Abstract
The present invention relates to a self-service non-wound blood sugar measurer which comprises an infrared light source, a light passage part, a photoelectric detection converter, an electric passage part and a display part, wherein the infrared light source is composed of an infrared light transmitting tube. The present invention is characterized in that the light passage part comprises two beams of light paths, wherein one beam penetrates through a light filter piece lambda 1 via a reflector, and the other beam penetrates through a light filter piece lambda 2 via a semi-transmission semi-reflector. both of the two beams of light penetrate through the same part of a human body via a specimen holder to enter the photoelectric detection converter for being converted into electrical signals D1 and D2; the sugar content of the human body is obtained after the electrical signals D1 and D2 are compared and calculated with a calibration curve, and then is displayed on a liquid crystal display. The measurer has the advantages of light weight and low cost, and is capable of satisfying self-service non-wound blood sugar content measurement. The accurate rate is greater than 90%.
Description
The invention belongs to the medical electronics field, specially refer to a kind of instrument of self-service non-wound blood sugar.
Add up according to World Health Organization (WHO), the diabetes patient is to the injury of human health, become the second largest killer that the world is only second to cardiovascular disease, diabetics also will have increase by a relatively large margin in more than ten years from now on, according to investigations, to the end of this century, China's diabetics will increase to 5,000 ten thousand from 2,500 ten thousand of present statistics, annual with newly-increased 750,000 speed increase, and expand to the rural area by the city, because of labor type changes, the unreasonable factor of dietary structure and eat less moving reasons such as (mechanization raisings) more and cause the expansion of this disease and increase progressively.
Diabetes are exactly the secretory function forfeiture or the part forfeiture of human insulin, be difficult to regulate the content of self blood glucose, often under the too high situation of blood glucose, can't regulate, at this moment just need to come the content of blood sugar control by medicine, and the blood sugar for human body level is a dynamic process, preferably go to see one time the doctor weekly, at any time adjust dosage by doctor's advice, otherwise the infringement internal organs how have been obeyed, it is high again that clothes have lacked blood glucose, even cause complication, so diabetes patient's blood glucose of testing oneself every day at home of wishing to control oneself very much, and adjust dosage immediately by the result that tests oneself.Western countries have early had the domestic instrument of testing oneself, but majority all is to break the finger of controlling oneself with acupuncture, blood sample collection is seen change color on reagent paper, contrast with standard jig, draw blood glucose numerical value in the self-blood, this belongs to has the wound blood sampling to measure, and a lot of patients are unwilling to stand this pain with the pinprick finger, therefore looks forward to having the instrument that does not bear the wound misery more easily to come out.
For this reason, expected utilizing optical instrument, adopted the infrared light transdermal, detection absorbs the transmitted light intensity behind the crest, detects the method and apparatus of sugar part content in the blood.
Purpose of the present invention, be in order to overcome the method that existing need puncture the measuring blood of human body blood sample collection, to make vast diabetics or prevent the pathogenetic people of glycosuria, can relying on a photoelectric instrument at home, the AT blood sugar content in the body of testing oneself checks that disease and guidance take medicine.
The present invention relies on following technical proposals to realize, a kind of self-service non-wound blood sugar measurer, comprise the infrared light supply, light-path part, photodetection transducer, electric pathway part and the display part that constitute by the infrared light transmitting tube, light-path partly comprises the two-beam road, a branch of by reflecting mirror, pass optical filter λ 1; Another bundle sees through semi-transparent semi-reflecting lens, passes optical filter λ 2; Two-beam all passes through specimen holder and passes the same position of human body, enter the photodetection transducer, transfer signal of telecommunication D1, D2 to, circuit part comprises the enhanced amplifying circuit of the signal of telecommunication, the display part is the LCDs circuit, it is characterized in that, describedly will comprise push-pull amplifier circuit in the enhanced amplifying circuit of the signal of telecommunication, and the D1/D2 divider circuit, the wide λ=1-2.9 μ m that reaches of spectrographic operating wavelength range.
The work of this instrument is the spectrum analysis by sugar in the blood part, finds wherein and sugar part relevant absworption peak, adopts in the known blood sugar part blood sample to measure the absorption intensity of above-mentioned absworption peak as standard, sets up calibration curve and software for calculation.To compare with calibration curve by the infrared signal process that receives after the human body, and, obtain absorption intensity, and calculate the sugar content that obtains and on LCDs, show through calculating.
Specimen holder is stuck in tested human finger, ear-lobe place, and thickness is between 3-20mm between two folders.
The major advantage of this instrument, be can test oneself, easy to use, do not need to puncture finger blood sampling, need only block finger or thumb inboard or ear-lobe part with specimen holder, allow infrared ray by carrying out self-service non-wound blood sugar, and clearly blood glucose numerical value is presented on the LCD screen, AT special, eliminated the frightened phychology of Most patients, this instrument precision, accurate, through evidence, the gained data are reliable, the effective percentage height.
Further specify embodiment below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is the self-service non-wound blood sugar measurer outline drawing
Fig. 2 is this blood glucose meter structure principle chart.
Among the figure, infrared transmitting tube 1, it is 1-2.9 μ m that operating wavelength range can be selected λ, completely reflecting mirror 2 and semi-transparent semi-reflecting lens 3 are arranged in the emission light path, and correspondence is provided with λ 1 optical filter 4 and λ 2 optical filters 4 ' in this wave-length coverage, the homogeneous beam of filtering by optical cable and optical fibres 6 to infrared probe folder 5-5 ', survey transmitted light intensity by people's finger or ear-lobe again, measure the absorption intensity of sugar part correlation absorption band, optical signal converts the signal of telecommunication to by surveying transducer 7-7 ', compare and calibration curve difference afterwards through push-pull amplifier circuit 8 and the D1/D2 divider circuit 9 that the signal of telecommunication is amplified, draw the human body sugar content through computed in software machine program, be presented on the liquid crystal display screen 10 whole optical path, circuit part is installed within the portable shell 11.
Implemented successful self-service non-wound blood sugar measurer, measured human body sugar content accuracy rate greater than 90%, instrument is light, cheap.
