FLUID MEASUREMENT DEVICE AND SAMPLE ANALYSIS DEVICE COMPRISING SAME

Title:

FLUID MEASUREMENT DEVICE AND SAMPLE ANALYSIS DEVICE COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2020/137226

Kind Code:

A1

Abstract:

In this fluid measurement device, first and second valves are connected to first and second parts of a measurement pipeline having a prescribed volume. Each valve of the fluid measurement device has a first and second port that are such that when the valve is closed, the internal volume of the first port is smaller than the internal volume of the second port, and the first ports are connected to the ends of the measurement pipeline. As a result, it is possible to make the amount of sample liquid that enters into the ports of the valves smaller and enhance measurement accuracy. If the fluid measurement device is used as a dilution mechanism, a sample analysis device can be provided that has inexpensive valves, a short operation time, and suppressed dilution precision degradation.
