The hollow-core fiber is disposed in a support seat chute by pressing the gland onto the slider, the electromagnet is fixed at a core head of the upper head of the support seat while screwing down the gland, the casing of the photomultiplier tube is installed at steps inside the sleeve, a photocathode of the photomultiplier tube is aligned to the optical fiber, and the optical fiber or the light guide stick is hollow-cored. For measurement with the utility model, the hollow-core silica fiber is driven by the electromagnet to move to seal optical signals, and a measured weak optical signal passes through the hollow-core silica fiber of high light guiding and is directly transmitted to the photocathode of the photomultiplier tube, thereby effectively shielding interference from the adjacent wells and external light, and increasing the measuring precision and sensitivity. An intermediate hollow core of the hollow-core silica fiber is used for equipping with an automatic liquid charging pipeline, thereby increasing the measuring precision and liquid charging accuracy for flash-type reagent, and further the utility model has the advantages of reasonable structure and simple processing, and is easy for batch production.
Description
Technical field
The utility model relates to the faint light of using on a kind of chemical illumination immunity analysis instrument and detects countermeasure set between shield opening.
Background technology
Chemical illumination immunity analysis instrument is a kind of medical testing equipment that carries out the human immunity analysis by the patients serum, chemiluminescent immunoassay(CLIA) (CLIA) is a kind of extremely sensitive microdetermination technology, is applicable to the quantitative test of micro substance in the multiple bodies such as thyroid hormones, gonadal hormone class, tumor markers class and hepatitis, acquired immune deficiency syndrome (AIDS).Quantitative patients serum and enzyme labeling thing are joined solid phase to be had in the enzyme mark batten of White-opalescent of antibody, testing molecule in the serum and enzyme labeling thing emulative with solid phase on antibodies.The unconjugated free composition of separating, washing adds the luminous substrate working fluid, and enzymatic makes luminous substrate luminous.Mark batten with enzyme and insert in the analyser this moment, read the luminous value in each hole successively by Photo Counting System.During the photon number of single photon counter each hole cup in measuring batten, can be subjected to the influence of the photon of adjacent bores on every side, thereby the influence amount of measuring result is called for short: disturb between the hole.So just influenced measuring accuracy and sensitivity, be directed at and obtain fine data.This kind influence is a chemical illumination immunity analysis instrument measuring accuracy disadvantage on the low side.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of faint light that can improve the chemical illumination immunity analysis instrument measuring accuracy to detect countermeasure set between shield opening.
The purpose of this utility model is achieved through the following technical solutions.
A kind of faint light detects countermeasure set between shield opening, comprises that electromagnet, supporting seat loam cake, optical fiber gland, slide block, supporting seat lower cover, optical fiber or lamp guide, Rubber end, photomultiplier, sleeve, photomultiplier pipe box and supporting seat etc. partly form.Optical fiber is pressed in the chute of putting into supporting seat on the slide block by the optical fiber gland, the upper and lower covers of supporting seat is fixed in the position up and down of supporting seat, electromagnet is fixed on the core print place of supporting seat loam cake, be screwed in the optical fiber gland, the photomultiplier pipe box step place in the sleeve of packing into, sleeve is screwed into the photomultiplier of supporting seat, the sleeve of packing into, the photocathode of photomultiplier and fiber alignment.The middle part of this optical fiber or lamp guide is a hollow.
The utility model drives the motion of hollow silica fibre by electromagnet, will be airtight firmly when measuring by light signal, tested faint optical signal directly imports the photocathode of photomultiplier into by the hollow silica fibre of high light-conductive rate, thereby effectively shield the interference of adjacent bores and extraneous spatial light, improve measuring accuracy and sensitivity.Hollow is used to install automatic liquid feeding pipeline in the middle part of the hollow silica fibre, improves flash type reagent measuring accuracy and liquid feeding precision, and the utility model apparatus structure is reasonable, processing is simple, be easy to batch process.
