The microfluidic peristaltic pump, a method as well as a pumping system

摘要

The invention relates to a microfluidic peristaltic pump (100), which comprises a supply channel (10), a first pump chamber (20), which, via a first channel (30) with the inlet conduit (10) is operatively connected, and a first diaphragm (40), a second pump chamber (50), which, via a second channel (60) with the inlet conduit (10) is operatively connected, and a second diaphragm (70), wherein the fluidic resistance of the first channel (30) from the fluidic resistance of the second channel (60) is different, and in this case, each channel (30, 60), a throttle function is realized such that the respective diaphragms (40, 70) when a pressure in the inlet conduit (10) in a time sequence for the implementation of a pumping function are deflected.
