Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological detection technology, and in particular to a test strip box and a test card. Background Technology
[0002] Because some food products are sprayed with pesticides during cultivation, pesticide residues may remain, especially in some fruits. Therefore, food testing is necessary to ensure food safety. Colloidal gold test strips are commonly used for food testing due to their convenient ability to detect pesticide residues.
[0003] Currently, most commercially available test strips are placed on a work surface during testing. The sample is diffused through paper chromatography to obtain the test result. However, the test result is easily affected by external environmental factors. On the one hand, the test result is related to whether the work surface is level; on the other hand, if the work surface is not clean, the test strip is easily contaminated. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a test strip box and a test card. By providing an opening in the test strip box, it is easy to apply the sample to be tested onto the test strip through the opening. The test strip can be used for testing while still in the test strip box, preventing the test strip from being contaminated by the external environment. A raised part is provided in the test strip box away from the opening, which facilitates chromatography of the test strip inside the test strip box during testing. Liquid does not flow directly onto the detection membrane surface of the test strip, resulting in more accurate test results.
[0005] Therefore, the primary objective of this utility model is to provide a test strip box and a test card.
[0006] The second objective of this invention is to provide a detection card.
[0007] To achieve the first objective of this utility model, the technical solution of this utility model provides a test strip box. The test strip box has an opening and a receiving space for accommodating test strips. The test strip box includes a raised part, which is located at a position away from the opening of the test strip box body, so that the horizontal position of the end of the test strip box body away from the opening is higher than the opening.
[0008] In one technical solution of this utility model, the raised part is a plate-shaped part formed by extending outward from the bottom of the test paper box body away from the opening.
[0009] In one technical solution of this utility model, the test strip box includes: a cover and a base plate; the distance between the top of the cover near the opening and the base plate is d1; the distance between the top of the cover away from the opening and the base plate is d2; wherein, d1>d2.
[0010] In one technical solution of this utility model, the test strip box includes: a first limiting part, which is formed by the outer wall of the cover being recessed into the receiving space.
[0011] In one technical solution of this utility model, the test strip box includes: a sample feeding part, which is a plate-shaped part formed by extending outward from the bottom of the test strip box body near the opening.
[0012] In one technical solution of this utility model, a second limiting part is provided at the end of the sample feeding part away from the opening. The second limiting part is located at the position of the sample feeding part body away from the opening, and the second limiting part is formed by the sample feeding part body protruding upward away from the sample feeding part body.
[0013] In one technical solution of this utility model, a first foldable part is provided at the end of the sample feeding part away from the opening, and the first foldable part is used to limit the test paper.
[0014] In one technical solution of this utility model, a second foldable part and a third foldable part are symmetrically arranged on both sides of the sample feeding part along the axial direction, and the second foldable part and the third foldable part are triangular in shape.
[0015] To achieve the second objective of this utility model, the technical solution of this utility model provides a test card, which includes: a test strip box as described in any of the above technical solutions; and a test strip, which is disposed in the receiving space.

[0024] The following reference Figures 1 to 9 The technical solutions of some embodiments of this utility model are described below.
[0025] An embodiment of this utility model provides a test strip box, such as Figures 1 to 6 As shown, the test strip box 100 has an opening 100a1 and a receiving space 100a2. The receiving space 100a2 is used to receive the test strip 200. The test strip box 100 includes a lifting part 110, which is located at a position away from the opening 100a1 on the body of the test strip box 100, so that the horizontal position of the end of the test strip box 100 body away from the opening 100a1 is higher than the opening 100a1.
[0026] For example, the test strip box 100 is made of transparent material, making it easy for users to observe the test results.
[0027] The test strip 200 is placed entirely within the containment space 100a2, and the sample is applied only through the opening 100a1 without contacting the workbench surface. This physically isolates the test strip from contaminants such as dust, stains, and residual reagents on the workbench, preventing contamination from affecting the accuracy of the test results. It is especially suitable for scenarios with high cleanliness requirements, such as clinical testing and food testing. The raised section 110 creates a fixed tilt angle in the test strip box, with one end of the opening 100a1 lower than the other. Regardless of whether the operating table is level, the chromatographic diffusion path of the test strip 200 within the box remains consistent, avoiding uneven sample diffusion speed and band shift caused by table tilt. This significantly reduces environmental interference with test results and improves the repeatability and comparability of test results in different scenarios. It simplifies the operation process, reduces labor costs and operational barriers, eliminating the need to clean the operating table or adjust its level beforehand. Users simply place the test strip 200 into the test strip box 100 and add the sample through the opening 100a1 to complete the test. This is particularly suitable for non-professional scenarios such as primary healthcare institutions and home self-testing, reducing result errors caused by improper operation and improving testing efficiency. The storage space 100a2 serves both as a support during testing and as a daily storage chamber, eliminating the need for additional packaging. The opening 100a1 can be designed as a sealable structure to further reduce the risk of moisture during storage, achieving integrated storage and testing and enhancing product practicality.
[0028] In some embodiments of this application, such as Figure 1 As shown, the raised part 110 is a plate-shaped extension formed by extending the bottom of the test paper box 100 body away from the opening 100a1.
[0029] For example, the test strip box 100 body and the lifting part 110 are designed as a single unit. No additional mold design is required. It can be formed with the test strip box 100 body through a single injection molding process, simplifying the production process and the number of parts, and reducing mold development, material procurement and assembly costs. It avoids the height deviation caused by the assembly gap of the separate lifting part 110, ensuring that the lifting height of each batch of products is consistent, and improving the product dimensional accuracy and the consistency of test results.
[0030] For example, the test strip box 100 is made of a foldable material, which can be bent by the user applying slight force to the extended plate-like structure.
[0031] For example, the elongated plate-like structure is marked with graduations to indicate the length.
[0032] For example, the raised section 110 is foldable. The raised section 110 creates a gap between the bottom of the test strip box 110 and the operating table. This reduces the impact of temperature conduction from the operating table on the reaction of the test strip 200, and also makes it easier for the user to move the box by holding the raised section 110, thus improving operational flexibility. Compared to point-shaped or column-shaped structures, plate-shaped structures have a larger supporting contact area, a higher degree of fit with the worktable, are less prone to shaking or shifting, have better anti-slip effects, and are more stable.
[0033] In some embodiments of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the test strip box 100 includes: a cover 120 and a base plate 130; the distance between the top of the cover 120 near the opening 100a1 and the base plate 130 is d1; the distance between the top of the cover 120 away from the opening 100a1 and the base plate 130 is d2; wherein, d1>d2.
[0034] Because the smaller the gap, the easier it is for the sample to be adsorbed onto the cover 120 due to capillary action. The larger gap between the cover 120 and the base plate 130 at one end of the opening 100a1 and the smaller gap at the other end creates a gradually narrowing, wider-at-the-front, narrower-at-the-back accommodating space 100a2. This effectively prevents obstruction of the sample's diffusion path, further improving the accuracy of the test results. It also provides users with more room to add the sample. The smaller gap d2 at the closed end creates a slight clamping force on the end of the test strip furthest from the opening. Combined with the larger gap d1 at the open end, this allows the test strip to be in a state of being fixed at one end and loose at the other within the accommodating space. This avoids the test strip 200 shaking during testing due to excessive overall gaps, while also ensuring sufficient contact between the test strip 200 at the opening 100a1 end and the sample, ensuring that the test strip 200 is always in the preset testing posture.
[0035] In some embodiments of this application, such as Figure 1 As shown, the test strip box 100 includes a first limiting part 150, which is formed by the outer wall of the cover 120 recessed into the receiving space 100a2.
[0036] For example, the first limiting portion 150 has a smoothly transitioning concave dot. This achieves anti-slip properties without damaging the test strip 200.
[0037] The first limiting part 150 can directly form physical contact with the edge or surface of the test strip 200 to achieve anti-slip limiting. The recessed first limiting part 150 has a concealed structure and does not occupy the effective area of the accommodating space 100a2. It will not affect the normal placement of the test strip 200, nor will it obstruct the diffusion path of the sample to be tested. This makes the internal structure of the test strip box 100 more compact, improves space utilization, reduces the amount of material used, and is easier to process.
[0038] In some embodiments of this application, such as Figure 1 , Figure 7 and Figure 8As shown, the test strip box 100 includes a sample feeding section 140, which is a plate-shaped section formed by extending outward from the bottom of the test strip box 100 body near the opening 100a1.
[0039] For example, a fixing part is provided on the cover 120, which can cooperate with the sample feeding part 140 to close the opening 100a1.
[0040] For example, the sample feeding part 140 can be integrally formed with the cover 120, the base plate 130, and the lifting part 110 through a single injection molding process.
[0041] Specifically, the sample dispensing section 140 is designed to prevent the test strip 200 from directly contacting the work surface. The sample dispensing section 140 can also serve as a receiving tray. If the sample to be tested overflows during operation, the overflowing sample will drip onto the extended plate-like surface instead of directly contacting the test strip box 100 or the work surface. This prevents the overflowing sample from penetrating into the test strip box 100 and contaminating the test strip 200, and also prevents the sample from contaminating the work surface and then back-contaminating the test strip 200 used in subsequent tests, thus ensuring the cleanliness of the testing environment.
[0042] In some embodiments of this application, such as Figure 1 As shown, a second limiting part 141 is provided at the end of the sample feeding part 140 away from the opening 100a1. The second limiting part 141 is provided at the position of the sample feeding part 140 body away from the opening 100a1. The second limiting part 141 is formed by the sample feeding part 140 body protruding upward away from the sample feeding part 140 body.
[0043] When the test strip 200 tends to slide outward due to its tilted posture or the impact force of sample application, the second limiting part 141 forms a physical block to prevent the test strip 200 from sliding out or shifting, which would cause sample misalignment.
[0044] In some embodiments of this application, such as Figure 7 As shown, a first foldable portion 142 is provided at the end of the sample feeding part 140 away from the opening 100a1. The first foldable portion 142 is used to limit the test paper 200.
[0045] For example, the easy-folding function is achieved by pre-setting creases in the mold design.
[0046] For example, the first foldable portion 142 can be folded downwards to prevent the test strip 200 from contacting a dirty surface. For example, the first foldable part 142 can be folded upward to form a blocking structure to prevent the test paper 200 from slipping out or shifting, which would cause sample misalignment.
[0047] In some embodiments of this application, such as Figure 8As shown, a second easily foldable part 143 and a third easily foldable part 144 are symmetrically arranged on both sides of the sample feeding part 140 along the axial direction, and the second easily foldable part 143 and the third easily foldable part 144 are triangular in shape.
[0048] For example, the second foldable portion 143 and the third foldable portion 144 are provided at the end of the sample feeding portion 140 away from the opening 100a1.
[0049] When the second folding section 143 and the third folding section 144 are not folded, the test strip box 100 has a neat appearance; when folded, it fully surrounds and limits the test strip 200, forming a natural wedge-shaped clamping space. The user operation is simple; it further avoids the test strip 200 from sliding or shifting, ensuring the accuracy of the test.
[0050] An embodiment of this utility model provides a detection card, such as... Figure 9 As shown, the test card includes: a test strip box 100 as described in any of the above embodiments; and a test strip 200 disposed within the receiving space 100a2.
[0051] For example, a test kit 100 can only hold one test strip 200. A conventional test kit can hold dozens of test strips, which is inconvenient to carry; secondly, when taking out a test strip, the remaining test strips in the kit are easily contaminated.
[0052] For example, the test cards can be arranged in a row, and each test strip box 100 has a detachable dotted line to facilitate users to take out a specific number of test cards as needed.
[0053] The test card in this embodiment includes the test strip box 100 of any of the above embodiments, and therefore has all the beneficial effects of the test strip box 100 of any embodiment of the present utility model, which will not be repeated here.
[0054] In some embodiments of this application, the test strip 200 includes, from top to bottom, a sample pad, an NC film, and a bottom edge; wherein, at least the surface of the sample pad is coated with a colloidal gold layer; the NC film is provided with detection lines and control lines that are parallel to the bottom edge and spaced apart from each other, and the number of detection lines is one or more.
[0055] For example, there are 6 detection lines, which can detect 6 types of analytes.
[0056] The sample pad has at least one surface coated with a colloidal gold layer, which makes the chromatography of the sample easier.
[0057] 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 exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
