US 2006/0219307 A1 · Micromixer apparatus and method therefor

Abstract

A micromixer used for microfluidic system is provided. The micromixer incorporates a pairs of reciprocating pumps and a pairs of fluidic element for mixing at least two fluids. With such a microfluid mixer, the at least two fluids are mixed when the reciprocating pumps are in their forward strokes by means of the impingement of two pulsation flows. The two fluids are also mixed when the reciprocating pumps are in their backward strokes by means of the generation of the vortexes, and the two fluids are also mixed by means of mass diffusion via a purposeful like-lamella-structure.

Dependent claims

A mixing apparatus, comprising:

a first and a second fluidic elements;
a first and a second micropumps, respectively configured at each of the input of said first and second fluidic elements;
and
a chamber configured between said first and second fluidic elements,
wherein said mixing apparatus outputs a first and a second jets respectively from said first and second fluidic elements into said chamber by means of reciprocations of said first and second micropumps, so that said first and second jets collide with each other and then are mixed during forward strokes of said first and second micropumps, and parts of said mixed jets are respectively pulled back from said chamber to cause flow separation and recirculation in said first and second fluidic elements during reverse strokes of said first and second micropumps.
