An apparatus is described for effecting mass and/or heat transfer, including a cylindrical open-ended housing (1) closed by two end caps (4) , each provided with an inlet (5) or an outlet (6) for a first fluid intended to flow through a bundle of hollow fibers (2) arranged within the housing (1) between two end walls (3) , at least one of said end caps being provided with an outlet (8) for a second fluid intended to be removed from the space outside the fibers (2), the inlets and/or outlets (5-8) provided in one and the same end cap being separated by the adjacent end wall (3). The apparatus described is characterized by a ring (15) arranged in the housing (1) and/or the end cap in such a way that a channel or channels (17) is/are provided, connecting said outlet (8) for the second fluid with the space outside the fibers (2). Preferably the apparatus according to the invention is intended for hemofiltration, hemodiafiltration or hemodialysis. It may, however, also be used for dialysis in general or filtration in general and for heat transfer or as an oxygenator. <IMAGE> |
