Abstract

PURPOSE:To dispense a specified quantity of sample urine, for example, accurately by shifting the forward end part of a liquid sampling pipe vertically so that a sampling position and a retracting position can be taken. CONSTITUTION:Upon receiving an input, a controller 48 shifts a urine receiver 27 to a position optimal for a subject and then shifts the receiver 27 under a urine suction unit 21. When the receiver 27 is shifted downward, the unit 21 develops a urine suction tube 30. Since a solenoid valve of a temporary urine storage tank 22 is opened to communicate with the atmosphere, the urine intrudes from the receiver 27 into the tube 30 as the tube 30 lowers. At a moment when the forward end of the tube 30 abuts against the bottom face of the receiver 27, the urine in the tube 30 is as deep as the urine in the receiver 27 and thereby the solenoid valve is closed. In this regard, following relationship is satisfied; cross-sectional area (s) of the tube/bottom area S of the receiver 27=1/n. The tube 30 is then lifted along with the intrudes urine and a suction unit 23 sucks the urine in the vicinity of the forward end of the tube 30 and feeds the urine through a piping 25 into a urine tank 22. The urine is discharged through a discharge pipe 46 into a lower vial bottle 10 upon opening of the solenoid valve. The weight of the urine is measures 47 instantaneously to finish the dispensation of urine.
