Abstract
An autonomic nervous activity monitor capable of predicting occurrence of abnormal reaction depending on autonomic nervous activity and used for medical practice and the like is provided. A blood component collecting apparatuscarries out frequency analysis to a pattern of heartbeat which is acquired by an ECGfrom a donor, and calculates a high frequency component value [msec] defined as an indicator for parasympathetic activity and a ratio value of a low frequency component to the high frequency component defined as an indicator for sympathetic activity to detect a change in these values on a time-series base. When a judgment circuitpredicts that abnormal reaction may occur to a donor after blood collection operation is started, a controllercontrols a pumpto decrease a blood drawing or blood returning speed, or, to stop blood drawing or blood returning operation.
