[0003] [Patent Document 1] JP 2017-120620 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in a hospital, for example, a number of transmitters that are considered necessary are arranged for each ward. In addition, in a hospital, for example, one or more management devices such as a central monitor are installed for each ward. A user such as a medical staff sets a channel for each transmitter in the management device installed in the hospital (for example, each ward). The transmitter is attached to a subject for use, but since the number of subjects is not constant, for example, some wards may have a shortage of transmitters. In this case, transmitters may be temporarily borrowed and lent between wards. When it is desired to return the transmitter to its original arrangement after lending and borrowing a transmitter, a medical staff may go around each ward and check whether the channel of each transmitter is registered in a management device other than the management device in which it was originally registered, but depending on the number and size of the wards, this may require a lot of work. For this reason, there is a need to easily know whether the channel of a transmitter is registered in a management device other than the management device in which it was originally registered.

[0005] The present disclosure aims to provide an information processing device, an information processing method, a computer program, and a non-transitory computer-readable medium that can easily determine whether a transmitter channel has been registered with a management device other than the management device to which it was originally registered. [Means for solving the problem]

[0006] In order to achieve the above object, an information processing device according to one aspect includes: At least one processor; A memory that stores at least one instruction executable by the processor, When at least one of the instructions is executed by the processor, the information processing device: Obtaining initial channel information indicating a channel of at least one transmitter registered in a management device at an initial setting time and subsequent channel information including current channel information indicating a channel of the transmitter currently registered in the management device from a plurality of the management devices; Based on the initial channel information and the subsequent channel information, difference / similar information is generated that indicates differences / similarities at least between the management device in which the channel is currently registered and the management device in which the channel was registered at the time of the initial setting.

[0007] In addition, an information processing method according to one aspect for achieving the above object includes: An information processing method executed by an information processing device, acquiring, from a plurality of said management devices, initial channel information indicating a channel of at least one transmitter registered in said management device at an initial setting time, and subsequent channel information including current channel information indicating a channel of said transmitter currently registered in said management device; The method includes a step of generating, based on the initial channel information and the subsequent channel information, difference / similar information indicating differences / similarities between the management device in which the channel is registered at least at the present time and the management device in which the channel was registered at the time of the initial setup.

[0008] In addition, a computer program according to one aspect for achieving the above object comprises: A computer program comprising at least one instruction for execution by a processor of an information processing device, At least one of the instructions, when executed by the processor, causes the information processing device to: obtain, from a plurality of the management devices, initial channel information indicating a channel of at least one transmitter registered in the management device at an initial setting time, and subsequent channel information including current channel information indicating a channel of the transmitter currently registered in the management device; Based on the initial channel information and the subsequent channel information, difference / similar information is generated that indicates differences / similarities at least between the management device in which the channel is currently registered and the management device in which the channel was registered at the time of the initial setting.

[0009] In addition, a non-transitory computer-readable medium according to one embodiment for achieving the above object includes: The above computer program is stored.

[0010] According to the information processing device of the above configuration, for each of the channels of the multiple transmitters registered in the multiple management devices, difference / same information is generated based on the initial channel information and the subsequent channel information. The difference / same information is information indicating the difference / same between the management device in which the channel of the transmitter is registered at least at the current time and the management device in which the channel of the transmitter was registered at the time of initial setting. By using the difference / same information, the user can easily know the channel of the transmitter currently registered in a management device different from the management device in which the channel of the transmitter was registered at the time of initial setting. Therefore, according to the information processing device of the above configuration, the user can easily know whether the transmitter is registered in a management device other than the management device in which the transmitter was initially registered. In addition, the information processing method, the computer program, and the non-transitory computer-readable medium of the above configuration can also achieve the same effect.

[0013] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings.

[0014] (Overall composition) The information processing system 1 of the present embodiment will be described with reference to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram illustrating the information processing system 1 according to an embodiment of the present disclosure. The information processing system 1 is used in, for example, a medical facility such as a hospital. In this embodiment, the information processing system 1 is used in X Hospital. As illustrated in FIG. 1, the information processing system 1 includes a plurality of management devices 10, an information processing device 20, and a user terminal device 30. In this embodiment, X Hospital includes Ward A, Ward B, and Ward C. A management device 10A is installed in Ward A, a management device 10B is installed in Ward B, and a management device 10C is installed in Ward C. In this embodiment, one management device 10 is installed in each ward, but there may be a ward in which multiple management devices 10 are installed.

[0015] At least one bed is provided in each ward. In this embodiment, eight beds are provided in ward A, six beds in ward B, and eight beds in ward C (see FIG. 4). In this embodiment, identification information for identifying the beds provided in the wards is registered in the management device 10. In this embodiment, BED IDs are registered in the management device 10 as identification information. In this embodiment, the BED IDs can be used as location information indicating the locations where the beds are provided in the wards. Furthermore, the BED IDs related to the beds used by the subjects can be used as subject identification information for identifying the subject using the beds.

[0016] At least one transmitter 40 is arranged in each ward. In this embodiment, one transmitter 40 is used in each bed installed in each ward. In this embodiment, the transmitter 40 can be used in the ward by registering channel information indicating the channel of the transmitter 40 in the management device 10 installed in the ward in which the bed in which the transmitter 40 is used is arranged. For example, when the transmitter 40A is used in a certain bed arranged in the A ward, the transmitter 40A can be used in the A ward by registering channel information indicating the channel of the transmitter 40A in the management device 10A. Note that each transmitter 40 is assigned a different channel, and it is assumed that the correspondence between the channel information and the transmitter is not changed. For this reason, for example, when the transmitter 40A used in the A ward is to be used in the B ward, the channel information of the transmitter 40A needs to be registered in the management device 10B in the B ward.

[0017] In this embodiment, channel information indicating the channel of at least one transmitter 40 registered in the management device 10 at the time of initial setting is referred to as initial channel information. The time of initial setting is the time when the channel information of the transmitter 40 is first registered in the management device 10 installed in any one of Wards A to C of X Hospital. In this embodiment, channel information indicating the channel of the transmitter 40 registered in the management device 10 at a time after the time of initial setting is referred to as post-event channel information. In this specification, the term "time" may refer to a specific time or a period such as one day, one month, or one year. The post-event channel information includes current channel information indicating the channel of the transmitter 40 registered in the management device 10 at the current time. The current time is the time when the information processing device 20 executes an information processing method described later.

[0018] The post-event channel information may include not only the current channel information but also intermediate channel information indicating the channel of the transmitter 40 registered in the management device 10 at at least one intermediate point in time that is after the initial setting point in time and before the current point in time. Therefore, the post-event channel information may include intermediate channel information at a plurality of intermediate points in time that are different from each other. In this embodiment, the post-event channel information includes time-point identification information indicating at which point in time the post-event channel information is.

[0019] The transmitter 40 is electrically connected, by wire or wirelessly, to a sensor (not shown) that measures biological information of the subject. The transmitter 40 is configured to receive the biological information from the sensor. The transmitter 40 is connected, by wire or wirelessly, to the management device 10 so as to be able to communicate with the management device 10. The transmitter 40 transmits various information such as the biological information to the management device 10.

[0020] The management device 10 is, for example, a central monitor. The management device 10 is communicably connected to the information processing device 20 and the transmitter 40 by wire or wirelessly. The management device 10 includes an input / output interface 11, an input unit 12, a storage device 13, and a control unit 14. These are communicably connected to each other via a bus 15.

[0021] The input / output interface 11 functions as an interface between the management device 10 and the information processing device 20. The input / output interface 31 also functions as an interface between the management device 10 and the transmitter 40.

[0022] The input unit 12 is configured to accept an input operation of a user who operates the management device 10. The input unit 12 is, for example, a touch panel arranged overlaid on the display unit of the management device 10, an operation button attached to the housing of the management device 10, or the like. The input unit 12 accepts an input operation for registering various information such as initial channel information, post-channel information, and identification information in the management device 10. For example, when the initial channel information or post-channel information is input to the input unit 12, the input unit 12 transmits the input initial channel information or post-channel information to the storage device 13.

[0023] The storage device 13 is configured to store, for example, various data. The storage device 13 is, for example, a storage device such as a hard disk drive (HDD), a solid state drive (SSD), a flash memory, etc. The storage device 13 stores various information such as, for example, initial channel information, post-channel information, and identification information.

[0024] The control unit 14 includes a memory and a processor as a hardware configuration. The memory is, for example, a ROM (Read Only Memory) in which various computer programs and the like are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs and the like executed by the processor are stored. The processor is, for example, a CPU (Central Processing Unit) configured to develop a computer program designated from various computer programs incorporated in the ROM on the RAM and execute various processes in cooperation with the RAM. The control unit 14 transmits various information such as initial channel information, post-channel information, and identification information to the information processing device 20 based on, for example, an instruction signal received from the information processing device 20 described later.

[0025] The information processing device 20 is, for example, a server such as a cloud server or an edge server. A cloud server is a server provided via the Internet. An edge server is a server provided via a network (for example, a local area network (LAN)) in an area closer to the user than the Internet. The information processing device 20 includes an input / output interface 21 and a control unit 22. These are connected to each other via a bus 23 so as to be able to communicate with each other.

[0026] The input / output interface 21 functions as an interface between the management device 10 and the information processing device 20. The input / output interface 21 also functions as an interface between the information processing device 20 and the user terminal device 30.

[0027] The control unit 22 may have the same hardware configuration as the control unit 14. The control unit 22 includes at least one processor 221 and a memory 222 that stores at least one instruction executable by the processor 221.

[0028] In this embodiment, a computer-readable medium may be used. The computer-readable medium refers to any type of physical memory (RAM, ROM, etc.) that can store information or data that can be read by a processor. The computer-readable medium may store instructions for execution by one or more processors. The term "computer-readable medium" includes tangible items and excludes carrier waves and transitory signals (i.e., non-transitory). Non-transitory computer-readable media include, for example, magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), and flash ROMs).

[0029] The control unit 22 generates an instruction signal for acquiring various information such as initial channel information, subsequent channel information, and identification information from the multiple management devices 10, for example, based on a request signal received from a user terminal device 30 described later. The control unit 22 acquires various information from the multiple management devices 10 by transmitting the instruction signal to the multiple management devices 10.

[0030] Based on the acquired initial channel information and subsequent channel information, the control unit 22 generates similarity / difference information indicating differences between at least the management device 10 in which the channel of the transmitter 40 is currently registered and the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. Note that the control unit 22 may generate similarity / difference information for each position in the ward based on the initial channel information, subsequent channel information, and identification information (position information).

[0031] The control unit 22 may acquire channel identification information for identifying at least one of the channels of the transmitters 40 registered in the management devices 10. For example, when a medical professional such as a clinical engineer or a nurse inputs a channel of at least one of the transmitters 40 via an operation unit 32 of a user terminal device 30 described later, the user terminal device 30 generates channel identification information based on the input channel. The user terminal device 30 transmits the generated channel identification information to the information processing device 20. In this manner, the control unit 22 of the information processing device 20 acquires the channel identification information. However, when the information processing device 20 includes an input unit for receiving input by a user such as a medical professional, the control unit 22 may acquire the channel identification information by directly inputting the channel of at least one of the transmitters 40 into the input unit of the information processing device 20 by the user. When the control unit 22 acquires the channel identification information, the control unit 22 generates difference / same information regarding the channel of the transmitter 40 identified by the channel identification information based on the initial channel information, the post-channel information, and the channel identification information.

[0032] The control unit 22 generates registration management device information including all management devices 10 in which the channel of the transmitter 40 is registered at least at the current time based on the subsequent channel information. Note that, for example, when the subsequent channel information includes current channel information and intermediate channel information, the registration management device information generated by the control unit 22 includes the current registration management device information and intermediate registration management device information. The current registration management device information is generated based on the current channel information. The intermediate registration management device information is generated based on the intermediate channel information. The current registration management device information is information indicating that it includes all management devices 10 in which the channel of the transmitter 40 is registered at the current time. The intermediate registration management device information is information indicating that it includes all management devices 10 in which the channel of the transmitter 40 was registered at the intermediate time.

[0033] For example, when the post-channel information includes time-point identification information, the control unit 22 generates registration management device information by linking it to the time-point identification information included in the post-channel information. In this case, the control unit 22 generates difference / same information based on the registration management device information generated by linking it to the time-point identification information.

[0034] Based on the registration management device information and the time point identification information, the control unit 22 generates the most recent registration information indicating the management device 10 in which the channel of the transmitter 40 was registered at the time point that is closest to the current time point among the times when the channel of the transmitter 40 was registered in the management device 10. For example, the control unit 22 determines whether the management device 10 in which the channel of the transmitter 40 is registered at each time point is the same as the management device 10 in which the channel was registered at the time of initial setup. Then, if there is a time point when the channel was registered in a management device 10 different from the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setup, the control unit 22 identifies the management device 10 in which the channel was registered at the time point that is closest to the current time point among the times, and generates the most recent registration information.

[0035] The control unit 22 generates display data based on at least the sameness / difference information. However, the control unit 22 may generate display data based on, for example, the sameness / difference information and at least one of the identification information, the registration management device information, and the most recently registered information. The control unit 22 transmits the generated display data to the user terminal device 30.

[0036] The user terminal device 30 is a device operated by a medical professional such as a clinical engineer or a nurse. The user terminal device 30 can be installed in a medical equipment safety management room, a nurse's station, or the like. The user terminal device 30 is an electronic device such as a desktop PC, a notebook PC, a tablet terminal, or a smartphone. The user terminal device 30 includes an input / output interface 31, an operation unit 32, and a display unit 33. These are connected to each other via a bus 34 so as to be able to communicate with each other.

[0037] The input / output interface 31 functions as an interface between the information processing device 20 and the user terminal device 30 .

[0038] The operation unit 32 is configured to receive an input operation of a user who operates the user terminal device 30 and generate a request signal corresponding to the input operation. The operation unit 32 is, for example, a touch panel arranged on top of the display unit 33, an operation button attached to the housing of the user terminal device 30, or the like. The operation unit 32 receives, for example, an input operation for acquiring display data and generates a request signal corresponding to the input operation. In this embodiment, the input operation for acquiring display data is an operation of selecting one search execution button from the four search execution buttons illustrated in FIG. 2. The generated request signal is transmitted to the information processing device 20 via the input / output interface 31. The information processing device 20 that receives the request signal generated by the operation unit 32 generates display data based on the request signal and transmits the generated display data to the user terminal device 30.

[0039] The search screen exemplified in Fig. 2 is displayed, for example, on display unit 33. In the state exemplified in Fig. 2, four search execution buttons, namely, overall current channel search, overall past channel search, current channel search, and past channel search, are displayed on display unit 33. The user selects one of the four search execution buttons corresponding to the search he or she wishes to execute. When the user selects one of the four search execution buttons corresponding to the search he or she wishes to execute, the search corresponding to the selected search execution button is executed.

[0040] The overall current channel search is a search executed when it is desired to check whether the management device 10 in which the channel of the transmitter 40 is currently registered for all channels of the transmitter 40 used in wards A to C is different from the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. The overall past channel search is a search executed when it is desired to check whether the management device 10 in which the channel of the transmitter 40 is currently registered and at least one intermediate time point for all channels of the transmitter 40 used in wards A to C is different from the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. The current channel search is a search executed when it is desired to check whether the management device 10 in which the specific channel is currently registered for a specific channel arbitrarily selected by the user is different from the management device 10 in which the specific channel was registered at the time of initial setting. A past channel search is a search that is performed when a user wishes to check whether the management device 10 in which a specific channel arbitrarily selected by the user is registered at the current time and at least one intermediate time point is different from the management device 10 in which the specific channel was registered at the time of initial setup.

[0041] The display unit 33 is, for example, a touch screen display such as a liquid crystal display, an organic EL display, etc. The display unit 33 is configured to display an image based on display data received from the information processing device 20, for example.

[0042] (First embodiment) Next, with reference to FIG. 3 to FIG. 6, an information processing method executed by the information processing device 20 in the first embodiment will be described. FIG. 3 is a flowchart diagram of the information processing method executed by the information processing device 20 in the first embodiment. FIG. 4 is a diagram showing an example of initial channel information. FIG. 5 is a diagram showing an example of intermediate channel information as of June 2022. FIG. 6 is a diagram showing an example of an image 100 based on display data. In this embodiment, the initial setting time is January 2022, and the current time is December 2022. In addition, it is assumed that a BED ID is registered as identification information in the management device 10. In addition, unless otherwise specified, in the following embodiments, the initial setting time is January 2022, the current time is December 2022, and the BED ID is registered in the management device 10. In addition, in this embodiment, it is assumed that an overall current channel search is performed.

[0043] In this embodiment, it is assumed that, as of June 2022, the transmitter 40H used in BED008 (see FIG. 4) in Ward A breaks down, and the transmitter 40J that was not used in Ward B as of June 2022 is lent to Ward A and started to be used in BED008. The channel assigned to the transmitter 40J is 4012. Therefore, in this embodiment, it is assumed that the transmitter 40J registered in the management device 10B installed in Ward B at the time of initial setting is lent to Ward A from June 2022 to the present. In other words, it is assumed that the channel of the transmitter 40J is registered in the management device 10A and the management device 10B from June 2022 to the present. It is assumed that the transmitter 40 has not been lent or borrowed since June 2022.

[0044] At the time of initial setup, a user such as a medical staff member inputs the initial channel information of the transmitter 40 to the input unit 12 of the management device 10 belonging to the ward in which the bed in which the transmitter 40 is used is located. The input unit 12 transmits the input initial channel information to the storage device 13. As a result, the initial channel information is registered in the management device 10 (STEP 01). The initial channel information is registered in association with the BED ID.

[0045] The initial channel information in this embodiment is as shown in FIG. 4. At the time of initial setting, transmitters 40A to 40H (see FIG. 1) are used for each bed in ward A (i.e., each bed from BED001 to BED008). For example, at the time of initial setting, transmitter 40A is used in BED001, and the channel of transmitter 40A is 4001. At the time of initial setting, transmitters 40I to 40N (see FIG. 1) are used for each bed in ward B (i.e., each bed from BED011 to BED016). At the time of initial setting, transmitters 40O to 40V (see FIG. 1) are used for each bed in ward C (i.e., each bed from BED021 to BED028).

[0046] Returning to FIG. 3, STEP02 will be described. In this embodiment, as of June 2022, the transmitter 40J that was registered in the management device 10B installed in the B ward at the time of initial setting is loaned to the A ward. For this reason, in order to enable the transmitter 40J to be used in the A ward, the user inputs intermediate channel information indicating that the channel of the transmitter 40J is registered in the management device 10A in the A ward as of June 2022 to the input unit 12 of the management device 10A. The intermediate channel information is registered in association with the BED ID. The intermediate channel information includes time-specific information indicating that the intermediate channel information is intermediate channel information as of June 2022. The input unit 12 of the management device 10A transmits the input intermediate channel information to the storage device 13 of the management device 10A. In this manner, the post-channel information (in this embodiment, the intermediate channel information as of June 2022) is registered in the management device 10A (STEP02). In addition, since the lending and borrowing of transmitters 40 between wards is often temporary, the user does not delete the channel information of transmitter 40J registered in management device 10B from management device 10B. In other words, the user does not perform any operation on management device 10B installed in Ward B.

[0047] The intermediate channel information registered in the management device 10A in STEP02 is as shown in Fig. 5. In STEP02, since no operation is performed on the management device 10B and the management device 10C, the channel information registered in the management device 10B and the management device 10C as of June 2022 is the same as the initial channel information shown in Fig. 4. As shown in Figs. 4 and 5, the channel associated with BED008 has been changed from 4008, which is the channel of the transmitter 40H, to 4012, which is the channel of the transmitter 40J.

[0048] Returning to Fig. 3, STEP 03 will be described. At this point in time, the user selects an overall current channel search from among the four search execution buttons (see Fig. 2) displayed on the display unit 33 of the user terminal device 30. When an overall current channel search is selected, the user terminal device 30 generates a request signal based on the selection and transmits the generated request signal to the information processing device 20. As a result, the information processing device 20 starts an overall current channel search (STEP 03).

[0049] The control unit 22 of the information processing device 20 generates an instruction signal for acquiring the initial channel information, the subsequent channel information, and the identification information from each of the management devices 10A to 10C based on the request signal received from the user terminal device 30. The control unit 22 acquires the initial channel information, the subsequent channel information, and the identification information from each of the management devices 10A to 10C by transmitting the instruction signal to each of the management devices 10A to 10C (STEP 04).

[0050] The control unit 22 generates currently registered management device information based on the current channel information included in the post-channel information (STEP 05). The currently registered management device information generated in this embodiment is information including all management devices 10 in which the channel of the transmitter 40 is currently registered. In this embodiment, as of June 2022, only the transmitter 40J has been lent and borrowed between Ward A and Ward B, and no other lent and borrowing of the transmitter 40 has occurred between wards. Therefore, at the present time, the channel associated with BED008 in Ward A is 4012, which is the channel of transmitter 40J. Therefore, the channel associated with BED008 in Ward A at the present time (i.e., 4012) is different from the channel associated with BED008 in Ward A at the time of initial setting (i.e., 4008). On the other hand, the channel associated with other beds other than BED008 at the present time is the same as the channel associated with the other beds at the time of initial setting. As described above, the channel information of transmitter 40J registered in management device 10B has not been deleted from management device 10B, so there are two beds, BED008 and BED012, currently linked to channel 4012. Therefore, the currently registered management device information related to transmitter 40J is information including all management devices 10 (i.e., management device A and management device 10B) in which the channel of transmitter 40J is currently registered.

[0051] When the control unit 22 generates the currently registered management device information, it generates similarity / difference information for each position of each ward based on the initial channel information, the current channel information, and the identification information (position information) (STEP 06). The similarity / difference information generated in this embodiment is information indicating similarity / difference between the management device 10 in which the channel of the transmitter 40 is currently registered and the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. In this embodiment, the channel associated with BED008 in the A ward at the current time is different from the channel associated with BED008 in the A ward at the time of initial setting. Therefore, the control unit 22 determines that the channel (4012) of the transmitter 40J registered at the current time is different from the channel (4008) of the transmitter 40H registered at the time of initial setting for BED008. On the other hand, for the beds other than BED008, it determines that the channel of the transmitter 40 registered at the current time is the same as the channel of the transmitter 40 registered at the time of initial setting. The control unit 22 generates difference / same information based on these determinations.

[0052] Based on the registered management device information and the time point identification information, the control unit 22 generates the most recent registration information indicating the management device 10 in which the channel of the transmitter 40 was registered at the time point closest to the current time point among the times when the channel of the transmitter 40 was registered in the management device 10 (STEP 07). In this embodiment, as of June 2022, only the transmitter 40J was lent and borrowed between the A ward and the B ward, and no other lending and borrowing of the transmitter 40 between the wards has occurred. Based on the difference / sameness information, the control unit 22 recognizes that the transmitter 40J was lent and borrowed between the A ward and the B ward, and that no other lending and borrowing of the transmitter 40 between the wards has occurred. For this reason, the control unit 22 determines that the management device 10 in which the channel of the transmitter 40 other than the transmitter 40J is registered at each time point is the same as the management device 10 in which the channel was registered at the time of initial setting. On the other hand, the channel of the transmitter 40J is registered in the management device 10A and the management device 10B as of June 2022. Therefore, the control unit 22 determines that there is a time (June 2022) when the channel of the transmitter 40J is registered in a management device 10A different from the management device 10B in which the channel of the transmitter 40J was registered at the time of initial setting. Then, the control unit 22 identifies the management device 10A in which the channel of the transmitter 40J is registered as of June 2022, and generates the most recently registered information. Note that, by using such most recently registered information, the user can recognize the ward in which the transmitter 40J is currently located (Ward A in this embodiment).

[0053] The control unit 22 generates display data based on the difference / same information, the identification information, the currently registered management device information, and the most recently registered information (STEP 08). In this embodiment, the control unit 22 generates display data indicating that the management device 10 in which the channel of the transmitter 40J is currently registered is different from the management device 10 in which the channel of the transmitter 40J was registered at the time of initial setting. More specifically, the control unit 22 generates display data for prompting the user to confirm the channel 4012 assigned to the transmitter 40J. Note that, for all transmitters 40, if the management device 10 in which the channel of the transmitter 40 is currently registered is the same as the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting, the control unit 22 generates display data for indicating this to the user. An example of such display data is display data including a message such as "Currently, there is no transmitter channel registered in a management device different from the management device registered at the time of initial setting."

[0054] The control unit 22 transmits the generated display data to the user terminal device 30 (STEP 09). When the user terminal device 30 receives the display data, an image 100 (see FIG. 6) based on the received display data is displayed on the display unit 33 of the user terminal device 30 (STEP 10).

[0055] Here, with reference to FIG. 6, an image 100 displayed on the display unit 33 will be described. As illustrated in FIG. 6, the image 100 includes various information related to the channel (4012) of the transmitter 40J. More specifically, the image 100 includes a message saying "Currently, there is a transmitter registered in a management device different from the management device registered at the time of initial setting.", the management device 10A and the management device 10B in which the channel of the transmitter 40J is registered, the channel of the transmitter 40J, the BED ID (BED008 and BED012) linked to the channel, and a symbol S1 indicating that the management device 10 in which the channel of the transmitter 40J was registered at the time closest to the current time among the times when the channel of the transmitter 40J was registered in the management device 10 is the management device 10A. Note that the above message is displayed based on the difference / sameness information. The management device 10A and the management device 10B in which the channel of the transmitter 40J is registered are displayed based on the currently registered management device information. The BED ID associated with the channel of the transmitter 40J is an indication based on the identification information. The symbol S1 is an indication based on the most recently registered information. By visually checking the image 100, the user can understand that the transmitter 40J is registered in a management device 10A different from the management device 10B in which the transmitter 40J was registered at the time of the initial setting, that the bed in which the transmitter 40J is used, and that the transmitter 40J is currently located in the ward A in which the management device 10A is installed.

[0056] According to the information processing device 20 having the above configuration, for each of the channels of the multiple transmitters 40 registered in the multiple management devices 10, difference / same information is generated based on the initial channel information and the subsequent channel information. By using the difference / same information, the user can easily know the channel of the transmitter 40 currently registered in a management device 10 different from the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. Therefore, according to the information processing device 20, the user can easily know whether the channel of the transmitter 40 is registered in a management device 10 other than the management device 10 in which the channel of the transmitter 40 was initially registered. Moreover, the information processing method, computer program, and non-transitory computer-readable medium having the above configuration can also achieve the same effect.

[0057] Furthermore, the information processing device 20 having the above configuration generates registration management device information including all management devices 10 in which at least the channel of the transmitter 40 is currently registered. Therefore, for example, if the channel of a certain transmitter 40 is registered in multiple management devices 10, the user can easily know that the channel is registered in duplicate by using such registration management device information.

[0058] Furthermore, according to the information processing device 20 having the above configuration, most recent registration information is generated based on the registration management device information and the time identification information, which indicates the management device 10 in which the channel of the transmitter 40 was registered at the time point that is closest to the current time point among the times when the channel of the transmitter 40 was registered in the management device 10. By using such most recent registration information, the user can know the management device 10 in which the channel of the transmitter 40 was registered at the time point that is closest to the current time point among the times when the channel of the transmitter 40 was registered in the management device 10. As a result, for example, in a case where one management device 10 is installed in each ward, the user can easily and quickly know the ward in which the transmitter 40 is currently located by using the most recent registration information.

[0059] Moreover, according to the information processing device 20 having the above configuration, difference / similarities information is generated for each location of each ward based on the initial channel information, the subsequent channel information, and the identification information (location information). Therefore, for each location of each ward, the user can at least grasp the differences / similarities between the management device 10 in which the channel of the transmitter 40 is registered at the current time and the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting. In other words, the user can grasp in more detail the differences / similarities between the management device 10 in which the channel of the transmitter 40 is registered at the current time and the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting.

[0060] (Second embodiment) Next, an information processing method executed by the information processing device 20 in the second embodiment will be described with reference to Figs. 2, 7 and 8. Note that in the second embodiment, the same parts as those in the first embodiment will be described using the same reference numerals as those in the first embodiment, and descriptions of overlapping parts will be omitted as appropriate. The second embodiment differs from the first embodiment in that a current channel search is executed. That is, the second embodiment differs from the first embodiment in that the control unit 22 acquires channel identification information. Note that the initial channel information and the post-channel information in this embodiment are the same as the initial channel information and the post-channel information in the first embodiment. Fig. 7 is a flow chart of the information processing method executed by the information processing device 20 in the second embodiment. Fig. 8 is a diagram showing an example of an image 200 based on display data.

[0061] STEP101 and STEP102 are similar to STEP01 and STEP02 in the first embodiment.

[0062] At this time, the user selects "current channel search" from among the four search execution buttons (see FIG. 2) displayed on the display unit 33 of the user terminal device 30. At this time, the user inputs the channel of the transmitter 40 that is the current target of the channel search. In this embodiment, as shown by the dashed line in FIG. 2, it is assumed that the user inputs 4012, which is the channel of the transmitter 40J. When the channel of the transmitter 40 that is the current target of the channel search is input and the current channel search is selected, the user terminal device 30 generates a request signal based on the selection and transmits the generated request signal to the information processing device 20. As a result, the information processing device 20 starts a current channel search (STEP 103). The user terminal device 30 generates channel identification information for identifying the channel based on the channel of the transmitter 40J that the user input to the user terminal device 30, and transmits the generated channel identification information to the information processing device 20 together with the request signal.

[0063] 7, a description will be given of STEP 104. The control unit 22 receives the channel identification information from the user terminal device 30, thereby acquiring the channel identification information (STEP 104).

[0064] The control unit 22 of the information processing device 20 generates an instruction signal for acquiring initial channel information and subsequent channel information from each of the management devices 10A to 10C based on the request signal received from the user terminal device 30. The control unit 22 transmits the instruction signal to each of the management devices 10A to 10C, thereby acquiring the current initial channel information and current channel information from each of the management devices 10A to 10C (STEP 105).

[0065] The control unit 22 generates currently registered management device information related to the channel of the transmitter 40J identified by the channel identification information based on the current channel information included in the post-channel information and the channel identification information (STEP 106). Note that the currently registered management device information generated in this embodiment is information including all management devices 10 (i.e., management device 10A and management device 10B) in which the channel of the transmitter 40J is currently registered.

[0066] After generating the currently registered management device information, the control unit 22 generates similarity / difference information related to the channel of the transmitter 40J identified by the channel identification information, based on the initial channel information and the current channel information (STEP 107). The management device 10A in which the channel of the transmitter 40J is currently registered is different from the management device 10B in which the channel of the transmitter 40J was registered at the time of initial setting. Therefore, the control unit 22 generates similarity / difference information indicating that the management device 10A in which the channel of the transmitter 40J is currently registered is different from the management device 10B in which the channel of the transmitter 40J was registered at the time of initial setting.

[0067] STEP 108 to STEP 111 are the same as STEP 07 to STEP 10 in the first embodiment. However, in STEP 108, the control unit 22 generates only the most recently registered information related to the channel of the transmitter 40J. That is, the most recently registered information generated by the control unit 22 in this embodiment is information indicating the management device 10A in which the channel of the transmitter 40J was registered as of June 2022, which is the closest time to the present time among the time when the channel of the transmitter 40J was registered in the management device 10A and the time when the channel was registered in the management device 10B. In addition, in STEP 109, the control unit 22 generates display data based on the difference / sameness information, the currently registered management device information, and the most recently registered information. Therefore, in STEP 111, an image 200 (see FIG. 8) different from the image 100 (see FIG. 6) in the first embodiment is displayed on the display unit 33 of the user terminal device 30.

[0068] Here, with reference to FIG. 8, an image 200 displayed on the display unit 33 will be described. As illustrated in FIG. 8, the image 200 includes information indicating a result of a current channel search for the channel (4012) of the transmitter 40J. More specifically, the image 200 includes a first message saying "The transmitter associated with the input channel is currently registered in a management device different from the management device registered at the time of initial setting", a second message indicating that the transmitter 40J is currently registered in the management device 10A and the management device 10B, and a symbol S2 indicating that the management device 10 in which the channel of the transmitter 40J was registered at the time closest to the current time among the times when the channel of the transmitter 40J was registered in the management device 10 is the management device 10A. The first message is a display based on the difference / sameness information. The second message is a display based on the currently registered management device information. The symbol S2 is a display based on the most recently registered information. By visually checking image 200, the user can understand that transmitter 40J is registered to a management device 10A different from the management device 10B with which it was registered at the time of initial configuration, and that transmitter 40J is currently located in ward A where management device 10A is installed.

[0069] In this embodiment, the information processing device 20 achieves the same effects as in the first embodiment.

[0070] Furthermore, according to the information processing device 20 having the above configuration, difference / same information is generated regarding the channel of the transmitter 40J identified by the channel identification information. Therefore, by using the difference / same information, a user can focus on the channel of a specific transmitter 40J and easily determine whether the channel of the transmitter 40J is registered in a management device 10A or a management device 10C other than the management device 10B to which the channel of the transmitter 40J was originally registered.

[0071] (Third embodiment) Next, an information processing method executed by the information processing device 20 in the third embodiment will be described with reference to Figs. 2, 9 and 10. Fig. 9 is a flowchart of the information processing method executed by the information processing device 20 in the third embodiment. Fig. 10 is a diagram showing an example of an image 300 based on display data. Note that in the third embodiment, the same parts as in the first embodiment will be described using the same reference numerals as in the first embodiment, and descriptions of overlapping parts will be omitted as appropriate. The third embodiment differs from the first embodiment in that an entire past channel search is performed.

[0072] The initial channel information in this embodiment is the same as the initial channel information in the first embodiment. However, in this embodiment, it is assumed that some transmitters 40 broke down between January 2022 and December 2022, and the following lending and borrowing (1) to (4) were performed. (1) The loan of transmitter 40J, which was originally used in BED012 in Ward B, to BED008 in Ward A as of June 2022. (2) The loan of transmitter 40P, originally used in BED022 in Ward C, to BED002 in Ward A as of October 2022. (3) The loan of transmitter 40Q, originally used in BED023 in Ward C, to BED003 in Ward A as of October 2022. (4) The loan of transmitter 40J, originally used in BED012 in Ward B, to BED028 in Ward C as of October 2022. In addition, since transmitter 40B that was initially used in BED002 was restored in November 2022, transmitter 40B is used in BED002 after November 2022, and transmitter 40P is returned to Ward C. In this embodiment, it is assumed that there has been no lending or borrowing of transmitter 40 other than the above (1) to (4).

[0073] Thus, the post-channel information in this embodiment includes not only the intermediate channel information exemplified in FIG. 5 (i.e., the intermediate channel information indicating the lending and borrowing of (1) above), but also the intermediate channel information indicating the lending and borrowing of (2) to (4) above. Each of the intermediate channel information indicating the lending and borrowing of (1) to (4) above includes time-specific information. For example, the intermediate channel information indicating the lending and borrowing of (2) above includes time-specific information indicating that the intermediate channel information is post-channel information as of October 2022. The current channel information includes time-specific information indicating that the current channel information is post-channel information as of the current time.

[0074] In this embodiment, the control unit 22 of the information processing device 20 acquires the post-channel information at each time point from January 2022 to December 2022 from each of the management devices 10A to 10C. Therefore, in this embodiment, the number of intermediate time points (i.e., the number from January 2022 to November 2022) is 11. That is, the control unit 22 acquires the current channel information and the intermediate channel information at the 11 time points.

[0075] STEP 201 and STEP 202 are the same as STEP 01 and STEP 02 in the first embodiment. However, in STEP 202, intermediate channel information indicating the lending and borrowing of the above (1) to (3) is registered in the management device 10A, and intermediate channel information indicating the lending and borrowing of the above (4) is registered in the management device 10C.

[0076] At this point in time, the user selects an overall past channel search from among the four search execution buttons (see FIG. 2) displayed on the display unit 33 of the user terminal device 30. When the overall past channel search is selected, the user terminal device 30 generates a request signal based on the selection and transmits the generated request signal to the information processing device 20. As a result, the information processing device 20 starts an overall past channel search (STEP 203).

[0077] The control unit 22 of the information processing device 20 generates an instruction signal for acquiring the initial channel information, the subsequent channel information, and the identification information from each of the management devices 10A to 10C based on the request signal received from the user terminal device 30. The control unit 22 acquires the initial channel information, the subsequent channel information, and the identification information from each of the management devices 10A to 10C by transmitting the instruction signal to each of the management devices 10A to 10C (STEP 204).

[0078] The control unit 22 generates current registration management device information and intermediate registration management device information from January 2022 to November 2022 based on the subsequent channel information (STEP 205). The current registration management device information is generated based on the current channel information, and the intermediate registration management device information is generated based on the intermediate channel information. The current registration management device information and the intermediate registration management device information are generated in association with the time identification information. For example, the intermediate registration management device information as of October 2022 is generated based on the intermediate channel information as of October 2022. The intermediate registration management device information as of October 2022 is information including all management devices 10 in which the channels of the transmitter 40 are registered as of October 2022.

[0079] In this embodiment, since the lending and borrowing of (1) to (4) above occurs, from June 2022 to September 2022, the channel associated with BED008 in Ward A and BED012 in Ward B is 4012, which is the channel of transmitter 40J. As of October 2022, the channel associated with BED002 in Ward A and BED022 in Ward C is 4022, which is the channel of transmitter 40P. From October 2022 to the present, the channel associated with BED003 in Ward A and BED023 in Ward C is 4023, which is the channel of transmitter 40Q. From October 2022 to the present, the channel associated with BED008 in Ward A, BED012 in Ward B, and BED028 in Ward C is 4012, which is the channel of transmitter 40J. Therefore, the channel associated with BED008 in Ward A from June 2022 to the present (i.e., 4012) is different from the channel associated with BED008 in Ward A at the time of initial setup (i.e., 4008). The channel associated with BED002 in Ward A from October 2022 (i.e., 4022) is different from the channel associated with BED002 in Ward A at the time of initial setup (i.e., 4002). The channel associated with BED003 in Ward A from October 2022 to the present (i.e., 4023) is different from the channel associated with BED003 in Ward A at the time of initial setup (i.e., 4003). The channel associated with BED028 in Ward C from October 2022 to the present (i.e., 4012) is different from the channel associated with BED028 in Ward C at the time of initial configuration (i.e., 4028).

[0080] On the other hand, the channels associated with other beds (i.e., BED001, BED004 to BED007, BED011 to BED016, and BED021 to BED027) from January 2022 to the present are the same as the channels associated with those other beds at the time of initial setting. Also, the channel associated with BED002 from November 2022 to the present is the same as the channel associated with BED002 at the time of initial setting.

[0081] In this embodiment, when a transmitter 40 is lent or borrowed, the channel information of the lent transmitter 40 is not deleted from the management device 10 in which it is registered at the time of lending. Therefore, for example, as of October 2022, there are two beds, BED002 and BED022, linked to the channel 4022. Therefore, the intermediate registered management device information regarding the transmitter 40P as of October 2022 is information including all management devices 10 (i.e., management device A and management device 10C) in which the channel of the transmitter 40P is registered as of October 2022.

[0082] When the control unit 22 generates the current registration management device information and the intermediate registration management device information, the control unit 22 generates difference / same information at each time point for each position of each ward based on the initial channel information, the subsequent channel information, and the identification information (position information) (STEP 206). For example, the channel associated with BED008 of ward A as of June 2022 is different from the channel associated with BED008 of ward A at the time of initial setting. Therefore, for BED008, the control unit 22 determines that the channel (4012) of the transmitter 40J registered as of June 2022 is different from the channel (4008) of the transmitter 40H registered at the time of initial setting. On the other hand, for beds other than BED008, the control unit 22 determines that the channel of the transmitter 40 registered as of June 2022 is the same as the channel of the transmitter 40 registered at the time of initial setting. The control unit 22 makes the above determination for each bed at each time point. The control unit 22 generates difference / same information based on these determinations.

[0083] STEP 207 and STEP 209 are the same as STEP 08 and STEP 10 of the first embodiment. However, in STEP 207, the control unit 22 generates display data based on the difference / same information, the identification information, and the registration management device information including the current registration management device information and the intermediate registration management device information. In STEP 210, the display unit 33 of the user terminal device 30 displays an image 300 as shown in FIG. 10.

[0084] Here, with reference to FIG. 10, an image 300 displayed on the display unit 33 will be described. As illustrated in FIG. 8, the image 300 includes a BED ID associated with the channel of the transmitter 40, the channel of the transmitter 40 at the time of initial setting, and the difference / sameness information at each time point from January 2022 to December 2022. In this embodiment, if the management device 10 in which the channel of a certain transmitter 40 is registered at a certain time point is the same as the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting, the character "OK" is displayed as the difference / sameness information. On the other hand, if the management device 10 in which the channel of a certain transmitter 40 is registered at a certain time point is different from the management device 10 in which the channel of the transmitter 40 was registered at the time of initial setting, the channel of the transmitter 40 registered at that time point is displayed as the difference / sameness information. For example, the management device 10A in which the channel (4001) of the transmitter 40A linked to BED001 is registered as of October 2022 is the same as the management device 10A in which the channel of the transmitter 40A was registered at the time of initial setting. For this reason, the word "OK" is displayed in the square 300A. On the other hand, the management device 10A in which the channel (4022) of the transmitter 40P linked to BED002 is registered as of October 2022 is different from the management device 10C in which the channel of the transmitter 40P was registered at the time of initial setting. For this reason, the number "4022" representing the channel of the transmitter P is displayed in the square 300B.

[0085] By visually checking image 300, the user can chronologically know whether or not the channel of transmitter 40 has been registered in a management device 10 other than the management device 10 in which it was initially registered between January 2022 and the present time. In addition, by visually checking image 300, the user can also know which management device 10 the transmitter 40 was registered in at the time when the channel of transmitter 40 was registered in a management device 10 other than the management device 10 in which it was initially registered.

[0086] In this embodiment, the information processing device 20 achieves the same effects as in the first embodiment.

[0087] Moreover, according to the information processing device 20 having the above configuration, the registration management device information is generated in association with time point identification information indicating the time point at which the post-channel information is generated. Therefore, the user can, for example, grasp the management devices 10 to which the transmitter 40 has been registered in chronological order.

[0088] Moreover, according to the information processing device 20 having the above configuration, the difference / same information is generated based on the registration management device information generated in association with the time point identification information indicating the time point at which the subsequent channel information is generated. Therefore, for example, the user can grasp in chronological order whether the channels of the multiple transmitters 40 have not been registered in a management device 10 other than the management device 10 to which the channels were initially registered.

[0089] Furthermore, according to the information processing device 20 having the above configuration, the subsequent channel information includes intermediate channel information at a plurality of intermediate points in time that are different from each other. Therefore, even if there are a plurality of intermediate points in time that are after the initial setting point in time and before the current point in time, the user can easily know whether the transmitter is registered in a management device 10 other than the management device 10 in which the transmitter was originally registered.

[0090] (Fourth embodiment) Next, an information processing method executed by the information processing device 20 in the fourth embodiment will be described with reference to Figs. 2, 11, and 12. Fig. 11 is a flow chart of the information processing method executed by the information processing device 20 in the fourth embodiment. Fig. 12 is a diagram showing an example of an image 400 based on display data. In the fourth embodiment, the same parts as those in the first to third embodiments will be described using the same reference numerals as those in the first to third embodiments, and descriptions of overlapping parts will be omitted as appropriate. The fourth embodiment differs from the first to third embodiments in that a past channel search is performed. In addition, the initial channel information in this embodiment is the same as the initial channel information in the first embodiment, and the post-event channel information in this embodiment is the same as the post-event channel information in the third embodiment.

[0091] STEP 301 and STEP 302 are similar to STEP 201 and STEP 202 in the third embodiment.

[0092] At this time, the user selects past channel search from among the four search execution buttons (see FIG. 2) displayed on the display unit 33 of the user terminal device 30. At this time, the user inputs the channel of the transmitter 40 to be the target of the past channel search. In this embodiment, as shown by the dashed line in FIG. 2, it is assumed that the user inputs 4012, which is the channel of the transmitter 40J. When the channel of the transmitter 40 to be the target of the past channel search is input and past channel search is selected, the user terminal device 30 generates a request signal based on the selection and transmits the generated request signal to the information processing device 20. As a result, the information processing device 20 starts the past channel search (STEP 303). The user terminal device 30 generates channel identification information for identifying the channel based on the channel of the transmitter 40J input by the user to the user terminal device 30, and transmits the generated channel identification information to the information processing device 20 together with the request signal.

[0093] Returning to Fig. 11, a description will be given of STEP 304. STEP 304 is similar to STEP 104 in the second embodiment.

[0094] The control unit 22 of the information processing device 20 generates an instruction signal for acquiring the initial channel information and the subsequent channel information from each of the management devices 10A to 10C based on the request signal received from the user terminal device 30. The control unit 22 acquires the initial channel information and the subsequent channel information from each of the management devices 10A to 10C by transmitting the instruction signal to each of the management devices 10A to 10C (STEP 305).

[0095] The control unit 22 generates current registration management device information and intermediate registration management device information related to the channel of the transmitter 40J identified by the channel identification information based on the subsequent channel information and the channel identification information (STEP 306). Note that, even in this embodiment, when the transmitter 40 is lent or borrowed, the channel information of the lent transmitter 40 is not erased from the management device 10 registered at the time of lending. Therefore, as of June 2022, there are two beds, BED008 and BED012, linked to the channel of 4012. Also, as of October 2022, there are three beds, BED008, BED012, and BED028, linked to the channel of 4012. Therefore, the intermediate registration management device information related to the transmitter 40J as of June 2022 is information including all management devices 10 (i.e., management device A and management device 10B) in which the channel of the transmitter 40J is registered as of June 2022. In addition, the intermediate registration management device information regarding transmitter 40J as of October 2022 is information that includes all management devices 10 (i.e., management device A, management device 10B, and management device 10C) in which the channel of transmitter 40J is registered as of October 2022.

[0096] When the control unit 22 generates the current registration management device information and the intermediate registration management device information, it generates difference / same information related to the channel of the transmitter 40J identified by the channel identification information for each time point based on the initial channel information and the subsequent channel information (STEP 307). The channel associated with BED008 of Ward A from June 2022 to the present time is different from the channel associated with BED008 of Ward A at the time of initial setting. Therefore, the control unit 22 determines that for BED008, the channel (4012) of the transmitter 40J registered from June 2022 to the present time is different from the channel (4008) of the transmitter 40H registered at the time of initial setting. In addition, the channel associated with BED028 of Ward C from October 2022 to the present time is different from the channel associated with BED028 of Ward C at the time of initial setting. Therefore, the control unit 22 determines that, for BED028, the channel (4012) of the transmitter 40J registered from October 2022 to the present time is different from the channel (4028) of the transmitter 40V registered at the time of the initial setting. The control unit 22 generates difference / same information based on these determinations.

[0097] The control unit 22 generates the most recent registration information indicating the management device 10 in which the channel of the transmitter 40J was registered at the time closest to the current time among the times when the channel of the transmitter 40J was registered in the management device 10 based on the registration management device information and the time identification information (STEP 308). In this embodiment, the transmitter 40J is loaned from Ward B to Ward A from June 2022 to September 2022, and is loaned from Ward A to Ward C from October 2022 to the current time. For this reason, the control unit 22 determines that there are times (June 2022 and October 2022) when the channel was registered in the management device 10A and management device 10C different from the management device 10B in which the channel of the transmitter 40J was registered at the time of initial setting. Then, the control unit 22 identifies the management device 10C in which the channel of the transmitter 40J was registered at the time closest to the current time among these times (October 2022 in this embodiment), and generates the most recent registration information. By using such recently registered information, the user can recognize the ward in which the transmitter 40J is currently located (ward C in this embodiment).

[0098] STEP 309 to STEP 311 are the same as STEP 207 to STEP 209 in the third embodiment. However, in STEP 309, the control unit 22 generates display data based on the difference / same information, the registration management device information including the current registration management device information and the intermediate registration management device information, and the most recently registered information. In addition, in STEP 310, an image 400 as shown in FIG. 12 is displayed on the display unit 33 of the user terminal device 30.

[0099] Here, an image 400 displayed on the display unit 33 will be described with reference to FIG. 12. As illustrated in FIG. 12, the image 400 includes information indicating a result of a past channel search for the channel (4012) of the transmitter 40J. More specifically, the image 400 includes a third message indicating that "the transmitter associated with the input channel is registered in a management device different from the management device in which the transmitter 40J was registered at the time of initial setting", a fourth message indicating that the transmitter 40J was registered in the management device 10B at the time of initial setting and then registered in the management device 10A and the management device 10C in that order, and a symbol S3 indicating that the management device 10 in which the channel of the transmitter 40J was registered at the time closest to the current time among the times when the channel of the transmitter 40J was registered in the management device 10 is the management device 10C. The fourth message includes three messages, "Registered in the management device 10A", "Registered in the management device 10B", and "Registered in the management device 10C", and the three messages are displayed in chronological order. Transmitter 40J is loaned from ward B to ward A, and then loaned to ward C. In other words, the channel of transmitter 40J is registered in management device 10B at the time of initial configuration, then registered in management device 10A as of June 2022, and further registered in management device 10C in October of the same year. For this reason, the three messages "Registered in management device 10B," "Registered in management device 10A," and "Registered in management device 10C" are displayed on display unit 33 in this order from the bottom up:

[0100] The third message is a display based on the difference / sameness information. The fourth message is a display based on the registered management device information. Symbol S3 is a display based on the most recently registered information. By visually checking the image 400, the user can understand that the transmitter 40J was registered in the management device 10B during initial setup, and was then registered in the management device 10A and management device 10C in that order, and that the transmitter 40J is currently located in Ward C.

[0101] In this embodiment, the information processing device 20 achieves the same effects as in the first and second embodiments.

[0102] Furthermore, according to the information processing device 20 having the above configuration, the registration management device information generated based on the subsequent channel information includes intermediate registration management device information and current registration management device information. The intermediate registration management device information is information including all management devices 10 in which the channel of the transmitter 40 was registered at an intermediate point in time that was after the initial setting point in time and before the current point in time. Therefore, by using such registration management device information, the user can know the management devices 10 in which the transmitter 40 was registered so far.

[0103] The above-described embodiments are provided for the purpose of facilitating understanding of the present disclosure, and are not intended to limit the present disclosure. The present disclosure may be modified or improved without departing from the spirit and scope of the present disclosure.

[0104] In the above embodiment, one transmitter 40 is used for each bed installed in each ward, but multiple transmitters 40 may be used for one bed, and there may be beds for which no transmitter 40 is used.

[0105] In the above embodiment, the post-channel information includes the time point specific information, but it does not have to include the time point specific information.

[0106] In the above embodiment, one management device 10 is installed in each of the wards (Ward A, Ward B, and Ward C) included in X Hospital, but multiple management devices 10 may be installed in at least one of these wards.

[0107] In the first and third embodiments, the control unit 22 does not need to acquire the identification information. In this case, the control unit 22 generates the difference / same information based on the initial channel information and the post-channel information.

[0108] In the second and fourth embodiments, the user inputs the channel (4012) of one transmitter 40 as the channel of the transmitter 40 to be searched for the current channel or past channel, but the user may input the channels of multiple transmitters 40.

[0109] In the second embodiment, the control unit 22 may generate, based on the registration management device information and the time identification information, recent registration information indicating the management device 10 in which the channel of the transmitter 40 was registered at the time point that is closest to the current time point among the times when the channel was registered in the management device 10. When the control unit 22 generates the recent registration information, the control unit 22 generates display data based on the difference / sameness information, the identification information, the registration management device information including the current registration management device information and the intermediate registration management device information, and the recent registration information.
