This blood component separation device has: a centrifuge bowl for separating blood components in blood; a plasma bag for storing plasma components; a platelet middle bag for storing a high-concentration platelet liquid having a high concentration of platelets; and a temporary storage bag, which doubles as a buffy coat bag, for storing a low-concentration platelet liquid having a low concentration of platelets. In this blood component separation device, which, from a second cycle onward, performs control in such a manner as to mix the low-concentration platelet liquid stored in the temporary storage bag with whole blood and feeds said mixture to the centrifuge bowl in the immediately preceding cycle: the amount of the high-concentration platelet liquid collected in the first cycle in which the platelet liquid is collected in the platelet middle bag is compared with the amounts collected in the other cycles, and the amount is set to the lowest value; and the amount of the high-concentration platelet liquid collected in the last cycle is compared with the amounts collected in the other cycles, and the amount is set to the highest value.
Description
technical field [0001] The present invention relates to a blood component separation device for collecting platelets from blood. More specifically, it relates to a blood component separation device for concentrating and collecting platelets. Background technique [0002] Conventionally, component blood collection in which only platelets and the like are collected and other components are returned to the blood donor has been mainly performed in blood collection. In this case, a blood component separator having a centrifugal separator is used. [0003] In recent years, blood transfusion of platelet fluid has been widely performed in radiotherapy for cancer, etc., and in this case, high-concentration platelet fluid is required. In order to collect high-concentration platelet fluid, the technique of Patent Document 1 is carried out as follows: In the blood component separation device, low-concentration platelet fluid is temporarily stored in a buffy coat bag, and only high-conc...
