Title:
DEVICE FOR FORMING DROPLETS AND METHOD FOR FORMING DROPLETS
Document Type and Number:
WIPO Patent Application WO/2012/011313
Kind Code:
A1
Abstract:
The present invention makes it possible to stably obtain uniform droplets (21) and embolus particles (25) in large quantities. Disclosed is a device for droplet formation (1) which comprises: a dispersed-phase outlet (101a) through which a dispersed-phase material (2), e.g., an aqueous gelatin solution, is discharged; continuous-phase outlets (111a, 121a) through which a continuous-phase material (3), e.g., an oil, is discharged; a confluence part (131) which communicates with the dispersed-phase outlet (101a) and the continuous-phase outlets (111a, 121a) and in which the dispersed-phase material (2) is caused to flow into the liquid of the continuous-phase material (3) at a given static pressure; and a droplet formation part (132) which has been disposed on the downstream side of the confluence part (131) and in which the dispersed-phase material (2) is allowed to become droplets by means of cohesive force.
