The reagent kit is not separated from the scheduling device during the scanning process.

[0014] In a possible implementation, the loading device further includes an in-situ detection mechanism.

[0021] It is understandable that, for the sample analysis system, the loading frequency of the reagent is much lower than the loading frequency of the sample. By setting the reused placement area, the space used to store the reagent can be used to place the sample when the reagent is not loaded. This can solve the problem that the size of the entire loading platform is too large when the sample placement area and the reagent placement area are set separately, and when the reagent does not need to be loaded, the reagent placement area is idle.

In addition, by setting the load type determined by the first identification mechanism, the load is transported back to the loading position to wait for being transported to the target position, which can solve the problem that it takes a long time to sample when the load is directly transported to the target position. In the embodiment of the present application, the control device controls the scheduling device to transport the load back to the loading position, which can release the occupation of the scheduling device by the load during the waiting period, and use the scheduling device to perform other activities, thereby improving the working efficiency of the entire sample analysis device, and avoiding the influence of setting a special cache waiting position in the sample analysis device to store the load on the miniaturization of the sample analysis device.

[0040] See also Figures 1 to 3 , Figure 1 It is a three-dimensional structural schematic diagram of a sample analysis system 1 provided in an embodiment of the present application. Figure 2 yes Figure 1 The sample analysis system 1 is shown as a schematic top view in some states. Figure 3 yes Figure 2 The sample analysis system 1 is shown in a top view in another state.

[0041] The embodiment of the present application provides a sample analysis system 1, which may include a sample analysis device 1000, a sample rack 2000, and a reagent kit 3000. The sample analysis device 1000 is a medical device for analyzing and testing samples such as blood, saliva, urine, or sweat. During the process of the sample analysis device 1000 testing the sample, some test items require the addition of a detection reagent to the sample to process the sample for subsequent testing.

[0042] Among them, the sample rack 2000 can be used to hold samples, and the test kit 3000 is used to hold reagents. The reagents 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. They can also 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.

[0044] For ease of description, Figure 1 The sample analysis device 1000 is defined as having a first direction X, a second direction Y, and a third direction Z, which are mutually perpendicular in pairs. The length direction of the sample analysis device 1000 may be parallel to the first direction X, the width direction of the sample analysis device 1000 may be parallel to the second direction Y, and the height direction of the sample analysis device 1000 may be parallel to the third direction Z. When the sample rack 2000 and the reagent box 3000 are placed in the sample analysis device 1000, the sample rack 2000 and the placement box are moved into the sample analysis device 1000 along the second direction Y, the length direction of the sample rack 2000 and the length direction of the reagent box 3000 may be parallel to the second direction Y, the width direction of the sample rack 2000 and the width direction of the reagent box 3000 may be parallel to the first direction X, and the height direction of the sample rack 2000 and the height direction of the reagent box 3000 may be parallel to the third direction Z.

[0045] In some embodiments, the sample analysis device 1000 may include a sample loading device 100, a scheduling device 200, a reagent storage device 300, a sample injection device 400, a sample suction device (not shown in the figure), and a testing device (not shown in the figure). The sample loading device 100 may include a sample loading platform 11, and the sample loading platform 11 is used by an operator to load a sample rack 2000 and a reagent kit 3000 thereon from the external space of the sample analysis device 1000 to realize the sample and reagent loading process in the sample analysis system 1; the scheduling device 200 can be used to transfer the sample rack 2000 between the sample loading platform 11 and the sample injection device 400, and the sample suction device can be used to suck the sample from the sample injection device 400. The sample loaded in the sample rack 2000 placed on the reagent rack 2000 is transferred to the reaction cup; the reagent storage device 300 is used to store the reagent kit 3000 loaded into the sample analysis device 1000; the scheduling device 200 can also be used to transfer the reagent kit 3000 between the loading platform 11 and the reagent storage device 300; the sample suction device can be used to suck the reagent loaded in the reagent kit 3000 stored on the reagent storage device 300, and transfer the sucked reagent to the reaction cup; then, the reaction liquid (a mixture of sample and reagent) in the reaction cup is detected by the testing device, so as to achieve the purpose of the sample analysis system 1 to detect the sample to be tested and obtain the test result.

[0046] In some embodiments, the sample analysis device 1000 may include a cabinet 700, which may have an operation surface 71. The operator may operate the sample analysis device 1000 facing the operation surface 71 of the sample analysis device 1000. The structural parts in the sample analysis device 1000, such as the sample loading device 100, the scheduling device 200, the reagent storage device 300, the sample injection device 400, the sample suction device and the testing device, etc., may be accommodated in the cabinet 700. The sample analysis device 1000 is an integrated cabinet, which is convenient for the operator to transfer the sample analysis device 1000. In some other embodiments, the sample analysis device 1000 may also include more or fewer components, which is not limited in the embodiments of the present application.

[0047] Illustratively, the cabinet 700 may be provided with a sample loading area 72, which may be formed by a portion of the operating surface 71 being recessed inwardly. The sample loading platform 11 may be disposed in the sample loading area 72, with one side exposed relative to the cabinet 700, so that the operator can load the sample rack 2000 and the reagent kit 3000 into the sample loading platform 11.

[0048] In some embodiments, the loading platform 11 may include a reused placement area 111 and a sample placement area 112, the sample placement area 112 includes at least one sample loading position 1121 for placing the sample rack 2000, the reused placement area 111 includes at least one reused loading position 1111, and the type of the load of the reused loading position 1111 may be the sample rack 2000 or the reagent kit 3000. It can be understood that 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 111, 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 11 is too large when the sample placement area 112 and the reagent placement area are set separately can be solved, and the reagent placement area is idle when the reagent does not need to be loaded. 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 11, 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 112 and the multiplexing placement area 111 can both extend along the first direction X. In other words, the arrangement direction of the multiple sample loading positions 1121 can be parallel to the first direction X, and the arrangement direction of the multiplexing loading positions 1111 can also be parallel to the first direction X.

[0049] In some embodiments, the multiplexed sample loading position 1111 may be provided with an in-situ detection mechanism 1112 for realizing in-situ detection of the load on the multiplexed sample loading position 1111. When the reagent kit 3000 or the sample rack 2000 is loaded into the multiplexed sample loading position 1111, the in-situ detection mechanism 1112 may be triggered. By monitoring the state of the in-situ detection mechanism 1112, the installation state of the load may be confirmed, which is beneficial to improving the automation degree of the sample analysis device 1000. The in-situ detection mechanism 1112 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] Please refer to Figure 2 and Figure 4 , Figure 4 It is a schematic diagram of the structure of a sample rack 2000, a reagent kit 3000 and a first identification mechanism 113 provided in an embodiment of the present application.

[0051] In some embodiments, the loading device 100 may further include a first identification mechanism 113, which may be used to confirm the type of the load at the multiplexed loading position 1111. The first identification mechanism 113 may be a trigger switch or an optical coupling sensor or other structural components. By utilizing the different structural features of the reagent kit 3000 and the sample rack 2000, when the reagent kit 3000 is placed at the multiplexed loading position 1111 and the sample rack 2000 is placed at the multiplexed loading position 1111, the first identification mechanism 113 may send different information to determine the type of the load. For example, the difference in length between the reagent kit 3000 and the sample rack 2000 may be utilized, so that the sample rack 2000 may trigger the first identification mechanism 113, while the reagent kit 3000 may not trigger the first identification mechanism 113. By detecting different states of the first identification mechanism 113, the type of the load at the multiplexed loading position 1111 may be confirmed. In other embodiments, the height difference between the reagent box 3000 and the sample rack 2000 may be used to make the first identification mechanism 113 have different states, which is not limited in the embodiments of the present application. In some examples, the first identification mechanism 113 may be located on the side of the reuse placement area 111 away from the sample placement area 112, and in some other embodiments, the first identification mechanism 113 may also be located at other positions, which is not limited in the embodiments of the present application.

[0052] Please refer to Figure 1 , Figures 4 to 8 As shown, Figure 5 yes Figure 1 The shown diagram is a partial structural diagram of the sample analysis system 1 in some embodiments. Figure 6 It is a structural schematic diagram of a multiplexing placement area 111, a sample rack 2000 and a reagent kit 3000 provided in an embodiment of the present application. Figure 7It is a structural schematic diagram of a drawer 114 provided in an embodiment of the present application. Figure 8 It is a structural schematic diagram of a drawer 114 and a partition 115 provided in an embodiment of the present application.

[0053] The present application schematically introduces a structure of a multiplexed sample loading station 1111. In other embodiments, the multiplexed sample loading station 1111 may also have other structures to enable the multiplexed sample loading station 1111 to carry both the sample rack 2000 and the reagent kit 3000.

[0054] In some embodiments, the sample loading device 100 further includes a drawer 114, which is movably connected to the reused placement area 111 of the sample loading platform 11, and the reused sample loading position 1111 is disposed on the drawer 114. In other words, the drawer 114 can be extended and retracted relative to the sample loading area 72 in the cabinet 700, and the reused placement area 111 can be exposed relative to the sample loading area 72 as the drawer 114 moves.

[0055] Exemplarily, the drawer 114 includes a fixedly connected pull-out portion 1141 and a placement plate 1142, the pull-out portion 1141 is located outside the sample loading area 72, the multiplexed sample loading position 1111 is provided on the placement plate 1142, and the placement plate 1142 is used to place the load (sample rack 2000 or reagent kit 3000). By providing the drawer 114, the drawer 114 can have an open position and a closed position relative to the sample loading area 72. When the drawer 114 is in the open position relative to the sample loading area 72, most of the placement plates 1142 are located outside the sample loading area 72, which is convenient for the operator to place the load in the multiplexed sample loading position 1111. When the drawer 114 is in the closed position relative to the sample loading platform 11, the placement plate 1142 is moved into the sample loading area 72, the pull-out portion 1141 can contact the operating surface 71, and the load is placed in the sample loading area 72 as the drawer 114 moves. When the drawer 114 moves to the closed position, the load can trigger the in-situ detection mechanism 1112 located inside the sample loading area 72. In some other embodiments, the drawer 114 may not be included, and this embodiment of the present application is not limited to this.

[0056] Exemplarily, the loading device 100 may further include a first detection unit (not shown in the figure), which is disposed in the loading area 72. The first detection unit is triggered when it detects that the drawer 114 moves from the open position to the closed position. The first detection unit can be used to confirm the position of the drawer 114. Among them, the first detection unit can be a trigger switch or a structure such as an optical coupling sensor, which is not limited in the embodiment of the present application. For example, the first detection unit can be disposed on the operating surface 71, and when the first detection unit moves to the closed position, the pull-out portion 1141 contacts the operating surface 71 to trigger the first detection unit, or the first detection unit can also be disposed in the loading area 72, and when the drawer 114 reaches the closed position, the placement plate 1142 abuts against the first detection unit to trigger the first detection unit. In some other embodiments, the first detection unit can also be disposed at other positions, and the embodiment of the present application does not limit the position of the first detection unit.

[0057] Exemplarily, the placement plate 1142 may include a first side 1142a and a second side 1142b that are arranged opposite to each other in the second direction Y. A limiting portion 1142c may be provided on the placement plate 1142, and the limiting portion 1142c is located between the first side 1142a and the second side 1142b. The limiting portion 1142c is used to limit the position of the reagent kit 3000. When the drawer 114 moves to the closed position, the second side 1142b of the placement plate 1142 is closer to the operation surface 71 of the cabinet 700 than the first side 1142a, and the first side 1142a of the placement plate 1142 is close to the in-situ detection mechanism 1112. It is understandable that the length of the general sample rack 2000 is longer. When the sample rack 2000 and the reagent kit 3000 are placed in the reused sample loading position 1111, the position of the reagent kit 3000 is limited by setting the limit portion 1142c and utilizing the structural difference between the reagent kit 3000 and the sample rack 2000. This allows the reagent kit 3000 to be designed as needed. The structure of the reagent kit 3000 is designed based on the reagent capacity and the reagent storage device 300 to minimize the volume of the reagent kit 3000. There is no need to change the volume of the reagent kit 3000 in order to be placed in the reused sample loading position 1111.

[0058] Exemplarily, the limiting portion 1142c may be a groove, and the groove is used to place the reagent kit 3000, and one end of the reagent kit 3000 may be embedded in the groove. In some other embodiments, the limiting portion 1142c may have other forms, which are not limited in the present embodiment.

[0059] Exemplarily, the groove may include an inner wall and an opening and a bottom wall arranged along the third direction Z, the size of the opening is larger than the size of the bottom wall, the inner wall is connected between the opening and the bottom wall, and the inner wall is inclined. In other words, the side wall of the groove is an inclined slope, and the groove can play a guiding role, making it easier to move the reagent kit 3000 into the limiting portion 1142c.

[0060] Exemplarily, the loading device 100 also includes a plurality of partitions 115 arranged along a first direction X, the partitions 115 are fixedly connected to the inner wall of the loading area 72, and a sliding groove 1151 is provided at the bottom end of the partitions 115, the sliding groove 1151 extends along the second direction Y, the number of the placement plates 1142 may also be multiple, the partitions 115 and the plurality of placement plates 1142 divide the reused placement area 111 into a plurality of reused loading positions 1111, the drawer 114 may also include a sliding block 1143, two adjacent placement plates 1142 are spaced apart, the sliding block 1143 is fixed to the second side 1142b of the placement plate 1142, the sliding block 1143 is located in the sliding groove 1151, and when the drawer 114 is in the open position, the sliding block 1143 abuts against the side of the sliding groove 1151 close to the operating surface 71. By setting the cooperation between the sliding block 1143 and the partition 115, the problem of the drawer 114 and the sample analysis device 1000 being separated when the drawer 114 is pulled open can be avoided. In the embodiment of the present application, the gap between adjacent partitions 115 can be approximately equal to the width of the reagent box 3000 and the width of the sample rack 2000. Among them, the pull-out portion 1141 and the multiple placement plates 1142 and the sliding block 1143 can be an integrated structure. In some other embodiments, the pull-out portion 1141 and the multiple placement plates 1142 and the sliding block 1143 can also form an integrated structure by welding, gluing, etc.

[0061] Exemplarily, the gap between two adjacent placement plates 1142 is greater than or equal to 0.1 mm and less than or equal to 0.5 mm. Exemplarily, the gap between two adjacent placement plates 1142 can be slightly less than 0.1 mm, such as 0.09 mm, 0.1 mm, 0.3 mm, 0.5 mm, or slightly greater than 0.5 mm, such as 0.55 mm, etc., and the embodiment of the present application is not limited to this. By setting the gap between two adjacent placement plates 1142, it is possible to avoid problems such as the gap between two adjacent placement plates 1142 being too large, the gap between adjacent multiplexing loading positions 1111 being too large, and the load being easy to shake during the drawer 114 pulling process. It is also possible to avoid problems such as the placement plates 1142 being difficult to move when the gap is too small.

[0062] In some embodiments, the sample analysis device 1000 may further include an information identification device 500, which may be used to scan information such as a reagent label on the reagent kit 3000 and a sample label on the sample rack 2000 to perform information identification. The reagent kit 3000 may include a reagent label, which may be used to identify reagent information of the reagent in the reagent kit 3000, and the reagent information may include but is not limited to reagent type, reagent remaining amount (also referred to as reagent filling amount), reagent container type, production date, shelf life, batch number, serial number, bottle opening date, and several calibration curves, etc.; the sample rack 2000 may include a sample label, which may be used to identify sample information of the sample in the sample rack 2000, and the sample information may include but is not limited to sample remaining amount (also referred to as sample filling amount), production date, shelf life, batch number, serial number, bottle opening date, and several calibration curves, etc. It is understandable that different reagents can be loaded in the reagent box 3000, and different samples can be loaded in the sample rack 2000, but the reagents in the same reagent box 3000 and the samples in the same sample rack 2000 generally belong to the same batch and have the same shelf life. By setting up the information identification process of the information identification device 500 and the sample label of the sample rack 2000 and the label of the reagent box 3000, it is easy to locate and find the required reagent box 3000 and sample rack 2000, and to timely understand the relevant information of the reagent box 3000 and the sample rack 2000, which is conducive to improving the reliability and accuracy of the detection process of the sample analysis system 1.

[0063] In some embodiments, the sample analysis device 1000 may also 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 and communicatively connected with structural parts such as the loading device 100, the scheduling device 200, the reagent storage device 300, the sample injection device 400, and the sample suction device, as well as their related components such as the in-situ detection mechanism 1112, the first identification mechanism 113, etc., 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.

[0064] For example, the control device can be electrically connected to the in-situ detection mechanism 1112. When the in-situ detection mechanism 1112 detects that a load is placed on the multiplexed loading position 1111, the control scheduling device 200 transfers the load of the multiplexed loading position 1111 to the first identification mechanism 113 based on the received load identification information, so as to use the first identification mechanism 113 to determine the type of load.

[0065] Among them, when the first detection unit detects that the drawer 114 moves from the open position to the closed position, it sends the load identification information to the control device. In the embodiment of the present application, by setting the first detection unit, the control device controls the movement of the scheduling device 200 after receiving the load identification information, thereby improving the coordination and automation of the various components in the sample analysis device 1000. In some other embodiments, the sample analysis device 1000 may not be provided with the first detection unit, and a button or other structural member may be provided on the operating surface 71, and the user can send the load identification information to the control device by pressing the button, which is not limited in the embodiment of the present application.

[0066] For example, after the first identification mechanism 113 determines the type of the load, the control device can also control the scheduling device 200 to transfer the load back to the reused sample loading position 1111 to wait for being transferred to the target position. It can be understood that in the embodiment of the present application, the control device first controls the scheduling device 200 to transfer the load from the reused sample loading position 1111 to the first identification mechanism 113, which can solve the problem that when there are multiple reused sample loading positions 1111, if the load is not moved to the first identification mechanism 113, in order to identify the type of the load, it is necessary to set up multiple first identification mechanisms 113 to identify the type of the load in each reused sample loading position 1111 one by one. It can also avoid the problem that if the load is not transferred to the first identification mechanism 113, the load in other reused sample loading positions 1111 between the reused sample loading position 1111 and the first identification mechanism 113 interferes with the detection result of the first identification mechanism 113.

[0067] In addition, after the first identification mechanism 113 determines the type of load, if the load is directly transferred to the target position, for example, when the sample rack 2000 is transferred to the sampling device 400, there may be other sample racks 2000 in the sampling device 400, and the sampling process of waiting for the sample rack 2000 also takes time. In the embodiment of the present application, the control device controls the scheduling device 200 to transfer the load back to the sample loading position 1111, which can release the occupation of the scheduling device 200 by the load during the waiting period, and use the scheduling device 200 for other activities to improve the working efficiency of the entire sample analysis device 1000, and avoid setting a special cache waiting position in the sample analysis device 1000 to store the load, which affects the miniaturization of the sample analysis device 1000. The embodiment of the present application uses the existing space to realize the cache waiting function, and can effectively and flexibly use the space in the sample analysis device 1000 according to the working process of the sample analysis device 1000.

[0068] Thereafter, for example, when the object to be loaded is the sample rack 2000, after confirming that the object to be loaded at the reused sample loading position 1111 is the sample rack 2000 and has been transferred back to the usable sample loading position 1111, the control device can also control the scheduling mechanism to transfer the sample rack 2000 to the information recognition device 500 for information scanning according to the received scanning instruction for the sample rack 2000, and transfer the sample rack 2000 back to the usable sample loading position 1111 after the scanning is completed. It can be understood that the information recognition process of the sample rack 2000 by the information recognition device 500 is relatively short, and the process of the sample taking device for the sample in the sample rack 2000 is relatively long. By arranging to transfer the sample rack 2000 back to the usable sample loading position 1111 after the scanning is completed, it is possible to avoid the sample rack 2000 from occupying the scheduling mechanism 200 during the waiting process, thereby saving the scheduling time of the entire sample analysis system 1 and improving the working efficiency of the entire sample analysis system 1.

[0069] After that, after confirming that the sample rack 2000 has completed the information scanning and has been transported back to the sample loading position 1111, the control device can also control the scheduling device 200 to transport the sample rack 2000 to the sample suction device for sample suction operation according to the received sample suction instruction for the sample rack 2000. In the embodiment of the present application, the transportation process of the sample rack 2000 is divided into several stages, and the sample rack 2000 is transported back to the sample loading position 1111 for many times, taking full account of the working time of each component in the sample analysis device 1000, and reasonably arranging to avoid too long waiting time, thereby improving the working efficiency of the entire sample analysis system 1.

[0070] See also Figure 3 , Fig. 9 and Fig.10 , Fig. 9 It is a schematic structural diagram of a sample injection device 400, an information identification device 500 and a sample rack 2000 provided in an embodiment of the present application. Fig.10 yes Fig. 9 The structure diagram of the sample injection device 400, the information identification device 500 and the sample rack 2000 shown in another viewing angle.

[0071] Exemplarily, the sample injection device 400 may include a sample injection track 41 and a driving mechanism 42, and the driving mechanism 42 may drive the sample rack 2000 to move along the sample injection track 41. The extending direction of the sample injection track 41 may be parallel to the first direction X.

[0072] Exemplarily, the information recognition device 500 and the sample suction device can be located on one side of the injection track 41, and the scheduling device 200 transfers the sample rack 2000 to the injection track 41. The driving mechanism 42 transfers the sample rack 2000 to the information recognition device 500 or the sample suction device while driving the sample rack 2000 to move along the injection track 41. In the embodiment of the present application, while the sample rack 2000 moves along the injection track 41 driven by the driving mechanism 42, the information recognition device 500 can scan the information of the sample rack 2000 to understand the batch information of the sample. No additional structural parts are required in the sample analysis device 1000 to schedule the sample rack 2000 to reach the scanning position (the area where the information recognition device 500 can perform information recognition) or the sample suction position 400a on the injection device 400. The scheduling process of the sample rack 2000 in the sample analysis device 1000 is simple and low-cost.

[0073] Exemplarily, the sample feeding device 400 may also include a second identification mechanism 43, the sample rack 2000 is loaded with sample containers, and the second identification mechanism 43 is used to identify the type of the sample container; the driving mechanism 42 moves the sample rack 2000 to the second identification mechanism 43 to identify the type of the sample container, and after the identification is completed, the sample rack 2000 is moved to the information identification device 500 for information scanning. It is understandable that the sample rack 2000 can be used to carry multiple types of sample containers, each sample container can be used to load different samples, and the operator may use a sample container without a barcode or a sample container with a barcode when using the sample analysis device 1000. In addition, some sample containers with small inner diameters may be used. By setting the second identification mechanism 43, it is used to identify different types of sample containers to avoid the situation that when sucking samples in different types of sample containers, for example, when sucking samples from sample containers with smaller inner diameters (such as micro-cups and centrifuge tubes), the conventional sampling method is still used, which will lead to insufficient sampling, and the flexibility of the sample analysis device 1000 in the process of detecting the components of the sample is effectively improved.

[0074] For example, the second identification mechanism 43 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.

[0075] In some embodiments, the sample feeding device 400 further includes a decapping mechanism 44 for performing a decapping operation on the sample container. The decapping mechanism 44 is located on one side of the sample feeding track 41. When the control device confirms that the sample container of the sample rack 2000 needs to be decapped, the driving mechanism 42 transfers the sample rack 2000 that has completed the information scanning to the decapping mechanism 44, and after the decapping operation is completed, the scheduling device 200 transfers the sample rack 2000 back to the sample loading position 1111. Thereafter, when the control device receives a sample suction instruction for the sample rack 2000, the scheduling device 200 controls the sample rack 200 to transfer it to the vicinity of the sample suction device.

[0076] In addition, for the sample rack 2000 located at the sample loading position 1121, the scheduling device 200, under the control of the control device, can first transfer the sample rack 2000 at the sample loading position 1121 to the sample injection device 400, and the driving mechanism 42 moves the sample rack 2000 to the second identification mechanism 43 to identify the type of the sample container, and after the identification is completed, the sample rack 2000 is moved to the information identification device 500 for information scanning, and after the scanning is completed, the scheduling device 200 is used to transfer the sample rack 2000 back to the sample loading position 1121. After confirming that the sample rack 2000 has completed the information scan and has been transferred back to the sample loading position 1121, the control device controls the scheduling device 200 to transfer the sample rack 2000 to the sample injection position 400a in the sample injection device 400 again according to the received sample suction instruction for the sample rack 2000, so that the sample suction device can suck the sample. When the control device confirms that the sample container of the sample rack 2000 needs to be decapped, the control device can also transfer the sample rack 2000 that has completed the information scanning to the decapping mechanism 44 through the driving mechanism 42, and after completing the decapping operation, the sample rack 2000 is transferred back to the sample loading position 1111 through the scheduling device 200. The specific transfer process is not limited in the embodiment of the present application, and can be set as needed. In the process of the scheduling device 200 transferring the sample rack 2000 to the sample suction position 400a, the scheduling device 200 can directly send the sample rack 2000 to the sample suction position 400a, or, in some other embodiments, the scheduling device 200 can also send the sample rack 2000 into the sample injection device 400, and the sample rack 2000 is driven by the driving mechanism 42 to be transferred to the sample suction position 400a, and the embodiment of the present application does not limit this.

[0077] For the sample rack 2000 in the loading platform 11, the sample rack 2000 is placed in the reuse placement area 111 and / or the sample placement area 112. The control device can transfer the sample racks 2000 in the two areas according to a plurality of preset rules. For example, the control device can transfer the sample racks 2000 in the sample loading position 1121 and the reused loading position 1111 to the target position respectively through the scheduling device 200 according to the first preset rule and the loading order of the sample racks 2000. By setting the reused placement area 111 and the sample placement area 112 to be able to place the sample rack 2000, the sample rack 2000 can be placed in the reused placement area 111 and the sample placement area 112 without additionally increasing the size of the loading platform 11. At the same time, the sample loading platform 11 can effectively improve the carrying capacity of the sample rack 2000; alternatively, the control device can also transfer the sample rack 2000 of the multiplexed sample loading position 1111 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 1121 to the target position. For example, the user can place the sample rack that needs to be processed first in the multiplexed sample loading position 1111. According to the second preset rule, the sample analysis system 1 will give priority to processing the samples in the multiplexed sample loading position 1111, thereby improving the convenience of operating the sample analysis system 1 and accelerating the processing speed of detecting urgent samples.

[0078] For another example, after confirming that the load of the multiplexed loading position 1111 is the reagent kit 3000 and has been transferred to the multiplexed loading position 1111, the control device can also control the scheduling device 200 to transfer the reagent kit 3000 to the information identification device 500 for information scanning according to the received transfer instruction for the reagent kit 3000, and transfer the reagent kit 3000 to the reagent storage device 300 after the scanning is completed. The reagent kit 3000 is not separated from the scheduling device 200 during the scanning process. A scheduling device 200 is provided in the sample analysis device 1000, so as to realize the process of taking out the reagent kit 3000 from the reused sample loading position 1111, the process of transferring the reagent kit 3000 from the reused sample loading position 1111 to the reagent storage device 300, and the process of placing the reagent kit 3000 into the reagent storage device 300. This is beneficial to simplify the number of components in the sample analysis device 1000 and improve the utilization rate of components such as the scheduling device 200. In addition, the information recognition process of the reagent label can be realized during the transportation of the reagent kit 3000, which can save space in the sample analysis device 1000 and also eliminate the need for the scheduling device 200 to take and place the reagent kit 3000 during the information recognition process. The scheduling action of the scheduling device 200 in the sample analysis device 1000 is simple.

[0079] Exemplarily, the reagent storage device 300 and the information identification device 500 are located on the same side of the sample injection track 41. In the embodiment of the present application, by reasonably designing the structure and layout of the scheduling device 200, the reagent storage device 300 and the loading platform 11 in the sample analysis device 1000, a set of scheduling devices 200 is set in the sample analysis device 1000, and the transportation process of the reagent kit 3000 and the sample rack 2000 can be realized, and the same information identification device 500 can realize the information identification of the reagent kit 3000 and the sample rack 2000, which is conducive to simplifying the number of components in the sample analysis device 1000 and improving the utilization rate of components such as the scheduling device 200.

[0080] Please refer again Figure 1 , Figure 2 and Fig.11 , Fig.11 yes Figure 1 The management interface 61 shown is a schematic diagram of the structure in some embodiments.

[0081] 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 of the loading platform 11, and each display position is used to display the status information of the load placed at the corresponding loading position on the loading platform 11.

[0082] For example, Figure 1 As shown, the sample analysis device 1000 has a total of 17 sample loading positions. The first 12 sample loading positions from left to right are sample loading positions 1121, which only support the placement of sample racks 2000; the following 5 sample loading positions are multiplexed sample loading positions 1111, which can place both sample racks 2000 and reagent kits 3000 (such as Figure 2 Correspondingly, Fig.11 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 1121 of the loading platform 11, respectively. Fig.11 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 1121. 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 1111 of the loading platform 11, respectively. Fig.11The 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 in the corresponding multiplexed sample loading position 1111. The multiplexed display position 6121 displays the reagent kit status mark when the first identification mechanism 113 determines that the load of the corresponding multiplexed sample loading position 1111 is the reagent kit 3000, and displays the sample rack status mark when the first identification mechanism 113 determines that the load of the corresponding multiplexed sample loading position 1111 is the sample rack 2000. For example, Fig.11 The multiplexed display position 6121 numbered 15 displays the reagent kit status mark, indicating that the loading object of the multiplexed loading position 1111 numbered 15 of the loading platform 11 is the reagent kit 3000; Fig.11 The multiplexed display position 6121 numbered 16 displays the sample rack status mark, indicating that the load of the multiplexed loading position 1111 numbered 16 of the loading platform 11 is the sample rack 2000 .

[0083] In some other embodiments, each display position may display an idle mark 61a when there is no object loaded at the corresponding loading position. Fig.11 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 3000 at the sample loading position, so that the user can know directly through the idle mark 61a that there is no load at the sample loading position.

[0084] The display device 600 may be a display device such as a display screen, and the status identifier may be an icon, text, etc. presented on the display screen. The control device may receive information from the in-situ detection mechanism 1112 and the first identification mechanism 113, and control the display device 600 to present different icons or texts according to different states of the in-situ detection mechanism 1112 and the first identification mechanism 113. The sample analysis device 1000 may also include structural parts such as indicator lights, and the control device may receive information from the in-situ detection mechanism 1112 and the first identification mechanism 113, and control the display lights to flash different colors to indicate different types of loads according to different states of the first identification mechanism 113.

[0085] 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 42 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 1111 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.

[0086] Similarly, the control device may also switch the display mode of the status identification of the reagent kit 3000 based on the status information of the reagent kit 3000 obtained. For example, the reagent kit 3000 has been loaded into the sample analysis device 1000 but has not yet been transferred. At this time, the display mode of the status identification on the management interface 61 may be a green border outside the reagent kit 3000 graphic and a green permanent display. When the reagent kit 3000 is transferred (for example, the scheduling device 200 drives the reagent kit 3000 to move, or the reagent kit 3000 is located in the reagent storage device 300), the reagent kit 3000 graphic on the management interface 61 may have a yellow border and a yellow permanent display to indicate that the reagent kit 3000 is in a state of being transferred. After the reagent kit 3000 completes the test, the reagent kit 3000 will be transferred to the reused sample loading position again, that is, the reagent kit 3000 is in a state of test completion. At this time, the reagent kit 3000 graphic on the management interface 61 may have a gray border and a gray permanent display to indicate that the reagent kit 3000 has completed the test. In addition, when the reagent kit 3000 fails in any process (for example, information recognition failure, failure during testing, unloading failure, etc.), that is, the reagent kit 3000 is in a faulty state, the display mode of the reagent kit 3000 status identification can be a stroke of other colors and a constant display to indicate that the reagent kit 3000 has a fault. In the embodiment of the present application, the different states of the reagent kit 3000 are identified by changing the color of the pattern of the reagent kit 3000 on the management interface 61. In other embodiments, there may be other ways, which are not limited in the embodiment of the present application.

[0087] The above are only some embodiments and implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
