  • Publication number: 20120271126
    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.

  • Patent number: 8287467
    Abstract: The invention relates to a puncturing system for generating a puncture wound for obtaining a sample of a body fluid, comprising a press-on part to be pressed onto a body part in which a puncture wound is to be generated, a triggering means, by the actuation of which a user can trigger a puncturing motion of a puncturing element after the press-on part is pressed on, and a testing facility for determining at least one test parameter on which a sample-obtaining probability depends. A securing facility is also provided that, in a locked state, locks the triggering means such that no puncturing motion can be triggered, and, in a triggering state, releases the triggering means such that a puncturing motion can be triggered by actuation thereof, whereby the securing facility is transitioned from the locked state to the triggering state by the testing facility when the test parameter determined by the testing facility meets defined minimum requirements.

  • Patent number: 8114028
    Abstract: An analyte determination analysis system with a disposable integrated sample acquisition and analysis element is disclosed. A piercing element has a tip for generating a bodily puncture wound and a test strip having a body fluid sample receiving zone to perform an analysis on a body fluid sample. A reusable analysis instrument comprises a coupling unit that couples the integrated sample acquisition and analysis element to a drive that drives a piercing element in a piercing movement comprising two phases: a propulsion phase wherein the piercing element moves on a puncture path in a puncture direction and a retraction phase wherein the piercing element moves opposite to the puncture direction after reaching a reversal point. A measuring and analysis unit measures a variable characteristic for the determination of the analyte and determines a desired analysis result on the basis of the measurement. The sample receiving zone of the test strip forms a sample contact.

  • Patent number: 8114029
    Abstract: An actuator for driving a test element is disclosed. The test element can comprise a lancet for perforating the skin of a living organism. The actuator can comprise an engaging part for engaging and driving the test element in a lancing motion. The actuator can further comprise a lancing actuator and a lancing spring. The lancing actuator can bias the lancing spring by executing a forward movement and thereby can exert a biasing force on the engaging part. The actuator can further comprise a latch element. The latch element can be a force-sensitive latch element for exerting a retention force to hold back the engaging part. The retention force can counteract the biasing force. The latch element can release the engaging part when the biasing force exerted by the lancing actuator exceeds the retention force exerted by the latch element, thereby allowing the test element to perform the lancing motion.
