Description

Technical Field

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

[0002] In vitro diagnostic reagent packaging typically serves to buffer and secure the core reagents inside. Early in vitro diagnostic kits usually only contained three types of test tubes: core reagents, negative controls, and positive controls. However, with the rapid development of the in vitro diagnostics field, high throughput, high sensitivity, quantitative detection, and even the integration of large-scale model algorithms for disease risk prediction have become new market demands. These higher-level market demands have placed new requirements on in vitro diagnostic reagents. Higher throughput demands have led to more complex and diverse core reagents, making them easier to assemble and disassemble. Higher sensitivity and quantitative detection requirements have placed greater challenges on the detection performance of core reagents and the packaging, requiring greater protection against drops, high temperatures, freezing, and contamination. Conventional in vitro diagnostic reagent packaging can only provide simple buffering and securing through internal core buffer modules. In cases of complex and diverse configurations of core reagents, simple and intuitive reagent tube differentiation is often achieved by differentiating the color of the tube caps. Furthermore, when core reagent tubes and positive control tubes are placed in the same space, cross-contamination can occur under extreme conditions or due to improper handling, such as improperly tightened caps, directly affecting the accuracy of test results. Improvements are needed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a reagent kit that allows for the storage of different reagents in different compartments, thereby avoiding confusion that could affect detection accuracy, and is also convenient for handling and operation.

[0004] To achieve the above objectives, this utility model provides a test kit, including a box body and a box cover. The box body is provided with at least a first chamber and a second chamber. A first tray and a second tray are respectively disposed in the first chamber and the second chamber. The first tray and the second tray are movably connected to the first chamber and the second chamber, respectively. Different reagent tubes are contained in the first tray and the second tray.

[0005] The lid is movably connected to the box body, and the lid can close the openings of the first chamber and the second chamber so that when the lid is not opened, the first tray is confined in the first chamber and the second tray is confined in the second chamber.

[0006] The lid has multiple sequentially connected mating surfaces. These mating surfaces can rotate relative to each other at the connection points. When the lid is opened, the mating surfaces can unfold, serving as an auxiliary support structure during operation.

[0007] Furthermore, the first chamber and the second chamber are arranged in upper and lower layers, and both the first tray and the second tray are taken out from the side of the box.

[0008] Furthermore, labels that can distinguish different reagents are provided at preset positions on the first tray and the second tray.

[0009] Furthermore, the external dimensions of the first tray and the second tray are respectively clearance-fitted with the first chamber and the second chamber.

[0010] Furthermore, in the side of the box body, the side where the openings of the first chamber and the second chamber are located is the first side of the box body, and the side of the box body opposite to the first side is the second side. The box lid includes a first fitting surface, a second fitting surface, and a third fitting surface connected in sequence. The first fitting surface is hinged to the second side of the box body and can rotate relative to the box body. The second fitting surface corresponds to the top surface of the box body, and the third fitting surface corresponds to the first side of the box body.

[0011] Furthermore, the edge of the third sealing surface is detachably connected to the first side of the box body using Velcro or snap fasteners.

[0012] Furthermore, the interior of the box is also provided with thermal insulation material, which wraps the areas where the first chamber and the second chamber are located.

[0013] Furthermore, both the first tray and the second tray are provided with a support plate, and the support plate is provided with a plurality of support holes, which are used to support and limit the reagent tube.

[0014] Furthermore, the support plate is arranged parallel to the bottom surface of the first tray and the second tray, and the support holes are arranged in a rectangular array on the first tray or the second tray.

[0015] Furthermore, the support plate is provided with an elastic buffer structure, which is in contact with the reagent tube.

[0016] The above-mentioned solution of this utility model has the following beneficial effects:

[0017] The test kit provided by this invention allows for the separate storage of different reagents within the box through different chambers, avoiding confusion and ensuring accuracy when large quantities are taken out. The tray-type extraction method facilitates the placement and removal of reagent tubes. The lid not only facilitates opening and closing but also serves as an auxiliary support structure when opened. The insulation material filling the box maintains a low-temperature environment for a period after cold chain transportation, while the support plate and elastic cushioning structure in the tray minimize the risk of reagent tube breakage and leakage during transportation and handling. Therefore, the overall reliability and convenience of the test kit in terms of transportation and use are improved.

[0018] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0026] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-3 As shown, an embodiment of this utility model provides a test kit, including a box body 1. The box body 1 is divided into a first chamber 3 and a second chamber 4 by a partition 2 in the middle. For example, in this embodiment, the partition 2 is arranged parallel to the operating table, that is, after the box body 1 is placed on the operating table, the partition 2 is also parallel to the operating table, so as to divide the box body 1 into upper and lower layers. The first chamber 3 and the second chamber 4 are respectively provided with a first tray 5 and a second tray 6. Both the first tray 5 and the second tray 6 are movable relative to the first chamber 3 and the second chamber 4, so that the first tray 5 and the second tray 6 can be pulled out from the box body 1. Therefore, when the first tray 5 and the second tray 6 contain different reagents, the different reagents can be distinguished. For example, the first tray 5 contains reagent A and the second tray 6 contains reagent B, or the first tray 5 contains a positive control sample and the second tray 6 contains a negative control sample. During testing, when reagent A or a positive control sample is needed, the first tray 5 can be removed from box 1, and then the corresponding reagent tube 7 can be taken. When reagent B or a negative control sample is needed, the second tray 6 can be removed from box 1, and then the corresponding reagent tube 7 can be taken. This operation avoids confusion between different reagents. When taking a large number of reagent tubes 7 from the same box 1, it is only necessary to confirm whether the first tray 5 or the second tray 6 has been removed to accurately distinguish between different reagents. When taking one type of reagent tube 7 and needing to take another type, simply put the previously removed tray back and then remove the other tray. This better avoids confusion during large-scale testing.

[0030] In actual use, different colored labels can be affixed to prominent positions on the first tray 5 and the second tray 6 to facilitate quick differentiation by users. It should be noted that, considering the actual depth of the reagent tubes 7, this embodiment adopts a top-bottom layered structure inside the box 1. For other, deeper reagent tubes 7, it is also possible to consider setting the inside of the box 1 to a left-right layered structure, that is, the partition 2 is perpendicular to the operating table, to accommodate even deeper reagent tubes 7.

[0031] In this embodiment, both the first tray 5 and the second tray 6 are square-shaped, meaning they each include a bottom surface and four sides, with the top surface open. Therefore, reagent tubes 7 can be placed in either the first tray 5 or the second tray 6. When the first tray 5 and the second tray 6 are located inside the first chamber 3 and the second chamber 4, respectively, they can seal the openings of the first chamber 3 and the second chamber 4, creating a relatively sealed environment inside the first chamber 3 and the second chamber 4, ensuring a relatively stable environment for reagent storage and transportation.

[0032] It should be noted that the box body 1, the first tray 5, and the second tray 6 can be made of materials commonly used in existing test kits, such as cardboard or plastic, with relatively smooth surfaces. Therefore, the first tray 5 and the second tray 6 can be smoothly removed from the first chamber 3 and the second chamber 4, and their insertion into the first chamber 3 and the second chamber 4 is also relatively convenient. The overall dimensions of the first tray 5 and the second tray 6 are set to be slightly smaller than the overall dimensions of the first chamber 3 and the second chamber 4, so that the first chamber 3 and the second chamber 4 can respectively accommodate the first tray 5 and the second tray 6, and the insertion of the first tray 5 and the second tray 6 into the first chamber 3 and the second chamber 4 is relatively smooth without significant jamming. Of course, the overall dimensions of the trays should not be too small compared to the chambers to avoid the trays shaking relative to the chambers during handling and transportation, which could cause damage to the reagent tubes 7 due to impact forces. Considering that the reagent tubes 7 placed on the upper and lower layers are usually the same size, in this embodiment the size of the first tray 5 and the second tray 6 are set to be the same to maintain the same size for easy manufacturing. Correspondingly, the first chamber 3 and the second chamber 4 also maintain the same size, that is, the upper and lower layers are uniformly separated.

[0033] As described above, in this embodiment, the first tray 5 and the second tray 6 are respectively movably disposed in the first chamber 3 and the second chamber 4, and their contact with each other is relatively smooth. In order to prevent the first tray 5 and the second tray 6 from sliding directly out of the corresponding chamber, this embodiment further provides a box cover 8 on the box body 1. The box cover 8 covers the openings of the first chamber 3 and the second chamber 4 so that the trays will not slide out of the corresponding chambers when the box cover 8 is not opened.

[0034] It should be noted that, considering the upper and lower layer arrangement of the first chamber 3 and the second chamber 4, in this embodiment, the openings of the first chamber 3 and the second chamber 4 are defined as the first side of the box body 1, and the side opposite to the first side is defined as the second side. The box body 1 connects the first side and the second side through its top surface. In one specific embodiment, the lid 8 is configured to be movably connected to the box body 1. Specifically, the lid 8 includes a first mating surface 801, a second mating surface 802, and a third mating surface 803 arranged sequentially. The connection points between the first mating surface 801 and the second mating surface 802, and between the second mating surface 802 and the third mating surface 803, are all provided with pleats (or other soft material) to allow relative rotation between them. Simultaneously, the first mating surface 801 is hinged to the second side of the box body 1, enabling it to rotate relative to the box body 1. The second mating surface 802 has the same dimensions as the top surface of the box body 1, and the third mating surface 803 corresponds to the opening in the first side of the box body 1. When the lid 8 is closed, the third mating surface 803 of the lid 8 fits against the first side of the box body 1, closing the opening. At the same time, the second mating surface 802 fits against the top surface of the box body 1, and the first mating surface 801 fits against the second side of the box body 1, thus completely closing the box body 1 while ensuring structural compactness. The edge of the third mating surface 803 can be fixed to the first side of the box body 1 using Velcro 9, or it can be fixed using clips, etc., to ensure that the lid 8 remains secure after closing.

[0035] It is worth mentioning that, in this embodiment, the lid 8 can serve as an experimental support after being opened, assisting in supporting experimental apparatus or reagent tubes 7, etc. Specifically, after the lid 8 is opened, it is located on one side of the box body 1, and the third mating surface 803 of the lid 8 (which can also be folded to a certain extent) rests on the worktable, so that the second mating surface 802 of the box body 1 (or together with the first mating surface 801) serves as a support surface to support the experimental apparatus or reagent tubes 7, etc. The second mating surface 802 of the box body 1 can be provided with a suitable slot or the like to assist in the support. In addition, an explanatory area can be further provided at a suitable location on the lid 8 or the box body 1, on which text can be pasted or printed to provide a brief explanation of the reagents or operating procedures, facilitating operation by the user.

[0036] Of course, in other embodiments, the lid 8 can also be detachably connected to the box body 1, for example, by directly and completely covering the box body 1, which can also achieve the purpose of covering the chamber opening and restricting the tray from sliding out. In addition, the lid 8 can also further improve the sealing of the openings of the first chamber 3 and the second chamber 4, ensuring the stability of the internal environment.

[0037] As mentioned in the background art, test kits typically require transportation, and this transportation must be carried out at low temperatures (e.g., -20°C). Therefore, in this embodiment, the interior of the box 1 (excluding the areas where the first chamber 3 and the second chamber 4 are located) is also equipped with insulation material. This insulation material can enclose the first chamber 3 and the second chamber 4, keeping the reagents in the first tray 5 and the second tray 6 inside at a low temperature. This ensures that the low temperature environment is maintained for a period of time during the brief handling process after leaving the cold chain, preventing reagent failure, etc., and allowing unused reagents to be quickly returned for subsequent storage in a refrigerator. The openings of the first chamber 3 and the second chamber 4, sealed by the first tray 5 and the second tray 6, are also filled with insulation material, thus ensuring that the first chamber 3 and the second chamber 4 are completely insulated.

[0038] In addition, during transportation, the test kits must be protected from impacts and damage to the test tubes (7), and should not be flipped over, as this could cause the stoppers to loosen or come off, leading to leakage. Also, if... Figure 4 , Figure 5 As shown, in this embodiment, a support plate 10 is provided in the first tray 5 and the second tray 6, and the support plate 10 is provided with multiple support holes 11 arranged in a rectangular array. The reagent tubes 7 are supported and limited through the support holes 11. The support plate 10 is parallel to the bottom surface of the first tray 5 and the second tray 6, and preferably located slightly above the center of the first tray 5 and the second tray 6, so that after the reagent tubes 7 are placed through the support holes 11, they are (as vertical as possible) relative to the bottom surface of the tray. That is, when the test kit is placed upright, the reagent tubes 7 remain vertical, thereby better preventing the tube stoppers of the reagent tubes 7 from loosening and falling out, or leakage. At the same time, the support holes 11 can separate the reagent tubes 7 to a certain extent, thereby minimizing the collision between the reagent tubes 7. It can be understood that this vertical method of taking the reagent tubes 7 out of the tray is more convenient for hand operation than horizontal method.

[0039] To further prevent reagent tube 7 from being damaged or leaking due to hard impacts during transportation, an elastic buffer structure is provided on the support plate 10 in this embodiment. The elastic buffer structure allows the reagent tube 7 to be subjected to a certain elastic force, so that the reagent tube 7 can be elastically buffered when the box 1 shakes, thereby further preventing the reagent tube 7 from being damaged by hard impacts.

[0040] In one specific embodiment, the support plate 10 is entirely hollowed out, with each support hole 11 forming a support ring. These support rings are supported by support blocks; for example, each support ring is supported in a cross shape by four support blocks, as shown in the figure. Because the support plate 10 is made of a material with a certain degree of elasticity (such as rigid plastic), it can provide elastic support for the reagent tube 7, achieving a certain degree of elastic cushioning. In another specific embodiment, some positions of the support holes 11 are provided with a flexible, elastic material. This flexible material directly contacts the reagent tube 7, providing elastic support and similarly achieving a certain degree of elastic cushioning. Furthermore, the positions where the first tray 5 and the second tray 6 support the bottom of the reagent tube 7 can also be provided with grooves and filled with flexible, elastic material, so that the bottom of the reagent tube 7 can also receive elastic support.

[0041] In summary, the test kit provided in this embodiment allows for the separate storage of different reagents through different chambers within the box 1, avoiding confusion and affecting test accuracy when large quantities are taken out. At the same time, the tray extraction method facilitates the placement and removal of reagent tubes 7. The box lid 8 is not only easy to open and close, but also serves as an auxiliary support structure when opened. In addition, the insulation material filled in the box 1 can maintain a low temperature environment inside the box 1 for a period of time after cold chain transportation. The support plate 10 and elastic buffer structure in the tray also minimize the risk of reagent tube 7 breakage and leakage during transportation and handling.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
