Title:
MICRODROPLET/BUBBLE GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/168130
Kind Code:
A1
Abstract:
The present invention provides a microdroplet/bubble generation device obviating the need for individual through holes corresponding to a droplet- or bubble-generating channel. Unlike conventional devices where droplet generation channels have been disposed on a two-dimensional plane, arranging such channels three-dimensionally provides channels that have been disposed at higher density than conventionally possible. The microdroplet/bubble generation device is provided with a slit and a plurality of rows of microchannels, wherein: the slit is a continuous phase-supplying slit, a dispersed phase-supplying slit, or a discharging slit; the plurality of microchannels are disposed so as to interconnect a terminus of the slit and two supply ports at both sides, or a supply port and a discharge port; and at the place of connection of the microchannels and the slit, a dispersed phase is sheared with continuous phase flow acting as a driving force, generating dispersed phase microdroplets or bubbles which are collected from the discharge port.
