Abstract:
1. Fluid management apparatus comprising: a substrate having a first surface and a second surface which is opposite to the first surface; a plurality of fluid inlets which are formed in a first pattern in the first surface of the substrate and comprise first opening cross-sections; a plurality of fluid outlets which are formed in a second pattern, which is different from the first pattern, in the second surface of the substrate and comprise second opening cross-sections which are smaller than the first opening cross-sections; and a plurality of fluid ducts formed in the substrate, each fluid duct connecting a fluid inlet with a fluid outlet such that each fluid outlet is in fluidic communication with exactly one fluid inlet; wherein the first pattern defines spacings between adjacent fluid inlets which are larger than spacings between adjacent fluid outlets defined by the second pattern.
