It mainly includes a new cup loading module, a sample adding module, an incubation module, a cleaning module, a measurement module and a software control module. During the entire operation, the new cup loading module first provides a reaction cup, and the sample adding module is used to add the body fluid sample to be analyzed into the reaction cup, and then the reaction reagent with magnetic beads adsorbed with antigens or antibodies is added to the reaction cup. After the sample and reagent are incubated in the incubation module, they need to enter the cleaning module for cleaning to remove the unreacted body fluid sample and reagent, leaving only the complex connected to the magnetic beads after the reaction. Finally, the complex is placed in the measurement module for measurement to obtain the measurement result.

[0003] The various components of the existing immunoanalyzer are relatively independent, and the reaction cups are transported between the modules by a robot.

[0013] In one embodiment, the hatching slots correspond to the setting positions of the heating element, the heating element is arranged in an L-shaped structure on the outer side of the transfer plate, and each of the hatching slots is arranged in an L-shape on the mounting seat.

[0014] In one embodiment, the mounting seat has a first end surface; the transfer plate and the hatching tank are both arranged on the first end surface.

[0015] In one embodiment, the slide groove is in the shape of a long strip extending from the cup filling end to the cup discharge end, and the angle between the extension direction of the slide groove and the first end face is an acute angle.

[0016] In one of the embodiments, a heat collecting groove is provided on the mounting seat; the heating element is installed in the heat collecting groove, and the air guide hole is connected to the heat collecting groove.

The reaction cup can automatically slide down the slide groove at a suitable speed, and the reaction cup can also be manually loaded into the slide, thereby reducing the production cost of the analyzer.

[0024] By setting the heating element in an L shape and arranging the incubation tank into an L shape corresponding to the heating element, it is effectively ensured that when the reaction cup is embedded in the cup mouth and rotates with the transfer plate, the movement path of the reaction cup first passes through the part of the mounting seat where the heating element is provided, to ensure that the reaction cup is fully heated. When the reaction cup is rotated to the outer edge of the mounting seat, the new reaction cup that has completed the residual heat is avoided from interfering with the reaction cup in the incubation tank during the clamping and transportation process, which effectively shortens the distance that the robot lifts the reaction cup, thereby reducing the production cost of the analyzer.

[0040] See also Figures 1 to 4, is a loading mechanism 100 according to an embodiment of the present invention, comprising a slideway 10 and a rotating disk 20. A slideway 10 is provided with a slide groove 15, one end of the slideway 10 is a cup loading end 16, and the other end of the slideway 10 is a cup discharging end 17, the cup loading end 16 is used to load a new reaction cup 90 into the slideway 10, and the cup discharging end 17 is used to send a new reaction cup 90 into the rotating disk 20 for loading a new cup; the slide groove 15 runs through the cup loading end 16 and the cup discharging end 17, and the reaction cup 90 slides in the slide groove 15, so that the slideway 10 can load the new reaction cup 90. The rotating disk 20 includes a mounting seat 21 and a transfer plate 22, the mounting seat 21 is connected to the cup outlet end 17, and the transfer plate 22 is rotatably connected to the mounting seat 21; a cup mouth 221 is provided on the transfer plate 22, and the slide 15 is communicated with the cup mouth 221 to transport the reaction cup 90 in the slide 15 to the cup mouth 221 of the transfer plate 22, and the transfer plate 22 receives the new reaction cup 90 transported by the slide 10, and transfers the new reaction cup 90 to the workstation to be clamped by the robot by rotating, so as to ensure that the subsequent robot transports the reaction cup 90 to the sample addition module and adds samples and reagents into the reaction cup 90. Among them, the rotating disk 20 also includes a heating element 23, and the heating element 23 is connected to the mounting seat 21; an incubation groove 211 and an air guide hole 212 are provided on the mounting seat 21, and the air guide hole 212 is connected to the incubation groove 211, and at least a part of the air guide hole 212 is covered by the heating element 23. By providing the air guide hole 212 connected to the incubation groove 211 on the mounting seat 21, it is ensured that when the reaction cup 90 is inserted into the incubation groove 211, the air in the incubation groove 211 can be discharged through the air guide hole 212, thereby ensuring the fit between the reaction cup 90 and the inner wall of the incubation groove 211, avoiding the reaction cup 90 from floating in the incubation groove 211, thereby improving the heating efficiency of the reaction cup 90, realizing the incubation operation of the reaction cup 90 placed in the incubation groove 211, and then realizing the integration of the incubation module and the new cup loading module, and realizing the miniaturization requirement of the immunoassay analyzer.

[0041] Furthermore, the slideway 10 includes a side plate 11 and a cushion block 12. The side plates 11 are relatively arranged on both sides of the slideway 15, and the side plates 11 are arranged in parallel in a straight plate shape. The side plates 11 are used to support the reaction cup 90 and guide the movement of the reaction cup 90, thereby ensuring that the reaction cup 90 slides in the slideway 15. It can be understood that the reaction cup 90 is provided with a flange 95, and the flange 95 abuts against the top of the side plates 11 on both sides, thereby realizing the movement of the reaction cup 90 along the slideway 15.

[0042] Further, the pad 12 is arranged between the side plates 11 on both sides, and the pad 12 abuts against the side plates 11 on both sides to provide support for the side plates 11 on both sides, control the spacing between the side plates 11 to be balanced and unchanged, and improve the stability of the transport of the reaction cup 90. It can be understood that the shape of the pad 12 is a long strip extending along the direction of the slide 15, a cylindrical shape arranged at intervals along the direction of the slide 15, or a square shape arranged at intervals along the direction of the slide 15; the specific shape of the pad 12 is not limited here, and it is sufficient to ensure that the pad 12 can support the side plates 11 on both sides, thereby ensuring that the spacing between the two side plates 11 is equal everywhere. In this embodiment, the slide 10 also includes a filling block 13. The filling block 13 is arranged at the cup loading end 16 of the slide 10, and the slide 10 is sleeved on the outside of the side plates 11 on both sides. The filling block 13 is used to introduce the reaction cup 90 into the slide 15 to facilitate the manual completion of the task of loading the reaction cup 90.

[0043] Furthermore, the mounting seat 21 is roughly in a cubic shape, and an opening 214 is formed on the mounting seat 21. The opening 214 corresponds to the setting position of the transfer plate 22, and one end of the side plate 11 is correspondingly inserted into the opening 214, that is, the cup outlet end 17 of the slideway 10 is correspondingly inserted into the opening 214 of the mounting seat 21, so as to ensure that the reaction cup 90 in the slide groove 15 slides into the mounting seat 21 more stably to avoid the cup being stuck.

[0044] Furthermore, the transfer plate 22 is a circular block structure, and the transfer plate 22 is embedded in the mounting seat 21. The transfer plate 22 can rotate relative to the mounting seat 21, and the transfer plate 22 is arranged on one side of the opening 214 to receive the reaction tube transported through the opening 214. The transfer plate 22 is provided with a cup mouth 221, and the cup mouth 221 is arranged in a groove shape on the outer wall of the transfer plate 22. The cup mouth 221 is arranged at intervals around the transfer plate 22, and the reaction cup 90 passing through the opening 214 will slide into the cup mouth 221 on the transfer plate 22. At this time, the flange 95 on the outside of the reaction cup 90 will abut against the transfer plate 22, and the reaction cup 90 will rotate with the transfer plate 22 until it moves to the grabbing station of the manipulator, and the manipulator can extract the reaction cup 90 from the transfer plate 22.

[0045] Further, the mounting seat 21 has a first end surface 215. The transfer plate 22 and the hatching tank 211 are both arranged on the first end surface 215; in the present embodiment, the first end surface 215 is the top plane of the mounting seat 21. The chute 15 is in the shape of a long strip extending from the cup loading end 16 to the cup discharging end 17, and the angle between the extending direction of the chute 15 and the first end surface 215 is an acute angle. Optimally, the angle between the extending direction of the chute 15 and the first end surface 215 is 20 to 35 degrees, that is, the inclination angle of the chute 15 is 20 to 35 degrees. After a large number of experimental tests, the inclination angle is set at 20 to 35 degrees, which can effectively avoid the excessive application of the gravity component of the reaction cup 90 in the sliding direction along the chute 15 due to the excessive inclination angle, or the excessive application of the gravity component of the reaction cup 90 in the sliding direction perpendicular to the chute 15 due to the excessive inclination angle, thereby effectively avoiding the situation where the slide 10 is stuck. Furthermore, the angle between the slide 15 and the first end face 215 is α, and the friction coefficient between the slide 10 and the reaction cup 90 is f; wherein f<tanα. Similarly, through a large number of experiments, it is found that when the friction coefficient f between the slide 10 and the reaction cup 90 satisfies less than tanα, the reaction cup 90 can be effectively prevented from getting stuck. Then, the inclination angle of the slide 15 can be selected first, and the tanα value can be calculated after the α value is determined, and this can be used as the upper limit of f. The material of the slide 10 can be selected according to this upper limit. The above formula can effectively balance the stability of the slide 10 in conveying the reaction cup 90 and the economic efficiency of the material selection, production and processing method of the slide 10.

[0046] Furthermore, the incubation groove 211 is in the shape of an elongated strip and extends from the first end surface 215 toward the inside of the mounting seat 21 . The incubation groove 211 extends in a direction perpendicular to the first end surface 215 and is used for inserting the reaction cup 90 to be incubated.

[0047] Furthermore, the air guide hole 212 includes a connecting portion 2121 and an air guide portion 2122 . The connecting portion 2121 is in the shape of an elongated strip and is arranged at one end of the incubation tank 211 close to the heating element 23. The connecting portion 2121 has the same extension direction as the incubation tank 211. One end of the connecting portion 2121 is connected to the incubation tank 211, and the other end of the connecting portion 2121 is connected to the air guide portion 2122. The air guide portion 2122 is arranged on one side of the heating element 23. One end of the air guide portion 2122 passes through the side wall of the mounting seat 21 to be connected to the outside of the mounting seat 21, and the other end of the air guide portion 2122 extends into the mounting seat 21 to ensure that when the reaction cup 90 is inserted into the incubation tank 211, the air inside the incubation tank 211 can flow to the air guide portion 2122 through the connecting portion 2121 and be discharged to the outside through the air guide portion 2122, thereby ensuring the fit between the reaction cup 90 and the incubation tank 211, improving the heat conduction efficiency, and thus ensuring the incubation effect. In the present embodiment, the number of the hatching slots 211 is multiple, and the hatching slots 211 are arranged on the outer side of the transfer plate 22, and the hatching slots 211 are arranged at intervals along the first end surface 215; the number of the connecting parts 2121 and the hatching slots 211 is the same, and the connecting parts 2121 and the hatching slots 211 are arranged one by one; the air guiding part 2122 is arranged at one end of the connecting part 2121 away from the hatching slots 211, and the air guiding part 2122 is connected to each connecting part 2121 in sequence. Since the gas in the air guiding hole 212 is in contact with the heating element 23, it also has a certain thermal conductivity performance. The air guiding part 2122 is connected with each connecting part 2121, and the heat transfer in each hatching slot 211 is synchronized to ensure that the hatching environment in each hatching slot 211 is consistent, thereby improving the accuracy of data comparison and detection.

[0048] Further, the heating element 23 is in the shape of a straight plate, and the heating element 23 is arranged on a side of the mounting seat 21 away from the first end face 215. The heating element 23 is covered with an air guide portion 2122. The heating element 23 is used to generate heat, and the heat generated by the heating element 23 is directly transmitted to the incubation tank 211 through the mounting seat 21. The incubation tank 211 corresponds to the setting position of the heating element 23, that is, the incubation tank 211 is arranged in the area of ​​the positive projection of the heating element 23 to the first end face 215. It can be understood that the heating element 23 is one of an electric heating wire, an electric heating film, a graphite sheet or a semiconductor heating sheet, etc. The specific heating type of the heating element 23 is not limited here, and it is ensured that the heating element 23 can generate heat during operation so that an incubation environment is formed in the incubation tank 211. In this embodiment, the heating element 23 is arranged in an L-shaped structure, and the heating element 23 is arranged on the outer side of the transfer plate 22. The incubation groove 211 is arranged in an L-shape on the mounting seat 21. After the reaction cup 90 slides into the cup mouth 221, it rotates toward the heating element 23 to ensure that the new reaction cup 90 is preheated. The reaction cup 90 is fully preheated after rotating through the two sides where the heating element 23 is set, and enters the side where the heating element 23 is not set, that is, the gripping position of the manipulator for the reaction cup 90 is set at the outer edge of the mounting seat 21, thereby preventing the new reaction cup 90 from interfering with the reaction cup 90 in the incubation groove 211, effectively shortening the lifting distance of the reaction cup 90 by the manipulator, and thereby reducing the production cost of the analyzer.

[0049] Furthermore, a heat collecting groove 213 is provided on the mounting seat 21. The heat collecting groove 213 is arranged in a groove shape on the side of the mounting seat 21 away from the first end face 215, and the heating element 23 is installed in the heat collecting groove 213. The air guide hole 212 is connected to the heat collecting groove 213. The heat collecting groove 213 is used to reduce the loss of heat generated by the heating element 23, thereby improving the thermal efficiency. In this embodiment, a heat preservation member 24 and a fixing plate 25 are provided on the side of the heating element 23 away from the mounting seat 21. The heat preservation member 24 is in a straight plate shape, and the heat preservation member 24 abuts against the heating element 23. The heat preservation member 24 is arranged in the heat collecting groove 213, and the fixing plate 25 is arranged on the side of the heat preservation member 24 away from the heating element 23. The fixing plate 25 is connected to the mounting seat 21 to seal the heating element 23 and the heat preservation member 24 in the heat collecting groove 213, further reducing the loss of heat generated by the heating element 23, improving the thermal efficiency, and thereby improving the hatching effect. Specifically, the thermal insulation component 24 is thermal insulation cotton.

[0050] The working process of the present invention is as follows: when in use, the reaction cup 90 is manually loaded into the cup loading end 16 of the slideway 10, the reaction cup 90 slides in the slideway 15 toward the cup outlet end 17, the reaction cup 90 slides into the cup opening 221 of the transfer plate 22 through the opening 214 of the mounting seat 21, and the reaction cup 90 rotates to the position to be grasped together with the transfer plate 22; the robot grasps the reaction cup 90 to the sample adding module to add samples and reagents, and then the robot puts the reaction cup 90 into the incubation tank 211, and the heat generated by the heating element 23 enters the incubation tank 211 through the mounting seat 21 and the air guide hole 212, and the sample and reagent in the reaction cup 90 are incubated. In this way, the new cup loading module and the incubation module of the analyzer are combined into one whole.

[0051] In summary, the embodiment of the present invention provides a loading mechanism 100, which has the following beneficial effects:

[0052] By opening an incubation slot 211 on the mounting base 21 and connecting the heating element 23 to the mounting base 21, the new cup loading module and the incubation module are combined into a whole, thereby reducing the occupied space, realizing the miniaturization demand of the immunoassay analyzer, reducing the production cost of the analyzer, and being more conducive to the use needs of the mid- and low-end markets.

[0053] By integrating the incubation module and the new cup loading module into a whole, the heat generated by the heating element 23 during the incubation process can preheat the unused reaction cup 90 transported by the loading module, thereby increasing the temperature of the reaction cup 90 during the process of adding samples and reagents, thereby improving the accuracy of the analyzer's detection results.

[0054] By providing the air guide hole 212, the gas squeezed during the insertion of the reaction cup 90 into the incubation tank 211 is discharged from the mounting seat 21, so as to prevent the reaction cup 90 from being suspended in the incubation tank 211, thereby improving the fit between the reaction cup 90 and the incubation tank 211, thereby ensuring the heat conduction efficiency and the incubation effect of the reaction cup 90. The air guide part 2122 is used to synchronously connect the connecting parts 2121, so that the incubation environment in each incubation tank 211 changes synchronously, ensuring that the incubation temperature in each incubation tank 211 is balanced and uniform, and ensuring the accuracy of the comparison test result.

[0055] By setting the angle between the extension direction of the chute 15 and the first end face 215 to 20 to 35 degrees, it is ensured that the slideway 10 does not need to be provided with other additional driving components to transport the reaction cup 90, and the reaction cup 90 can automatically slide down in the chute 15 at a suitable speed, and the reaction cup 90 can also be manually loaded into the chute 10, thereby reducing the production cost of the analyzer. By controlling the inclination angle of the chute 15, it is prevented that the gravity component of the reaction cup 90 is excessively applied in the sliding direction along the chute 15, or the inclination angle is too small, resulting in the gravity component of the reaction cup 90 being excessively applied in the sliding direction perpendicular to the chute 15, thereby preventing the reaction cup 90 from getting stuck when entering the cup mouth 221 of the transfer plate 22.

[0056] By arranging the heating element 23 in an L shape and arranging the incubation tank 211 into an L shape corresponding to the heating element 23, it is effectively ensured that when the reaction cup 90 is embedded in the cup mouth 221 and rotates with the transfer plate 22, the movement path of the reaction cup 90 first passes through the part of the mounting seat 21 where the heating element 23 is provided, ensuring that the reaction cup 90 is fully heated. When the reaction cup 90 is rotated to the outer edge position of the mounting seat 21, the new reaction cup 90 that has completed the residual heat is avoided from interfering with the reaction cup 90 in the incubation tank 211 during the clamping and transportation process, which effectively shortens the distance that the robot lifts the reaction cup 90, thereby reducing the production cost of the analyzer.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
