Description
Technical field
The present invention relates to a kind of biological body fluid or blood sample analysis device, particularly to a kind of small electrical chemical illumination immunity analysis instrument and the method for analysis thereof.
Background technology
Electrogenerated chemiluminescent immunoassay instrument is mainly used in analyte assay in clinical blood, other body fluid samples.Chemiluminescence immune assay (CLIA) is the technology worldwide grown up over nearly 20 years, relative to immuno analytical methods such as radioimmunoassay, RIA (RIA), EIA enzyme immunoassay (EIA), fluorescence immunoassays (FIA), have environmental protection, do not affected by temperature and acid-base value, reagent long shelf-life, accuracy and sensitivity advantages of higher.Therefore chemiluminescence immunoassay is widely used in in-vitro diagnosis (IVD) field.
Chemiluminescence immunoassay kind is more, such as direct chemoluminescence method based on acridinium ester, indirect chemiluminescence method based on alkali phosphatase, Electrochemiluminescince etc..Directly chemoluminescence method and enzyme touch the luminescence process of luminescent method adds exciting liquid by instrument, and therefore fluorescent lifetime is relevant to liquid addition manner.Electrochemiluminescence process fluorescent lifetime is controlled by electrode power-up time, and therefore fluorescent lifetime concordance is good.Electrochemiluminescence apparatus measures analytic unit generally uses pipeline sample introduction to design, the open input mode of relatively direct chemiluminescence, can effectively prevent open module light leak and photomultiplier tube exposes risk under ambient light.
The common instrument using Electrogenerated chemiluminescent immunoassay method has Roche cobas E411 and E601, although these instrument test speeds are fast, automaticity is higher, but take larger space, and it is unfavorable for that the occasion of less test volume uses, and these instruments belong to import equipment, expensive high with reagent test cost, therefore in small hospital, large hospital little section office Ji Shekang center cannot obtain universal use.Existing small chemical luminescence immunoassay instrument generally uses semi-automatic design, eliminates and hatches a glass feeding processing means, incubation reaction device, Magneto separate cleaning device etc., only remains luminous measurement apparatus and control system.This quasi-instrument saves instrument cost, decreases volume, but sample-adding, reagent adding, incubation reaction process are required to manual operation, add the complexity of test, and when carrying out multiple test sample at the same time, easily cause operational error, and then have impact on test result accuracy, there is potential safety hazard.Another existing fully automatic electric chemiluminescent analyzer, structure is complicated, and volume is bigger；Existing fully automatic electric chemiluminescent analyzer, carries out low-temperature preservation to reagent is typically no, it is impossible to long period placement detects；Existing fully automatic electric chemiluminescent analyzer, owing to reaction cup entirety is delivered to its measurement apparatus by needs, unavoidable need to be designed as measurement apparatus open module, so extraneous photon easily enters in measurement apparatus, when reaction cup enters measurement apparatus the most every time, form differs, when causing measuring, the faint light subnumber obtained for the photomultiplier tube PMT of reading is because being easily subject to the impact of extraneous photon entrance, causing very large deviation occur, the certainty of measurement causing whole measurement system is the highest；The most existing fully automatic electric chemiluminescent analyzer, typically no touch display unit, does not has man-machine interactive operating system, the most convenient in operation.
