摘要： A dialyzer provided in a cylindrical housing with a bundle of hollow fiber membranes and first flow paths and second flow paths separated from each other by said hollow fiber membranes and allowed to effect dialysis and ultrafiltration through the medium of said hollow fiber membranes between a body liquid flowing through said first flow paths and a dialyzing liquid flowing through said second flow paths, characterized in that a constricted part is formed halfway in the length of said second flow paths with a material capable of being swelled by said dialyzing liquid so as to confer a difference of pressure on said dialyzing liquid on the upstream side and the downstream side of said dialyzing liquid relative to said constricted part.

摘要： The present invention provides a forming method capable of inexpensively forming a bodily fluid purification cassette which is reduced in size as small as possible. A bodily fluid purification cassette is detachably attached to a bodily fluid purification apparatus body. The bodily fluid purification cassette includes a synthetic resin box-like body; a basic element incorporated in the box-like body; a selective element selected from a bodily fluid purification element such as a dialyzer, a plasma exchange module and an immunoadsorbent cylinder; and bodily fluid flow passages which connects the basic element and the selective element with each other. The box-like body and the bodily fluid flow passages are formed by primary molding such that a cross section of a split-type structure has a predetermined shape, and the split-type structure is integrally formed into a cassette by secondary molding. When the bodily fluid flow passages of the split-type structure are integrally formed by secondary molding, the basic element and the selective element are liquid-tightly connected to the bodily fluid flow passages.
