d"espacement (1) qui sont pourvues sur leur surface de tubes (18, 35) connecte aux entrees et aux sorties (4-7) pour au moins l"un des deux fluides, ces plaques d"espacement (1) etant disposees dans les replis d"une ou de plusieurs membranes (2) pliees en zigzag. Le dispositif est caracterise par deux tubes transversaux (18) disposes a proximite de deux bords avant opposes (17) des plaques (1) sensiblement paralleles a ces bords avant (17), qui debouchent sur au moins l"un des bords lateraux (24), qui relient les bords avant (17) des plaques (1). Le dispositif est destine a etre utilise comme un rein artificiel dans lequel les fluides sont d"une part du sang, et d"autre part un liquide de dialyse, respectivement.
