  • Patent number: 7297241
    Abstract: The invention relates to a method and device for the monitoring of a medical microsample in the flow measuring cell of an analyzer with regard to position and absence of bubbles by means of an alternating voltage applied to the measuring cell, the measuring cell being provided with a multitude of electrode systems placed one behind the other, each system comprising a number of single electrodes for measuring a substance contained in the microsample by means of a measurement voltage which essentially is a DC voltage. To monitor the exact position of the microsample and/or to detect air bubbles in the area of each electrode system, the alternating voltage and the measurement voltage are simultaneously and directly applied to the single electrodes of the corresponding electrode system, and the measured AC component respectively the measured impedance gives a measure for the position of the microsample and the absence of bubbles.

  • Patent number: 7291107
    Abstract: A system for recommending insulin bolus quantities to an insulin user includes a display unit and memory unit coupled to a control circuit with a user blood glucose target stored in the memory unit. The control circuit is programmed to receive the user's current blood glucose value, to determine and display via the display unit a recommended correction insulin bolus quantity if the current blood glucose value exceeds the blood glucose target, to compute a difference value as the current blood glucose value less the blood glucose target, and to produce a modified blood glucose target as a sum of the blood glucose target and the difference value for a lock-out time period if the difference value is positive. Additional correction insulin bolus quantities may be recommended during the lock-out time period if the user's current blood glucose value exceeds the modified blood glucose target.

  • Patent number: 7291159
    Abstract: System for withdrawing body fluid from a body part in particular the finger pad, comprising a compression unit that is deformed when the body part is pressed against it and increases the internal pressure in a region of the body part, and a withdrawal device. Deformation of the compression unit partially converts the primary pressing movement into a secondary movement which leads to an increase in the internal pressure in a region of the body part. The invention also comprises a system for stimulating the outflow of body fluid using a deformable compression unit.
