Abstract
A biological component collection system and a circuit internal pressure acquisition method are provided, which are capable of accurately measuring the circuit internal pressure. A centrifugal separation device of a blood component collection system has a first load detecting unit, an internal pressure calculation unit that calculates an internal pressure using the load detected by the first load detecting unit and internal pressure calculation data. The internal pressure calculation unit performs a calculation reflecting a change in the internal pressure calculation data depending on temperature.
