Abstract
The method includes steps: putting test tube having urine to be tested to sucking position in analyzer. The analyzer sucks the urine into stock solution storage chamber automatically. Microporous membrane concentration unit is installed behind the solution storage chamber. Pressure is applied to the solution storage chamber and vacuumizing is carried on other side of filter membrane. Thus, the urine is concentrated. When concentration ratio reaches specification, the urine is transferred to counting cell/slide under microscope automatically. Under control of scanning platform, images of counting cell at different position are collected. Based on anhydration analysis and image collected, the analyzer gives result. The method simplifies steps operated by doctor.

Technical field
The invention belongs to technical field of medical detection, be specifically related to a kind of urine sediment analysis methods concentrated, check and analysis that integrate.
Background technology
The urine sediment analysis method is divided into two classes at present: the first kind is to utilize the morphology inspection side method of light microscopic, and advantage is can detect and accurate all visible components of differentiating in the urine, is confirmatory test to urine sediment analysis, and the checkout equipment valency is low.The step of this method is as follows: the test tube that 1, urine to be detected will be housed is earlier put into hydro-extractor, 2, opened hydro-extractor centrifugal 5 minutes, 3, the test tube level is toppled over fall supernatant liquor, again test tube is placed on the suction sample station of urine sediments analyzer, 4, instrument adds urine sample in microscopically counting chamber or the tally, moves micro-platform, finishes the image acquisition of regulation area, 5, last doctor draws testing result according to the visible component in the image discriminating urine of gathering.Wherein employed urine sediments analyzer is existing matured product.By the said method step as seen, this method shortcoming is the step that exists many doctors of needs to operate in implementation procedure, causes the analytical instrument automaticity low, influences detection speed, and doctor's workload is many.The second alanysis method is to utilize Flow Cytometry and impedance bioelectrical measurement method, this method can detect red blood cell, leucocyte, epithelial cell, cast bacterium, speed is fast, but can not detect all visible components, the true picture of urine slag can not be provided, just scatter diagram, to urine sediment analysis, not confirmatory test, can only sieve, equipment valency height.
Examine the advantage of side method for the morphology that makes full use of light microscopic, the development automaticity can be compared with the instrument of impedance bioelectrical measurement method with utilizing Flow Cytometry, above-mentioned doctor manual operation section must be removed as far as possible,, increase the reliability that detects to improve detection speed.Several steps above analyzing, find the step that most importantly speed that influences concentrate with hydro-extractor, owing to be difficult for the hydro-extractor and the existing urine sediments analyzer that run up is integrated, cause this step to operate by the doctor separately, a urine sample concentrates and needs at least more than 5 minutes, and can not many parts of urine samples concentrate simultaneously, directly cause detection speed to be difficult to improve.Therefore, the method that must seek new concentrated urine substitutes hydro-extractor and reaches the concentrated urine purpose, does not destroy the composition that arena detects again, and easy and integrated speed and the robotization that improves urine sediment analysis of urine sediments analyzer.
Summary of the invention
The present invention is directed to the above-mentioned shortcoming that existing urine sedimentation detecting method exists, by liquid concentration analysis of technology with present maturation, the inventor has proposed a kind of urine sediment analysis methods concentrated, check and analysis that integrate, should come concentrated urine by miillpore filter, substitute the concentration step in the former method,, this step directly can be realized on instrument by the miillpore filter technology of maturation, reach and simplify doctor's operating performance, improve the purpose of detection speed and reliability.
A kind ofly integrate urine sediment analysis methods concentrated, check and analysis, the entire method step is as follows:
1. the test tube that urine to be detected will be housed is earlier put into the suction sample station of urine sediments analyzer.This step is different from the step of existing method, and existing method needs use the hydro-extractor concentrated urine earlier by the doctor in addition, outwell supernatant liquor after, the urine after will concentrating is again put into the suction sample station of urine sediments analyzer.
2. the suction needle of urine sediments analyzer sucks invisible spectro urine in the fluid storage compartment automatically, can finish the dyeing function to fluid storage compartment adding dye liquor by dye liquor application of sample mouth according to detecting needs.
3. be connected with the miillpore filter enrichment facility behind the fluid storage compartment, vacuumize by urine in fluid storage compartment pressurization with at the filter membrane another side of miillpore filter enrichment facility, urine is under differential pressure action, small-molecule substances such as moisture pass filter membrane and take out, the visible component that arena need detect is left and concentrates, behind the cocnentration factor that reaches regulation, urine is transferred in microscopically counting chamber/plate automatically.This step also is different from the step of existing method, existing method is directly transferred to concentrated urine in the counting chamber, or dyeing earlier, after the dilution concentrated urine is transferred in the counting chamber, it concentrates is not to finish in analytical instrument, but is gone to finish by doctor's manual operations with hydro-extractor in addition.
4, under the scanning platform control of analyser, automatically gather counting chamber diverse location image, analyser draws analysis result for check doctor reference according to the arena image of mummification analysis result and collection, and the check doctor confirms to import behind the corresponding information with regard to printable report.This step is identical with the step of existing method.
In the step 2, the pore size of filter membrane is to select suitable aperture for use according to the size of minimum visible component in the visible component to be measured in the urine.
This shows, this method is compared with existing method, it comes concentrated urine by miillpore filter, the principle of utilizing miillpore filter the composition greater than the filter membrane aperture in the liquid can be separated, adopt pressurization and vacuum filtration that small-molecule substances such as the moisture in the urine, salt are gone out, the film below stays the concentrated urine that contains whole visible components to be measured in the urine, reached the purpose of concentrated urine like this, substitute the concentration step that separates with analyser in the former method, to concentrate, check and analysis have combined in one, thereby have improved detection speed.And filtering with microporous membrane is ripe liquid concentration technology, it is close that it and human kidney produce urine, it is very little to the destruction that arena detects composition, be easy to the integrated urine sediments analyzer that advances, and it can make hyperchannel miillpore filter enrichment facility, can finish many parts of urines simultaneously manages outward, the test tube that the doctor only needs patient's urine will be housed is put into suction sample station, negative sample get final product after 2 minutes the result, exceptional sample adds that the doctor differentiates that the time manages outward, every patient can not surpass 4 minutes from sending urine sample here to reporting, and the doctor is simple to operate, and speed is fast.
