Title:
FLOW PATH STRUCTURE, MEASUREMENT UNIT, METHOD FOR MEASURING LIQUID TO BE MEASURED, AND DEVICE FOR MEASURING LIQUID TO BE MEASURED
Document Type and Number:
WIPO Patent Application WO/2017/022305
Kind Code:
A1
Abstract:
Provided is a flow path structure capable of achieving a reduction in the size of a device into which the flow path structure is incorporated, and improving portability. This flow path structure 1 is provided with: a liquid storage part 10 provided with a liquid-accommodating part 11 capable of accommodating a liquid, and a flow-out part 12; a separation element-accommodating part 20 including a separation element between two open ends 21, 22; a supply flow path 30 which is connected to the flow-out part 12 of the liquid storage part 10, and one open end 21 of the separation element-accommodating part 20, and which allows the liquid storage part 10 to communicate with the separation element-accommodating part 20; and a discharge flow path 40 connected to the other open end 22 of the separation element-accommodating part 20. The supply flow path 30 is provided with: a liquid storage part-side flow path 31 connected to the flow-out part 12 of the liquid storage part 10; a separation element-side flow path 32 connected to the separation element-accommodating part 20; and an injection part 33 which is positioned between the liquid storage part-side flow path 31 and the separation element-side flow path 32, and which is capable of introducing a liquid to be measured into the supply flow path 30. The liquid storage part 10 is provided with a pressure transmission part 13 with which an external force applied to the flow path structure 1 can be transmitted as a pressure fluctuation inside the liquid storage part 10. The liquid accommodated inside the liquid storage part 10 is capable of being made to flow out from the flow-out part 12 to the supply flow path 30 on the basis of the pressure fluctuation inside the liquid storage part 10.
