APPARATUS FOR OBTAINING AND ANALYZING A BLOOD SAMPLE WITH A LANCET COUPLING MECHANISM
First Claim
1. An apparatus for obtaining and analyzing a blood sample, the apparatus comprising:
- a housing;
a contact device provided on the housing for pressing against a body part from which the blood sample is to be taken;
a magazine movably mounted on the housing, the magazine comprising a plurality of lancets, wherein each lancet pierces the body part and retracts from the body part to receive the blood sample exiting the pierced body part;
a device for advancing the magazine to bring a lancet into a functional position;
a lancet drive having a drive rod coupled to the lancet located in the functional position, wherein the lancet drive executes a controlled piercing movement along a piercing axis;
test elements assigned to the lancets, wherein each test element receives the blood sample in order to analyze the blood sample; and
an integrated drive unit comprising the lancet drive, the device for advancing the magazine, and a device for generating a sample transfer movement perpendicular to the piercing axis.

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.
