  • Publication number: 20210295515
    Abstract: A method for generating a module configured to determine concentration of an analyte in a sample of a body fluid is disclosed. The method includes providing a first set of measurement data derived from images of one or more test strips indicating a color transformation in response to a body fluid containing an analyte. The images can be recorded by multiple devices with differing cameras, software and/or hardware device configurations for image recording and image data processing. A neural network model can be generated in a machine learning process applying an artificial neural network and a module configured to determine concentration of an analyte in a second sample of a body fluid can be generated. Further, the present disclosure includes a system for generating the module as well as a method and a system for determining concentration of an analyte in a sample of a bodily fluid.

  • Patent number: 9594052
    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, where DC block includes at least one recovery potential, and where a closed circuit condition of the electrode system is maintained during the DC block. The methods use information relating to status of a redox mediator during the electrochemical analysis to provide a statistical antioxidant failsafe using either a classifier or a discriminator to determine whether the antioxidant is interfering with the analyte concentration. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.

  • Patent number: 8818782
    Abstract: A system for developing patient-specific therapies based on dynamic modeling of patient-specific physiology and method thereof are disclosed. The system includes software modules configured to provide access via a computer to one or more data collection protocols defining at least a type of patient-specific data to be collected and a manner in which the patient-specific data is to be collected, and to information from which one or more patient-specific models, configured to simulate one or more aspects of the patient's physiology, is developed. Another software module of the system is configured to provide access via the computer to one or more software tools that apply patient-specific data, collected according to the one or more data collection protocols, to the one or more patient specific models to determine therefrom one or more patient-specific therapies.

  • Patent number: 8712748
    Abstract: A diagnosis, therapy and prognosis system (DTPS) and method thereof to help either the healthcare provider or the patient in diagnosing, treating and interpreting data are disclosed. The apparatus provides data collection based on protocols, and mechanism for testing data integrity and accuracy. The data is then driven through an analysis engine to characterize in a quantitative sense the metabolic state of the patient's body. The characterization is then used in diagnosing the patient, determining therapy, evaluating algorithm strategies and offering prognosis of potential use case scenarios.
