Description

Technical Field

[0001] This utility model relates to the field of reagent kit technology, and in particular to a constant temperature in vitro diagnostic reagent kit. Background Technology

[0002] In vitro diagnostic kits are primarily used in medical testing and disease screening, especially for rapid detection of temperature-sensitive biological samples and reaction systems. Through a closed structure and constant temperature environment, these kits ensure stable execution of all reactions during the testing process, effectively improving accuracy and reliability. They are widely used in various medical fields such as infectious disease detection, gene testing, chronic disease screening, and maternal and child health monitoring, meeting the convenient testing needs of hospitals, communities, and homes.

[0003] In existing technologies, common in vitro diagnostic kits mainly consist of an upper shell, a lower shell, and an internal test strip or reaction zone. The upper and lower shells are typically connected by a physical plug-in or snap-fit ​​structure. Internally, reagents react chemically or immunologically with the sample to generate visual results. After testing, users can directly read the results. However, some kits, in order to facilitate operation and reduce production costs, have simple shell designs, with the test port area directly exposed, lacking dedicated protection and sealing devices, resulting in poor sealing after use.

[0004] However, after use, the testing port of existing in vitro diagnostic kits is usually exposed. Biological samples added by the user during the testing process remain at or around the testing port. If the kit is carelessly discarded or exposed to air, it can easily cause environmental pollution and even pose a risk of spreading pathogens carried in the sample, especially when detecting infectious diseases. Therefore, traditional kits have poor safety protection performance after use and cannot effectively avoid secondary pollution to the environment and personnel. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a constant-temperature in vitro diagnostic reagent kit, which aims to improve the problem that after the reagent kit is used, the sample dripped in by the user with the detection port exposed to the outside may pollute the environment or even cause infection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a constant temperature in vitro diagnostic reagent kit, comprising a lower shell and an upper shell, wherein the lower shell is fitted into the upper shell, an observation port is provided inside the upper shell, a detection port and a slope are provided inside the upper shell, a protective component is provided on the top of the upper shell, a placement groove is provided inside the lower shell, and a limiting plate is fixedly connected to the bottom of the upper shell;

[0007] The protective component includes a cover plate, the bottom of which is abutted against the top of the inclined surface. A buckle plate is fixedly connected to the bottom of the cover plate, and the buckle plate is slidably connected inside the upper housing. The cover plate is fitted inside the detection port through the buckle plate. A sealing component is provided between the cover plate and the buckle plate, and a connecting component is provided between the cover plate and the upper housing.

[0008] As a further description of the above technical solution:

[0009] The sealing assembly includes a sealing ring, which is internally fixed to the outer wall of the cover plate and fits against the inner wall of the detection port.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes a connecting strip, one side of which is fixedly connected to the outer wall of the cover plate, and the other side of which is fixedly connected to the top of the upper housing.

[0012] As a further description of the above technical solution:

[0013] The lower housing has a slot inside and a reinforcing groove inside.

[0014] As a further description of the above technical solution:

[0015] A support block is fixedly connected inside the upper shell, and a breakage groove is formed inside the support block.

[0016] As a further description of the above technical solution:

[0017] A locking block is fixedly connected to one side of the support block, and the locking block fits into the locking slot.

[0018] As a further description of the above technical solution:

[0019] A reinforcing strip is fixedly connected to one side of the card block, and the reinforcing strip fits into the reinforcing groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the cover plate is first fastened inside the detection port, so that the buckle plate at the bottom of the cover plate is fitted and fixed with the upper shell. Then, the cover plate and the buckle plate are sealed by a sealing ring attached to the inner wall of the upper shell, which achieves the effect of protecting the detection port. This solves the problem that after the reagent kit is used, the detection port is exposed and the sample dripped in by the user may contaminate the environment or even cause infection, thus improving the safety of the diagnostic reagent kit.

[0022] 2. In this utility model, when the lower shell and the upper shell are forcibly separated, the reinforcing strip and the locking block are firmly embedded in the lower shell, so that the force is applied to the fracture groove, which causes the upper shell and the support block to break and become irreparable. This achieves the effect of preventing secondary use and solves the problem that the upper and lower shells of the traditional reagent kit are connected by a pin friction connection, which makes it easy to open and replace the internal test strips, allowing criminals to recycle and reuse them. This improves the practicality of the broken reagent kit. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a constant-temperature in vitro diagnostic reagent kit, comprising a lower shell 1 and an upper shell 2, wherein the lower shell 1 and the upper shell 2 are fitted together. The lower shell 1 is used to accommodate the internal detection reaction components and form a sealed space. An observation port 3 is provided inside the upper shell 2, which allows the user to directly observe the test results, improving the intuitiveness and ease of operation of the test. A detection port 4 is provided inside the upper shell 2, which is used to add the sample to be tested, ensuring that the sample can accurately enter the detection area. An inclined surface 5 is provided inside the upper shell 2, which is used to guide the dripped sample to flow smoothly. To prevent sample residue from causing detection errors in the detection area, a protective component is provided on the top of the upper shell 2. This component is used to seal the detection port 4 after the detection is completed, preventing residual sample leakage or environmental pollution, thus improving safety and hygiene. A placement slot 10 is provided inside the lower shell 1. The placement slot 10 is used to install and fix the test strip or reaction reagent, keeping it in a stable position during the detection process to ensure the accuracy of the detection. A limiting plate 11 is fixedly connected to the bottom of the upper shell 2. The limiting plate 11 is used to enhance the stability of the fit between the upper shell 2 and the lower shell 1, preventing misalignment of the upper and lower shells 1 from affecting the detection effect.

[0031] The protective assembly includes a cover plate 7, which covers the detection port 4 after testing, effectively isolating it from the external environment and preventing sample evaporation or leakage. The bottom of the cover plate 7 fits snugly against the top of the inclined surface 5. This snug fit design ensures that the cover plate 7 fits tightly against the inclined surface 5 when covering, enhancing the sealing effect and preventing sample residue leakage. A buckle plate 8 is fixedly connected to the bottom of the cover plate 7. The buckle plate 8 plays an auxiliary positioning and fixing role, ensuring that the cover plate 7 is firmly installed in the detection port 4 and preventing the cover plate 7 from loosening or falling off. The buckle plate 8 is slidably connected inside the upper housing 2. The sliding connection structure facilitates the easy insertion or removal of the cover plate 7 during use, improving the flexibility and convenience of operation. The cover plate 7 is fitted into the detection port 4 through the buckle plate 8. The fitting design ensures that the cover plate 7 and the detection port 4 form a stable connection, avoiding the risk of leakage caused by the cover plate 7 falling off under external force. A sealing assembly is provided between the cover plate 7 and the buckle plate 8. The sealing assembly further enhances the sealing performance between the cover plate 7 and the detection port 4, preventing any liquid or gas leakage. The sealing assembly includes a sealing ring 9, which is internally and fixedly connected to the outer wall of the cover plate 7. This fixed connection ensures that the sealing ring 9 will not shift or fall off during use, maintaining long-term sealing performance. The sealing ring 9 fits snugly against the inner wall of the detection port 4, and this tight fit effectively prevents sample leakage, ensuring the safety and environmental friendliness of the detection process. A connecting assembly is provided between the cover plate 7 and the upper housing 2. This assembly ensures that the cover plate 7 remains connected to the upper housing 2 at all times, preventing protective failure due to loss or misoperation of the cover plate 7. The connecting assembly includes a connecting strip 6. One side of the connecting strip 6 is fixedly connected to the outer wall of the cover plate 7, ensuring controlled movement of the cover plate 7 during opening or closing. The other side of the connecting strip 6 is fixedly connected to the top of the upper housing 2. This fixed connection ensures the stability and firmness of the connecting strip 6, improving the reliability and practicality of the overall structure.

[0032] Reference Figure 2 and Figure 4 The lower shell 1 has a slot 12 inside, which engages with a locking block 16 inside the upper shell 2 for positioning and fixing. This effectively prevents misalignment or loosening between the upper shell 2 and the lower shell 1, ensuring the stability and sealing of the overall reagent kit structure. The lower shell 1 also has a reinforcing groove 13 inside, which works in conjunction with a reinforcing strip 17 to enhance the structural strength of the lower shell 1, preventing deformation or damage under external forces and improving the durability and reliability of the reagent kit. The upper shell 2 has a fixed support block 14 inside, which increases the strength of the upper shell 2 and provides support for the internal connection and locking structure, ensuring that the upper shell 2 can withstand external forces without deformation during use. The support block 14 has a fracture groove 15 inside, which is a pre-designed fracture area. When subjected to forced separation by external force, it will fracture preferentially, ensuring that the reagent kit cannot be reassembled once disassembled. This effectively prevents reuse and ensures the single-use safety of the reagent kit. A locking block 16 is fixedly connected to one side of the support block 14. The locking block 16 is used to tightly engage with the locking groove 12 inside the lower shell 1, forming a robust locking structure. This prevents the reagent kit from loosening or falling off during use or transportation, ensuring the stability and accuracy of the detection process. A reinforcing strip 17 is fixedly connected to one side of the locking block 16. The reinforcing strip 17 engages with the reinforcing groove 13, further enhancing the overall structural strength and connection stability of the reagent kit. This effectively prevents damage or cracking of the reagent kit due to external forces during use, improving product reliability and safety.

[0033] Working principle: When using this constant temperature in vitro diagnostic reagent kit, the test strip is first placed in the lower shell 1 through the placement groove 10. Then, the upper shell 2 is fastened to the lower shell 1. The limiting plate 11 at the bottom of the upper shell 2 further limits the test strip. At the same time, the locking block 16 in the upper shell 2 is engaged with the locking groove 12 on the lower shell 1. The reinforcing strip 17 on one side of the locking block 16 is engaged with the reinforcing groove 13 to improve the connection strength between the locking block 16 and the locking groove 12. When the lower shell 1 and the upper shell 2 are forcibly separated, the reinforcing strip 17 and the locking block 16 are firmly engaged in the lower shell 1, so that the force is applied to the breakage groove 15, which causes the upper shell 2 and the support block 14 to break and become irreparable, thus achieving the effect of preventing secondary use.

[0034] During testing, a sample is dripped into the test port 4, and the reaction of the test strip is then observed through the observation port 3. When it is necessary to protect the test port 4, the cover plate 7 is connected to the lower shell 1 through the connecting strip 6, and the cover plate 7 is fastened inside the test port 4, so that the buckle plate 8 at the bottom of the cover plate 7 is fitted and fixed to the upper shell 2. Then, the cover plate 7 and the buckle plate 8 are sealed to the inner wall of the upper shell 2 through the sealing ring 9, so as to prevent the sample from contaminating the environment through the test port 4, thus achieving the effect of protecting the test port 4.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
