Above-mentioned leucocyte detecting device 41 mainly is made of fluorescence detector, particularly, is made of the detecting device that uses flow cytometry.At this, so-called cell art is promptly measured physical property and the chemical property that cell and other biological are learned particle, and so-called flow cytometry refers to: allow these particles from thread by, carry out method for measuring.Figure 4 shows that the optical system of leucocyte detecting device 41.In the figure, the light beam that penetrates from lasing fluorescence diode 401 shines haemocyte in the sheath flow pool 403 of flowing through by collimating mirror 402.This leucocyte detecting device 41 detects forward scattering light intensity, lateral scattering light intensity and the side direction fluorescence intensity that the haemocytes in sheath flow pools 403 are sent under laser radiation, with this as the haemocyte characteristic parameter.
At this, scattering of light is because this particle of haemocyte becomes barrier on the direct of travel of light, the phenomenon that light therefore changes its direct of travel and produced.Detect the particle characteristics information that this scattered light can obtain relevant particle size and composition.Forward scattering only refer to particle that send with the essentially identical scattered light of direct of travel institute's irradiation light.Can obtain the characteristic information of relevant particle (haemocyte) size from the forward direction scattered light.Lateral scattering only particle send with institute irradiation light scattered light slightly in vertical direction.Can obtain the characteristic information of relevant particle inside from side scattered light.When laser radiation was to the haemocyte particle, the lateral scattering light intensity depended on the complicacy (quantity of the shape of nuclear, size, density and particle) of cell interior.Therefore, utilize this characteristic of lateral scattering light intensity (discriminating) haemocyte of can classifying, and measure haemocyte quantity.In addition, stated present embodiment and taked to use forward scattering light and side scattered light structure as scattered light, but be not limited thereto, so long as can obtain to analyze the scattered light signal of needed reflection particle characteristics, scattered light is not limit through the angle of the optical axis of the light of sheath flow pool irradiation for light source.
Illumination is then sent than the longer light of institute's irradiation wave-wave such as the sort of fluorescent material of dyed haemocyte.Fluorescence intensity is to dye good more by force more, measures the characteristic information that this fluorescence intensity just can obtain relevant blood cell staining degree.Therefore, poor according to (side direction) fluorescence intensity can be to leucocyte mensuration such as classify.
As shown in Figure 4, the forward scattering light that the haemocyte (leucocyte and erythroblast) of sheath flow pool 403 sends of flowing through is accepted by light emitting diode (forward scattering light optical collector) 406 by condenser 404 and pin hole 405.Side scattered light is accepted by photomultiplier (side scattered light optical collector) 411 by condenser 407, dichronic mirror 408, blooming 409 and pin hole 410.Side direction fluorescence is accepted by photomultiplier (side direction fluorescence optical collector) 412 by condenser 407 and dichronic mirror 408.From the suffered light signals of each optical collector 406,411 and 412 outputs amplify by the analogue signal processor 5 that constitutes by amplifier 51,52,53 etc. respectively and analog signal processing such as waveform processing after, be transported to microcomputer 6.
Below, describe with regard to the structure of RBC/PLT detecting device 42.Fig. 5 is the brief configuration mode chart of RBC/PLT detecting device 42.RBC/PLT detecting device 42 can use sheath stream DC detection method to measure RBC number and platelet count.RBC/PLT detecting device 42 has sheath flow pool 42a as shown in Figure 5.This sheath flow pool 42a is provided with the application of sample mouth 42b of upward opening, and sample can add this application of sample mouth 42b from reaction warehouse 17.The sheath flow pool 42a tapered taper sample storehouse 42c that makes progress in addition, above-mentioned application of sample mouth 42b just is configured in the central interior of this sample storehouse 42c.42c upper end in sample storehouse is provided with hole 42d, and this hole 42d is just in time relative with application of sample mouth 42b center.The mensuration sample that confession sample device provides upwards transports from the front end of application of sample mouth 42b, and meanwhile, preceding sheath fluid is fed to sample storehouse 42c, and preceding sheath fluid upwards flows to hole 42d.At this, measure the encirclement current downflow of sample at preceding sheath fluid, taper sample storehouse 42c attenuates the mensuration sample stream, and the haemocyte of measuring in the sample passes through hole 42d one by one.Hole 42d establishes electrode, supplies to have DC current between this electrode.Detect the variation of the direct current resistance of hole 42d when measuring sample stream via hole 42d, this electric signal is outputed to controller 25.Above-mentioned direct current resistance can increase during by hole 42d at haemocyte, and therefore, this electric signal reflection haemocyte is by the information of hole 42d, by this electric signal is carried out signal Processing, to red blood cell and platelet count.
The top of hole 42d is provided with the recovery tube 42e that extends up and down.This recovery tube 42e is disposed at by in hole 42d and the sample storehouse 42f that sample storehouse 42c links to each other.Separate with sample storehouse 42f inwall recovery tube 42e lower end.Sample storehouse 42f has back sheath fluid to provide, and after this sheath fluid flows downward along the exterior lateral area of the recovery tube 42e of sample storehouse 42f.After the back sheath fluid that flows through from the recovery tube 42e outside arrives 42f lower end, sample storehouse, between the inwall by recovery tube 42e lower end and sample storehouse 42f, flow to recovery tube 42e inside.Therefore can prevent to reflux, thereby prevent the flase drop of haemocyte by the haemocyte of hole 42d.

Microcomputer 6 has the A/D converter 61 that the analog signal conversion that analogue signal processor 5 is provided is a digital signal.The output valve of A/D converter 61 is transported to the exerciser 62 of microcomputer 6, performs calculations at exerciser 62, and the light harvesting signal is carried out certain processing.Exerciser 62 is made distributed data (two-dimentional scatter diagram (unfiled) and one dimension histogram) according to the output valve of test section 4.
Microcomputer 6 comprises the controller 63 that is made of with storer with processor operation with processor and control control and moves the data analysis unit 64 that the storer of usefulness constitutes by analyzing with processor and analysis with processor.Controller 63 is used to control instrument mechanical part 8 and other parts formed for the fluid system of sample device (diagram is omitted), sample preparation and mensuration usefulness etc. by automatic supply heparin tube.Data analysis unit 64 is used for that each distributed data is carried out examination etc. and analyzes and handle.Analysis result is transported to outside data processing equipment 3 by interface 65, carries out processing such as video data picture and storage data.
Microcomputer 6 has interface 66 that is connected with display operation part 7 and the interface 67 that is connected with device for mechanical part 8.Exerciser 62, controller 63 and interface 66,67 are connected by bus 68, and controller 63 is connected by bus 69 with data analysis unit 64.Comprise on the display operation part 7 that operating personnel assign beginning switch and display instrument state, various setting value and the analysis result that begins to measure indication, the touch-screen type LCD of accepting operating personnel's input.
Operation with regard to the cellanalyzer 1 of present embodiment describes below.Fig. 7 is the process flow diagram of the sample analyzer operation of present embodiment.User (operating personnel) connects the power supply (step S1) of cellanalyzer 1, starts cellanalyzer 1.This cellanalyzer 1 carries out self check (step S2) earlier when starting.In self check, not only test the ruuning situation of respectively moving mechanical part of microcomputer 6, inspection cellanalyzer 1, the blank of also measuring the blank sample that does not contain sample detects.Then, 6 pairs of mode determinations of microcomputer carry out initial setting (step S3).This initial set value is the CBC+DIFF pattern.Particularly, in the processing of step S3, set to measure the parameter (service condition) of blood, as used reaction warehouse and minute setting etc.So, the sample analyzer of present embodiment is the initial launch pattern with the blood measuring pattern.In view of the above, cellanalyzer 1 is in and can accepts the holding state that begins to measure.The picture (step S4) of microcomputer 6 display notification holding state on LCD.
Under this holding state, operating personnel can be switched mode determination by operation display operation part 7.Fig. 8 is for setting the input image mode figure of mode determination.There are mark this shop 120, sample to put into schema category 121, subitem detection (mode determination) kind 122 and species of samples 123 each display frames in this picture.Sample is put into pattern and is provided with three kinds of patterns: operating personnel manually insert specimen container the manual mode that aspirating specimen mouth 18 carries out aspirating specimen; Operating personnel are in advance with sample and reagent mix formation determination sample, inhale the pre-dilution mode of Trace Blood of moving this mensuration sample with aspirating specimen mouth 18; The closed mode of sample is provided by the conveyer that transports specimen container automatically.As species of samples, be provided with normal blood sample routine (Normal), HPC (hemopoietic progenitor cell) sample (HPC) and body fluid (Body Fluid).Operating personnel can specify sample to put into pattern, mode determination and species of samples respectively.If operating personnel specify the blood measuring pattern, then species of samples is appointed as routine (Normal), specify any sample to put into pattern and mode determination again.If specify the humoral determination pattern, then operating personnel specify " manual mode " in the pattern of putting into respectively, one of in subitem detects, specify among " CBC+DIFF ", " CBC+DIFF+RET ", " CBC+DIFF+NRBC " and " CBC+DIFF+NRBC+RET ", in species of samples, specify body fluid (Body Fluid).In step S4, operating personnel so specify desirable mode determination.Carry out blood measuring (selecting N) if operating personnel do not change the mode determination of initial setting, then assign to begin to measure and indicate by the beginning switch at step S5.Microcomputer 6 receives and begins to measure indication (step S6), inhales from the aspirating specimen mouth and moves blood preparation (step S7).
After blood preparation was inhaled and moved, sample was imported into sampling valve 12 as mentioned above, measured needed sample (step S14) according to the subitem detection kind modulation of mode determination.Implement to measure the mensuration operation (step S16) of sample then.Such as, when subitem detection kind is set at " 7 ", the various mensuration samples that preparation HGB, WBC/BASO, DIFF, RET, NRBC, RBC/PLT use.Measured with the mensuration sample by leucocyte detecting device 41 couples of WBC/BASO, DIFF, RET, NRBC then, 42 couples of RBC/PLT measure with the mensuration sample by the RBC/PLT detecting device, and 43 couples of HGB measure with the mensuration sample by the HGB detecting device.At this moment, leucocyte detecting device 41 only is provided with one, and therefore, NRBC, WBC/BASO, DIFF, RET respectively measure sample and import leucocyte detecting device 41 successively by the order of NRBC, WBC/BASO, DIFF, RET, measure item by item.In service in this mensuration, exerciser 62 is drawn distribution of particles figure (scatter diagram, histogram).At this, just the process according to DIFF mensuration gained optical information drafting scatter diagram describes.Exerciser 62 is a characteristic parameter with side scattered light and the side direction fluorescence signal in the light harvesting signal of being exported by leucocyte detecting device 41 in DIFF measures, and draws two-dimentional scatter diagram (distribution of particles figure).This scatter diagram (to call the DIFF scatter diagram in the following text) is X-axis, is that Y-axis is drawn with the side direction fluorescence intensity with the lateral scattering light intensity, general " erythrocyte ghost population ", " lymph population ", " monokaryon population ", " neutrophilia+basophilla population " and " acidophil granules subgroup " of occurring.These population are discerned by handling the DIFF scatter diagram by data analysis unit 64.
Then, carry out analyzing and processing (step S18) according to measuring gained distribution of particles figure.In this analyzing and processing, the DIFF scatter diagram that exerciser 62 was drawn when the data analysis unit 64 dialogue cell detection devices 41 of microcomputer 6 were measured DIFF mensuration sample is categorized as: four leucocyte groups shown in Figure 12 (lymphocyte populations, monocyte group, neutrophilia+basicyte group and acidophic cell group) and erythrocyte ghost group.In the analyzing and processing of present embodiment, the distance between each particle divided from scatter diagram and the centre of gravity place of each group can obtain the degree of membership of each particle to each group.Be divided into each group according to each particle of these degree of membership.This method for classifying particles is put down on the 5-149863 communique in patent disclosure and is documented.Measure on the gained scatter diagram at WBC/BASO, be categorized as basicyte group, basicyte leucocyte group and erythrocyte ghost group in addition.The result who the result (with reference to Figure 12) and the WBC/BASO scatter diagram analyzing and processing of leucocyte four classification and counting is classified and counted leucocyte two according to DIFF scatter diagram analyzing and processing carries out five classification to the contained leucocyte of blood preparation again.Particularly, data analysis unit 64 deducts WBC/BASO scatter diagram analyzing and processing gained " blood cell count of basicyte " from DIFF scatter diagram analyzing and processing gained " blood cell count of neutrophil(e) cell+basicyte ", can draw neutrophil's the blood cell count and the blood cell count of basicyte respectively.In view of the above, leucocyte is obtained every blood cell count by five classification (lymphocyte, monocyte, neutrophil(e) cell, basicyte and acidophic cell).In addition, in RBC/PLT measures, detect the histogrammic curve valley of one dimension of the characteristic information drafting that records according to detecting device 42, to red blood cell and blood platelet classification.The analysis result of so obtaining outputs on the display 302 of data processing equipment 3 (step S20).
On the other hand, if microcomputer 6 receives when specifying mode determination to be the input of humoral determination pattern as mentioned above at step S5, set and carry out the parameter (service condition) of humoral determination as (step S8) such as used reaction warehouse, minute settings.When in the present embodiment, minute is blood measuring as described later three times.
When switching to the humoral determination pattern (step S9), determinator 2 beginning presequences are handled (step S10) to mode determination by other mode determinations (is the blood measuring pattern at this).Series processing is to prepare for humoral determination before this.What measure under the humoral determination pattern is the low sample of haemocyte components and concentration, therefore, when blood measuring pattern (being shown as " 1: routine " among Fig. 8) switching is set at the humoral determination pattern, to carry out presequence and handle, can not have influence on the humoral determination result to guarantee background.
Presequence is handled and is comprised blank the detection.Blank in series processing before this detects the blank that criterion carried out in than determination of blood cell pattern, and to detect the criterion of (after such as switch power supply and carry out after cleaning automatically) stricter, and the value of setting is number below/.In addition, when setting is the blood measuring pattern by the humoral determination mode switch,,, a presequence do not carry out so handling because background influence (influence of residue) does not generally involve the blood measuring result.When in the humoral determination pattern, measuring humoral specimen repeatedly,, do not handle so do not carry out presequence because can not be subjected to the influence of background usually yet.But humoral specimen also has contains a large amount of particles, therefore, when the humoral specimen analysis result exceeds certain value, can occur on the interface that " measurement result is too high, might influence next sample and measure, and will carry out blank detection.Please by " affirmation "." etc. information, the notifying operation personnel might influence following analyzing specimen result.Operating personnel can carry out blank and detect by " affirmation " button.At this moment, the interface is provided with " termination " button, and as long as operating personnel also can not carry out blank and detect by " termination " button, move to standby interface.Do not detect if carry out blank, then preferably to measurement result mark symbol with a low credibility.Do like this and append blank the detection when can only be defined in necessity, with the waste of time of preventing and reagent class.
The process flow diagram of the presequence treatment step that Fig. 9 implements when the blood measuring mode switch is the humoral determination pattern for mode determination.Cellanalyzer 1 is by implementing blank detect (step S31) at determinator 2 mensuration blank samples, and microcomputer 6 compares measurement result and certain allowable value, judges whether measurement result is lower than allowable value (step S32).When measurement result was lower than allowable value, microcomputer 6 finished the presequence operation, recovered to handle.When measured value during greater than allowable value, microcomputer 6 judges whether to have carried out blank detect (the step S33) of stipulated number (such as three times), if the blank number of times that detects does not reach stipulated number, then returns step S31, implements blank the detection in the afore mentioned rules number of times once more.If blank detection assay result is not lower than allowable value yet in stipulated number, then on display operation part 7, show blank determination result and the picture (step S34) that comprises " affirmation " button, " the blank detection " button, " cleaning automatically " button.If operating personnel are by " affirmation " button (step S35), then microcomputer 6 finishes the presequence operation, recovers to handle.If by " blank detect " button (step S36), then microcomputer 6 turns back to step S31 with processing and carries out blank detection once more.If by " cleaning automatically " button (step S37), then microcomputer 6 is implemented to clean back (step S38) automatically with special-purpose cleaning fluid, and processing is turned back to step S31, carry out blank once more and detect.
After above-mentioned presequence processing finished, cellanalyzer 1 returned holding state (step S11).When operating personnel began humoral determination, the same during with the manual mensuration of blood preparation, the humoral specimen that the aspirating specimen mouth 18 of determinator 2 is inserted in the specimen containers was by the beginning switch.Microcomputer 6 is received and is begun to measure indication back (step S12) and begin to inhale and move humoral specimen (step S13).
After humoral specimen was inhaled and moved, the same humoral specimen with blood preparation was imported into sampling valve 91.13 preparation RBC/PLT measure sample (step S15) by reaction warehouse.Then, measure DIFF by leucocyte detecting device 41 and measure sample, measure RBC/PLT by RBC/PLT detecting device 42 and measure sample (step S17).Under the state of humoral determination pattern, only be DIFF mensuration sample what leucocyte detecting device 41 was measured, therefore,, finish mensuration in the shorter time in the time of also may be than blood measuring even minute is longer than the minute of blood measuring pattern.So, prolong longlyer, can improve the analysis precision of the low humoral specimen of particle concentration than the minute of blood measuring by minute with humoral determination.Minute is long more, and the population of counting will be many more, measures precision and will improve.But minute is long, and the sample disposal ability can descend, and will measure sample delivery limited in one's ability to the syringe pump of leucocyte detecting device 41 simultaneously, is appropriate with 2~6 times therefore.When the minute during in the present embodiment, with the humoral determination pattern is set at the blood measuring pattern 3 times.
On the other hand, it all is to import resistance-type detecting device 41 under any mode determination that RBC/PLT measures sample, measures under certain a fluid stream condition.Carry out analyzing and processing (step S19) according to measuring the gained characteristic information then, analysis result outputs to the display 302 (step S21) of data processing equipment 3.In the analyzing and processing under the blood measuring pattern, analyze DIFF scatter diagram etc., calculate five kinds of leucocyte subclass (neutrophil cell: NEUT, lymphocyte: LYMPH, monocyte: MONO, acidophil: EO, basocyte: information BASO) (quantity and ratio), but in the analyzing and processing under the humoral determination pattern, because blood cell count seldom or be subjected to breakage sometimes, therefore, the formal classification with the part integration is two kinds of subclass (monocyte: MN, apocytes: PMN).Lymphocyte and monocyte belong to monocyte, and neutrophil(e) cell, acidophic cell and basicyte belong to apocyte.Algorithm illustrated in this sorting algorithm and the analyzing and processing under the blood measuring pattern is identical, the Therefore, omited explanation.
Then, the analysis result obtained at step S19 and allowable value (decide threshold values) are compared (step S22).The allowable value of using during blank during the presequence of this allowable value and step S10 is handled detects is same value.When analysis result during greater than allowable value (selecting "Yes" among the step S22), then in step S23, show the blank affirmation interface of detecting 151 of beginning shown in Figure 17.This confirms to show on the interface 151: show that " measurement result is too high, might influence following sample and measure.To carry out blank detects.Please by " affirmation "." information demonstration place 152, ACK button 153 and the cancel button 154 of information.Next, what judge user's input is ACK button 153 or cancel button 154 (step S24), if input is ACK button (choosing " affirmation " in step S24), then implements blank detect (step S25).When the analysis result of obtaining at step S19 during less than allowable value (S22 selects "No" in step) or input be cancel button the time (choosing " cancellation " in step S24), then do not carry out the blank detection, return the processing of step S5.
In body fluid samples, there is haemocyte unusual particle (macrophage and middle chrotoplast, tumour cell etc.) in addition sometimes.Exist the situation of these unusual particles rarely found in the cerebrospinal fluid, but more common in other body fluid hydrothorax and the ascites.Therefore, no matter the body fluid kind how, accurately classify to the haemocyte in the body fluid and count, will get rid of the influence of these unusual particles.Therefore, the present invention is based on this new knowledge of DIFF scatter diagram upside that unusual particle appears at this cellanalyzer, instrument can be measured more accurately as the leucocyte in the body fluid samples of target.This point is not consider in aforesaid conventional art.
Figure 10 measures under the humoral determination pattern for present embodiment cellanalyzer 1, analyzes by body fluid and leucocyte and measure the mode chart of measuring the scatter diagram that sample obtained with the DIFF of reagent preparation.The longitudinal axis of scatter diagram is represented side direction fluorescence intensity (by last, fluorescence intensity is strong more more), and transverse axis is represented lateral scattering light intensity (keep right more, scattered light intensity is strong more).The weak area L F of the fluorescence intensity of scatter diagram is distributed with the erythrocyte ghost Gc that haemolysis produces, and the regional HF that fluorescence intensity is strong is distributed with unusual particles such as middle chrotoplast, and zone line MF is distributed with monocyte Mc, multinuclear leucocyte Pc.Therefore, in the analysis of scatter diagram, be that leucocyte is analyzed with the particle composition that is distributed in the regional MF except that area L F and HF, be categorized as above-mentioned two classes, and counting.In addition, comprise lymphocyte and monocyte among the monocyte Mc, comprise neutrophil cell, acidophic cell and basicyte among the multinuclear leucocyte Pc.
So during the leucocyte in the analysing body fluid, also sometimes in the body fluid contained blood cell count, be that monocyte and multinuclear leucocyte are counted therefore seldom or impaired with leukocyte differential count as significant information clinically.
In addition, there is haemocyte unusual particle (macrophage and middle chrotoplast, tumour cell etc.) in addition in the body fluid sometimes.Exist the situation of these unusual particles rarely found in the cerebrospinal fluid, but more common in other body fluid hydrothorax and the ascites.In the scatter diagram of Figure 10, the karyocyte beyond this leucocyte is distributed in regional HF.In the present embodiment, therefore karyocyte and the leukocyte differentiation beyond the leucocyte, also can be able to be obtained correct leukocyte count even contain this leucocyte karyocyte in addition in the body fluid.By the cell that appears at regional HF is counted, the degree that can provide abnormal cell to occur.In the present embodiment, each cell is divided into area L F, MF and HF according to distinguishing each regional threshold values, also can this threshold values of manual change.
