Abstract
PURPOSE: To obtain a concentrated solution of platelet, by putting a porous filter membrane between the first chamber having an introduction path for polyplatelet plasma and the second chamber having an discharge path for nonplatelet plasma, followed by concentrating the polyplatelet plasma.
CONSTITUTION: The blood is fed to the centrifugal separator 13, and centrifugal force is applied to it to give polyplatelet plasma as a supernatant liquid. The fixed delivery pump 7 is operated, the polyplatelet plasma is introduced from the introduction path 2 to the first chamber 3, nonplatelet plasma is filtered by the porous filter membrane 1 (preferably the maximum pore diameter of ≤2μ, especially 0.1W 0.5μ), the nonplatelet plasma is discharged from the second chamber 5 and discharging path 4, and the polyplatelet plasma is concentrated by the first chamber 3. When the concentration is insufficient, the fixed delivery pump 10 is operated and it is joined with unconcentrated polyplatelet plasma and concentration is carried out again. Erythrocyte and leucocyte as a sedimentation component in the centrifugal separator 13 are returned from the blook tube 14 to the outside, and the concentrated polyplatelet plasma is discharged by operating the fixed delivery pump 8, thus to make continuous treatment possible.
