ABSTRACT:
A device for exchange between fluids, shown especially adapted for exchange between blood and a treatment fluid. The device comprises a first set of fluid channels for blood and a second set of channels for a treatment fluid. Each channel of the first set is defined by a pair of panels of semi-permeable membrane which are supported along spaced-apart lines by supports. At least a portion of the channels of the second set are defined by a pair of membrane panels and a pair of the supports. Each set of channels is arranged into a plurality of layers, the layers alternating between channels of the first and second sets. The resulting three dimensional array of blood and treatment fluid paths enables strict channeling to ensure equal exposure and flow of all blood and treatment fluid while simultaneously achieving double exposure of the treatment fluid as it flows between layers of blood.
