Title:
FLUID HANDLING DEVICE, METHOD FOR MANUFACTURING SAME, AND METHOD FOR INTRODUCING FLOWABLE MEDIUM TO FLUID HANDLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/145208
Kind Code:
A1
Abstract:
Provided is a fluid handling device that can fill a fluid into not only a specific flow path, but also a connecting flow path branching therefrom. This fluid handling device has a main flow path, a first flow path, and a first connecting flow path communicating with the main flow path and the first flow path, wherein: the main flow path is a flow path to which a fluid A filled into the main flow path and the first connecting flow path is introduced; and when the fluid A introduced to the main flow path is introduced to the first connecting flow path from the main flow path, the Laplace pressure PL1 acting on the interface between the fluid A and a fluid B pre-filled into the first connecting flow path satisfies condition 1. (Condition 1) PC>PL1
PC: The internal pressure at the branching portion of the main flow path with the connecting flow path
PL1: The Laplace pressure when the dynamic contact angle θ between the fluid A introduced from the main flow path to the connecting flow path and the inner wall of the connecting flow path is set to be less than π
