A platelet collection apparatus (1) has a function of determining whether there is a tendency to increase or decrease in the number of collected platelets by using data, related to the concentration of platelets, obtained from a turbidity sensor (14), an expected number of to-be-collected platelets or a value related thereto; and a function of decreasing the amount of platelets to be collected in a subsequent platelet collection operation after plasma containing high-concentration platelets is collected in a plasma collection operation, if the function of determining on an increase/ decrease tendency in the number of collected platelets determines that there is a tendency to increase in the number of collected platelets. <IMAGE> |
