Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, is the structural representation of the blood cell analysis chip of the embodiment of the present invention.The blood cell analysis chip of the embodiment of the present invention comprises leucocyte/hemoglobin analysis chip and red blood cell/blood platelet analysis chip.
Described leucocyte/hemoglobin analysis chip comprises: four hive off cell analysis chip and basophilic granulocyte analysis chips.Refer to Fig. 2, Fig. 2 has disclosed four structural representations that hive off the cell analysis chip of the blood cell analysis chip of the embodiment of the present invention.Four hive off on the cell analysis chip is provided with liquid storage tank, waste liquid pool, detection zone, colorimetric pool and quantitative assembly.Described liquid storage tank is for the storage of blood sample and detect reagent; Described waste liquid pool is for storing the blood sample through detecting; Described detection zone carries out the electrical impedance detection while for the leucocyte that makes blood sample, passing through detection zone and optical absorption method detects, and by absorptance and cell size difference, the blood sample detected is classified; Described colorimetric pool is for detection of the concentration of haemoglobin; Described quantitative assembly is for making the interior corresponding fluids of each liquid storage tank quantitative.In embodiments of the present invention, liquid storage tank arranges at least one, when carrying out white blood cell count(WBC), anticoagulation (being the most frequently used in visiting work and one of most important anti-coagulants and reagent) sample introduction is to the A1 liquid storage tank, coloring agent (contains hemolytic agent and dyestuff, 100-150mOsm/kg or 800-1500mOsm/kg, the solution that pH is 2-8) sample introduction is to the A2 liquid storage tank, makes anticoagulation and coloring agent flow out and realize mixing from liquid storage tank separately.The effect of this process is: 1. blood carries out the haemolysis processing to destroy the RBC/PLT/BASO cell, and fragment is much smaller than leucocyte; 2. the special particle of monocytic primary granule, eosinophil and neutrophil leucocyte carried out to dyeing in various degree, the film (cell membrane, nuclear membrane, membrana granulosa) of cell is also carried out in various degree painted simultaneously; 3. the form of fixed cell, make it keep state of nature.The sheath fluid sample introduction is to the B1 liquid storage tank, and dyed quantitative blood sample is under quantitative sheath fluid effect, and leucocyte is in line and, one by one by the narrow structures (upper and lower two ends apply steady current) of detection zone S1 middle and lower reaches, detects and the inflow downstream through electrical impedance.The electrolytic solution oozed than grade due to the conductive properties of haemocyte is low, when haemocyte passes through narrow structures, narrow structures place voltage changes, the signal receiver of corresponding electrical impedance technology setting will receive a pulse signal, the size of this pulse signal depends on the blood cell volume size by narrow structures, the number of pulse signal depends on by the haemocyte of narrow structures how many, thereby how many and size obtains the cell volume measurement result according to pulse signal.Because lymphocyte, monocyte, neutrophil leucocyte and eosinophil are different to the coloring degree of coloring agent, the structure of every kind of specific karyomorphism of cell and particle causes the intensity of light scattering different, produced specific absorptance, carry out the absorptivity analysis at the narrow structures place with situations such as judgement cellular morphology and contents, raji cell assay Raji information shows in the relevant position of scatter diagram the most at last simultaneously.The characteristic showed on these two analytical parameters according to every class cell, the scatter diagram of formation Two dimensional Distribution.Can complete leucocyte medium size lymphocyte, monocyte, neutrophil leucocyte and acidophil group's classification in this detection zone.Simultaneously, RBC(Red Blood Cell, red blood cell count(RBC), refer to mean constant of red blood cell contained in unit volume blood) in destroyed, discharge haemoglobin, haemoglobin and hemolytic agent (haemoglobin detected components and erythrocyte hemolysis agent, hemolytic agent is hypotonic, acid, the solution that contains appropriate wetting agent, red blood cell in the rapid dissolved destruction blood of energy, discharge haemoglobin and form with it stable compound) reaction formation haemoglobin dervative, enter the haemoglobin test macro, be colorimetric pool E, and under the specific wavelength of 530-550nm colorimetric, in the variation of absorbance and liquid, the content of haemoglobin is proportional, can record the concentration of haemoglobin thus.
Refer to Fig. 2, Fig. 2 has disclosed the structural representation of basophilic granulocyte analysis chip of the blood cell analysis chip of the embodiment of the present invention.Be provided with liquid storage tank, waste liquid pool, detection zone and quantitative assembly on the basophilic granulocyte analysis chip of the embodiment of the present invention.Liquid storage tank is for the storage of blood sample and detect reagent, and waste liquid pool is for storing the blood sample through detecting, and detection zone is for calculating the Effective Numerical of leucocyte bare nucleus and basophilic granulocyte.Wherein, liquid storage tank quantity is at least one, is respectively used to store anticoagulation, basophilic granulocyte dilution and sheath fluid.In embodiment of the present invention, the detailed process that the basophilic granulocyte analysis chip is detected is: the anticoagulation sample introduction is to the A1 liquid storage tank, basophilic granulocyte dilution (hemolytic agent, 100-150mOsm/kg or 800-1500mOsm/kg, the solution that pH is 2-8) sample introduction is to the A3 liquid storage tank, quantitatively anticoagulation and quantitatively hemolytic agent flow out and realize mixing from liquid storage tank separately, lysed erythrocyte, because basophilic granulocyte has resistance to acid, can keep complete form, and other leucocyte endochylemas overflow, become the bare nucleus state.The sheath fluid sample introduction is to the B2 liquid storage tank, treated blood sample is under quantitative sheath fluid effect, leucocyte in blood is in line and the aperture by detection zone S2 middle and lower reaches (upper and lower two ends apply steady current) one by one, detect (being that each cell results from the proportional electronic impulse of cell volume) and flow into waste liquid pool W2 through electrical impedance, take the cell volume size as horizontal ordinate drafting WBC/BASO histogram.Through the signal processing system Treatment Analysis, distinguish leucocyte bare nucleus and basophilic granulocyte according to Threshold, provide total white blood cells and basophilic granulocyte Effective Numerical more accurately.In embodiment of the present invention, the basophilic granulocyte analysis chip adopts biological dissolution technology and electrical impedance technology to detect basophilic granulocyte, further improves and detects performance.
In Fig. 2, quantitatively assembly F1 to F8 is for making in each liquid storage tank corresponding fluids quantitative.
