Summary of drawings
Fig. 1 is a theory diagram of the present invention;
Fig. 2 is a structure principle chart of the present invention.
Below in conjunction with accompanying drawing 1 and testing process principle of the present invention is further described.
The dry chemical means principle: dry type urinalysis device is to grow up on the basis of the various compositions of single chemistry examination band method mensuration urine.Past is to utilize visual inspection to try colored variation, compares with on-gauge plate and draws corresponding numerical value.Dry type urinalysis device then is to utilize sphere area to analyze instrument under the control of micro computer will try to be with the light that reflects to gather on the photoelectric detector, convert electric signal to through it, again through circuit and Computer Processing measure examination with on change in color carry out the stage quantitative test.Because dry type urinalysis device is finished above-mentioned measuring process automatically, therefore can obtain than the more accurate test result of naked eyes.The test strips (band) that dry type urinalysis device is commonly used is tens of centimeter length, on the wide plastic strip of 5mm every the indicator paper block of the wide square shape of the sticking lastblock 5mm of about 2mm, the corresponding measurement index of each indicator paper block, a blank block of not participating in reaction---compensation block is as urine background color, so that caused errors such as coloured urine and instrument variation are compensated in addition on test strips in addition.During test, the test strips after the urine immersion is placed on the testing jig of instrument, makes it be subjected to the scanning of optoelectronic scanning mechanism.The photoelectric detection mechanism top is the illuminator of a strip, and the light that illuminator sends can be radiated at by the light hole up and down of surface integral on the reagent piece of test strips, and the reagent piece then can reflex to a part of light in the integrating sphere.Because reagent piece color look and depth difference, the light intensity of its reflection is also different.For example, the content of certain chemical constitution is lower in the urine, and the color relation of its reagent corresponding piece is more shallow, the light intensity that it reflects; Otherwise, if content is higher, then Fan She light intensity a little less than.
The surface integral instrument has the effect of converging ray, the light that is reflected on the reagent piece is assembled the back by the surface integral instrument and is shone on the photoelectric detector by optical filter, photoelectric detector is converted to electric signal with light signal, electric signal send one to microprocessor system through amplifier and digital-to-analog conversion, microprocessor is obtained the reflectivity of the reflectivity of every kind of tested reagent piece and compensation block and is compared with the curve that exists reflectivity in the microcomputer and expression to analyze constituent concentration in advance, at last by semiquantitative grade symbol of printer output and concentration value.
The depth of reagent piece color is except that the difference with each tested composition and content becomes, and is also relevant with the color of urine itself.For eliminating this error, on test strips, be provided with blank block (compensation block), though it with tested composition change color does not take place, with the change color of urine.
Dry type urinalysis device adopts dual wavelength (by a branch of mensuration and a branch of reference light of optical filter) determination method at present.Instrument can calculate reflectivity R automatically by following formula.
The reflectivity of test paper
R test paper=Tm (reagent is to measuring the reflection strength of wavelength)/TS (reagent is to the reflection strength of reference wavelength) * 100%
Blank reflectivity
R blank=Cm (blank)/CS (blank reflection strength) * 100% to reference wavelength to measuring the reflection strength of wavelength
Total reflectivity R
R=R test paper/R blank=Tm CS/TS Cm * 100%
The fluidic cell principle of work: Flow Cytometry comprises liquid fluid system, optical system and electronic system.Cell in the sample to be tested transmits the zone of passing through laser radiation in the stream type cell device in order through liquid fluid system, the cell Stimulated Light excite the generation signal, accepted by signal receiver and amplify, these signals that amplified are the machine analyzing and processing as calculated, and shows intuitively with the form of chart; The signal that stream type cell device produces and analyzes mainly contains light scattering signal and fluorescent signal.The power of light scattering signal can reflect the degree etc. of size, form and the cytoplasmic granuleization of cell.According to the difference of luciferin, with the optical excitation of different wave length, launch the fluorescent of different wave length, can show different colors, these fluorescent signals just can reflect different characteristics of cell biology.
To make single cell suspension behind the cell dyeing to be measured.With certain pressure testing sample is pressed into flow chamber, not celliferous level pad under high pressure sprays from the sheath fluid pipe, sheath fluid tube inlet direction and testing sample stream are angled, like this, sheath fluid just can hold the sample flow at high speed, the a fluid stream of forming a circle, cell to be measured single file under the bag quilt of sheath fluid is arranged, successively by laser irradiation area (laser beam of fluid column and incident intersects vertically and a little is called detection zone), be subjected to send fluorescent of all kinds after the strong laser radiation by the cell of fluorescence staining, produce light scattering simultaneously.The collection of fluorescent signal can be placed optical system (lens, Guang Lan and filter disc etc.) in order to collect the fluorescent signal in 90 vertical degree directions of laser beam, invests detecting device.The fluorescent detecting device is a photomultiplier, and light scattering detector is a photodiode, is used for collecting forward angle light scatter light.Light scattering signal is surveyed deeply at the little angle of forward direction (2-10 degree), and this measurement claims " forward angle light scatter " or " forward scattering ".The light scattering signal of Chan Shenging has reflected the size of cell volume basically in this case.Fluorescent photomultiplier and forward light electric diode that fluorescent signal that cell sends and light scattering signal are an angle of 90 degrees direction simultaneously receive, be converted to electronic signal input multiple tracks (1024 road) pulse analysis device after being exaggerated integration, and on computer screen, show with one dimension histogram, two-dimensional bitmap or three-dimensional picture.Or figure and data directly imported the computing machine of online special use, or deposit disk in order to analyzing.Computing machine is surveyed data computation with institute fast and accurately and is come out, and in conjunction with multi parameter analysis, thereby has realized cell quantitative.
