Description

Technical Field

[0001] This utility model relates to the field of home-use gastric pylorus screening technology, and in particular, to a gastric pylorus detection card. Background Technology

[0002] Helicobacter pylori (Hp) infection is a significant contributing factor to various gastric diseases, and convenient and effective preliminary screening is crucial for improving public health. In recent years, Hp antibody test strips based on immunochromatography have been increasingly used for home testing. These strips typically collect a blood sample from a fingertip and use colloidal gold labeling technology to detect Hp-specific antibodies. They offer advantages such as ease of use, rapid results, and non-invasiveness, making them suitable for preliminary screening in the home.

[0003] Among existing home-use Helicobacter pylori screening products, test cards using the dry chemistry method based on dental plaque sampling have seen some application. However, these test cards are typically designed for single-use testing, with the test card and sampling swab usually packaged separately. Users need to unpack and combine them separately, making the process cumbersome. Furthermore, the testing steps require repeated reading of the instruction manual, resulting in inconvenience and a poor user experience. During the testing process, the separate components and unintuitive operation steps may introduce human error, negatively impacting the accuracy of the test results.

[0004] Current technologies lack a highly integrated, easy-to-operate, and reusable gastric pylorus detection card structure, making it difficult to simultaneously meet home users' higher demands for testing convenience, result reliability, and user experience. Therefore, it is necessary to improve the structure of existing gastric pylorus detection cards to overcome the aforementioned shortcomings. Utility Model Content

[0005] This invention provides a gastric pylorus detection card that can perform multiple tests at once, and the reliability of test results can be improved through retesting. At the same time, the top cover has only one test hole, and the sliding key can switch between multiple settings to align one of the test strips with the test hole, which reduces the time that the untested strips are fully exposed to the air and improves the convenience of use. This solves the technical problems of existing home-use gastric pylorus screening products, which are complicated to operate and have low test accuracy.

[0006] This utility model provides a gastric pylorus detection card, including an outer shell and a slide key. The surface of the outer shell has a control hole and a test hole. The slide key is slidably arranged in the inner cavity of the outer shell. The slide key is provided with a push rod and a test strip storage slot. A gastric pylorus test strip is fixedly arranged in the test strip storage slot. There are multiple test strip storage slots, and the arrangement direction of the multiple test strip storage slots is consistent with the length direction of the control hole. The push rod of the slide key is exposed through the control hole, and the arrangement position of the test strip storage slot matches the test hole. By pushing the push rod to move in the control hole, the slide key is driven to slide in the outer shell, thereby realizing that different test strip storage slots and test holes are vertically aligned.

[0007] Furthermore, the test strip reservoir is provided with a test strip slot for securing the gastric pylorus test strip; and / or a flexible block is provided between two adjacent test strip reservoirs; and / or a flexible block is provided on the side of the test hole facing the test strip reservoir.

[0008] Furthermore, a stop mechanism is provided between the slide key and the outer shell. The stop mechanism includes a stop lever and a stop slot. The number and spacing of the stop slots are matched with the test strip reservoir. By sliding the slide key in the inner cavity of the outer shell, the stop lever is moved into one of the stop slots, thereby making the test strip reservoir corresponding to the stop slot vertically aligned with the test hole. Alternatively, the number and spacing of the stop levers are matched with the test strip reservoir. By sliding the slide key in the inner cavity of the outer shell, the stop slot is locked outside one of the stop levers, thereby making the test strip reservoir corresponding to the stop lever vertically aligned with the test hole.

[0009] Furthermore, at least one end of the outer shell is provided with a pull-out opening, and the drawer is slidably assembled into the outer shell through the pull-out opening. At least one sampling swab is placed in the drawer slot. After the drawer slides into the inner cavity of the outer shell, the pull-out opening is closed by the end plate of the drawer.

[0010] Furthermore, sliding guide rails are provided on both sides of the bottom of the drawer.

[0011] Furthermore, the bottom of the drawer is equipped with a push-out opening, through which the sampling swab is pushed to facilitate removal of the sampling swab from the drawer; and / or the bottom of the drawer is also equipped with a finger stop, which protrudes outside the outer shell when the drawer is fully slid into the inner cavity of the outer shell, and applying force to the finger stop allows the drawer to slide out when fully slid into the inner cavity of the outer shell; and / or the bottom of the drawer is also equipped with a latch, which cooperates with the limiting component on the inner wall of the outer shell to ensure that the drawer slids into the inner cavity of the outer shell and ensures the relative positioning between the drawer and the outer shell; and / or the rear end of the drawer is also equipped with a rear stop, which is used to limit the drawer when it is pulled out by cooperating with the limiting component on the inner wall of the outer shell to prevent the drawer from falling out.

[0012] Furthermore, the inner wall of the outer casing is also provided with multiple anti-tilting limiting structures, which are arranged at intervals along the direction of drawer movement to prevent the drawer from tilting up and down when it slides out.

[0013] Furthermore, the inner walls of the outer casing are provided with first guide ribs on both sides, which are used to cooperate with the side surfaces of the slide key to achieve directional sliding of the slide key; and / or the inner walls of the outer casing are provided with second guide ribs on both sides, which are used to cooperate with the side surfaces of the drawer to achieve directional sliding of the drawer.

[0014] Furthermore, the outer casing includes an upper cover and a lower cover. The lower cover is groove-shaped, and the upper cover is plate-shaped. The upper cover fits into the snap-fit ​​groove of the lower cover and is positioned by interlocking with each other via positioning posts. Multiple sets of positioning posts are arranged at intervals along the edge of the lower cover.

[0015] Furthermore, the upper cover surface and / or the lower cover surface are provided with marking areas, which are used to indicate the area functions and usage methods.

[0016] This utility model has the following beneficial effects: 1. Achieved integrated and multiple testing functions: By setting a sliding key with multiple independent test strip storage slots in the inner cavity of the outer shell, multiple test units are highly integrated into one device, changing the existing home testing cards that are mostly single-test. This allows users to perform repeated tests or comparative verifications without opening multiple independent packages, significantly improving the integration and ease of use of the device.

[0017] 2. Improved ease of operation and user experience: The push rod on the slide key is exposed through the control hole, providing users with a clear and direct operating component. Different test units can be switched by simple linear sliding operation, simplifying the operation steps and avoiding tedious processes such as repeatedly unpacking and finding the sampling hole, making the testing process more intuitive and user-friendly.

[0018] 3. Ensures the standardization of the testing process and the consistency of results: Each test strip reservoir is fixedly equipped with a gastric pylorus test strip, and its position matches the test hole on the outer shell. This ensures that when the slide key is slid to a specific position, the gastric pylorus test strip can be precisely aligned with the test hole, providing a standardized and consistent sample addition and observation window for each test. This helps reduce errors caused by deviations in the operation position or movement of the gastric pylorus test strip, thereby improving the reliability and consistency of the test results.

[0019] 4. Reduced risk of contamination and operational errors: The separate packaging of test cards and sampling swabs is a common source of contamination and operational errors in existing technologies. This invention embeds and encapsulates the sampling swabs within the inner cavity of the outer shell, and places multiple pyloric test strips separately inside the test card. This eliminates the need for manual installation or removal by the user before testing, effectively reducing the possibility of contamination or damage during operation. From a physical structure perspective, it ensures the purity of the test samples and the hygiene and safety of the testing process.

[0020] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the gastric pylorus detection card of this embodiment includes a housing 100 and a slide key 200. The surface of the housing 100 is provided with a control hole 101 and a test hole 102. The slide key 200 is slidably arranged in the inner cavity of the housing 100. The slide key 200 is provided with a push rod 201 and a test strip storage slot 202. A gastric pylorus test strip 203 is fixedly arranged in the test strip storage slot 202. Multiple test strip storage slots 202 are provided, and the arrangement direction of the multiple test strip storage slots 202 is consistent with the length direction of the control hole 101. The push rod 201 of the slide key 200 is exposed through the control hole 101, and the arrangement position of the test strip storage slots 202 matches the test hole 102. By pushing the push rod 201 to move in the control hole 101, the slide key 200 is driven to slide in the housing 100, thereby realizing that different test strip storage slots 202 and test holes 102 are vertically aligned. This utility model of a gastric pylorus detection card integrates multiple testing units into a single device by incorporating a slide key 200 with multiple independent test strip storage slots 202 within the inner cavity of the outer casing. This changes the existing single-test mode of most home testing cards, allowing users to perform repeated tests or comparative verifications without unpacking multiple individual packages, significantly improving the device's integration and ease of use. The push rod 201 on the slide key 200 is exposed through a control hole 101, providing users with a clear and direct operating component. Different testing units can be switched with a simple linear sliding operation, simplifying the operation steps and avoiding the tedious process of repeatedly unpacking and locating sampling holes, making the testing process more intuitive and user-friendly. Each test strip storage slot 202... 2. A fixed arrangement of gastric pyloric test strips 203 is provided, and their position matches the test hole 102 on the outer casing 100. This ensures that when the slider 200 is slid to a specific position, the gastric pyloric test strip 203 is precisely aligned vertically with the test hole 102. This provides a standardized and consistent sample addition and observation window for each test, helping to reduce errors caused by operational position deviations or movement of the gastric pyloric test strip 203, thereby improving the reliability and consistency of the test results. Placing multiple gastric pyloric test strips 203 separately in the test card avoids the need for manual installation or removal by the user before testing, effectively reducing the possibility of contamination or damage during operation. This ensures the purity of the test sample and the hygiene and safety of the testing process from a physical structure perspective. Through the integrated structural design of the outer shell 100, slide key 200, and multi-test strip storage tank 202, the multiple testing function is highly integrated into a single device. This effectively solves the problems of single testing, scattered components, cumbersome operation steps, and potential errors caused by existing home-use gastric pylorus testing cards. It improves the ease of operation, ensures the standardization of testing, enhances the consistency of results, and improves the overall user experience, providing convenience and a better user experience for multiple, convenient, and reliable Helicobacter pylori screening in the home environment.

[0025] like Figure 2As shown, in this embodiment, the test strip storage tank 202 is provided with a test strip slot locking position 2021 for securing the gastric pylorus test strip 203; and / or a flexible stop 2022 is provided between two adjacent test strip storage tanks 202; and / or a flexible stop 2022 is provided on the side of the test hole 102 facing the test strip storage tank 202. By providing the test strip slot locking position 2021 on the test strip storage tank 202, a proprietary positioning and locking structure is provided for the gastric pylorus test strip 203, effectively preventing the test strip from shifting, loosening or falling off during transportation, sliding operation or equipment vibration, ensuring that the test strip is always in the preset correct position, thereby providing higher mechanical stability and reliability for the detection process. The flexible baffle 2022, positioned between two adjacent test strip reservoirs 202, forms a physical isolation barrier. This effectively prevents test strips in different reservoirs from contacting each other, avoiding physical damage or cross-contamination of the detection area (such as the coated antigen) caused by friction or collision between the pyloric test strips 203. This ensures the independence of each test unit and the accuracy of the test results. The flexible baffle 2022 is positioned on the side of the test hole 102 facing the test strip reservoir 202. When the slide key 200 moves and aligns a test strip reservoir 202 with the test hole 102, the flexible baffle 2022 can form a tight contact with the surrounding structure. This effectively reduces the risk of external contaminants entering the housing 100 through gaps at the test hole 102, and also helps prevent test samples from leaking into other test strip reservoirs 202, further improving the sealing and hygienic safety of the test card. The flexible stop 2022 features a flexible design that allows it to elastically deform upon contact and compression. This ensures good sealing and isolation while avoiding problems such as wear, abnormal noise, or excessive operating resistance that may occur with rigid contact. It helps maintain a smooth sliding operation and extends the service life of the components.

[0026] like Figure 2 and Figure 3As shown, in this embodiment, a stop structure is provided between the slide key 200 and the outer shell 100. The stop structure includes a stop lever 301 and a stop groove 302. The number and spacing of the stop grooves 302 are matched with the test strip storage tank 202. By sliding the slide key 200 in the inner cavity of the outer shell 100, the stop lever 301 is moved into one of the stop grooves 302, thereby making the test strip storage tank 202 corresponding to the stop groove 302 vertically aligned with the test hole 102. Alternatively, the number and spacing of the stop levers 301 are matched with the test strip storage tank 202. By sliding the slide key 200 in the inner cavity of the outer shell 100, the stop groove 302 is locked outside one of the stop levers 301, thereby making the test strip storage tank 202 corresponding to the stop lever 301 vertically aligned with the test hole 102. The gear mechanism allows users to perceive the positioning status of the gear lever 301 sliding into the gear slot 302 through clear tactile or audible feedback (such as a "click") when pushing the slide key 200. This positive physical feedback mechanism clearly indicates that the slide key 200 has accurately moved to the predetermined working position, effectively avoiding the misalignment problem between the test hole 102 and the test strip reservoir 202 caused by inaccurate positioning of the slide key 200, thus ensuring that each test is performed in the correct position. When the gear lever 301 and the gear slot 302 are engaged, a certain locking or holding force is generated, stabilizing the slide key 200 in the current position. It is not easy for it to shift due to accidental touch or equipment shaking, ensuring that the selected test strip reservoir 202 can maintain a persistent and accurate vertical alignment with the test hole 102. This provides a stable and reliable operating window for sample addition and observation, fundamentally eliminating operating position deviations, which is beneficial to the consistency and reliability of test results. The gear shift mechanism discretizes the continuous sliding stroke into several clearly defined positioning points, each corresponding to a test strip reservoir 202. This guides the user through a step-by-step operation, eliminating the need for the user to observe or judge alignment. This greatly simplifies the operation logic, making the entire testing process more intuitive, simple, and less prone to errors. It is particularly suitable for non-professional home users, enhancing the product's ease of use and user experience. The introduction of the mating structure between the gear shift lever 301 and the gear shift slot 302 increases the precision and interactivity of the product's internal structure. Its mechanical strength and durability are superior to positioning methods that rely solely on friction, contributing to improved overall product quality and lifespan.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, at least one end of the outer shell 100 has a pull-out opening 103. The drawer 400 is slidably assembled into the outer shell 100 via the pull-out opening 103. At least one sampling swab 500 is placed in the drawer slot 401 of the drawer 400. After the drawer 400 slides into the inner cavity of the outer shell 100, the pull-out opening 103 is closed by the end plate 402 of the drawer 400. The sampling swab 500, which originally needed to be packaged separately, is directly built into and stored in the drawer slot 401 of the drawer 400, making it part of the overall structure of the test card. This changes the state of the test card and the sampling swab 500 being separate and scattered in the prior art. Users no longer need to find or unpack the sampling swab 500 separately, realizing out-of-the-box use and greatly improving the integration, portability and ease of use of the product. After drawer 400 slides into the inner cavity of outer shell 100, its end plate 402 closes the pull-out opening 103, completely encapsulating the built-in sampling swab 500 inside the shell. This provides a sealed, dustproof, and contamination-proof storage environment for the sampling swab 500, effectively preventing contamination or damage before transportation, storage, and use. It physically ensures the sterility and hygiene of the sampling swab 500, guaranteeing the accuracy of test results. The drawer-style push-pull operation conforms to everyday habits, allowing users to easily retrieve and place the sampling swab 500 without an instruction manual. The process of using the sampling swab 500 is simplified to a simple "pull open - retrieve - push back" action. The operation steps are clear, intuitive, and smooth, significantly reducing the learning cost and usage threshold for users, and enhancing the overall user-friendliness of the operating experience. Once the drawer 400 is slid into place, the end plate 402 restores the appearance of the outer casing 100 to a closed and flat whole, avoiding the messiness caused by external accessories or scattered packaging. This not only makes the product structure compact, easy to carry and store, but also enhances the product's aesthetics and texture.

[0028] like Figure 2 and Figure 3 As shown, in this embodiment, sliding guide rails 403 are respectively arranged on both sides of the bottom of the drawer 400. The sliding guide rails 403 concentrate the force and friction stress during the pulling process onto the dedicated rails, reducing the friction between the drawer 400 and the surface of the lower cover 109 during pulling out and pushing in, making the movement of the drawer 400 smoother, avoiding direct friction and wear between the drawer 400 and other non-load-bearing parts of the outer shell 100, which not only protects the main structure and extends the service life of the product, but also makes the drawer 400 more stable after closing, less prone to loosening, and improves the overall structural strength and quality of the product; it ensures that the drawer 400 can slide precisely along the predetermined path to close, so that the end plate 402 can accurately and tightly seal the pull-out opening 103, which helps to maintain the integrity and airtightness of the outer shell 100, better achieve the protection function of dust prevention and pollution prevention, and ensure the hygiene and safety of the built-in sampling swab 500.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the bottom of the drawer 400 is also provided with a push-out opening 404, through which the sampling swab 500 is pushed to facilitate the removal of the sampling swab 500 from the drawer 400; and / or the bottom of the drawer 400 is also provided with a finger holder 405, which protrudes outside the outer shell 100 when the drawer 400 is fully slid into the inner cavity of the outer shell 100, and by applying force to the finger holder 405, the drawer 400, which is fully slid into the inner cavity of the outer shell 100, is slid out; and / Or the bottom of drawer 400 is also provided with a buckle 406, which cooperates with the limiting member 104 on the inner wall of the outer shell 100 to ensure that the drawer 400 pushed into the inner cavity of the outer shell 100 slides into place and ensures the relative positioning between the drawer 400 and the outer shell 100; and / or the rear end of drawer 400 is also provided with a rear baffle 407, which is used to limit the drawer 400 when it is pulled out and cooperate with the limiting member 104 on the inner wall of the outer shell 100 to prevent the drawer 400 from falling out. The push opening 404 is provided at the bottom of drawer 400, through which the user can push the sampling swab 500 from the bottom upwards to expose it for easy access, avoiding the inconvenience of picking the swab out of the narrow drawer slot 401 by hand, and reducing the risk of hand contact contamination of the swab sampling end, further ensuring the hygiene of the sampling swab 500. The finger catch 405 remains protruding from the outer casing 100 even after the drawer 400 is fully pushed in, forming a groove or protrusion specifically for applying force. This allows users to smoothly slide the drawer 400 out by naturally hooking the finger catch 405 without needing to pry with their fingernails or find a point of force, greatly simplifying the retrieval process and improving the user-friendliness and convenience of operation. Through the cooperation of the latch 406 and the upper limit member 104 on the inner wall of the outer casing 100, a clear locking sensation (such as a "click") or change in resistance is generated when the drawer 400 is pushed in, providing positive feedback to the user that the drawer is closed properly. At the same time, a certain locking force is generated to effectively prevent the drawer 400 from sliding out on its own due to gravity, vibration, or accidental contact, ensuring the structural integrity and airtightness of the product when carried or stored. The tail baffle 407 and the limiting member 104 inside the outer shell 100 form a physical anti-detachment mechanism; when the drawer 400 is pulled out to its maximum stroke, the tail baffle 407 will abut against the limiting member 104 to prevent the drawer 400 from moving further, thereby preventing it from completely detaching from the outer shell 100. This prevents accidents such as the drawer 400 falling or the sampling swab 500 scattering due to excessive force, thus improving the reliability and safety of the product.

[0030] like Figure 3As shown, in this embodiment, the inner wall surface of the outer casing 100 is also provided with multiple anti-tilting limiting structures 105. The multiple anti-tilting limiting structures 105 are arranged at intervals along the movement direction of the drawer 400 to prevent the drawer 400 from tilting up and down when it slides out. The anti-tilting limiting structures 105 have multi-point sliding contact with the upper surface of the drawer 400. Combined with the cooperation relationship formed by the side wall of the drawer 400 and the first guide rib 106 and / or the second guide rib 107 in the lower cover 109, and the sliding contact between the sliding guide rail 403 at the bottom of the drawer 400 and the lower cover 109, the drawer 400 is provided with movement constraints and support. When the drawer 400 is subjected to unbalanced forces or its own gravity torque and tends to warp, the anti-tilting limiting structures 105 can effectively resist and limit the displacement and deflection of the drawer 400 in the vertical direction, ensuring that the drawer 400 always maintains a smooth linear movement throughout the entire pull-out stroke, avoiding problems such as jamming, abnormal noise, or accelerated wear. The anti-tilting limiting structure 105 is arranged at multiple intervals and in a strip-like configuration. Through the interval arrangement of multiple limiting points along the direction of movement and / or the limiting strips along the direction of movement, it provides continuous and uniform guidance and support for the drawer 400, significantly improving the rigidity and integrity of the drawer 400 during movement. This reduces the looseness caused by structural deformation or wobbling, making the pull-out operation feel more stable, smooth, and sophisticated, further optimizing the user experience. The anti-tilting limiting structure 105 shares the bending moment and lateral force borne by the sliding rail 403 of the drawer 400, reducing the risk of deformation, wear, or damage to the drawer 400 and its sliding rail 403 due to long-term improper stress. By preventing swaying, it fundamentally reduces abnormal contact and friction, helping to maintain good operational performance even after long-term use and extending the product's lifespan. Optionally, the multiple anti-warping limiting structures 105 are arranged in a triangular pattern, and each anti-warping limiting structure 105 is arranged along the width direction of the outer shell 100, such as... Figure 3 As shown. Optionally, the anti-tilting limiting structure 105 and the limiting member 104 are integrally arranged, with the two anti-tilting limiting structures 105 respectively arranged at the ends of the limiting member 104, and combined to form an Ω-shaped structure.

[0031] like Figure 2As shown, in this embodiment, first guide ribs 106 are respectively arranged on both sides of the inner wall of the outer shell 100. The first guide ribs 106 are used to cooperate with the side of the slide key 200 to realize the directional sliding of the slide key 200; and / or second guide ribs 107 are respectively arranged on both sides of the inner wall of the outer shell 100. The second guide ribs 107 are used to cooperate with the side of the drawer 400 to realize the directional sliding of the drawer 400. The first guide ribs 106 and the slide key 200 or the second guide ribs 107 and the side of the drawer 400 form a close-fitting cooperation, providing a tight sliding constraint in the width direction of the components. This can effectively limit the lateral displacement or rotation of the slide key 200 and the drawer 400 during the sliding process, ensuring that they move strictly along the preset straight trajectory. This provides a key guiding guarantee for the precise alignment of the test paper storage slot 202 and the test hole 102, as well as the smooth opening and closing of the drawer 400. The first guide rib 106 or the second guide rib 107 concentrates the sliding contact surface on the guide rib, avoiding large-area contact and friction between the entire side wall of the slide key 200 / drawer 400 and the inner wall of the outer casing 100. This not only significantly reduces sliding resistance, making operation smoother and easier, but also reduces the wear area and wear particles, helping to maintain operational performance over long-term use and extending the product's service life. The symmetrically arranged first guide ribs 106 or second guide ribs 107 work together to form a stable double-rail sliding pair, enhancing the torsional and bending resistance of the slide key 200 and drawer 400 during movement, preventing them from skewing or jamming due to uneven force, and improving the reliability and stability of the entire mechanism under complex operating conditions. The first guide rib 106 or second guide rib 107 physically defines a unique installation and movement path for the slide key 200 and drawer 400, avoiding the possibility of reverse or incorrect installation of components, and improving the success rate and efficiency of production assembly. Optionally, the sliding contact surfaces of the first guide rib 106 and / or the second guide rib 107 are designed as arc-shaped surfaces to ensure smooth sliding of the slide key 200 and the drawer 400. Optionally, the slide key 200 and the drawer 400 are arranged in layers from top to bottom. Optionally, the second guide rib 107 is also provided with a clearance groove 112. The clearance groove 112 is used to ensure that the anti-tilting limiting structure 105 falls into the clearance groove 112 when the upper cover 108 is assembled to the lower cover 109, thereby fixing both ends of the anti-tilting limiting structure 105 in a fixed position. When the anti-tilting limiting structure 105 and the limiting member 104 are integrally arranged, the first end of the anti-tilting limiting structure 105 and the limiting member 104 are integrally formed, and the limiting member 104 and the anti-tilting limiting structure 105 are mutually supported and constrained by the vertical connecting plate. The second end of the anti-tilting limiting structure 105 is fixed in the clearance groove 112. When the anti-tilting limiting structure 105 is a straight plate that runs through the entire length, both ends of the anti-tilting limiting structure 105 fall into the clearance groove 112 on the corresponding side.By avoiding the end of the anti-tilting limiting structure 105 through the clearance groove 112, and achieving the positioning and installation of the end of the anti-tilting limiting structure 105, the stability and smoothness of the drawer 400 during the pulling out or pushing in process are ensured, and vibration, motion interference, and motion interference between them are reduced.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the outer shell 100 includes an upper cover 108 and a lower cover 109. The lower cover 109 is groove-shaped, and the upper cover 108 is plate-shaped. The upper cover 108 is fitted into the snap-fit ​​groove of the lower cover 109 and is positioned by insertion through positioning posts 110. Multiple sets of positioning posts 110 are arranged, and the multiple sets of positioning posts 110 are arranged at intervals along the edge of the lower cover 109. By fitting the plate-shaped upper cover 108 into the snap-fit ​​groove of the groove-shaped lower cover 109, and using multiple sets of positioning posts 110 arranged at intervals along the edge for insertion and positioning (the positioning posts 110 of the upper cover 108 are inserted into the positioning posts 110 of the lower cover 109; or the positioning posts 110 of the lower cover 109 are inserted into the positioning posts 110 of the upper cover 108), multiple precise and discrete positioning references are provided for the assembly of the upper cover 108 and the lower cover 109. This effectively limits the misalignment and rotation of the upper cover 108 and the lower cover 109 in the plane, ensuring that the two always maintain the relative position required by the design, thereby ensuring the dimensional accuracy and form and position consistency of the overall structure of the outer shell 100. After insertion, multiple sets of positioning posts 110 form internal support points distributed at various locations along the edge of the housing. This tightly connects the upper cover 108 and the lower cover 109 into a single unit, significantly enhancing the housing's resistance to bending and torsional deformation. It prevents deformation caused by external pressure or internal component forces, thus providing a stable and reliable working environment for the precision internal sliding keys 200 and drawers 400. The matching of the corresponding insertion holes of the positioning posts 110 between the upper cover 108 and the lower cover 109 provides clear guidance and error prevention, simplifying the production assembly process, reducing reliance on assembly skills, facilitating rapid and accurate batch assembly, and improving production efficiency and first-pass yield. Precise alignment and reliable connection ensure the tightness and consistency of the joint between the upper cover 108 and the lower cover 109, helping to prevent the intrusion of external contaminants. It also better isolates internal components (such as the pyloric test strip 203 and the sampling swab 500) from the external environment, enhancing the product's protective performance to a certain extent.

[0033] like Figure 1As shown, in this embodiment, the surface of the upper cover 108 and / or the surface of the lower cover 109 are provided with an identification area 111, which is used to indicate the area function and usage method. The labeling area 111 uses visual elements such as text, symbols, or graphics to directly and clearly indicate the function of specific areas (such as test hole 102, control hole 101, pull-out port 103, etc.) or the correct operating steps to the user. Integrating the user manual into the product itself eliminates the need for frequent consultation of separate paper manuals, greatly reducing the risk of misoperation due to misunderstanding or forgetting the operating procedures, and improving the accuracy and reliability of use. Printing the instructions directly next to the relevant functional areas provides intuitive guidance, greatly simplifying the human-computer interaction process and making the operation more intuitive and natural. This significantly reduces the learning cost and psychological burden for non-professional users, making the product more user-friendly and easy to use, thereby improving the overall user experience. Clear functional labeling makes all interfaces and operating components of the product readily apparent, giving the product a more professional and reliable appearance. It also helps establish a correct understanding and trust in the product among users, reflecting the designer's in-depth consideration of user needs and usage details.

[0034] In implementation, a gastric pylorus detection card is provided, with one card containing two gastric pylorus test strips 203, allowing for two tests. A slider 200 containing the two gastric pylorus test strips 203 is nestled between an upper cover 108 and a lower cover 109. The upper cover 108 has only one test hole 102. Sliding the slider 200 allows switching between A and B modes, ensuring that one of the gastric pylorus test strips 203 is aligned with the test hole 102 and reliably positioned, preventing displacement due to shaking or flipping, thus reducing the chance of untested gastric pylorus test strips 203 being completely removed. The extended exposure time to air adds to the enjoyment of use. Meanwhile, a drawer 400 for holding two sampling swabs 500 is located between the slide key 200 and the lower cover 109. When the drawer 400 is pulled out to its maximum position, it is stopped by a stop on the upper cover 108, preventing it from detaching from the test card. Furthermore, when the drawer 400 is closed, it is self-locking through a latch 406 on the bottom of the drawer and a limiting member 104 on the lower cover 109. Additionally, the front of the upper cover 108 displays usage instructions. Removing the test card from the packaging provides access to all necessary accessories and allows direct reading of the instructions for testing. This avoids carelessly discarding small accessories along with the packaging and improves efficiency by allowing users to directly read the usage instructions from the test card, significantly enhancing the user experience.

[0035] like Figures 1-3As shown, the top cover 108 has a test hole 102, with a gastric pylorus test strip 203 mounted on the test strip storage tank 202 directly below it; it also has a control hole 101 for inserting the push rod 201 on the slide key 200 and leaving sufficient space for it; it also has a limiting member 104 shared by the slide key 200 and the drawer 400 to limit the sliding amount of the slide key 200 and control the maximum extension amount of the drawer 400; and it has an anti-tilting limiting structure 105 to prevent the drawer 400 from tilting. The vertical tilt when the maximum amount is drawn improves the user experience. In addition, six positioning posts 110 are provided for interference-fitting connection with the six positioning posts 110 of the lower cover 109, which encloses the slide key 200, test paper, drawer 400, and sampling swab 500 between the upper cover 108 and the lower cover 109. At the same time, the front of the upper cover 108 is also printed with operation steps and color-coded comparison test results, allowing users to directly follow the prompts to perform sampling tests and compare results, greatly improving the convenience of use.

[0036] The slide key 200 is equipped with a push rod 201, which allows switching to ensure that one of the gastric pylorus test strips 203 is aligned with the test hole 102 of the upper cover 108 by pushing the push rod 201; it also has two test strip storage slots 202, each with three test strip slot holders 2021, each slot can hold one gastric pylorus test strip 203, which is fixed in place by the test strip slot holders 2021; it also has a position lever 301, which adjusts the position when the push rod 201 is pushed. When one of the test strips is aligned with the test hole 102 of the upper cover 108, the shift lever 301 is engaged in a corresponding shift slot 302 of the lower cover 109. When the test card is shaken, the slide key 200 will not shift, and the selected gastric pylorus test strip 203 will always be aligned with the test hole 102 of the upper cover 108. At the same time, when the slide key 200 is pushed, the user's hand can feel the shift position when it is pushed, and the user can also receive tactile feedback to complete the switching of the gastric pylorus test strip 203, which improves the user experience. The pylorus test strip 203 is yellow and is placed in the two test strip slots of the slide key 200. When dental plaque is sampled and applied to its surface with the sampling swab 500, a reaction will occur. When the result is negative, it remains yellow, and when the result is positive, it turns purple. The user obtains the test result by comparing the color markings of the test result on the top cover 108. Drawer 400 is installed between slide key 200 and lower cover 109. Its internal drawer slot 401 holds two sampling swabs 500 wrapped in coated paper. The bottom surface has a push-out opening 404. When the drawer 400 is pulled outwards from the test card to its outermost position with either the left or right hand, the ring finger can be used to push the sampling swab 500 up a certain height through the push-out opening 404, and then the thumb and forefinger can be used to pinch the sampling swab 500 and pull it out of the drawer 400. The bottom surface has two sliding guide rails 403 to reduce friction with the surface of the lower cover 109 during pulling out and pushing in, making the movement of the drawer 400 smoother. The outer side of the bottom surface has finger holders 405. At 0, use one finger to hold the finger holder 405 and pull the drawer 400 outward. When the drawer 400 is pulled to the maximum outward position, the tail baffle 407 on the drawer 400 will be blocked by the sliding key 200 on the top cover 108 and the common limiting member 104 of the drawer 400, so that the drawer 400 can be pulled out of the detection card but will not detach from the detection card. At the same time, at the front end of the bottom surface of the drawer 400, next to the finger holder 405, there is also a buckle 406. When the drawer 400 is closed, the buckle 406 is locked in the limiting member 104 of the bottom cover 109, ensuring that the drawer 400 will not detach from the detection card when no external force is used to pull the drawer 400. The lower cover 109 has six positioning posts 110 inside, which are used to fix together with the six positioning posts 110 of the upper cover 108 through an interference fit, enclosing other parts between the upper cover 108 and the lower cover 109. Inside the lower cover 109, there are also four first guide ribs 106 (two on each side) and two second guide ribs 107 (one on each side). The sliding key 200 is placed between the two guide ribs and above the second guide ribs 107. When the push rod 201 on the sliding key 200 is pushed, the bottom surface of the sliding key 200 slides against the top surface of the second guide rib 107, and the two guide ribs... The slide key 200 is guided on both sides; the sides of the first guide rib 106 and the top sides of the second guide rib 107 are rounded to minimize the frictional resistance of the slide key 200 during sliding; at the same time, the second guide rib 107 of the lower cover 109 also plays a guiding and limiting role on both sides during the pulling out and pushing in of the drawer 400; in addition, a limiting member 104 is provided at the position corresponding to the buckle 406 of the drawer 400. When the drawer 400 is closed, the limiting member 104 blocks the buckle 406 of the drawer 400 to prevent the drawer 400 from popping out under the action of external forces such as shaking and vibration.

[0037] The sampling swab 500 is packaged in coated paper and placed in the drawer slot 401 of the test card drawer 400. To take out the packaged sampling swab 500 from the test card drawer 400, simply tear off the outer coated paper.

[0038] Throughout the process, after removing the test card from the packaging, slide key 200 is positioned in the preset A setting, with the gastric pylorus test strip 203, which matches setting A, aligned with the test hole 102 on the top cover 108. Pull out drawer 400 and remove a sampling swab 500 packaged in coated paper. Tear open the coated paper and remove the sampling swab 500. Following the test steps indicated on the test card, collect tartar from between 2-3 teeth and apply it to the gastric pylorus test strip 203. After letting it stand at room temperature for 3 minutes, observe the color change. If the gastric pylorus test strip 203 turns purplish-red, the test result is positive; if it does not change color, the result is negative. At this point, slide key 200 can be switched to setting B, and the above steps can be repeated for a second test.
