Abstract

A capillary dialyzer comprises: a) a housing; a bundle of semi-permeable hollow fiber membranes; c) end walls supporting the first and second ends of the hollow fiber membranes; d) a first end cap covering a first end of the housing and a second end cap covering a second end of the housing; e) an inlet and an outlet; f) support rings; and g) sealing rings interposed between the end wall and the first end cap and between the end wall and the second end cap, respectively. A circular groove of the end cap which receives the wall of the housing comprises indentations for creating a fluid connection between the inside of the capillary dialyzer and its exterior when the end caps are mounted on the housing but have not yet been welded to the housing.
