Problems solved by technology

[0006] 2.1 The cost of the test card is high, including the cost of the card itself (its ABS (acrylonitrile-styrene-butadiene copolymer) material, its abrasive tool making and its manufacture) and the assembly cost of loading the reagent strip into the card
[0007] 2.2 The appearance and size of test cards from different reagent manufacturers are different. Therefore, the rapid immunoassay analyzer must have different test card holders
The cost of the analyzer also increases a lot

Embodiment 1

[0049] Such as Figure 5 As shown, this embodiment shows how to use the reagent strip carrier device of the present invention to operate multiple immunochromatography reagent strips.

[0050] Such as image 3 As shown, the immunochromatographic reagent strip is a strip structure, and its structure is: on a plastic bottom plate, the arrangement is continuous (with a small amount of connection at the joints) including: (1) a liquid storage membrane 7 at one end ( sample and reagent), (2) the nitrocellulose membrane area 8 coated with the reaction and results of the antigen or antibody preparation in the middle, (3) the absorbent paper 9 at the other end. According to the needs of use, dry reagents are buried under the junction of the liquid storage membrane 7 and the nitrocellulose membrane area 8 on some reagent strips.

[0051] Such as figure 1 As shown, the reagent strip carrier device of the present invention is in the shape of a disc and includes a plurality of detachabl...

Embodiment 2

[0058] Such as figure 2 As shown, this embodiment shows how to use the reagent strip carrier device of the present invention to operate a single immunochromatography reagent strip.

[0059] The steps to use are as follows:

[0060] 1. get the carrier device containing 10 immunochromatography reagent strips in step 1 in embodiment 1 (see figure 1 ).

[0061] 2. If figure 1 As shown, along the row of holes 3 in the middle part adjacent to the first groove structure 5 and the second groove structure 6, the first groove structure 5 is separated by slight tearing. will be like image 3 In the shown reagent strip, the end of the absorbent paper 9 bears against the same end of the first groove structure 5, and is fixed under the restriction button 4 of the reagent strip.

[0062] 3. Place the carrier device containing the first groove structure 5 of the reagent strip on a horizontal surface, and complete the operation procedure of the reagent strip according to the product inst...

Embodiment 3

[0066] Such as Figure 6 As shown, this embodiment shows how to use the reagent strip carrier device of the present invention to operate two immunospot reagent strips.

[0067] Such as Figure 4 As shown, the immunospot reagent strip is a rectangular nitrocellulose membrane coated with antigen attached to a plastic base plate.

[0068] The steps to use are as follows:

[0069] 1. Take one such as Figure 6 The reagent strip carrier device of the present invention is shown.

[0070] 2. Separate the 1st and 2nd trough structures by slight tearing along the row of holes 3 in the middle part adjacent to the 2nd and 3rd trough structures (the 1st and 2nd trough structures are still connected ).

[0071] 3. Insert an immunospot reagent strip into each of the two trough structures, and the end with the top mark 10 is consistent with the same end of the same trough structure, and is fixed under the reagent strip restriction buckle 4 .

[0072] 4. place the groove type structure ...

Abstract

The invention discloses a reagent strip carrier device used for a rapid immunoassay analyzer. The reagent strip carrier device is disc-shaped and comprises multiple separable groove-shaped structures used for placing reagent strips. Besides, the invention also discloses a use method for the reagent strip carrier device. The reagent strip carrier device used for the rapid immunoassay analyzer is low in cost and convenient for use, and can flexibly select one or more of (high flux) reagent strips to analyze at one time.

Description

technical field [0001] The invention relates to a rapid immunoassay analyzer, in particular to a reagent strip carrier device for the rapid immunoassay analyzer. In addition, the present invention also relates to a method of using the reagent strip carrier device. Background technique [0002] Nowadays, there are more and more immunochromatographic tests and immunospot tests using rapid immunoassay analyzers, such as for the detection of hepatitis B, AIDS, etc. Card case: consists of a bottom plate on which reagent strips can be placed and a panel covering it; generally, the overall volume of the smallest test card is 7cm (length) x 2cm (width) x 0.6cm (thickness). The operation of the test card is nothing more than the following steps: [0003] 1. Complete the necessary steps such as adding samples, adding reagents, washing, and incubating on the test card; [0004] 2. Put the test card into the analyzer to complete the analysis. [0005] The disadvantages of using trad...
