Description
Technical field
The present invention relates to biological sample analysis technical field, main relevant blood analyser device, is specially the blood analyser of a kind of disposable specimen cup, this specimen cup of adapted, and the using method of this blood analyser.
Background technology
Most popular is at present three-classification blood analyzer, namely to the red blood cell in blood, white blood cell and blood platelet three blood analysis instrument of class classified counting of leucocyte.So far the most blood analysers used in the world all adopt electrical impedance method (Electrical Impedance, i.e. Coulter principle CoulterPrinciple) carry out blood count and stereometry, its Cleaning Principle be haemocyte by will resistance variations be produced during aperture, achieve the automation of blood count accordingly.
The critical piece of this kind of analyzer is aperture plate, also referred to as sensor (Transducer).Aperture plate is inserted in the cell suspension of isotonic electrolyte solution dilution, and be filled with dilution inside aperture plate, and have an interior electrode, there is an external electrode in outside.The conduction property of cell is lower than isotonic dilution, and after electrode switches on power, produce stable electric current between the electrode being positioned at aperture both sides, dilution is flowed by aperture.The conductibility of cell is less than dilution, and when cell is by aperture, in aperture induction zone, resistance increases, and occurring a pulse signal, being called as and passing through pulse in causing voltage change instantaneously.The voltage change that cell volume causes more greatly is larger, generation higher by pulse amplitude.When electric current I and impedance Z are stable, can be determined cell volume by the measurement of paired pulses size, be distinguished different types of cell, the number of recording impulse can obtain Cytometric result.
Measurement red blood cell, leucocyte, hematoblastic 3 classification blood analyzers are furnished with 2 kinds of specimen cups, and small aperture is different, a kind of for measuring red blood cell and blood platelet, another kind of for measuring leucocyte.Specimen cup has the rear room of the cup of electrode in a band and a band external electrode, has aperture to communicate between two Room.
For making the sample solution cell after process stable can flow through aperture, also the pressure of cup must be greater than the pressure of rear room, needing again foundation and gas circuit mechanism corresponding to fluid path to set up a stable pressure system in forward and backward room for this reason.Also indispensable pulse signals carries out the electronic system that identifies, add up, classify.
Most importantly, in order to the blood sample volume gathered is accurate, blood analyser needs configuration in specimen cup, add the dilution of accurate quantification and the liquid-way system of hemolytic agent, also need the liquid-way system configuring quantitative collection blood sample and be assigned in different specimen cup, the mechanical system matched with liquid-way system comprises: precision syringe, point blood valve, stepper motor and control and feedback circuit accordingly.After detection counting terminates, the fluid path of all contacted samples all needs to carry out cleaning, recovering clean conditions, therefore blood analyser also will configure cleaning systems.
From analyzing above, existing conventional 3 classification cellanalyzers at least comprise electronics, pressure reduction and fluid path, machinery, multiple system such as clean, multisystem just needs to join more electronic control circuit, complex structure, initial stage cost of purchasing is high, and the probability of each system jam of complexity can increase, maintenance cost is high.Particularly the aging generation that may cause squib, leakage of fluid path pipeline, not only can corrode instrument, also bring biological risk.Waste liquid after detection also will process especially, otherwise will have biological risk.Part, the parts of instrument internal are many, are difficult to miniaturized, and mobile difficulty, more cannot carry.
In addition, existing blood analyser needs supporting reagent dilutions, detects into injecting a certain amount of reagent in specimen cup at every turn.Behind reagent Kaifeng, the term of validity is of short duration, and expired reagent can only be scrapped.For the user that test volume is little, often reagent Kaifeng after cannot be used up before the deadline, reagent scrap the cost turn increasing user undoubtedly.
Summary of the invention
The object of the invention is the disposable specimen cup designing a kind of blood analysis, it comprises cup and rear room, Cytometric aperture is had between cup and rear room, respectively there are Stress control interface and circuit interface in cup and rear room, after being connected with the interface board of blood analyser, can be connected with the pressure reduction control module of blood analyser and testing circuit module, reagent needed for cup and rear indoor preliminary filling, only with precision syringe, blood sample need be injected cup can test.Because of without liquid-way system, also without the need to supporting mechanical system and cleaning systems.
