[0025] To make this utility model clearer and more understandable, the following detailed description of the utility model is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the given embodiments are merely one implementation method and do not represent all embodiments.

[0026] Example 1

[0027] Combination Figures 1-7 This embodiment provides a small, fully automated blood typing analyzer that is easy to transport and install. It includes a cabinet 1, with a touchscreen display 17 on the outer surface of the cabinet 1. A card slot 15 is provided on the side of the cabinet 1. A workbench 2 is located inside the cabinet 1, and a cabinet door 16 is provided on the cabinet 1 corresponding to the workbench 2. A sample loading module 3 is suspended above the workbench 2. Along its length, the workbench 2 is equipped with a pipette tip holder 4, a reagent holder 5, a diluent holder 14, a shaking and refrigeration unit 13, and a gel holder 8. A heating module is located behind the gel holder 8. The unit comprises a puncture module 10, a reading port 11, and a discard card slot 12. The discard card slot 12 is located near the edge of the workbench 2 and is connected to the card dropping port 15. The reading port 11 is located on the side of the discard card slot 12 away from the workbench 2 and penetrates the workbench 2. A reading module 7 is fixed on the back of the workbench 2 near the reading port 11. A centrifugal module 6 is provided behind the heating module 9. The upper part of the centrifugal module 6 is engaged with the workbench 2, and the lower part of the centrifugal module 6 extends to the bottom plate of the cabinet 1 and is fixed thereto.

[0028] In this embodiment, the workbench 2 is arranged from left to right along its length as follows: pipette tip holder 4, reagent holder 5, diluent holder 14, shaking and refrigeration unit 13, and gel holder 8. Behind the gel holder 8, from left to right, are arranged a heating module 9, a puncture module 10, a reading port 11, and a waste card slot 12. Specifically, the pipette tip holder 4, reagent holder 5, and diluent holder 14 are detachably connected to the workbench 2 via guide assemblies, while the shaking and refrigeration unit 13, gel holder 8, heating module 9, and centrifugation module 6 are fixedly connected to the workbench 2. The gel holder 8 contains reagent cards. The gel holder 8 serves as the initial sample positioning point; its position determines the sample addition accuracy of the sample addition module 3. Fixed installation avoids positional errors caused by manual adjustment. After sample addition via puncture, the reagent card needs to be incubated in the heating module 9. After incubation, it must be precisely transferred to the centrifugation module 6. These three components are closely interconnected, and their fixed installation ensures a strict relative position in their mechanical structure, preventing positioning deviations caused by disassembly. The pipette tip holder 4, reagent holder 5, and diluent holder 14 are disposable pipette tips 305 and test reagents, and their detachable design facilitates replacement and replenishment. The interpretation module 7 is located on the back of the workbench 2, reducing unnecessary space occupation. The sample addition module 3 delivers the reagent card to the interpretation module 7 for interpretation via the interpretation port 11. Therefore, the workbench 2 essentially separates the consumables area on the left from the core functions on the right, satisfying the need for a compact layout in a miniaturized design while achieving efficient collaboration of the testing process through functional zoning. It should be noted that in this embodiment, the touch screen 17 and the cabinet door 16 are set on the same side of the cabinet body 1 for easy use. The cabinet door 16 is provided with a handle to facilitate opening the cabinet door 16. In this embodiment, the guide group is a pair of guide plates that are arranged oppositely to the protruding worktable 2 and are snapped into a detachable carrier to guide its installation.

[0029] Specifically, the periphery of the reading port 11 is provided with a reading cover 19 protruding from the worktable 2, which has a guiding function. The reading module 7 includes a scanning head 701, a first light source 702, and a second light source 703 located on the same straight line. The first light source 702 and the second light source 703 are arranged opposite each other on both sides of the reading port 11, with the scanning head 701 positioned close to the second light source 703. The scanning head 701, the first light source 702, and the second light source 703 are respectively fixed to the worktable 2 by brackets. When the reagent card is sent to the bottom of the worktable 2 through the reading port 11, the first light source 702 and the second light source 703 are located on the front and rear sides of the reagent card. The two interact with each other, which can effectively eliminate the influence of background stray light on the reagent card and improve the accuracy of blood type reading. In this embodiment, the first light source 702 is set vertically downwards from the worktable 2, providing a larger illumination range. The second light source 703 is set close to the worktable 2 to avoid obstructing the reagent card and facilitate scanning by the scanning head 701.

[0030] Specifically, the sample loading module 3 includes an X-guide rail 301, a Y-guide rail 302, a Z-axis suction head assembly, and a Z-axis gripper assembly. One end of the Y-guide rail 302 is slidably connected to the X-guide rail 301. The Z-axis suction head assembly and the Z-axis gripper assembly are slidably disposed on opposite sides of the Y-guide rail 302. The Z-axis suction head assembly includes a disposable suction head mover 307 and a suction head drive device 303 for driving the disposable suction head mover 307 to move up and down. A disposable suction head 305 is mounted on the lower end of the disposable suction head mover 307. The Z-axis gripper assembly includes a gripper base 308 and a gripper drive device 304 for driving the gripper base 308 to move up and down. Two relatively movable grippers 306 are mounted on the bottom of the gripper base 308. The Z-axis suction head assembly and the Z-axis gripper assembly can move left and right and forward and backward above the worktable 2 via the X-guide rail 301 and the Y-guide rail 302, respectively. The disposable pipette tip mover 307 is equipped with a needle removal device, which allows the disposable pipette tip 305 to be replaced when changing to a different reagent after one reagent addition. In this embodiment, the pipette tip carrier 4 has several independent receiving slots, allowing the used disposable pipette tips 305 to be returned to their original receiving slots. The gripper 306 can grasp the reagent card for puncture, heating, and interpretation via the gripper base 308, and moves up and down under the action of the gripper drive device 304. The gripper drive device 304, the pipette tip drive device 303, and the gripper base 308 are all conventional settings and will not be described in detail.

[0031] Specifically, the front of the shaking and refrigeration unit 13 is equipped with a scanning dock 20, which is used to scan reagent cards and read their barcodes. A refrigeration module 21 is connected to the bottom of the shaking and refrigeration unit 13 and is fixed to the back of the workbench 2. The temperature of the shaking and refrigeration unit 13 is stably controlled within the required experimental range by the bottom refrigeration module 21. The refrigeration module 21 can be a semiconductor cooling chip.

[0032] The heating module 9 includes a heating plate 901. The surface of the heating plate 901 has a slot 902 adapted to the reagent card. A heating element is located inside the heating plate 901. A temperature sensor 903 is connected to the heating plate 901 for real-time temperature monitoring. In this embodiment, the heating module 9 is an inverted box fixed on the workbench 2, with the top plate serving as the heating plate 901. The heating element can be a ceramic heating element or a resistance wire.

[0033] The centrifuge module 6 includes a housing 602 and a centrifuge disposed inside the housing 602. The top of the housing 602, near the heating module 9, has a placement port 601 for inserting reagent cards. A fixing bracket 603 is connected to the bottom of the housing 602 and is fixed to the base plate of the cabinet 1. In this embodiment, the housing and the workbench 2 are snapped together, with only the placement port 601 located above the workbench 2. The main body of the centrifuge module 6 is located below the workbench 2, optimizing the space utilization of the workbench 2. Furthermore, the double fixation of the workbench 2 to the base plate of the cabinet 1 ensures structural stability and reduces vibration interference to other modules.

[0034] Specifically, the rear side of the diluent carrier 14 is provided with a deep well plate 18 for use with it. The deep well plate 18 has multiple holes, which is suitable for high-frequency and multi-sample detection and optimizes the sample dilution process.

[0035] The blood typing analyzer in this embodiment mainly performs the following experimental process: The Z-direction pipette assembly of the sample loading module 3 loads disposable pipette tips 305 from the pipette tip carrier 4, and draws experimental liquids from the reagent carrier 5 and the shaking and refrigeration unit 13 respectively, and moves them to the diluent carrier 14 for reagent mixing; The Z-direction gripper assembly of the sample loading module 3 grabs the reagent card in the gel carrier 8 and sends it to the puncture module 10 for puncture, and then puts it back into the gel carrier 8. The disposable pipette tip 305 draws the mixed reagents and moves them to the gel carrier 8 for sample loading at the well position of the reagent card. Then, the sampled reagent card is moved to the card slot 902 of the heating module 9 for heating and incubation. After incubation, the reagent card is taken out from the heating plate 901 and sent to the centrifuge for centrifugation through the placement port 601 at the top of the centrifugation module 6 housing 602. The centrifuged reagent card is transferred to the reading port 11 and moved down to the reading module 7. The first light source 702 and the second light source 703 illuminate the reagent card, and the scanning head 701 acquires the image.

[0036] The specific embodiments of this utility model have been described in detail above with reference to the figures, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
