The invention relates to a sample monitoring method, in particular to a method and a system for monitoring samples on a pipeline.

Background technique

With the advancement of automation control technology and analysis technology in the medical field, the application demand for testing a large number of samples and multiple indicators in the medical field is increasing. In the existing technology, sample testing has become a pipeline operation, which is completed by a set of automated testing equipment. . The dispatching mechanism of the equipment will automatically and rationally allocate each sample tube rack to each sample analyzer for analysis according to factors such as load information, inspection speed, and sample tube rack related information of each sample analyzer. The pipeline operation of sample detection increases the speed of sample detection, and the device automatically schedules the samples. When the user (such as medical staff) places the sample tube rack on the pipeline, he can wait for the pipeline to output the results and then review And submit a report, the staff does not need to participate in the detection process, which saves manpower costs to a certain extent.

However, when the user wants to know whether a specific sample has output the result, the user needs to manually refresh and query the client to know whether the sample result has come out. If the results come out, you can review the results and submit a report; if the results have not come out, the user needs to go to the assembly line to check the approximate location of the sample to see whether it is located on the loading platform or the preparation analysis area of the sample analyzer, and then according to the assembly line The number of samples and the load information of each sample analyzer are estimated based on experience how long it takes to output the analysis results. When the time for estimation is up, go to view the results.

The disadvantage of this method is that the user cannot easily know the completion time of the sample inspection, which is not conducive to the user's work arrangement; even if the user can estimate the completion time of the sample inspection based on experience, there is often a large error between the actual completion time and the actual It is when the emergency sample tube rack is inserted, analyzer failure or test interruption and other special circumstances, the completion time error estimated based on experience is greater.

In an embodiment of the present invention, a method and system for monitoring a sample on a pipeline are provided, based on the tube rack information of the sample tube rack where the sample to be monitored is located, the load information of the target analyzer, and the detection speed of the target analyzer And the scheduling path to calculate the test completion time of the sample to be monitored, and output the prompt information of the corresponding sample according to the test completion time. And the system can monitor the sample tube rack, scheduling path, and target analyzer status in real time, so that when the scheduling path conflict is found, the emergency sample is inserted, the target analyzer fails, or the test is interrupted, the system can perform real-time inspection completion of the monitored sample. Update.

In the embodiment of the present invention, a pipeline analysis system is used to monitor samples on the pipeline. Referring to FIG. 1, the pipeline analysis system 10 includes a processing terminal 11, a scheduling mechanism 12, and a detection mechanism 13.

As shown in FIG. 2, the processing terminal 11 includes a memory, a processor, and a human-machine interaction device, where the memory is used to store programs and data. The processor is used to execute the programs and processing data stored in the memory. In the embodiment of the present invention, the processor is used to obtain the tube rack information of the sample tube rack from the detection mechanism 13; Information and real-time load information are determined as the target analyzers for inspection of the unfinished items of the sample tube rack; and the scheduling path for the sample tube rack is planned according to the target analyzer currently corresponding to the sample tube rack to control the scheduling The mechanism 12 transfers the sample tube rack to the target analyzer according to the planned scheduling path for detection. In the embodiment of the present invention, the processor is also used to calculate the test completion time of the sample to be monitored, that is, how long it is before a certain sample to be monitored can complete all its tests.

The completion time of the sample test is related to many factors, and various factors are constantly changing with the changes of the situation, so the completion time of the sample test is difficult to predict. E.g:

When a pipeline analysis system is used to test a sample, the sample is usually contained in a predetermined container (for example, a test tube). A test tube is called a sample, and several samples are loaded on a sample tube rack and transferred together. Samples loaded on the same sample tube rack may be inspected for the same item or different items, so for a sample on the sample tube rack, it must be transferred to its own inspection project The target analyzer used must also be transferred to the target analyzer needed for the inspection items of other samples after the sample tube rack is transferred. Therefore, the completion time of the inspection of the sample does not completely depend on the number of its own inspection items.

In addition, the inspection completion time of the monitored sample is also related to the load of the target analyzer to be transferred. The more samples the target analyzer needs to check, that is, the greater the number of loads, the time the monitored sample waits at the target analyzer The longer. However, the load information of the target analyzer will continue to change according to the specific situation. For example, when an emergency sample is inserted, the load information of the target analyzer will change; when the target analyzer fails, the load information of the target analyzer will change; when the target When the analyzer interrupts the test due to replacement of reagents or other consumables, the load information of the target analyzer will change; when the scheduling path of other sample tube racks changes, the load information of the target analyzer may also change. This makes it difficult to predict the completion time of the monitored samples.

In the creative process of the present invention, the inventor sorted out and classified various factors that affect the completion time of the sample test, and realized the prediction of the completion time of any sample test. In a specific embodiment, the inventor believes that the inspection completion time of the sample to be monitored can be calculated based on the tube rack information of the sample tube rack where the sample to be monitored is located, the load information of the target analyzer, the inspection speed of the target analyzer and the scheduling path, and according to At the completion time of the inspection, the prompt information of the corresponding sample is output.

The human-machine interactive device includes a display and an input device. The display is used to display the prompt information of the corresponding sample output by the processor. The prompt information includes the sample inspection completion time, the audit time after the inspection is completed, the unload time, the recovery time, the report time and At least one of the current location information of the sample. The input device may be at least one of a keyboard, a mouse, a scanner, and a touch screen, and the user inputs commands, options, and / or information through the input device.

The detection mechanism 13 includes a loading platform, at least one sample analyzer, a channel, and an unloading platform. The loading platform is used to put the sample tube rack and read the identification number of the sample tube rack to obtain the tube rack information of the sample tube rack. The tube rack information includes all samples carried on the sample tube rack and all samples to be tested Project; the sample analyzer is mainly used to detect the corresponding items of the samples to be tested loaded on the sample tube rack assigned to the sample analyzer according to its test items; the channel is connected between the loading platform, the sample analyzer and the unloading platform It is used for the dispatch and transfer of the sample tube rack between the loading platform, the sample analyzer and the unloading platform; the unloading platform is used to accommodate the sample tube rack after the inspection is completed.

In one embodiment, the channel includes at least one common channel and a dedicated channel for the sample analyzer. The common channel is used for the sample tube rack between the loading platform, the sample analyzer and the unloading platform, or between the sample analyzer and the sample analyzer. Transit. The dedicated channel is the channel that connects between the common channel and the sample analyzer for the sample tube rack to park in order to wait for the sample analyzer to detect. The sample tube racks of any scheduling path can be transferred through the common channel, and the sample tube racks are parked on the dedicated channel to avoid the public channel from being heavily occupied. When there are few samples to be tested, which will not cause a large number of conflicts in the sample tube rack during the scheduling process, a common channel can be used. This design can reduce the number of channels, which reduces the system volume to a certain extent and saves cost. In another embodiment, the channel is a dedicated channel, and each dedicated channel is only used to transfer the sample tube rack of the designated scheduling path. When there are many samples to be tested, the use of the dedicated channel can effectively prevent each sample tube rack from being scheduled. Conflicts occur during the process, shortening the detection time. In another embodiment, the channel may also have only a common channel, and the common channel transfer may be used to run a sample tube rack of any scheduling path. When there are few samples to be tested, the sample tube rack may be transferred through the common channel only. In a specific embodiment, the common channel can transport the sample tube rack in only one direction, or the sample tube rack can be transferred in two opposite directions. For example, the common channel is a double channel, one transfers the sample tube rack backward, and the other One transports the sample tube rack forward.

In actual work, the scheduling mechanism 12 is used to receive the scheduling instruction sent by the processing terminal 11 and transfer the sample tube rack to the target analyzer for inspection according to the scheduling path planned by the processor, which can pass the sample tube rack through the loading platform The channel is scheduled to the sample analyzer, the sample tube rack can also be scheduled between each sample analyzer, and the sample tube rack that has been tested can also be scheduled to the unloading platform.

Based on the above pipeline analysis system, all samples or specified samples on the pipeline can be monitored, for example, to monitor the test completion time. In some embodiments, the sample test completion time can be calculated in real time or according to a preset time interval. In some embodiments, it is also possible to calculate the inspection completion time of the sample after receiving the instruction to predict the inspection completion time of the sample. The following takes the real-time monitoring of the completion time of a specified sample as an example to illustrate its processing flow, as shown in Figure 3, including the following steps:

Step 31: Obtain the tube rack information of the sample tube rack. Before the sample is put into the pipeline test, the user enters the identification number of the sample and the inspection items to be performed through the human-machine interactive device, and assigns the sample tube rack to the sample, so that the initial tube rack information of the sample tube rack can be obtained. The information includes all pending items that have not been completed for all samples on the sample tube rack. When the scheduling mechanism removes the sample tube rack carrying the sample from the loading area, the scanner scans the barcode of the sample tube rack and starts scheduling and testing the sample tube rack. When the inspection items of the samples on the sample tube rack are completed one by one, the tube rack information of the sample tube rack is also gradually updated accordingly, and the tube rack information of the sample tube rack is acquired in real time.

In step 32, the target analyzer allocated to the item to be tested of the sample tube rack is inspected. According to the real-time sample tube rack tube rack information, the working state information of each sample analyzer and the real-time load information, the target analyzer to be tested for the sample tube rack to be tested is determined. Among them, the working status information refers to whether to support the item to be tested and whether the sample analyzer can work normally; the real-time load information refers to the current time, the number of samples waiting to be tested by each sample analyzer. It should be noted that the real-time sample tube rack information, the working status information of each sample analyzer and the real-time load information of each sample analyzer refer to the relevant information that is updated in real time at a predetermined time interval of the system or a time interval entered by the user .

When assigning a target analyzer to the sample tube rack, first find the analyzer that has the ability to check the item to be tested and is working normally according to the items to be tested of the sample tube rack. If there are multiple analyzers To check the ability of the item to be tested, an analyzer with a small number of loads is preferably selected to determine the target analyzer of the sample tube rack. When the sample analyzer is in a fault state, even if the number of loads is small, it is preferably not allocated to the sample tube rack as the target analyzer.

Step 33: Plan a scheduling path for the sample tube rack according to the target analyzer corresponding to the sample tube rack. Normally, the sample analyzer is arranged on one side of the channel along the channel. In a specific embodiment, it can be performed according to the sequence of the target analyzer's arrangement position, and the scheduling path can also be planned in consideration of the arrangement position of the target analyzer and the state of the target analyzer, for example, according to the arrangement position, working state and load of the target analyzer The information plans the scheduling path of the sample tube rack. For example, as shown in Figure 1, the target analyzers assigned to the sample tube racks are IVD1 and IVD2. The number of IVD1 loads is 5 and the number of IVD2 loads is 2. In order to complete the inspection as soon as possible, the better planned scheduling path may be First transfer the sample tube rack to IVD2, and then to IVD1. However, if IVD2 is currently in the state of replacing reagents, the better planned scheduling path may also be to first transfer the sample tube rack to IVD1, and then to IVD2.

After the scheduling path is determined, the processing terminal controls the scheduling mechanism to transfer the sample tube rack to each target analyzer for inspection according to the scheduling path. The scheduling mechanism receives the scheduling instruction and scheduling path information sent by the processing terminal, and transfers the sample tube rack through the channel according to the scheduling path. Please refer to FIG. 1, the scheduling mechanism can transfer the sample tube rack from the loading platform to each target analyzer, or can dispatch the sample tube rack between each target analyzer, or transfer the sample tube rack to the unloading platform. During the transfer process of the sample tube rack, the dispatch mechanism reads the dispatch path information from the processing terminal in real time. When the dispatch path changes, the dispatch mechanism subsequently changes the path of the sample tube rack.

Step 34: The processing terminal predicts the inspection completion time of the sample to be monitored according to the influencing factors. The influencing factors include the tube rack information of the sample tube rack, the load information of the target analyzer, the test speed and scheduling path of the target analyzer.

In a specific embodiment, according to the tube rack information of the sample tube rack, the load information of the target analyzer, the test speed of the target analyzer and the scheduling path, the test completion time for calculating the sample includes two parts, namely:

The sample to be monitored waits for the first time for the target analyzer to perform the inspection. The first time is calculated based on the tube rack information of the sample tube rack, the load information of the target analyzer, the inspection speed of the target analyzer, and the scheduling path. When the sample tube rack where the sample to be monitored is transferred to a target analyzer, it is not immediately tested, but there are some samples in front of the sample to be monitored waiting for the target analyzer to detect, the same sample tube rack It is also possible that some samples arranged in front of the sample to be monitored are waiting for detection by the target analyzer. Therefore, the sum of the time that the sample to be monitored needs to wait for each target analyzer to perform the inspection is the first time before the inspection is completed.

The sample to be monitored spends the second time on the transshipment route, and the second time is calculated based on the time of the public channel through which the sample to be monitored travels. The common channel is divided into multiple sections by multiple sample analyzers arranged on its side. The sample tube rack has a certain time after passing through each section. When the common channel section through which the sample to be monitored passes is determined, it spends on multiple sections The sum of the times is the second time.

The result of adding the first time and the second time is used as the prediction result of the test completion time of the sample to be monitored.

In this embodiment, the calculation process of the first time is shown in FIG. 4 and includes the following steps:

Step 40: Obtain the number of target analyzers corresponding to the sample to be monitored and the sample tube rack respectively.

In step 41, it is determined whether the number M of target analyzers corresponding to the sample tube rack is equal to 1, if yes, step 42 is performed, otherwise step 43 is performed.

Step 42: Calculate the first time according to formula (1).

T _meter = (N + 1) * V -------------- (1)

Wherein, T is a first time _tester, N being the number of samples for queuing target analyzer to be monitored prior to the sample tube when the sample rack is transported to the target analyzer, V is the velocity of the target test analyzer.

In step 43, the number M of target analyzers corresponding to the sample tube rack is greater than one.

In step 44, it is determined whether the number of target analyzers corresponding to the samples to be monitored is equal to 1, if yes, step 45 is performed, otherwise step 46 is performed.

Step 45: Determine whether the target analyzer corresponding to the sample to be monitored is the first target analyzer along the current scheduling path among the target analyzers corresponding to the sample tube rack. If so, perform step 47 and proceed according to formula (1) Calculate the first time, if not, go to step 46.

Step 46: Determine the travel order of the target analyzer according to the dispatch path, and determine the rank M2 on the dispatch path of the last target analyzer to be monitored by the sample to be monitored. M2 is an integer less than or equal to M.

Step 48: Calculate the time that the sample tube rack waits for the M1th target analyzer test according to formula (2), where M1 = 1, 2, ..., M2-1;

T _M1 = N _M1 * V _M1 -------------- (2)

Among them, T _M1 is the time that the sample tube rack waits for inspection by the M1 target analyzer, and N _M1 is the time when the sample tube rack is transferred to the M1 target analyzer and waits for the detection of the M1 target analyzer before arranging the sample tube rack The number of samples and the number of samples on the sample tube rack that need to be tested by the M1th target analyzer. V _M1 is the inspection speed of the M1th target analyzer.

From this, the time for the sample tube rack to wait for inspection by each target analyzer between T ₁ and T _M2-1 is calculated.

Step 49: When the sample tube rack is transferred to the M2th target analyzer, arrange the number of samples waiting for the M2th target analyzer to be detected before the sample to be monitored N _M2 , and calculate the sample to be monitored according to formula (3). Test time T _{M2 of M2} target analyzers;

T _M2 = (N _M2 +1) * V _M2 -------------- (3)

Among them, V _M2 is the inspection speed of the M2th target analyzer;

Step 50: Calculate the first time T _meter according to formula (4);

T _meter = T ₁ + ... + T _M2-1 + T _M2 ------------- (4).

After the first time and the second time are obtained, the two can be added to obtain the test completion time of the sample to be monitored. The inspection completion time refers to the time to complete all the test items of the sample to be monitored. The time can be an absolute time, such as 16:30; it can also be a relative time, such as how long it is from the current time to complete the test Time; it can also be a percentage of completion progress, for example, the total time for the sample to be monitored to complete the test is 120 minutes, and the current time has been completed by 60%.

In other embodiments, other methods may be used to calculate the inspection completion time of the sample based on the tube rack information of the sample tube rack, the load information of the target analyzer, the inspection speed of the target analyzer, and the scheduling path.

In step 35, the prompt information of the corresponding sample is output according to the inspection completion time, which is displayed on the display of the processing terminal, or the inspection completion time can be output to the query terminal for display based on the query instruction. In some embodiments, the prompt information includes at least one of the sample inspection completion time, the audit time after the inspection is completed, the unloading time, the recovery time, the report time, and the current location information of the sample; in another embodiment The prompt information includes at least one of the sample inspection completion time, the report reporting time, and the current location information of the sample. The prompt information can be updated in real time, or updated according to the update instruction input by the user, or when there are influencing factors changing, the prompt information is updated.

It should be pointed out that the calculation method of the unloading time is similar to the calculation of the inspection completion time of the sample to be monitored. The difference is that the unloading time needs to predict the inspection completion time of the last sample in the sample tube rack, and then add The upper sample tube rack is transferred from the last target analyzer to the unloading platform and the unloading time on the unloading platform to obtain the unloading time. The time for the report needs to be added to the time of the doctor's review and other possible time on the basis of the time of completion of the test.

Step 36: Monitor the changes of influencing factors in real time. During the inspection process, since the inspection of the sample is continuously completed, the tube rack information of the sample tube rack is continuously updated, and there are many aspects that also affect the load information and scheduling path of the target analyzer. For example, in some embodiments, the target analyzer is monitored in real time for failure or test interruption. When the target analyzer fails or the test is interrupted, the target analyzer of each sample tube rack is re-determined and the target analyzer's Load information and scheduling path. For example, when the target analyzer needs to be replaced with reagents or the target analyzer needs to be cleaned regularly, the test needs to be interrupted. When the target analyzer fails and the test is interrupted, the system is handled differently. The failure is an unpredictable situation, and the cause and maintenance time of the failure can not be determined; while the test interruption is within the controllable range, such as replacing reagents And the time required for regular cleaning can be determined, and then the interruption time can be determined. For two cases, the update of the scheduling path planning is different. For example, if only the reagent is replaced, the scheduling path may remain unchanged because of the short consumption time. However, if the target analyzer fails, the troubleshooting Time is uncertain, and the scheduling path is likely to change.

In some implementations, the system monitors in real time whether the sample tube racks collide with other sample tube racks in the common channel during the scheduling process. When a conflict occurs, the transportation queue is sorted according to a predetermined rule. In the back, you need to wait for the front sample tube rack to pass through the common channel. In this case, the scheduling path of the sample tube rack is added by a segment. When a conflict occurs in the common channel, the sample tube rack to be monitored can be allocated to other channels for transfer according to the information of the sample tube rack on the channel at the current time. In this case, the scheduling path of the sample tube rack will also change.

In some embodiments, the information of inserting the emergency sample tube rack is monitored in real time, and when the insertion of the emergency sample tube rack is monitored, the sample tube rack target analyzer is updated according to the tube rack information of the emergency sample tube rack and the position information of its insertion Load information and scheduling path. The emergency sample tube rack can be located on the loading platform or on the dedicated channel of the sample analyzer of the item to be tested. Different insertion positions of the emergency sample tube rack have different effects on the monitoring sample scheduling path. If the items to be tested for the emergency sample are different from the items to be tested for the sample tube rack to be monitored, or the emergency samples are arranged behind the sample tube rack to be monitored at the target analyzer, the dispatch path for the monitored sample will not be affected; if the emergency sample It has the same items to be tested as the sample tube rack to be monitored, and it is predicted that the emergency samples will be ranked before the sample tube rack to be monitored at the target analyzer. You need to change the load information of the target analyzer or combine it with the load of other sample analyzers. Situation, re-determine the target analyzer of each sample tube rack, and update the load information and scheduling path of the target analyzer.

When there is a change in the tube rack information of the sample tube rack, the load information of the target analyzer, and the scheduling path, it is fed back to step 34, so that the system predicts the test completion time of the sample based on the new influencing factors.

In this embodiment, the processor automatically reads in real time the tube rack information of the sample tube rack to which the sample to be monitored belongs, the load information of the target analyzer and the scheduling path, and then based on the read tube rack information needle, the load of the target analyzer The information and scheduling path predict the completion time of the samples to be monitored. The prediction result can be displayed on the display in real time, or the relevant information of the sample to be queried can be retrieved and output to the display for display when the user inputs the query instruction.

In another embodiment, the processor does not predict the test completion time of the sample to be monitored in real time. When the user (such as a medical staff) specifies to monitor a certain sample, the user selects the sample or enters the The identification number of the sample, and enter the instruction to predict the sample. Based on the instruction, the processor determines the sample tube rack to which the sample to be monitored belongs, and obtains the current tube rack information, target analyzer information, scheduling path and other information of the sample tube rack. Time to complete the inspection of the sample to be monitored.

The above-mentioned embodiment is mainly used for medical staff to inquire about the time of completion of examination. Based on the concept created by the present invention, it can also be used for patients or their families to inquire about the time of completion of examination of samples.

Referring to FIG. 5, on the basis of the embodiment shown in FIG. 1, the pipeline analysis system further includes a query terminal 14, which can be directly connected to the processing terminal 11 shown in FIG. 1, or to the hospital management system. The processing terminal is also connected to the hospital management system, so that the query terminal is indirectly connected to the processing terminal. The query terminal 14 is used to receive an instruction for querying a sample input by the user, and the command includes the identification number of the sample. The query terminal 14 is also used to output a query result. The query result may be the test result of the sample, or may be prompt information related to the test completion time of the sample. Normally, the processing terminal and the management system of the hospital are set up in the doctor ’s office or laboratory, and the query terminal is set up in the public service area of the hospital for users (such as patients or family members of patients) to inquire about the test situation of the samples. When the user inputs a query instruction, the query terminal extracts the query result from the processing terminal or the hospital's management system according to the instruction.

In some embodiments, please refer to FIG. 6, the query terminal includes a scanning area 641, a printing area 642, and a display area 643. The scanning area 641 is used to receive a query instruction input by a user. The instruction may be an identification coded information QR code or barcode, the user only needs to scan the QR code or barcode near the scanning area to complete the input of query instructions. In some embodiments, the scanning area is also equipped with a keyboard, which is used as a QR code Or when the barcode is damaged, the user manually enters the identification code.

Step 71: An instruction for querying the sample input by the user through the query terminal, the instruction including the identification number of the sample. The user can input the query instruction by scanning the code, or by manual input or tab.

Step 72: Based on the instruction, determine whether the sample to be queried has completed all inspection items. After the query terminal reads the query sample instruction, it sends a request to the processing terminal. After receiving the request, the processing terminal determines whether the sample to be queried has completed all the testing items. If the judgment result is "Yes", step 75 is performed; if the judgment result If no, go to step 73.

Step 73: After the processing terminal judges that the sample to be queried has not completed all the detection items, the processor predicts the inspection completion time of the sample to be queried based on the request. This includes:

The sample tube rack to which the sample to be queried belongs is determined based on the instruction for querying the sample, and the tube rack information of the sample tube rack is obtained, and the tube rack information includes the currently unfinished items to be tested of all samples on the sample tube rack.

Obtain the target analyzer for the test item of the sample tube rack, the load information of the target analyzer, the inspection speed of the target analyzer, and the scheduling path of the sample tube rack. The target analyzer allocates the target analyzer to the items to be tested of the sample tube rack according to the real-time tube rack information of the sample tube rack, the working status information of each sample analyzer and the real-time load information. . Work status information refers to whether the project to be tested is supported. The scheduling path is planned according to the target analyzer currently corresponding to the sample tube rack. For the specific planning method, refer to the foregoing embodiment.

The test completion time of the sample is calculated according to the tube rack information of the sample tube rack, the load information of the target analyzer, the test speed of the target analyzer and the dispatch path.

In this application, the pipeline analysis system updates the pipe rack information of each sample pipe rack in real time, the load information of the target analyzer, and the scheduling path. In some embodiments, the pipeline analysis system also monitors in real time whether the information of the emergency sample tube rack is inserted, whether the target analyzer is malfunctioning or the test is interrupted. When it is detected that the emergency sample tube rack is currently inserted, the The pipe rack information updates the load information and scheduling path of the target analyzer. When the current target analyzer fails or the test is interrupted, the target analyzer of each sample tube rack is re-determined, and the load information and scheduling path of the target analyzer are updated.

Step 74: The processing terminal outputs prompt information related to the inspection completion time of the sample to be queried to the query terminal for display. The prompt information includes at least one of the sample inspection completion time, the report reporting time, and the current location information of the sample. At this time, the user can see the prompt information related to the sample to be queried on the query terminal, and according to the prompt information, select the appropriate time to query the detection result according to his own time schedule.

Step 75: After the processing terminal judges that the sample to be queried has completed all the testing items, the processor will directly retrieve the test result of the sample and output it through the query terminal. For example, the test result can be printed out through the printing area of the query terminal, or the electronic version test result can be directly queried through the query terminal.

With this embodiment, the user can directly inquire on the query terminal when the sample can complete the inspection. In some embodiments, when the user does not need to output the inspection result, step 72 can also be deleted, and it is no longer judged whether the sample to be queried has completed all the inspection items, but directly output prompt information related to the inspection completion time of the sample, for example When the inspection is completed, similar information such as completed or issued reports can be output. When the query terminal is suitable for doctors to query, the query terminal can also be integrated into the human-computer interaction device.
