Description
Technical field
The present invention relates to a kind of people and animal blood classifying apparatus and method, particularly relate to a kind of based on super continuous
Instrument and the method for sealing the contactless discriminating of test tube blood sample of unrestrained comprehensive laser spectrum.
Background technology
China all takes credit system for customs's import and export of blood and other kinds biomaterial at present, and
The verity of different kind organism material cannot directly be detected the most for various reasons.Particularly relate to blood sample
Such special material, open contact many times condition of sampling is not allowed to.On the one hand blood
Liquid sample may be detected operational pollution；On the other hand the virulence factor that blood sample self may carry can be right
Testing staff causes occupational exposure.In view of the foregoing, the exploitation contactless Fast Detection Technique of blood sample
Method is the most urgent.
Human blood is similar to animal's whole blood main constituent, is mainly made up of hemocyte and blood plasma, all takes on a red color,
Naked eyes are difficult to distinguish, but people and animal blood cell and the pattern of blood plasma and composition have technicality, selection
Appropriate method just can distinguish human blood and animal blood.The detection method of classical contact can be examined
Measure part blood parameters, the blood between different genera can be carried out according to these blood parameters and differentiate.Mesh
Before, commercial use more blood to differentiate product is all based on greatly flow cytometry, contact need to be carried out and decline sampling
Obtain the parameter of the representative phylogenetic feature of blood.It is a problem being rich in challenge that contactless blood differentiates,
Because the major part either whole blood that is sealed in cuvette of species or the sample such as serum, blood plasma, its
Ultraviolet, spectral coverage visible, infrared, the optical characteristics externally reflected is the most similar, in the detection of non-sampled,
The means relying on optics are differentiated extremely difficult.
First, in test tube, the blood products of encapsulation may be containing the anticoagulant of different components, including heparin, second
Ethylenediaminotetraacetate (edetate) (edta salt), citrate, oxalates etc., tube material is probably quartz in addition
Glass or PET etc., major part test tube the most all labels.These interference factors, will have a strong impact on
The optical property of blood so that conventional optics and spectrographic technique are helpless on sealing test tube blood differentiates.
For these reasons, exploitation one seals test tube blood for people and animal, including whole blood, serum,
The contactless taxonomic history instrument of blood plasma and method are urgent need to solve the problems.
For this problem, the present invention propose a kind of based on visible to the super continuous unrestrained comprehensive laser spectrum of mid-infrared
For sealing instrument and the method for the contactless discriminating of test tube blood sample, use wide spectrum super continuous spectrums laser
The integrating sphere of source and particular design is core instrument hardware structure, obtains the unrestrained comprehensive laser spectrum of different sample
Data, set up different plant species, different test tube, the spectra database of different blood, and based on principal component analysis
Method (principal components analysis is called for short PCA) calculates these spectroscopic datas and obtains principal component analysis
Shot chart, obtains people and animal's whole blood, blood plasma, the cluster areas of serum, by these regions in shot chart
As differentiating that criterion carries out people and seals blood sample noncontact discriminating with animal test tube.
Summary of the invention
It is an object of the invention to provide a kind of based on visible to the super continuous unrestrained comprehensive laser spectrum of mid-infrared
For sealing the instrument of the contactless discriminating of test tube blood sample, people and animal's whole blood, blood plasma and blood can be carried out
Clear automatic identification, meets the detection quarantine departments demand to blood products Rough Inspection.
The technical scheme is that and be achieved in, sealing blood based on super continuous unrestrained comprehensive laser spectrum
The hardware system of liquid identifier is mainly by power supply module, visible spectral coverage spectrogrph, infrared spectral coverage spectrogrph, Y
