Claim Text:
1. A microfluidic mixing device for mixing at least two fluids to form a mixed fluid comprising: a first mixing chamber for receiving the fluids from at least a first and a second fluid paths; a mixing zone upstream from the mixing chamber having the first and second fluid paths; said first and second fluid paths overlapping at first and second discreet points so as to provide mutual fluid communication between the first and second paths at said discreet points, wherein at least one of the first and second fluid paths includes a primary channel and a plurality of divided channels dividing from the primary channel at a first node, and projecting to a second node whereupon said plurality of channels are recombined, wherein a width of the mixing chamber adjacent to an inlet of the first and second fluid paths entering the mixing chamber is equal to or greater than the sum of the widths of the channels of the at least one of the first and second fluid paths immediately upstream of the mixing chamber, and wherein at least one of said divided channels is of a greater flow capacity than at least one of said remaining divided channels.
