Abstract
An apparatus for obtaining and analyzing a blood sample is presented. The apparatus comprises an integrated drive unit having a common drive source and a drive force transmission gearing that couples a lancet drive, a device for advancing a magazine, and a sample transfer device to the drive source. A tensioning rotor and a drive rotor are mounted so that they are rotatable coaxially to one another. A first cam control converts the rotation of the drive rotor into a radial forward and reverse movement of a drive rod. A second cam control converts the rotational movement of the tensioning rotor into a linear movement of a link slide. A switching link moved by the link slide rotates the magazine an additional step. A third cam control converts the rotational movement of the tensioning rotor into a linear movement of a pressure tappet perpendicular to the piercing axis.
