[0002] Chemiluminescent immunoassay is an emerging analytical method that combines magnetic separation technology, chemiluminescence technology and immunoassay technology. It is widely used in hospital clinical diagnosis and other fields because of its advantages such as high accuracy, high sensitivity, short detection time, wide detection range and no pollution.

[0003] The physical structure of a chemiluminescent immunoassay analyzer usually includes several modules, such as a reagent system, a sample addition system, a washing system, and an incubation system. The role of the reagent system is to provide the reagent components required for detection to the analyzer.

[0004] In the prior art, the reagent system includes a reagent compartment, in which a circular reagent tray is rotatably arranged, and a plurality of reagent racks are placed on the reagent tray, and one reagent rack corresponds to one test item. As the reagent tray rotates in the reagent compartment, the reagent components can be provided to the inside of the chemiluminescent immunoassay analyzer. At present, the reagent rack supporting the chemiluminescent immunoassay analyzer is usually provided with three slots, that is, three-component reagents are provided for the test items. However, with the increase in the demand for detection, the reagent components required are different according to the different test items, and some test items require four-component reagents. If independent three-component reagent racks and four-component reagent racks are to be produced for different component reagents, the cost will inevitably increase, and at the same time, the original reagent tray is also not compatible with the four-component reagent rack. Therefore, the structure of the reagent rack and the reagent layout on the reagent tray need to be further optimized. Utility Model Content

[0029] The utility model is further described below in conjunction with embodiments and drawings.

[0030] like Figure 1 As shown, a reagent rack assembly includes a basic reagent rack 1 and an extended reagent rack 2, wherein the basic reagent rack 1 is a strip-shaped structure, and the basic reagent rack 1 is provided with three basic installation holes 1a distributed along a linear direction, and the three basic installation holes 1a all extend along the height direction of the basic reagent rack 1, and the extended reagent rack 2 is provided with an extended installation hole 2a extending along the height direction, and the extended reagent rack 2 is detachably mounted on one side of the basic reagent rack 1. The basic installation hole 1a and the extended installation hole 2a are both used to place reagent bottles (refer to Figure 5 ).

[0031] Based on the above structural design, by designing the basic reagent rack 1 and the extended reagent rack 2 to be detachably connected, in terms of production and manufacturing, it is only necessary to produce a basic reagent rack 1 with three mounting holes and an extended reagent rack 2 with a single mounting hole, which can reduce costs and simplify production steps; in terms of use, a basic reagent rack 1 with three mounting holes can be selected according to detection requirements, or the basic reagent rack 1 can be expanded into a reagent rack with four mounting holes by matching the extended reagent rack 2, which meets the storage requirements of three-component or four-component reagents during the detection process, and has the technical advantages of easy installation, strong versatility and low cost.

[0032] In this embodiment, the extended reagent rack 2 is located on one side of the basic reagent rack 1 in the width direction. Preferably, the extended reagent rack 2 is arranged in the middle of one side of the basic reagent rack 1 in the width direction, corresponding to the middle position of the three basic installation holes 1a.

[0033] Furthermore, Figure 1 and 2 As shown, a hanging portion 11 is provided on one side of the width direction of the basic reagent rack 1, and a hanging buckle 21 adapted to the hanging portion 11 is provided on the side of the extended reagent rack 2, so as to facilitate the detachable installation of the extended reagent rack 2 on one side of the basic reagent rack 1. The hanging portion 11 is located between two adjacent basic installation holes 1a, which can ensure the integrity of the accommodation space of each basic installation hole 1a.

[0034] Please refer to Figure 3 The hanging part 11 includes a hanging hole 111 located at the upper part of the basic reagent rack 1, and a positioning hole 112 is provided on the side wall of the hanging hole 111 close to the outer side. Figure 4It can be seen that a locking tongue 211 is provided at the lower end of the hanging buckle 21. When the hanging buckle 21 is inserted downward into the hanging hole 111, the locking tongue 211 at the end of the hanging buckle 21 can be buckled into the positioning hole 112. At this time, the upper surface of the extended reagent rack 2 is flush with the upper surface of the basic reagent rack 1. Such a design can effectively prevent the extended reagent rack 2 from falling off.

[0035] In order to further enhance the reliability of the connection between the extended reagent rack 2 and the basic reagent rack 1, Figure 3 and 4 The lower part of the basic reagent rack 1 docking the extended reagent rack 2 is provided with a snap-on hole 12, and the lower part of the extended reagent rack 2 is provided with a snap 22 matching the snap-on hole 12. In this way, both the upper and lower ends of the extended reagent rack 2 can be fixedly connected to the basic reagent rack 1.

[0036] like Figure 6 As shown, this embodiment also provides a reagent layout structure based on the above reagent rack assembly, including a tray 3, on which a clamping structure is distributed along the circumference, and a reagent rack assembly is detachably placed on the clamping structure, that is, the tray 3 can hold multiple basic reagent racks 1, or can hold multiple basic reagent racks 1 with extended reagent racks 2. With such a design, the tray 3 can be compatible with reagent racks for three-component reagents and reagent racks for four-component reagents, and at the same time meets the needs of storing three-component or four-component reagents, so as to meet the project detection of different detection needs, and has the advantages of strong practicality and high compactness.

[0037] Furthermore, Figure 6 As shown, the tray 3 is a circular tray, and the positioning structure includes first mounting grooves 4 distributed along the circumference array, and the first mounting grooves 4 are used to vertically place the basic reagent rack 1, so that the centers of the three basic mounting holes 1a on the same basic reagent rack 1 are located on the same radius. A second mounting groove 5 is provided between two adjacent first mounting grooves 4, and the second mounting groove 5 is used to place the extended reagent rack 2 attached to the side of the basic reagent rack 1. With such a design, refer to Figure 7 and Figure 8 Whether the test project requires a three-component reagent or a four-component reagent, the tray 3 is compatible.

[0038] Please refer to Figure 6, the space surrounded by the inner sides of the two adjacent first mounting grooves 4 is a fan-shaped structure, and the second mounting groove 5 is preferably located in the middle of the fan-shaped structure. Designed in this way, the compactness of the structure can be improved and the space utilization rate can be increased. Another convenience is that the expansion reagent rack 2 is designed in the middle of one side of the width direction of the basic reagent rack 1, and after the expansion reagent rack 2 is installed on the basic reagent rack 1, the upper surfaces of the two reagent racks are flush. The advantage of such a design is that when the reagent structure on the layout tray 3 is not required to expand the diameter of the tray 3, the expansion reagent rack 2 can be compatible, and at the same time, the height of the overall structure will not be increased, which is conducive to the compact and miniaturized design of the product.

[0039] Further, refer to Figure 6 , a third mounting groove 6 is also provided in the fan-shaped space surrounded by two adjacent first mounting grooves 4, and the third mounting groove 6 is located outside the second mounting groove 5, and is used to place a liquid consumable bottle 7. When the liquid consumable bottle 7 and the basic reagent rack 1 with the extended reagent rack 2 are placed on the tray 3, the center lines of the reagent bottles inside each basic reagent rack 1 are located on the same circumference, the reagent bottles in the middle of each basic reagent rack 1 and the reagent bottles on each extended reagent rack 2 are located on the same circumference, and the reagent bottles outside each basic reagent rack 1 and each liquid consumable bottle 7 are located on the same circumference. With such a layout, consumable stations are added, and more reagent bottles can be installed on the tray 3 as much as possible, which improves the space utilization rate and makes the structural layout more reasonable and compact.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
