Abstract
A blood collecting apparatus includes a cleaning solution piping. The cleaning solution piping feeds into a flow path a heparin solution which is a liquid other than blood to be measured, in order to return the blood present in the flow path to a catheter disposed upstream of a blood inlet of the flow path. Thus, the blood having flowed into the flow path in an amount more than is necessary for blood collection, which corresponds to a portion returned to the upstream catheter of the blood to be measured present in the flow path, can be used in a next blood collection. As a result, the amount of collected blood can be reduced. The liquid to be measured is separated apart by means of a gas, and the flow path is cleaned in a way to leave no impurities in the flow path, thereby preventing impurities from mixing into the liquid to be measured.
