Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a single-use chemiluminescent reagent strip. Background Technology

[0002] Chemiluminescence immunoassay technology, due to its high sensitivity and selectivity, has been widely used in clinical diagnostics, drug analysis, and environmental monitoring. With the development of point-of-care testing (POCT) technologies, magnetic particle chemiluminescence immunoassay analyzers have become important tools in the testing field. To meet the needs of community hospitals and small testing institutions, a POCT instrument based on a magnetic particle chemiluminescence system has been introduced to the market. This instrument typically uses single-use test strips, with one strip per sample. The test strip is pre-encapsulated with reaction reagents, magnetic beads, and cleaning solution to meet the sample's testing requirements.

[0003] In existing technologies, a TIP tip is used to aspirate the liquid within the test strip, completing the transfer of reagents and magnetic beads. However, existing equipment typically requires a dedicated tray for storing and placing the TIP tips, resulting in a bulky instrument and inconvenience. Furthermore, TIP tip management is prone to misplacement or omission, and the recycling of discarded TIP tips is also cumbersome. Failure to promptly recycle discarded TIP tips may lead to reuse, causing cross-contamination and affecting the accuracy of test results. Utility Model Content

[0004] The main purpose of this invention is to provide a single-use chemiluminescent reagent strip, which aims to simplify the device structure and facilitate the installation and recycling of the TIP head.

[0005] To achieve the above objectives, this utility model proposes a single-use chemiluminescent reagent strip, comprising a connecting plate, a photometer mounting hole on one side of the connecting plate, and a TIP head mounting hole on the other side. Multiple detection holes are arrayed on the connecting plate along the direction from the TIP head mounting hole to the photometer mounting hole. A sample receiving hole is provided opposite the TIP head mounting hole to the TIP head mounting hole. The TIP head mounting hole, sample receiving hole, multiple detection holes, and photometer mounting hole are arranged sequentially.

[0006] The TIP head mounting hole is provided with a TIP head structure, and the photometric mounting hole is connected to a test cup body. The test cup body includes a photometric mating hole and a mixed sample test hole, and the photometric mating hole surrounds the mixed sample test hole.

[0007] The bottom wall of the connecting plate is provided with reinforcing ribs along the direction from the TIP head mounting hole to the photometric mounting hole, and the reinforcing ribs pass through the central axis of the sample receiving hole and multiple detection holes.

[0008] In one embodiment of this application, the mixed sample test hole is provided with a reflective portion away from the photometer mounting hole, and the reflective portion is recessed with a conical structure towards the connecting plate;

[0009] The bottom wall of the connecting plate is provided with a reinforcing structure relative to the photometer mounting hole. The reinforcing structure wraps around the test cup body, and one end of the reinforcing rib is connected to the reinforcing structure.

[0010] In one embodiment of this application, the top of the connecting plate is provided with a plurality of encapsulation protrusions of the same height relative to the outer periphery of the plurality of detection holes, and adjacent plurality of encapsulation protrusions are connected to each other;

[0011] The top of the connecting plate is provided with heat-sealing protrusions opposite to the multiple detection holes. The heat-sealing protrusions are connected to the outer periphery of the connecting plate and surround the multiple detection holes.

[0012] In one embodiment of this application, a plurality of detection holes are provided with dilution holes facing the sample receiving hole, and the horizontal cross-section of the dilution holes is rectangular.

[0013] In one embodiment of this application, a plurality of detection holes are provided with substrate storage holes facing the test cup body, and enzyme storage holes, cleaning holes, and reagent storage holes are provided between the substrate storage holes and the dilution holes;

[0014] The cleaning hole and reagent storage hole are provided in multiple ways, and the multiple cleaning holes and reagent storage holes are arranged alternately. The reagent storage hole is connected to the substrate temporary storage hole.

[0015] In one embodiment of this application, the sample receiving hole, substrate storage hole, enzyme storage hole, cleaning hole, and reagent storage hole have an arc-shaped bottom at the end away from the connecting plate, and the diameter of the arc-shaped bottom is larger than the diameter of the TIP head structure facing the arc-shaped bottom.

[0016] In one embodiment of this application, the bottom wall of the connecting plate is provided with a first limiting plate and a second limiting plate, and the first limiting plate is connected to one end of the connecting plate;

[0017] The second limiting plate is located between the sample receiving hole and the dilution hole.

[0018] In one embodiment of this application, one end of the connecting plate is provided with a hand grip anti-slip part, which wraps around one end of the connecting plate and is connected to the TIP head mounting hole;

[0019] The other end of the connecting plate is provided with a message scanning unit, which is located at the upper end of the connecting plate and connected to one side of the test cup.

[0020] By adopting the above technical solution, this utility model has the following advantages:

[0021] 1. The connecting plate is made of transparent material for the reagent strip, and the test cup is a black cup made of light-blocking material (preferably black, but other light-blocking colors are also acceptable). During production, the test cup is interference-fitted into the photometer mounting hole on one side of the connecting plate. During use, there is no need for manual reinstallation of the black cup, simplifying the testing process and effectively improving testing efficiency. Simultaneously, the TIP head structure is connected to the TIP head mounting hole on the connecting plate away from the photometer mounting hole. With the TIP head structure and the black cup positioned on opposite sides of the connecting plate, POCT and other testing instruments can grasp the TIP head structure when testing the reagent strip, sequentially sampling through the sample receiving hole and rapidly testing as it passes through multiple detection holes, ensuring the reagent strip's testing accuracy and efficiency.

[0022] 2. The TIP head mounting holes, sample receiving holes, multiple detection holes, and photometric mounting holes face the same direction and are arranged sequentially along the extension direction of the connecting plate. This reduces unnecessary displacement and alignment time when the machine grasps the TIP head structure for liquid collection and testing, ensuring testing efficiency. It also facilitates the recycling of the TIP head structure, preventing it from causing contamination outside. Furthermore, the sequential arrangement along a straight line facilitates the setting of reinforcing ribs, ensuring greater stability of the connecting plate when it enters the machine and operates. This effectively reduces the structural complexity of the connecting plate and ensures its durability.

[0023] 3. The upper diameter of the TIP head structure is larger than the TIP head mounting hole, ensuring the stability of the TIP head structure installation. Additionally, a photoelectric beam switch is installed on one side of the TIP head structure. When no TIP head is installed in the connecting plate, the photoelectric beam switch will not receive a reflected signal or the received reflected signal will differ from the signal when the TIP head structure is properly placed. The system will automatically determine that no TIP head structure is placed and issue a warning signal to remind the operator to replace the TIP head structure, thus preventing misplacement and omission. A test cup is connected inside the photometric mounting hole. The test cup includes a photometric mating hole and a mixed sample test hole. The mixed sample test hole is a conical structure with a taper of less than 2°, allowing the internal light signal to be completely emitted and minimizing the distance between the luminescent material and the instrument's photometric system in quantitative liquid conditions. The photometric aperture is arranged in a ring shape, and the detection head of the photon counter is engaged with this ring aperture to minimize contact between the outside air and the light-emitting material inside the photometric aperture or to reduce light leakage, thus reducing detection errors. The wall thickness of the mixed sample detection aperture is 0.4 to 0.8 mm, which can achieve heating incubation while meeting the requirements of light-shielding detection, so that the reaction system inside the photometric aperture can be heated rapidly, which can effectively improve the detection efficiency.

[0032] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] Reference Figures 1 to 5To achieve the above objectives, this utility model proposes a single-use chemiluminescent reagent strip, including a connecting plate 1. One end of the connecting plate 1 is provided with a photometer mounting hole 5, and the other end is provided with a TIP head mounting hole 2. The connecting plate 1 has a plurality of detection holes 4 arranged in an array along the direction from the TIP head mounting hole 2 to the photometer mounting hole 5. The detection holes 4 are provided with sample receiving holes 3 opposite to the TIP head mounting hole 2. The TIP head mounting hole 2, the sample receiving hole 3, the plurality of detection holes 4, and the photometer mounting hole 5 are arranged in sequence.

[0035] TIP head mounting hole 2 is provided with TIP head structure 21, and photometric mounting hole 5 is connected with test cup body 51. Test cup body 51 includes photometric mating hole 52 and mixed sample test hole 53. Photometric mating hole 52 surrounds mixed sample test hole 53.

[0036] The bottom wall of the connecting plate 1 is provided with reinforcing ribs 11 along the direction from the TIP head mounting hole 2 to the photometric mounting hole 5. The reinforcing ribs 11 pass through the central axis of the sample receiving hole 3 and multiple detection holes 4.

[0037] The connecting plate 1 is a reagent strip made of transparent material, and the test cup 51 is a black cup made of light-shielding material (preferably black, but other light-shielding colors are also acceptable). During production, the test cup 51 is interference-fitted into the photometric mounting hole 5 on one side of the connecting plate 1. During use, there is no need to manually reinstall the black cup, simplifying the testing steps and effectively improving testing efficiency. At the same time, the TIP head structure 21 is connected to the TIP head mounting hole 2 on the connecting plate 1 away from the photometric mounting hole 5. The TIP head structure 21 and the black cup are located on both sides of the connecting plate 1, so that when testing the reagent strip, POCT and other testing instruments can grasp the TIP head structure 21 and sequentially sample through the sample receiving hole 3, and quickly perform testing when passing through multiple detection holes 4 in sequence, ensuring the testing accuracy and efficiency of the reagent strip.

[0038] The TIP head mounting hole 2, sample receiving hole 3, multiple detection holes 4, and photometric mounting hole 5 are all oriented in the same direction and are arranged sequentially along the extension direction of the connecting plate 1. This allows the machine to reduce unnecessary displacement and alignment time when gripping the TIP head structure 21 for liquid collection and testing, ensuring testing efficiency. It also facilitates the recovery of the TIP head structure 21, preventing it from causing contamination outside. Furthermore, the sequential arrangement along a straight line facilitates the setting of the reinforcing rib 11, ensuring that the connecting plate 1 is more stable when it enters the machine and operates. This effectively reduces the structural complexity of the connecting plate 1 and ensures its durability.

[0039] The upper diameter of the TIP head structure 21 is larger than that of the TIP head mounting hole 2, ensuring the stability of the TIP head structure 21 during installation. A photoelectric beam switch is also installed on one side of the TIP head structure 21. When no TIP head is installed in the connecting plate 1, the photoelectric beam switch will not receive a reflected signal or the received reflected signal will differ from the signal when the TIP head structure 21 is properly placed. The system will then automatically determine that the TIP head structure 21 is not in place and issue a warning signal to remind the operator to reposition the TIP head structure 21, thus preventing misplacement and omission. A test cup 51 is connected inside the photometric mounting hole 5. The test cup 51 includes a photometric mating hole 52 and a mixed sample test hole 53. The mixed sample detection hole 4 is a conical structure with a taper of less than 2°, allowing the internal light signal to be completely emitted and minimizing the distance between the luminescent material and the instrument's photometric system in quantitative liquid conditions. The photometric aperture 52 is arranged in a ring shape. The detection head of the photon counter is engaged with this ring aperture to minimize contact between the outside air and the light-emitting material in the photometric aperture or to reduce light leakage, thus reducing detection errors. The wall thickness of the mixed sample detection aperture 4 is 0.4-0.8 mm. Under the premise of meeting the requirements of light-shielding detection, it can realize heating incubation, so that the reaction system in the photometric aperture can be heated rapidly, which can effectively improve the detection efficiency.

[0040] See also Figure 5 The mixed sample test hole 53 is provided with a reflective part 54 away from the photometer mounting hole 5. The reflective part 54 is recessed with a conical structure facing the connecting plate 1. The bottom wall of the connecting plate 1 is provided with a reinforcing structure 12 relative to the photometer mounting hole 5. The reinforcing structure 12 is wrapped around the test cup body 51, and one end of the reinforcing rib 11 is connected to the reinforcing structure 12.

[0041] The reflector 54 is a conical structure with a taper of less than 2°, which helps to completely reflect the internal light signal, eliminating the need for the ring-shaped photometric mating hole 52. This facilitates the connection and sealing of the equipment, ensuring testing results. The reinforcing structure 12 consists of multiple reinforcing ribs 11 arranged in a grid pattern. This ensures the connection effect of the black cup and effectively protects the connecting plate 1, preventing damage during the use or installation of the black cup. The connecting plate 1 has good strength.

[0042] See also Figure 1 The top of the connecting plate 1 is provided with multiple encapsulation protrusions 13 of the same height relative to the outer periphery of the multiple detection holes 4, and the multiple adjacent encapsulation protrusions 13 are connected to each other.

[0043] The top of the connecting plate 1 is provided with a heat-sealing protrusion 14 opposite to the multiple detection holes 4. The heat-sealing protrusion 14 is connected to the outer periphery of the connecting plate 1 and surrounds the multiple detection holes 4.

[0044] The substrate storage well 45, dilution well 41, enzyme storage well 42, cleaning well 43, and reagent storage well 44 are provided with encapsulation protrusions 13 of the same height at the upper edge of the well. That is, the upper surface of the reagent strip body corresponding to each well is provided with an encapsulation protrusion 13 of the same ring structure as the well opening, which facilitates heat sealing. The upper surface of the reagent strip body is also provided with a ring of heat-sealing protrusions 14 with a height lower than the encapsulation protrusions 13. The heat-sealing protrusions 14 surround all the wells except for the sample receiving well 3, the TIP head mounting well 2, and the black cup, making the sealing film adhered to the reagent strip body more aesthetically pleasing. At the same time, this encapsulation structure can ensure that the material in each detection well 4 is sealed before testing, thereby improving the testing accuracy.

[0045] See also Figures 1 to 5 Multiple detection holes 4 are provided with dilution holes 41 facing the sample receiving hole 3. The horizontal cross-section of the dilution holes 41 is rectangular.

[0046] The dilution well 41 is located on one side of the sample receiving well 3 to store diluent, which can dilute the sample to different concentrations to meet the detection requirements. The cross-section of the dilution well 41 is square. When the area of ​​the opening is greater than or equal to that of other detection wells 4, since the bottom walls of other test wells are all provided with arc bottoms and the diameter of the well gradually decreases as it moves away from the connecting plate 1, the horizontal cross-section of the dilution well 41 is rectangular. Therefore, the volume of the dilution well 41 is larger than that of other detection wells 4, so it can store more diluent.

[0047] See also Figures 1 to 2 Multiple detection holes 4 facing the test cup body 51 are provided with substrate storage holes 45. Between the substrate storage holes 45 and the dilution holes 41, there are reaction enzyme storage holes 42, cleaning holes 43 and reagent storage holes 44.

[0048] Multiple cleaning holes 43 and reagent storage holes 44 are provided, and the multiple cleaning holes 43 and reagent storage holes 44 are arranged alternately. The reagent storage holes 44 are connected to the substrate temporary storage hole 45.

[0049] In this embodiment, the sample receiving hole 3 is located at the front end of the reagent strip to store the sample. Its shape is a cone, wider at the top and narrower at the bottom, to facilitate sample injection. The enzyme storage hole 42 stores the enzyme reagent component and is also a cone, wider at the top and narrower at the bottom. Three magnetic bead storage holes 44 store the magnetic bead reagent component and are also cones, wider at the top and narrower at the bottom. Four cleaning holes 43 store the cleaning solution. The substrate storage hole 45 stores the reactive luminescent substrate. After the reagent strip encapsulates the relevant reagents in the corresponding detection hole 4, the surface is heat-sealed with an aluminum film. The cleaning hole 43 and the substrate storage hole 45 have the same structure, both including an upper cylindrical segment and a lower conical segment connected together. To facilitate hole formation and processing, the openings of the enzyme storage hole 42, reagent storage hole 44, cleaning hole 43, and substrate storage hole 45 are annular openings formed by alternating straight segments of equal length and two arc segments of equal arc length and radius. The consistent opening contours facilitate uniform piercing of the sealing film by the piercing head on the detection instrument. The TIP head mounting hole 2, sample receiving hole 3, dilution hole 41, enzyme storage hole 42, reagent storage hole 44, cleaning hole 43, and substrate temporary storage hole 45 are connected together by reinforcing ribs 11 to improve the structural strength of the reagent strip body. The capacity of the detection holes 4 is determined by the detection items and the types of reagents packaged; this embodiment is not limited to their capacities.

[0050] See also Figures 1 to 5 The sample receiving well 3, substrate temporary storage well 45, enzyme storage well 42, cleaning well 43, and reagent storage well 44 have an arc-shaped bottom at the end away from the connecting plate 1. The diameter of the arc-shaped bottom is larger than the diameter of the TIP head structure 21 facing the arc-shaped bottom end.

[0051] The sample receiving well 3, enzyme storage well 42, reagent storage well 44, cleaning well 43, and substrate temporary storage well 45 have rounded bottoms. The diameter of the rounded bottoms is larger than the diameter of the TIP tip opening, so that the TIP tip can be completely fitted to the bottom of the detection well 4, thereby making the liquid extraction more complete and reducing the amount of reagent residue.

[0052] See also Figure 1 The bottom wall of the connecting plate 1 is provided with a first limiting plate 15 and a second limiting plate 16. The first limiting plate 15 is connected to one end of the connecting plate 1; the second limiting plate 16 is located between the sample receiving hole 3 and the dilution hole 41.

[0053] The two sides of the connecting plate 1 can be inserted into the mounting slots of the reaction chamber of the testing mechanism to position it in the vertical direction. In addition, the connecting plate 1 is also provided with a first limiting plate 15 and a second limiting plate 16. The first limiting plate 15 is limited by the reaction chamber, and the second limiting plate 16 is limited by the limiting ball of the testing mechanism, so that the reagent strip is limited in the reaction chamber along the installation direction of the reagent strip, and the reagent strip is prevented from shaking or shifting during the testing process.

[0054] See also Figures 1 to 5 One end of the connecting plate 1 is provided with a hand grip anti-slip part, which wraps around one end of the connecting plate 1 and is connected to the TIP head mounting hole 2;

[0055] The other end of the connecting plate 1 is provided with a message scanning unit, which is located at the upper end of the connecting plate 1 and connected to one side of the test cup 51.

[0056] The left end of the reagent strip body features a non-slip grip with textured edges for easy handling. The rightmost end of the reagent strip also has a QR code scanning area. Specifically, this area is where the QR code is affixed; before testing, the device scans the QR code to obtain information about the reagent strip, facilitating its reading by the testing equipment.
