Description

[Technical field]

[0001] The present invention relates to a work assistance system that assists in work performed by medical equipment, and a program executed by the work assistance system. [Background technology]

[0002] Periodic maintenance of medical equipment is necessary to maintain the performance of the equipment. For example, a laboratory technician periodically replenishes or replaces reagents used in the medical equipment, and replaces or cleans the equipment used in the medical equipment. When maintenance work becomes necessary, the medical equipment notifies the technician's operating unit PC that maintenance work is necessary. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2013 / 065528 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 discloses an automatic analysis system that includes an analysis device that analyzes samples, a processing device that performs pre-processing of the samples, and a management device that manages each device. The management device of this automatic analysis system includes an abnormality detection means that detects an alarm generated in the analysis device or processing device, and an abnormality notification means that notifies an operator of an alarm detected by the abnormality detection means. The management device then registers a responder, which is an operator who responded to the alarm, and shares information about who responded to the alarm with other operators.

[0005] However, in order to prevent medical equipment from being stopped due to running out of reagents or maintenance, the technicians who operate the medical equipment are required to perform maintenance of the medical equipment and replace or replenish reagents on their own initiative, regardless of the equipment's alarm. In addition, it is difficult for inexperienced technicians to determine what work should be performed without an alarm being generated. In Patent Document 1, although the operator (technologist) can deal with an alarm notified by the abnormality notification means, it is difficult for the operator to perform work such as running out of reagents or maintenance on his or her own initiative. Furthermore, since the technicians were not shared with each other regarding their intention to perform a task, there was a problem of the task being performed multiple times.

[0006] The present invention proposes a technique for providing a list of tasks that are recommended to be performed voluntarily on medical equipment regardless of an alarm from the device, and for technicians to share their intention to be in charge of the tasks. [Means for solving the problem]

[0007] The present invention includes multiple means for solving the above-mentioned problems. One example is a work support system that is communicatively connected to a medical device and a plurality of information processing devices, and includes: a list creation unit that creates a task list including one or more tasks that are recommended to be performed by the medical device; a list sending unit that transmits the task list created by the list creation unit to the plurality of information processing devices; an intention receiving unit that receives information indicating an intention to take charge of a task in the task list from one of the plurality of information processing devices; and an intention sending unit that transmits information indicating that an intention has been expressed to take charge of a task in the task list to at least an information processing device other than the information processing device that transmitted the information indicating the intention. Effect of the Invention

[0008] According to the present invention, a medical technician can check a list of tasks that are recommended to be performed on the medical device voluntarily without being affected by an alarm from the device, and the medical technicians can share their intention to be in charge of the tasks. Problems, configurations, and effects other than those described above will be made clear by the following description of the embodiments. [Brief description of the drawings]

The list transmission unit 114 transmits the task list created by the list creation unit 113 to each terminal 300 connected to the task support system 100. The list screen information is data in HTML format, and is data for displaying the task list on the display unit 306 of the terminal 300. The list screen information is created by the list creation unit 113 functioning as a screen information generation unit. The web browser of the terminal 300 that receives the list screen information displays the task list including the reagent replacement task and the maintenance task on the display unit 306.

[0031] On the ToDo list screen 900 (see FIG. 9 ) displayed on the display unit 306 of the terminal 300, the user of the terminal 300 can express an intention to take charge of a task in the task list. The intention receiving unit 116 receives information indicating an intention to take charge of a task in the task list from the terminal 300. In the first embodiment, the intention to take charge of a task is called a "raise of hand", and the information indicating the intention is called "raise of hand data". The hand raising data includes the time when the intention was expressed, information for identifying the person who expressed the intention, the task that was the subject of the intention, and the type of data (raise of hand). The intention sending unit 117 transmits information indicating that an intention to take charge of a task in the task list ("raise of hand") has been expressed to each terminal 300. On the terminal 300, the ToDo list screen 900 is displayed so that it is possible to know who has expressed an intention to take charge of which task.

[0032] On the ToDo list screen 900 displayed on the display unit 306 of the terminal 300, the user of the terminal 300 can notify the work support system 100 that a task in the work list has been completed. In addition, the medical device 200 can detect that a task has been completed using a sensor or the like, and the medical device 200 can notify the work support system 100 that a task has been completed. For example, the medical device 200 can detect the replacement of a reagent using a sensor or the like. The completion information receiving unit 118 receives information indicating the completion of a task (hereinafter referred to as "completion data") from the terminal 300 or the medical device 200. The completion data includes the time when the task was completed, information for identifying the person who completed the task, the completed task, and the type of data (completion). The completion information transmitting unit 119 transmits information indicating that a task in the work list has been completed to each terminal 300. On the terminal 300, a completed ToDo list tab 902 is displayed so that it is possible to know who completed which task.

[0033] In the completed ToDo list tab 902 displayed on the display unit 306 of the terminal 300, the user of the terminal 300 can express support for the person in charge of the completed work. In the first embodiment, the expression of support for the person in charge of the completed work is called "Like", and information indicating the expression of support is called "Like data". The Like data includes the time when the expression of support was made, information for identifying the person who expressed the support, the work for which the expression of support was made, and the type of data (Like). The support expression sending unit 121 transmits to each terminal 300 information indicating that the expression of support has been made for the person in charge of the completed work. In the terminal 300, the completed ToDo list tab 902 is displayed so that it is possible to know who has expressed support for which person in charge of which work. The user of the terminal 300 can express support not only for the person in charge of the completed work, but also for the person in charge of the work for which the intention has been expressed.

[0034] The task adding unit 122 adds a task that is recommended to be performed to the task list in accordance with an instruction from the user of the terminal 300. The task added by the task adding unit 122 may be a task related to the medical devices 200, or may be a task unrelated to the medical devices 200. For example, the task adding unit 122 may add a task of removing dust between multiple medical devices 200 to the task list as a task related to the medical devices 200. The task adding unit 122 may also add a task of throwing away empty cardboard boxes in a stockyard to the task list as a task unrelated to the medical devices 200.

[0035] The message sending unit 123 notifies the terminal 300 of a message by e-mail, pop-up, or the like. The message sending unit 123 can also notify a message to a terminal registered in advance, such as a private terminal of a medical technician, in addition to the terminal 300. When an intention to take charge of a task is expressed, the message sending unit 123 transmits the intention to take charge of the task to each terminal 300 or a terminal registered in advance by e-mail or the like. When the task is completed, the message sending unit 123 transmits the intention to take charge of the task to each terminal 300 or a terminal registered in advance by e-mail or the like. When an indication of support is made for a person in charge of a completed task or an indicated intention to take charge of the task, the message sending unit 123 transmits the indication of support to each terminal 300 or a terminal registered in advance by e-mail or the like.

[0036] The upper limit setting unit 124 sets an upper limit on the number of workers for a task. The upper limit on the number of workers may be one or more. By setting an upper limit on the number of workers for a task, it is possible to prevent workers exceeding the upper limit from expressing their intention to take on the task.

[0037] On the ToDo list screen 900 displayed on the display unit 306 of the terminal 300, a user who has expressed an intention to take charge of a task can cancel the intention for the task on the terminal 300. The intention cancellation unit 125 receives information indicating the cancellation of the intention from the terminal 300. The intention cancellation unit 125 cancels the intention when a predetermined condition is satisfied. The predetermined condition is when a predetermined time has elapsed since the intention was expressed or when the user who expressed the intention cancels the intention by himself / herself. The intention may be cancelled only by the user who expressed the intention, or all users may be able to cancel the intention, or only the administrator may be able to cancel the intention.

[0038] The work procedure transmission unit 126 transmits information (work procedure information) indicating the work procedure of a work selected in the work list to a medical technician or the like who will perform the work. The work procedure transmission unit 126 transmits information indicating operation procedures such as videos and animations to a terminal 300 used by the medical technician in response to a request from the medical technician.

[0040] FIG. 7 is a table for linking and managing the ID, password, and role of each user. The management table 140 shown in FIG. 7 may be recorded in the auxiliary storage device 104 of the work support system 100, or may be recorded in an external device such as a directory server communicably connected to the work support system 100. In order to use the Web application 104a of the work support system 100, it is necessary to log in to the work support system 100. A user who uses a terminal 300 inputs an ID and a password on the terminal 300. The work support system 100 that receives the ID and password from the terminal 300 refers to the management table 140 in FIG. 7 and performs user authentication. If the user authentication is successful, the user is logged in to the work support system 100 and is able to use the Web application 104a.

[0041] Roles are assigned to users in the management table 140. For example, the roles of users A, C, and E are veteran engineers, the roles of users B and C are new engineers, and the roles of users F and G are managers. A veteran engineer is assumed to be, for example, an engineer in a position to guide newcomers. A role is assigned to a system user, and the user is given a task difficulty and rights and authority. The task difficulty includes the work history of a newcomer or a veteran, and the strengths and weaknesses of the task. Depending on the assigned role, when a new engineer raises his or her hand for a task with a high level of difficulty, a notification is sent to an engineer in a position to guide newcomers and a veteran engineer, and it is also possible to encourage two or more people to work together to advance the task. In addition, a manager such as a chief engineer can leave a log of the task content, time, and approver name as an approval record by pressing "Like".

The processor 301 is, for example, a central processing unit (CPU), a digital signal processor (DSP), or an application specific integrated circuit (ASIC). The processor 301 deploys a program stored in the auxiliary storage device 304 in an executable manner in a working area of ​​the main storage device 303. The main storage device 303 stores the program executed by the processor 301, data processed by the processor, and the like. The main storage device 303 is, for example, a flash memory, a random access memory (RAM), a read only memory (ROM), and the like. The auxiliary storage device 304 stores various programs and various data. The auxiliary storage device 304 stores, for example, an operating system (OS), various programs including a web browser, various tables, and the like. The auxiliary storage device 304 is a silicon disk including a non-volatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a solid state drive device, a hard disk drive (HDD, Hard Disk Drive) device, or the like.

[0045] The communication I / F 302 is an interface for connecting the terminal 300 to the task support system 100 via a network so that the terminal 300 can communicate with the task support system 100. The input / output I / F 305 accepts operation instructions and the like from a user of the terminal 300 who operates an input device connected to the input / output I / F 305. Examples of the input device include a keyboard, a touch panel, a mouse, and a microphone. In addition, the input / output I / F 305 can be connected to a display device such as an LCD, an EL (Electroluminescence) panel, or an organic EL panel, and an output device such as a printer or a speaker. The input / output I / F 305 outputs data and information processed by the processor 301 and data and information stored in the main storage device 303 or the auxiliary storage device 304 to an output device (for example, a display unit 306, a printing device not shown).

[0046] (ToDo list screen) 9 to 12 show ToDo list screens displayed on the display unit of the terminal. The Web browser of the terminal 300 displays a ToDo list screen 900 provided by the Web application 104a of the work support system 100 on the display unit 306. The ToDo list screen 900 has a ToDo list tab 901 that displays a list of ToDos that have not been completed, and a completed ToDo list tab 902 that displays a list of ToDos that have been completed. The ToDo list tab 901 has a display area 910 that displays one or more tasks 911 to 914, an order selection area 920 for selecting the display order of the tasks in the display area 910, and a filter area 930 for filtering the tasks to be displayed in the display area 910.

[0047] In the display area 910, a task 911 that is past its deadline, tasks 912 and 913 that are recommended to be performed today, and a task 914 that is recommended to be performed within four days are displayed. By moving the scroll bar 915, tasks that can be performed five days or later are displayed. Each task 911 to 914 has a cell A that displays the content of the task, the name of the medical device 200 that is the target of the task, and the deadline for performing the task, a cell B that displays the person in charge, and a completion button C. For example, the task 911 indicates a task to replace two bottles of AAA reagent, 15 bottles of BBB reagent, five bottles of CCC reagent, three bottles of DDD reagent, and five bottles of EEE reagent in the first medical device 200 by 17:00 on June 10, 2021. The person in charge of the task 911 has not yet been decided, and the user selects the raise hand button D in cell B, and the selected user becomes the person in charge. The selection includes the selection of the raise hand button D by a touch operation detected by a touch sensor mounted on the display unit 306 of the terminal 300, the selection of the raise hand button D detected by a pointing device such as a mouse connected to the terminal 300, etc. When the raise hand button D is selected, hand raising data is transmitted from the terminal 300 to the work support system 100.

[0048] In task 912, logged-in user A has selected raise hand button D, and so A is the person in charge. And the raise hand button D is active. As in task 913, multiple people (A, B, C, D, and others) may be the people in charge. Note that all the people in charge can be displayed by the user selecting cell B of task 913. The done button C is a button for marking the task as completed. The person in charge who performed the task can change the status of the task to "completed" by selecting the done button C. When the done button C is selected, completion data is sent from the terminal 300 to the task support system 100.

[0049] The order selection area 920 is an area for selecting the display order of tasks to be displayed in the display area 910. In Fig. 9, the display order 921 is set to "by deadline", so tasks are displayed in the order of the nearest deadline in the display area 910. In addition, the order selection area 920 includes an add ToDo button 922 for adding a task.

[0050] When the user selects the Add ToDo button 922, a new task can be added. The task added with the Add ToDo button 922 is called an arbitrarily created ToDo task. FIG. 10 shows a screen displayed when the Add ToDo button 922 is selected. The screen in FIG. 10 includes a pop-up 923 for creating an arbitrarily created ToDo task. In the pop-up 923, the creator of the arbitrarily created ToDo task inputs a recommended deadline for performing the task to be added, the creator of the task to be added, the category of the task to be added, the priority of the task to be added, the content of the task to be added, and the like. By inputting and adding to each item in the pop-up 923, the arbitrarily created ToDo task is added to the task list. The content input in the pop-up 923 is sent to the task support system 100, and the task adding unit 122 of the task support system 100 adds the arbitrarily created ToDo task to the task list.

[0051] The filter area 930 is an area for filtering the tasks displayed in the display area 910. The user can filter the tasks displayed in the display area 910 by deadline by checking a check box related to the deadline in the filter area 930 (by the end of today / within 4 days / after 5 days). The user can filter the tasks displayed in the display area 910 by category by checking a check box related to the category in the filter area 930 (reagent replacement / maintenance / other). The user can filter the tasks displayed in the display area 910 by name of the medical device 200 by selecting the device No. (No. 1 / No. 2 / No. 3, etc.) in the filter area 930. The user can filter the tasks displayed in the display area 910 by type by selecting the type of task (all ToDo / device creation ToDo / custom created ToDo) in the filter area 930. Custom created ToDo tasks are tasks added in the popup 923 in FIG. 10, and device creation ToDo tasks are tasks created by the work support system 100. The user can also filter the tasks displayed in the display area 910 by task owner by selecting task owner (task owner / all) in the filter area 930.

[0052] 11 is a screen for communicating details of the work procedure of a task to a laboratory technician. For example, when cell A of a task 911 related to reagent replacement is selected, a pop-up 924 for communicating details of the reagent replacement method to the laboratory technician is displayed on the display unit 306 of the terminal 300. This pop-up 924 includes a video area 925 that displays a video or animation of the reagent replacement procedure, and a text area 926 that displays each step of the reagent replacement in text format. When a play button 927 in the video area 925 is selected, a video or animation showing the reagent replacement procedure is played.

[0053] 12, the completed ToDo list tab 902 has a display area 950 that displays completed tasks 951-955, an order selection area 960 for selecting the display order of the tasks, and a filter area 970 for filtering the tasks displayed in the display area 950. The order selection area 960 and the filter area 970 have the same functions as the order selection area 920 and the filter area 930 described above, respectively, and therefore their description will be omitted.

[0054] In the display area 950, one or more completed tasks 951 to 955 are displayed in a grayed-out state. By moving the scroll bar 915, other completed tasks are displayed. Each of the tasks 951 and 955 is a completed task, and the task status is "completed". By selecting the completion button C, the task status becomes "completed". And, a like button E is displayed for the task with the "completed" status. The like button E is displayed to show support for the person in charge of the completed task. When the like button E is selected, like data is transmitted to the task support system 100. The support reception unit 120 of the task support system 100 receives the like data.

[0055] The status of each of the tasks 952 to 954 is "Completed but canceled." By selecting the Complete button C, the status of each of the tasks 952 to 954 becomes "Completed." However, by selecting the Complete button F, the status of each of the tasks 952 to 954 is changed from "Completed" to "Completed but canceled."

[0056] (Medical system operation) FIG. 13 is a data flow diagram for explaining a work support method by the work support system. The work support method will be explained with reference to the data flow diagram of FIG. 13. Each medical device 200 transmits data 240 (FIG. 3(a)) on the remaining amount of consumables to the work support system 100 periodically or in response to a request from the work support system 100 (S101). The work support system 100 executes a Web application 104a. The list creation unit 113 of the work support system 100 creates a reagent replacement task as a task recommended to be performed by the medical device 200 based on the data 240 on the remaining amount of consumables received from the medical device 200 (S102). In addition, the list creation unit 113 creates a maintenance task related to the maintenance of one or more medical devices 200 as a task recommended to be performed by the medical device 200 (S103). Then, the list creation unit 113 distributes a task list in which one or more reagent replacement tasks and maintenance tasks are listed to each terminal 300 (S104). The terminal 300 that receives the task list displays a ToDo list screen 900 on the display unit 306 (S105).

[0057] On the terminal 300 displaying the ToDo list screen 900, the content of the manually created ToDo task is input using the Add ToDo button 922 and the popup 923 (S106). The terminal 300 transmits the content of the manually created ToDo task (the deadline for which it is recommended to perform the task, the creator who created the task, the task category, the task priority, and the task content) to the work support system 100 (S107). The work support system 100 adds the manually created ToDo task to the task list based on the received content of the manually created ToDo task, and updates it (S108). Then, the work support system 100 distributes the task list including the added task to each terminal 300 (S109).

[0058] When the hand-raising button D is selected on the terminal 300 on which the ToDo list tab 901 is displayed (S110), the hand-raising button D becomes active, and the name of the person who selected the hand-raising button D is displayed next to the hand-raising button D. When the hand-raising button D is selected on the terminal 300, hand-raising data is transmitted from the terminal 300 to the work support system 100 (S111). The hand-raising data includes the time when the hand-raising button D was selected, information for identifying the person who selected the hand-raising button D, the task corresponding to the hand-raising button D, and the type of the selected button. Based on the received hand-raising data, the work support system 100 distributes a list of tasks including tasks linked to the active hand-raising button D and the name of the person in charge, and displays the list on the display unit 306 of each terminal 300. In addition, the message transmission unit 123 of the work support system 100 transmits information indicating that the hand-raising button D has been selected to other terminals 300 registered in advance by e-mail or the like (S112).

[0059] When the Complete button C is selected on the terminal 300 on which the ToDo list tab 901 is displayed (S113a), the status of the task corresponding to the Complete button C becomes “Completed”, and the task is deleted from the ToDo list tab 901. Then, the task deleted from the ToDo list tab 901 is added to the Completed ToDo list tab 902. When the Complete button C is selected on the terminal 300, completion data is transmitted from the terminal 300 to the work support system 100 (S114a). The completion data includes the time when the Complete button C was selected, information for identifying the person who selected the Complete button C, the task corresponding to the Complete button C, and the type of the selected button. Based on the received completion data, the work support system 100 deletes the completed task from the ToDo list tab 901 and adds the completed task to the Completed ToDo list tab 902. Then, a task list including the updated ToDo list tab 901 and the Completed ToDo list tab 902 is distributed and displayed on the display unit 306 of each terminal 300.

[0060] Furthermore, when the medical device 200 detects the completion of the reagent replacement work (S113b), completion data including the time the work was completed, the completed work, etc. is transmitted from the medical device 200 to the work support system 100 (S114b). Based on the received completion data, the work support system 100 deletes the completed work from the ToDo list tab 901 and adds the completed work to the Completed ToDo list tab 902. Then, the work support system 100 distributes a work list including the updated ToDo list tab 901 and Completed ToDo list tab 902, and causes it to be displayed on the display unit 306 of each terminal 300.

[0061] When the Completed button F is selected on the terminal 300 displaying the Completed ToDo list tab 902 (S115), the status of the selected task becomes “Completed Cancelled”, and the task is added to the ToDo list tab 901. When the Completed button F is selected on the terminal 300, completion cancellation data is sent to the work support system 100 (S116). The completion cancellation data includes the time when the Completed button F was selected, information for identifying the person who selected the Completed button F, the task corresponding to the Completed button F, and the type of button selected. The work support system 100 adds the completed task to the ToDo list tab 901 based on the received completion cancellation data. Then, the work support system 100 distributes the task list including the updated ToDo list tab 901, and causes it to be displayed on the display unit 306 of each terminal 300.

[0062] When the Like button E is selected on the terminal 300 displaying the completed ToDo list tab 902 (S117), Like data is transmitted from the terminal 300 to the work support system 100 (S118). The Like data includes the time when the Like button E was selected, information for identifying the person who selected the Like button E, the task corresponding to the Like button E, and the type of button selected. Based on the Like data, the work support system 100 distributes a task list including the task for which the Like button E has become active, and displays it on the display unit 306 of each terminal 300.

[0063] Furthermore, when an alarm occurs in the medical device 200, the medical device 200 transmits data 240 (FIG. 3(b)) related to the alarm to the work support system 100 (S119). Based on the data 240 related to the alarm transmitted from the medical device 200, the work support system 100 transmits to each terminal 300 a message that an alarm has occurred in the medical device 200 and details of the generated alarm (S120).

[0064] (Effects of Example 1) By the work support system 100 transmitting the work list to the terminal 300, the medical technician can view the work list including the work recommended to be performed by the medical device 200 before an alarm is generated in the medical device 200, and can voluntarily indicate his / her intention to take charge of the work in the work list. Furthermore, other medical technicians can recognize that the person in charge of the work has been decided on the ToDo list screen 900, so that the intention to take charge of the work can be shared among medical technicians. As a result, it is possible to prevent duplicate work from being performed on the work.

[0065] In addition, other laboratory technicians can recognize the name of the person in charge of the work for which the intention has been expressed on the ToDo list screen 900, and can therefore know who will be performing the work.

[0066] Since the laboratory technicians and the managers can see the tasks that have not been raised on the ToDo list screen 900, it is possible to prevent the omission of tasks. Furthermore, since the laboratory technicians and the managers can see the status of intentions expressed on the ToDo list screen 900, they can understand the progress of the entire task.

[0067] The ToDo list tab 901 displays a ToDo list of tasks that have not yet been performed, so that the medical technician can easily grasp only the tasks that are currently recommended to be performed.

[0068] Since the tasks displayed in the display area 910 can be filtered by the person in charge (person in charge / all) in the filter area 930, the technologist can easily grasp only the tasks for which he or she has expressed an intention.

[0069] By selecting "by deadline" in the display order 921 of the order selection area 920, the technician can view tasks sorted by deadline, which makes it easier to understand tasks that are recommended to be performed before holidays.

[0070] By checking the occurrence of an alarm and details of the alarm displayed on the terminal 300, the medical technician can grasp the details of the alarm that has occurred in the medical equipment 200.

[0071] The completed ToDo list tab 902 displays a list of completed tasks, allowing the technician to easily grasp the tasks that have been completed.

[0072] An optional ToDo task can be added to the task list by using the ToDo addition button 922 and popup 923 of the terminal 300 and the task adding unit 122 of the task support system 100. This allows the medical technician to remember to perform the added optional ToDo task.

[0073] The task support system 100 includes an upper limit setting unit 124, which can prevent more than the set number of workers from working on one task. This can prevent bias in the number of workers, such as distributing workers to each task.

[0074] The intention canceling section 125 of the work support system 100 can cancel the intention when the work for which the intention has been expressed is not completed no matter how long it is waited for, so that the intention of another technician in charge of the work for which the intention has been canceled can be expected to be expressed.

[0075] By displaying button E on the completed ToDo list tab 902, it is possible to convey gratitude to the laboratory technician who has completed the work as feedback to the technician. It is also possible to convey gratitude to the laboratory technician who has expressed an intention to take on the work as feedback. Furthermore, the like data can be used as a record of approval by a manager. For example, the log data 130 in FIG. 6 can be used as a record of approval by a manager.

[0076] Since the details of the work, such as the reagent replacement method, can be confirmed on the terminal 300 through videos, animations and text, even a novice technician can carry out the work while looking at the videos, animations and text.

[0077] <Example 2> The work support system of the second embodiment will be described with reference to FIG. 14. The description of the same parts as those of the first embodiment will be omitted. FIG. 14 shows a screen 1400 provided to the terminal 300 by the work support system 100 of the second embodiment, and the screen 1400 displays an ASSIGN button G for assigning a person in charge. The ASSIGN button G is displayed for a task to which no person in charge is assigned. When the user of the terminal 300 selects the ASSIGN button G, a list 928 of users is displayed as candidates for the person in charge of the task. The person in charge of the task can be assigned by checking a check box next to the user name displayed in the list 928. The assignment unit 128 of the work support system 100 receives information related to the person in charge selected in the list 928 and assigns the selected person in charge to the task. The person in charge may be one person or multiple people. Also, the list 928 may display a recommended number of workers. Also, the authority to assign a person in charge may be given to the role of FIG. 7. For example, if the role is a manager, the assignment of a person in charge is permitted, but if the role is a veteran engineer or a new engineer, the assignment of a person in charge is prohibited. In the second embodiment, the ASSIGN button G is displayed, but the ASSIGN button G may not be displayed and a hand icon in Fig. 14 may have the function of the ASSIGN button G. In this case, the display form (e.g., color) of the hand icon may be changed before and after the person in charge is assigned.

[0078] Since the ASSIGN button G can be used to assign a person in charge of a task, the technician who is best suited for the task can be assigned as the person in charge. In addition, the technician's workload can be taken into consideration when assigning the most appropriate technician as the person in charge.

[0079] <Example 3> The task support system of the third embodiment will be described with reference to FIG. 15. The description of the same parts as those of the first embodiment will be omitted. FIG. 15 shows a screen 1500 provided to the terminal 300 by the task support system 100 of the third embodiment, and the screen 1500 displays a message 929 recommending other tasks related to the task that has been raised to the user who raised his / her hand. For example, when person A raises his / her hand for task 912, a message 929 recommending task 914 to be performed at the same time is displayed on the display unit 306 of the terminal 300. Tasks 912 and 914 are registered in advance as related tasks, and when a hand is raised for task 912, the recommendation unit 127 of the task support system 100 recommends task 914 to the user as a task related to task 912.

[0080] By the recommendation unit 127 recommending other tasks related to the task that has been raised, it is possible to recommend to the technician who raised his / her hand tasks that would be efficient if performed simultaneously with the task that has been raised or tasks that can be performed in a location that is physically close to the task that has been raised.

[0081] <Example 4> The work support system of the fourth embodiment will be described with reference to FIG. 16. The description of the same parts as those of the first embodiment will be omitted. FIG. 16 shows a screen 1600 provided to the terminal 300 by the work support system 100 of the fourth embodiment, and the screen 1600 displays a delete button H and an edit button I for deleting a work. When the delete button H for the work 913 is selected by the user, the work 913 is deleted. The edit / delete unit 129 of the work support system 100 deletes or edits the work according to the operation of the delete button H or the edit button I. In addition, the authority to delete a work may be given to the role of FIG. 7. For example, if the role is a manager or a veteran engineer, the deletion of the work is permitted, but if the role is a new engineer, the deletion of the work is prohibited.

[0082] When the edit button I for the task 913 is selected by the user, it is possible to edit the contents of the task 913. For example, when the edit button I is selected, a pop-up 923 in Fig. 10 is displayed, and in the pop-up 923, it is possible to edit the deadline of the task, the creator of the task, the task category, the task priority, the task contents, etc.

[0083] <Example 5> The work support system of the fifth embodiment will be described with reference to FIG. 17. The description of the same parts as those of the first embodiment will be omitted. FIG. 17 shows a screen 1700 provided to the terminal 300 by the work support system 100 of the fifth embodiment, which is a screen 1700 for confirming details of the remaining amount of the consumable. The detailed screen information is data for displaying details of the remaining amount of the consumable on the display unit 306 of the terminal 300. The detailed screen information is created by the list creation unit 113 functioning as a screen information generation unit. The web browser of the terminal 300 that has received the detailed screen information displays the screen 1700 showing details of the remaining amount of the consumable on the display unit 306. The laboratory technician can determine whether or not to perform the work 912, the timing of performing the work, and the like by viewing the screen 1700. By changing the predicted date on this screen 1700, the predicted remaining amount of the consumable on the changed predicted date can be confirmed.

[0084] In the fifth embodiment, the user of the terminal 300 can indicate his / her intention to take charge of the task 912 on the screen 1700 for confirming details of the remaining amount of the consumable. That is, in the fifth embodiment, the user can indicate his / her intention to take charge of the task on the ToDo list screen 900, and can also indicate his / her intention to take charge of the task on the screen 1700 for confirming the predicted remaining amount of the consumable. A raise hand button D is displayed on the screen 1700, and the user can indicate his / her intention to take charge of the task 912 on the screen 1700. Note that in the present invention, it is sufficient that the user can indicate his / her intention on at least one of the ToDo list screen 900 and the screen 1700 for confirming the predicted remaining amount of the consumable.
