Reagent card storage device, reagent card feeding device and immunochromatographic analyzer

Abstract

The invention discloses a reagent card storage device which comprises a shell, a reagent card bin is arranged in the shell, and a plurality of reagent card box installation stations used for installing reagent card boxes are arranged in the reagent card bin side by side. The invention further discloses a reagent card feeding device which comprises the above reagent card storage device. A reagent card feeding bin located below the reagent card bin is further arranged in the shell, and a card feeding and taking mechanism used for taking out reagent cards from the reagent card boxes is arranged in the reagent card feeding bin. The invention further discloses an immunochromatography analyzer which comprises the reagent card feeding device. The reagent card storage device, the reagent card feeding device and the immunochromatography analyzer have the advantage of being large in card bin flux.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a reagent card storage device, a reagent card feeding device and 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 demand for quantitative / qualitative detection and large throughput, and to meet the development trend of POCT detection automation and simplification, large throughput and full automation are the development trend of immunochromatographic analyzers. [0003] The existing immunochromatography analyzer mainly has the following deficiencies: [0004] 1) Most of the existing immunochromatographic analyzers are manual or semi-automatic instruments, which require manual insert...

AI Technical Summary

Problems solved by technology

[0004] 1) Most of the existing immunochromatographic analyzers are manual or semi-automatic instruments, which require manual insertion of reagent cards, which is cumbersome and inefficient to operate, and improper operation is likely to cause pollution, which will ultimately affect the test results;

[0005] 2) The fully automatic immune program analyzers on the market have the problems of 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) The fully automatic immune program analyzers on the market need to manually open the door, and then the operator identifies the designated cartridge and then manually removes the cartridge. The operation is cumbersome and the efficiency is low and the experience is poor;

[0007] 4) The reagent card transports the sample from the sample drop position to the reaction position through capillary action. All reagent cards need to be kept dry. The existing immune analyzer is not conducive to the long-term storage of reagent cards in the card compartment. Reagent cards that have not been tested for too long are taken out and put back into a dry sealed bag, which is cumbersome to operate and may even affect the test results
