Description

Technical Field

[0001] The present invention belongs to the technical field of biochemical analysis and immunoassay equipment, and more specifically, relates to a sample injection scheduling method of a sample analysis system and a sample analysis system. Background Art

[0002] In the related art, a type of sample analysis system usually uses multiple sample analysis modules online, and connects each sample analysis module in series through a track transmission module to form a track-type assembly line detection system. The track transmission module includes a sampling track and a recovery track. The sampling track is used to transport the sample rack to be tested to one or more target sample analysis modules for sampling. The sample rack that has completed sampling is transferred to the recovery track and is transmitted to the end of the recovery track to be taken away by the sampler.

[0003] However, although the sampling scheduling method based on the above-mentioned track transmission module can better realize the sample delivery of a single sample rack to be tested to multiple sample analysis modules, in the scenario where multiple sample racks to be tested are delivered to multiple sample analysis modules, when it is necessary to handle the scheduling task of multiple sample racks to be tested between different sample analysis modules, one sampling track carries the dual functions of sampling and sample rack scheduling, which is bound to lead to low scheduling efficiency of sample racks between different sample analysis modules, thereby affecting the analysis and detection efficiency of the entire sample analysis system. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the related art that the sampling scheduling mode of the sample analysis system affects the analysis and detection efficiency of the system.

[0005] In order to achieve the above objective, the present invention provides a sample injection scheduling method of a sample analysis system and a sample analysis system.

[0006] According to a first aspect of the present invention, there is provided a sampling scheduling method of a sample analysis system, wherein the sample analysis system comprises a sample analysis module A and a track transmission module A disposed on a sampling side thereof, and a sample analysis module B and a track transmission module B disposed on a sampling side thereof, wherein the sample analysis module A and the sample analysis module B are arranged side by side so that the track transmission module A and the track transmission module B are docked;

[0007] The track transmission module A comprises a sampling track A, a scheduling track A and a recovery track A which are parallel to each other and successively away from the sample analysis module A, and a terminal track change unit A;

[0008] The track transmission module B includes a sampling track B, a scheduling track B and a recovery track B which are parallel to each other and successively away from the sample analysis module B, and a terminal track change unit B;

[0009] The injection scheduling method comprises:

[0010] Obtaining all the test item information corresponding to each test sample rack;

[0011] According to the detection item information supported by the sample analysis module A and the sample analysis module B respectively, each sample rack to be tested is divided into a sample rack A that is only sent to the sample analysis module A for sampling, a sample rack B that is only sent to the sample analysis module B for sampling, and a sample rack AB that is first sent to the sample analysis module A for sampling and then sent to the sample analysis module B for sampling;

[0012] Sample rack A and sample rack AB are defined as first-type sample racks, and sample rack B is defined as second-type sample rack;

[0013] The first type of sample rack and the second type of sample rack are sampled alternately, wherein the sample rack A for sampling passes through the sampling track A, the terminal track changing unit A and the recovery track A in sequence, the sample rack B for sampling passes through the scheduling track A, the terminal track changing unit A, the sampling track B, the terminal track changing unit B, the recovery track B, the terminal track changing unit A and the recovery track A in sequence, and the sample rack AB passes through the sampling track A, the terminal track changing unit A, the sampling track B, the terminal track changing unit B, the recovery track B, the terminal track changing unit A and the recovery track A in sequence.

[0014] Optionally, the dividing of each sample rack to be tested into a sample rack A sent only to the sample analysis module A for sampling, a sample rack B sent only to the sample analysis module B for sampling, and a sample rack AB sent first to the sample analysis module A for sampling and then to the sample analysis module B for sampling according to the detection item information supported by each of the sample analysis module A and the sample analysis module B comprises:

[0015] If all the items to be tested corresponding to a sample rack to be tested are only supported by sample analysis module A, then the sample rack to be tested is divided into sample rack A;

[0016] If all the items to be tested corresponding to a sample rack to be tested are only supported by sample analysis module B, then the sample rack to be tested is divided into sample rack B;

[0017] If a portion of the items to be tested corresponding to a sample rack to be tested is only supported by sample analysis module A and another portion of the items to be tested is only supported by sample analysis module B, the sample rack to be tested is divided into sample racks AB;

[0018] If all the items to be tested corresponding to a sample rack to be tested are supported by both sample analysis module A and sample analysis module B, the target sample analysis module is determined according to a predetermined target sample analysis module determination strategy. If the target sample analysis module is sample analysis module A, the sample rack to be tested is divided into sample rack A. If the target sample analysis module is sample analysis module B, the sample rack to be tested is divided into sample rack B.

[0019] If a part of the test items corresponding to a sample rack to be tested is only supported by sample analysis module A and another part of the test items is supported by both sample analysis module A and sample analysis module B, the target sample analysis module is determined according to the target sample analysis module determination strategy. If the target sample analysis module is sample analysis module A, the sample rack to be tested is divided into sample rack A. If the target sample analysis module is sample analysis module B, the sample rack to be tested is divided into sample rack AB.

[0020] If a part of the test items corresponding to a sample rack to be tested is only supported by sample analysis module B and another part of the test items is supported by both sample analysis module A and sample analysis module B, the target sample analysis module is determined according to the target sample analysis module determination strategy. If the target sample analysis module is sample analysis module A, the sample rack to be tested is divided into sample rack AB. If the target sample analysis module is sample analysis module B, the sample rack to be tested is divided into sample rack B.

[0021] The target sample analysis module determines the strategy including:

[0022] Compare the remaining validity periods of the reagents corresponding to the corresponding test items of the sample analysis module A and the sample analysis module B, and use the sample analysis module with the shorter remaining validity period as the target sample analysis module;

[0023] If the remaining validity periods of the reagents are the same, the number of currently remaining test items of sample analysis module A and sample analysis module B is compared, and the sample analysis module with the smaller number of currently remaining tests is used as the target sample analysis module;

[0024] If the number of currently remaining test items is the same, then the current remaining test item times of sample analysis module A and sample analysis module B are compared, and the sample analysis module with the shorter current remaining test item time is used as the target sample analysis module.

[0025] According to a second aspect of the present invention, there is provided a sample analysis system, the sample analysis system comprising a controller, the controller comprising a processing module and a storage module, the processing module implementing any of the above-mentioned sample analysis system injection scheduling methods when executing a computer program stored in the storage module.

[0026] The beneficial effects of the present invention are:

[0027] The sampling scheduling method of the sample analysis system of the present invention, on the one hand, configures an additional scheduling track for the track transmission module corresponding to each sample analysis module on the basis of the original sampling track and the recovery track. After multiple sample analysis modules are used online, the scheduling track is used to realize the scheduling of the sample rack to be tested between the multiple sample analysis modules, and the resources of the sampling track are no longer occupied. When the sample rack to be tested realizes the sampling through the sampling track, it does not affect the transfer scheduling of other sample racks to be tested in the multiple sample analysis modules, thereby realizing that the sampling and sample rack scheduling are completed by independent tracks respectively, thereby achieving the purpose of improving the scheduling efficiency of the sample rack and the analysis and detection efficiency of the sample analysis system. On the other hand, the present invention divides the sample racks to be tested into a first type of sample rack and a second type of sample rack. The first type of sample rack is a sample rack that needs to use the sampling tracks corresponding to other sample analysis modules to achieve sampling, and the second type of sample rack is a sample rack that can achieve sampling relative to the target sample analysis module only through the scheduling tracks corresponding to other sample analysis modules and the sampling tracks corresponding to the target sample analysis module; by alternately sampling the first type of sample rack and the second type of sample rack, the resources of the sampling track and the scheduling track can be used more balanced, reducing the occurrence of sample racks waiting for loading on the corresponding tracks, thereby improving the transportation efficiency and detection efficiency of the sample racks.

[0028] The sample analysis system of the present invention and the sampling scheduling method of the sample analysis system belong to a general inventive concept, and have at least the same beneficial effects as the sampling scheduling method of the sample analysis system, and the beneficial effects are not repeated here.

[0044] The sample analysis system further includes a sample chamber module 300, which includes a sample chamber base and a sample feeder track 301 disposed on the sample chamber base, four tray units 303 and three emergency position units 305, and a sample feeder 304 configured to be able to reciprocate on the sample feeder track 301, and a barcode scanner is disposed on the sample feeder 304;

[0045] Each tray unit 303 can provide 10 sample rack positions, each sample rack position can accommodate one sample rack 302, and each sample rack 302 has 5 accommodating positions; each emergency position unit can provide 1 sample rack position.

[0046] Figure 2 The flowchart of the implementation of the sampling scheduling method of the sample analysis system according to the embodiment of the present invention is shown. Figure 2 The sampling scheduling method of the sample analysis system of the embodiment of the present invention comprises the following steps:

[0047] Step S100, obtaining all the test item information corresponding to each test sample rack;

[0048] Step S200: According to the detection item information supported by the sample analysis module A and the sample analysis module B, each sample rack to be tested is divided into a sample rack A that is only sent to the sample analysis module A for sampling, a sample rack B that is only sent to the sample analysis module B for sampling, and a sample rack AB that is first sent to the sample analysis module A for sampling and then sent to the sample analysis module B for sampling;

[0049] Step S300, defining sample rack A and sample rack AB as first-type sample racks, and defining sample rack B as second-type sample rack;

[0050] Step S400, alternately injecting samples into the first type sample rack and the second type sample rack, wherein the injected sample rack A passes through the sampling track A, the terminal track changing unit A and the recovery track A in sequence, the injected sample rack B passes through the scheduling track A, the terminal track changing unit A, the sampling track B, the terminal track changing unit B, the recovery track B, the terminal track changing unit A and the recovery track A in sequence, and the injected sample rack AB passes through the sampling track A, the terminal track changing unit A, the sampling track B, the terminal track changing unit B, the recovery track B, the terminal track changing unit A and the recovery track A in sequence.

[0051] Specifically, in the embodiment of the present invention, before executing step S100, the sample rack to be tested needs to be placed in the sample bin, specifically: the sample rack to be tested is distinguished by different color types, including four types of conventional sample racks, emergency sample racks, calibration sample racks and quality control sample racks. The emergency sample rack needs to be placed on 3 emergency sample racks, and other types of sample racks are placed on 40 conventional sample racks. When the sample rack to be tested is placed on the sample rack, the sample rack status sensor set on the sample rack will feed back the corresponding status to the system controller after detecting the existence of the sample rack. The system controller controls the sample feeder 304 to pull out the target sample rack and scan the sample barcode information of the sample rack through the barcode scanner. Based on the sample barcode information, all the information of the items to be tested corresponding to the sample rack can be obtained, that is, the information of the items to be tested corresponding to each sample tube carried by the sample rack. The barcode scanner uploads the obtained information of all the items to be tested corresponding to the sample rack to the system controller.

[0052] Furthermore, in the embodiment of the present invention, step S200 is specifically as follows:

[0053] After obtaining all the information of the items to be tested corresponding to the sample rack to be tested, it is compared one by one with the information of the test items supported by the sample analysis module A and the sample analysis module B respectively, and the following comparison results will be obtained:

[0054] If all the items to be tested corresponding to the sample rack to be tested are only supported by the sample analysis module A, then the sample rack to be tested is divided into sample rack A, that is, the sample rack to be tested is only sent to the sample analysis module A for sampling;

[0055] If all the items to be tested corresponding to the sample rack to be tested are only supported by the sample analysis module B, the sample rack to be tested is divided into sample rack B, that is, the sample rack to be tested is only sent to the sample analysis module B for sampling;

[0056] If a portion of the items to be tested corresponding to the sample rack to be tested is only supported by the sample analysis module A and another portion of the items to be tested is only supported by the sample analysis module B, the sample rack to be tested is divided into sample racks AB, that is, the sample rack is first sent to the sample analysis module A for sampling and then sent to the sample analysis module B for sampling;

[0057] If all the items to be tested corresponding to the sample rack to be tested are supported by both sample analysis module A and sample analysis module B, the target sample analysis module is determined according to a predetermined target sample analysis module determination strategy. If the target sample analysis module is sample analysis module A, the sample rack to be tested is divided into sample rack A. If the target sample analysis module is sample analysis module B, the sample rack to be tested is divided into sample rack B.

[0058] If a part of the test items corresponding to the sample rack to be tested is only supported by the sample analysis module A and another part of the test items is supported by both the sample analysis module A and the sample analysis module B, the target sample analysis module is determined according to the target sample analysis module determination strategy. If the target sample analysis module is the sample analysis module A, the sample rack to be tested is divided into sample rack A. If the target sample analysis module is the sample analysis module B, the sample rack to be tested is divided into sample rack AB.

[0059] If a part of the test items corresponding to the sample rack to be tested is only supported by the sample analysis module B and another part of the test items is supported by both the sample analysis module A and the sample analysis module B, the target sample analysis module is determined according to the target sample analysis module determination strategy. If the target sample analysis module is the sample analysis module A, the sample rack to be tested is divided into sample rack AB. If the target sample analysis module is the sample analysis module B, the sample rack to be tested is divided into sample rack B.

[0060] The target sample analysis module determines the strategy including:

[0061] Compare the remaining validity periods of the reagents corresponding to the corresponding test items of the sample analysis module A and the sample analysis module B, and use the sample analysis module with the shorter remaining validity period as the target sample analysis module;

[0062] If the remaining validity periods of the reagents are the same, the number of currently remaining test items of sample analysis module A and sample analysis module B is compared, and the sample analysis module with the smaller number of currently remaining tests is used as the target sample analysis module;

[0063] If the number of currently remaining test items is the same, then the current remaining test item times of sample analysis module A and sample analysis module B are compared, and the sample analysis module with the shorter current remaining test item time is used as the target sample analysis module.

[0064] Specifically, in the embodiment of the present invention, after determining that each sample rack to be tested is sample rack A, sample rack B or sample rack AB, sample rack A and sample rack AB are defined as first-class sample racks, and sample rack B is defined as second-class sample racks. Among them, the first-class sample racks are sample racks that require the use of sampling track A to achieve sampling, and the second-class sample racks are sample racks that only require the use of scheduling track A and sampling track B to complete sampling. By alternately sampling the first-class sample racks and the second-class sample racks, the resources of the sampling track and the scheduling track can be used more balanced, reducing the occurrence of sample racks waiting for loading on the corresponding tracks, thereby improving the transportation efficiency and detection efficiency of the sample racks.

[0065] Specifically, the sampling scheduling method of the sample analysis system of the embodiment of the present invention mainly involves the following sample delivery scenarios of a single or multiple sample racks A, a single or multiple sample racks B, a single or multiple sample racks AB, and a mixed sample delivery scenario in actual application;

[0066] For the sample delivery scenario of a single or multiple sample racks A, that is, a single or multiple sample racks to be tested need to be sent to the sample analysis module A for sampling. By setting a buffer position before sampling on the sampling track A, it can meet the continuity of the sample rack during the transmission process, that is, continuous sample addition can be achieved, thereby improving the transmission efficiency and detection efficiency of the sample rack. The specific scheduling process is as follows: Figure 3 shown.

[0067] For the sample delivery scenario of a single or multiple sample racks B, that is, a single or multiple sample racks to be tested need to be sent to the sample analysis module B for sampling. By adding a cache bit design on the scheduling track A, it can complete the scheduling task of going to the sample analysis module B alone from the scheduling track A without occupying the sampling track A. This greatly improves the throughput of the sample rack, thereby improving the transportation efficiency and detection efficiency of the sample rack. The specific scheduling process is as follows: Figure 4 shown.

[0068] For the sample delivery scenario of a single or multiple sample racks AB, that is, it is necessary to send a single or multiple sample racks to be tested to the sample analysis module A for sampling and then to the sample analysis module B for sampling, the end track change unit A of the track transmission module A can meet the transmission process of the sample rack from the sample analysis module A to the sample analysis module B, so as to meet the online effect and improve the sample detection throughput. The specific scheduling process is as follows: Figure 5 shown.

[0069] Sample rack scheduling in mixed sample delivery scenarios, by adding a post-sampling cache position at the end of sampling track A, to meet the sample rack scheduling tasks in complex situations. Mixed sample delivery scenarios specifically include: multiple sample racks to be tested include sample rack A and sample rack AB, multiple sample racks to be tested include sample rack B and sample rack AB, multiple sample racks to be tested include sample rack A and sample rack B, multiple sample racks to be tested include sample rack A, sample rack AB and sample rack B. By designing an efficient sample rack scheduling process, the sample rack transportation efficiency in various complex mixed modes can be met. The specific scheduling process is as follows Figure 6 shown.

[0070] The sampling scheduling method of the sample analysis system of the embodiment of the present invention provides a simple, efficient, safe, assembly-line, and automated sample transportation mode, which can greatly improve the efficiency of the entire sample analysis, greatly reduce human intervention, and ensure the safety and efficiency of sample analysis. The sampling track and the scheduling track are designed separately, which can greatly improve the scheduling and turnover efficiency of the sample racks between the sample analysis modules, thereby improving the sample detection efficiency of the entire online system.

[0071] Accordingly, based on the sampling scheduling method of the sample analysis system of the embodiment of the present invention, the embodiment of the present invention also proposes a sample analysis system, which includes a controller, and the controller includes a processing module and a storage module. When the processing module executes the computer program stored in the storage module, the sampling scheduling method of the sample analysis system is implemented.

[0072] Although one or more embodiments of the present invention are described above, it should be known to those skilled in the art that the present invention can be implemented in any other form without departing from its subject matter and scope. Therefore, the embodiments described above are illustrative rather than restrictive, and many modifications and substitutions are obvious to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
