Abstract
The utility model discloses a gold label detector for colloidal gold. The detector comprises an image collecting system for collecting images of a test strip, a central control system for analyzing and processing the collected images and a printing device for printing the analyzed and processed result. The image collecting system and the printing device are connected to the central control system and are interactive in information. The utility model provides the gold label detector for colloidal gold to detect information of the test strip qualitatively and quantitively and record the analyzing data result which can be printed and output.
Description
Technical field
The utility model relates to a kind of automatic detection device of Biosample, especially a kind of collaurum gold mark detector, the qualitative and quantitative analysis that can be correlated with to the test strips of being made by collaurum (melamine, Clenbuterol etc.).
Background technology
The colloidal gold strip baffled photometer is called for short collaurum gold mark detector, quick and precisely quantitative test colloidal gold immuno-chromatography test paper strip.According to the characteristic of colloid gold particle between the 10-100nm to the peak absorbance of light, by visible light or laser scanning, measure the reflection case on the colloidal gold strip, by micro computer the integration that detects band and quality control band is compared, calculate the quantity of colloid gold particle on the relative quality control band of colloid gold particle of immune combination, calculated by the concentration of check reagent by formula again.And then realize that the detection of dynamic of colloidal gold immunochromatographimethod reaction is had good response characteristic in big concentration range.
(colloidal gold immunochromatography assay GICA) is a kind of solid phase labelling immunoassay technology that multiple technologies such as colloidal gold-labeled method, immunoassay technology and chromatographic analysis technology are organically combined to the colloidal gold immunochromatographimethod technology.Easy and simple to handle, quick because of it, and has very high specificity and susceptibility, in the clinical medicine check, obtain development quickly, be widely used in the clinical detection as diseases such as human chorionic gonadotrophin, the plague, hepatitis B, parasite, myocardial damage, acquired immune deficiency syndrome (AIDS) at present.
Collaurum can show numerous characteristics, particularly absorption Spectrum characteristic when size is reduced to nanometer scale, have important use in fields such as materialogy, clinical medicine, life sciences and be worth.To studies show that of colloid gold particle absorption Spectrum characteristic, when the nanogold particle particle diameter was between 10-100nm, its absorption peak was between 510-550nm; Along with the increase of nanogold particle particle diameter, its absorption peak moves east to ruddiness, and is the linear changing relation basically between absorption peak wavelength and the particle diameter, so a large amount of nanogold particle is shown as kermesinus when assembling.
Collaurum is the aqueous solution of gold chloride, and it aggregates into the colloid gold particle of specific size (3nm-80nm) under the effect of reductive agent, and owing to electrostatic interaction forms a kind of stable colloidal state.Colloid gold label comes down to macromolecules such as protein molecule and is adsorbed to the bag on colloid gold particle surface by process, adsorption mechanism is colloid gold particle electronegative character under alkali condition, lean on electrostatic interaction and strong bonded with the positive charge group of protein molecule, thereby have good stable.The immunochromatographiassays assays method that with the collaurum is label has been widely used in fields such as histopathology and immunology diagnosis.
Although the colloidal gold immunochromatographimethod technology has a wide range of applications in clinical medicine check field, at present only with ocular estimate to dripping having or not of on gold-marking immunity test strips checking matter and do qualitative or sxemiquantitative being judged.Have following shortcoming: 1) measurement result is subject to the interference of human factor, and objectivity is poor; 2) can not monitoring bio the dynamic process of reaction.3) inaccurate.
The utility model content
At existing ocular estimate to be subject in the prior art to think factor to disturb the not high problem of accuracy, the utility model provides a kind of collaurum gold mark detector, test strip information that can be qualitative, quantitative, and record analysis data result, printable output.
To achieve these goals, a kind of collaurum gold of the utility model mark detector, described collaurum gold mark detector comprises for the image capturing system that test strips is carried out image acquisition, the image of gathering is carried out the central control system of analyzing and processing and the printing equipment that the result of analyzing and processing is printed, described image capturing system and printing equipment all are connected on the described central control system, interactive information.
Further, described central control system connects the multiplex image acquisition system simultaneously, and the described image capturing system of multichannel can send to central control system simultaneously with image information.
Further, described image capturing system comprises camera and lamp plate, and described camera is connected with described central control system, and described lamp plate provides light source when the camera collection image.
Further, described central control system is carried out analyzing and processing by the image information of OpenCV, draws T/C line ratio, and then draws corresponding reagent concentration.
Further, also be connected with the display screen for man-machine interaction on the described collaurum gold mark detector, described display screen is connected with described central control system.
Further, described central control system is provided with the USB expansion board that can be connected with external input device, and described multiplex image acquisition system is connected with central control system by the USB expansion board.
The utility model provides a kind of collaurum gold mark detector, and the setting of multiplex image acquisition system can detect a plurality of test paper information simultaneously, is conducive to the big data quantity analysis, has improved detection efficiency; The USB expansion board can be connected with external input device, can realize communications such as information typing, utilizes central control system that test paper information is carried out analyzing and processing; Utilize printing device that result is recorded on the paper, be convenient to read and preserve; Display screen is convenient to man-machine interaction.
