  • Patent number: 10197524
    Abstract: Methods are disclosed for scaling body fluid analysis data to correct and/or compensate for confounding variables such as hematocrit (Hct), temperature, variations in electrode conductivity or combinations thereof before providing an analyte concentration. The scaling methods utilize current response data obtained from an AC block applied prior to a DC block to minimize the impact of such confounding variables upon the observed DC current response before creating descriptors or algorithms. The scaling methods therefore compensate the measured DC current by using data from the AC block made on the same sample. Also disclosed are devices, apparatuses and systems incorporating the various scaling methods.

  • Publication number: 20180348159
    Abstract: A biosensor including a capillary chamber having an inner boundary, a working electrode including an effective working electrode portion positioned within the capillary chamber, and a counter electrode including an effective counter electrode portion positioned within the capillary chamber, and with the working and counter electrodes each having a neck that constitutes the sole portion of the electrodes that extends across the inner boundary and out of the capillary chamber. In one embodiment, the effective working electrode portion defines an average working electrode width, and the working electrode neck defines a working electrode neck width that is reduced relative to the average working electrode width.

  • Publication number: 20170357766
    Abstract: A medical system is disclosed, which can be useable in particular for monitoring and/or controlling at least one bodily function of a user. The medical system comprises a control device and at least one medical user element embodied separately from the control device. The medical user element and the control device are designed to exchange data wirelessly. The medical system is designed to enable an automatic assignment step, wherein an exchange of personal data between the medical user element and the control device is enabled by the automatic assignment step. The medical system is furthermore designed to automatically initiate the automatic assignment step by means of an assignment coupling between the medical user element and the control device. The medical system is furthermore designed to enable a separation of the assignment coupling for medical operation of the medical system after the assignment step.

  • Publication number: 20170252513
    Abstract: Methods and systems are disclosed for estimating a glucose level of a person having diabetes and selecting automatically open-loop and closed-loop control for a connected therapy delivery device. The method may comprise analyzing measured glucose results and corresponding impedance values received from a glucose sensor coupled to the person with a probability analysis tool implemented by a microcontroller to determine a total quality score that is based on the minimum constraint of a probability of glucose sensor accuracy determined measured glucose results and a probability of sensing quality determined from the impedance values. The microcontroller may estimate the glucose level of the person with a recursive filter based on the plurality of measured glucose results weighted with the total quality score and select automatically either open-loop control or closed-loop control for the connected therapy delivery device based on the value of the total quality score.

  • Patent number: 9594045
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods further allow one to provide an error code or correct and/or compensate for interferents such as an antioxidant before providing an analyte concentration. The measurement methods utilize information obtained from test sequences having at least one DC block, such as a slow-ramped bi-polar waveform, where a closed circuit condition is maintained during the DC block. The methods use information relating to status of a redox mediator feature during the electrochemical analysis to provide an antioxidant failsafe if the antioxidant is interfering with the analyte concentration. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.
