Description

[0001] This application is a divisional application of the invention patent application "Sample Analysis Detector and Cascade Sample Processing Device" with the application date of November 20, 2023 and the application number of 202311551079.2. Technical Field

[0002] The present invention relates to the technical field of sample processing devices, and particularly to a sample analysis detector and a cascade sample processing device. Background Art

[0003] In related technologies, in order to improve the scope of application, some sample processing instruments such as sample analyzers can be used as stand-alone machines and can also be connected to other sample processing instruments to form a cascade state, so that multiple sample processing instruments can be used in cooperation. Sample processing instruments are usually provided with a regular module and an emergency module. The regular module includes a regular sample track for transporting regular samples and a regular processing component for processing regular samples. The emergency component includes an emergency sample track for transporting emergency samples and an emergency processing component for processing emergency samples. The emergency component usually operates independently of the regular module to give priority to the processing of emergency samples to meet emergency needs. In the cascade situation, there are cases where some samples need to be processed by the next-level processing instrument, but there are many regular samples queuing in the regular sample track of the current processing instrument. After the regular samples in the regular sample track of the current processing instrument are processed, the samples that need to be processed by the next-level processing instrument can reach the next-level processing instrument. However, the emergency sample track is vacant due to the relatively small number of emergency samples, resulting in the underutilization of the processing capacity of the cascade processing device. Summary of the Invention

The emergency sample track of this sample analysis detector is no longer limited to the scheduling of emergency sample racks, and both regular sample racks and emergency sample racks can be scheduled through the emergency sample track. Therefore, the utilization rate of the emergency sample track can be improved, and further the utilization rate of the processing capacity of the sample analysis detector and the cascaded processing device including this sample analysis detector can be improved. When the emergency sample processing position of the emergency sample track of this sample analysis detector is vacated, the to-be-processed sample rack with the highest priority (this to-be-processed sample rack with the highest priority may be a regular sample rack or an emergency sample rack) can be scheduled to the emergency sample processing position through the emergency sample track for processing.

[0030] To achieve the above and other related purposes, the present invention provides a sample scheduling method for a cascade sample processing device. The cascade sample processing device includes at least a current processing instrument and a subsequent processing instrument. The current processing instrument has a regular sample track and an emergency sample track, and both the regular sample track and the emergency sample track are connected to the subsequent processing instrument.

[0036] Obtain the connection status between the current processing instrument and the subsequent processing instrument, where the connection status includes the single-machine state and the cascade state, and determine the mapping relationship between the type of the sample rack to be scheduled and the priority of the sample rack to be scheduled according to the connection status between the current processing instrument and the subsequent processing instrument.

[0037] If the connection status between the current processing instrument and the subsequent processing instrument is in the single-machine state, the emergency sample rack is mapped to a high priority, and the regular sample rack is mapped to a low priority.

[0038] Optionally, if the connection status between the current processing instrument and the subsequent processing instrument is in the cascade state, obtain the working status of the subsequent processing instrument, and determine the priority of each of the sample racks to be scheduled according to the working status;

[0042] Optionally, the load level is the ratio of the current sample injection quantity of the subsequent processing instrument to the full-load sample injection quantity of the subsequent processing instrument.

[0043] Optionally, determining the priority of each sample rack to be scheduled includes:

[0044] Obtain the action to be processed of the sample rack to be scheduled. If the processing action of the current processing instrument conforms to the action to be processed of the sample rack to be scheduled, the sample rack to be scheduled is mapped to a low priority; otherwise, the sample rack to be scheduled is mapped to a high priority.

[0045] Optionally, obtaining the action to be processed of the sample rack to be scheduled includes:

[0046] Determine the action to be processed of the sample rack to be scheduled according to the completed processing action and the list of actions to be processed in sequence,

[0047] The list of actions to be processed in sequence is obtained by arranging the pollution sensitivity degrees of the actions to be processed of the sample rack to be scheduled from high to low,

[0048] Alternatively, the list of actions to be processed in sequence is set in advance.

[0049] The present invention further provides a cascaded sample processing device for implementing the sample scheduling method of the cascaded sample processing device as described in any one of the above, including a current processing instrument and a subsequent processing instrument. The current processing instrument has a regular sample track and an emergency sample track, and both the regular sample track and the emergency sample track are communicated with the subsequent processing instrument.

[0050] Optionally, an emergency sample processing position is provided on the emergency sample track, and an emergency sample storage position is provided after the emergency sample processing position in the conveying direction of the emergency sample track.

The blocking mechanism blocks the emergency sample track to form the emergency sample storage position, and the distance between the blocking mechanism and the emergency sample processing position is greater than the size of the to-be-scheduled sample rack in the conveying direction of the emergency sample track.

[0052] In this application, the priorities of the to-be-scheduled sample racks are determined, and the to-be-scheduled sample rack with the highest priority is scheduled into the emergency sample track for circulation. In the present invention, the to-be-processed samples are scheduled according to the priorities of the to-be-processed samples. When the priority of the regular sample rack in the to-be-scheduled sample rack is higher than that of the emergency sample rack, the regular sample rack can also enter the emergency sample track for scheduling, and then be processed by the emergency component of the current processing instrument, or enter the subsequent processing instrument through the emergency sample track, instead of queuing in the regular sample track, which improves the comprehensive utilization rate of the emergency sample track, makes full use of the processing capacity of the cascade processing device, and thus improves the comprehensive sample processing efficiency of the cascade processing device.

[0068] Please refer to Figure 1, this embodiment provides a sample scheduling method for a cascaded sample processing device. The cascaded sample processing device includes at least a current processing instrument and a subsequent processing instrument. The current processing instrument has a regular sample track and an emergency sample track, and both the regular sample track and the emergency sample track are connected to the subsequent processing instrument.

[0069] The sample scheduling method includes the following steps:

[0070] S10: Obtain the types of each sample rack to be scheduled. The types of the sample racks to be scheduled include regular sample racks and emergency sample racks;

[0071] S20: Determine the priority of each sample rack to be scheduled;

[0072] S30: Schedule the sample rack to be scheduled with the highest priority to the emergency sample track for circulation.

[0073] As Figure 2 shown, in some embodiments, in step S20, that is, in the step of determining the priority of each sample rack to be scheduled, according to the type of the sample rack to be scheduled and the mapping relationship between the type of the sample rack to be scheduled and the priority of the sample rack to be scheduled, determine the priority of each sample rack to be scheduled respectively.

[0074] Specifically, in step S20, it includes the following sub-steps:

[0075] S21: Obtain the connection status between the current processing instrument and the subsequent processing instrument. The connection status includes a single-machine status and a cascaded status. Determine the mapping relationship between the type of the sample rack to be scheduled and the priority of the sample rack to be scheduled according to the connection status between the current processing instrument and the subsequent processing instrument.

[0076] Specifically, determine whether the connection status between the current processing instrument and the subsequent processing instrument is a cascaded status.

[0077] If the connection status between the current processing instrument and the subsequent processing instrument is a non-cascaded status, that is, a single-machine status, it can be determined that the emergency sample rack is mapped to a high priority, and the regular sample rack is mapped to a low priority. When the connection status between the current processing instrument and the subsequent processing instrument is a single-machine status, each processing instrument processes its own sample rack respectively, and there is no need to schedule the sample rack between the processing instruments. At this time, the regular samples are circulated through the regular sample track, and the emergency sample rack is circulated through the emergency sample track.

[0078] In some embodiments, if in step S21, the connection status between the current processing instrument and the subsequent processing instrument is a cascaded status, then in step S20, that is, in the step of determining the priority of each sample rack to be scheduled, it further includes the following sub-steps:

[0079] S22: Obtain the working state of the subsequent processing instrument, and determine the priority of each sample rack to be scheduled according to the working state. Specifically, determine whether the subsequent processing instrument is in the working state. If the subsequent processing instrument is in the non-working state, the emergency sample rack is mapped to a high priority, and the regular sample rack is mapped to a low priority.

[0080] In some embodiments, if in step S22, the subsequent processing instrument is in the working state, then in step S20, that is, in the step of determining the priority of each sample rack to be scheduled, the following sub-steps are further included:

[0081] S23: Obtain the load level of the subsequent processing instrument, and determine the mapping relationship between the type of the sample rack to be scheduled and the priority of the sample rack to be scheduled according to the comparison result between the load level and the preset load threshold.

[0082] If the load level is lower than the preset load threshold, the regular sample rack is mapped to a high priority, and the emergency sample rack is mapped to a low priority.

[0083] If the load level is higher than or equal to the preset load threshold, the regular sample rack is mapped to a low priority, and the emergency sample rack is mapped to a high priority.

[0084] In this embodiment, the load level is the ratio of the current sample injection quantity of the subsequent processing instrument to the full-load sample injection quantity of the subsequent processing instrument. The higher the ratio of the current sample injection quantity of the subsequent processing instrument to the full-load sample injection quantity of the subsequent processing instrument, the higher the load level of the subsequent processing instrument. In this embodiment, when the load level of the subsequent processing instrument reaches or exceeds the preset load threshold, the priority value of the regular sample rack is reduced, and the number of regular sample racks entering the post-processing instrument through the emergency sample track is reduced, which is beneficial to alleviating the load of the subsequent processing instrument and avoiding the overcrowding of a single processing instrument and reducing the processing efficiency of the entire cascade processing device. The higher the preset load threshold, the more sample racks enter the single processing instrument at the same time. At the same time, the probability of reducing the overall processing efficiency of the cascade processing device due to the congestion of the single processing instrument is also greater. Therefore, in actual situations, the preset load threshold needs to be reasonably set to avoid too few sample racks entering the single processing instrument at the same time, wasting the processing capacity of the processing instrument, and at the same time avoiding the congestion of the single processing instrument and reducing the processing efficiency of the entire cascade processing device.

[0085] In other embodiments, in step S20, that is, in the step of determining the priority of each sample rack to be scheduled, according to the mapping relationship among the processing actions to be performed on the sample rack to be scheduled, the processing actions of the current processing instrument, and the priority of the sample rack to be scheduled, the priority of the sample rack to be scheduled is determined.

[0086] Such as Figure 3As shown, step S20 includes the following sub-steps:

[0087] S24: Obtain the to-be-processed actions of the sample rack to be scheduled,

[0088] S25: Compare the to-be-processed actions of the sample rack to be scheduled with the processing actions of the current processing instrument.

[0089] If the to-be-processed actions of the sample rack to be scheduled match the processing actions of the current processing instrument, the sample rack to be scheduled is mapped to a low priority. Conversely, if the processing actions of the current processing instrument do not match the to-be-processed actions of the sample rack to be scheduled, the sample rack to be scheduled is mapped to a high priority.

[0090] The to-be-processed actions of the sample rack to be scheduled are also the processing actions that the sample rack to be scheduled is about to perform. The processing actions of the current processing instrument matching the to-be-processed actions of the sample rack to be scheduled means that the sample rack to be scheduled can be processed by the current processing instrument, without the need to schedule the sample rack to be scheduled to other devices, improving the overall processing efficiency of the device.

[0091] Specifically, in some embodiments, obtain the completed processing actions of the sample rack to be scheduled, and determine the to-be-processed actions of the sample rack to be scheduled according to the completed processing actions and the to-be-processed action sequence list.

[0092] Among them, in some embodiments, the to-be-processed action sequence list can be obtained by arranging the to-be-processed actions of each sample rack to be scheduled from high to low according to the pollution sensitivity degree. The higher the pollution sensitivity degree, the greater the impact of pollution on the sample processing effect or detection result. Placing the to-be-processed actions with high pollution sensitivity degree at the front of the to-be-processed action sequence list can reduce the impact of pollution on the processing result and improve the overall processing effect. For example, when an immunoassay instrument - biochemical analyzer is cascaded, the same sample is used for immunoassay and biochemical assay respectively, and immunoassay is more sensitive to pollution. Therefore, the sample should be first assigned to the immunoassay instrument and then to the biochemical analyzer.

[0093] In other embodiments, the to-be-processed action sequence list of the sample can also be obtained by being pre-set by the operator. For example, when immunoassay instruments are cascaded, the reagents stored in each immunoassay instrument are different. Therefore, different samples need to specify the corresponding immunoassay instrument according to the reagents stored in the immunoassay instrument.

[0094] Please refer to Figures 4 to 11 , this embodiment also provides a cascaded sample processing device for implementing the sample scheduling method of the cascaded sample processing device as above, including a current processing instrument and subsequent processing instruments. The current processing instrument has a regular sample track and an emergency sample track, and both the regular sample track and the emergency sample track are connected to the subsequent processing instruments.

[0095] In this embodiment, the processing instrument is a sample analysis and detection instrument, such as a chromatograph, a spectrometer, an electrophoresis instrument, etc., which is used to analyze and detect the samples in the sample rack.

[0096] In this embodiment, an emergency sample processing position is provided on the emergency sample track. In the conveying direction of the emergency sample track, an emergency sample storage position is provided after the emergency sample processing position. The emergency sample processing position and the emergency sample storage position can both store the emergency sample rack 8. When the emergency sample rack 8 on the emergency sample track 2 is not received by the subsequent processing instrument after being processed, the processed emergency sample rack 8 can be moved to the emergency sample storage position for temporary storage, waiting for the subsequent processing instrument to receive it. After the processed emergency sample rack 8 is moved to the emergency sample storage position, the emergency sample processing position becomes vacant, and the to-be-processed sample rack with the highest priority can be scheduled to the emergency sample processing position for processing, so that the next batch of to-be-processed sample racks can be scheduled, without waiting for the subsequent processing instrument to receive the processed emergency sample rack 8, thus improving the overall processing efficiency of the cascaded sample processing device.

[0097] In this embodiment, in the conveying direction of the emergency sample track, a blocking mechanism 5 is provided after the sample processing position. The blocking mechanism 5 blocks the emergency sample track to form an emergency sample storage position. The distance between the blocking mechanism 5 and the emergency sample processing position is greater than the size of the to-be-scheduled sample rack in the conveying direction of the emergency sample track, so that the emergency sample storage position can meet the requirement of storing the emergency sample rack 8.

[0098] Specifically, as Figures 4 to 11 shown, in this embodiment, the end outlet of the emergency sample track 2 and the end outlet of the regular sample track 1 are arranged in sequence. The processing instrument has a rail-changing component 10, and the rail-changing component 10 is arranged corresponding to the end outlets of the emergency sample track 2 and the regular sample track 1. The rail-changing component 10 includes a rail-changing track 4, a slide rail 9 and a blocking mechanism 5. The slide rail 9 is arranged in sequence along the connection line direction of the end outlet of the emergency sample track 2 and the end outlet of the regular sample track 1. The rail-changing track 4 slides on the slide rail 9, so that it can be aligned with the emergency sample track 2 and the regular sample track 1 in sequence. As Figures 5 to 6 and Figure 9 shown, in this embodiment, the emergency sample track 2 and the regular sample track 1 are arranged in parallel and the end outlets are aligned. Figure 9The direction pointed by the arrow in the figure is the conveying direction of the emergency sample track 2 and the regular sample track 1. The extending direction of the slide rail 9 is perpendicular to the extending direction of the emergency sample track 2 and the extending direction of the regular sample track 1 respectively. One end of the transfer track 4 is used to align with the emergency sample track 2 and the regular sample track 1, so as to receive the sample racks of the emergency sample track 2 and the regular sample track 1. The other end of the transfer track 4 is used to align with the regular sample track 1 or the emergency sample track 2 of the subsequent processing instrument, so as to convey the sample rack therein to the regular sample track 1 or the emergency sample track 2 of the subsequent processing instrument.

[0099] As Figure 7 and Figure 8 shown, in this embodiment, the blocking mechanism 5 is slidably arranged on the slide rail 9. As Figure 7 shown, when the blocking mechanism 5 deviates from the emergency sample track 2, the blocking mechanism 5 is in the release position, and at this time, the sample rack in the emergency sample track 2 can pass through. As Figure 8 shown, when the blocking mechanism 5 aligns with the emergency sample track 2, the blocking mechanism 5 is in the blocking position, so as to block the sample rack in the emergency sample track 2 and make the sample rack stay in the emergency sample storage position. In this embodiment, the blocking mechanism 5 is a blocking piece, and the blocking piece has a simple structure and a light weight, which is suitable for industrial applications.

[0100] As Figures 4 to 9 shown, in this embodiment, the processing device further includes a return track 3. The inlet of the return track 3 is also arranged in the extending direction of the slide rail 9. When the transfer track 4 slides on the slide rail 9, it can also align with the return track 3, so as to return the sample rack of the current processing instrument. A return transition track 6 is slidably arranged on the slide rail 9. One end of the return transition track 6 can align with the return track 3, and the other end aligns with the subsequent processing instrument, so as to receive the sample rack returned by the subsequent instrument. The conveying direction of the return track 3 is opposite to the conveying directions of the emergency sample track 2 and the regular sample track 1, so as to return the sample rack to the previous level of the current processing instrument. The previous level of the current processing instrument can also be other processing instruments or the storage device of the sample rack.

[0101] As Figure 10 and Figure 11As shown in the figure, in this embodiment, a drive motor is provided in the orbit-changing assembly 10 to drive the orbit-changing track 4 to move. In this embodiment, the orbit-changing track 4 is arranged between the return transition track 6 and the blocking mechanism 5. The end outlet of the conventional sample track 1 is arranged between the head-end inlet of the return track 3 and the end outlet of the emergency sample track 2. A first return spring 11 is connected to the blocking mechanism 5, and a second return spring 12 is connected to the return transition track 6. When the orbit-changing track 4 is aligned with the conventional sample track 1, that is, in the initial state, the return transition track 6 is aligned with the return track 3, and the blocking mechanism 5 is aligned with and blocks the emergency sample track 2. When the orbit-changing track 4 moves towards the emergency sample track 2, it pushes the blocking mechanism 5 and stretches the first return spring 11, so that the blocking mechanism 5 is in the release position until the orbit-changing track 4 is aligned with the emergency sample track 2, and the emergency sample track 2 is opened. At this time, the sample rack in the emergency sample track 2 can enter the orbit-changing track 4.

[0102] When the orbit-changing track 4 moves towards the return track 3, the first return spring 11 drives the blocking mechanism 5 to reset, so that the blocking mechanism 5 returns to the blocking position to block the emergency sample track 2. The orbit-changing track 4 continues to move towards the return track 3, pushing the return transition track 6 and stretching the second return spring 12 until the orbit-changing track 4 is aligned with the return track 3. At this time, the sample rack in the orbit-changing track 4 can enter the return track 3. When the orbit-changing track 4 returns to the initial position, that is, when it is aligned with the conventional sample track 1, the return transition track 6 is reset under the drive of the second return spring 12 and is aligned with the return track 3.

[0103] In summary, in a sample analysis detector and a cascaded sample processing device according to this embodiment, since the priorities of each of the to-be-scheduled sample racks are determined respectively according to the type of the to-be-scheduled sample rack and the mapping relationship between the type of the to-be-scheduled sample rack and the priority of the to-be-scheduled sample rack; the to-be-scheduled sample racks include conventional sample racks and emergency sample racks; the to-be-scheduled sample rack with the highest priority is scheduled into the emergency sample track for circulation. In the present invention, the to-be-processed samples are scheduled according to the priorities of the to-be-processed samples. When the priority of the conventional sample rack in the to-be-scheduled sample rack is higher than that of the emergency sample rack, the conventional sample rack can also enter the emergency sample track for scheduling, and then be processed in the emergency component of the current processing instrument, or enter the subsequent processing instrument through the emergency sample track, instead of queuing in the conventional sample track, improving the comprehensive utilization rate of the emergency sample track, making full use of the processing capacity of the cascaded processing device, and thus improving the comprehensive sample processing efficiency of the cascaded processing device.
