Abstract
The invention relates to a system for collecting samples and to a method for collecting a liquid sample. The system comprises at least one analytical aid, the analytical aid comprising a lancet and a test element, and the test element having a test field for analysis of the liquid sample. The system for collecting samples comprises a coupling element which can be successively connected to the lancet, in a first position of the analytical aid, and to the test element, in a second position of the analytical aid. The system for collecting samples also comprises a drive unit for moving the coupling element from a rest position to a deployed position, such that the movement of the coupling element is transmitted to the lancet, coupled thereto, in order to execute a puncturing movement, or is transmitted to the test element, coupled thereto, in order to execute a sample recovery movement.
