  • Individual calibration of blood glucose for supporting noninvasive self-monitoring blood glucose
    Patent number: 6309884
    Abstract: A method is provided for calibrating a noninvasive glucose monitor for prospective noninvasive glucose determination. Spectroscopic transflectance readings are measured on the patient's skin using a noninvasive glucose monitor. The patient's blood glucose level is measured with an invasive glucose monitor. The noninvasive and invasive measurements are correlated to form an individual algorithm for each patient. Preferably, the position of the patient's skin with respect to the probe of the noninvasive monitor is spatially adjusted while collecting the transflectance measurements such that multiple readings are taken on the patient's skin. The measurements are preferably taken over a period of time and over a plurality of glucose levels in the patient.

  • Method and apparatus for non-invasive blood glucose sensing
    Patent number: 6088605
    Abstract: A method and apparatus (12) for the non-invasive sensing of blood glucose levels includes apparatus (10) which moves the forearm of the patient in a controlled incremental manner to take a plurality of spectral skin measurements and averaging the measurements for the purpose of accounting for biological differences that exist in the patient's skin.
