Technical Field

[0001] This utility model relates to the field of detection kit technology, and in particular to an influenza virus antigen detection kit. Background Technology

[0002] Influenza virus antigen test kits are commonly used tools for the rapid detection of influenza virus antigens in human samples, providing support for the early diagnosis and prevention of influenza.

[0003] A patent document with publication number CN221993477U discloses an influenza virus antigen detection kit. This kit uses two detection slots to hold different detection strips, enabling a single test card to detect two viruses. At the same time, the waterproof layer and the coating layer enhance the waterproofness and aesthetics of the reagent box.

[0004] However, in actual use, the aforementioned influenza virus antigen test kits have several drawbacks. Because the sample slots lack a dedicated sealing structure, dust, moisture, or contaminants in the air can easily penetrate the interior through the sample wells when not in use, causing the test strips to become damp, deteriorate, or become contaminated, thus affecting the accuracy of the test results. After use, the virus-containing samples remaining in the sample wells are directly exposed to the external environment, and accidental contact by personnel or airflow disturbances may cause the virus to spread, posing significant biosafety risks.

[0005] Therefore, an influenza virus antigen detection kit is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an influenza virus antigen detection kit to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include: An influenza virus antigen detection kit includes a packaging component, the inner cavity of which, from top to bottom, is provided with a storage component and test cards. Multiple test cards are provided within the inner cavity of the packaging component, and each test card is individually contained in a sealed bag. The test card includes a housing, in which a first test reagent strip and a second test reagent strip are embedded. The housing has two sample holes, and the first and second test reagent strips are respectively arranged corresponding to the two sample holes. A sealing element for sealing the sample holes is movably provided on the housing. The sealing element includes a cover plate that can cover the sample hole.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-5This utility model provides an influenza virus antigen detection kit, including a packaging component 100, a storage component 200, and test cards 300. The storage component 200 and test cards 300 are arranged sequentially from top to bottom in the inner cavity of the packaging component 100, and multiple test cards 300 are provided in the inner cavity of the packaging component 100. Each test card 300 is individually contained in a sealed bag. The test card 300 includes a shell 310, and a first test strip 320 and a second test strip 330 are embedded in the inner cavity of the shell 310. The shell 310 has two sample holes, and the first test strip 320 and the second test strip 330 are respectively connected to two samples. The housing 310 is equipped with a corresponding sealing element 340 for sealing the sample wells. The sealing element 340 includes a cover plate 341 that covers the sample wells. Two sealing plugs 342 are fixedly connected to one side of the cover plate 341. The sealing plugs 342 are arranged in a one-to-one correspondence with the sample wells and are interference-fitted with the corresponding sample wells. The layered structure avoids interference between the auxiliary components and the test card 300. The dual test strips retain the dual virus detection function. The sealing element 340 directly seals the sample wells, blocking the spread of viruses and external contamination. The separate sealing bag further provides independent protection for the unused test card 300, providing dual protection for biosafety and test strip stability.

[0022] It should be noted that the working principles of the first test strip 320 and the second test strip 330 are the same as those of the first and second test strips in an influenza virus antigen detection kit disclosed in the existing publication number CN221993477U. When the sample is contaminated with the first test strip, wait for several minutes to ten minutes to allow the virus particles to bind with the antibodies in the colloidal gold reagent. Then observe the changes in the recognition line on the first test strip. If the sample contains influenza A virus, the recognition line at line A on the first test strip will be visible. If the sample contains influenza B virus, the recognition line at line B on the first test strip will be visible. If both viruses are present, both lines A and B will show the corresponding results. At the same time, when the sample is contaminated with the second test strip, wait for several minutes to ten minutes to allow the virus particles to bind with the antibodies in the colloidal gold reagent. Then observe the changes in the recognition line on the second test strip. If the sample contains group A streptococcal antibodies, the recognition line at line T on the second test strip will be visible.

[0023] The housing 310 has a groove 311 on one side. One end of the cover plate 341 is rotatably connected to the inner cavity of the groove 311 via a rotating shaft. The other end of the cover plate 341 is detachably connected to the housing 310 via a snap-fit ​​connector. The groove 311 provides a stable fulcrum for the cover plate 341, ensuring a fixed opening and closing path and preventing the cover plate 341 from shifting. The detachable snap-fit ​​design ensures the sealing reliability of the cover plate 341 when closed and facilitates quick opening of the sample hole during use.

[0024] The snap-fit ​​component includes a slot 312 formed on the housing 310 and positioned opposite to the groove 311. A buckle 343 is integrally formed on the cover plate 341 to cooperate with the slot 312. The buckle 343 and the sealing plug 342 are both located on the same side of the cover plate 341. The buckle 343 snaps into the inner cavity of the slot 312. The cooperation between the buckle 343 and the slot 312 allows the cover plate 341 to fit tightly against the housing 310, thereby squeezing the sealing plug 342 and the sample hole to form a more reliable interference seal, preventing the cover plate 341 from loosening during transportation and causing the seal to fail. The same-side design ensures that the sealing force and the snap-fit ​​force are in the same direction, improving the overall sealing stability.

[0025] Among them, the end of the cover plate 341 near the buckle 343 is integrally formed with a lug 344. There are two lugs 344 symmetrically arranged about the center of the cover plate 341. The thickness of the lug 344 is less than the thickness of the cover plate 341. The lug 344 provides a clear leverage point for opening the cover plate 341. Users can easily open the cover plate 341 by pressing the lug 344 with their fingertips, solving the problem of difficulty in applying force to open it when there is no lug 344.

[0026] The packaging component 100 includes a cardboard box 110. Two symmetrically arranged support plates 120 are fixedly connected to the inner cavity of the cardboard box 110, forming a receiving cavity between the two support plates 120. The storage component 200 and the test card 300 are respectively placed in the upper and lower parts of the receiving cavity. Each support plate 120 and the side wall of the cardboard box 110 form a first storage cavity. The two first storage cavities are used to separately store the instruction manual and the biosafety bag. The support plate 120 not only separates and forms the receiving cavity for placing the storage component 200 and the test card 300, but also constructs the first storage cavity to realize the classified storage of the instruction manual and the biosafety bag, so that they can be retrieved without searching. At the same time, the support plate 120 can enhance the overall structural strength of the cardboard box 110 and prevent the side wall of the cardboard box 110 from deforming and squeezing the internal structure.

[0027] The bottom of the receiving cavity is fixedly connected to multiple equally spaced partitions 130. Multiple test cards 300 are spaced apart from the partitions 130, and the height of the partitions 130 is lower than the height of the test cards 300. The partitions 130 independently separate the multiple test cards 300 to prevent the test cards 300 from squeezing or colliding with each other during transportation or carrying, and to prevent the housing 310 from deforming or the test strips from shifting. The height of the partitions 130 is lower than that of the test cards 300, so as not to hinder the operation of taking out and putting in the test cards 300, thus taking into account both protection and practicality.

[0028] The storage component 200 includes a tray 210 placed on top of the receiving cavity with an open top. A partition 220 is fixedly connected to the inner cavity of the tray 210, which divides the inner cavity of the tray 210 into two second storage chambers for storing sampling swabs and eluent tubes separately. The tray 210 centrally stores the sampling swabs and eluent tubes, preventing auxiliary components from scattering. The partition 220 divides the tray 210 into two independent chambers, enabling the separate storage of the two types of components and making them intuitive and convenient to use. The open design facilitates quick access to components and is suitable for emergency testing scenarios.

[0029] The pallet 210 has side plates 230 integrally formed on both sides. The side plates 230 are arranged in a one-to-one correspondence with the support plates 120, and the side plates 230 overlap the top of the corresponding support plates 120. The side plates 230 overlap the top of the support plates 120 to provide stable support for the pallet 210 and prevent the pallet 210 from shaking and shifting in the receiving cavity. The overlapping structure allows the pallet 210 to be taken out directly upward without disassembling other parts, thus improving operating efficiency.

[0030] Finger grooves 400 are provided in the middle of the side panel 230 away from the tray 210 and in the center of the top of the front side of the cardboard box 110. The finger grooves 400 are semi-circular in structure. The semi-circular finger grooves 400 fit the shape of the fingertip, and the user can easily grab the tray 210 or open the cardboard box 110 through the finger grooves, which is suitable for one-handed operation and reduces the difficulty of operation.

[0031] The front side of the cardboard box 110 is fixedly connected to a transparent observation window 500. The length of the transparent observation window 500 is adapted to the spacing between the two support plates 120. The transparent observation window 500 allows direct observation of the remaining quantity of test cards 300 in the storage cavity, enabling inventory confirmation without opening the box and reducing the risk of internal components getting damp due to frequent opening. The length of the transparent observation window 500 is adapted to the spacing between the support plates 120, ensuring coverage of the entire storage area of ​​the test cards 300 with no blind spots, facilitating usage planning.

[0032] The working principle of this utility model is as follows: Reagent kit 110 opening and component confirmation: The user opens the cardboard box 110 by using the semi-circular finger groove 500 on the front side of the cardboard box 110 and directly views the number of remaining test cards 300 in the receiving cavity through the transparent observation window 500. Inventory confirmation can be completed without fully opening the box. Then, the user uses the finger groove 500 on the side panel 230 of the tray 210 to fasten the side panel 230 and remove the tray 210 from the top of the receiving cavity. Auxiliary component retrieval and sample pretreatment: Take out the sampling swab and elution tube from the two second storage cavities separated by the partition 220 in the tray 210 respectively; take out the instruction manual from the first storage cavity formed by the support plate 120 and the side wall of the cardboard box 110, use the sampling swab to collect human samples (such as nasopharyngeal swabs) according to the steps in the instruction manual, and put the collected swab into the elution tube to complete the sample elution and obtain the sample to be tested; Test card 300 preparation and sample addition: Take out a test card 300 in a sealed bag from the gap 130 at the bottom of the receiving cavity and tear open the sealed bag; use the symmetrical lugs 344 at the end of the cover plate 341 to fasten the cover plate 341, so that the cover plate 341 rotates around the groove 311 of the housing 310 as a fulcrum until the buckle 343 disengages from the slot 312, open the cover plate 341 and expose two sample holes; add the eluted sample to be tested into the two sample holes respectively, so that the sample is in full contact with the corresponding first test strip 320 and second test strip 330; Detection reaction and result reading: Wait for the detection reaction to complete (refer to the reaction time indicated in the instruction manual), and keep the cover 341 open during this period to ensure that the test strip and the sample react normally; after the reaction is completed, observe the display of the recognition lines on the first test strip 320 and the second test strip 330 to determine whether the corresponding influenza virus antigen is present in the sample; Waste disposal and storage: After the test is completed, close the cover plate 341 so that the buckle 343 is engaged in the slot 312 and the sealing plug 342 is inserted into the sample hole to complete the seal. Then, put the used sampling swab, eluent tube and test card 300 into the biosafety bag taken from the first storage chamber, seal it and dispose of it in accordance with medical waste regulations. Unused test card 300, sampling swab and eluent tube are put back into the original chamber (test card 300 is put back into the gap of partition 130, auxiliary parts are put back into tray 210), and the tray 210 is attached back to the top of the support plate 120. Finally, close the paper box lid of the paper box 110 to complete the overall storage.
