Blood collecting apparatus

Claim 1

A blood collecting apparatus for collecting blood into a blood container, comprising: blood collecting means; blood collection stopping means; vibrating means for vibrating said blood container; collected blood amount measuring means for measuring the amount of blood collected in said blood container; and control means for starting collecting of blood into said blood container while said blood container is being vibrated by said vibrating means, for receiving the result of measurement performed by said collected blood amount measuring means and data of a set amount of blood to be collected into said blood container, and for receiving a vibration stoppage reference time during which the vibration of said blood container is stopped at a blood collection terminating stage, said control means including: means for setting the vibration stoppage reference time at a time not shorter than a measurement interval of an amount of collected blood between a last measurement time of the amount of collected blood and a next measurement time of the amount of collected blood; a means for calculating, at a midway stage of the blood collection, an amount of blood yet to be collected and a blood collecting speed allowed by a current donor; means for calculating, on the basis of the calculated blood collecting speed, a yet-to-be-collected blood collecting time that corresponds to an amount of blood yet to be collected; means for maintaining stoppage of vibration of said blood container by said vibrating means when a yet-to-be-collected blood collecting time has become not more than the vibration stoppage reference time; and means for causing said blood collection stopping means to stop the action of collecting blood into said blood container when the result of measurement performed in the stoppage condition by said collected blood amount measuring means has reached a set blood collection amount.
