PURPOSE: To reduce a size and weight and to improve operability by collectively disposing operating sections and display sections atop the device.

CONSTITUTION: The setting and display device 1 for various kinds of pressures, such as TMP, return blood pressure, filter pressure, and module inlet pressure, the alarm condition display device 2 for bubbles, heparin run-out, pressure, etc., the flow rate setting section 3a for a blood pump, the blood pump flow rate setting section 3b, the filter pump flow rate setting section 4a, the filter pump flow rate display section 4b, the integrated filtrate volume display section 5, the heparin pump flow rate setting section 6a, and the haparin pump flow rate display section 6b, are respectively concentrically disposed atop the blood cleaning device. The pumps are disposed on the front surface and the detecting sensors for pressures and bubbles and means for opening and closing flow passages are disposed on the flanks. The easy operation of an ICU, CCU, etc., even in a narrow pace is assured by this constitution.
