[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figure 1 and Figure 2As shown, this embodiment provides a sample analyzer, which includes a scheduling disk 100, an incubation disk 200, a magnetic separation component 300 and a transfer component 400, wherein a first scheduling station 110 is arranged on the scheduling disk 100; an incubation scheduling position 210 is arranged on the incubation disk 200, and the incubation disk 200 is coaxially arranged with the scheduling disk 100 and rotates relatively independently; the magnetic separation component 300 is arranged on the outer periphery of the scheduling disk 100, and the magnetic separation component 300 has a separation station 310; the output end of the transfer component 400 can swing around a rotating shaft, and the axis of the rotating shaft is parallel to the axis of the incubation disk 200, and the first scheduling station 110, the incubation scheduling position 210 and the separation station 310 are all located on the swing path 410 of the output end of the transfer component 400.

[0041] The sample analyzer reduces the footprint of the scheduling disk 100 and the incubation disk 200 by coaxially arranging the scheduling disk 100 and the incubation disk 200, resulting in a smaller footprint of the entire sample analyzer, which is conducive to the miniaturization and compactness of the device. In addition, the magnetic separation component 300 is arranged on the periphery of the scheduling disk 100, and in the process of the output end of the transfer component 400 swinging around the rotation axis, it can pass through the first scheduling station 110, the incubation scheduling station 210 and the separation station 310, so that the reaction cup is transferred from the incubation disk 200 to the magnetic separation component 300, and the reaction cup is transferred from the magnetic separation component 300 to the scheduling disk 100. The operation can be completed by only one transfer component 400, reducing the number of transfer components 400, which is conducive to reducing the cost of the sample analyzer and reducing the footprint.

[0042] In some embodiments, the scheduling disk 100 is annular, the incubation disk 200 is disc-shaped, and the incubation disk 200 is located inside the scheduling disk 100. The above arrangement makes the incubation disk 200 surrounded by the scheduling disk 100, and the incubation disk 200 is located in the center, which helps to reduce the heat dissipation in the incubation disk 200, is conducive to the accumulation of heat, and under the premise of constant temperature, the amount of heat required to be provided is reduced, thereby achieving energy conservation and emission reduction. Further, a thermal insulation layer can be set around the outer periphery of the incubation disk 200, and the thermal insulation layer is located between the incubation disk 200 and the scheduling disk 100. Specifically, the thermal insulation layer can be a vacuum layer or a foam layer.

[0043] In this embodiment, the magnetic separation component 300 is located at the periphery of the scheduling disk 100, and the first scheduling station 110 is located between the incubation scheduling station 210 and the separation station 310. With the above position arrangement, after the incubation is completed, the reaction cup is transferred from the incubation scheduling station 210 to the separation station 310 by the transfer component 400, the reactants of the sample and the reagent in the reaction cup are cleaned, and then the test is performed, and after the test is completed, the reaction cup is transferred to the first scheduling station 110, and then the reaction cup is transferred to the next station under the rotation of the scheduling disk 100.

[0044] Regarding the test process, it is to collect and analyze the optical signal data of the reactants. In this embodiment, the reading component 500 of the sample analyzer has a pre-test station 510 at one end and a test station 520 at the other end, and the pre-test station 510 is located on the swing path 410 of the output end of the transfer component 400. The above-mentioned setting enables the reaction cup to be transferred between the first scheduling station 110, the incubation scheduling station 210, the separation station 310 and the pre-test station 510 under the drive of the transfer component 400, thereby greatly reducing the number of transfer components 400, reducing costs, and reducing the floor space; at the same time, the setting of the same transfer component 400 makes the scheduling disk 100, the magnetic separation component 300, and the pre-test station 510 of the reading component 500 surround the outer periphery of the axis of the rotating shaft of the transfer component 400, which is compact in structure and further reduces the floor space. It should be noted that the transfer of the reaction cup between the pre-test station 510 and the test station 520 and the method of testing the reactants at the test station 520 by the reading component 500 are well known to those skilled in the art and will not be described in detail here.

[0045] The pre-test station 510 is located between the first scheduling station 110 and the separation station 310. This arrangement allows the reactants in the reaction cup to be transferred to the pre-test station 510 at the shortest distance after cleaning, thereby improving the detection efficiency; at the same time, the time between the reactants after cleaning and before detection is reduced, thereby reducing the impact on the test results and improving the test accuracy.

[0046] When the test is completed, the reaction cup needs to be discarded to achieve the subsequent recycling of the reaction cup. Specifically, in this embodiment, the sample analyzer includes a waste cup member 600, which is arranged on the swing path 410 at the output end of the transfer component 400 and is used to receive the reaction cup that has completed the test. In other words, after the reactant in the reaction cup is tested, the reaction cup is thrown into the waste cup member 600.

[0047] Regarding the position of the waste cup member 600, in some embodiments, the waste cup member 600 is located between the first scheduling station 110 and the pre-test station 510. This position layout allows the reaction cup to be transferred from the test station 520 to the pre-test station 510 by the reading component 500 after the test is completed, and then the reaction cup is transferred to the waste cup member 600 by the transfer component 400.

[0048] Furthermore, in order to avoid residual reactants in the reaction cup collected by the waste cup part 600, in some embodiments, the sample analyzer is also provided with a waste liquid suction part 610 and a waste liquid barrel. The waste liquid barrel is located at the waste liquid position 620, and the waste liquid position 620 is located outside the scheduling disk 100. The scheduling disk 100 is provided with a second scheduling station 120. The output end of the waste liquid suction part 610 can move between the second scheduling station 120 and the waste liquid barrel, and can absorb the reactants in the reaction cup on the second scheduling station 120 and discharge them into the waste liquid barrel. This position layout allows, after the test is completed, the reaction cup is first transferred from the test station 520 to the pre-test station 510 by the reading component 500, and then the reaction cup is moved to the first scheduling station 110 by the transfer component 400. The scheduling disk 100 rotates to move the reaction cup to the second scheduling station 120, and the reactants in the reaction cup are sucked by the waste liquid suction piece 610 and discharged into the waste liquid barrel of the waste liquid position 620. The scheduling disk 100 rotates again to move the reaction cup to the first scheduling station 110, and finally the reaction cup is transferred to the waste cup piece 600 by the transfer component 400.

[0049] To improve the test efficiency, in some embodiments, the incubation tray 200 has a plurality of incubation positions, which enclose at least two working rings, and there are at least two incubation scheduling positions 210, which are used to place reaction cups. During the rotation of the incubation tray 200, the incubation positions in each working ring can pass through the corresponding incubation scheduling position 210. The setting of the plurality of incubation positions allows the incubation tray 200 to hold a plurality of reaction cups at the same time, so as to complete the incubation at the same time, thereby improving the test efficiency.

[0050] The incubation positions are surrounded by three working rings, and there are three incubation scheduling positions 210. It is worth noting that the three incubation scheduling positions 210 are all located on the swing path 410 of the transfer assembly 400, and each time the scheduling disk 100 rotates, three incubation positions move to the three incubation scheduling positions 210 accordingly.

[0051] The swing angle of the output end of the transfer assembly 400 is less than or equal to 180 degrees. The above angle limit, to a certain extent, limits the positional relationship between the magnetic separation assembly 300 and the scheduling disk 100, making the two as compact as possible and reducing the footprint of the sample analyzer.

[0052] Regarding the structure of the transfer assembly 400, in this embodiment, the transfer assembly 400 includes a swing arm, a lifting arm and a gripper. One end of the swing arm is rotatably disposed on a rotating shaft, the lifting arm is slidably disposed at the other end of the swing arm along a vertical direction, and the gripper is disposed at the lower end of the lifting arm, and the gripper is used to grab the reaction cup.

[0053] After incubation, after the reactant is cleaned, there may be a situation of secondary incubation. In the present embodiment, the sample analyzer includes a reagent tray 700, which is used to hold the reagent used for the reaction, and the reagent tray 700 is arranged at the periphery of the scheduling tray 100, and the reading component 500 is located between the reagent tray 700 and the magnetic separation component 300. The above-mentioned setting makes it possible to refill the reagent after the reactant in the reaction cup is cleaned, and to incubate the processes again to meet different process requirements. At the same time, by means of the position setting of the above-mentioned reagent tray 700, the structure of the reading component 500, the reagent tray 700 and the magnetic separation component 300 is compact, reducing the floor space; finally, the above-mentioned positional relationship makes the distance between the reagent tray 700 and the scheduling tray 100 as close as possible, shortening the time of filling the reagent and improving the efficiency of filling the reagent.

[0054] For ease of operation, in some embodiments, the reagent tray 700 is located at the front of the rack 1000 of the sample analyzer. Wherein, the scheduling disk 100 is located at the rear side of the reagent tray 700. The magnetic separation assembly 300 is located at the rear side of the reagent tray 700. The above position is limited so that the operator can place the reagent in the reagent tray 700 as quickly as possible, which improves the convenience and efficiency of operation. The reagent needle 710 can swing around its own axis so that the output end of the reagent needle 710 can move around the reagent path 711, and the reagent path 711 and the reagent tray 700 intersect at the reagent position, and the reagent container for holding the reagent is placed at the reagent position. The reagent needle 710 transfers the reagent at the reagent position in the reagent tray 700 to the reaction cup of the third scheduling station 130. The output end of the reagent needle 710 is provided with a suction piece for sucking the reagent in the reagent container and discharging it into the reaction cup.

[0055] It is worth noting that the rack 1000 also has a rear portion opposite to the front portion, and a conveying track is provided at the rear portion of the rack 1000 for conveying samples, and the operator operates at the front portion of the rack 1000 to complete operations such as reagent replenishment. The above arrangement can keep samples with infectious aerosols away from the front portion of the rack 1000 and the operator as far as possible, thereby improving the safety of the operator.

[0056] The sample needle 840 can swing around its own axis so that the output end of the sample needle 840 moves in the sample path 841. The transmission track includes a first track 810 and a second track 820. The first track 810 and the second track 820 intersect with the sample path 841 to form a first loading position 811 and a second loading position 821. The output end of the sample needle 840 is provided with a suction piece for sucking the reagent in the sample container and discharging it into the reaction cup.

[0057] In some embodiments, the transmission speed of the first track 810 is greater than the transmission speed of the second track 820, and the first track 810 is closer to the sample needle 840, and the first track 810 is used to transmit the expedited sample. The sample needle 840 is used to extract the samples from the first loading position 811 and the second loading position 821 and fill them into the reaction cup at the fourth scheduling position 140 on the scheduling plate 100.

[0058] The sample is placed in a sample container, and the sample analyzer is further provided with a recovery track 830, and the sample container from which the sample is extracted is moved by the manipulator to the recovery track 830. In some embodiments, the recovery track 830 is connected to the first track 810 and to the second track 820, and after the sample in the sample container is extracted, the sample container is pushed by the pushing mechanism and moved to the recovery track 830.

[0059] It is worth mentioning that the scheduling tray 100 , incubation tray 200 , magnetic separation assembly 300 , transfer assembly 400 , reading assembly 500 , waste cup 600 , reagent tray 700 and transmission track and other components are all arranged on the frame 1000 .

[0060] In some embodiments, the reaction cup is transferred from the cup dispensing member 421 to the scheduling plate 100 by the mechanical swing arm 420. The rotation process of the scheduling plate 100 enables the reaction cup to move to each scheduling station.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
