    Abstract: A blood component collection system, which is one form of a biological component collection system, is equipped with a centrifugal separation device and a biological component collection device. The biological component collection device comprises a pressed soft portion pressed by a load detecting unit. The centrifugal separation device includes a collection and returning pump, and a control unit having an internal pressure computation unit which calculates a circuit internal pressure of the biological component collection device on the basis of a detection value of the load detecting unit. The internal pressure computation unit performs a zero reset process of setting a pressure value corresponding to the detection value of the load detecting unit, so as to become zero at each instance of a predetermined timing at which the collection and returning pump is stopped.
