MIXER WITH ZERO DEAD VOLUME AND METHOD OF MIXING Russian patent published in 2015 - IPC B01F13/00 

Abstract RU 2554573 C2

FIELD: process engineering.

SUBSTANCE: invention relates to fluid mixers. Microfluid system (1) comprises closed expanding chamber (35) for mixing of fluid, resilient membrane (40) for mixing in said expanding chamber (35). Surface (5) includes at least one channel (20) for communication between first side (10) of surface (5) and closed expanding chamber (35) on second side (15) of surface (5). Note here that channel (20) has first bore (25) to communicate first side (10) of surface (5) with channel (20) and second bore (30) to communicate said channel (20) with closed expanding chamber (35). Said closed expanding chamber (35) is defined by resilient membrane (40) that stops channel second bore (30) when said chamber (35) does not contain fluid. Invention relates also to application of above described microfluid system (1).

EFFECT: improved mixing.
