Description

Technical Field

[0001] This utility model relates to the field of reagent kits that are easy to move, pick up, place, and compare, specifically a reagent kit that is easy to move, pick up, place, and compare. Background Technology

[0002] A reagent kit is a set of tools specifically designed for a particular detection or experiment, typically containing all the chemical reagents and materials needed to perform a test. Reagent kits have wide applications in the medical and biological fields, favored for their ease of use, rapid operation, high specificity, and objective result interpretation. They are widely used in clinical diagnostics, pathogen detection, molecular biology research, drug development, and high-throughput screening. Due to their wide range of applications, reagent kits are designed and manufactured to simplify experimental procedures, reduce human error, and improve accuracy and efficiency. When selecting a reagent kit, the appropriate type should be chosen based on the specific application requirements to ensure optimal experimental results.

[0003] Currently, there are reagent kits on the market designed for various usage scenarios. For example, a reagent kit disclosed in Chinese Utility Model Patent Application No. CN201922266769.9 includes a box body, a lid, and reagent tubes. The lid is connected to the box body via a hinge. A rubber pad is provided on the bottom surface of the box body, and a fixed partition is provided inside the box body, on which the reagent tubes are placed. This utility model has a reasonable structural design, is easy to use, and can effectively prevent the reagent tubes from shaking inside the reagent kit, effectively avoiding the phenomenon of reagent tube breakage, thus facilitating the transportation of reagent tubes. Another example is a reagent kit disclosed in Chinese Utility Model Patent Application No. CN202122462568.3, which includes a box body and a lid. The lid has a cavity for the box body to fit into. The box body has multiple arrayed reagent holes spaced apart, extending from the top to the bottom of the box body, allowing the reagents to protrude from the bottom of the box body. The reagent kit described in this solution adopts an embedded design, with the box body completely embedded in the lid, making it easy to assemble and disassemble. Only the bottom of the box body is exposed, so the reagent information can be observed from the exposed bottom of the box body without opening the lid or taking out the reagents one by one to obtain the reagent information, thus saving labor steps.

[0004] In common traditional reagent kit structures, test tubes and the kit body are usually molded as a single unit. Some kits, however, incorporate separate tubes for easy movement and observation. Because these tubes are independent tubular structures, transferring reagents or handling them can be difficult, easily leading to slippage and damage. Therefore, some kits connect the individual tubes for easier observation and transfer. However, the applicant has found that common reagent tubes, designed for transport and use, are typically made of materials with elastic deformation and corrosion resistance, such as PVC. But when these tubes are connected as a single unit, the PVC material forms independent connecting parts. This can cause bending and deformation at the joints when handling the vertically arranged tubes, leading to tilting and leakage. Conversely, using high-strength materials for the connecting parts makes it difficult to separate the tubes according to actual usage requirements.

[0005] To address the aforementioned issues, this invention provides a reagent kit with a special structure that enhances the connection strength between reagent tubes. This ensures that when batches of interconnected test tubes are moved, placed, and compared for observation, no deformation or leakage of internal reagent materials occurs, thereby improving the stability of the experimental process and guaranteeing the reliability of the experimental results. Utility Model Content

[0006] This invention provides a reagent kit product with a special structure that strengthens the connection between reagent tubes. This ensures that when batches of test tubes are arranged and connected, there will be no deformation or leakage of internal reagent materials during the process of moving, picking up, and comparing and observing, thereby improving the stability of the experimental process and ensuring the reliability of the experimental results.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A reagent kit for easy handling, placement, and comparative observation includes a support box at the bottom and a top cover plate installed on the upper part of the support box. The upper surface of the support box has a plurality of downward-recessed support positioning slots. A reagent tube assembly is disposed in the support positioning slots. The reagent tube assembly includes a plurality of test tubes that can be inserted into the support positioning slots. At least two adjacent test tubes are connected by a tube connection. A tube sealing cap is installed on the top of the test tubes. A sealing cap connection is formed between the tube sealing caps on the top of two interconnected test tubes.

[0008] As a preferred embodiment of the present invention, the tube connecting portion is located at the middle position of the test tube body.

[0009] As a preferred embodiment of the present invention, an annular reinforcing portion is further provided on the outer side of the tube body connection portion.

[0010] As a preferred embodiment of the present invention, a notch is provided on the sealing cap connection portion and the tube body connection portion.

[0011] As a preferred embodiment of the present invention, the end of the tube sealing cap protrudes outward to form an extension.

[0012] As a preferred embodiment of the present invention, the test tube body and the tube body sealing cap are made of PVC material.

[0013] As a preferred embodiment of the present invention, a downwardly protruding, annular locking sealing part is provided on the lower surface of the tube sealing cap.

[0014] As a preferred embodiment of the present invention, the lower part of the support positioning hole groove extends downward and penetrates the support box body, and when the test tube body is installed in the support positioning hole groove, its bottom protrudes downward from the support positioning hole groove.

[0015] As a preferred embodiment of the present invention, an inner support top is provided on the inner side of the upper cover plate for abutting against the upper surface of the outer periphery of the supporting box, and an outer support top is provided on the outer side of the supporting box for abutting against the lower surface of the upper cover plate.

[0016] In summary, this utility model can achieve the following beneficial effects: The reagent kit product described in this utility model, which facilitates easy handling, placement, and comparative observation, utilizes a structure where a tube connection is provided between two adjacent test tubes, and a sealing cap connection is provided between the tube sealing caps mounted on these two test tubes. This structure creates a stable frame structure after the tube sealing caps are installed on the test tubes. With this structure, even when multiple test tubes arranged in a straight line are simultaneously used to test the reagent samples stored inside, sufficient connection strength is maintained between the test tubes during handling and placement, preventing bending and shaking. This avoids leakage of internal reagent materials and also prevents vibration from affecting the test results. While ensuring the safety of the experimental process, it also improves the accuracy and stability of the experimental results. Attached Figure Description

Detailed Implementation

[0019] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0020] This solution is achieved through the following technical means: Example: In this example, a reagent kit product with a special structure that strengthens the connection between reagent tubes is provided. This ensures that when a batch of test tubes are arranged and connected, there will be no deformation or leakage of internal reagent materials during the process of moving, picking up, and comparing and observing, thereby improving the stability of the experimental process and ensuring the reliability of the experimental results.

[0021] Specifically, the reagent kit provided in this embodiment mainly comprises three parts: a support box 1, a top cover 2, and a reagent tube assembly 3 housed within the support box 1. (Refer to the attached instruction manual.) Figure 1The structure shown has a rectangular block-shaped support box 1. Several arrayed, downward-recessed support positioning slots 101 are formed on the support box 1. These slots 101 are cylindrical or frustum-shaped, with their radial dimensions gradually decreasing from top to bottom. The lower part of each slot 101 extends downward and penetrates the support box 1. A reagent tube assembly 3 for placing reagents and experimental samples is installed above the aforementioned support positioning slots 101. This reagent tube assembly 3 comprises several interconnected test tubes 301 and tube sealing caps 302.

[0022] The lower part of the test tube 301 is cylindrical or conical, corresponding to the shape of the aforementioned support and positioning slot 101, allowing it to engage and be fixed when inserted into the slot. At the center of each upright test tube 301, a circular reinforcing part 3022 is arranged around it, and a tube connecting part 3011 connects the circular reinforcing parts 3022 formed on adjacent test tubes 301. By alternately connecting several test tubes 301 and tube connecting parts 3011 in this manner, several test tubes 301 are arranged in a straight, elongated pattern. In this configuration, reagents can be placed into the inner cavity of each test tube 301 simultaneously during the experiment, and different types or concentrations of test samples can be added sequentially along the arrangement of the test tubes for observation.

[0023] Of course, in order to more accurately observe the reaction progress of the material at the bottom of the test tube 301 in real time without affecting the experimental reaction, the reagent tube assembly 3 can be made of transparent PVC material, and the lower part of the support positioning groove 101 can extend downward and penetrate the support box 1. Then, when the test tube 301 is installed in the support positioning groove 101, its bottom protrudes downward from the support positioning groove 101. Therefore, during the reaction experiment, simply placing the entire reagent kit on a transparent glass platform allows for accurate observation of the reaction at the bottom of the test tube from below.

[0024] It should be noted that in some biological experiments, it is sometimes necessary to seal and store reagent tubes containing samples in a specific temperature or pressure environment. Therefore, the reagent tube assembly 3 also includes a tube sealing cap 302 that covers the opening of each test tube 301. (Refer to the attached instruction manual.) Figure 4In the given structure, the tube sealing cap 302 is also made of PVC material, and its main body is a flat sheet. Several annular locking sealing parts 3025 are integrally formed on the lower surface of the tube sealing cap 302. The outer circumferential size of the locking sealing parts 3025 is slightly larger than the upper opening size of the aforementioned test tube body 301, and the arrangement of each locking sealing part 3025 corresponds to the position of each test tube body 301 mounted on the support box 1. Therefore, when the sample is placed into the test tube body 301, the connection and fixation between each test tube body 301 and the tube sealing cap 302 can be completed simply by squeezing and fastening.

[0025] It's important to clarify that the sealing caps 302 provided in this solution are not individually installed and fixed to each test tube 301. Instead, they are connected into a single structure via the sealing cap connector 3021. This design is necessary because if adjacent test tubes 301 were simply connected via the connector, when there are many connected test tubes 301 containing experimental reagents, the test tubes 301 would bend and sag downwards under gravity when the experimenter lifts the vertically aligned assembly. This bending and deformation becomes more pronounced towards the test tubes 301 further away from the lifting position, potentially leading to severe tilting and distortion at the far end. This not only causes the internal reagents to vibrate and shake, affecting the accuracy of experimental data obtained through observation and comparison, but also easily leads to spillage and leakage of internal materials from the cap opening.

[0026] In the structure presented in this solution, please refer to the appendix to the instruction manual. Figure 5 As shown in the schematic diagram, for two test tubes arranged adjacent to each other, when the upper tube sealing cap 302 simultaneously engages with the upper openings of the two test tube bodies 301, a double-layered frame structure is formed. When one end of the test tube body 301 tends to tilt downwards, the sealing cap connection 3021 exerts an inward pulling force, while the lower tube body connection 3011 provides an outward supporting force. This combined action, compared to a single-layer connection structure, more effectively resists deformation of the components. Furthermore, without affecting the insertion of the test tube body 301 into the supporting positioning slot 101, the strengthening effect of this structure increases with the vertical distance between the tube body connection 3011 and the sealing cap connection 3021.

[0027] The aforementioned annular reinforcing part 3022 can also provide higher structural strength in this case, preventing the test tube body 301 at the far end from sinking and tilting, while preventing the test tube body 301 itself from being squeezed, pulled and deformed.

[0028] As a preferred structure, to facilitate the easy separation of the tube sealing cap 302 from the openings of the individual test tubes 301 connected to it in one go, an extension 3024 can be formed at one end of the tube sealing cap 302 to allow the user to hold and pull it. After the experiment, when disassembling for cleaning or disposal, simply lifting and flipping this part upwards allows for quick and convenient separation of the two parts.

[0029] With the above structure, the assembly of the entire reagent kit is completed simply by closing and snapping the hollow cuboid top cover 2, which has an opening at the bottom, onto the support box 1 from top to bottom. More preferably, to prevent excessive compression of the reagent tube assembly 3 placed in the middle due to misoperation during the installation process, an inner support top 201 is provided on the inner side of the top cover 2 to abut against the upper surface of the outer periphery of the support box 1, and an outer support top 102 is provided on the outer side of the support box 1 to abut against the lower surface of the top cover 2.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
