[0044] See also Figure 1 , Figure 2 as well as Figure 3 The present application provides a sample analyzer 10 for detecting and analyzing blood. The sample analyzer 10 includes a workbench 100, a cup grabbing mechanism 200, a turntable 300, a reaction cup storage device 410, an incubation device 500, a measuring device 600, a reagent storage device 420, a sample storage device 430, and a robotic arm. The cup grabbing mechanism 200, the turntable 300, the reaction cup storage device 410, the incubation device 500, the measuring device 600, the reagent storage device 420, the sample storage device 430, and the robotic arm are respectively arranged on the workbench 100. Among them:

[0045] The turntable 300 is rotatable relative to the workbench 100, and a cuvette storage device 410, an incubation device 500, and a measuring device 600 are disposed on one side of the turntable 300, and a reagent storage device 420 and a sample storage device 430 are disposed on the other side of the turntable 300. In one example, the turntable 300 is disposed at the center of the workbench 100, and the cuvette storage device 410, the incubation device 500, and the measuring device 600 are disposed sequentially from one side of the turntable 300 to the other side, and the reagent storage device 420 and the sample storage device 430 are also disposed sequentially from one side of the turntable 300 to the other side.

[0046] The reaction cup storage device 410 stores reaction cups, the sample storage device 430 stores samples via test tubes, and the reagent storage device 420 stores reagents via test tubes. The robotic arm is used to add the samples stored in the sample storage device 430 to the reaction cups, and the robotic arm is also used to add the reagents stored in the reagent storage device 420 to the reaction cups.

[0047] The cup grabbing mechanism 200 includes a first cup grabbing device 210 and a second cup grabbing device 220, and the first cup grabbing device 210 and the second cup grabbing device 220 are coaxially arranged. Coaxial here means that when the workbench 100 has an X-axis or a Y-axis, the first cup grabbing device 210 and the second cup grabbing device 220 share the X-axis or the Y-axis. The first cup grabbing device 210 is used to grab the reaction cup stored in the reaction cup storage device 410 to the turntable 300, and is also used to grab the reaction cup between the turntable 300 and the incubation device 500, and the incubation device 500 is used to incubate the reaction substance in the reaction cup. The second cup grabbing device 220 is used to grab the reaction cup between the incubation device 500 and the measuring device 600, and the measuring device 600 is used to measure the reaction substance in the reaction cup, and the second cup grabbing device 220 is also used to discard the reaction cup after the measurement is completed.

[0048] In the above sample analyzer 10, the first cup grabbing device 210 grabs the reaction cup from the reaction cup storage device 410 to the turntable 300, and the turntable 300 drives the reaction cup to rotate. During the rotation, the reaction cup experiences the addition of samples from the sample storage device 430 and reagents from the reagent storage device 420 by the robot arm. The reaction cup rotates one circle with the turntable 300 to achieve the addition of the reaction substance, and after one circle of rotation, the first cup grabbing device 210 grabs the reaction cup from the turntable 300 to the incubation device 500. After the incubation device 500 incubates the reaction substance in the reaction cup for a period of time, the second cup grabbing device 220 grabs the reaction cup from the incubation device 500 to the measuring device 600 for measurement. During the working process, since the first cup grabbing device 210 and the second cup grabbing device 220 are coaxially arranged, the grabbing process of the reaction cup is relatively simple and the grabbing structure is simple, and the transmission of the sensing cup is achieved by the rotation of the turntable 300 outside the moving range of the first cup grabbing device 210 and the second cup grabbing device 220, so that the process of adding samples and reagents to the reaction cup is relatively simple, thereby achieving efficient transmission of the reaction cup and easy planning of the movement path.

[0049] There are many ways to arrange the cuvette storage device 410, the measuring device 600, and the incubation device 500. Figure 2 In a preferred embodiment, the cuvette storage device 410, the incubation device 500, and the measuring device 600 are arranged along a first straight line so that the transfer path of the cuvette between the cuvette storage device 410, the incubation device 500, and the measuring device 600 is short, thereby reducing the transfer time. The cuvette storage device 410, the incubation device 500, and the measuring device 600 are located on the side of the turntable 300 away from the operator to avoid operator misoperation.

[0050] There are many ways to arrange the reagent storage device 420 and the sample storage device 430. For details, see Figure 2 , the reagent storage device 420 and the sample storage device 430 are arranged along the second straight line, and the first straight line is parallel to the second straight line, so that the arrangement of the reagent storage device 420 and the sample storage device 430 can make the positions of the components in the workbench 100 regular and the layout reasonable. In addition, the reagent storage device 420 and the sample storage device 430 are arranged along the second straight line on the side of the turntable 300 away from the operator, so that samples and reagents can be added to the workbench 100 from the outside, which is convenient for the operator to place the samples and reagents.

[0051] The structure of the turntable 300 has various forms. In a preferred embodiment, refer to Figure 2The turntable 300 has a plurality of stations 310, which are arranged around the center of the turntable 300 and are used to accommodate reaction cups, respectively. The plurality of stations 310 include a first station 330, a second station 330 and a third station 340. The first station 330 is located between the reaction cup storage device 410 and the incubation device 500, the second station 330 is close to the sample storage device 430, and the third station 340 is close to the reagent storage device 420. During operation, the first cup grabbing device 210 grabs the reaction cup from the reaction cup storage device 410 to the first station 330, the robot arm adds the sample of the sample storage device 430 to the reaction cup on the second station 330, and the robot arm adds the reagent of the reagent storage device 420 to the reaction cup on the third station 340, and the positions of other stations 310, the first station 330, the second station 330 and the third station 340 in the plurality of stations 310 are switched cyclically.

[0052] In one example, the turntable 300 can be driven by a synchronous belt rotation mechanism, and some of the multiple workstations 310 are common workstations 310, and some are spare workstations 310. Samples and reagents are added to the reaction cups at the common workstations 310 during one rotation of the turntable 300, while samples and reagents do not need to be added to the reaction cups at the spare workstations 310 during one rotation of the turntable 300.

[0053] To facilitate the grabbing of the reaction cup, see Figure 3 The first cup grabbing device 210 includes a first clamping jaw 211 and a first driving module 212. The first driving module 212 is used to drive the first clamping jaw 211 to move along a first direction. The first clamping jaw 211 is used to clamp a reaction cup, and the moving stroke A of the first clamping jaw 211 covers the reaction cup storage device 410, the incubation device 500 and the first workstation 330, so that the first cup grabbing device 210 can grab and transfer the reaction cup between the reaction cup storage device 410 and the first workstation 330, and between the first workstation 330 and the incubation device 500.

[0054] The second cup-grabbing device 220 includes a second clamp 221 and a second driving module 222. The second driving module 222 is used to drive the second clamp 221 to move along the first direction. The second clamp 221 is used to clamp the reaction cup, and the moving stroke B of the second clamp 221 covers the incubation device 500 and the measuring device 600, so that the second cup-grabbing device 220 can grasp and transfer the reaction cup between the incubation device 500 and the measuring device 600, and by limiting the second clamp 221 and the first clamp 211 to move along the first direction, the first cup-grabbing device 210 and the second cup-grabbing device 220 are coaxially arranged.

[0055] In one example, the first direction can be the X-axis direction or the Y-axis direction of the workbench 100, the first drive module 212 and the second drive module 222 can be belt transmission mechanisms, and the conveyor belt in the belt transmission mechanism extends along the first direction. Of course, the structural form of the first drive module 212 and the second drive module 222 is not limited to this, and can also be a gear rack structure, a cylinder structure, etc.

[0056] In one example, since the moving stroke A of the second jaw 221 and the moving stroke B of the first jaw 211 both cover the incubation device 500, in order to avoid interference, the moving stroke A of the second jaw 221 and the moving stroke B of the first jaw 211 can be staggered in time, or the setting positions of the second jaw 221 and the first jaw 211 can be staggered.

[0057] There are many structural forms of the mechanical arm. In a preferred embodiment, refer to Figure 1 , Figure 2 as well as Figure 3 The robot arm includes a loading arm 710, which is a double-section structure, so that the loading arm 710 can grab and add operations, and add reagents and samples to the reaction cup. The moving stroke of the loading arm 710 covers the sample storage device 430, the first area 421 of the reagent storage device 420 close to the sample storage device 430, and the second station 330, so that the loading arm 710 adds the sample of the sample storage device 430 to the reaction cup of the second station 330, and the loading arm 710 adds the reagent in the first area 421 of the reagent storage device 420 close to the sample storage device 430 to the reaction cup of the second station 330.

[0058] In order to further expand the sample loading scenario, specifically, the moving range of the sample loading arm 710 can extend to the outside of the workbench 100, and the sample loading arm 710 is used to grab samples stored in an external storage device outside the workbench 100, so that the sample loading arm 710 can realize external sample loading, which has a wider range of applications.

[0059] To further expand the sample addition scenario, specifically, see Figure 1 as well as Figure 2 The reagent storage device 420 also includes a second area 422 and a third area 423. The second area 422 and the third area 423 are arranged in sequence along a direction away from the first area 421. An R0 test tube can be set in the first area 421, an R1 test tube can be set in the second area 422, and an R2 test tube can be set in the third area 423. The structures of the R0 test tube, the R1 test tube, and the R2 test tube can be the same or different, and are used to store different reagents.

[0060] The robot arm also includes a first reagent arm and a second reagent arm. The first reagent arm is used to add the reagent stored in the second area 422 to the reaction cup at the third station 340, so as to realize the addition of different reagents in the first area 421 and the second area 422 to the reaction cup on the turntable 300, and to expand the type of added reagents by controlling whether the sample adding arm 710 moves to the first area 421 and whether the first reagent arm works. The second reagent arm is used to add the reagent stored in the third area 423 to the reaction cup at the measuring device 600, so as to realize the addition of the reagent in the reaction cup at the measuring device 600, and to control whether the measuring device 600 adds reagents during the measurement process by controlling whether the second reagent arm works, so as to expand the measurement application scenario.

[0061] In one example, the sample loading arm 710, the first reagent arm, and the second reagent arm may be a pipette needle, which is used to extract a sample or a reagent and add the extracted sample or reagent to a reaction cup. Of course, the structure of the sample loading arm 710, the first reagent arm, and the second reagent arm is not limited thereto, and may be other forms that meet the requirements.

[0062] To add magnetic beads, refer to Figure 1 as well as Figure 2 In a preferred embodiment, the sample analyzer 10 further includes a bead adding device 800, which is disposed in the workbench 100 and on one side of the turntable 300. The bead adding device 800 is used to load magnetic beads into reaction cups placed on the turntable 300, so as to automatically add magnetic beads to the reaction cups on the turntable 300, without the need for manual pre-adding of beads between the reaction cups placed in the reaction cup storage device 410. The bead adding device 800 is used to control whether magnetic beads are added and which reaction cups need to be added with magnetic beads, thereby improving the flexibility of adding magnetic beads, reducing the workload, and expanding the scope of adding magnetic beads.

[0063] In one example, the plurality of workstations 310 further include a fourth workstation, which is located between the first workstation 330 and the second workstation 330 , and the bead adding device 800 is disposed close to the fourth workstation to facilitate various adding operations on the reaction cups on the turntable 300 .

[0064] The bead adding device 800 has various structural forms. Specifically, the bead adding device 800 includes a storage container, a loading tube, a stirring mechanism, and a transmission mechanism, wherein: the storage container is used to store multiple magnetic beads; one end of the loading tube is connected to the storage container, and the other end of the loading tube is formed with a loading port, and the loading port is used to add magnetic beads from the outside to the bead adding device 800; the stirring mechanism is arranged in the storage container, and the stirring mechanism is used to stir the magnetic beads in the storage container and separate a part of the magnetic beads after stirring; the transmission mechanism is connected to the storage container, and the transmission mechanism is used to transfer a magnetic bead separated by the stirring mechanism to the reaction cup.

[0065] During the operation, the user adds the magnetic beads loaded into the sample analyzer 10 from the loading port to the loading tube, and transfers the magnetic beads to the storage container through the loading tube. The stirring mechanism stirs and mixes the magnetic beads in the storage container, and transfers the magnetic beads; the transfer mechanism is used to transfer the magnetic beads separated by the stirring mechanism to the reaction cup, and ensures that the number of magnetic beads transferred to the reaction cup is 1.

[0066] In one example, the loading port is provided with a flap, and when magnetic beads need to be added, only the flap needs to be opened to add, which is convenient to operate and avoids contamination. The loading tube is tilted up and down so that the magnetic beads can enter the storage container along the loading tube under the action of gravity, without pausing the sample analyzer 10 experiment or manually opening the sample analyzer 10 and reaching into the sample analyzer 10 to add magnetic beads. The structure is simple and the adding operation is convenient.

[0067] 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.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
