Problems solved by technology

Therefore, the recovered solution (physiological solution) is included in the prepared PPP, and there is a problem that the concentration of PPP decreases.
In addition, in the prepared CRC and PC, since the effect of preventing the function reduction of red blood cells or platelets in the physiological solution is poor, there is a possibility that a blood component preservation solution (erythrocyte preservation solution or platelet preservation solution) has to be newly added. question

Abstract

The blood bag system (30) has a blood processing filter (8) for processing blood, a first bag (1) for holding the blood to be supplied to the blood processing filter (8), a second bag (2) for holding the blood processed by the blood processing filter (8), a preservative solution supply means (7) for supplying a blood element preservative solution to the blood processing filter (8), a third bag (3) that recovers blood remaining in the blood processing filter (8) that is displaced by the blood element preservative solution and stores the recovered blood temporarily, and a fourth bag (4) to which blood elements separated from the processed blood held in the second bag (2) are transferred and that holds the transferred blood elements.

Description

technical field [0001] The present invention relates to a blood bag system and a blood processing method for preparing blood component preparations for blood transfusion, such as red blood cell concentrate (CRC: Concentrated Red blood Cell, hereinafter referred to as CRC), concentrated platelet Plasma (PC: Platelet Concentrated, hereinafter referred to as PC), platelet-poor plasma (PPP: Platelet Poor Plasma, hereinafter referred to as PPP), platelet-rich plasma (PRP: Platelet Rich Plasma, hereinafter referred to as PRP), and the like. Background technique [0002] Conventionally, blood component preparations have been prepared by removing leukocytes from blood collected from a donor and centrifuging the leukocyte-depleted blood. For example, Patent Document 1 describes a recovery method and recovery device in which blood flows to a leukocyte removal filter by means of a mechanism that sends blood from a blood inlet port, leukocytes are captured by the leukocyte removal filte...
