DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. For the sake of convenience, descriptions of components having the same reference numerals as those already described in the description of the embodiments will be omitted. Furthermore, for the sake of convenience, the dimensions of each component shown in the drawings may differ from the actual dimensions of each component. <Configuration of medical system 100>

[0011] Fig. 1 is a configuration diagram of a medical system 100 including an alarm information processing device 1 according to an embodiment of the present disclosure. As shown in Fig. 1, the medical system 100 includes a plurality of terminal devices 2 attached to each patient P, a central monitor device 3 connected to the plurality of terminal devices 2 via an in-hospital network 20 using a plurality of antennas 2A, and the alarm information processing device 1.

[0012] The terminal device 2 is, for example, a telemeter or a vital sign monitoring device, and is installed in the patient P's hospital room or carried by the patient P. The terminal device 2 acquires signals containing the patient P's vital sign and transmits the acquired signals to the central monitoring device 3 via the hospital network 20. The central monitoring device 3 is installed in a nurse's station or other location where medical staff are stationed, and aggregates signals containing the patient P's vital sign transmitted from multiple terminal devices 2. The central monitoring device 3 displays the aggregated signals on a monitor or outputs them externally. Medical staff stationed at the nurse's station monitor the signals displayed on the monitor of the central monitoring device 3 and check the patient P's vital sign. The central monitoring device 3 can determine whether a signal loss has occurred, for example, based on whether the signal strength of the signal from each terminal device 2 is above a threshold. The central monitoring device 3 can also display a warning depending on the state of the signal loss. The central monitoring device 3 can also analyze the signals from each terminal device 2 and output the results as log information.

[0013] However, among the radio wave blackouts of the radio waves transmitted by the terminal device 2, it is difficult for medical staff to visually recognize short-term radio wave blackouts that last for a predetermined time (for example, 5 seconds) or less.

[0014] For this reason, the medical system 100 includes an alarm information processing device 1 in addition to the central monitoring device 3. By connecting the central monitoring device 3 to a communication line such as a wireless LAN, or by using a storage medium such as a USB memory, the alarm information processing device 1 acquires the log information analyzed and output by the central monitoring device 3. Furthermore, the alarm information processing device 1 determines the radio wave interruption state of the radio waves transmitted by the terminal device 2 from the log information, and outputs alarm information etc. as necessary. <Configuration of alarm information processing device 1>

[0015] FIG. 2 is a block diagram showing the configuration of an alarm information processing device 1 according to an embodiment of the present disclosure. The alarm information processing device 1 includes an input unit 10, a control unit 11, a calculation unit 12, a storage unit 13, an output unit 14, a UI operation unit 15, and a display unit 16. The input unit 10 receives input of log information analyzed by the central monitor device 3. The control unit 11 reads and executes programs stored in the storage unit 13 to control various operations of the alarm information processing device 1. The calculation unit 12 calculates, from the log information, the frequency of signal interruptions in radio waves transmitted by the terminal device 2, and generates alarm information. The storage unit 13 stores the programs executed by the control unit 11 and the alarm information generated by the calculation unit 12. The output unit 14 displays the alarm information stored in the storage unit 13 as an alarm report on a monitor (display unit 16) or prints it on a printer. The UI operation unit 15 receives, from an operator (user), a designation of the output format of the alarm report and the terminal device 2 to be measured. <Alarm report output format>

[0016] In order to explain the output form of the alarm report output by the alarm information processing device 1 according to the embodiment of the present disclosure, the output form of the alarm report output by a conventional alarm information processing device 1 is shown in FIG. 3 for comparison.

[0017] 3, the alarm report output by the alarm information processing device 1 displays, for multiple terminal devices 2, the ID of each terminal device 2, the number of days that each terminal device 2 was used by patient P, the average number of times signal loss occurred per day for each terminal device 2, and the average number of times signal loss occurred per day in each time period for each terminal device 2. In one example of the alarm report shown in Fig. 3, a summary report for one month is displayed for three terminal devices 2 with IDs 001 to 003. In addition, for the time periods in which signal loss occurred, the display mode, such as the background color, is changed depending on the number of times signal loss occurred.

[0018] Generally, when short-term signal loss occurs frequently, it tends to be caused by equipment defects such as a malfunction of the terminal device 2 itself or a broken connection cable of the terminal device 2. Furthermore, when long-term signal loss occurs that lasts for a predetermined time (for example, 10 seconds) or longer, it tends to be caused by a faulty antenna or improper attachment of the terminal device, such as temporary deterioration of the contact state when the patient moves during measurement. However, the alarm report output format of the conventional alarm information processing device 1 does not display information regarding the duration of each signal loss. Therefore, with the conventional alarm information processing device 1, it may be difficult for the operator to notice that the signal loss displayed in the alarm report is a short-term signal loss. Furthermore, it may be difficult for the operator to determine from the alarm report whether the cause of the signal loss is due to a faulty antenna or improper attachment, such as temporary deterioration of contact when the patient P moves during measurement, or a device malfunction, such as a malfunction of the terminal device 2 itself or a broken connection cable of the terminal device 2.

[0019] The alarm information processing device 1 according to this embodiment has improved such inconvenience. Fig. 4 is a diagram showing a first output form of an alarm report output by the alarm information processing device 1 according to an embodiment of the present disclosure. The example of the alarm report shown in Fig. 4 displays a one-day summary report for three terminal devices 2 with IDs 001 to 003. The example of the alarm report shown in Fig. 4 also displays the number of signal outages that occurred per unit time in each time period, the longest duration, and the cumulative time in a list format.

[0020] In a first output form (FIG. 4) of the alarm report output by the alarm information processing device 1 of this embodiment, information on the occurrence of signal blackouts per unit time, the duration of each signal blackout (for example, the longest duration (seconds)), and transition information showing the occurrence of signal blackouts per unit time are displayed. Therefore, the worker can recognize from the alarm report that a short-term signal blackout has occurred due to a malfunction of the terminal device 2 itself or a device defect such as a broken cable connecting the terminal device 2. This allows the worker to investigate the detailed cause of the signal blackout. Specifically, this alarm report not only shows the frequency of signal blackouts at each terminal (for example, the number of times signal blackouts occurred per unit time), but also the average number of seconds for each signal blackout and the longest duration (seconds) of signal blackouts per unit time. In other words, in addition to the frequency of signal blackouts, it is possible to grasp at a glance whether signal blackouts are occurring for a relatively long period of time.

[0021] Fig. 5 is a diagram showing a second output form of an alarm report output by the alarm information processing device 1 according to an embodiment of the present disclosure. The example of the alarm report shown in Fig. 5 displays a one-day summary report for three terminal devices 2 with IDs 001 to 003. The example of the alarm report shown in Fig. 5 also displays, in a list-like format, the number of times signal outages occurred per unit time for each duration of the signal outage in each time period.

[0022] In the second output form (FIG. 5) of the alarm report output by the alarm information processing device 1 of this embodiment, the occurrence status of signal blackouts per unit time, information on the duration of each signal blackout, and transition information showing the occurrence status of signal blackouts per unit time are displayed in detail. Therefore, workers can easily understand the occurrence of short-term signal loss from the alarm report. Therefore, workers can easily investigate the detailed cause of the signal loss. Specifically, this alarm report displays the distribution of the duration of signal loss for each terminal in each time period. This makes it easy to understand the time periods when signal loss is likely to occur, whether or not each terminal has many short-term signal loss episodes, which terminals have the most signal loss, etc. <Waveform data output format>

[0023] Fig. 6 is a diagram showing a first output form of waveform data output by the alarm information processing device 1 according to an embodiment of the present disclosure. The example of the alarm report shown in Fig. 6 displays, as waveform data, the time transition of the frequency of occurrence of short-term signal loss from a one-month summary report for two terminal devices 2 (IDs 001 and 003). In each waveform data, the horizontal axis shows the number of days of measurement from the start date of the alarm report summary, and the vertical axis shows the number of times of short-term signal loss.

[0024] In the waveform data (shown at the top of FIG. 6) of terminal device 2 (ID is 001), the number of short-term radio wave interruptions is low, and there is little possibility of a malfunction of the terminal device 2 itself or a disconnection of the connection cable of terminal device 2. Therefore, it can be seen that the radio wave transmission status of terminal device 2 (ID is 001) is stable. Waveform data with such stable radio wave transmission status may be set as reference data.

[0025] On the other hand, the waveform data (shown at the bottom of Fig. 6) of terminal device 2 (ID is 003) shows that there are many short-term radio wave interruptions over a long period of time, which suggests that there is a high possibility of a device malfunction such as a breakdown in the terminal device 2 itself or a disconnection in the connection cable of terminal device 2. Therefore, the worker can easily grasp the status of the device malfunction related to terminal device 2 (ID is 003).

[0026] The two terminal devices 2 (IDs 001 and 003) may be selected by the ID of the terminal device 2 specified by the operator on the UI operation unit 15, or may be automatically selected by the alarm information processing device 1 based on the radio wave interruption occurrence status of each of the multiple terminal devices 2. The number of selected terminal devices 2 is not limited to two, and may be three or more. Furthermore, in the example shown in Fig. 6, multiple waveform data are displayed side by side, but multiple waveform data may also be displayed together as a single graph (for example, superimposed).

[0027] 7 is a diagram showing a second output form of waveform data output by the alarm information processing device 1 according to an embodiment of the present disclosure. The example of the alarm report shown in FIG. 7 displays, as waveform data, the time transition of the frequency of occurrence of short-term signal loss from the aggregation report for the past month and the aggregation report for the most recent month for the terminal device 2 (ID is 003). In each waveform data, the horizontal axis shows the number of days of measurement from the start date of the alarm report aggregation, and the vertical axis shows the number of times of short-term signal loss.

[0028] In the waveform data (shown in the upper part of FIG. 7) formed from the aggregate report for the past month, the number of short-term radio wave interruptions is low, and there is little possibility of a malfunction of the terminal device 2 itself or a disconnection of the connection cable of the terminal device 2. Therefore, it can be seen that the radio wave transmission status of the terminal device 2 with ID 001 is stable. Waveform data with such stable radio wave transmission status may be set as the reference data.

[0029] On the other hand, the waveform data (shown at the bottom of Figure 7) formed from the most recent month's summary report shows that there have been many short-term signal outages over a long period of time, which suggests that there is a high possibility of equipment malfunction, such as a breakdown in the terminal device 2 itself or a break in the connection cable of the terminal device 2. By comparing the signal outage situations of the same terminal in this way, it is possible to easily grasp the worsening state of the equipment malfunction.

[0030] The start time of aggregation (April 1, 2020 and April 1, 2021 in the example of FIG. 7) and aggregation period (one month in the example of FIG. 7) of the aggregation report that serves as the source data for creating the waveform data may be a period specified by the operator on the UI operation unit 15, or may be automatically selected by the alarm information processing device 1 based on the occurrence status of signal outages in each of the multiple terminal devices 2. Furthermore, although the example shown in FIG. 7 displays multiple waveform data side by side, the multiple waveform data may also be displayed together as a single graph. <Failure prediction process flowchart>

[0031] FIG. 8 is a diagram showing a failure prediction processing flow of the alarm information processing device 1 according to an embodiment of the present disclosure. After the failure prediction process starts, the operator determines whether a short-term radio wave interruption has occurred (whether the frequency of short-term radio wave interruptions is high) based on signals containing the patient P's biological information transmitted from multiple terminal devices 2 (S100).

[0032] Next, if a short-term radio wave interruption occurs (Yes in S100), the worker identifies the terminal device 2 in which the short-term radio wave interruption occurred and the terminal device 2 in which the short-term radio wave interruption did not occur (S101, S102). At this time, the alarm information processing device 1 may automatically identify the terminal device 2 in which the short-term radio wave interruption occurred and the terminal device 2 in which the short-term radio wave interruption did not occur.

[0033] Next, alarm information for a predetermined period (for example, one month) is compiled (S103) based on signals including biological information of the patient P transmitted from the multiple terminal devices 2. Based on the compiled alarm information, the alarm information processing device 1 generates waveform data as shown in Fig. 6 for two or more terminal devices 2 selected by the operator from the multiple terminal devices 2 (S104).

[0034] Next, the worker estimates from the generated waveform data whether the terminal device 2 experiencing the short-term radio wave interruption has a malfunction in the device itself or whether a poor connection has occurred in the connection cable (S105). For this estimation, for example, electrocardiogram data (an example of a biological waveform based on biological information acquired by the terminal device 2) at the time of the radio wave interruption at each terminal is used.

[0035] At this time, the alarm information processing device 1 may automatically estimate, from the generated waveform data, whether the terminal device 2 experiencing a short-term signal interruption has a poor connection in the connection cable, a lead wire in the connection cable that is about to break, or a device malfunction. If the generated electrocardiogram data has an irregular shape that is significantly different from normal electrocardiogram data, it can be estimated that the connection cable has a poor connection or a lead wire in the connection cable is about to break. If the generated electrocardiogram data has a waveform (e.g., a triangular wave) that indicates a state in which transmission (acquisition) has not been possible, it can be estimated that the device is malfunctioning. In other words, by analyzing the shape of the electrocardiogram data (biological waveform based on biological information) from the terminal device experiencing a signal interruption, it can be estimated that the connection cable has a poor connection or a lead wire in the connection cable that is about to break, or that the device itself is malfunctioning.

[0036] Then, the failure prediction process ends.

[0037] Note that the processing in Fig. 8 is merely an example, and the processing can be modified as appropriate depending on the purpose. For example, if one wishes to grasp an overview of the frequency of signal loss in each terminal device and the duration of each signal loss, one can output the report shown in Fig. 4. If one wishes to grasp the duration of each signal loss in more detail than that shown in Fig. 4, one can output the report shown in Fig. 5. If there is a terminal device 2 suspected of having a malfunction, one can output a report comparing multiple terminals as shown in Fig. 6 to grasp the specific deterioration. If one wishes to grasp the degree of increase (degree of deterioration) in the frequency of signal loss in a certain terminal, one can output a report as shown in Fig. 7. Of course, if it is desired to grasp the overall state of radio wave interruptions within the hospital, an integrated report including the reports shown in FIGS. 4 to 7 may be output.

[0038] Furthermore, bio-waveforms (waveform information such as electrocardiogram data) based on the bio-information acquired by the terminal device 2 may be output together with the report information. For example, bio-waveforms during a time period when a short signal loss occurs may be output together with the report information shown in Figs. 4 to 7. By checking the shape of the bio-waveforms, the user can easily estimate whether the cause of the short signal loss is the cable or a malfunction of the device itself. The biological waveform is not limited to electrocardiogram data, but may be waveform data of other parameters such as blood pressure waveform data, etc. Furthermore, the biological waveform of the terminal explicitly selected by the user may be displayed together with the report information shown in Figures 4 to 7, regardless of whether or not a short-term signal interruption has occurred.

[0039] Although the embodiments of the present disclosure have been described above, it goes without saying that the technical scope of the present disclosure should not be interpreted as being limited by the description of the embodiments. The present embodiments are merely examples, and it will be understood by those skilled in the art that various modifications of the embodiments are possible within the scope of the invention described in the claims.
