Description

Immunochromatography detection device Technical Field The utility model relates to the technical field of immunochromatography, in particular to an immunochromatography detection device. Background Immunochromatography is a rapid diagnosis technique developed in the 90 th century, and its principle is that a specific antibody or antigen is immobilized on a certain zone of a Nitrocellulose (NC) membrane, and when one end of the dried NC membrane is immersed in a sample (usually urine, blood or the like, body fluid), the sample moves along the membrane to the other end due to capillary action, and when the sample moves to a region where the labeled antibody or antigen is present, the target antibody or antigen contained in the sample specifically binds to the labeled antibody or antigen, and color is developed by a labeling technique. The existing immunochromatography detection device comprises a bottom shell and a top cover, an observation window is arranged on the top cover, a detection strip made of NC film materials is arranged between the bottom shell and the top cover, antibodies or antigens are marked on the detection strip, and then a color reaction can be carried out on sample liquid to be detected. The existing immunochromatography detection device can only detect one or two sample liquids at the same time or can only detect one or two groups of sample liquids at the same time, and has the defects of low use efficiency and unfavorable long-term use. Based on the above, the present utility model designs an immunochromatography detection apparatus to solve the above-mentioned problems. Disclosure of utility model The present utility model is directed to an immunochromatography detection apparatus for solving the above-mentioned problems. In order to achieve the aim, the immunochromatography detection device comprises a center block, wherein bottom shells are arranged on the periphery of the center block, top covers are arranged on the tops of the four groups of bottom shells, observation windows are arranged on the top covers, accommodating grooves are formed in the center block, positioning structures are detachably arranged on the accommodating grooves, detection strips are further arranged between the bottom shells and the top covers, observation areas are arranged on the detection strips and located at corresponding positions of the observation windows, positioning blocks are arranged at one ends of the detection strips, and through grooves are formed in positions, close to the bottom shells, of the center block. Through adopting above-mentioned technical scheme, can detect four kinds of sample liquids simultaneously, perhaps carry out four times simultaneously to same kind of sample liquid and detect, and then promote immunochromatography detection's effect. Preferably, the positioning structure comprises a top sheet, the top of the top sheet is fixedly connected with a positioning block, the positioning block is cross-shaped, the bottom of the top sheet is fixedly connected with a cross-shaped isolation block, the bottom of the isolation block is fixedly connected with a bottom sheet, four groups of sample injection holes are formed in the top sheet, and the four groups of sample injection holes are staggered with four sides of the positioning block. By adopting the technical scheme, the sample liquid is respectively input to the positioning block from the four groups of sample injection holes, then the sample liquid is subjected to color reaction in the observation area on the detection strip, and finally the observation is performed at the position of the observation window. Preferably, four sides on the alignment block are respectively provided with different colors. By adopting the technical scheme, the device can be better resolved. Preferably, the center block is further provided with a positioning mark, and the positioning mark is matched with the positioning block. Through adopting above-mentioned technical scheme, can carry out fine dismouting to location structure. Preferably, a plurality of limiting blocks are fixedly connected to two sides of the top of the bottom shell, and the limiting blocks are L-shaped. Through adopting above-mentioned technical scheme, the stopper can be simultaneously to detecting strip and top cap spacing. Preferably, the top surface of the top cover is fixedly provided with anti-slip ribs. Through adopting above-mentioned technical scheme, can be convenient to the top cap dismouting. In summary, the application has the following beneficial technical effects that by installing four groups of detection strips, four groups of different sample liquids can be detected simultaneously, or four times of detection can be performed on one sample liquid simultaneously, so that the immunochromatography detection efficiency is improved, and the detection strip can be conveniently disassembled and assembled through the positioning structure, so that the detection strip is
