Description

Technical Field

[0001] The invention relates to the technical field of kits, in particular to a rapid detection kit for swine fever antibodies. Background Art

[0002] The Classical Swine Fever Antibody Rapid Detection Kit is a tool used to quickly detect the level of Classical Swine Fever antibodies in pigs. By detecting Classical Swine Fever antibodies, we can understand the immune status of the pig herd, evaluate the immune effect of the vaccine, and provide an important basis for the prevention and control of Classical Swine Fever. However, the reagents in the existing detection kits are prone to become invalid due to improper storage, which in turn affects the test results, and there are certain defects.

[0003] The defects of existing detection kits are: 1. In the patent document CN212244595U, the dust removal effect in the test kit box is mainly improved by a ventilation pipe provided with a filter, but it does not take into account that the reagents in the existing test kits are easily invalidated due to improper storage, thereby affecting the test results; 2. In the patent document CN209764880U, four areas are set, each of which can be marked with a label. When conducting a swine fever antibody detection experiment, each antibody detection reagent can be quickly distinguished, which is convenient for distinguishing and classifying antibodies. It does not take into account that the detection reagents in the existing detection kits are easily stored after use, which may affect the effect of subsequent detection; 3. In the patent document CN216233634U, reagent bottles are stored in multiple placement slots that can provide fluorescence and color prompts, and a light source is provided by a light-transmitting extrusion structure, so that the reagent bottles can be viewed and distinguished in the test kit, which is convenient for distinguishing different reagent bottles and reduces the possibility of damage to the reagent bottles. It does not take into account that the accuracy of existing detection kits is low and the test results are easily affected by other antibodies; 4. In the patent document CN111929433B, antibody positivity can be detected earlier at a lower antibody level in the early stage, providing a basis for the clinical pig herd infection situation, but it does not take into account the problem that the existing detection kit has a poor protective effect when used.
