Abstract: PROBLEM TO BE SOLVED: To improve a blood remaining characteristic by passing a model blood which exhibits the behavior similar to the behavior of the human total blood of a specific temperature in a relation between a viscosity and a shear rate in a specific amount in such a manner that the residual amount of the model blood at the time of washing with a specified amount of a phosphoric acid buffer solution of a specific pH and specific formulation attains a specific value or below. SOLUTION: The model blood which exhibits the behavior similar to the behavior of the human total blood of 37 deg.C in the relation between the viscosity and the shear rate is introduced into the hollow fiber type blood purifying device at a flow rate of 1.28 times the volume of the flow passage of this device. The hollow fiber membranes are then washed by passing the phosphoric acid buffer solution of pH 7.5 at 125 ml/m2 per unit inside surface area of the hollow fiber membranes and at a flow rate of 100 ml/min. The human total blood is hematocrit(ht) 40%.total protein(TP) 8. The phosphoric acid buffer solution is 5.33 mmol disodium hydrogenphoshate dodecahydrate, 1.34 mmol potassium dihydrogenphoshate and 154 mmol sodium chloride. The remaining of the blood after washing is confined to

Abstract: PROBLEM TO BE SOLVED: To improve blood treatment efficiency and to prevent the remaining of the blood by confining the inclination of the inside wall of a blood introducing port or blood leading-out port of a blood port with respect to the central axis of the blood port to a specific value or below. SOLUTION: The inclination θ of the inside wall of the blood introducing port or blood leading-out port of the blood port with respect to the central axis of the blood port is set at =0.5 deg., the mold parting in injection molding is facilitated and such value is preferable. The inclination θmay widen or narrow the flow passage in the progression direction of blood flow. The relation 0.08D
