Abstract
Description
Technical Field
[0001] This utility model relates to the field of salmon detection technology, and in particular to a convenient and rapid salmon detection kit. Background Technology
[0002] Salmon, belonging to the genus Salmon in the family Salmonidae of the order Salmoniformes, is renowned for its delicious flavor, rich nutritional value, high content of deep-sea fish oil, and cholesterol-lowering properties. Often hailed as the "supreme fish," it is highly favored by diners. Salmon meat is firm, elastic, and has a smooth, refreshing taste, making it commonly consumed raw. However, for food safety reasons, it is necessary to test for residues of substances such as furazolidone and chloramphenicol in salmon.
[0003] Traditional detection technologies, while exhibiting excellent accuracy, require precise temperature control and a range of upstream and downstream supporting equipment, making them difficult to set up and apply outside of laboratories. This limits their application in field testing. Existing rapid test kits, functionally speaking, simply combine the reaction reagents and reaction tubes into a single box. In actual testing, after the reaction is complete, the reaction solution must be transferred to the detection tube, and then the test solution is dropped onto the test card through the detection tube. This cumbersome operation affects testing efficiency, and the exposure to the environment during the testing process can influence the results. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a convenient and easy-to-use rapid salmon test kit that allows the testing process to be visualized in a sealed environment, thus meeting the needs of rapid on-site testing.

[0008] The salmon detection component located inside the box includes several reaction tubes, a liquid outlet fixed on the corresponding reaction tube, a fastening strap fitted on the corresponding liquid outlet, and a detection cap fastened on the corresponding reaction tube.
[0009] As a further improvement to the above solution, the longitudinal cross-section of the reagent rack is stepped, and several reagent tube slots are evenly distributed on the reagent rack.
[0010] As a further improvement to the above scheme, half of the reagent tube slots are used to hold reagent tubes containing furan extractant, and the remaining half of the reagent tube slots are used to hold reagent tubes containing reconstitution solutions specifically for nitrofuran metabolites.
[0011] As a further improvement to the above solution, the salmon detection component is located on the corresponding side of the reagent rack, and the salmon detection component and the reagent rack are separated by a partition, which is fixed to the box.
[0012] As a further improvement to the above solution, the number of reaction tubes is half the number of reagent tube slots, and both the reaction tubes and the detection caps are made of plastic.
[0013] As a further improvement to the above solution, a tube cap is installed at the end of the reaction tube facing away from the liquid outlet, and a sealing element is fixedly fitted on the tube cap. The sealing element is made of rubber. A liquid outlet channel is opened in the liquid outlet.
[0014] As a further improvement to the above solution, a plug is fixedly installed at the center of the detection cover, and a test strip is placed upright inside the detection cover through the plug.
[0015] As a further improvement to the above scheme, when the detection cap is installed on the reaction tube, the liquid outlet is located inside the detection cap, and the test strip and the liquid outlet are in contact.
[0016] As a further improvement to the above solution, the salmon rapid test kit also includes an ultraviolet blocking layer, which is coated and fixed on the surface of the foam pad; the ultraviolet blocking layer is made of acrylic material.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Additional aspects and advantages of this utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. It should be understood that the following description is merely illustrative and not intended to limit the utility model.
[0027] The specific embodiments of this utility model are described in detail below.
[0028] Please see Figure 1-5 This embodiment provides a convenient and rapid salmon test kit, which includes a box body 1, a foam pad 2 fixedly installed on the inner wall of the box body 1, an ultraviolet blocking layer 3 coated and fixed on the surface of the foam pad 2, a reagent rack 4 fixedly installed inside the box body 1, and a salmon detection component located inside the box body 1. This embodiment uses the detection of furazolidone residue in salmon samples as an example. It should be noted that the kit of this embodiment can also be used to detect residues such as chloramphenicol in salmon samples. When performing the aforementioned residue detection, it is only necessary to change the corresponding extraction reagent and replace the test strip 11 with the corresponding test strip, which will not be elaborated here.
[0029] The ultraviolet blocking layer 3 is made of acrylic material. In this embodiment, the box body 1 is a cardboard box. While the foam pad 2 provides heat insulation, it also plays a role in cushioning and shock absorption to a certain extent. In conjunction with the ultraviolet blocking layer 3, it blocks ultraviolet rays, prevents the reaction reagents from denaturing, and achieves the light-proof storage of the reaction reagents.
[0030] The reagent rack 4 has a stepped cross-section, and several reagent tube slots 5 are evenly distributed on the rack 4. In this embodiment, based on the stepped reagent rack 4, the placement space is rationally planned to accommodate reagent tubes of different volumes, improving the neatness of the reagent tubes on the rack 4. Half of the reagent tube slots 5 are used to accommodate reagent tubes containing furan extract, and the remaining half are used to accommodate reagent tubes containing reconstitution solutions for nitrofuran metabolites.
[0031] The salmon detection component is located on the corresponding side of the reagent rack 4, and the salmon detection component and the reagent rack 4 are separated by a partition, which is fixed to the box body 1. The salmon detection component includes several reaction tubes 6, a liquid outlet 7 fixed on the corresponding reaction tube 6, a fastening strap 8 sleeved on the corresponding liquid outlet 7, and a detection cap 9 fastened on the corresponding reaction tube 6.
[0032] The number of reaction tubes 6 is half the number of reagent tube slots 5, and both the reaction tubes 6 and the detection caps 9 are made of plastic. In order to facilitate squeezing the reaction tubes 6 so that the solution drips onto the test strip 11, the reaction tubes 6 in this embodiment are made of PP plastic. In other embodiments, materials that are easy to squeeze, such as PE plastic, can also be used, which will not be elaborated here.
[0033] A cap is installed at the end of the reaction tube 6 facing away from the liquid outlet 7, and a sealing element made of rubber is fixedly fitted on the cap. In this embodiment, the reaction tube 6 contains a buffer solution. During detection, the cap is removed to add salmon tissue sample, furan extract, and a special reconstitution solution for nitrofuran metabolites for the reaction. To ensure a complete reaction, the cap can be replaced, and the reaction tube 6 can be inverted and shaken. The sealing element prevents the solution from leaking out along the connection between the cap and the reaction tube 6.
[0034] The liquid outlet section 7 is provided with a liquid outlet channel. In order to facilitate the control of the amount of test solution dripped onto the test strip 11, in this embodiment, the diameter of the liquid outlet channel is 0.5 cm. Based on this, the test solution is squeezed out by the squeezing action to avoid the situation where excessive squeezed out solution would interfere with the test result of the test strip 11.
[0035] In this embodiment, to prevent solution leakage during preparation, i.e., reagent reaction, a fastening band 8 is used to tighten and close the liquid outlet channel at the liquid outlet 7. The fastening band 8 used is an elastic rope, and the fastening band 8 can be removed when the solution needs to be squeezed out.
[0036] A plug 10 is fixedly installed at the center of the detection cap 9, and a test strip 11 is upright inside the detection cap 9 through the plug 10. When the detection cap 9 is installed on the reaction tube 6, the liquid outlet 7 is located inside the detection cap 9, and the test strip 11 is in contact with the liquid outlet 7. In this embodiment, by placing the test strip 11 upright in the detection cap 9, the squeezed solution can directly wet one side of the test strip 11 for reading the test result. It should be noted that the detection cap 9 in this embodiment achieves flexible assembly with the reaction tube 6 through a snap-fit method similar to a pen cap and pen sleeve, which will not be described in detail here.
[0037] The salmon rapid test kit in this embodiment is used as follows:
[0038] First, open the box lid and take out a reaction tube 6, a reagent tube containing furan extractant, and a reagent tube containing a special reconstitution solution for nitrofuran metabolites from box 1 in sequence.
[0039] Next, open the cap of reaction tube 6, add the salmon tissue sample that has been homogenized into reaction tube 6, then add furan extractant into reaction tube 6, shake for 5 minutes, then add nitrofuran metabolite reconstitution solution, continue shaking for 5 minutes, and after the reaction is complete, remove the fastening strap 8 and put on the detection cap 9.
[0040] Finally, squeeze the reaction tube 6. At this time, the solution drips out along the liquid outlet 7 and is absorbed by the test strip 11 to achieve detection.
[0041] All of the above processes are visualized, allowing for a clear view of the entire testing process and the final results.
[0042] In summary, the salmon rapid test kit of this embodiment has the following advantages: the test results can be obtained simply by adding the salmon sample and reaction reagent to the salmon test component, eliminating the inconvenience of pouring out the reaction solution and transferring it to the test tube. It can meet the needs of rapid on-site testing. The test process is simple, easy to operate, and the test process is visualized in a sealed environment, reducing the interference of the external environment on the test results.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
