Title:
FLUID DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/003520
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a flow passage device that introduces a solution into a flow passage while suppressing generation of bubbles and can quantify the solution. This device has a pair of substrates which are laminated in the thickness direction and one of which is provided with a flow passage formed by being covered with the other substrate. The flow passage includes a quantifying part that can quantify a solution to a prescribed amount. The quantifying part has: a pair of merging/branching sections each of which is surrounded by a contour conforming to or being parallel to segments connecting the vertexes of a regular triangle in a view along the thickness direction and which cause solution merging or branching; and a connection section which connects the pair of merging/branching sections via respective ones of the vertexes of the regular triangles at the merging/branching sections. Valves for regulating the flow of a fluid in the flow passage are provided to the vertexes of the merging/branching sections where no connection part is disposed.
