A sampling system (110) for collecting a liquid sample is proposed which has at least one analytical aid (112). The sampling system (110) has a coupling element (152) for coupling to the analytical aid (112), and at least one drive unit (160) for driving a movement of the coupling element (152) from a rest position to a deployed position. The drive unit (160) comprises an energy converter (162), which is designed to generate a rotation movement with different directions of rotation. The drive unit (160) also has a coupling device with at least one element (194, 218; 242) sensitive to the direction of rotation, wherein the coupling device is designed such that, in a first direction of rotation, it couples the energy converter (162) to a first system function and, in a second direction of rotation different than the first direction of rotation, it couples the energy converter (162) to a second system function different than the first system function. |
