Title:
FLUID TRIGGABLE VALVES
Document Type and Number:
WIPO Patent Application WO/2015/019336
Kind Code:
A3
Abstract:
The present invention relates to a fluid triggerable passive valve for controlling flow of one or more fluids comprising: a volume comprising at least two capillary pressure barriers for respectively pinning a first and second fluid-fluid meniscus, the two capillary pressure barriers dividing the volume in at least three sub volumes, whereby two sub volumes being positioned upstream and one sub volume being positioned downstream with respect to the advancement direction of each respective fluid-fluid meniscus; wherein the capillary pressure barriers are spaced apart such that upon pinning of a first fluid-fluid meniscus on a first capillary pressure barrier and arrival or pinning of a second fluid-fluid meniscus on or at a second capillary pressure barrier, the two menisci touch and thereby coalesce into one fluid-fluid meniscus
