Description

Technical Field

[0001] This utility model relates to the field of test strip technology, specifically an abamectin rapid test strip. Background Technology

[0002] Abamectin, a novel 16-membered macrocyclic lactone insecticide, is produced by fermentation of Streptomyces avermitosa. Due to its novel chemical structure, unique mechanism of action (interfering with the neurophysiological activity of insects, stimulating the release of γ-aminobutyric acid, thereby inhibiting nerve conduction in arthropods), strong insecticidal activity, and characteristics such as broad spectrum, high efficiency, long-lasting effect, and relative safety, it meets the requirements of modern ecological pesticides and is widely used for the control of various nematodes, arthropod parasites, and insects, both internally and externally.

[0003] Therefore, the detection of avermectin residues in food and tableware products has become a key monitoring indicator, and avermectin residue detection methods have also become a key research area. Currently, the main methods for avermectin residue detection are chromatographic and immunoassay methods. Chromatographic methods include thin-layer chromatography (TLC), liquid chromatography (LC), and liquid chromatography-mass spectrometry (LC-MS). These methods have drawbacks such as complex sample pretreatment, the need for specialized operators, and the requirement for expensive instruments, and are often used for confirmatory analysis of avermectin residues. Extensive research has been conducted on avermectin detection, including kits for avermectin detection, kit preparation methods, and methods for using kits to detect avermectin. However, the commonly used methods for avermectin detection in existing technologies include: thin-layer chromatography (TLC), gas chromatography (GC), high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC / MS), liquid chromatography-mass spectrometry (HPLC / MS), and capillary electrophoresis (CE). The above-mentioned detection methods have drawbacks such as complex equipment, cumbersome sample pretreatment and measurement operations, making them unsuitable for on-site monitoring and large-scale sample screening. Moreover, their high cost limits their widespread use.

[0004] Avermectin rapid test strips are a simple, rapid, and economical immunoassay method developed by integrating modern monoclonal antibody technology and new materials technology with colloidal gold immunochromatography. This test strip is simpler, faster, and easier to interpret than enzyme-linked immunosorbent assay (ELISA). It is a new, economical, and environmentally friendly technology for detecting avermectin. However, existing avermectin rapid test strips do not allow users to perform multiple tests simultaneously or to conduct control tests to improve the accuracy of the test results. Utility Model Content

[0005] To address the problem of inconvenience in simultaneously performing multiple avermectin tests in the prior art, this invention proposes a rapid avermectin test strip.

[0006] The technical solution of this utility model is as follows: the avermectin rapid test strip includes a placement plate, and multiple sets of fixing strips are fixedly installed on the upper surface of the placement plate. Each set of fixing strips has two fixing strips, and each of the two fixing strips in each set has a connecting strip glued to it for installing the test strip. Each test strip has a baffle fixedly installed on both sides, and the baffle is used to separate two adjacent test strips.

[0007] Preferably, the bottom of the connecting strip is coated with an adhesive layer for connecting the fixing strip.

[0008] Preferably, the test strip includes a base plate, on which a sample pad, a reaction pad, and an absorbent pad are mounted.

[0009] Preferably, one end of the sample pad has a first bend, and the bottom of the first bend is bonded to the upper surface of one end of the reaction pad.

[0010] Preferably, one end of the absorbent pad has a second bend, and the bottom of the second bend is bonded to the upper surface of the other end of the reaction pad.

[0011] Preferably, the reaction pad is provided with a detection area and a quality control area.

[0012] Preferably, the detection area is located on the side closer to the sample pad, and the quality control area is located on the side closer to the absorbent pad.

[0013] Preferably, the sample pad is a filter membrane, and the reaction pad is a nitrocellulose membrane.

[0014] Preferably, the length of the sample pad, reaction pad, and absorbent pad connected together is less than or equal to the length of the base plate.

[0015] The advantages of this invention are: by setting multiple sets of fixing strips on the placement plate to fix the test strips with connecting strips, and by setting an adhesive layer at the bottom of the connecting strips to connect the fixing strips, the ease of installation is improved. This makes it easier for users to install multiple test strips on the placement plate for multiple sets of control tests, thereby improving the accuracy of avermectin detection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, an abamectin rapid test strip includes a placement plate 1 on which multiple test strips 2 are mounted. Multiple sets of fixing strips 11 are fixedly mounted on the upper surface of the placement plate 1, with two fixing strips in each set. Connecting strips 3 are fixedly mounted at both ends of each test strip 2. The bottom of the connecting strips 3 is coated with an adhesive layer for connecting the fixing strips 11. The connecting strips 3 at both ends of each test strip 2 are fixedly connected to the two fixing strips 11 in each set through the adhesive layer, thereby mounting multiple test strips 2 on the placement plate 1 to facilitate multiple sets of controls by the user.

[0023] Each test strip 2 has a baffle 4 fixedly installed on both sides. In this embodiment, the baffle 4 is made of PVC material. The baffle 4 is used to separate two adjacent test strips 2 to prevent the samples on the two adjacent test strips 2 from contacting each other and affecting the accuracy of the experimental results.

[0024] The test strip 2 includes a base plate 21, on which a sample pad 22, a reaction pad 23, and an absorbent pad 24 are mounted. One end of the sample pad 22 has a first bend 221, the bottom of which is glued to the upper surface of one end of the reaction pad 23. One end of the absorbent pad 24 has a second bend 241, the bottom of which is glued to the upper surface of the other end of the reaction pad 23. The length of the sample pad 22, the reaction pad 23, and the absorbent pad 24 after being connected is less than or equal to the length of the base plate 21. An adhesive layer can be added to the bottom of the base plate 21 as needed. The reaction pad 23 has a detection area 231 and a quality control area 232. The detection area 231 is located on the side closer to the sample pad 22, and the quality control area 232 is located on the side closer to the absorbent pad 24. The sample pad 22 is a filter membrane, and the reaction pad 23 is a nitrocellulose membrane.

[0025] Working principle: In use, first select an appropriate number of test strips 2 as needed, and install the selected test strips 2 on the placement plate 1 through the connecting strip 3. Then, place the multiple sets of samples to be tested on the sample pads 22 of the multiple test strips 2 respectively. Under the action of the absorbent pad 24, the liquid in the sample to be tested flows from the end of the reaction pad 23 near the sample pad 22 to the end of the reaction pad 23 near the absorbent pad 24. The test results are presented through the detection area 231 and the quality control area 232 on the reaction pad 23. The multiple sets of test strips 2 placed side by side can facilitate intuitive comparison by the user, thereby reducing the detection error.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
