Principle of work:
Urine Analyzer is by microcomputerized control, and the LED cold light source of employing different wave length is luminous, silicon photocell receives, carries out half-quantitative detection according to albedometry.Several reagent pads that contains all ingredients are arranged on the reagent band, separately with urine in corresponding composition carry out independent reaction, and show different colours.Certain becomes to be divided into specific relation in different colors and the urine.
The reagent band that is adsorbed with urine is placed on the instrument detecting carriage, the all ingredients pad that has produced chemical reaction on the reagent band is by light source irradiation, its reflected light is received by photoelectric cell, the dual wavelength light that photoelectric cell is reflected (measuring light and reference light) irradiation, and the selection of each wavelength is determined by test item.Instrument calculates reflectivity automatically by following formula, compares with tabulation then, exports the accordingly result of various compositions automatically.
Reflectance formula: R (%)=Tm.Cs/TsCm * 100%
R in the formula (%) is a reflectivity; Tm is that reagent pad is to measuring the reflection strength of wavelength; Ts is the reflection strength of reagent pad to reference wavelength; Cm is that accurate pad is to measuring the reflection strength of wavelength; Cs is the reflection strength of calibration pad to reference wavelength.

Measure wavelength: 500~700nm.
Test speed: greater than 120 parts/hour
Data storage: can store and be no less than 1000 sample data.
Reaction time: less than 60 seconds.
Printer: built-in high speed thermal printer.
The bilingual display interface of display: LCD Chinese and English.
Keyboard: membrane keyboard.
The present invention has automatic identification and whether places the reagent band and realize the function of monitoring reagent band automatically.
This external declaration be:
The main frame of this analyser comprises: the direct current generator, gear set, leading screw and the two axis of guide drive mechanism that drive the detection probe motion.Pop one's head in the motion highly stable, the good reproducibility of detection optical path length of non-jitter, instrument.Mechanical noise is small.The identification of each reagent pad color is adopted omnidistance scanning, detected the mode that uniform data is handled.Owing to adopted direct current generator, improved detection speed, greatly reduce the power consumption of instrument.Also reduced simultaneously cost.Its structural feature is: rely on nut and the screw thread on the transmission shaft on the probe to carry out transmission, make the probe can the side-to-side movement straight line.Use two parallel axis of guides, guarantee the straight motion of probe but make that vertical track of probe movement is constant, stablized the motion of probe, the homogeneity between product is criticized and the repeatability of instrument have been improved, improved the accuracy of instrument detecting greatly, reduced the requirement of other parts and the assembling difficulty of instrument.Adopt omnidistance scanning, differentiate the color GTG of each reagent pad with software intelligence.Suppress test strips effectively and put into the operate miss that detection carriage degree of depth difference is brought.
These parts comprise keyboard and the control corresponding software that only has 6 operation push-buttons and 1 power button.Under the prerequisite of handled easily, (because this instrument is very small and exquisite, total keyboard area is very little by the cursor operations instrument on the selection liquid crystal with the least possible button.It is very inconvenient that too much button can make that finger manipulation gets up).Its structural feature is: in the instrument detecting process, can be by more succinct keyboard operation (upper and lower, left and right, return, determine), finish function, the complexity that the button of avoiding too much causes, not only make outward appearance simplicity generosity more, and make operation become easier to be clear, solved too complicated problems of existing instrument people and interactive operation.
When instrument entered detected state, probe had increased for test strips whether place correct real time monitoring function.In the reaction time of the very first time instrument ability opening entry test paper that loads test strips.After detection is finished, must at first shift out intact after testing test strips, instrument just can carry out next testing process.Controlled the test paper operate miss different in the operating process effectively with the sample reaction time.Also avoided the phenomenon of same test strips duplicate detection to take place.Its method main points are: when instrument enters detected state, the placement of test strips is monitored in real time.When not having test paper, instrument is in waiting status.After loading test paper, instrument carries out timing at once.In the testing process to test paper, if the unexpected tram that breaks away from of test strips, instrument can be reported to the police automatically and be required to detect again same sample in addition.Accurately the reaction time of test paper and sample, further improved the reliability of instrument, reduced the error-detecting result that operate miss and misoperation are brought.
In the coupling part of detecting between carriage and the structure stand, designed the structure that can make things convenient for the twocouese dismounting.And increased the intelligent identifying system that automatic differentiation detects carrier direction.Its structural feature is: below detecting carriage, design unidirectional stationary wedge structure, and can two-way easily locked wedge groove in the corresponding Position Design of structure stand.The check carriage can be made personnel's the convenient, flexible change direction of left hand and right hand custom according to behaviour, reliable in action simple to operate, and parts connect and are difficult for becoming flexible; During detection, probe detects basic target automatically to determine check carriage placing direction, has made things convenient for the operating personnel of different customs, raises labour efficiency.
These parts comprise several constant current sources that are produced on above the drive plate, and they control the light emitting diode of different wave length respectively.Guaranteed because luminotron brightness is fallen or risen to the detection error of being brought.Its structural feature is: each light emitting diode all is furnished with a constant current source power supply, and after glow current was adjusted, the brightness of luminotron was constant.The light shield structure that this design fits instrument dodge gate is good makes that instrument repeated rows index in its lifetime is consistent.Also improved simultaneously accuracy of detection.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of this reality invention.
