Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a reagent box receiving basket.

[0002] The utility model also relates to an integrated reagent loading device. Background Art

[0003] In vitro diagnostic technology is a medical testing method that tests samples from organisms outside the body of the test subject to obtain clinical diagnostic information and diagnose diseases or body functions. Through the reaction between in vitro diagnostic reagents and biological samples, a qualitative or quantitative diagnosis can be given, and then compared with normal values ​​to determine the patient's physiological state. It is known as the "doctor's eyes" in the medical field and is an important component of modern laboratory medicine. In clinical applications, it runs through the entire process of disease treatment, including disease prevention, preliminary diagnosis, treatment plan selection, and efficacy evaluation. Currently, in vitro diagnostic technology can detect a wide range of items, and there are also many systems that can operate fully automatically. One of the prerequisites for the efficient operation of automated detection systems is the integration of efficient reagent loading. Ultimately, the collaborative operation of various functional units can complete tests such as enzyme immunoassay or molecular diagnosis.

[0004] In existing in vitro diagnostic equipment, the enzyme-linked immunosorbent assay (ELISA) workstation can fully automatically complete the ELISA test, including dilution, sample distribution, reagent distribution, incubation, plate washing, enzyme label reading, result printing and other steps. This requires the participation of a large number of various reagents, and the dosage and stability characteristics of different reagents vary greatly. Therefore, there will be reagent kits of different specifications. In order to achieve more efficient reagent kit loading, reagent kit loading with high versatility and simple structure is necessary. However, in fact, there are few solutions for efficient and fool-proof reagent kit addition. Basket or drawer structures are widely used in the efficient transportation of sample tube racks and reagent kits. The existing patent US5632388A discloses a solution for configuring array-type sample tube receiving holes in a basket, which can achieve the goal of reliably transferring multiple sample tubes without shaking. CN2196155 In the solution disclosed by 91U, multiple columns of sample tube rack receiving units are arranged side by side and detachably connected to the sample tube rack basket, so that batch loading of sample tubes can be realized, and the risk of shaking of the sample tube rack is small. Overall, the basket is a transport relay; AU2019398123B2 discloses an integrated reagent sample and consumables adding part, which is equipped with a foldable handle. The solution limits the detailed connection scheme of the handle and the main body, and limits the folding storage direction to one end of the sample tube receiving position, and the handle does not affect the opening and closing operation of the sample tube cover after storage; in enzyme-linked immunosorbent assay, manual addition of various types of test kits one by one is inefficient and has certain risks of contamination and placement errors. Therefore, loading the test kit in a modular basket and then adding it as a whole into the enzyme-linked immunosorbent assay workstation is a prerequisite for automation and efficiency.

[0005] In summary, designing a reagent kit basket that can be added individually or in modular groups to automated processing instruments, especially those compatible with enzyme-linked immunosorbent assay devices or workstations, requires a simple structure, high versatility of components, and strong replaceability, and the ability to operate with the equipment without interference during subsequent automated processing. This is a technical problem that needs to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to the accompanying drawings.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1

[0038] This embodiment provides a reagent box receiving basket, such as Figure 1 As shown, it includes a receiving part body, which is a groove-shaped structure with a predetermined depth. The groove-shaped structure is configured with a card block for matching the bar reagent kit. The bar reagent kit is received by the card block. The receiving part body is in the shape of an open rectangular parallelepiped or a quasi-rectangular parallelepiped. The receiving part body includes a bottom plate 1, and a handle plug-in portion 2 is provided in the middle of the bottom plate 1. The handle plug-in portion includes a plug-in slot. The plug-in slot is located in the middle of the bottom plate 1 and is arranged along the width direction of the basket. The two ends of the plug-in slot extend to the top of the two side walls of the receiving part body, as shown in FIG. Figure 2 and Figure 3The cam 2 of the handle 4 is fixed to the bottom of the handle 4 so that the handle 4 can be fixed to the handle 4 by the screw thread 21. The handle 4 is convenient to remove from the handle plug-in part 2, and the handle 4 can be easily removed from the handle plug-in part 2. The groove 5 is a hollow structure, which can diversify the processing procedures of the groove 5 and increase the dimensional accuracy of the molding. At the same time, due to the design of a detachable structure, the two can be independently processed and molded to adapt to different processing accuracy requirements. The detachable connection also makes it easier to replace and maintain the handle of the basket, and makes the cleaning and maintenance of the basket more convenient, the disinfection more thorough, and the risk of cross-contamination during long-term use is also lower. The top of the handle 4 is designed with a gripping portion 15 with an open side. This design gives the test kit basket a fool-proof operation feature. This design can clearly distinguish whether the loading direction of the basket is correct. In this embodiment, the materials of the handle 4 and the receiving part body are different. For example, the receiving part body is a non-metallic material, and the handle 4 is processed with a metal material. The receiving body can be injection molded with a non-metallic material with better injection molding properties. In this way, the processing cost is lower and the finished product precision is higher.

[0039] like Figure 4 and Figure 5As shown, the handle 4 divides the receiving part body into two receiving cavities. In this embodiment, the middle part of the bottom plate is selected as the plug-in point to plug the handle to form two receiving cavities with a symmetrical structure. The position of the handle can be adjusted and designed according to actual conditions. The size of the two receiving cavities formed is based on the size required for the actual application. In this embodiment, the two receiving cavities are respectively built-in with bar reagent box blocks, and the bar reagent box blocks undertake multiple bar reagent boxes. The application of long bar reagent boxes 6 in enzyme-linked immunosorbent assay is very extensive. For liquid reagents with large consumption, this type of reagent box is best used for loading. In this embodiment, the handle 4 can be plugged into the handle plug-in part 2 arranged in the middle of the bottom plate 1. At this time, multiple groups of opposing chimeric parts 3 can be locked to the bottom of the handle 4. The receiving part body includes a plurality of strip reagent box blocks distributed on both sides of the handle plug-in part 2. Here, the blocks are arranged in pairs on the side walls of the receiving part body in the width direction. Multiple strip reagent boxes are detachably clamped in the receiving part body. In this embodiment, the long strip reagent box 6 can be clamped in the groove of the basket receiving part body by an even number of blocks symmetrically distributed on both sides of the handle plug-in part 2. The even number of blocks can be 2, 4, 6, 8, etc. Here, the two ends of the long strip reagent box in the width direction are formed into a cylindrical structure, and the matching strip reagent box blocks also include an arc-shaped connecting surface, so that the long strip reagent box 6 can be efficiently and reliably stored in the basket.

[0040] Example 2

[0041] Example 2 replaces the function of the receiving cavity in Example 1; further explanation, the same parts are not repeated here, such as Figure 6-9As shown, the two receiving cavities of the reagent box receiving basket have built-in tube receiving blocks for receiving different types of reagent bottles. Reagents with smaller volumes added to the enzyme-linked immunosorbent assay are generally stored in cylindrical bottles, which can be a common form of small system reagent boxes that need to be added. The volumes of reagent bottles produced by different manufacturers vary greatly. In order to match the differences in reagent bottles in automated detection equipment, some equipment requires the operator to pour the reagents in the original reagent bottles into standard reagent bottles, and then add them to the automated detection equipment. This operation is highly complex, has redundant and inefficient work, and poses a risk of contamination to the operator. In this embodiment, the receiving part body also includes two tube receiving blocks 7 distributed on both sides of the handle plug-in part 2. The two tube receiving blocks 7 are configured with the same structure and are symmetrically and detachably installed in the groove of the receiving part body, that is, in the two receiving cavities. The tube receiving block 7 contains a plurality of connecting holes 8 arranged in an array. The number of connecting holes 8 here can be 4×6=24, or 4 ×8=32, or other forms of row and column arrangement. In one case, the connecting hole 8 can be arranged as a single aperture structure with a preset depth, so that it can accommodate reagent bottles of the same size. In another case, the connecting hole 8 can include at least two coaxial connecting parts with different diameters. Here, two coaxial connecting parts are taken as an example. Some holes of the arrayed connecting holes 8 accommodate the first reagent bottle 9 with a larger diameter, while the other holes accommodate the second reagent bottle 10 with a smaller diameter. The connecting part with a smaller diameter extends a greater distance in the tube receiving block 7 than the connecting part with a larger diameter. A transition platform is included between adjacent connecting parts of unequal diameters. The transition platform is used to confine the first reagent bottle 9 to the larger diameter connecting part above the transition platform, while the second reagent bottle 10 is constrained by the smaller diameter connecting part. Such a design enables the arrayed connecting holes 8 to reliably accommodate different types of reagent bottles, making the identification features more obvious and the control accuracy higher in subsequent operations.

[0042] Example 3

[0043] like Figure 10-12As shown, the present embodiment provides an integrated reagent loading device, including a loading body 11, which can be configured as a roughly rectangular structure. In order to ensure that its strength meets the requirements, the loading body 11 is processed using metal materials, such as stainless steel or alloy materials. A plurality of receiving slots 12 are provided on the loading body 11. The number of receiving slots 12 here can be no less than 2 and no more than 6 to ensure loading efficiency and reduce the operational difficulty of integrated loading. Each receiving slot 12 is configured with the same structure to make processing more convenient. An anti-reverse installation structure is also configured in each receiving slot 12. Each receiving slot 12 can detachably receive a fool-proof reagent kit receiving basket in Example 1 or Example 2, and the opening ends of the handle gripping portions 15 in the multiple reagent kit receiving baskets are oriented in the same direction, so that The operator can visually and autonomously restrain the installation of the reagent reagent receiving basket, and can also cooperate with the anti-reverse installation structure to achieve reliable physical restraint, so that the basket cannot be embedded in the receiving slot in the reverse state, which has a double protection effect. In this embodiment, the bottom of the loading main body 11 is also provided with an opposing side guide portion 13. In this embodiment, the cross-section of the side guide portion 13 is L-shaped. The automated detection system can be provided with a guide structure that cooperates with the side guide portion 13. Specifically, the system is provided with a plurality of relatively arranged guide blocks 14. The guide blocks 14 are configured as standard parts to make processing more convenient. The integrated reagent loading device can rely on the L-shaped cross-section side guide portion 13 to cooperate with the guide block 14, so that the integrated reagent loading device can be reliably pushed into place with low resistance, and its installation operation is also simpler.

[0044] Example 4

[0045] In this embodiment, the application of the above-mentioned embodiments in a biological sample processing system is provided, especially an ELISA enzyme-linked immunosorbent assay (ELISA) automatic detection system. The system includes a reagent receiving portion, which can receive the fool-proof reagent kit receiving baskets of Examples 1 and 2. The reagent kits are arranged in the reagent kit receiving baskets. The system also includes a sample tube receiving portion, which can accommodate multiple groups of sample tube racks. Here, the sample tube racks can be single-row sample tube racks, and each sample tube rack can contain 8, 9, 10, 11, 12, and so on, sample tubes. In combination with the integrated reagent loading portion of Example 3, all relevant reagents can be efficiently and quickly prepared at one time.
