The invention also discloses a blood glucose measuring device using said measurement method.
Description
Technical field
The present invention relates to a kind of blood sugar measuring method and hardware unit.
Background technology
Common heart sugar measuring method will be drawn blood, and measures inconvenience, is unsuitable for measuring at any time.Existing non-destructive measuring method is not because adopt suitable anti-interference method; Some new theoretical methods are too complicated again and can not prove effectively, so there not be the application of getting well.
Summary of the invention
The present invention overcomes the inaccurate defective of traditional blood sugar measuring method, a kind of blood sugar measuring method is provided, with far red light to skin exposure, use two concentric light transmitting fibers and reflection crystal, sending into inside by the far-infrared spectrum that attenuated total reflection is caught has the screening ball of specific wavelength absorption plant and catoptron to carry out repeatedly reflection-absorption, need the light signal of wavelength to send the most at last and analyze, calculate the content of blood sugar.
The infrared waves wavelength X is 0.75-1000 μ m (1 μ m=10 between visible light wave and microwave wavelength
-4Cm).Wherein: far infrared is 0.75-2.5 μ m, in infrared be 2.5-25 μ m, 4000-400cm
-1, near infrared is 25-1000 μ m.
The wavelength of infrared waves is used wave number (cm always
-1) expression.The definition of wave number is: the number of contained light wave in per 1 cm range.Wave number=10
4/ λ (μ m).Therefore, 2.5 mum wavelengths are equivalent to 10
4/ 2.5cm
-1, i.e. 4000cm
-1, and 25 μ m are equivalent to 400cm
-1
The measuring method in past adopts near infrared light or near partially near infrared mid-infrared light to measure more, and test finds that the anti-interference of far red light or near partially far mid-infrared light is stronger.
Described blood sugar measuring method uses the far red light of 2 to 2.5 mum wavelengths to be used for laser-bounce and collection.By attenuated total reflection and the screening ball to 4200-4800cm
-1The far red light analysis of spectrum.The method of described attenuated total reflection be with from the light focus reflection of infrared light supply to crystal, reenter the surface that is mapped to sample because the refractive index of sample is less than the refractive index of crystal, incident angle is bigger than critical angle, the light generation total reflection phenomenon that is reflected fully.Directly reflected during in irradiate light, but returned the surface again after inciding the certain degree of depth of sample, so collect the attenuated total reflection spectrum that attenuated total reflection light just can obtain sample to sample surperficial.
Described blood sugar measuring method, sites measured preferentially select tongue, eardrum, refer in the web one or more.Because these positions of test statistics especially tongue and eardrum blood are abundant, moisture and protein is less, disturb less.
Described blood sugar measuring method, by generating two groups of measuring-signals, measure normal human body blood-sugar content for one group, another group is measured the undesired signal of skin, two groups of attenuated total reflection spectrum that obtain are entered the screening ball with diverse location, generation makes wherein one group of anti-phase back effect that superposes with another group, to eliminate wherein interference such as skin, moisture.
Described blood sugar measuring method is transported to light activated element with the spectral signal of exporting, and can reflect the intensity of the spectrum that filters out by the signal magnitude of light activated element output, thereby reacts blood-sugar content.
Described blood sugar measuring method through repeatedly measuring, by demarcating correction measurement parameter and/or statistical measurements to eliminate error, obtains measurement result more accurately.
Described blood sugar measuring method, the computing method of statistical measurements adopt least square method.
A kind of blood glucose measuring device uses described blood sugar measuring method, by ancillary hardware devices such as cpu motherboard, power supply, light transmitting fiber, generating laser, screening ball, light activated element, attenuated total reflection crystal, auxiliary stand, measuring blood content fast.
