ABSTRACT "Dialyser comprising hollow fibre membranes" A dialyser which comprises bundled multicomponent hollow filaments as membranes which, on the dialysate side, comprise a layer containing adsorbent particles and, on the retentate side, comprise a layer of regenerated cellulose and, optionally, at least one cellulose derivative and which, at the ends thereof, are embedded in hardened polyurethane and are cut through to form a tube base which uncovers the openings of the hollow filaments, the cut surfaces being sealed with at least one polyurethane which ranges from 0.2 to 2 um in thickness and which leaves the openings of the filaments free is disclosed. The present invention obviates the problems caused by the adsorbent particles being torn from the embedding composition.
