Description

Technical Field

[0001] The utility model relates to the technical field of biological detection, in particular to an immunochromatographic detection kit. Background Art

[0002] For immunochromatographic strip testing, simply add the sample to the sample loading area of ​​the test strip. After a certain reaction time, the test result can be obtained by visual observation. Prepared immunochromatographic strips are generally stored in a packaging bag with silica gel desiccant.

[0003] Currently, some samples need to be diluted with diluent before testing using detection kits after sampling. For example, enzyme-linked immunosorbent assay is a highly sensitive reaction. If the serum is not diluted, it will inevitably produce a strong non-specific reaction and a false positive. Therefore, it is necessary to use diluent to dilute the sample by a specific multiple to reduce the non-specific reaction and allow the specific antigen-antibody reaction to be fully reflected.

[0004] For example, an immunochromatographic saliva detection kit disclosed in Chinese patent publication number CN219369765U includes a detection box body, a U-shaped frame is fixedly connected to one side of the interior of the detection box body, and a diaphragm is fixedly connected to the middle of the U-shaped frame, which divides the detection box body into a reagent dilution chamber and a reagent detection chamber. The top of the detection box body is connected to a top cover, and the top of the top cover is connected to a rectangular through opening. The bottom wall of the reagent detection chamber is provided with a detection reagent strip. The utility model divides the detection box body into a reagent dilution chamber and a reagent detection chamber by the provided U-shaped frame and diaphragm. The patient can directly introduce saliva into the rectangular through opening, and the saliva enters the reagent dilution chamber to facilitate the dilution of the saliva. After the dilution is completed, the driving structure is used to push the diluted saliva into the reagent detection chamber, so that the diluted saliva is displayed as negative or positive on the detection reagent strip to display the test results, thereby reducing the contact between the virus and medical staff.

[0005] During actual use of the above device, the driving rod does not have a limiting structure. Since the test kit usually has an outer packaging, the user may easily accidentally rotate the driving rod and puncture the diaphragm when the outer packaging is not opened, affecting the detection and wasting resources. Therefore, this needs to be improved. Utility Model Content

[0006] The purpose of the utility model is to provide an immunochromatographic detection kit, which has the function of limiting the insertion rod, so as to avoid the insertion rod from being accidentally pushed to puncture the diaphragm when the detection box body is not in use, thereby affecting the detection and causing waste of resources, and can also increase the accuracy of the detection.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an immunochromatographic detection kit, comprising a detection box body, a diaphragm installed inside the detection box body, a through opening connected to the left end of the upper end surface of the detection box body, a transparent plate located on the right side of the diaphragm installed through the upper end surface of the detection box body, a detection reagent strip located on the right side of the diaphragm installed on the inner bottom end surface of the detection box body, a sealing plug installed at the end of the through opening, a connecting belt installed between the outer side wall of the sealing plug and the left end of the upper end surface of the detection box body, and a butyl rubber plug installed through and fixedly installed on the bottom of the left side wall of the detection box body;

[0008] A fixed frame is installed on the left side wall of the detection box body, a screw rod is movably installed through the left side wall of the fixed frame, and a plug rod opposite to the position of the butyl rubber plug is installed on the right end of the screw rod;

[0009] The outer side wall of the screw rod is provided with a limiting hole, the front end surface of the fixing frame passes through a bolt hole opposite to the limiting hole, a bolt is installed inside the bolt hole, and one end of the bolt extends into the inside of the limiting hole.

[0010] In order to facilitate the insertion of the insertion rod into the butyl rubber stopper, as a preferred immunochromatographic detection kit of the present invention, a pointed cone is installed at the right end of the insertion rod.

[0011] In order to facilitate sealing the opening, as an immunochromatographic detection kit of the present invention, preferably, the sealing plug is made of rubber.

[0012] In order to facilitate the rotation of the screw, as a preferred embodiment of the immunochromatographic detection kit of the present invention, a hand wheel is installed at the left end of the screw.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] First, in the initial state, the bolt can limit the screw rod, preventing the staff from accidentally turning the screw rod before opening the packaging of the test box, causing the rod to penetrate the butyl rubber plug and puncture the diaphragm, affecting the test and causing waste of resources;

[0015] When using this device, the staff opens the opening through the sealing plug, then drips the sample into or directly introduces it into the test box body, and then covers the sealing plug on the port of the opening. At this time, the staff can pick up the test box body and shake the test box body to allow the diluent to fully dilute the sample. Then, by unscrewing the bolt and then turning the screw, the insertion rod can be pushed to move, so that the insertion rod is inserted into the butyl rubber plug and puncture the diaphragm. At this time, the diluent contacts the test reagent strip, so that the test reagent strip detects the sample diluent, thereby increasing the accuracy of the test. BRIEF DESCRIPTION OF THE DRAWINGS
