[0003] In the current technical field of biological detection equipment, existing reagent strip detection devices have many disadvantages and inconveniences. Common problems include: (1) The operation process is complex, and the sample addition and result reading steps are not convenient and efficient enough, increasing the detection time and operation difficulty; (2) The sample addition position lacks effective protection measures and is easily contaminated by the outside world, affecting the accuracy and reliability of the detection results; (3) The stability of the equipment is poor, and it is prone to shaking or displacement during use, resulting in deviations in the detection results and increasing the possibility of misjudgment; (4) Some detection devices cannot flexibly adapt to different detection environments and requirements, have poor versatility, and are difficult to handle diverse detection scenarios and sample types; (5) At the same time, some detection devices are not convenient to pick up. They lack effective anti-slip designs, making it easy for operators to drop them when picking them up. This may not only cause damage to the equipment but also pose a risk of sample leakage and affect the detection results. Moreover, some detection devices are large in size and irregular in shape, lacking reasonable handheld parts or portable structures, increasing the difficulty of carrying and transferring. Especially in scenarios where the detection location needs to be frequently changed, it greatly reduces the work efficiency. In addition, the center of gravity of some devices is not reasonably designed, making it difficult to maintain balance when picking them up, easily causing the device to tilt or even fall over, further increasing the complexity and instability of the operation and affecting the normal progress of the detection work.

[0004] Therefore, there is an urgent need to find a brand-new reagent strip detection device with the advantages of simple and efficient operation, strict protection of the sample addition position, strong stability, high versatility, clear and intuitive result reading, convenient picking up and carrying, etc., which can effectively meet various needs in actual detection work and improve the detection efficiency and quality.

The edge of the result observation window 6 is rounded to prevent scratching the operator; on the left and right sides of the housing 1, there are respectively a clamping structure (1) 7 and a clamping structure (2) 8. On the detection module 2 and the base 3, there are respectively a clamping groove (1) 9 and a clamping groove (2) 10 that match the movement track of the housing 1.

When the operator applies a pushing or pulling force to the housing 1, the clamping structure (1) 7 and the clamping structure (2) 8 on the housing 1 move freely in the clamping groove (1) 9 of the detection module 2 and the clamping groove (2) 10 of the base 3. The clamping groove (1) 9 of the detection module 2 and the clamping groove (2) 10 of the base 3 are arranged oppositely.

[0047] At the front end of the upper surface of the detection module 2, there is a sample addition groove 11. The edge of the sample addition groove 11 is provided with an arc-shaped concave structure 12 for preventing the sample from splashing out; on the upper surface of the detection module 2, there is a detection result display window 13 for efficiently reading the detection results. When the sample addition is completed, the detection result display window 13 and the result observation window 6 are in the same position. The sample addition groove 11 and the detection result display window 13 are provided with a protection structure to prevent contamination and scratching. The protection structure is the housing 1. The housing 1 can move relative to the detection module 2 to switch the exposure states of the sample addition groove 11 and the detection result display window 13; when adding the sample, one end of the housing 1 first covers the detection result display window 13 on the detection module 2 to completely expose the sample addition groove 11, and at this time, the sample addition operation can be carried out; after the sample addition is completed, continue to push or pull the housing 1 to move it to the other end. At this time, the housing 1 covers the sample addition groove 11, and the detection result display window 13 is completely exposed, so that the operator can read the detection results, and at the same time, effectively cover the sample addition groove 11 to prevent contamination.

At the same time, this connection manner also facilitates the installation and disassembly of the detection module 2, which is beneficial to the maintenance of the reagent strip detection device and the replacement of components. At the same time, in cooperation with the detachable clamping connection between the housing 1, the detection module 2 and the base 3, through the multiple connection manners, the housing 1, the detection module 2 and the base 3 are combined into a stable and detachable integrated structure, ensuring the integrity and reliability of the reagent strip detection device during use.

[0049] The base 3 is provided with a reagent strip placement position 18 for placing the reagent strip 19. The reagent strip 19 is provided with a sample addition area, a reaction area, a color development area, and a water absorption area. The sample addition area is used to receive and hold the sample to be detected; the reaction area is the key area where the sample reacts chemically with the reagent; the color development area displays the test result through color change or other observable signals; the water absorption area is used to absorb excess sample and reagent to promote the flow of the sample on the reagent strip 19. Along the sample flow direction, the reagent strip 19 is successively provided with a sample pad 24, a conjugate pad 25, a reaction membrane 26, a water absorption pad 27, and a bottom plate 28.

The sample pad 24 is aligned with the sample addition groove 11, and the area where the test line 29 and the control line 30 are arranged is consistent with the position of the test result display window 13. On the other side of the base 3, there is a filter paper placement position 31 for placing the filter paper 32 to further absorb excess sample and avoid interfering with the test result. The lower surface of the base 3 is provided with an anti-slip layer 33, which is composed of a plurality of small grooves and is used to increase the friction force to make the reagent strip detection device more stable (although the small groove structure on the anti-slip layer 33 is not specifically shown in the Figure 3 figure, it can be understood that different-shaped small groove structures can be correspondingly set on the lower surface of the base 3 according to user needs to increase the friction force of the base 3); on one side of the edge of the lower surface of the base 3, there is also an inwardly concave block structure, which is a stable auxiliary card slot 34 to further improve the stability of the entire reagent strip detection device and facilitate the taking of the reagent strip detection device.

[0050] II. Working Principle of the Reagent Strip Detection Device

[0051] A brand-new reagent strip detection device designed by the utility model has the following specific working principle: First, accurately place the reagent strip 19 and the filter paper 32 on the reagent strip placement position 18 and the filter paper placement position 31 of the base 3, and through the clamping structure between the housing 1, the detection module 2 and the base 3, combine the above structures into a detachable integrated structure. The operator moves the housing 1 through the groove-like structure 5 at one end of the housing 1 or the indentation 4 on the surface of the housing 1. During the sample addition stage, move the housing 1 to expose the sample addition groove 11, and accurately drop the sample into the sample pad 24 of the reagent strip 19 through the sample addition groove 11; after the sample addition is completed, move the housing 1 again to shield the sample addition groove 11, and at the same time expose the detection result display window 13, and the reaction result is presented in the detection result display window 13. The operator clearly reads the detection result through the result observation window 6 on the housing 1.

[0052] During the detection process, the anti-slip layer 33 and the stable auxiliary card slot 34 of the base 3 ensure the stability of the entire device, preventing the shaking and relative displacement of the device from affecting the detection result. The filter paper 32 on the base 3 can further absorb the excess sample and maintain the stability of the detection environment. The convex structure 16 on the lower surface of the detection module 2 is tightly connected to the clamping hole 17 of the base 3, ensuring that the detection module 2 will not be displaced or shaken during operation, thereby guaranteeing the accuracy and stability of the detection result.

[0053] The reagent strip detection device of the utility model realizes a convenient, accurate and stable detection process through the coordinated action of various components.

[0054] III. Operation Process of the Reagent Strip Detection Device

[0055] The operation process of the utility model is as follows: The operator first accurately places the reagent strip 19 on the reagent strip placement position 18 of the base 3, and then moves the housing 1 to completely expose the sample addition groove 11 for sample addition; after the sample addition is completed, move the housing 1 again to shield the sample addition groove 11, and at this time the detection result display window 13 is completely exposed, and the detection result is read. During the detection process, the excess sample is absorbed by the filter paper 32.

[0094] Example 2 Structure Optimization of a Reagent Strip Detection Device

[0095] Traditional reagent strip detection devices have many defects. First, the surface of the housing is too smooth, resulting in easy slipping during operation and affecting the detection efficiency; the structure of the sample addition slot is unreasonable, with too large an opening, which easily causes sample splashing, not only wasting samples but also potentially polluting the detection environment; at the same time, the protection of the sample addition position is insufficient, making it vulnerable to external pollution and affecting the accuracy of the detection results; the stability of the base is insufficient, and it is prone to shaking during operation, affecting the accuracy of the detection; and there are no effective anti-slip measures on the base, making it easy to slide when placed; in addition, it is inconvenient to pick up and carry, increasing the difficulty and risk of use; at the same time, the design of the placement position of the reagent strip is not precise enough, making it difficult to accurately fix the reagent strip and affecting the reliability of the detection results.

[0096] In response to the above defects, the utility model has carried out the following structural optimizations:

[0097] I. Optimization of the housing

[0098] 1. Dents are added to the surface of the housing, greatly enhancing the friction force, effectively preventing slipping during operation, and facilitating the operator to move the housing, thereby accurately controlling the exposed state of the sample addition slot and the detection result display window, and ensuring the smooth progress of the detection process;

[0099] 2. A groove-like structure is added to one end of the housing, which fits the finger operation better, facilitating the operator to push or pull the housing, thereby realizing the movement of the housing to switch the exposed state of the sample addition slot and the detection result display window, and improving the comfort and convenience of pushing or pulling;

[0100] 3. Clamping structures are arranged on both sides of the housing, which are detachably clamped with the clamping grooves on one side of the detection module and the clamping grooves on one side of the base, ensuring the firm connection between the housing and the detection module and the base, and also facilitating disassembly and maintenance;

[0101] 4. Protrusions are added to the lower surface of the housing, which cooperate with the long-strip grooves on the detection module, enabling the housing to move smoothly along the established track, accurately controlling the exposure and shielding of the sample addition slot and the detection result display window, and ensuring the accuracy and stability of the operation.

[0102] II. Optimization of the sample addition slot

[0103] 1. The sample loading slot is adjusted from the original oversized opening to a circular shape, and a circle of inwardly concave arc-shaped square structure is set on the edge of the sample loading slot, which significantly reduces the risk of sample splashing and ensures the accuracy and safety of the sample loading process;

[0104] 2. A protective structure, specifically a shell, is added above the sample loading slot. After the sample loading is completed, the sample loading slot is completely covered by the movement of the shell, further ensuring the safety and cleanliness of the sample loading process.

[0105] 3. Optimization of the base

[0106] 1. The reagent strip placement position has been precisely designed with a positioning slot to ensure that the reagent strip can be placed accurately and firmly;

[0107] 2. A filter paper placement position is added to place filter paper to further absorb excess samples during the test process to avoid interference with the test results, maintain the stability of the test environment, and ensure the accuracy of the test;

[0108] 3. A raised structure is added to the lower surface of the detection module, which cooperates with the clamping hole on the upper surface of the base, making the detection module more stable during work and less likely to move or shake, thereby ensuring the accuracy and stability of the detection results;

[0109] 4. The lower surface of the base is covered with an anti-slip layer composed of fine grooves, which greatly improves the stability during placement and effectively avoids sliding;

[0110] 5. A stable auxiliary card slot is added to further enhance the stability of the base and facilitate the removal and operation of the equipment.

[0111] By optimizing the structures of the shell, the sample adding slot, the detection module, the base, etc., the reagent strip detection device provided by the utility model is more convenient to operate, more stable, more accurate and more reliable, and can effectively meet the detection needs.
