Abstract

The invention relates to a method for filling a microfluidic device (3) using a dispensing system (2), said method comprising at least the following steps: (a) transporting the solution from the container (6) to the sample application opening (13) of the microfluidic device (3) via the nozzle (11) of the dispensing system (2) using a micropump (10); (b) further transporting the solution into the measuring region of the microfluidic channel (14) of the microfluidic device (3); (c) measuring a light signal in the measuring region of the microfluidic device (3) using at least one photosensitive sensor (4) with a plurality of photodetectors (5); and (d) deactivating the micropump (10) if the light signal is detected and / or if the light signal changes.

Description

technical field [0001] The invention relates to a method for filling a nozzle of a dispensing system of a testing system comprising a dispensing system, a microfluidic device and at least one photosensitive sensor with a plurality of photodetectors, as well as a testing system. Background technique [0002] Many point-of-care testing systems in in vitro diagnostics require manual infusion of different solutions into sample vessels. For example, WO2012 / 080339A1 discloses a measuring instrument, in which three different reagents in a volume range of 10 μl need to be manually and sequentially dropped in during the test. The disadvantage of this manual instillation is that the hands are used for a long time when the test is done and the working capacity is restricted. In addition, manual instillation hides a certain risk of producing erroneous results due to little robustness and reproducibility. Furthermore, WO 2012 / 080339 A1 also describes a discharge device for reagents, wh...
