Description

Technical Field

[0001] The present invention relates to the field of medical testing, and particularly to a sample analysis system and a sample analysis method. Background Art

[0002] In the field of medical diagnosis, with the increasing automation of testing laboratories, the demand for automated testing is also growing. A sample analyzer is used to test samples such as blood. The samples are generally placed on a sample rack and transported through a track, a belt, etc. to achieve a streamlined automated testing operation. By connecting multiple sample analysis instruments through a production line, unified management and scheduling of all samples can be carried out, thereby improving the efficiency of sample analysis.

[0003] In the existing production line type sample analysis system, there are usually various sample analyzers, such as a blood cell analyzer and a specific protein analyzer, such as CRP (C-reaction protein), SAA (Serum amyloid A), PCT (Procalcitonin), etc. Since the detection demand for blood cell analysis is large, while the detection demand for specific protein analysis is small, at least two blood cell analyzers are usually configured on the production line.

[0004] A sample may require the detection of both a blood cell analyzer and a specific protein analyzer at the same time. However, the single sample detection time of the blood cell analyzer is short, while the single sample detection time of the specific protein analyzer is long. Usually, the test tube rack loaded with samples that require the detection of both a blood cell analyzer and a specific protein analyzer is first scheduled to enter the blood cell analyzer for a complete blood count test. According to different scheduling strategies, it may be first transferred to the first blood cell analyzer or first scheduled to enter the second blood cell analyzer. The test tube rack after being tested by the blood cell analyzer will stay in the unloading area of the blood cell analyzer waiting for scheduling for the next test. When there are speed differences among multiple analyzers, there may be test tube racks staying in each unloading area, and even multiple test tube racks may be in the same unloading area. At this time, it may occur that the unloading area of the blood cell analyzer slows down or stops due to not being processed in time.

[0005] It can be seen that in the existing production line type sample analysis system, due to the mismatch in the detection speeds of the blood cell analyzer and the specific protein analyzer, the efficiency of the production line type sample analysis system is low. Summary of the Invention

[0018] The first unloading buffer area corresponding to the first sample analyzer receives the detected sample racks from the first feeding channel, and the second unloading buffer area corresponding to the second sample analyzer receives the detected sample racks from the first feeding channel;

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0030] An embodiment of the present invention provides a sample analysis system. Figure 1 The figure shows a schematic diagram of a sample analysis system according to an embodiment of the present invention. As Figure 1 shown, the sample analysis system includes a first sample analyzer 110, a second sample analyzer 120, a sample transfer device, and a control device ( Figure 1 not shown in the figure).

[0031] The sample transfer device 130 includes: a transfer mechanism having a transfer channel 130, the transfer mechanism being configured to transfer a sample rack with a sample placed thereon in the transfer channel; a first feeding mechanism having a first feeding channel 140 and a second feeding mechanism having a second feeding channel 150, the first feeding mechanism and the second feeding mechanism being arranged along the transfer direction of the transfer channel 130 and respectively configured to transfer the sample rack from the transfer channel 130 to the first feeding channel 140 and the second feeding channel 150; a first unloading buffer area 210 located between the first feeding channel 140 and the transfer channel 130 and a second unloading buffer area 220 located between the second feeding channel 150 and the transfer channel 130, which are respectively configured to store at least one detected sample rack unloaded from the first feeding channel 140 and the second feeding channel 150; a first unloading mechanism and a second unloading mechanism, which are respectively configured to transfer the sample racks on the first unloading buffer area 210 and the second unloading buffer area 220 to the transfer channel 130.

[0032] The first sample analyzer 110 and the second sample analyzer 120 are respectively arranged corresponding to the first feeding mechanism and the second feeding mechanism, so that the detection areas of the first sample analyzer 110 and the second sample analyzer 120 are respectively located in the first feeding channel 140 and the second feeding channel 150, so that the first sample analyzer 110 and the second sample analyzer 120 can correspondingly detect the samples on the sample racks transferred to the first feeding channel 140 and the second feeding channel 150.

[0033] The control device is electrically connected to the sample transfer device and controls the operation of the sample transfer device, and is configured to: when there are sample racks to be unloaded on both the first unloading buffer 210 and the second unloading buffer 220 at the same time, determine the outermost sample rack on the first unloading buffer 210 or the second unloading buffer 220 as the first sample rack to be unloaded according to a preset rule, and control the corresponding unloading mechanism to transfer the first sample rack to be unloaded from the corresponding unloading buffer to the transfer channel 130; wherein, the outermost sample rack is the sample rack closest to the transfer channel on the corresponding unloading buffer.

[0034] In an embodiment of the present invention, the first loading buffer and / or the second loading buffer are configured to be able to store multiple sample racks.

[0035] In an embodiment of the present invention, the first sample analyzer and the second sample analyzer are the same sample analyzer, for example, both are hematology analyzers for blood routine detection or specific protein analyzers for specific protein detection or analyzers integrating blood routine detection and specific protein detection.

[0036] In a sample analysis system, there are multiple sample analyzers. Each sample analyzer can perform one or more detections on samples, and the detection time of each sample analyzer for samples may be different. The capacity of the sample rack / sample in the sample analysis system is limited. If the sample rack / sample enters the transfer channel from the unloading buffer of the sample analyzer disorderly, it may be heavily stacked in the transfer channel or at a sample analyzer with a long detection time, resulting in too many samples in the sample analysis system and causing some sample analyzers to have to stop detection. In the embodiment of the present invention, the sample racks entering the transfer channel from the unloading buffer of the sample analyzer are planned. Especially when there are sample racks to be unloaded on both the first unloading buffer and the second unloading buffer at the same time, the first sample rack to be unloaded is determined according to a preset rule, and the first sample rack to be unloaded is transferred to the transfer channel, which can avoid the stacking of sample racks / samples in the sample analysis system, avoid the sample analyzers from being forced to stop, make full use of the detection ability of the sample analyzers, and improve the efficiency of the sample analysis system.

[0037] In an embodiment of the present invention, the preset rule has nothing to do with the time when the sample rack enters the corresponding unloading buffer area.

[0038] In a traditional sample analysis system, after the sample analyzer finishes detecting a sample, the sample rack enters the unloading buffer area, and then enters the transmission channel in sequence according to the time sequence of entering the unloading buffer area. However, in the present invention, the preset rule has nothing to do with the time when the sample rack enters the corresponding unloading buffer area.

[0039] The following will detail various implementation manners in which the control device in the present invention determines the sample rack to be unloaded first according to the preset rule.

[0040] In an embodiment of the present invention, the preset rule is related to the number of sample racks or samples stored in the unloading area of the sample analyzer. For example, when the control device is configured to determine the sample rack to be unloaded first according to the preset rule: respectively obtain the number of sample racks or samples stored in the first unloading buffer area 210 and the second unloading buffer area 220; determine the outermost sample rack on the unloading buffer area storing more sample racks or samples as the sample rack to be unloaded first. That is, when more sample racks or samples are stored in the first unloading buffer area 210, unload the sample rack on the first unloading buffer area 210 first; when more sample racks or samples are stored in the second unloading buffer area 220, unload the sample rack on the second unloading buffer area 220 first.

[0041] Generally in a sample analysis system, in the same unloading buffer area, the sample racks enter and exit in the first-in first-out order, that is, the sample rack that first enters the unloading buffer area from the sample analyzer first leaves the unloading buffer area and enters the transmission channel. And the sample rack that enters the unloading buffer area earlier is closer to the transmission channel than the sample rack that enters the unloading buffer area later. The sample rack closest to the transmission channel is the outermost sample rack.

[0042] In the above embodiments of the present invention, the sample rack to be unloaded first is determined according to the number of sample racks or samples stored in the unloading buffer. Since the number of sample racks or samples that can be stored in the unloading buffer of the sample analyzer is limited, if the sample racks or samples on the unloading buffer reach the upper limit, the other sample racks that have been detected by the sample analyzer cannot enter the unloading buffer of the sample analyzer. The number of sample racks that can be accommodated in the feeding channel corresponding to each sample analyzer is limited, usually one or two. If only one sample rack can be accommodated, that is, only one sample rack is being detected. After the samples on this sample rack are detected but cannot enter the unloading buffer, other sample racks cannot enter the sample analyzer for analysis, and the sample analyzer has to stop waiting for the sample rack in the unloading area to be unloaded, that is, the sample analyzer is forced to stop. If the sample analyzer is forced to stop, the other sample racks waiting to enter the sample analyzer can only stay on the transmission channel, which may cause the transmission channel to be unable to transport other sample racks or samples, resulting in the downtime of the entire sample analysis system.

[0043] Figure 2 The following shows a schematic diagram of the sample analysis system according to an embodiment of the present invention. As Figure 2 shown, the sample analysis system includes a first sample analyzer 110, a first unloading buffer 210, a second sample analyzer 120, and a second unloading buffer 220. The first unloading buffer 210 receives the sample racks detected by the first sample analyzer 110 from the feeding channel 140, and the second unloading buffer 220 receives the sample racks detected by the second sample analyzer 120 from the feeding channel 150. Usually, the width of the transmission channel of the sample analysis system can only accommodate one sample rack at the same time. If the buffer quantity of the first unloading buffer 210 reaches the upper limit after the sample rack 2001 enters the first unloading buffer 210, since the number of sample racks that can be accommodated in the feeding channel is limited, usually one or two. If the feeding channel 140 of the sample analyzer can only accommodate one sample rack, then the sample rack 2002 after being detected by the first analyzer 110 cannot enter the first unloading buffer 210, and the sample rack 2003 cannot enter the sample analyzer for analysis, resulting in the first sample analyzer 110 being forced to stop, and the sample rack 2003 can only stay on the transmission channel, which may cause the downtime of the entire sample analysis system.

[0044] In the embodiments of the present invention, the outermost sample rack on the unloading buffer storing more sample racks or samples is used as the sample rack to be unloaded first, which can prevent the sample analyzer from being forced to stop due to the sample racks or samples on the unloading buffer reaching the storage upper limit, and can avoid the downtime of the sample analysis system.

[0045] In another embodiment of the present invention, the preset rule is related to the remaining detection mode information of the samples on each sample rack stored in the unloading area of the sample analyzer. A sample having a remaining detection mode indicates that the sample needs to be further detected. For example, it needs to be transported to the third sample analyzer of the sample analysis system for detection.

[0046] In this case, the control device is configured, for example, to when determining to unload the sample rack first according to the preset rule: respectively obtain the remaining detection mode information of the samples on at least one sample rack, especially the outermost sample rack, stored in the first unloading buffer 210 and the second unloading buffer 220, where the remaining detection mode information includes at least one of the number of remaining detection modes, the priority of the remaining detection modes, and the test duration of the remaining detection modes; determine the sample rack to be unloaded first according to the remaining detection mode information of the first unloading buffer 210 and the second unloading buffer 220.

[0047] In one embodiment, the control device is configured to when determining the sample rack to be unloaded first according to the remaining detection mode information of the first unloading buffer and the second unloading buffer: use the unloading buffer with a larger number of remaining detection modes, a higher priority, or a longer test duration of the samples on the sample racks stored in the first unloading buffer and the second unloading buffer as the first unloading buffer; after determining the first unloading buffer, use the outermost sample rack as the sample rack to be unloaded first.

[0048] In the embodiment of the present invention, the remaining detection modes include at least one of retesting of blood routine, C-reactive protein detection, serum amyloid A detection, smear preparation, glycosylation detection, and erythrocyte sedimentation rate detection in order from high to low priority, that is, the remaining detection modes are the items to be detected for the sample.

[0049] Generally, all samples need to be tested for blood routine, but only some need to be tested for specific proteins, glycosylation, erythrocyte sedimentation rate, etc. When the test results of blood routine, glycosylation, etc. deviate greatly from the normal range, the sample also needs to be smeared for manual reexamination by medical staff. Since only some samples need subsequent various detections, other sample analyzers may be idle for a certain period of time.

[0050] The remaining detection mode information includes the number of remaining detection modes, the priority of the remaining detection modes, and the test duration of the remaining detection modes, and the priority of the remaining detection modes includes multiple priorities from high to low.

[0051] The number of remaining detection modes can be the number of items to be detected. The number of remaining detection modes of the samples on the sample rack can be the number of items to be detected for all the samples on each sample rack. For example, for two sample racks, sample A1 on sample rack A still needs to be detected for 1 item, sample A2 still needs to be detected for 2 items, and sample B1 on sample rack B still needs to be detected for 1 item. Then the number of remaining detection modes of sample rack A is 3, and the number of remaining detection modes of sample rack B is 1.

[0052] The more the number of remaining detection modes of a sample rack, the more items on the sample rack that have not been detected. Therefore, the unloading buffer area where the sample rack with more remaining detection modes is located is used as the first unloading buffer area, and the outermost sample rack in the first unloading buffer area goes to the next sample analyzer through the transmission channel. This can make the sample rack with more remaining detection modes go to the next sample analyzer as soon as possible, reduce the residence time of this sample rack in the sample analysis system, help reduce the total number of sample racks or samples in the sample analysis system, and improve the efficiency of the sample analysis system.

[0053] The items to be detected for each type of sample may be different, and the test duration required for each type of detection item is different.

[0054] The unloading buffer area where the sample rack with a longer test duration for the remaining detection mode is located is used as the first unloading buffer area, and the outermost sample rack in the first unloading buffer area goes to the next sample analyzer through the transmission channel. This reduces the residence time of this sample rack in the sample analysis system, helps reduce the total number of sample racks or samples in the sample analysis system, improves the efficiency of the sample analysis system, and at the same time is conducive to the samples on this sample rack getting the test report as soon as possible.

[0055] Among multiple remaining detection modes, the priorities are also different. Usually, all samples need to undergo blood routine tests. If the results of the blood routine test deviate too much from the normal value, the sample needs to be retested for blood routine. The priority of blood routine retest is usually the highest. For example, when the sample rack in the first unloading area, especially the outermost sample rack, has the remaining measurement mode of blood routine retest, while the sample rack in the second unloading area, especially the outermost sample rack, does not have the remaining measurement mode of blood routine retest and only has other remaining measurement modes with lower priorities, then the sample rack in the first unloading area is unloaded to the transmission channel first.

[0056] According to the specific types of sample analyzers in the sample analysis system or the items to be detected for the samples, the priority of the remaining detection modes can be adjusted, which will not be elaborated here.

[0057] Take the unloading buffer area where the sample rack with a higher priority among the remaining detection modes is located as the first unloading buffer area, and make the outermost sample rack in the first unloading buffer area go to the next sample analyzer through the transmission channel, so that the sample rack with the remaining detection mode having a higher priority can also go to the next sample analyzer as soon as possible, thereby making full use of the detection capabilities of the subsequent sample analyzers, reducing the residence time of the sample rack in the sample analysis system, helping to reduce the total number of sample racks or samples in the sample analysis system, and improving the efficiency of the sample analysis system.

[0058] The sample analysis system can determine the first unloading sample rack according to at least one of the number of remaining detection modes, the test duration of the remaining detection modes, and the priority of the remaining detection modes, which can improve the efficiency of the sample analysis system.

[0059] In the embodiment of the present invention, if the control device determines the first unloading sample rack according to the number of remaining detection modes of the samples on the sample racks in the unloading buffer area, and the number of remaining detection modes of the samples on the sample racks stored in the first unloading buffer area and the second unloading buffer area is the same, then:

[0060] Take the unloading buffer area where the samples on the stored sample racks have a higher priority of the remaining detection modes as the first unloading buffer area, or

[0061] Take the unloading buffer area where the samples on the stored sample racks have a longer test duration of the remaining detection modes as the first unloading buffer area, or

[0062] Take the unloading buffer area where the samples on the outermost sample rack have the largest number of remaining detection modes as the first unloading buffer area.

[0063] After determining the first unloading buffer area, take the outermost sample rack as the first unloading sample rack.

[0064] That is to say, if the first unloading sample rack is determined according to the number of remaining detection modes of the samples on the sample racks in the unloading buffer area, and the number of remaining detection modes of the samples on the sample racks stored in the first unloading buffer area and the second unloading buffer area is the same, then the first unloading buffer area can be determined according to the priority of the remaining detection modes or the measurement duration of the remaining detection modes, so as to determine the first unloading sample rack. Or the first unloading sample rack can also be determined according to the number of remaining detection modes, priority or test duration of the samples on the outermost sample rack.

[0065] In the embodiment of the present invention, if the control device determines the first unloading sample rack according to the priority of the remaining detection modes of the samples on the sample racks in the unloading buffer area, and the highest priorities of the remaining detection modes of the samples on the sample racks stored in the first unloading buffer area and the second unloading buffer area are the same, then:

[0066] The unloading buffer area with a larger number of remaining detection modes of the samples on the stored sample racks is used as the first unloading buffer area, or

[0067] The unloading buffer area with a longer measurement duration of the remaining detection modes of the samples on the stored sample racks is used as the first unloading buffer area, or

[0068] The unloading buffer area with a higher priority of the remaining detection modes of the samples on the outermost sample rack is used as the first unloading buffer area.

[0069] After determining the first unloading buffer area, the outermost sample rack is used as the first unloading sample rack.

[0070] In an embodiment of the present invention, if the control device determines the first unloading sample rack according to the test duration of the remaining detection modes of the samples on the sample racks in the unloading buffer area, and the maximum values of the test durations of the remaining detection modes of the samples on the sample racks stored in the first unloading buffer area and the second unloading buffer area are the same, then:

[0071] The unloading buffer area with a larger number of remaining detection modes of the samples on the stored sample racks is used as the first unloading buffer area, or

[0072] The unloading buffer area with a higher priority of the remaining detection modes of the samples on the stored sample racks is used as the first unloading buffer area.

[0073] After determining the first unloading buffer area, the outermost sample rack is used as the first unloading sample rack.

[0074] In practical applications, the number of remaining detection modes, the highest priority of the priority, and the maximum value of the test duration of the samples on the sample racks in different unloading buffer areas may be the same. For the convenience of description, the number of remaining detection modes, the highest priority of the priority, and the maximum value of the test duration can be collectively referred to as judgment factors. Then, when one of the judgment factors is the same, the first unloading sample rack can be confirmed according to the other two judgment factors.

[0075] In another embodiment of the present invention, the preset rule is related to the remaining detection mode information of the samples on the outermost sample rack stored in the unloading area of the sample analyzer. Correspondingly, the control device is configured to, when determining the first unloading sample rack according to the preset rule: respectively obtain the remaining detection mode information of the samples on the outermost sample racks stored in the first unloading buffer area and the second unloading buffer area, where the remaining detection mode information includes at least one of the number of remaining detection modes, the priority of the remaining detection modes, and the test duration of the remaining detection modes; determine the first unloading sample rack according to the remaining detection mode information of the outermost sample racks in the first unloading buffer area and the second unloading buffer area.

[0076] Further, when the control device is configured to determine the sample rack to be unloaded first according to the remaining detection mode information of the outermost sample racks in the first unloading buffer and the second unloading buffer: the outermost sample rack in the first unloading buffer and the second unloading buffer that has more remaining detection modes or has a higher-priority remaining detection mode or has a longer remaining detection mode test duration is determined as the sample rack to be unloaded first.

[0077] The sample analysis system can determine the sample rack to be unloaded first according to any one of the number of remaining detection modes of the samples in the outermost sample rack, the test duration of the remaining detection modes, and the priority of the remaining detection modes, which can improve the efficiency of the sample analysis system.

[0078] In the embodiment of the present invention, if the control device determines the sample rack to be unloaded first according to the number of remaining detection modes of the samples in the outermost sample rack of the unloading buffer, and the number of remaining detection modes of the samples on the outermost sample racks in the first unloading buffer and the second unloading buffer is the same, then:

[0079] The unloading buffer with a higher-priority remaining detection mode of the samples on the stored outermost sample rack is used as the first unloading buffer, or

[0080] The unloading buffer with a longer measurement duration of the remaining detection mode of the samples on the stored outermost sample rack is used as the first unloading buffer.

[0081] That is to say, if the outermost sample racks on the first unloading buffer and the second unloading buffer both have remaining detection modes and the number of remaining detection modes is the same, then the outermost sample rack in the first unloading buffer and the second unloading buffer that has a higher-priority remaining detection mode or has a longer waiting duration of the remaining detection mode is determined as the sample rack to be unloaded first.

[0082] In the embodiment of the present invention, if the control device determines the sample rack to be unloaded first according to the priority of the remaining detection modes of the samples in the outermost sample rack of the unloading buffer, and the priorities of the remaining detection modes of the samples on the outermost sample racks in the first unloading buffer and the second unloading buffer are the same, then:

[0083] The unloading buffer with a larger number of remaining detection modes of the samples on the stored outermost sample rack is used as the first unloading buffer, or

[0084] The unloading buffer with a longer test duration of the remaining detection mode of the samples on the stored outermost sample rack is used as the first unloading buffer.

[0085] That is, if the outermost sample racks on the first unloading buffer and the second unloading buffer have the same remaining detection patterns with the highest priority, the outermost sample rack among the outermost sample racks on the first unloading buffer and the second unloading buffer that has more remaining detection patterns or has more remaining detection patterns with the same highest priority or has a longer waiting duration for the remaining detection patterns is determined as the first unloading sample rack. For example, when the outermost sample rack on the first unloading buffer has two samples that need to be retested for blood routine and one sample that needs CRP measurement, while the outermost sample rack on the second unloading buffer has three samples that need to be retested for blood routine, that is, both outermost sample racks on the two unloading buffers have samples that need to be retested for blood routine. Since the outermost sample rack on the second unloading buffer has more samples that need to be retested for blood routine, the outermost sample rack on the second unloading buffer is preferentially unloaded.

[0086] In the embodiment of the present invention, if the control device determines the first unloading sample rack according to the test duration of the remaining detection patterns of the samples on the outermost sample rack of the unloading buffer, and the test durations of the remaining detection patterns of the samples on the outermost sample rack of the first unloading buffer and the outermost sample rack of the second unloading buffer are the same, then:

[0087] The unloading buffer with more remaining detection patterns of the samples on the stored outermost sample rack is used as the first unloading buffer, or

[0088] The unloading buffer with a higher priority of the remaining detection patterns of the samples on the stored outermost sample rack is used as the first unloading buffer.

[0089] That is, if the outermost sample racks on the first unloading buffer and the second unloading buffer have the same remaining detection patterns with the longest waiting duration, the outermost sample rack among the outermost sample racks on the first unloading buffer and the second unloading buffer that has more remaining detection patterns or has a higher-priority remaining detection pattern is determined as the first unloading sample rack.

[0090] In practical applications, the number, priority, and test duration of the remaining detection patterns of the samples on the outermost sample racks of different unloading buffers may be the same. For ease of description, the number, priority, and test duration of the remaining detection patterns can be collectively referred to as judgment factors. Then, when one of the judgment factors is the same, the other two judgment factors can be used for judgment to confirm the first unloading sample rack.

[0091] In an embodiment of the present invention, when there is no remaining mode for the outermost sample rack, scheduling is performed according to the inner sample rack. That is, if neither of the outermost sample racks on the first unloading buffer and the second unloading buffer has a remaining detection mode, the remaining detection mode information of the samples on the inner sample racks stored on the first unloading buffer and the second unloading buffer is obtained respectively, where the inner sample rack is the sample rack between the corresponding outermost sample rack and the corresponding feeding channel on the corresponding unloading buffer; according to the remaining detection mode information of the inner sample racks on the first unloading buffer and the second unloading buffer, the sample rack to be unloaded first is determined. The specific determination method is similar to the above and will not be elaborated here.

[0092] As can be seen from the above, the sample rack to be unloaded first can be determined by the remaining measurement mode information of the samples on at least one sample rack in each unloading area. For example, the sample rack to be unloaded first can be determined by the remaining measurement mode information of the samples on all the sample racks in the unloading area, or can be determined by the remaining measurement mode information of the samples on the outermost sample rack in the unloading area, or can be determined by combining the remaining measurement mode information of the samples on the outermost sample rack and the remaining measurement mode information of the samples on the inner sample rack in the unloading area.

[0093] In another embodiment of the present invention, the preset rule is related to the number of sample racks or samples stored in the unloading area of the sample analyzer and the remaining measurement mode of the samples. For example, when the control device determines the sample rack to be unloaded first according to the preset rule: the remaining detection mode information of the samples on at least one sample rack, especially the outermost sample rack, stored on the first unloading buffer and the second unloading buffer is obtained respectively, and the remaining detection mode information includes at least one of the number of remaining detection modes, the priority of the remaining detection modes, and the test duration of the remaining detection modes, where the remaining detection mode indicates that the sample needs to be further detected; if the number of sample racks or samples stored in the first unloading buffer and the second unloading buffer is the same, the sample rack to be unloaded first is determined according to the remaining detection mode information of the first unloading buffer and the second unloading buffer. For the specific method of determining the sample rack to be unloaded first according to the remaining detection mode information, reference can be made to the above description and will not be elaborated here.

[0094] This embodiment comprehensively considers the number of sample racks or samples in the unloading buffer and the remaining detection mode of the samples on the sample racks, especially the remaining detection mode of the samples on the outermost sample rack, to determine the unloading buffer to be unloaded first, and then determine the sample rack to be unloaded first, so as to make full use of the detection ability of the subsequent sample analyzer, reduce the residence time of the sample rack in the sample analysis system, help reduce the total number of sample racks or samples in the sample analysis system, and improve the efficiency of the sample analysis system.

[0095] In another embodiment of the present invention, the preset rule is related to the operating state of the unloading destination of the outermost sample rack on the unloading area. For example, when the control device is configured to determine to unload the sample rack first according to the preset rule:

[0096] Respectively obtain the remaining detection mode information of the samples on the outermost sample rack stored on the first unloading buffer area and the second unloading buffer area;

[0097] Respectively obtain the unloading destinations of the outermost sample racks on the first unloading buffer area and the second unloading buffer area according to the remaining detection mode information, and obtain the operating state of the unloading destination;

[0098] Determine the sample rack to be unloaded first according to the operating state of the unloading destination.

[0099] In one embodiment, the sample analyzer system further includes a third sample analyzer, the control device is electrically connected to the third sample analyzer, the third sample analyzer is used to detect samples with corresponding remaining detection modes, and the control device determines the sample rack to be unloaded first according to the preset rule, including:

[0100] Obtain the operating state of the third sample analyzer, and the operating state of the third sample analyzer includes receiving scheduling and not accepting scheduling;

[0101] Obtain the remaining detection mode information of the samples on the outermost sample rack stored in the unloading buffer area, and the remaining detection mode information includes the remaining devices to be detected;

[0102] If the remaining device to be detected of the samples on the outermost sample rack in one of the unloading buffer areas is the third sample analyzer, and the operating state of the third sample analyzer is not to receive scheduling, then use the outermost sample rack in the other unloading buffer area as the sample rack to be unloaded first.

[0103] Some devices in the sample analysis system may take a long time to detect a single sample, so they may not be able to accept more sample racks and samples within a certain period of time. At this time, the operating state of this device is "not receiving scheduling"; or when the device fails, the operating state is also "not receiving scheduling". When the device can accept sample racks or samples, its state can become "accepting scheduling".

[0104] For example, a certain device can only detect one sample rack at a time, and its loading buffer area can store up to four sample racks at most. When there is one sample rack inside the device and four sample racks in the loading buffer area, the state of the device is "not receiving scheduling".

[0105] For devices that "do not accept scheduling", if more sample racks or samples are sent, these samples can only pile up on the transfer channel, causing a "blockage" on the transfer channel.

[0106] To avoid this situation, if the remaining devices to be tested for the samples on the outermost sample rack in the unloading buffer of the sample analyzer are devices that "do not accept scheduling", then first let the sample racks in other unloading buffers enter the transfer channel, thereby avoiding blockage of the transfer channel and improving the efficiency of the sample analysis system.

[0107] In another embodiment of the present invention, the preset rule is related to the sample racks to be tested of the first sample analyzer and the second sample analyzer.

[0108] In one embodiment, as Figure 3 shown, Figure 3 shown is a schematic diagram of the sample analysis system according to an embodiment of the present invention. Figure 3 Among them, Figure 1 and Figure 2 function units with the same reference numerals have the same and similar functions. The first feeding mechanism further includes a first loading buffer located between the first feeding channel 140 and the transfer channel 130

[0109] and a first loading mechanism (not shown). The first loading buffer is configured to store at least one sample rack to be tested, and the first loading mechanism is configured to transfer the sample rack stored on the first loading buffer to the first feeding channel 140. The second feeding mechanism further includes a second loading buffer 320 located between the second feeding channel 150 and the transfer channel 130 and a second loading mechanism (not shown). The second loading buffer is configured to store at least one sample rack to be tested, and the second loading mechanism is configured to transfer the sample rack stored on the second loading buffer 320 to the second feeding channel 150.

[0110] Among them, the control device determines to unload the sample rack first according to the preset rule, including: respectively obtaining the number of sample racks or samples on the first loading buffer and / or the first feeding channel and the number of sample racks or samples on the second loading buffer and / or the second feeding channel; taking the outermost sample rack of the unloading buffer corresponding to the loading buffer and / or the feeding channel with more sample racks or samples as the sample rack to be unloaded first.

[0111] In this embodiment, by counting the number of sample racks / samples in the loading buffer or / and the feeding channel, this number represents the deceleration weight caused by the instrument stop. When there are sample racks to be unloaded in the unloading areas of multiple sample analyzers, compare the deceleration weights before analysis, and preferentially schedule the sample racks in the unloading area with a larger weight.

[0112] In one embodiment, the first unloading buffer and / or the second unloading buffer are configured to store a plurality of sample racks.

[0113] In one embodiment, as Figure 4 shown, is a schematic structural diagram of a control device provided by an embodiment of the present invention. The control device 30 at least includes: a processing component 31, a RAM 112, a ROM 113, a communication interface 34, a memory 36, and an I / O interface 35. Among them, the processing component 31, the RAM 32, the ROM 33, the communication interface 34, the memory 36, and the I / O interface 35 communicate through a bus 37.

[0114] The processing component can be a CPU, a GPU, or other chips with computing capabilities.

[0115] The memory 36 stores various computer programs for the processor component 31 to execute, such as an operating system and application programs, and data required to execute the computer programs. In addition, during the sample detection process, any data that needs to be locally stored can be stored in the memory 36.

[0116] The I / O interface 35 is composed of serial interfaces such as USB, IEEE1394, or RS-232C, parallel interfaces such as SCSI, IDE, or IEEE1284, and analog signal interfaces composed of D / A converters and A / D converters. An input device composed of a keyboard, a mouse, a touch screen, or other control buttons is connected to the I / O interface 35, and the user can directly input data to the control device 30 using the input device. In addition, a display with a display function, such as a liquid crystal display, a touch screen, an LED display, etc., can also be connected to the I / O interface 35. The control device 30 can output the processed data as image display data to the display for display, such as analysis data, instrument operating parameters, etc.

[0117] The communication interface 34 can be an interface of any currently known communication protocol. The communication interface 34 communicates with the outside world through a network. The control device 30 can transmit data to any device connected through the network through the communication interface 34 according to a certain communication protocol.

[0118] Corresponding to the above sample analysis system, an embodiment of the present invention also provides a sample analysis method. Figure 5 Shown is a flowchart of the sample analysis method according to an embodiment of the present invention. As Figure 5 shown, the method includes:
