Description

Technical Field

[0001] This utility model relates to the field of specific protein detection technology, specifically to a dilution pan used in a specific protein analyzer. Background Technology

[0002] In the detection of specific proteins, some samples can be detected directly after adding reagents, but others require dilution before accurate measurement because the target protein concentration is too high, exceeding the instrument's linear detection range. Currently, most specific protein analyzers lack an onboard independent dilution module, and sample dilution is usually performed manually outside the instrument, or by temporarily using a portion of the reaction tray as a dilution container.

[0003] However, the above operation still has some shortcomings: if manual dilution is used, it will not only increase the workload of operators, but also easily lead to deviations in test results due to operational errors (such as inaccurate dilution ratio or cross-contamination); if dilution is carried out using the dilution cup in the reaction plate, it will occupy the channel originally used for detection, interfere with the main detection sequence, reduce detection efficiency, and thus affect the overall automated analysis efficiency of the machine. Utility Model Content

[0004] The technical problem to be solved by this invention is to provide a dilution tray for a specific protein analyzer, which can flexibly perform stepwise cyclic dilution of samples without affecting the main timing of the reaction unit, thus ensuring the continuity of detection and improving detection efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dilution tray for a specific protein analyzer, including a dilution tray body, the dilution tray body including an outer tray and an inner tray disposed inside it, the outer tray and the inner tray can rotate relative to each other, the outer tray is provided with a first placement component for placing multiple dilution cups and a second placement component for placing a container structure along its circumference, and the inner tray is provided with multiple third placement components for placing reagent bottles.

[0006] Explanation: The dilution tray has a sample dispensing mechanism on one side for performing sample dilution and reagent addition operations. The sample dispensing mechanism is existing technology, and the container structure is used to hold antigen detection solution, diluent, or sample.

[0007] Compared with existing technologies, the advantages of this solution are as follows: It integrates the dilution cup, container structure, and reagent bottle into a single dilution tray. Through the coordinated rotation of the outer and inner trays, precise positioning and docking between the dilution cup, container structure, and reagent bottle can be achieved. This facilitates the sequential completion of sample dilution and reagent addition operations by the sample addition mechanism, eliminating the need for manual dilution. This not only reduces workload but also results in a compact structure and high space utilization. Furthermore, the dilution operation is completed independently on the dilution tray, eliminating the need to operate on the reaction tray. This avoids occupying the detection position of the reaction cup on the reaction tray, allowing for flexible sample dilution without affecting the main timing sequence of the reaction unit, ensuring the continuity of detection, and thus improving detection efficiency.

[0008] In a preferred embodiment of this utility model, both the first placement component and the second placement component are detachably connected to the outer disk.

[0009] The beneficial effects of this solution are as follows: After the test is completed, the operator can directly remove the first and second placement components from the outer plate as a whole, and remove multiple dilution cups and containers at once, avoiding the tedious operation of removing the containers one by one in the traditional method, thus improving efficiency; different types of containers (such as dilution cups and antigen test tubes) are set in independent detachable components, realizing functional zoning and modular management, which not only helps the operator to quickly identify and handle them, but also facilitates subsequent cleaning, disinfection or replacement.

[0010] In a preferred embodiment of the present invention, the outer disk is provided with a plurality of first mounting holes spaced apart along its circumference. Along the circumferential direction of the first placement component, one end of the first placement component is provided with a plurality of second mounting holes that can match the positions of the first mounting holes, and the other end is provided with a plurality of placement sleeves for placing dilution cups.

[0011] The beneficial effects of this solution are as follows: By precisely matching the first mounting hole and the second mounting hole, the first placement component can be firmly fixed to the outer plate using bolts or other fasteners, ensuring that it does not loosen or shift during the high-speed rotation of the dilution plate body, thus guaranteeing stable operation and sample addition accuracy. After the test is completed, the first placement component can be removed from the outer plate by loosening the screws. Both installation and disassembly are relatively convenient.

[0012] In a preferred embodiment of the present invention, the first placement component includes a first connecting plate and a placement plate arranged in a stepped manner, the second mounting hole is disposed on the first connecting plate, and the placement sleeve is disposed on the placement plate.

[0013] The beneficial effects of this solution are: the upper side of the placement plate is lower than the upper side of the first connecting plate, forming a height difference, so that the body of the dilution cup is located on the lower plane, effectively avoiding the sample dispensing mechanism, cleaning mechanism and other moving parts, and reducing the risk of mechanical interference during operation.

[0014] In a preferred embodiment of this utility model, an extraction block is provided in the middle of the upper side of the placement plate near the end of the first connecting plate.

[0015] The beneficial effects of this solution are: when the first placement component needs to be removed after the test, it can be removed by holding the extraction block, which is more convenient than picking up the first placement component by holding the edge of the first connecting plate; the extraction block is located in the middle, which can ensure its stability during the extraction of the first placement component.

[0016] In a preferred embodiment of the present invention, the second placement component includes multiple placement seats of different sizes for placing different holding structures.

[0017] The beneficial effects of this solution are: different containers can be placed in different placement seats, and each container can hold different liquids, such as antigen detection solution, diluent, and sample, which can avoid mixing up containers containing different liquids.

[0018] In a preferred embodiment of the present invention, the third placement component includes a plurality of baffles evenly spaced on the inner plate, with a first receiving groove for placing reagent bottles between two adjacent baffles, and a second receiving groove provided on the side of each baffle away from the first receiving groove, the size of the second receiving groove being different from the size of the first receiving groove.

[0019] The beneficial effects of this solution are as follows: Clinical testing often requires the use of various reagents with different packaging specifications (such as 5mL, 10mL, 15mL, etc.) and bottle sizes. This solution, by setting up first and second receiving slots of different sizes, can simultaneously accommodate standard and non-standard bottles, as well as small and large volume bottles, significantly improving the compatibility of the dilution tray with different reagent types and meeting the needs of parallel testing of multiple items and reagents. Traditional designs usually only set up receiving slots of a single specification between baffles, resulting in some space being idle or not being fully utilized. This solution significantly improves the reagent storage density per unit area without increasing the overall volume of the inner tray, achieving capacity expansion within a limited space.
