Description
Technical field
The present invention relates to the biochemical analysis equipment technical field, be specifically related to a kind of biochemistry analyzer detector device of anti-crosstalk.
Background technology
Individual core technology is arranged in the Biochemical Analyzer, is exactly spectrophotometry.Its major function is divided into white light various monochromatic light exactly, and the light of selected wavelength is surveyed tolerance, and with this signal of surveying tolerance as the test general data.Prior art is to place slit array before detector array, and all corresponding wavelength selected of each slit on the slit array is called a passage.The corresponding different slits of different passages, but may crosstalk between the slit, and the so-called herein light that refers to by a slit of crosstalking can arrive in the detector unit of other other slit back, causes other passage to have crosstalk signal to produce.The generation of stopping to crosstalk because this structure itself is had no idea, so the existence of crosstalk signal caused the mutual interference of interchannel phase, the test data accuracy is not high like this, and stability is also bad.
Usually, the wavelength detection scheme that adopts in the spectrophotometry in the Biochemical Analyzer is so mostly, according to clinical requirement, selected one group of wave length scheme, calculate the position at each wavelength place in the wave length scheme again according to the grating of selecting for use, according to the location schemes of calculating, make a stalloy that the slit (slit sizes is identical) that a lot of spacings do not wait is arranged on it, be called slit array.The wavelength that the corresponding needs of each slit in the slit array are surveyed is called a passage again.Slit array is placed on before the detector array, and the detector unit of a corresponding detector array behind each slit so just can realize selecting the luminous intensity amount of wave length scheme.In fact, the slit width of slit array is all very little, great majority are all at several millimeters at zero point, so little size is easy to produce optical diffraction phenomenon, the result of diffraction of light has just caused the light of a slit to be received by the detector unit behind the adjacent slit, and this has just produced the channels crosstalk phenomenon.The generation of channels crosstalk can cause the consequence of very severe, and the accuracy of data is with inaccurate, because there is the light intensity of adjacency channel to add.Data stability is also bad, because the wavelength of adjacency channel correspondence is not the responsive operation wavelength of solution to be measured, has problem of unstable and produces.Therefore eliminating crosstalks be Biochemical Analyzer medium wavelength detecting strategy the problem that must solve.And the thinking that addresses this problem is also very simple, because producing, diffraction must have certain space just passable, therefore as long as being pressed close to detector face, slit array just can solve, crosstalk as basic elimination of needs, must closely be attached on the detector face just passable, diffraction will also can not be crosstalked certainly without any the space like this.But in fact slit array closely is attached on the detector face is impossible realize, even the distance that sometimes reduces between the two also is not easy to realize.Reason is many-sided, and the one, cause and can't press close in some detector array encapsulation.Two, even break through structural restriction since in the detector unit existence of anodal guide wire with and the influence of going up protection glue, do not cause closely to press close to.Three, promptly allow to closely press close to, realize it also being impossible for reality, because closely press close to bring short risk (slit array is a steel) between each detector unit positive pole.Four, even ignore short-circuit risks, this operation of pressing close to very easily causes the damage to anodal guide wire in the detector unit, might cause the injuries such as scuffing for detector face more.Five, even above problem can be ignored, it also is very difficult operating, and wastes time and energy.Below just caused the solution cross-interference issue, unusual difficulty becomes.Common way is that one of distance is operated and the acceptable minor increment of crosstalking easily.Residual software algorithm by thereafter of crosstalking etc. solves.Such solution is halfway, and the problem of bringing of crosstalking also can not solve fully, and the accuracy of data and stability will be had a greatly reduced quality certainly.
