CONTROL OF FLUID FLOW IN A MICROFLUIDIC SYSTEM

摘要

The invention relates to the means for controlling the processing of a sample fluid (S) in a microfluidic system (110). The sample fluid (S) is introduced into an inlet port such that air is captured in the microfluidic system (110). Further advancement of the sample fluid(S) is only possible after a venting port (115) has controllably been opened, wherein said flow comes to a rest at a fluidic stop (130) before reaching the venting port (115). In a particular embodiment, the microfluidic system (110) is disposed in a cartridge (100), and the venting port (115) is covered by a foil (102). After insertion of the cartridge (100) into a sensor apparatus (150), said foil can be pierced, thus starting the filling of the microfluidic system (110) and processing of the sample fluid.
