摘要:
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), ayant des trous de passage (13, 23) en connexion avec les entrees et les sorties respectives des fluides, un premier fluide pouvant etre conduit d'un cote des membranes respectives et un second fluide pouvant etre amene du cote oppose des memes membranes. De preference, les membranes (2) sont disposees par paires entre les plaques d'espacement (1). L'entree et/ou la sortie (8) pour l'un des deux fluides au moins, est connectee d'un cote d'un tube (2) intersectant la pile et forme par les trous de passage (13). Le dispositif est destine essentiellement a etre utilise comme un rein artificiel, les deux fluides etant d'une part du sang et d'autre part un liquide de dialyse, respectivement.
摘要:
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 characterised 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.

摘要:
Semipermeable membranes (2) are arranged in a stack separated by supporting plates (1) having a first plane face and a second plane face (10,12) and comprising through-openings (7,8) connected to an inlet and outlet, respectively, for a first fluid, by means of which this first fluid is conducted to the one side of the respective membrane, whilst a second fluid is conducted ot the other side of the membrane, the stack of membranes and supporting plates having an elongated shape with a flow-through duct formed of the said through-openings (7,8) arranged straight through the stack near its two ends. The invention is characterized by channels (11,11′) originating from end edges (9,9′) of the supporting plates, open towards a frist plane face (10,12), for the conducting of the said second fluid past a seal (13,13a′) arranged on the opposite plane face (12,10) to an opening (14,14′) passing through the plate for the conducting of this second fluid to, respectively from, the space inside the said seal (13,13a′) on the said opposite plane face (12,10) of the plate. The arrangement in accordance with the invention is intended in particular to be used in connection with dialysis, haemofiltration and similar extracorporeal procedures for the treatment of blood.
摘要:
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 comprise through-holes (13, 23) connected to inlets and outlets respectively for the respective fluids, a first fluid of which is arranged so as to be conducted on one side of the respective membranes and a second fluid on the opposite side of the same membranes. Preferably the membranes (2) are arranged in pairs between the spacer plates (1). The inlet and/or the outlet (18), for at least one of the said fluids, is connected from the side to a duct (12) intersecting the stack and formed by the said through-holes (13). The device is intended and foremost to be used as a so-called artificial kidney, the said fluids consisting of blood and dialysis liquid respectively.

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.
