Abstract
A blood component separation device for separating a plurality of blood components from blood sampled from a blood donor, and collecting platelets, includes: an donor calculation unit that calculates a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood, and calculates a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate, wherein the operating unit sets the predicted platelet recovery rate calculated from any the hematocrit value and any the platelet concentration to be smaller by a predetermined value α when the blood donor is female than that when the blood donor is male.
Claims6
A method for collecting platelets with a blood component separation device for separating a plurality of blood components from blood sampled from a blood donor comprising:
- calculating a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood;
- calculating a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate;
- and
- setting the predicted platelet recovery rate calculated from the hematocrit value and the platelet concentration to be smaller by a predetermined value when the blood donor is female than that when the blood donor is male, thereby increasing a number of collection cycles for a female donor as compared to a male donor having the same platelet concentration.
