Description

Device for detecting deposit dregs in urine

Technical field

The utility model discloses a kind of Medical Devices, specifically is the device of clinically arena being implemented detection.

Background technology

Urinalysis is estimated antidiastole, observation of curative effect, the prognosis of diseases such as urinary system, cardiovascular system, endocrine system, liver and gall road, poisoning clinically and the value of drug test, healthy preliminary assessment is affirmed by medical circle already, be described as " biopsy of painless property kidney " and be widely used in clinically, classified the routine inspection project at present as.For a long time, because of the urine complicated component, disturbing factor is many, it is lack of standardization to draw materials, transport, handle, and lacks standardized instrument and Quality Control means, often influences accuracy and clinical value as a result.In recent years, Urine Analyzer comes out and the increase of arena quantitative detecting method, though improve detection speed, sensitivity and accuracy as a result greatly, but still fail fundamentally to solve the urinalysis standardization issue.

From the manual examination of urinary sediment method of routine, urine method of uropsammus examination mixing is easy but lack of standardization, positive rate is low at present; The centrifuge method sensitivity detects the positive rate height, and this is owned by France in the conventional sense method of present suggestion, but needs standardization.Help the normal and poikilocyte of identification with the phase microscope method.Make hyalina be difficult for omission with decoration method, also help the observation of various cell component structures.Can adopt the various compositions in the new technology identification arenas such as histochemistry, immunochemistry, fluorescent dye in case of necessity, also can contrast to improve the recognition capability of the various compositions of arena with the dry chemical check result.

At present uropsammus examination is the most frequently used remains pattern hand-manipulated, traditional slide and plastics smear method had both consumed manpower, there is the difference between the operating personnel again, and the restriction of condition, can flow to cover glass edge, viscous sample occasionally as arena, thickness is difficult to hold, and this maintenance to accuracy, repeatability, standardized operation bring difficulty.

Along with Chinese clinical examination standard subcommittee (CCCLS) and U.S. clinical examination standard committee (NCCLS) integrate with, China has formulated the urinalysis levels of standards, and the exploitation of standardized automatic urinary sediment check and analysis system and device has been the task of top priority.

Technology contents

But the purpose of this utility model provides a kind of device for detecting deposit dregs in urine of execution standardization flow operations.

For achieving the above object, this device has adopted following technical scheme: device for detecting deposit dregs in urine, it is characterized in that: pick-up unit comprise one drive by drive unit and keep place the rotating disk of cleaning fluid, dyeing liquor and urine sample and one around vertical to the rotating shaft that is provided with being used to of rotating can be from the sampling probe of extracting liq sample on the rotating disk, sampling probe is connected on the input end of operation valve by pipe fitting, the output terminal of operation valve is connected on the input end in numeration pond, and the output terminal in numeration pond is received the waste liquid recover through peristaltic pump.

The utility model can be finished the quantitative absorption of sample and dyeing liquor, dyed blended a series of canonic orderings fast and automatically in conjunction with computer control, comprise therebetween the doubly amount dilution automatically of high density sample, with mix, sample delivery after the dyeing is to optics urine sediment quantitative analysis plate, by the microscope image pick-up device, the operator can obtain arena image clearly on the microscope screen.Tangible part in the arena is carried out qualitative, quantitative test, in conjunction with urinating the data that the dry analysis instrument transmits, comprehensive other diagnosis and treatment information of patient, the check doctor can propose diagnostic comments, exports true color urinalysis picture and text report by computing machine with standard format at last.
