Due to its characteristics such as high sensitivity, specificity, and wide linear range, it is being increasingly widely used. With the increase in the number of test specimens, clinical laboratories have higher and higher requirements for the volume and test throughput (throughput per unit area) of the chemiluminescence immunoassay system.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present invention in detail with reference to the drawings and in combination with the embodiments.

[0027] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0028] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are generally in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0029] In order to solve the problems of low test efficiency, large occupied area and low test accuracy existing in the sample analyzer device of the prior art, the present embodiment provides a sample analyzer device.

[0030] As Figure 1 shown, the sample analyzer device includes a gripper unit, a scheduling and photometry unit 20, a reaction cup feeding unit 30, a sampling plate 40, an incubation unit 50, a cleaning unit 60, a reagent unit 70 and a sample unit 80. The gripper unit includes an independently arranged first linear gripper 111 and a second linear gripper 121. A part of the scheduling and photometry unit 20 is located on the movement track of the first linear gripper 111, and another part is located on the movement track of the second linear gripper 121. The reaction cup feeding unit 30 and the sampling plate 40 are arranged on the movement track of the first linear gripper 111, the incubation unit 50 and the cleaning unit 60 are arranged on the movement track of the second linear gripper 121, and the reagent unit 70 and the sample unit 80 are located on the outer peripheral side of the sampling plate 40.

[0031] Among them, the movement trajectories of the first linear gripper 111 and the second linear gripper 121 are perpendicular to each other in the horizontal direction.

[0032] Specifically, the sample analyzer device adopted in the present application uses the mutually independent first linear gripper 111 and the second linear gripper 121 to cooperate to transfer reaction cups between the reaction cup loading unit 30, the sample adding tray 40, the incubation unit 50, the photometric unit and the cleaning unit 60 to achieve sample analysis. The first linear gripper 111 and the second linear gripper 121 are respectively adapted to different structures, and the completely independent setting between the two is beneficial to improving the overall operation convenience, solving the problem of the cooperation of multiple units and components. At the same time, the design of the cooperation of the double linear grippers and the incubation block solves the problems that in the prior art, an additional transfer mechanism needs to be set and the structures of the gripper and the incubation tray are complex, resulting in the problems of large overall occupied volume and high cost in the sample analyzer device of the prior art. The structure and layout of the sample analyzer device of the present application are more compact, the overall size of the instrument is smaller, and the test throughput and test speed per unit floor area of the instrument are improved.

[0033] Among them, the first linear gripper 111 is used to transfer the reaction cups provided by the reaction cup loading unit 30 between the sample adding tray 40 and the scheduling photometric unit 20; the second linear gripper 121 transfers the reaction cups between the scheduling photometric unit 20, the incubation unit 50 and the cleaning unit 60.

[0034] Furthermore, the sample adding tray 40, the reaction cup loading unit 30, and the scheduling photometric unit 20 are sequentially arranged along the movement trajectory of the first linear gripper 111, and the scheduling photometric unit 20, the incubation unit 50, and the cleaning unit 60 are sequentially arranged along the movement trajectory of the second linear gripper 121. Such a setting effectively optimizes the movement route of the linear gripper, shortens the movement stroke of the linear gripper, thereby improving the sample detection efficiency. At the same time, the sample adding tray 40, the reaction cup loading unit 30, and the scheduling photometric unit 20 sequentially arranged along the movement trajectory of the first linear gripper 111 are convenient to be adapted to the first linear gripper 111, and there is no interference between the structures, thereby improving the overall operation stability; similarly, the scheduling photometric unit 20, the incubation unit 50, and the cleaning unit 60 sequentially arranged along the movement trajectory of the first linear gripper 111 are convenient to be adapted to the second linear gripper 121, and there is no interference between the structures, thereby improving the overall operation stability.

[0035] Further, at least a part of the sample adding tray 40, the reaction cup feeding unit 30, the scheduling and photometry unit 20, the scheduling and photometry unit 20, the incubation unit 50, and the cleaning unit 60 are located below the gripper unit. Among them, at least a part of the sample adding tray 40, at least a part of the reaction cup feeding unit 30, and at least a part of the scheduling and photometry unit 20 are located below the first linear gripper 111, and at least a part of the scheduling and photometry unit 20, at least a part of the incubation unit 50, and at least a part of the cleaning unit 60 are located below the second linear gripper 121.

[0036] The first linear gripper 111 and the second linear gripper 121 of the present application move along a linear movement trajectory, and at the same time, the first linear gripper 111 and the second linear gripper 121 can move in a direction perpendicular to the movement trajectory, that is, move along the height direction of the reaction cup, so as to grasp or place the reaction cup.

[0037] In this embodiment, the gripper unit includes a first gripper structure 110 and a second gripper structure 120 arranged at intervals. The first gripper structure 110 has a first linear gripper 111, and the second gripper structure 120 has a second linear gripper 121. The scheduling and photometry unit 20 is arranged between the first gripper structure 110 and the second gripper structure 120. The first gripper structure 110, the scheduling and photometry unit 20, and the second gripper structure 120 form an included angle area, and the reaction cup feeding unit 30, the incubation unit 50, and the cleaning unit 60 are located inside the included angle area. By arranging the reaction cup feeding unit 30, the incubation unit 50, and the cleaning unit 60 inside the included angle area, it is beneficial to realize the compactness of the overall layout of multiple structures, facilitate the rational use of space, make the overall size of the instrument smaller, and improve the test throughput and test speed per unit floor area of the instrument.

[0038] Further, the first gripper structure 110 includes a first guide rail 112 extending linearly. The first linear gripper 111 is arranged on the first guide rail 112, and the first linear gripper 111 can reciprocate along the first guide rail 112. Among them, the first linear gripper 111 is slidably arranged on the first guide rail 112. The first gripper structure 110 further includes a first driving member for driving the first linear gripper 111 to slide, and the first driving member is arranged on the first guide rail 112. The linearly extending first guide rail 112 provides limit guidance for the movement of the first linear gripper 111 and provides installation for the first linear gripper 111, facilitating the stable reciprocating movement of the first linear gripper 111.

[0039] Further, the second gripper structure 120 includes a second guide rail 122 extending linearly. The second linear gripper 121 is disposed on the second guide rail 122, and the second linear gripper 121 can reciprocate along the second guide rail 122. The second linear gripper 121 is slidably disposed on the second guide rail 122. The second gripper structure 120 further includes a second driving member for driving the second linear gripper 121 to slide, and the second driving member is disposed on the second guide rail 122. The linearly extending second guide rail 122 provides limit guidance for the movement of the second linear gripper 121 and provides installation for the second linear gripper 121, facilitating the stable reciprocating movement of the second linear gripper 121.

[0040] In this embodiment, the first linear gripper 111 can transfer the reaction cups provided by the reaction cup loading unit 30 to the sample adding tray 40 or the scheduling and photometry unit 20. That is, the movement of the first linear gripper 111 can be to transfer the reaction cups provided by the reaction cup loading unit 30 to the sample adding tray 40, or to directly move the reaction cups to the scheduling and photometry unit 20. Specifically, the movement of the first linear gripper 111 can be adaptively set according to needs. The first linear gripper 111 can transfer the reaction cups between the sample adding tray 40 and the scheduling and photometry unit 20. The second linear gripper 121 can transfer the reaction cups between any two of the scheduling and photometry unit 20, the incubation unit 50, and the cleaning unit 60 to adaptively transfer the reaction cups according to needs.

[0041] As Figure 1 shown, the scheduling and photometry unit 20 includes a scheduling and photometry disc. The scheduling and photometry disc has a plurality of cup positions arranged at circumferential intervals. At least one cup position is located on the movement track of the first linear gripper 111, and another cup position is located on the movement track of the second linear gripper 121.

[0042] Specifically, the scheduling and photometry disc is rotatably disposed. The scheduling driving member provides driving force for the rotation of the scheduling and photometry disc. The retrieval driving member is drivingly connected to the scheduling and photometry disc. The scheduling and photometry disc rotates to transfer the reaction cup placed on one of the cup positions by the first linear gripper 111 to the movement track of the second linear gripper 121, facilitating the second linear gripper 121 to grasp the reaction cup; conversely, the reaction cup placed on the cup position by the second linear gripper 121 follows the rotation of the scheduling and photometry disc and is transferred to the movement track of the first linear gripper 111 to facilitate the first linear gripper 111 to grasp the reaction cup. Among them, the scheduling driving member can be a structure such as a cylinder or a motor.

[0043] By setting the scheduling photometric unit 20, the transfer of reaction cups between the first linear gripper 111 and the second linear gripper 121 is realized, achieving the function of reaction cup transfer and improving the moving speed of the reaction cups. Moreover, the scheduling photometric unit 20 also has the effect of photometric detection, facilitating the photometry of the reaction cups placed on the scheduling photometric unit 20 by the first linear gripper 111 or the photometry of the reaction cups placed on the scheduling photometric unit 20 by the second linear gripper 121.

[0044] Further, the scheduling photometric disc rotates to move the cup positions on the moving trajectory of the first linear gripper 111 to the moving trajectory of the second linear gripper 121.

[0045] Further, the scheduling photometric disc rotates to move the cup positions on the moving trajectory of the second linear gripper 121 to the moving trajectory of the first linear gripper 111.

[0046] In this embodiment, the cup positions on the scheduling photometric disc include a plurality of outer ring cup positions 210 arranged circumferentially and a plurality of inner ring cup positions 220 arranged circumferentially. The inner ring cup positions 220 are located inside the area formed by the outer ring cup positions 210. The outer ring cup positions 210 and the inner ring cup positions 220 correspond one by one and are linearly arranged, so that the outer ring cup positions 210 and the inner ring cup positions 220 on the same straight line are located on the moving trajectory of the first linear gripper 111 or the moving trajectory of the second linear gripper 121.

[0047] Among them, the outer ring cup positions 210 are used for the first linear gripper 111 to schedule reaction cups to the second linear gripper 121. At the same time, the outer ring cup positions 210 also have the function of photometry, that is, when photometry is required, the reaction cups after incubation and cleaning are moved to the outer ring cup positions 210 of the scheduling photometric unit 20 for photometry.

[0048] Among them, the inner ring cup positions 220 are used for the second linear gripper 121 to schedule reaction cups to the first linear gripper 111.

[0049] Through the settings of the inner ring cup positions 220 and the outer ring cup positions 210, the first linear gripper 111 schedules the reaction cups to the outer ring cup positions 210 of the scheduling photometric unit 20, and the second linear gripper moves the reaction cups at the outer ring cup positions 210 to the incubation unit 50. When secondary injection is actually required, the second linear gripper 121 schedules the reaction cups to the inner ring cup positions 220 of the scheduling photometric unit 20, and the first linear gripper 111 transfers the reaction cups at the inner ring cup positions 220 to the sample addition tray 40.

[0050] The scheduling photometric unit 20 of the present application has the structural settings of the inner ring cup positions 220 and the outer ring cup positions 210. During the process of scheduling reaction cups, different operations are independently set without interference, so as to realize the synchronous operation of photometry and secondary reagent injection, which is beneficial to improving work efficiency.

[0051] Among them, the inner circle cup position 220 and the outer circle cup position 210 are arranged linearly, so that the linearly arranged inner circle cup position 220 and the outer circle cup position 210 can be located on the motion trajectory of the first linear gripper 111 or the motion trajectory of the second linear gripper 121 at the same time, making it convenient for the first linear gripper 111 or the second linear gripper 121 to move the reaction cup to the inner circle cup position 220 and the outer circle cup position 210.

[0052] like Figure 1 As shown, in the horizontal direction, the incubation unit 50 is movably arranged along the vertical direction of the movement trajectory of the second linear gripper 121 , that is, in this embodiment, the incubation unit 50 is movably arranged along the direction of the movement trajectory of the first linear gripper 111 .

[0053] Specifically, the incubation unit 50 has multiple incubation positions for placing reaction cups, and the horizontal movement trajectory of the second linear gripper 121 is perpendicular to the moving direction of the incubation unit 50, so that the second linear gripper 121 can adapt to the multiple incubation positions arranged along the moving direction of the incubation unit 50 to grab or place the reaction cup.

[0054] Furthermore, the plurality of incubation sites may be arranged in an array or non-array manner.

[0055] Furthermore, the multiple incubation position incubation units 50 may adopt a square structure, or a circular structure or a structure of other shapes.

[0056] In a specific embodiment of the present application, the incubation unit 50 adopts a square structure.

[0057] Furthermore, the movement of the incubation unit 50 may be achieved through an incubation drive structure, which may be a cylinder, a motor, or the like.

[0058] In this embodiment, the incubation block unit provides a constant temperature reaction site for the sample and reagent reaction solution. The incubation unit 50 can not only realize the incubation of the reaction solution, but also realize the incubation of the substrate after the reaction cup is cleaned.

[0059] like Figure 1 As shown, the sample analyzer device also includes a first cup throwing position 90 and a second cup throwing position 1100. The first cup throwing position 90 is arranged below the gripper unit, and the first cup throwing position 90 is located on the motion trajectory of the first linear gripper 111. The second cup throwing position 1100 is arranged below the gripper unit, and the second cup throwing position 1100 is located on the motion trajectory of the second linear gripper 121.

[0060] Specifically, a first cup discarding position 90 set on the movement track of the first linear gripper 111 corresponds to the first linear gripper 111, so that when the photometry is completed or in other cases where reaction cups are not required, the first linear gripper 111 can place the used reaction cups at the first cup discarding position 90 for cup discarding; similarly, a second cup discarding position 1100 set on the movement track of the second linear gripper 121 corresponds to the second linear gripper 121, so that when the photometry is completed or in other cases where reaction cups are not required, the second linear gripper 121 can place the used reaction cups at the second cup discarding position 1100 for cup discarding.

[0061] By setting the first cup discarding position 90 and the second cup discarding position 1100, it is convenient for the first linear gripper 111 and the second linear gripper 121 to respectively perform cup discarding operations.

[0062] Furthermore, along the movement track of the first linear gripper 111, the first cup discarding position 90 is located between the reaction cup feeding unit 30 and the scheduling photometry unit 20. This is to facilitate the first linear gripper 111 to move the reaction cups after photometry completion to the first cup discarding position 90 and move the reaction cups provided by the reaction cup feeding unit 30 to the sample adding tray 40, reducing the movement path of the first linear gripper 111, increasing the movement speed, and improving work efficiency.

[0063] Furthermore, along the movement track of the second linear gripper 121, the second cup discarding position 1100 is located between the incubation unit 50 and the cleaning unit 60. This is to facilitate the second linear gripper 121 to move the incubated or cleaned reaction cups to the second cup discarding position 1100, reducing the movement path of the second linear gripper 121, increasing the movement speed, and improving work efficiency.

[0064] It should be noted that the sample analyzer device of the present application includes an operation frame, and the gripper unit, the scheduling photometry unit 20, the reaction cup feeding unit 30, the sample adding tray 40, the incubation unit 50, the cleaning unit 60, the reagent unit 70, and the sample unit 80 are all arranged on the operation frame. The first cup discarding position 90 and the second cup discarding position 1100 are also arranged on the operation frame, and the operation frame is used to provide installation for the components participating in sample analysis.

[0065] In this embodiment, the cleaning unit 60 uses magnetic cleaning means to clean the reaction cups.

[0066] As Figure 1 shown, the sample adding tray 40 is rotatably arranged. Along the rotation direction of the sample adding tray 40, the reagent unit 70 is located downstream of the sample unit 80. The sample adding tray 40 has a plurality of cup positions. When the sample adding tray 40 rotates, the cup positions for placing reaction cups are successively located on the movement track of the first linear gripper 111, below the sample unit 80, below the reagent unit 70, and on the movement track of the first linear gripper 111.

[0067] Among them, the sample analyzer device further includes a sample loading tray 40 driving structure, which is drivingly connected to the sample loading tray 40 and provides driving force for the rotation of the sample loading tray 40. The sample loading tray 40 driving structure can be structural components such as a motor or a cylinder.

[0068] Specifically, after the reaction cup is placed in a cup position, as the sample loading tray 40 rotates, this cup position moves below the sample unit 80. The sample unit 80 adds samples into the reaction cup through a sampling needle, and then this cup position moves below the reagent unit 70, and the reagent of the reagent unit 70 adds reagents into the reaction cup.

[0069] Furthermore, there are multiple cup positions on the sample loading tray 40, and the multiple cup positions are arranged at intervals along the circumferential direction of the sample loading tray 40.

[0070] Among them, the sample unit 80, the reaction cup feeding unit 30, the reagent unit 70, and the gripper unit cooperate with different cup positions on the sample loading tray 40 respectively. And in this application, the movement cycles of the sample unit 80, the reaction cup feeding unit 30, and the reagent unit 70 are the same as the time taken for the sample loading tray 40 to rotate the distance between two cup positions. That is to say, in this application, after the sample loading tray 40 rotates the interval length between every two cup positions, the reaction cup feeding unit 30 can provide a reaction cup to a cup position on the sample loading tray 40, and the sampling needle can provide a sample into an empty reaction cup on the sample loading tray 40 once and the reagent needle can add a reagent into the reaction cup after the sample is added once. And in this application, the sample loading tray 40 can be separately provided with one or more mixing working positions, and one or more mixers are arranged. The mixing working positions can be set downstream of the sampling cup position of the reagent needle, so that after the sample loading tray 40 completes sample addition, it rotates to the next position to mix the reaction solution. Furthermore, the mixing working positions can be set upstream of the gripper unit, and after the reaction solution is mixed, the sample loading tray 40 rotates to the trajectory of the gripper unit for the next operation.
