Abstract

A blood component sampling cassette which can be more efficiently manufactured at lower cost as compared to a typical cassette, a blood sampling circuit set, and a blood component sampling system. A blood component sampling cassette () includes a cassette main body () made of a soft material to which heat sterilization is applicable. The cassette main body () is provided with a retransfusion line (). The retransfusion line () is provided with a reservoir () configured to temporarily store a blood component to be returned to a blood donor. The reservoir () is pressed by a retransfusion pump () to discharge the blood component from the reservoir ().
