Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0042] In the embodiments of the present application, the limitations of relative positional relationship, such as parallel and perpendicular, are mentioned. These limitations are all for the current technological level, rather than absolutely strict limitations, and a small amount of deviation is allowed, and approximately parallel, approximately perpendicular, etc. are all acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0044] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the three-dimensional structure of a sample analysis system 1 provided in some embodiments of the present application. Figure 2 yes Figure 1 The sample analysis system 1 is shown as a schematic top view in some states.

[0045] The embodiment of the present application provides a sample analysis system 1, which may include a sample analysis device 1000 and a sample rack 2000. The sample analysis device 1000 is a medical device for analyzing and testing samples such as blood, saliva, urine or sweat. The sample rack 2000 may be loaded with a sample container, which is used to carry the sample to be tested.

[0046] Among them, the sample analysis equipment 1000 can be a blood cell analyzer, a coagulation analyzer, a biochemical analyzer, an immunoassay analyzer, a C-reactive protein (CRP) analyzer, a smear preparation device, etc., which is not limited in the embodiments of the present application.

[0047] For ease of description, Figure 1 As shown in the perspective, the sample analysis device 1000 is defined as having a first direction Z, a second direction X, and a third direction Y, which are mutually perpendicular. The height direction of the sample analysis device 1000 can be parallel to the first direction Z, the length direction of the sample analysis device 1000 can be parallel to the second direction X, and the width direction of the sample analysis device 1000 can be parallel to the third direction Y. When the sample rack 2000 is placed in the sample analysis device 1000, the height direction of the sample rack 2000 can be parallel to the first direction Z, the width direction of the sample rack 2000 can be parallel to the second direction X, and the length direction of the sample rack 2000 can be parallel to the third direction Y. The sample rack 2000 can be moved into the sample analysis device 1000 along the third direction Y.

[0048] In some embodiments, the sample analysis device 1000 may include a loading platform 100, a scheduling device 200, a sample injection device 300, a sample suction device (not shown in the figure), and a testing device (not shown in the figure), wherein the loading platform 100 may include at least one loading position 11, and the loading position 11 is for the operator to place the sample rack 2000 from the external space of the sample analysis device 1000 on it, so as to realize the sample loading process in the sample analysis system 1; the scheduling device 200 can be used to transfer the sample rack 2000 between the loading platform 100 and the sample injection device 300, and the sample suction device can be used to suck the sample to be tested loaded in the sample container of the sample rack 2000, and transfer the sucked sample to the reaction cup, and then, the solution in the reaction cup is tested by the testing device, so as to realize the purpose of the sample analysis system 1 to detect the sample to be tested to obtain the test result. In some other embodiments, the sample analysis device 1000 may also include more or fewer components, and the embodiment of the present application is not limited to this. In some examples, the arrangement direction of the plurality of sample loading sites 11 may be parallel to the second direction X.

[0049] Exemplarily, the loading platform 100 may further include an in-situ detection mechanism 12, which is disposed in the loading position 11 and is used to detect the in-situ state of the sample rack 2000 on the loading position 11. When the sample rack 2000 is loaded into the loading position 11, the in-situ detection mechanism 12 may be triggered. By monitoring the state of the in-situ detection mechanism 12, the installation state of the sample rack 2000 on the loading position 11 may be confirmed, which is beneficial to improving the automation degree of the sample analysis device 1000. The in-situ detection mechanism 12 may be a device such as an optical coupling sensor or a trigger switch, which is not limited in the embodiments of the present application.

[0050] In some embodiments, the scheduling device 200 may be located between the sample loading platform 100 and the sample injection device 300, and both the scheduling device 200 and the sample injection device 300 are located on the side of the sample loading platform 100 away from the external space of the sample analysis device 1000. By setting the relative positions of the scheduling device 200, the sample loading platform 100 and the sample injection device 300, it is helpful to reduce the distance of the scheduling device 200 to transport the sample rack 2000, thereby improving the transportation efficiency of the sample rack 2000.

[0051] Please refer to Figures 2 to 4 , Figure 3 yes Figure 2 A partial structural schematic diagram of a sample analysis device 1000 is shown. Figure 4 yes Figure 3 The structure diagram of part of the sample analysis device 1000 shown is from another perspective.

[0052] In some embodiments, the sample introduction device 300 may include a sample introduction track 31 and a driving mechanism 32, and the driving mechanism 32 may drive the sample rack 2000 to move along the sample introduction track 31. Exemplarily, the extension direction of the sample introduction track 31 may be parallel to the second direction X, that is, the sample rack 2000 may move along the second direction X under the drive of the driving mechanism 32.

[0053] Exemplarily, a loading and unloading area 311 may be provided on the sample injection track 31 , and the loading and unloading area 311 is an area on the sample injection track 31 where the scheduling device 200 can put in and / or remove the sample rack 2000 .

[0054] Illustratively, a sample suction area 312 may be provided on the sample introduction track 31 , and when the sample rack 2000 is located in the sample suction area 312 , a sample suction device may suck the sample to be tested in the sample rack 2000 .

[0055] In some embodiments, the sample analysis device 1000 may further include an information recognition device 400 , and the sample injection track 31 may have an information recognition area 313 . When the sample rack 2000 moves into the information recognition area 313 , the information may be recognized by the information recognition device 400 .

[0056] Exemplarily, the information identification device 400 may include a scanning mechanism 41, which may be used to scan sample information such as sample labels on the sample rack 2000 to perform information scanning. The sample rack 2000 may include a sample label, which may be used to identify sample information in the sample rack 2000. The sample information may include but is not limited to sample residual quantity (also referred to as sample loading quantity here), production date, shelf life, batch number, serial number, bottle opening date, and several calibration curves. It is understandable that different samples may also be loaded in the sample rack 2000, but the samples in the same sample rack 2000 generally belong to the same batch and have the same shelf life. By setting the scanning mechanism 41 and the information scanning process of the sample label of the sample rack 2000, it is convenient to locate and find the required sample rack 2000, and timely understand the relevant information of the sample rack 2000, which is conducive to improving the reliability and accuracy of the detection process of the sample analysis system 1.

[0057] Exemplarily, the information identification device 400 may also include an identification mechanism 42, and the identification mechanism 42 is used to identify the type of sample container in the sample rack 2000. It is understandable that the sample rack 2000 may carry multiple types of sample containers, each of which may be used to load different samples. When using the sample analysis device 1000, the operator may use a sample container without a barcode, or a sample container with a barcode, or may use some sample containers with a small inner diameter, or the sample container may also include a tube body and a tube cap. For example, if a sample container with a small inner diameter (such as a microcup or a centrifuge tube) is still used in a conventional sampling method, insufficient sampling may occur, or, for another example, if a sample container including a tube cap is sucked, if the tube cap is not separated from the tube body in advance, it may cause problems such as sampling failure. The embodiment of the present application provides a recognition mechanism 42 for identifying the type of sample container to improve the flexibility and reliability of the sample analysis device 1000 in the process of detecting the components of the sample.

[0058] For example, the identification mechanism 42 can be a microcup identification sensor, which uses the height difference of the sample container for identification. The sensors are installed at different heights. When the microcup identification sensor is blocked but the conventional blood collection tube identification sensor is not blocked, it indicates that the container is a sample container with a small diameter; when the microcup identification sensor and the blood collection tube identification sensor are blocked at the same time, it indicates that the sample is a conventional blood collection tube container.

[0059] In some embodiments, the sample analysis device 1000 further includes a decapping device 500 for performing a decapping operation on the sample container. In the embodiment of the present application, when the identification mechanism 42 detects that the sample container needs to be decapped, the decapping device 500 is used to perform the decapping operation, and the operator does not need to perform manual operation, thereby improving the automation of the sample analysis device 1000. In some examples, the decapping device 500 and the information recognition device 400 are both located on the side of the sample introduction track 31 away from the scheduling device 200 to avoid interference with the movement of the internal components of the scheduling device 200 caused by the decapping device 500 and the information recognition device 400.

[0060] In some embodiments, the sample analysis device 1000 may further include a control device (not shown in the figures). The control device is the control center of the sample analysis device 1000, and various components of the entire sample analysis device 1000 can be connected using various interfaces and lines. For example, the control device can be electrically connected and communicated with structural parts such as the sample loading platform 100, the scheduling device 200, the sample injection device 300, the sample suction device, the information identification device 400, and the cover removal device 500, as well as their related components such as the in-situ detection mechanism 12 and the driving mechanism 32, so as to coordinate the coordinated work of the various components in the sample analysis device 1000 and improve the degree of automation of the sample analysis device 1000.

[0061] For example, when the control device receives the information sent by the in-situ detection mechanism 12 and confirms that the sample rack 2000 has been placed on the sample loading position 11, the control device can control the scheduling device 200 to transfer the sample rack 2000 to the information identification device 400 for information identification according to the received information identification instruction for the sample rack 2000, and transfer the sample rack 2000 that has completed information identification back to the sample loading platform 100 for caching to wait to be transferred to the sample suction device for sample suction. It is understandable that when the scheduling device 200 transfers the sample rack 2000 to the information identification device 400 for information identification, there may be other sample racks 2000 in the sampling device 300 that are being sampled, and the sampling process waiting for the sample rack 2000 also takes time, but the information identification process of the sample rack 2000 by the information identification device 400 is relatively short. In the embodiment of the present application, the scheduling device 200 is controlled by the control device to transfer the sample rack 2000 back to the loading position 11. The time difference between the time for the information identification device 400 to scan the information of the sample rack 2000 and the time difference between the sampling process of the sample rack 2000 already existing in the sampling device 300 by the sample aspiration device can be reasonably utilized to avoid the sample rack 2000 occupying the scheduling device 200 while waiting for another sample rack 2000 to be sampled, thereby saving the scheduling time of the entire sample analysis system 1 and improving the working efficiency of the entire sample analysis system 1.

[0062] Among them, the control device controls the scheduling device 200 to transfer the sample rack 2000 from the loading platform 100 to the injection track 31, and the driving mechanism 32 can drive the sample rack 2000 in the injection track 31 to move along the injection track 31 to transfer the sample rack 2000 to the information identification device 400 (that is, the sample rack 2000 arrives at the information identification area 313).

[0063] Specifically, in the embodiment of the present application, the scheduling device 200 transfers the sample rack 2000 of the loading platform 100 to the loading and unloading area 311, and the driving mechanism 32 can transfer the sample rack 2000 in the loading and unloading area 311 to the information identification area 313 for information identification. Thereafter, the scheduling device 200 can transport the sample rack 2000 that has completed information identification back to the loading platform 100 for caching. In the embodiment of the present application, by setting up the driving mechanism 32, the sample rack 2000 can move along the sample introduction track 31 during the information identification process, releasing the sample rack 2000 from occupying the scheduling device 200 during the information identification process, and the identification process of multiple sample containers in the sample rack 2000 can rely on the drive of the driving mechanism 32, and pass through the identifiable area corresponding to the identification mechanism 42 in sequence. In addition, in the embodiment of the present application, the area (loading and unloading area 311) where the scheduling device 200 takes and places the sample rack 2000 is separately arranged from the functional areas (such as the sample suction area 312, the information identification area 313, etc.) corresponding to other structural parts (such as the sample suction device, the information identification device 400, etc.), so that multiple sample racks 2000 can be placed on the sample rack 2000 at the same time. For example, one sample rack 2000 is sucked in the sample suction area 312, one sample rack 2000 is information identified in the information identification area 313, and another one or more sample racks 2000 are cached in the loading and unloading area 311 waiting to be transported by the scheduling device 200, thereby improving the detection speed in the sample analysis equipment 1000.

[0064] When the control device confirms that the sample container of the sample rack 2000 needs to be decapped, the control device transfers the sample rack 2000 that has completed information identification to the decapping device 500 through the driving mechanism 32, and after the decapping operation is completed, the sample rack 2000 is transferred back to the sample loading platform 100 for caching through the scheduling device 200. In some other embodiments, when the control device confirms that the sample container of the sample rack 2000 does not need to be decapped, the control device can also directly transfer the sample rack 2000 that has completed information identification back to the sample loading platform 100 for caching through the scheduling device 200.

[0065] Among them, after confirming that the sample rack 2000 has completed information identification and has been transported back to the sample loading position 11, the control device can control the scheduling device 200 to directly transfer the sample rack 2000 that has completed information identification on the sample loading platform 100 to the sample suction area 312 according to the received sample suction instruction for the sample rack 2000, and the driving mechanism 32 transfers the sample rack 2000 that has completed the sample suction operation in the sample suction area 312 to the loading and unloading area 311, and the scheduling device 200 transports the sample rack 2000 that has completed the sample suction operation from the loading and unloading area 311 back to the sample loading platform 100. In the embodiment of the present application, the driving mechanism 32 drives the sample rack 2000 to move in the sample suction area 312, which is conducive to avoiding the sample rack 2000 from occupying the scheduling device 200 when performing the sample suction operation. The scheduling device 200 can be used to transport other sample racks 2000, which is conducive to improving the transportation efficiency in the sample analysis device 1000 and improving the detection efficiency of the sample analysis device 1000. In some other embodiments, the scheduling device 200 may also place the sample rack 2000 on the loading platform 100 that has completed information identification outside the sample suction area 312 (i.e., the loading and unloading area 311), and the sample rack 2000 may be driven by the driving mechanism 32 to move to the sample suction device (i.e., enter the sample suction area 312), and after the sample to be tested in the sample rack 2000 is sucked, the driving mechanism 32 transfers the sample rack 2000 that has completed the sample suction operation in the sample suction area 312 to the outside of the sample suction area 312, to be transported back to the loading platform 100 by the scheduling device 200. In other words, the embodiment of the present application does not limit the specific position of the loading and unloading area 311, and the sample rack 2000 may be transported at any position. In some examples, the loading and unloading area 311 can be located between the information identification area 313 and the sample suction area 312, that is, the scheduling device 200 can place the sample rack 2000 between the information identification area 313 and the sample suction area 312 to reduce the travel of the driving mechanism 32 to drive the sample rack 2000 to move.

[0066] In the embodiment of the present application, the transport process of the sample rack 2000 is divided into several stages, and the sample rack 2000 is transported back to the sample loading position 11 multiple times. The working time of each component in the sample analysis device 1000 is fully considered, and reasonable arrangements are made to avoid long waiting time, thereby improving the working efficiency of the entire sample analysis system 1.

[0067] The embodiment of the present application exemplarily introduces the matching structure of the sample rack 2000 and the sample injection device 300. In some other embodiments, the structure of the sample injection device 300 may also be different. Correspondingly, the matching structure of the sample rack 2000 and the sample injection device 300 may also be adaptively adjusted.

[0068] For details, please refer to Figures 3 to 7 , Figure 5 yes Figure 4 A partial structural schematic diagram of the driving mechanism 32 is shown. Figure 6 yes Figure 4 A schematic structural diagram of the sample rack 2000 is shown. Figure 7 yes Figure 4 The sample rack 2000 and the locking member 322 are shown in a simplified schematic diagram.

[0069] In some embodiments, the driving mechanism 32 may include a driving component 321 and a locking component 322, wherein the locking component 322 is connected to the driving component 321, and the driving component 321 can drive the locking component 322 to move along the extension direction of the injection track 31 (i.e., the second direction X); the driving component 321 also drives the locking component 322 to move between a locked position and an unlocked position, wherein the locking component 322 is connected to the sample rack 2000 of the injection track 31 in the locked position and is disconnected from the sample rack 2000 in the unlocked position; after the driving component 321 drives the locking component 322 to move to the locked position and connect with the sample rack 2000, the sample rack 2000 is driven to move along the extension direction of the injection track 31 through the locking component 322.

[0070] Exemplarily, the sample injection device 300 may further include a carrier 33, a locking member 322 connected to one side of the carrier 33, a driving assembly 321 connected inside the carrier 33, and a through slot 34 may further be provided inside the sample injection device 300, the extension direction of the through slot 34 being parallel to the extension direction of the injection track 31 (i.e., the second direction X), and the through slot 34 passing through the injection track 31 and the carrier 33 in the first direction Z, so as to allow the locking member 322 to pass through the injection track 31 and drive the sample rack 2000 to move along the extension direction of the injection track 31. When the locking member 322 is in the locked position, the locking member 322 passes through the through slot 34 to be connected to the sample rack 2000.

[0071] Among them, the sample rack 2000 may include a locking portion that cooperates with the locking piece 322. The locking piece 322 is connected to the locking portion in the locked position to drive the sample rack 2000 to move with the locking piece 322. The locking piece 322 is disengaged from the locking portion in the unlocked position. The locking piece 322 and the sample rack 2000 can cooperate in various forms. For example, a locking groove 2001 may be provided at one end of the sample rack 2000 facing the injection track 31. When the locking piece 322 is in the locked position, the locking piece 322 abuts against the groove wall of the locking groove 2001 to be connected to the sample rack 2000 and drive the sample rack 2000 to move. When the locking piece 322 is in the unlocked position, the locking piece 322 is disengaged from the groove wall of the locking groove 2001, and the locking piece 322 is disconnected from the sample rack 2000.

[0072] Exemplarily, the driving assembly 321 may include a first transverse movement mechanism 3211 and a first lifting mechanism 3212, the locking member 322 is connected to the first lifting mechanism 3212, the first lifting mechanism 3212 is used to drive the locking member 322 to move along the first direction Z, and the first transverse movement mechanism 3211 can be used to drive the first lifting mechanism 3212 to move along the second direction X.

[0073] The driving mechanism 32 provided in the embodiment of the present application can control the first transverse movement mechanism 3211 and the first lifting mechanism 3212 to drive the locking member 322 to move transversely and upward and downward during the process of driving the sample rack 2000 to move, so that the locking member 322 moves into or out of the locking groove 2001, thereby realizing the connection and disconnection between the locking member 322 and the sample rack 2000, so as to drive the sample rack 2000 to move or release the sample rack 2000. Specifically, by controlling the movement of the first transverse movement mechanism 3211 and the first lifting mechanism 3212, the locking member 322 can be moved into the locking groove 2001, and the movement of the first transverse movement mechanism 3211 and the first lifting mechanism 3212 is controlled again to adjust the position of the locking member 322, so that the locking member 322 abuts against one side groove wall of the locking groove 2001. At this time, the locking member 322 is connected to the sample rack 2000, and then the first transverse movement mechanism 3211 is controlled to operate, and the sample rack 2000 will move in the second direction X with the locking member 322, thereby realizing the process of the driving mechanism 32 driving the sample rack 2000 to move along the extension direction of the sample injection track 31, thereby transferring the sample rack 2000 from the loading and unloading area 311 to the information identification area 313 for information identification or the sample suction area 312 corresponding to the sample suction device is sucked.

[0074] Exemplarily, the first transverse movement mechanism 3211 may include a pulley group 32111 and a first drive motor, the pulley group 32111 and the first drive motor are both connected to the carrier 33, and the first lifting mechanism 3212 is connected to the transmission belt of the pulley group 32111, and the first drive motor is used to drive the pulley group 32111 to operate, so as to drive the first lifting mechanism 3212 to slide along the second direction X through the transmission belt in the pulley group 32111. The pulley group 32111 has a stable transmission and low noise, and can make the first lifting mechanism 3212 stop smoothly after moving to a position in the second direction X, which is very suitable for use in hospitals where quietness is required, and the first transverse movement mechanism 3211 has a simple structure and low manufacturing cost. In some examples, the pulley group 32111 may include a driving wheel, a driven wheel, and a transmission belt, the driving wheel and the driven wheel are rotatably disposed on the carrier 33, the transmission belt is wound between the driving wheel and the driven wheel, the first lifting mechanism 3212 is connected to the transmission belt, the driving wheel and the first driving motor are drivingly connected to drive the driving wheel to rotate through the first driving motor, so that the transmission belt drives the first lifting mechanism 3212 to slide along the second direction X. In some other embodiments, the first transverse movement mechanism 3211 may also be other structures, which are not limited in the embodiments of the present application.

[0075] Exemplarily, the first lifting mechanism 3212 may include a mounting seat 32121, a screw rod 32122 and a bearing seat 32123, wherein the mounting seat 32121 is fixed to the transmission belt of the pulley group 32111, and when the pulley group 32111 is running, the mounting seat 32121 moves along the second direction X with the operation of the pulley group 32111, the screw rod 32122 is connected to the mounting seat 32121, and the bearing seat 32123 is sleeved on the rotating shaft of the screw rod 32122, and a shaft matching the rotating shaft of the screw rod 32122 is provided in the bearing seat 32123. The combined threaded structure, through the cooperation of the thread inside the bearing seat 32123 and the thread on the outer ring of the rotating shaft of the screw rod 32122, can transform the rotational motion of the rotating shaft of the screw rod 32122 into the linear motion of the bearing seat 32123 along the rotating shaft of the screw rod 32122 (that is, in the first direction Z), so as to realize the lifting and lowering of the bearing seat 32123. The locking member 322 is fixed to the side of the bearing seat 32123 away from the mounting seat 32121, thereby realizing the lifting and lowering process of the locking member 322. The first lifting mechanism 3212 has a simple structure and reliable performance.

[0076] Please refer to Figure 8 and Fig. 9 , Figure 8 yes Figure 2 The shown diagram is a schematic diagram of the structure of the scheduling device 200 in some embodiments. Fig. 9 It is a schematic diagram of the coordination between a scheduling device 200 and a sample rack 2000 provided in an embodiment of the present application.

[0077] In some embodiments, the scheduling device 200 may further include a base 21, a second transverse movement mechanism 22, a second lifting mechanism 23, a rotating mechanism 24 and a sampling component 25. The second transverse movement mechanism 22 is arranged on the base 21, and the second lifting mechanism 23 is connected to the second transverse movement mechanism 22. The extension direction of the second transverse movement mechanism 22 is parallel to the arrangement direction of the multiple sample racks 2000, that is, the extension direction of the second transverse movement mechanism 22 is parallel to the second direction X. The second transverse movement mechanism 22 can drive the second lifting mechanism 23 to move along the second direction X; the rotating mechanism 24 is arranged on the second lifting mechanism 23, the second lifting mechanism 23 drives the rotating mechanism 24 to move along the first direction Z, and the rotating mechanism 24 includes a second drive motor 241; the sampling component 25 is connected to the rotating shaft of the second drive motor 241, and the second drive motor 241 drives the sampling component 25 to rotate to hook the target object, such as the sample rack 2000. The embodiment of the present application does not limit the specific structures of the base 21 , the second transverse movement mechanism 22 , the second lifting mechanism 23 , the rotating mechanism 24 and the sampling member 25 .

[0078] The scheduling device 200 provided in the embodiment of the present application can drive the sampling member 25 to move horizontally, lift and rotate through the second transverse movement mechanism 22, the second lifting mechanism 23 and the rotating mechanism 24 when sampling, so as to realize the movement, lifting and rotation of the sampling member 25, thereby transferring the sampling member 25 to various target positions to pick up and place the target object. Among them, the sample analysis device 1000 in this embodiment can omit the transmission and support structure in the rotating mechanism 24, such as bearings, couplings, splines and other structures, by directly connecting the sampling member 25 to the rotating shaft of the second driving motor 241 and driving the sampling member 25 to rotate through the rotating shaft, thereby simplifying the structure of the sample analysis device 1000, reducing the space occupied by the sample analysis device 1000, and reducing the equipment cost.

[0079] Correspondingly, the sample rack 2000 may include a box body 2002 and a transporting member 2003, wherein the transporting member 2003 is convexly disposed on the box body 2002, and the transporting member 2003 is a hooking portion provided on the sample rack 2000 to be transferred and matched with the sampling member 25. The specific structures of the sampling member 25 and the transporting member 2003 may be in various forms, for example, the first end of the sampling member 25 may be connected to the rotating shaft of the second driving motor 241, and the second end of the sampling member 25 may be formed with a hooking groove 25a, so as to hook the sample rack 2000 through the hooking groove 25a, and the transporting member 2003 of the sample rack 2000 to be transferred may be a hook hand 2003a matching the hooking groove 25a on the sampling member 25, and the sampling member 25 may make the hook hand 2003a embedded in the hooking groove 25a when grabbing the sample rack 2000.

[0080] When the sampling member 25 is used to hook the sample rack 2000, the second lifting mechanism 23, the rotating mechanism 24 and the sampling member 25 can be driven by the second transverse mechanism 22 to move along the second direction X to the vicinity of the target sample rack 2000; then the second lifting mechanism 23 is controlled to make the rotating mechanism 24 and the sampling member 25 descend, and the sampling member 25 is moved to a position flush with the transport member 2003 of the sample rack 2000, and the hook groove 25a on the sampling member 25 and the hook hand 2003 of the transport member 2003 are aligned. a; then the sampling member 25 is driven to move along the first direction Z by the second lifting mechanism 23, so that the hook groove 25a drops to the bottom of the hook hand 2003a, and the sampling member 25 is rotated so that the hook groove 25a is located directly below the hook hand 2003a; finally, the sampling member 25 is driven to move upward along the first direction Z by the second lifting mechanism 23, so that the hook hand 2003a on the sample rack 2000 enters the hook groove 25a, and then the sample rack 2000 can move with the movement of the sampling member 25. When the sample rack 2000 needs to be separated from the sampling member 25, it can be realized by controlling the sampling member 25 to move downward, and the sampling member 25 is simple and convenient to operate the process of taking and placing the sample rack 2000. Specifically, the shape of the hook hand 2003a can be "L" shaped, so that the connection between the hook hand 2003a and the hook groove 25a is more stable after docking.

[0081] In some other embodiments, the sampling piece 25 may also be designed with a hook 2003a structure, and accordingly, the sample rack 2000 may also have a hook groove 25a connected to the hook 2003a on the sampling piece 25, and the hook 2003a on the sampling piece 25 is used to hook the hook groove 25a on the sample rack 2000. The specific hooking method is similar to the above process and will not be repeated here. The embodiment of the present application does not limit the specific structures of the second transverse movement mechanism 22, the second lifting mechanism 23, etc. The sampling piece 25 and the transport piece 2003 may also have other matching forms, which are not limited in the embodiment of the present application. In some other embodiments, the scheduling device 200 and the reagent box may also have other matching forms, which are not limited in the embodiment of the present application.

[0082] For some embodiments, please refer to Figure 1 The loading platform 100 may include a sample placement area 100a and a multiplexing placement area 100b. The loading position 11 mentioned above may include at least one sample loading position 11a and at least one multiplexing loading position 11b. The sample loading position 11a is located in the sample placement area 100a. The sample loading position 11a is used to place the sample rack 2000. The multiplexing loading position 11b is located in the multiplexing placement area 100b. The loading type of the multiplexing loading position 11b can be a sample rack 2000 or a test kit.

[0083] It is understandable that in the sample analysis device 1000, some test items will require the addition of detection reagents to the sample to process the sample for subsequent testing. The test kit is used to contain reagents, which are also called biochemical reagents or test drugs. They can be specific detection reagents that cooperate with the sample to be tested to realize the analysis process of a certain component in the sample, or they can be calibrators, quality control products or freeze-dried reagents, etc. The term reagent in the embodiments of the present application should be understood broadly without specific limitation.

[0084] For the sample analysis system 1, the loading frequency of the reagent is much lower than the loading frequency of the sample. By setting the reused placement area 100b, the purpose of placing the sample in the space used for storing the reagent when the reagent is not loaded can be achieved, and the problem that the size of the entire loading platform 100 is too large when the sample placement area 100a and the reagent kit placement area are set separately, and the reagent kit placement area is idle when the reagent does not need to be loaded, etc., can be solved. The embodiment of the present application increases the capacity of the sample analysis device 1000 for the sample rack 2000 without increasing the size of the loading platform 100, increases the detection amount of the sample, and improves the utilization rate of the space in the sample analysis device 1000. In some examples, the sample placement area 100a and the reused placement area 100b can both extend along the second direction X. In other words, the arrangement direction of the multiple sample loading positions 11a can be parallel to the second direction X, and the arrangement direction of the multiple reused loading positions 11b can also be parallel to the second direction X.

[0085] When the control device confirms that the object loaded in the reused sample loading position 11 b is a sample rack 2000 , the control device sequentially transfers the sample racks 2000 in the sample placement area 100 a and the reused placement area 100 b to the sample suction device through the scheduling device 200 according to a preset rule. For example, the control device can transfer the sample racks 2000 of the sample loading position 11a and the reused loading position 11b to the target position in sequence through the scheduling device 200 according to the first preset rule and in accordance with the loading order of the sample racks 2000. By setting the reused placement area 100b and the sample placement area 100a to be able to place the sample racks 2000, the loading capacity of the loading platform 100 for the sample racks 2000 can be effectively improved without additionally increasing the size of the loading platform 100. Alternatively, the control device can also transfer the sample rack 2000 of the reused loading position 11b to the target position through the scheduling device 200 according to the second preset rule, and then transfer the sample rack 2000 of the sample loading position 11a to the target position. For example, the user can place the sample rack that needs to be processed first on the reused loading position 11b. According to the second preset rule, the sample analysis system 1 will give priority to processing the samples in the reused loading position 11b, thereby improving the convenience of operation of the sample analysis system 1 and accelerating the processing speed of detecting urgent samples. The embodiment of the present application does not limit the specific transportation rules within the sample analysis device 1000.

[0086] Please refer to Figure 1 and Fig.10 , Fig.10 yes Figure 1 The management interface 61 shown is a schematic diagram of the structure in some embodiments.

[0087] In some embodiments, the sample analysis device 1000 may include a display device 600, and the control device may control the display device 600 to display a management interface 61; the management interface 61 may include multiple display positions, and the multiple display positions correspond one by one to multiple loading positions 11 of the loading platform 100, and each display position is used to display the status information of the load placed at the corresponding loading position 11 on the loading platform 100.

[0088] For example, Figure 1 As shown, the sample analysis device 1000 has a total of 17 sample loading positions 11. From left to right, the first 12 sample loading positions 11 are sample loading positions 11a, which only support the placement of sample racks 2000; the next five sample loading positions 11 are multiplexed sample loading positions 11b, which can place both sample racks 2000 and reagent kits. Fig.10 As shown, the management interface 61 includes a sample position display area 611 and a multiplexed position display area 612. The sample position display area 611 includes a plurality of sample display positions 6111. The plurality of sample display positions 6111 correspond to the plurality of sample loading positions 11a of the loading platform 100, respectively. Fig.10 The display positions numbered 1-12 are all sample display positions 6111, and each sample display position 6111 is used to display the status information of the sample rack 2000 placed at the corresponding sample loading position 11a. The multiplexed position display area 612 includes a plurality of multiplexed display positions 6121, and the plurality of multiplexed display positions 6121 correspond to the plurality of multiplexed loading positions 11b of the loading platform 100 one by one, such as Fig.10 The display positions numbered 12-17 are all multiplexed display positions 6121, and each multiplexed display position 6121 is used to display the status information of the load placed on the corresponding multiplexed sample loading position 11b. The multiplexed display position 6121 displays the reagent kit status mark when it is determined that the load of the corresponding multiplexed sample loading position 11b is a reagent kit, and displays the sample rack status mark when it is determined that the load of the corresponding multiplexed sample loading position 11b is a sample rack 2000. For example, Fig.10 The multiplexed display position 6121 numbered 15 displays a reagent kit status mark, indicating that the loading object of the multiplexed loading position 11b numbered 15 of the loading platform 100 is a reagent kit; Fig.10 The multiplexed display position 6121 numbered 16 displays a sample rack status mark, indicating that the object loaded at the multiplexed sample loading position 11 b numbered 16 of the sample loading platform 100 is the sample rack 2000 .

[0089] In some other embodiments, each display position may display an idle mark 61a when the corresponding loading position 11 has no load. Fig.10 The display positions numbered 8 and 17 are displayed with an idle mark 61a, indicating that there is no sample rack 2000 or reagent kit in the sample loading position 11 at present, so that the user can know directly through the idle mark 61a that there is no load in the sample loading position 11.

[0090] The display device 600 may be a display device such as a display screen, and the status indicator may be an icon or text displayed on the display screen. The control device may control the display device 600 to display different icons or texts to indicate the type of the load. The sample analysis device 1000 may also include a structure such as an indicator light, and the control device may control the display light to flash different colors to indicate the type of the load.

[0091] In addition, the control device can also switch the display mode of the status identification of the sample rack 2000 based on the acquired status information of the sample rack 2000. For example, the sample rack 2000 has been loaded into the sample analysis device 1000 but has not been transferred. At this time, the display mode of the status identification on the management interface 61 can be that there is a green border outside the sample rack 2000 graphic and the green color is always displayed. When the sample rack 2000 is transferred (for example, the scheduling device 200 drives the sample rack 2000 to move, or the driving mechanism 32 drives the sample rack 2000 to move), the sample rack 2000 graphic on the management interface 61 can be yellow The border and yellow are always displayed to indicate that the sample rack 2000 is in a state of being transferred. When the sample rack 2000 completes the test, the sample rack 2000 will be transferred to the reused sample loading position 11b again, that is, the sample rack 2000 is in a state of test completion. At this time, the sample rack 2000 graphic on the management interface 61 can be gray stroked and gray is always displayed to indicate that the sample rack 2000 has completed the test. In addition, when the sample rack 2000 fails in any process (for example, scanning failure, failure during testing, unloading failure, etc.), the sample rack 2000 is in a faulty state, and the display mode of the state identification of the sample rack 2000 can be a stroke of other colors and a constant display to indicate that the sample rack 2000 has failed. In the embodiment of the present application, the different states of the sample rack 2000 are identified by changing the color of the pattern of the sample rack 2000 on the management interface 61. In other embodiments, there may be other ways, which are not limited in the embodiment of the present application.

[0092] Similarly, the control device can also switch the display mode of the reagent box status mark based on the status information of the reagent box obtained. For example, the reagent box has been loaded into the sample analysis device 1000 but has not been transported. At this time, the display mode of the status mark on the management interface 61 can be a green border outside the reagent box graphic and green is always displayed. When the reagent box is transported, the reagent box graphic on the management interface 61 can be a yellow border outside and yellow is always displayed to indicate that the reagent box is in a state of being transported. When the reagent box completes the test, the reagent box graphic on the management interface 61 can be gray strokes and gray is always displayed to indicate that the reagent box has completed the test. In addition, when the reagent box fails in any process (for example, information recognition failure, test failure, unloading failure, etc.), that is, the reagent box is in a faulty state, the display mode of the reagent box status mark can be other colors of strokes and always displayed to indicate that the reagent box has failed. In the embodiment of the present application, the different states of the reagent box are identified by changing the color of the pattern of the reagent box on the management interface 61. In other embodiments, there may be other ways, and the embodiment of the present application is not limited to this. The embodiments of the present application are introduced in detail above.
