Description

Little multispectral fluorescence reception and disposal system
Technical field
The present invention relates to biochemistry detection and external medical diagnostic equipment, relate in particular to a kind of little multispectral fluorescence reception and disposal system.
Background technology
At present, the employed instrument of medical institutions' clinical diagnosis and biological detection, (Picymerase Chain Reaction) PCR is feature all take the PCR in the fluorescent collecting system of employing.In the PCR reaction system, add the primer that contains fluorescent material, fluorescent material sends the light of another feature wavelength under the excitation source irradiation of specific wavelength, detect the light intensity that fluorescent material is launched in the PCR course of reaction by photomultiplier acceptance, optical fiber optical signal transmission, discrete optical filter light splitting, monitoring pcr amplification reaction process.Draw real-time analytic curve by computer software analysis, calculate the Ct value, provide the nucleic acid concentration value of sample starting template, carry out detection and the genetic analysis of the various pathogen of DNA/RNA.
It is discrete optical filter light splitting that existing clinical diagnosis, biochemical instrument adopt the method for designing of fluorescence gathering system, the optical fiber optical signal transmission, photomultiplier is accepted fluorescence signal and is carried out opto-electronic conversion, process post analysis calculating original gene content and expression formula through preposition amplification and data, detect the situation of sample tissue element variation.This project organization cost is high, and the collection of light and opto-electronic conversion are complicated, the poor stability of authentic specimen acquisition of information, and measurable number of samples is restricted.
Adopt common photomultiplier, to convert faint optical signal to electric signal, but when illumination is mapped to photomultiplier, photocathode inspires photoelectron in vacuum, photoelectron enters dynode system by the focusing board electric field, obtain multiplication by further Secondary Emission and amplify, the electronics after the amplification is collected with anode and is exported as signal.Owing to adopted the Secondary Emission dynode system, so photomultiplier has higher sensitivity in the photodetection of the emittance of ultraviolet, visible light and near-infrared region, be widely used in the clinical diagnosis of carrying out optical measurement and spectral analysis and biochemical instrument.But common photomultiplier once can only be measured an information, and passage only has one, has limited the measurement of multi-channel information; Photomultiplier in actual use, detection sensitivity reduces because of strong illumination or because irradiation time is long, stops after the irradiation again part and recovers, and " tired " phenomenon occurs; The sensitivity of photomultiplier photoanode surface each point is inhomogeneous.Photomultiplier also needs accessory circuit such as high-voltage power supply, amplification and Discr., cool room, magnetic shielding, base etc. in addition, and this is high to the requirement of environment just so that the volume of whole system is large.
In recent years, along with the development of semiconductor technology, multi-anode photomultiplier and silicon photomultiplier are come out one after another, and its common characteristics are to make many very thin photomultipliers form matrix, increase detection channels, reduce the volume of photomultiplier; Optical detection unit adopts the optical fiber lens arra.But the anode end of multi-anode photomultiplier is subjected to the restriction of fine wire, and it is measured passage and can only accomplish hundred at present.The optical fiber that is used for optical detection unit, for sample carriers, owing to be point measurement, the light signal of detection and transmission is the real information of complete representative tested sample accurately.Aspect the fixed form of optical fiber: optical fiber is fixed on the bottom of sample, if the location will definitely not affect the detection quality of signal; Optical fiber is fixed on the top of sample, and in the experimentation, the movement that microwell plate can be frequent not only affects the quality of measurement but also brings inconvenience to the operator, simultaneously optical fiber contaminated accuracy that also can reduce measurement in experimentation.
Adopt discrete optical filter light splitting, in a large amount of experimentations, need frequent adjustment optical filter wheel to make the discrete different wavelength of optical filter light splitting, so not only can produce artificial noise, because the Mechanical Moving of optical filter wheel can cause the position skew of obtaining image, the quality of image information is obtained in impact simultaneously.
