  • Patent number: 7322998
    Abstract: A device for withdrawing blood for diagnostic purposes including a lancet and a lancet drive having a loadable elastic drive spring provided within an elongated housing. A relaxing motion of the drive spring is converted into a puncturing motion to move the lancet at high speed in a puncturing direction until its tip exits out of an opening of the housing. The device includes a transmission in the housing that has an input side that transforms the motion of a loading element along a linear loading path into a rotational motion of a lancet drive rotor to load the lancet drive rotor by tensioning the drive spring. When the lancet drive is triggered, the output side of the transmission converts a rotational motion of the lancet drive rotor, driven by the drive spring, into the puncturing motion in a direction along the main axis.

  • Patent number: 7169600
    Abstract: The invention concerns an arrangement for determining the concentration of glucose in a tissue fluid. In the microdialysis technology used for this purpose, perfusate-containing glucose is transported in intermittent delivery pulses through a microdialysis probe inserted into the tissue fluid and dialysate obtained in this process is passed to a measuring cell to record the glucose content. In order to achieve an exact determination of glucose even with a reduced dialysis period, it is proposed that the starting content of glucose in the perfusate is adapted to the glucose content of the tissue fluid by means of a control device in accordance with a command variable derived from the measurement signals of the measuring cell. When the control deviation is negligible the momentary starting content of glucose in the perfusate can be determined as a measure for the glucose content of the tissue fluid.
