NON-INVASIVE METHOD FOR EVALUATING CHANGES IN GLUCOSE LEVEL IN HUMAN BLOOD AND AN APPARATUS FOR IMPLEMENTING THE METHOD

摘要

1. A non-invasive method for assessing changes in the level of ΔG glucose in the blood of a person in the interval Δt time, including the stages in which:! placing the first tetrapolar electrode device parallel to the direction of the muscle fibers in contact with the skin of said person covering part of the soft tissue, including muscle fibers; ! place a second tetrapolar electrode device perpendicular to the direction of the muscle fibers in contact with the skin of said person covering said portion of soft tissue; ! measured over a time interval Δt:! - the relative change ΔС║, LF / C║, LF values of С║, LF conductivity of the mentioned tissue parallel to the direction of muscle fibers at a low frequency using the first tetrapolar electrode device; ! - the relative change ΔС┴, LF / C┴, LF values of C┴, LF conductivity of the mentioned tissue perpendicular to the direction of muscle fibers at a low frequency using a second tetrapolar electrode device; ! rate ΔG as:! - 0,0 if ΔС║, LF / C║, LF≈ΔС┴, LF / C┴, LF! - + and if ΔС║, LF / C║, LF ΔС┴, LF / C┴, LF! - -a if ΔС║, LF / C║, LF ΔС┴, LF / C┴, LF! where:! "a" is in the range of 0.15-1.0 μm / l · s; ! low frequency is in the range of 1 · 104 Hz - 5 · 104 Hz; and! “≈” means "equals within the range of +/- 2.5% - +/- 7.5%." ! 2. The method according to claim 1, in which Δt is in the range of not more than 15 s. ! 3. The method according to claim 1, additionally containing stages in which:! Measure during the interval Δt time:! - the relative change ΔС║, HF / C║, HF of the value of С║, HF of the conductivity of the said tissue parallel to the direction of muscle fibers at a high frequency using the first tetrapolar electrode device; ! relative change ΔС�
