Abstract
A hemodiafiltration system for treating blood which has module having a housing in which hollow-fiber membranes are arranged in the direction of the longitudinal extent and are embedded at their ends in first and second sealing compounds joined to the inner wall of the housing in a fluid-tight manner. The membrane module also has a dialyzate space and a substituate space separated from the dialyzate space in a fluid-tight manner by a continuous dividing wall. The membrane module further includes means for delivering and withdrawing a dialyzate to and from the dialyzate space, and means for delivering a substituate to the substituate space. The hollow-fiber membranes are used for blood treatment, filtration of the substituate, and delivery of the substituate to the blood. An exterior space is formed around the hollow-fiber membranes that is delimited by the inner wall of the housing and sealing compounds and is divided along the longitudinal extent of the housing by a dividing wall into the substituate space and the dialyzate space, the dividing wall encloses each individual hollow-fiber membrane.
