  • Patent number: 8815076
    Abstract: A method and system is provided to allow for determination of substantially Hematocrit independent analyte concentration. In one example, an analyte measurement system is provided that includes a test strip and a test meter. The test strip includes a reference electrode and a working electrode, in which the working electrode is coated with a reagent layer. The test meter includes an electronic circuit and a signal processor. The electronic circuit applies a plurality of voltages to the reference electrode and the working electrode over respective durations. The signal processor is configured to determine a substantially hematocrit-independent concentration of the analyte from a plurality of current values as measured by the processor upon application of a plurality of test voltages to the reference and working electrodes over a plurality of durations interspersed with rest voltages lower than the test voltages being applied to the electrodes.

  • Patent number: 8460537
    Abstract: A method for determining an analyte concentration in blood is described that reduces the effects of hematocrit using a test strip attached to a test meter. The test strip includes a working electrode and a reference electrode. The test meter applies a test voltage between the working electrode and the reference electrode. After a user applies a blood sample containing an analyte onto the test strip, the test meter measures a plurality of test currents for a test time interval.

  • Patent number: 7516845
    Abstract: A medical device package includes a body with at least one chamber therein, a proximal end and a distal end. The medical device package also includes at least one deformable projection within the chamber(s). Furthermore, the deformable projection is configured to deform resiliently upon contact with a medical device during insertion of the medical device into the chamber and, thereby, removably retain the medical device within the chamber.
