Description

Sample analysis device and maintenance system and method thereof

Technical Field

The present invention relates to a sample analyzer, a maintenance system for the sample analyzer, and a maintenance method for the sample analyzer.

Background

Sample analysis devices, such as biochemical analyzers, immunological analyzers, and the like, are devices for analyzing and measuring samples. In order to ensure that the performance of the sample analysis device is reliable and in a good working state and prolong the service life of equipment, the sample analysis device needs to be regularly maintained strictly according to the requirement; for example, in order to maintain the excellent performance of the instrument, the reaction cup, the stirring rod, the sample needle and the reagent needle of the biochemical analyzer need to be cleaned in a reinforced manner regularly, the cup grabbing hand, the liquid path and the like of the instrument need to be maintained, and after each maintenance, the maintenance history and the problems occurring in the maintenance process need to be recorded so as to confirm the operation condition of the instrument or trace the fault cause later.

The inventor researches and discovers that two main situations exist in the maintenance of the sample analysis device at present, namely, the periodic maintenance is carried out on a single sample analysis device which works independently, and the periodic maintenance is carried out on a plurality of sample analysis devices which are cascaded to form a system.

For example, taking regular maintenance of a sample analysis device for a single independent operation as an example, fig. 1 is a general maintenance flow, the instrument first judges whether a maintenance item needs to be executed on the same day or currently, if yes, marks the corresponding maintenance item, a user can know which maintenance item needs to be executed currently by checking a maintenance label on an operation interface, then the user can enter the maintenance interface, selects a marked maintenance item, then clicks the execution, then displays the precondition of the maintenance item, the user prepares according to the precondition displayed by the instrument, clicks the corresponding maintenance item after the preparation, then executes the corresponding maintenance item and stays on the current maintenance interface, when the maintenance item is executed, the instrument enters a maintenance history interface, the user manually registers maintenance history (such as a maintenance operator, the execution time, the name of the maintenance item, and some details of the execution process (whether error and maintenance result exist, etc.), and the instrument updates the maintenance record according to the maintenance history registered by the user; the user then repeats the above process back to the maintenance interface to begin and proceed to the next maintenance item, and so on, until all marked maintenance items have been performed.

The process of carrying out periodic maintenance on a plurality of sample analysis devices which are cascaded to form a system is similar, except that one sample analysis device is selected at each time on a maintenance interface, then after the sample analysis device is maintained, the next sample analysis device is selected at the maintenance interface for subsequent maintenance.

The present technician often only pays attention to the specific content of each maintenance item, such as which maintenance items need to be carried out and how the period of the maintenance items are determined, but the specific maintenance procedure is not very concerned, and the inventor finds that when researching the maintenance procedure of the sample analysis device, the current maintenance procedure has a plurality of inconveniences and places to be improved.

Detailed Description

The application will be described in further detail below with reference to the drawings by means of specific embodiments. Wherein like elements in different embodiments are numbered alike in association. In the following embodiments, numerous specific details are set forth in order to provide a better understanding of the present application. However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, related operations of the present application have not been shown or described in the specification in order to avoid obscuring the core portions of the present application, and may be unnecessary to persons skilled in the art from a detailed description of the related operations, which may be presented in the description and general knowledge of one skilled in the art.

Furthermore, the described features, operations, or characteristics of the description may be combined in any suitable manner in various embodiments. Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.

The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The term "coupled" as used herein includes both direct and indirect coupling (coupling), unless otherwise indicated.

The sample analysis device is provided with the maintenance items and the regular maintenance time of the maintenance items, but the maintenance flow is also important, and a convenient and simple maintenance flow can lead the user to conveniently maintain the sample analysis device, so that the maintenance flow can not only ensure the effective execution of the maintenance items, prevent the user from not strictly executing regular maintenance because of the complicated maintenance flow, but also improve the working efficiency of the user and the instrument, and save the time of the user because of the convenient and simple maintenance flow.

The inventors found that there are many inconveniences and improvements in the current maintenance flow when studying the maintenance flow of the sample analysis apparatus. For example, when a single sample analysis device for independent operation or a plurality of sample analysis devices for cascade connection are maintained, only single selection is supported on a maintenance interface, one maintenance item is selected for execution each time, and after the execution of the maintenance item is completed, the next maintenance item is selected on the maintenance interface, wherein the maintenance process is not only required to prepare a precondition for the selected maintenance item each time separately, but also the next maintenance item is required to be selected again manually, so that the operation is very tedious and inconvenient; for example, when a specific maintenance item is executed, the operation interface is occupied, so that a user can only wait for the end of the maintenance item and can not perform other operations, for example, the operation interface is used for checking reagent information and the like, so that reagents with insufficient allowance can be supplemented by using the time, the time is saved, and the efficiency is improved; for example, after the maintenance project is executed, the user needs to manually fill in the maintenance record, which is not only inefficient and complicated, but also easy to falsify, for example, the user falsifies the maintenance record. The inventors have devised corresponding improvements for those maintenance procedures that have long been unappreciated, ignored, and not found by those skilled in the art, and the following detailed description.

First, a maintenance flow of a sample analyzer for a single independent operation will be described.

Referring to fig. 2, the sample analyzer of an embodiment includes a sample section 10, a reagent section 20, a measurement section 30, and a controller 40, and may further include a display 50 in an embodiment. The sample unit 10 is used for carrying a sample to be tested, and the sample is sucked and then provided to the measurement unit 30. The reagent unit 20 is for carrying a reagent, and the reagent is supplied to the measurement unit 30 after being suctioned. The measuring section 30 is used for measuring a sample to obtain a project test result of the sample. The measurement of the sample involves the cooperation of the components, and if some of the components are not effectively maintained in time, the measurement result of the sample may be affected, and the reliability, the service life and the like of the instrument may be reduced; periodic and efficient maintenance of the sample analysis device is therefore necessary.

In one embodiment, the controller 40 determines a plurality of maintenance items currently required to be performed, and controls the sample analysis device to execute the determined plurality of maintenance items. In one embodiment, the controller 40 may determine which of the maintenance items may be parallel and which may need to be serial before controlling the sample analyzer to execute the determined plurality of maintenance items, and then controlling the sample analyzer to execute the maintenance items that may be parallel and execute the maintenance items that may not be parallel in parallel, so that time may be greatly saved. In one embodiment, when it is determined that the sample analyzer has performed the determined plurality of maintenance items, the controller 40 also automatically updates the maintenance records, including the operator, the time of maintenance, the process record of maintenance, etc. (e.g., whether there is an error in reporting, the maintenance result, etc.), so that the user does not have to care about the registration of the maintenance history or the maintenance record, and the problem of falsification of the maintenance record is avoided.

The controller 40 may determine the plurality of maintenance items currently required to be performed, or may automatically determine a plurality of preset maintenance items, or may provide a related interface for a user to select, which will be described below.

For example, in one embodiment the controller 40 determines that a plurality of maintenance items currently require to be performed includes: and when judging that the current maintenance trigger event is a preset maintenance trigger event, determining a plurality of preset maintenance items as maintenance items which are required to be performed currently. In an embodiment the maintenance triggering event comprises power on and/or power off. One common scenario is that the manufacturer sets a plurality of maintenance items on the operation interface before the instrument leaves the factory or before the user starts the machine, and when the user starts the machine, the controller 40 controls the sample analysis device to execute the preset plurality of maintenance items, or when the user shuts down the machine, the controller 40 controls the sample analysis device to execute the preset plurality of maintenance items, and after execution is completed, the machine is automatically shut down.

For example, in one embodiment, the controller 40 controls the display 50 to display an item maintenance interface on a current operation interface, for receiving a user selection instruction for a plurality of maintenance items; in response to a user selection instruction of the plurality of maintenance items, the controller 40 determines the plurality of maintenance items selected by the user as maintenance items currently required to be performed. Referring to fig. 3 (a), a general scenario is that the current operation interface is an item maintenance interface, a user selects a plurality of maintenance items through a mouse or a keyboard on the item maintenance interface, and after clicking a determination button, the controller determines the plurality of maintenance items selected by the user as maintenance items that need to be performed currently, where a check box in the same column of each maintenance item in fig. 3 (a) is used for the user to select a corresponding maintenance item. Referring to fig. 3 (b), another general scenario is that one or more maintenance items are all provided with a maintenance period, that is, are set to be required to be maintained every time, so that the controller 40 pushes the maintenance item on the same day or that currently needs to be executed to the item maintenance interface, the user selects all or more maintenance items through a mouse or a keyboard, and after clicking a determination button, the controller 40 determines the maintenance items selected by the user as maintenance items currently required to be executed; the user selects a maintenance item required in the maintenance item list on the right by selecting the maintenance on the same day in the maintenance type list on the left in fig. 3 (b).

In one embodiment, after determining the plurality of maintenance items currently required, the controller 40 further controls the display 50 to display the preconditions on the current operation interface, for example, by popup. Specifically, after determining a plurality of maintenance items that need to be performed currently, the controller 40 determines a precondition for each maintenance item, and controls the display 50 to display at least the unsatisfied maintenance items and the preconditions thereof on the current operation interface; alternatively, the controller 50 controls the display 50 to display the preconditions of the maintenance items on the current operation interface after determining the plurality of maintenance items that are currently required to be performed. The preconditions of the maintenance items are displayed in batches, so that a user can prepare all the preconditions at one time, the interaction time of the user is reduced, and the efficiency is improved. When it is determined that each of the plurality of maintenance items currently required to be performed satisfies the respective preconditions, for example, the controller 40 automatically judges or responds to an instruction entered by the user to determine that the preconditions are satisfied, the controller 40 controls the sample analysis device to execute the maintenance items. Fig. 4 shows an example, when the controller 40 determines that the maintenance items do not satisfy the preconditions, for example, the remaining amount of the cleaning solution is insufficient, the controller 40 generates and controls the display 50 to display a pop-up window as shown in the drawing, after the user clicks the pop-up window to confirm, the user can perform the replenishment of the cleaning solution on the relevant interface, and then reselect the maintenance items to perform the maintenance, or the user can directly reselect the maintenance items to delete the maintenance items which do not satisfy the preconditions, for example, delete the maintenance items which need the cleaning solution, and do not perform the maintenance this time.

When the controller 40 controls the sample analysis device to execute the plurality of maintenance items, that is, when or during the sample analysis device starts executing the maintenance items, the controller 40 in one embodiment controls the display 50 to exit the item maintenance interface from the current operation interface and enter the background operation. Therefore, the current operation interface is not blocked on the project maintenance interface, and a user can browse other information at the same time, such as reagent information, quality control information and/or calibration information and the like, so that consumables such as reagents and calibration products are prepared at the same time in the process of project maintenance, time is saved, and efficiency is improved. Of course, in an embodiment, after the controller 40 controls the display 50 to exit the current operation interface and enter the background operation, the controller also controls the display 50 to display the test condition information on the current operation interface, and in an embodiment, the test condition information includes reagent information, quality control information and/or calibration information, so that the related information can be automatically presented to the user without the need of the user to check manually.

In an embodiment, when it is determined that the sample analysis device has performed the determined plurality of maintenance items, the controller 40 controls the display 50 to display the maintenance result on the current maintenance interface for the user to view, and also plays a role in reminding the user that the current maintenance has ended.

When the controller 40 controls the sample analysis device to execute the plurality of maintenance items, the item maintenance interface exits the current operation interface and is put into an execution list of the background, and when the background is executed, the execution result is notified to the current operation interface, so that the background maintenance well realizes the business separation of the front end and the background, and the user can also use the information of other function interfaces during the background maintenance.

The embodiment of the invention also discloses a maintenance method of the sample analysis device. Referring to fig. 5, the maintenance method of an embodiment includes steps 100 to 120.

Step 100: a plurality of maintenance items currently in need of performance are determined. Step 100 may determine a plurality of maintenance items that need to be performed currently, which may be automatically determined by a plurality of preset maintenance items, or may provide a related interface for a user to select, which will be described below.

For example, in one embodiment step 100, determining a plurality of maintenance items that are currently in need of performance includes: and when judging that the current maintenance trigger event is a preset maintenance trigger event, determining a plurality of preset maintenance items as maintenance items which are required to be performed currently. In an embodiment the maintenance triggering event comprises power on and/or power off. One common scenario is that a manufacturer sets a plurality of maintenance items on an operation interface before the instrument leaves the factory or before a user starts the machine, and step 100 controls the sample analysis device to execute the preset plurality of maintenance items when the user starts the machine, or step 100 controls the sample analysis device to execute the preset plurality of maintenance items when the user shuts down the machine, and then automatically shuts down the machine after the execution is completed.

For example, in one embodiment, step 100 displays an item maintenance interface on a current operation interface, for receiving a user selection instruction for a plurality of maintenance items; in response to a user selection instruction for a plurality of maintenance items, step 100 determines the plurality of maintenance items selected by the user as maintenance items currently required to be performed. One general scenario is that the current operation interface is an item maintenance interface, where after a user selects a plurality of maintenance items through a mouse or a keyboard, and clicks a determination button, step 100 determines the plurality of maintenance items selected by the user as maintenance items that need to be performed currently. Another general scenario is that one or more maintenance items are all set with a maintenance period, that is, how often maintenance is required, so step 100 pushes maintenance items that are required to be performed on the same day or currently to the item maintenance interface, the user selects all or more of the maintenance items through a mouse or a keyboard, and after clicking a determination button, step 100 determines those maintenance items selected by the user as maintenance items that are required to be performed currently.

Referring to fig. 6, in one embodiment, the maintenance method may further include step 110: the preconditions are displayed on the current operating interface, for example by means of a pop-up window. Step 100 after determining the plurality of maintenance items that are currently required to be performed, step 110 also displays preconditions on the current operator interface. Specifically, after determining a plurality of maintenance items that need to be performed at present in step 100, step 110 determines a precondition for each maintenance item, and displays at least unsatisfied maintenance items and preconditions thereof on a current operation interface; alternatively, after determining the plurality of maintenance items that need to be performed currently, step 100 displays the preconditions of each maintenance item on the current operation interface, step 110. The preconditions of the maintenance items are displayed in batches, so that a user can prepare all the preconditions at one time, the interaction time of the user is reduced, and the efficiency is improved. When it is determined that each of the plurality of maintenance items currently required to be performed satisfies the respective preconditions, for example, step 110 automatically judges or responds to an instruction input by the user to determine that the preconditions are satisfied, the following step 120 is performed; if the precondition is not satisfied, the user is waited to prepare the corresponding precondition or the user can delete the maintenance items which do not satisfy the precondition.

Step 120: the sample analysis device is controlled to execute the determined plurality of maintenance items. In one embodiment, step 120 may determine which of the maintenance items may be parallel and which may need to be serial before controlling the sample analyzer to execute the determined plurality of maintenance items, and then controlling the sample analyzer to execute the maintenance items that may be parallel and execute the maintenance items that may not be parallel in parallel, which may save time greatly.

When step 120 controls the sample analysis device to execute the plurality of maintenance items, i.e. when or during the sample analysis device starts executing the maintenance items, step 120 in one embodiment exits the item maintenance interface from the current operation interface and enters the background operation. Therefore, the current operation interface is not blocked on the project maintenance interface, and a user can browse other information at the same time, such as reagent information, quality control information and/or calibration information and the like, so that consumables such as reagents and calibration products are prepared at the same time in the process of project maintenance, time is saved, and efficiency is improved. Of course, in one embodiment, step 120 displays the test condition information on the current operation interface after the item maintenance interface exits the current operation interface and enters the background operation, and in one embodiment, the test condition information includes reagent information, quality control information and/or calibration information, so that the relevant information can be automatically presented to the user without the user having to check manually.

In an embodiment, when it is determined that the sample analysis device has performed the determined plurality of maintenance items, step 120 further displays the maintenance result on the current maintenance interface for the user to view, and also plays a role in reminding the user that the current maintenance has ended.

Referring to fig. 7, in one embodiment, the maintenance method may further include step 130: when it is judged that the sample analysis device has completed executing the determined plurality of maintenance items, the maintenance record is automatically updated. For example, the maintenance records include operators, maintenance time, maintenance process records (such as error reporting, maintenance results, etc.), so that users do not need to care about the registration problem of the maintenance history or the maintenance records, and the problem of falsification of the maintenance records is avoided.

The above description is about the maintenance flow of the sample analyzer for a single independent operation, and a specific user operation scenario will be described below with reference to fig. 8.

The controller 40 first determines whether the maintenance items are required to be executed on the same day or currently, if yes, marks the corresponding maintenance items, the user can know which maintenance items are required to be executed currently by checking the maintenance label on the item maintenance interface, then the user can enter the item maintenance interface, the item maintenance interface supports simultaneous selection of a plurality of maintenance items, therefore, the user selects a plurality of marked maintenance items on the item maintenance interface, then clicks to execute, then the display 50 displays the preconditions of the maintenance items, the user prepares the preconditions of the maintenance items at one time, then clicks to confirm, then the sample analysis device executes the maintenance items, the display 50 transfers the item maintenance interface to the background, so that the user can browse reagent, calibration, quality control and other information on the current operation interface in the process to prepare consumable materials such as reagents, calibrators and the like, and the sample analysis device can inform the current operation interface of maintenance results after the maintenance items are controlled, and meanwhile, the maintenance records can be updated automatically.

The invention improves the maintenance flow of the sample analysis device for single independent operation, supports the multi-selection and batch execution of maintenance items, ensures that a user can prepare the precondition at one time, reduces the user interaction and improves the efficiency; the invention supports the background execution of maintenance items, so that the current operation interface is not blocked on the item maintenance interface, and a user can browse reagent, calibration and quality control information at the same time so as to prepare consumable materials such as reagent, calibration materials and the like at the same time, thereby saving time; the invention automatically records the maintenance record, the user does not need to care about the registration of the maintenance record, the counterfeits of the maintenance record are avoided, and the project maintenance is effectively executed.

The maintenance flow of the plurality of cascaded sample analyzers is described below.

An embodiment of the invention discloses a maintenance system of a sample analysis device, which can maintain a plurality of sample analysis devices. Referring to fig. 9, in one embodiment, the maintenance system includes a plurality of sample analyzers 60 and a controller 70, and in one embodiment, a display 80 may be included. In one embodiment, the controller 70 determines one or more sample analysis devices 60 currently in need of maintenance; for each sample analysis device 60 determined, the controller 70 determines one or more maintenance items currently required to be performed, and controls the sample analysis device 60 to perform the respective determined maintenance items. When a plurality of sample analyzers 60 need to perform maintenance of items, the controller 70 can control the sample analyzers 60 to execute the respective maintenance items in parallel, since the maintenance of the sample analyzers 60 is independent of each other and does not interfere with each other; when the controller 70 controls a specific sample analyzer to execute a plurality of maintenance items, it can determine which maintenance items can be parallel and which maintenance items need to be serial, and then control the sample analyzer 60 to execute the maintenance items which can be parallel and execute the maintenance items which cannot be parallel in parallel, so that time can be greatly saved. In one embodiment, when it is determined that any one of the sample analysis devices 60 has performed the determined maintenance item, the controller 70 automatically updates the maintenance record of the sample analysis device, where the maintenance record includes an operator, a time of maintenance, a process record of maintenance, etc. (e.g., whether there is an error in reporting, a maintenance result, etc.), so that the user does not have to care about the registration of the maintenance history or the maintenance record, and the problem of falsification of the maintenance record is avoided.

The determination of the sample analysis device and corresponding maintenance items currently in need of such a process by the controller 70 may be automatic or may be provided with a relevant interface for selection by the user, as described below.

For example, in one embodiment, when the current is the preset maintenance trigger event, the controller 70 determines all the sample analysis devices 60 as the sample analysis devices that currently need to be maintained, and determines the preset plurality of maintenance items as the maintenance items that each sample analysis device 60 currently needs to perform. In an embodiment, the maintenance triggering event includes power on and/or power off. One common scenario is that a manufacturer sets a plurality of maintenance items on an operation interface before the instrument leaves the factory or before a user sets the same maintenance items or corresponding maintenance items for each cascaded sample analysis device 60, when the user starts up, the controller 70 controls the cascaded sample analysis devices 60 to execute the respective corresponding preset maintenance items, or when the user shuts down, the controller 70 controls the cascaded sample analysis devices to execute the respective corresponding maintenance items, and after the execution is completed, the operation is automatically shut down.

For example, in one embodiment, the controller 70 controls the display 80 to display an item maintenance interface on the current operation interface, for receiving a user selection instruction for the sample analysis device, and receiving a user selection instruction for a maintenance item of the selected sample analysis device; the controller 70 determines the sample analysis device selected by the user as the sample analysis device currently requiring maintenance in response to a user selection instruction of the sample analysis device; the controller 70 determines maintenance items currently required to be performed for each sample analysis device selected by the user in response to a user selection instruction of the maintenance items for the selected sample analysis device. Referring to fig. 10 (a), a general scenario is that a current operation interface is an item maintenance interface, a user selects one sample analysis device at the item maintenance interface through a mouse or a keyboard, and then selects one or more maintenance items, after clicking a save button, the controller 70 determines the sample analysis device selected by the user as a sample analysis device currently requiring maintenance, determines the maintenance item selected by the user as a maintenance item required by the sample analysis device, then the user repeats the above process to select the next sample analysis device to maintain the maintenance item, and finally clicks to determine that the sample analysis device and the maintenance item required to be maintained have been selected; in fig. 10 (a), a sample analyzer may be selected in a drop-down frame of the apparatus, where M1 is a code of one of the sample analyzers. Referring to fig. 10 (b), another general scenario is that one or more maintenance items are all provided with a maintenance period, that is, are set to be required to be maintained every time, so that the controller 70 pushes maintenance items required to be executed by each sample analysis device on the same day or at present to the item maintenance interface, the user selects the sample analysis device required to be maintained and the maintenance items thereof respectively through a mouse or a keyboard, etc., and after clicking a determination button, the controller 70 determines the sample analysis device selected by the user and the maintenance items corresponding to the sample analysis device required to be executed currently as the sample analysis device required to be executed and the maintenance items required to be executed; in fig. 10 (b), the user selects the maintenance type list on the left to be maintained on the same day, and then the sample analysis devices to be maintained on the same day appear in the middle sample analysis device list, and the user checks the check boxes in the same column of each sample analysis device to indicate that the sample analysis device is selected; if the sample analysis device with the code number M2 is currently selected, the maintenance item currently required by the sample analysis device with the code number M2 will appear in the rightmost maintenance item list, and the user can select the required maintenance item in the right maintenance item list.

For each sample analysis device 60 determined, after the controller 70 determines one or more maintenance items that need to be performed currently, the display 80 is further controlled to display the preconditions on the current operation interface, for example, by popup window, so that the preconditions of the maintenance items that need to be performed by all sample analysis devices 60 that need to be maintained currently can be displayed at one time. Specifically, the controller 70 judges the precondition of each maintenance item, and controls the display 80 to display at least the maintenance items of the sample analysis device 60 that are not satisfied and the precondition thereof at the current operation interface; or the controller 70 controls the display 80 to display the preconditions of the maintenance items of one or all of the sample analysis apparatuses 60 at the current operation interface. The preconditions of the maintenance items are displayed in batches, so that a user can prepare all the preconditions at one time, the interaction time of the user is reduced, and the efficiency is improved. For any one of the sample analysis devices 60, when it is determined that each of the maintenance items to be performed by the sample analysis device 60 satisfies the respective preconditions, for example, the controller 70 automatically judges or responds to an instruction entered by the user to determine that the preconditions are satisfied, the controller 70 controls the sample analysis device 60 to execute the determined maintenance items. Fig. 11 shows an example, where the controller 70 determines that the maintenance items do not satisfy the preconditions, for example, the remaining amount of the cleaning liquid is insufficient, the controller 70 generates and controls the display 80 to display a pop-up window as shown in the drawing, and after the user clicks the pop-up window to confirm, the user can remove the relevant interface to supplement the cleaning liquid and then reselect the maintenance items to perform maintenance, or the user can directly reselect the maintenance items, delete the sample analysis device or the maintenance items that do not satisfy the preconditions, for example, delete the maintenance items that require the cleaning liquid, and do not perform these maintenance items this time.

In one embodiment, when the controller 70 controls the sample analysis device 60 to execute the respective determined maintenance items, the controller 70 controls the display 80 to exit the item maintenance interface from the current operation interface and enter the background operation. Therefore, the current operation interface is not blocked in the project maintenance interface, and the user can browse other information at the same time, such as reagent information, quality control information and/or calibration information and the like in the current operation interface, so that consumables such as reagents and calibrators are prepared for each sample analysis device 60 in the project maintenance process, time is saved, and efficiency is improved. Of course, in an embodiment, after the controller 70 controls the display 80 to exit the current operation interface and enter the background operation, the controller 80 is further controlled to display the test condition information of each sample analyzer 60 on the current operation interface, and in an embodiment, the test condition information includes reagent information, quality control information and/or calibration information, so that the relevant information can be automatically presented to the user without the user having to manually check the relevant information again.

In one embodiment, when any or all of the sample analysis devices 60 are judged to have performed the determined maintenance items, the controller 70 controls the display 80 to display the maintenance results on the current maintenance interface for the user to view, and also functions as a reminder to the user that the maintenance of one or all of the sample analysis devices 60 is completed.

The embodiment of the invention also discloses a maintenance method of the sample analysis device, which can maintain a plurality of sample analysis devices. Referring to fig. 12, the maintenance method of an embodiment includes steps 200 to 220.

Step 200: one or more sample analysis devices of the plurality of sample analysis devices that are currently in need of maintenance are determined. Step 20 determines the sample analysis device and corresponding maintenance items currently required to be performed, either automatically or by providing a relevant interface for selection by the user, as described below.

For example, in one embodiment, when the current is determined to be the preset maintenance triggering event, step 200 determines all the sample analysis devices as the sample analysis devices that need to be maintained currently, and determines a plurality of preset maintenance items as the maintenance items that need to be performed currently for each sample analysis device. In an embodiment, the maintenance triggering event includes power on and/or power off. One common scenario is that a manufacturer sets a plurality of maintenance items on an operation interface before the instrument leaves the factory or before a user sets the same maintenance items or corresponding maintenance items for each cascaded sample analysis device, and when the user starts up, step 200 controls the cascaded sample analysis devices to execute the respective corresponding preset maintenance items, or when the user shuts down, step 200 controls the cascaded sample analysis devices to execute the respective corresponding maintenance items, and after the execution is completed, the system is automatically shut down.

For example, in one embodiment, step 200 displays an item maintenance interface on a current operation interface, for receiving a user selection instruction for a sample analysis device, and receiving a user selection instruction for a maintenance item of the selected sample analysis device; step 200, responding to a selection instruction of a user for the sample analysis device, and determining the sample analysis device selected by the user as the sample analysis device which needs to be maintained currently; step 200 determines maintenance items currently required to be performed by each sample analysis device selected by the user in response to a user selection instruction of the maintenance items of the selected sample analysis device. One general scenario is that the current operation interface is an item maintenance interface, the user selects one sample analysis device at the item maintenance interface through a mouse or a keyboard, and then selects one or more maintenance items, after clicking a save button, step 200 determines the sample analysis device selected by the user as the sample analysis device currently requiring maintenance, and determines the maintenance item selected by the user as the maintenance item required by the sample analysis device, and then the user repeats the above process to select the next sample analysis device for maintenance. Another general scenario is that one or more maintenance items are set with a maintenance cycle, that is, are set with a maintenance time interval, so step 200 pushes maintenance items to be executed by each sample analysis device on the same day or at present to the item maintenance interface, the user selects the sample analysis device and the maintenance item thereof to be determined to be required to be maintained through a mouse or a keyboard, and after clicking a determination button, step 200 determines the sample analysis device and the maintenance item corresponding to the sample analysis device selected by the user as the sample analysis device and the maintenance item required to be executed at present.

Referring to fig. 13, in one embodiment, the maintenance method may further include step 210: the preconditions are displayed on the current operating interface, for example by means of a pop-up window. For each sample analysis device determined, after determining one or more maintenance items to be performed currently, step 200 further displays the preconditions on the current operation interface, for example, by means of a popup window, so that the preconditions of the maintenance items to be performed by all sample analysis devices to be maintained currently can be displayed at one time. Specifically, step 210 judges the precondition of each maintenance item, and displays at least the unsatisfied maintenance item of the sample analysis device and its precondition on the current operation interface; or step 210 displays a precondition for a maintenance item for one or all of the sample analysis devices at the current operator interface. The preconditions of the maintenance items are displayed in batches, so that a user can prepare all the preconditions at one time, the interaction time of the user is reduced, and the efficiency is improved. For any one of the sample analysis apparatuses, when it is determined that each maintenance item to be performed by the sample analysis apparatus satisfies the respective precondition, for example, step 210 automatically judges or responds to an instruction input by the user that the determination satisfies the precondition, the following step 220 is performed. If the preconditions are not met, the user is waited to prepare the corresponding preconditions or the user may delete sample analysis devices or maintenance items that do not meet the preconditions.

Step 220: the sample analysis device is controlled to execute the respective determined maintenance items. In one embodiment, when the sample analysis devices are controlled to execute the respective determined maintenance items in step 220, and when there are a plurality of sample analysis devices that need to perform the maintenance of the items, since the maintenance between the sample analysis devices is independent of each other and will not interfere with each other, step 220 can control the sample analysis devices to execute the respective maintenance items in parallel; in step 220, when a specific sample analysis device is controlled to execute a plurality of maintenance items, it can be determined which of the maintenance items can be parallel and which need to be serial, and then the sample analysis device is controlled to execute the maintenance items which can be parallel in parallel and execute the maintenance items which cannot be parallel in serial, so that time can be greatly saved.

In one embodiment, step 220 further exits the project maintenance interface from the current operation interface and enters the background operation when controlling the sample analysis device to execute the respective determined maintenance project. Therefore, the current operation interface is not blocked on the project maintenance interface, and a user can browse other information at the same time, such as reagent information, quality control information and/or calibration information and the like, so that consumables such as reagents and calibrators are prepared for each sample analysis device in the project maintenance process, time is saved, and efficiency is improved. Of course, in one embodiment, after the project maintenance interface exits the current operation interface and enters the background operation, the test condition information of each sample analysis device is displayed on the current operation interface, and in one embodiment, the test condition information includes reagent information, quality control information and/or calibration information, so that the relevant information can be automatically presented to the user without the user having to check manually.

In one embodiment, when it is determined that any or all of the sample analysis devices have performed the determined maintenance items, step 220 displays the maintenance results on the current maintenance interface for the user to view, and also serves to alert the user to the end of maintenance of one or all of the sample analysis devices.

Referring to fig. 14, in one embodiment, the maintenance method may further include step 230: when it is judged that any one of the sample analysis devices has completed executing the determined maintenance items, the maintenance record of the sample analysis device is automatically updated. For example, the maintenance records include operators, maintenance time, maintenance process records (such as error reporting, maintenance results, etc.), so that users do not need to care about the registration problem of the maintenance history or the maintenance records, and the problem of falsification of the maintenance records is avoided.

The above is some descriptions of the maintenance procedures of the multiple cascaded sample analysis devices, and a specific user operation scenario will be described below with reference to fig. 15.

The controller 70 first determines whether a maintenance item needs to be executed on the same day or currently, if yes, marks the corresponding maintenance item, the user can know which sample analysis devices need to be executed on the same day by checking the maintenance label on the item maintenance interface, then the user can enter the item maintenance interface, the item maintenance interface supports to select a plurality of sample analysis devices to execute maintenance simultaneously, each sample analysis device can also select a plurality of maintenance items, therefore, the user selects one or a plurality of sample analysis devices and the corresponding maintenance items on the item maintenance interface, then clicks to execute, then the display 80 displays the preconditions of the maintenance items of the sample analysis devices, the user prepares the preconditions of the maintenance items at one time, then clicks to determine, then the sample analysis devices execute the respective maintenance items, the display 80 transfers the item maintenance interface to the background, so that the user can browse information such as reagents, calibration and quality control materials on the one hand, so as to prepare the consumable materials on the current operation interface on the basis, and after the control of the items, the controller 80 can inform the maintenance results to update the current operation interface automatically.

The invention improves the maintenance flow of a plurality of cascaded sample analysis devices, supports the simultaneous maintenance of a plurality of sample analysis devices, ensures that a user can prepare a precondition at one time, reduces user interaction and improves the efficiency; meanwhile, a plurality of sample analysis devices can execute maintenance in parallel, so that time is saved; the invention also supports the background execution of maintenance items, so that the current operation interface is not blocked on the item maintenance interface, and a user can browse reagent, calibration and quality control information at the same time so as to prepare consumable materials such as reagents, calibration products and the like at the same time, thereby saving time; the invention automatically records the maintenance record, the user does not need to care about the registration of the maintenance record, the counterfeits of the maintenance record are avoided, and the project maintenance is effectively executed.
