  • 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.

  • Publication number: 20120199498
    Abstract: An electrochemical-based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (e.g., a whole blood sample) includes an electrically-insulating substrate, at least one working electrode disposed on the electrically-insulating substrate and a graded enzymatic reagent layer disposed on the at least one working electrode. The graded enzymatic reagent layer includes an upper reaction grade that contains an enzyme. The graded enzymatic layer also has a lower spacer grade devoid of the enzyme, the lower spacer grade disposed between the upper reaction grade and the working electrode such that the upper reaction grade is spaced equidistant from the working electrode by the lower spacer grade by a predetermined distance during use of the electrochemical-based analytical test strip.

  • Patent number: 7807031
    Abstract: An improved disposable glucose test strip for use in a test meter of the type which receives a disposable test strip and a sample of blood from a patient and performs an electrochemical analysis is made using a non-conductive integrated reagent/blood separation layer containing a filler, an enzyme effective to oxidize glucose, e.g., glucose oxidase, and a mediator effective to transfer electrons from the enzyme. The integrated layer formulation is printed over a conductive carbon element to form a working electrode. The filler, for example a silica filler, is selected to have a balance of hydrophobicity and hydrophilicity such that one drying it forms a two-dimensional network on the surface of the conductive element. The response of this test strip is essentially temperature independent over relevant temperature ranges and is substantially insensitive to the hematocrit of the patient.

  • Publication number: 20080318193
    Abstract: A device for training a user in recognition of the user's bodily fluid analyte concentration and concentration trends (such as the user's whole blood glucose concentration and concentration trends) includes an analyte monitoring module, a control module and a sensation generation module. The analyte monitoring module is configured to monitor the user's bodily fluid analyte concentration and to output a monitor signal corresponding to the user's bodily fluid analyte concentration. The control module is configured to receive the monitor signal, convert the monitor signal into a sensation instruction signal corresponding to the user' bodily fluid analyte concentration, and output the sensation instruction signal. The sensation generation module configured to receive the sensation instruction signal and to generate a user-perceived sensation (e.g., a user-perceived vibratory sensation) corresponding to the user's bodily fluid analyte concentration.
