Abstract
Spacers for membrane exchanges whose useful exchange zone is divided by at least one transversal rib directing one of the fluids to the side of the exchange zone where it passes through orifices to circulate subsequently on the opposite face. Application to heat and/or material exchanges with various fluids, especially biological fluids. Particular applications in haemodialysis and in blood oxygenation.
Claims24
A spacer for a device for exchanging heat and/or material between fluids through at least one membrane supported by the said spacer, the spacer comprising a solid plate having a pair of opposed, major faces, on each face of which is defined an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends are connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flowing between the face of the said spacer and the adjacent membrane into a least one longitudinal cavity aligned within the longitudinal edge of the spacer.
A device for exchanging heat and/or material between fluids, the device comprising at least one exchange membrane through and at least one spacer supporting same, the spacer comprising a solid plate having a pair of opposed, major faces, on each face an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flowing between the face of the said spacer and the adjacent membrane into at least one longitudinal cavity aligned within the longitudinal edge of the spacer.
A spacer for haemodialyser and/or blood oxygenator comprising a solid plate having a pair of opposed, major faces, on each face of which is defined an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends are connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flowing between the face of the said spacer and the adjacent membrane into at least one longitudinal cavity aligned within the longitudinal edge of the spacer.
A spacer for a device for exchanging heat and/or material between fluids through at least one membrane supported by the said spacer, the spacer comprising a solid plate having a pair of opposed, major faces, on each face of which is defined an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends are connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flowing between the face of the said spacer and the adjacent membrane, wherein in the said exchange zone there is associated with the at least one rib means defining at least one orifice provided through the thickness of the spacer, permitting a fluid to flow from one face of the spacer to the opposite face.
A device for exchange heat and/or material between fluids, the device comprising at least one exchange membrane through and at least one spacer supporting same, the spacer comprising a solid plate having a pair of opposed, major faces, on each face an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends are connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flow between the face of the said spacer and the adjacent membrane, wherein in the said exchange zone there is associated with the at least one rib means defining at least one orifice provided through the thickness of the spacer, permitting a fluid to flow from one face of the spacer to the opposite face.
A spacer for haemodialyzer and/or blood oxygenator comprising a solid plate having a pair of opposed, major faces, on each face of which is defined an exchange zone extending longitudinally between a distribution zone and a collection zone for one of the fluids, means for ensuring peripheral leaktightness, the said exchange zone being divided on at least one of the faces of the said solid plate into separate compartments by at least one continuous transversal rib whose two ends are connected to the said means for ensuring peripheral leaktightness, the said rib forming a leaktight baffle which channels and directs on one side the fluid flowing between the face of the said spacer and the adjacent membrane, wherein in the said exchange zone there is associated with the at least one rib means defining at least one orifice provided through the thickness of the spacer, permitting a fluid to flow from one face of the spacer to the opposite face.
