Immunochromatography analyzer

Abstract

The invention discloses an immunochromatography analyzer which comprises a complete machine frame, a sample injection assembly is arranged in front of the complete machine frame, and the sample injection assembly comprises a sample cache region, a sample recovery region and a sample conveying region; the sample conveying region is internally provided with a sample feeding and conveying mechanism for conveying a sample container rack from the sample buffer region to the sample recovery region; a sample mixing assembly and a sampling assembly which are located above the sample conveying region are arranged in the complete machine frame, and the sample mixing assembly is located on the upstream side of the sampling assembly; a detection assembly is arranged in the complete machine frame and provided with an incubation station corresponding to the sampling assembly, a camera shooting station used for shooting reagent cards and a scanning and card kicking station used for conducting optical detection on the reagent cards and removing the reagent cards after detection is completed. A reagent card rotating mechanism for driving the reagent cards to sequentially pass through the incubation station, the camera shooting station and the scanning and card kicking station is arranged in the detection assembly.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an immunochromatography analyzer. Background technique [0002] The detection principle of the immunochromatography analyzer is based on the specific immune response of antigens and antibodies, and assists clinical diagnosis by detecting different items on samples such as whole blood, peripheral blood, serum and plasma. In order to meet the current customers' needs for quantitative / qualitative detection and large throughput, and to meet the development trend of automation and simplification of POCT detection, large throughput and full automation are the development trends of immunochromatographic analyzers. [0003] Although the existing immunolayer analyzers can meet the detection requirements to a certain extent, there are still the following deficiencies: [0004] 1. Insufficient degree of automation: most of the existing immunochromatographic analyzers are manual or ...

AI Technical Summary

Problems solved by technology

[0004] 1. Insufficient degree of automation: most of the existing immunochromatographic analyzers are manual or semi-automatic instruments, which require manual sample dilution, sampling and spotting, and insertion of reagent cards. The operation is cumbersome and inefficient, and improper operation is likely to cause pollution , affecting the test results;

[0005] 2. The fully automatic immune analyzers on the market have disadvantages such as small cartridge throughput, complex structure of reagent cartridges and automatic card feeding device, high cost, and large space occupation, which is not conducive to reducing the volume of the instrument;

[0006] 3. At present, the reagent cards of immune analyzers on the market are mainly stored by adding refrigeration and dehumidification components in the card compartment or preventing desiccant in the reagent card box. The effect is limited, which is not conducive to the long-term storage of reagent cards in the card compartment.

Therefore, the operator needs to take out the reagent card that is not tested for too long and put it back into a dry sealed bag, which is cumbersome and even affects the test results
