[Claim for Utility Model Registration] Blood is introduced into the plasma separator 3 from the blood introduction part H1 , separated into blood cell components and plasma components, and the separated blood cell components are delivered to the human body from the blood delivery part H2 . A blood circulation flow path 1 for returning blood, a plasma flow path 2 for discharging plasma components separated by the plasma separator 3, and a blood circulation flow path 1 downstream of the separator 3 for discharging replacement fluid in an amount equal to the plasma components. a replacement fluid flow path 6 that returns to the human body via the
A drain pump 7 provided in the plasma flow path 2 and the replacement fluid flow path 6; A pressure detector 23 provided in the blood circulation flow path 1 at least on the inlet side or outlet side of the plasma separator 3.
, or 26, a pump driving means 13 that drives the blood pump 4 and the drain pump 7 at normal speed so as to maintain a predetermined flow rate ratio, and is activated in response to an abnormal pressure detection signal from the pressure detector 23 or 26. and low-speed drive means 14 for driving the blood pump 4 and drain pump 7 at a low speed lower than normal speed and at the predetermined flow rate ratio.
