Hemolyzing reagent and blood to be detected are injected in mixing chamber 2 from the first peristome, rocks and make both mix, so Afterwards integration member 1 being arranged on analyser by fixed structure, light source module emits beam and is irradiated mixing position, chamber 2, And the photoanalysis module of opposite side is to detecting via the light after mixing chamber 2, and by corresponding photosignal transmission Analyze module to blood parameters to get corresponding results, final display module 15 shows.

Erythrocyte in the inner cell suspension of mixing chamber 2 is dissolved into fragment by hemolyzing reagent, discharges hemoglobin, the most molten Other composition in blood reagent reacts with hemoglobin, generates coloring matter, and content of hemoglobin is the highest, the color of liquid The deepest, light transmission the poorest (or light absorptive is the strongest).Generally, discharge hemoglobin, be combined formation cyaniding with hemolyzing reagent Hemoglobin (having cyanogen hemolyzing reagent) or particular complex (without cyanogen hemolyzing reagent).The way of detection light transmission is usually so , using the light source on corollary new blood analyser 11, this light source is typically with the monochromatic light of wavelength 525nm, and light is saturating (meaning of window is the district that wall ratio mixing other position, chamber 2 is thinner to cross the hemoglobin detection window on mixing chamber 2 Territory, more conducively transmitted light, such wall thickness is proper between 0.5 millimeter to 2 millimeter, can use more transparent simultaneously Material, the light transmittance of material preferably more than 90% and homogeneous, stability of characteristics), and at the opposite side in mixing chamber 2, use Photoelectric device detection transmitted intensity on corollary new blood analyser 11, and compared with the Hemoglobin Value calibrated, i.e. Content of hemoglobin can be drawn.

Ordinary circumstance, in order to reduce each disposable blood cell counting and the material transmittance of analytic set member 1, haemolysis The transmittance of reagent, the sensor random error that the trickle difference of placement location is brought in analyser, hemolyzing reagent can be by elder generation Inject mixing chamber 2, when reagent is already at resting state, can first detect transmitted intensity the most at this moment, as background values, Namely blank through light intensity, by this blank light intensity that passes through divided by the transmitted intensity having hemoglobin recorded afterwards, then Compared with the Hemoglobin Value calibrated, content of hemoglobin more accurately can be drawn.The most conventional light path system In order to prevent light scattering and ambient light interference, double-wavelength method can be used to measure.

Drawn by light source module and photoanalysis module is the parameter of hemoglobin in blood, and this is in hemanalysis Modal parameter value.The principle of existing blood analyser detection hemoglobin is identical with this programme, is all to use optical telecommunications Number analysis method, but it needs to utilize internal liquid-way system to be sucked by blood to be detected, adds reagent again in inside mixed Even, then utilize photoanalysis module that blood carries out detect analysis and draw hemoglobin parameters, terminate to need afterwards in analysis Whole liquid-way system is cleaned for detecting by the cleaning procedure started in instrument next time.And integrated in this programme Part 1 utilizes mixing chamber 2 to instead of the liquid-way system in original instrument, and analyzing integration member 1 after detection terminates can abandon, and saves Loaded down with trivial details cleaning procedure, also greatly simplified the structure of original blood analyser.
