Abstract

A method for venting a dialyzer which has a dialyzate chamber, a blood chamber and a semi-permeable dialyzer membrane separating these two chambers. An overpressure is generated in the dialyzate chamber with respect to the blood chamber for removing air inclusions lying at the surface of the membrane at the dialyzate chamber side after a filling of the dialyzate chamber and before a filling of the blood chamber.
