The specific embodiment
Now in conjunction with the accompanying drawings the present invention is further described:
This portable non-invasive blood sugar monitoring instrument is made up of near infrared light source unit, light-path unit, photoelectric conversion unit, electric pathway unit, data processing unit five parts.The near infrared light source unit produces required near-infrared light beam, finish the collection and the transmission of near infrared light through the light-path unit, the near infrared light of collecting that has blood glucose information is finished the conversion of optical signal to the signal of telecommunication through photoelectric conversion unit, finishes signal filtering, integration, amplification and mould/number conversion through the electric pathway unit then; Through data processing unit the digital signal that obtains is implemented mathematical operation at last, thereby measure blood sugar content.
The near infrared light source unit is made up of power supply, on and off switch, halogen tungsten lamp.Power supply both can have been used the rechargeable battery of 12V, also can use the civil power of 220V, gave microprocessor and halogen tungsten lamp power supply by on and off switch.There is thermostat to be used for controlling the temperature of giving out light of halogen tungsten lamp on the halogen tungsten lamp, makes it have stable luminous intensity, reducing light source fluctuation, and converge near infrared light to fiber coupler by a reflecting mirror to the detection system influence on signal-to-noise ratio (SNR).
The light-path unit is made up of optical fiber, fibre-optical probe, grating.The near-infrared light beam that sends from halogen tungsten lamp enters fibre-optical probe through fiber coupler, utilize advantage leaded lights such as fiber-optic transfer efficient height, loss be low, fibre-optical probe adopts donut topology layout design, the internal ring of probe is that an optical fiber is formed incident optical, and outer shroud is to accept optical fiber a plurality of the composition around the equally distributed fibre bundle of internal ring center certain distance.This placement scheme has effectively been concentrated incident intensity, makes light vertically inject human skin tissue by incident optical; Accept the collection that optical fiber has been got rid of the veiling glare that major part not through the deep tissues diffuse scattering and only reflects by epidermis again around internal ring center certain distance is equally distributed simultaneously.A grating that is installed in the fixing optical bench is divided into monochromatic light with the diffusion light of collecting from polychromatic light.
Photoelectric conversion unit is made up of the detector of an InGaAs array.The InGaAs detector has the temperature chiller, and this helps reducing and suppressing noise, improves the detection system signal to noise ratio; The InGaAs detector converts optical signal to the signal of telecommunication.
The electric pathway unit is made up of preamplifier and A/D converter.From InGaAs detector electrical signal converted, through filtering, amplification, the Integral Processing of preamplifier, make signal reach the amplitude that detects identification, realize the transformation of analogue signal by A/D converter again to digital signal.
Data processing unit is topmost unit in the instrument, and it is made up of microprocessor, memorizer, statistical analysis switch, startup/reset switch, demonstration and precaution device and communication and printing interface.Startup/reset switch is used for control microprocessor action, and digital signal is compared with the peg model in the memory, infers and calculates blood sugar content, the result is stored in the memorizer, and the result delivered to shows and precaution device shows and exports.Show with precaution device to also have warning function, when blood sugar content in human body euglycemia content range, show " normally "; When its not in normal range the time, send " early warning ".The statistical analysis switch has intelligent statistical function, be used to add up maximum, minima and the meansigma methods of the blood sugar content of recent mensuration, and draw the blood sugar content change curve, be presented on demonstration and the precaution device, the patient can know the variation tendency of understanding self blood sugar content, can instruct the patient to take medicine.
When this monitor was worked: power supply 6 was by switch 7 control halogen tungsten lamp 8 and microprocessors 20, the near-infrared light beam that halogen tungsten lamp 8 sends enters optical fiber by fiber coupler, through optical fiber light-guiding to fibre-optical probe 9, the near-infrared light beam is vertically injected measuring point 10 by the incident optical 21 of fibre-optical probe 9, be in equally distributed 16 reception optical fiber 22 collections on the same annulus with incident optical 21 at a distance of 0.07cm then, through grating 11 polychromatic light is divided into monochromatic light, the absorption intensity of measuring blood correlation absorption band, optical signal converts the signal of telecommunication to by photodetector 12, carry out filtering through preamplifier 13 then, amplify, Integral Processing, change to digital signal by A/D converter 14 realization analogue signals again, digital signal after the conversion is delivered to microprocessor 20, by comparing with peg model, calculate the blood sugar content of human body, the result is kept at memorizer 16, be simultaneously displayed on demonstration and precaution device 15 and early warning, can be used for printing monitoring result and storage Monitoring Data by communication and printing interface 19 at last; Can finish repeatedly monitoring continuously by startup/reset switch 17.
