Description
A kind of analyser reagent of the present invention particularly relates to a kind of blood analysis instrument dilution and preparation method thereof.
The K-4500 blood analyser is the another new product in the K of the company product of Japanese East Asia, is a kind of full-automatic multi parameter analysis instrument, and 18 parameters (three classification), three kinds of cell particle size distribution figures can be provided.Welcome by the demestic user.But its consumables equal dependence on import, particularly dilution, the routine work requirement is big, and import price is very expensive, and application cost is very high.
The blood analysis instrument dilution that the purpose of this invention is to provide a kind of autogamy, it and import reagent there was no significant difference on measurement result is a kind of production domesticization reagent of effect excellence.
Another object of the present invention provides a kind of preparation method of blood analysis instrument dilution of above-mentioned autogamy.

2O, EDTA-2Na, Kcl and chlorhexidine acetate, dual distilled water after the Hybrid Heating 50-60 ℃ of dissolving, are that the fabric ester micro-hole filtering film circulating filtration of 0.2 μ m was emitted and got final product in 30-60 minute through enclosed filter device, aperture.
Wherein said enclosed filter device is that 150mm, aperture are that the fabric ester micro-hole filtering film of 0.2 μ m, corresponding stainless-steel tube, valve are formed by stainless steel liquid mixer 100L, medical preparation pump 1100W, the 5 layers of diameter membrane filter that is 150mm and 10 diameters.
Can also be included among this preparation method emit after, the PH that measures reagent is 7.6 ± 0.05, osmotic pressure is 282 ± 2mosm/L, go up machine debugging background multiparameter all meets the requirements, and can use.
By contrast test, blood analysis instrument dilution of the present invention and import reagent are compared:
1, the contrast test of autogamy reagent and import reagent and correlativity: 41 of picked at random inpatients, the 1-2ml that phlebotomizes injects and contains in the import anti-freezing bottle of EDTA-2K, abundant mixing, after placing room temperature (25 ℃ of optimum temperatures) 30min, detect with autogamy reagent and import reagent respectively, want abundant mixing to finish in the 2h after blood sampling before each test, the results are shown in Table 1, unit is legal unit.
2, repeatability is measured: get 1 part of anticoagulation, respectively measure 20 times with autogamy reagent and import reagent respectively, the results are shown in Table the result of 2,15 parameters there are no significant difference, P (2)＞0.05.
3, contrast test gained WBC, RBC, three cell particle size distribution figures of PLT overlap the degree height, mostly are fully to overlap.
The contained various chemical constitutions of contrast, repeatability, correlativity, histogram repeatability and dilution by above clinical practice and test findings are all harmless etc. to measuring system, the piping system of instrument, as can be known the complete alternative K-4500 import dilution of autogamy reagent.
Adopting enclosed filter device via hole diameter among the preparation method of blood analysis instrument dilution of the present invention is that the fabric ester micro-hole filtering film of 0.2 μ m was through 30-60 minute circulating filtration, not only remove particulate, but also degerming, reagent background parameter is in full accord with import reagent; Because cellulose esters has any biological inert, has the not characteristic of adsorption charge, can prevent the consumption of ion, so the effect of filtering through its device is better than filtering through G6 glass bacteria filter, more be adapted to produce in batches, and equipment investment is few, production technology is simple, is easy to promote.
The made blood analysis instrument dilution prescription of the present invention advantages of simple, expense is low, and is solution-stabilized, and room temperature can be preserved 4-6 month, can substitute import dilution, economic benefit and obvious social benefit fully.
Further describe the present invention below in conjunction with embodiment and accompanying drawing:
