Description
Technical field
The utility model relates to a kind of device of technical field of biological, specifically is a kind of biological immune chromatography chip detector.
Background technology
Since the nineties in 20th century, immunochromatography technique has been widely used in medical science detection, food quality monitoring, drugs detection and environmental monitoring because of its quick, easy, economic, single part of characteristic such as detection develops rapidly.At present, immunochromatography technique develops, and might become the early stage effective and sensitive sieving and diagnosis technology of pathogen, malignant tumour and angiocardiopathy etc. towards high sensitivity, direction quantitative and multivariate detection.So-called biological immune chromatography chip detector is a kind of analyser that immuno-chromatographic test paper strip detects and the result judges that carries out specially.
At present, the immuno-chromatographic test paper strip detection system comprises test strips, matched reagent and checkout equipment.After the reaction of sample to be tested and immuno-chromatographic test paper strip and matched reagent, the biological information on the test strips is by the biological information identifier, through the image acquisition of software, analyzes and adds powerful, obtains a result at last.Because immunochromatography technique is simple to operate, fast, specificity is good, and the result is clear, is easy to judge and preserve, and need not or only need simple instrument and material, so be usually used in that bedside detects and the large tracts of land examination of non-hospital.In order to cooperate these base application, the exploitation of chromatography detection system is inevitable to be developed towards miniature, portable direction.And complete detection system can help operating personnel to obtain testing result more accurately, reduces the influence and the erroneous judgement of environment.
Fluorescence quantum is the very important function nano material of a class, and its diameter is about the 1-10 nanometer.Because the yardstick quantum effect, their performances have unique photoluminescence performance.Mainly show as: emission wavelength ranges is narrow, and the Stocks displacement is big, the quantum yield height, and fluorescence lifetime is long, and chemistry and optical stability are good.Because the overlapping wide ranges of absorption spectrum, the laser that can adopt single wavelength is excitation source, realizes multi-color marking, is particularly suitable for active somatic cell imaging and polycomponent and detects simultaneously.
Find through retrieval prior art, mainly be divided into two big classes based on fluorescently-labeled biological chip testing technology at present, a class is to adopt the laser co-focusing technology, and its shortcoming is the mechanical precision condition influence that scanning accuracy is subjected to two-dimentional mobile platform, the cost of manufacture height, sweep velocity is slow; The another kind of CCD technology that is to use, the disposable whole imaging of finishing chip, sweep velocity is fast, and can not use mobile platform, shortcoming is that ratio of precision copolymerization Jiao method is low.For highdensity dot matrix chip, use the burnt technology of copolymerization usually, the low-density CCD imaging technique that then uses can satisfy the demands.Just at the demand of low end subscriber, detect principle based on CCD, cancelled the mobile platform design, the immuno-chromatographic test paper strip at single detection demand has designed low cost especially, and easily the small throughput detector that moves is easy to applying of chromatography detection technique.
Present pick-up unit adopts " biological chips detection system " of white light such as Chinese patent application number 02156427.2 record mostly, or laser carries out exciting irradiation through after the beam split to detection chip, " the matrix form biochip CCD reading and scanning apparatus " of Chinese patent application number 03149777.2 record, characteristic at the test sample burst of ultraviolel, adopt ultraviolet light directly sample to be excited, save the optical filtering light-dividing device.For the exciting of fluorescence, select for use ultraviolet lamp tube to excite mostly in addition.Generally be refraction, reach the irradiation integration of ultraviolet light, but be to use the multiple refraction of prism, just increased the volume of equipment virtually sample by prism; Also have the annular lamp tube of use that sample is carried out direct irradiation, but the heat production in the ultraviolet lamp tube use has produced influence to image quality again.
The utility model content
The utility model provides a kind of biological immune chromatography chip detector at the prior art above shortcomings, and is easy and simple to handle, volume is small and exquisite, adopts the ring shaped dot matrix formula to arrange, and realizes the uniform and stable of illumination, and testing result is reliable and stable.
The utility model is achieved through the following technical solutions, the utility model comprises: digital camera, camera lens, ultraviolet leds array, magnifying glass and ultraviolet filter, wherein: digital camera, camera lens, ultraviolet leds array, magnifying glass and ultraviolet filter from top to bottom are set in turn on the same axis, and described ultraviolet leds array is made up of several ultraviolet leds lamp ring shooting.
The utility model has adopted LED annular ultraviolet cold light source as excitation source, the CCD analog video camera cooperates image pick-up card to carry out the fluorescence signal collection, wherein led light source distributes ringwise, hole in the middle of camera lens can being passed carries out image acquisition, the LED cold light source is for directly carrying out burst of ultraviolel to sample, and do not use the mode of refraction, successfully significantly reduced the volume of biological immune chromatographic analysis instrument.
The ultraviolet LED illuminator by several independently the LED uviol lamp form, compare other illuminators, at design aspects such as range of exposures, irradiating angle and the depth of parallelisms, have bigger degree of freedom, can reduce irradiation distance, satisfy the more demands of reality.The relative conventional fluorescent lamps of LED photographic system has the longer half life period, can keep stable image input for a long time.Response time is fast.It is low to generate heat, thereby greatly reduces the interference of light source to image.
