s302, conveying the reagent bottles to a reagent strip inserting position, and inserting a reagent strip into each reagent bottle;
s303, carrying out first photographing after 8 minutes, carrying out first photographing recording on the CT lines of the plurality of reagent strips, and carrying out first photographing recording on the CT lines of the plurality of reagent strips;
and S304, taking a second photo after 15 minutes, recording the second photo of the CT lines of the plurality of reagent strips, and automatically judging whether the sample is positive, negative or invalid according to the results of the two photos.
Of course, the above method may be performed without the step S303, and the step S304 is performed directly, that is, after 15 minutes, the image is taken, and the sample is automatically determined to be positive, negative or invalid according to the captured CT line.
In this embodiment, the lysate needs to be filled in a reagent bottle in advance, after a medical worker takes a nasal/pharyngeal swab with a cotton swab, the cotton swab is placed in the reagent bottle, a plurality of reagent bottles (for example, 10) are placed in a fixed frame, a plurality of fixed frames are used for placing sample frames, one or more sample frames are simultaneously loaded on the machine, the fixed frame is conveyed to a test strip insertion position, the test strip is simultaneously inserted into the plurality of reagent bottles, as shown in fig. 12, the fixed frame is continuously conveyed, the first photographing position is reached after 8 minutes, the first photographing record is simultaneously performed on CT lines of the plurality of reagent strips, the fixed frame is continuously conveyed, and the second photographing position is reached after 15 minutes; and simultaneously, carrying out secondary photographing recording on the CT lines of the plurality of reagent strips, and automatically judging whether the sample is positive, negative or invalid by the instrument according to the results of the two photographing.
In summary, the invention discloses a colloidal gold antigen virus detection device and a method thereof, wherein the detection method comprises the following steps: inserting the cotton swab with the sample into a reagent bottle, rotating for several weeks, and inserting the reagent bottle onto a carrier of a previous conveying horizontal section of an inverted U-shaped conveying belt; the transmission mechanism conveys the carriers and the reagent bottles to one side of a reagent strip inserting mechanism, and the reagent strip inserting mechanism inserts the reagent strips into each reagent bottle; after 15 minutes, the transmission mechanism conveys the carrier and the reagent bottle to one side of a photographing code scanning mechanism, the photographing code scanning mechanism photographs a C line and a T line on the reagent strip and scans a bar code on the reagent bottle, whether a corresponding sample is positive, negative or invalid can be judged according to a photographing result, and finally, an uploading test result is stored; the carrier and the reagent bottle are conveyed to one side of the sample unloading mechanism by the transmission mechanism, the sample unloading mechanism separates and recovers the reagent bottle and the carrier, and the carrier enters the next cycle, so that the whole detection process is carried out on automatic equipment, the detection efficiency can be effectively improved, the method is particularly suitable for large-batch detection, and the detection work can be rapidly completed; in addition, the automatic photographing and scanning of the photographing and code scanning mechanism are adopted, and the CT lines are judged on the photos through an image recognition technology, so that the probability of artificial misjudgment is effectively reduced.
