ABSTRACT:
Apparatus for collecting blood includes a control device for starting the action of collecting blood into a continuously or intermittently vibrated blood container, to receive a measured collected blood amount and data of a set amount of blood to be collected into the blood container, and also a vibration stoppage reference time during which the vibration of the blood container is stopped at a blood collection terminating stage so as to calculate, at a midway stage of the blood collection, the amount of blood yet to be collected and the blood collecting speed allowed by the current donor, to calculate, on the basis of the calculated blood collection speed, the yet-to-be-collected blood collecting time that corresponds to the amount of blood yet to be collected. The control device maintains the stoppage of vibration of the blood container on the condition that the yet-to-be-collected blood collecting time has become not more than the vibration stoppage reference time, and causes a stopping of collecting blood into the blood container on the condition that the measured collected blood amount, measured in the stoppage condition, has reached the set blood collection amount.
