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.
A liquid collecting system having a liquid collecting apparatus for collecting a liquid to be measured, as separated in a time series, comprising (a) a flow path through which the liquid to be measured flows, (b) an extracting device provided in an intermediate position of the flow path to insert a gas or a liquid other than the liquid to be measured, as separators, at designated predetermined intervals, thereby to take out the liquid to be measured, as separated in the time series, and a dripping device for successively dripping the taken-out liquid to be measured, a liquid storage device having a plurality of grooved flow paths for storing the dripping liquid individually, and a control device for performing positional control, as interlocked to the dripping, to locate the grooved flow paths successively in a dripping position;
