A connector for medical tubing for liquid transfusion includes a short tubular male connector member made of thermally resistant corrosionproof materia; a short tubular female connector member made of thermally resistant corrosionproof material; and a fitting surface portion on the outer surface of an insertion end of the male connector, shaped in the male form and made of a material having a smaller thermal expansion coefficient than the material of a corresponding fitting surface portion on the inner surface of an insertion end of the female connector shaped in the female form. The fitting surface portion of the insertion end shaped in the male form, and the fitting surface portion of the insertion end shaped in the female form, are of relative sizes such as to permit the insertion ends to be connected to and separated from each other by shrink fit utilizing the difference between the thermal expansion coefficients thereof. A medical solution bag device using the connector is also disclosed.

A body fluid-filtering device includes a housing provided with a body fluid inlet, a filtrate outlet and a filtration residue outlet, and a filtering means disposed in the housing and including first and second filtering elements alternately superposed on each other with a space therebetween. The first and second filtering elements are each formed of a meshed core material and filtering membranes which cover both sides of the core. The core material of the first filtering element has openings of 700 to 1300 microns, and the core material of the second filtering element has openings of 300 microns or less.

A dialyzer comprises a housing, a plurality of hollow fibers extending in the housing parallel to one another, solution inlet and outlet ports provided at the ends of the housing through respective seal members, respectively and communicating with liquid passages inside the hollow fibers, and dialysate inlet and outlet ports provided near the ends of the housing, respectively, and communicating with a liquid passage outside the hollow fibers. The dialysate inlet port has a diameter of 1.5 to 3.5 mm, and the dialysate outlet port has a diameter of 6 to 10 mm.
