[0036] When the control unit 201 receives the above-mentioned specific information from the transmitter 210, the control unit 201 may transmit the biological information and the alarm together with the specific information in association with the specific information to the central monitor 100. The specific information includes, for example, the patient's bed number, the patient's ID, the IP address of the transmitter 210, and the like.

[0037] The communication unit 203 is an interface for communicatively connecting the centralized receiver 200 with the central monitor 100 and the transmitter 210. The communication unit 203 may be configured with, for example, an input terminal, an antenna, a front-end circuit, and the like.

[0038] (Central Monitor 100) 5 is a block diagram of the hardware configuration of the central monitor 100. The central monitor 100 includes a control unit 101, a storage unit 102, a communication unit 103, and a display unit 104. These components are connected to each other via a bus. The basic configurations of these components are similar to the basic configurations of the corresponding components of the bedside monitor 110, so duplicated explanations will be omitted.

[0039] The control unit 101 receives biological information, vital alarms, and technical alarms from each bedside monitor 110 and each transmitter 210 via the communication unit 103.

[0040] The storage unit 102 stores the biological information, the vital alarm, and the technical alarm in association with the time of receipt. The biological information, the vital alarm, and the technical alarm may be stored in association with specific information.

[0041] The control unit 101 calculates the alarm occurrence time. The alarm occurrence time is the time during which at least one of the vital alarm and the technical alarm has occurred. Hereinafter, when the vital alarm and the technical alarm are not distinguished from each other, these alarms are also simply referred to as alarms. As described above, the same alarm may be continuously transmitted. In this case, the alarm occurrence time may be the time from when the alarm is received until the alarm is no longer received. The control unit 201 calculates the proportion of the alarm occurrence time. The proportion of the alarm occurrence time is the proportion of the alarm occurrence time to the predetermined time. The predetermined time may be, for example, a work shift, an hour, a day, a week, a month, a June, or a year.

[0042] The control unit 101 may calculate and output at least one of the alarm occurrence time and the ratio of the alarm occurrence time for each continuous time period. Note that output includes displaying on the display unit 104, transmitting to another device via the communication unit 103, and the like.

[0043] The control unit 201 can output at least one of the alarm occurrence time and the ratio of the alarm occurrence time in a manner that allows distinction for each type of alarm (vital alarm, technical alarm).

[0044] Based on the specific information, the control unit 201 can calculate the alarm occurrence time (total alarm occurrence time) or the proportion of alarm occurrence time for each group to which the subject of the biological information belongs, and output the calculated alarm occurrence time or the proportion of alarm occurrence time for the group specified by the user on an input unit (not shown) such as a touch panel of the central monitor 100.

[0045] Fig. 6 is a diagram showing the alarm occurrence time for each time period and the ratio of the alarm occurrence time, etc. Fig. 7 is a diagram showing a graph of the ratio of the alarm occurrence time for each time period.

[0046] In the example of FIG. 6, the results of the total monitoring time, total alarm occurrence time, alarm occurrence time ratio, and alarm non-occurrence time ratio for the 1-month aggregation period are shown for each time period. The average number of subjects to be monitored is 13. The subjects to be aggregated are patients in the same ward, which is a specified group. The total monitoring time is the sum of the time during which vital signs were monitored in each time period, and is calculated based on the time of entering and leaving each bed. The total alarm occurrence time is the sum of the alarm occurrence times during the total monitoring time. The ratio of the alarm occurrence time is the ratio of the total alarm occurrence time to the total monitoring time (total alarm occurrence time / total monitoring time x 100). The total alarm non-occurrence time is the sum of the time other than the alarm occurrence time during the total monitoring time. The ratio of the alarm non-occurrence time is the ratio of the total alarm occurrence time to the total monitoring time (total alarm occurrence time / total monitoring time x 100).

[0047] As described above, the predetermined group to be counted may be a group designated by a user. The subjects to be counted for the biological information may be patients or the like who are under the care of a care staff member who belongs to the same working time zone.

[0048] The collection period can be set arbitrarily, and may be a shift, an hour, a day, a week, six months, or a year. The monitoring target can be any, and may be one person.

[0051] In the example of Fig. 8, the percentage of time that a vital alarm occurred and the percentage of time that a technical alarm occurred are displayed in different lines so that they can be distinguished from each other. In other words, the percentage of time that an alarm occurred is displayed so that it can be distinguished by alarm type.

[0052] In the example of FIG. 9, the percentage of time when a vital alarm occurred and the percentage of time when a technical alarm occurred are displayed as bar graphs divided into different colors or patterns, making it possible to distinguish between them.

Fig. 12 is a diagram showing a pie chart of the ratio of the alarm occurrence time per day.

[0054] In the example of Fig. 10, the results of the aggregation for the aggregation period in January are shown for each day (date) including the total alarm occurrence time, the percentage of alarm occurrence time, and the percentage of non-alarm occurrence time. In the example of Fig. 11, the percentage of alarm occurrence time, etc. are shown by bar graphs for each day. In the example of Fig. 12, the percentage of alarm occurrence time, etc. are shown by pie charts for each day.

[0056] The control unit 101 may calculate the alarm occurrence time or the ratio of the alarm occurrence time for each predetermined attribute of the alarm, and output the alarm occurrence time in a manner that allows distinction for each attribute. The predetermined attributes include, for example, high priority, medium priority, and low priority, which are set according to urgency and importance. The predetermined attributes may be detailed parameters of a vital alarm or technical alarm, or a shift of a care staff member, etc. Detailed parameters of a vital alarm include, for example, a decrease in arterial oxygen saturation and a decrease in blood pressure. Detailed parameters of a technical alarm include, for example, "electrode check," "loss of radio wave," and "probe check."

Fig. 14 is a diagram showing a bar graph showing the ratio of alarm occurrence time for each time period in a manner that allows distinction for each predetermined attribute of the alarm.

[0058] In the example of Fig. 13, the proportion of alarm occurrence time for each successive time period is shown in a manner that allows distinction between high priority alarms, medium priority alarms, and low priority alarms. In the example of Fig. 14, the proportion of alarm occurrence time for each successive time period is shown as a bar graph in which the attributes of high priority, medium priority, and low priority are each divided into different colors or patterns, allowing distinction between these.

[0059] Fig. 15 is a diagram showing alarm occurrence times and alarm non-occurrence times for each time period, and Fig. 16 is a diagram showing bar graphs of alarm occurrence times and alarm non-occurrence times for each time period.

[0060] In the example of Fig. 15, the total alarm occurrence time (sum of alarm occurrence times) and the total non-alarm occurrence time (sum of alarm non-occurrence times) are tabulated for each time period in January. In the example of Fig. 16, the total alarm occurrence time and the total non-alarm occurrence time are tabulated for each time period in January as a bar graph.

[0062] 17 is a flowchart showing the operation of the central monitor 100. This flowchart can be executed by the control unit 101 of the central monitor 100 in accordance with a program.

[0063] The control unit 101 determines whether an alarm has been received (S101). If the control unit 101 determines that an alarm has not been received (S101: NO), it repeats step S101.

[0064] When the control unit 101 determines that an alarm has been received (S101: YES), it calculates (measures) the time during which the alarm was received, and calculates, for each type of alarm, the alarm occurrence time and the percentage of the alarm occurrence time for each time period (S102).

[0065] The control unit 101 outputs the alarm occurrence time and the ratio of the alarm occurrence time for each time period in a manner that allows the type of alarm to be distinguished (S103).

[0066] This embodiment provides the following advantages.

[0067] The system calculates and outputs the alarm occurrence time or the percentage of alarm occurrence time during which at least one of a vital alarm that notifies abnormalities in vital information and a technical alarm that notifies abnormalities in measuring equipment, etc. has occurred. This makes it possible to quantitatively grasp the workload of medical personnel caused by alarm occurrences during vital information measurement.

[0068] Furthermore, at least one of a vital alarm and a technical alarm is received, and an alarm occurrence time or a ratio of an alarm occurrence time is calculated based on at least one of the received vital alarm and technical alarm. This makes it possible to comprehensively grasp the workload of medical personnel caused by alarm occurrence.

[0069] Furthermore, the alarm occurrence time or the ratio of the alarm occurrence time is output in a manner that allows the type of alarm to be distinguished, thereby enabling a quantitative understanding of the workload of medical staff for each type of alarm.

[0070] Furthermore, the system calculates the alarm occurrence time or the ratio of alarm occurrence time for each consecutive time period, and outputs the alarm occurrence time or the ratio of alarm occurrence time for each time period. This allows the workload of medical staff to be quantitatively understood for each time period.

[0071] Furthermore, the system calculates the alarm occurrence time or the ratio of the alarm occurrence time for each predetermined attribute of the alarm, and outputs the alarm occurrence time or the ratio of the alarm occurrence time in a manner that allows distinction for each attribute, thereby enabling a more accurate understanding of the workload of medical personnel.

[0072] Furthermore, the vital alarms and technical alarms are each associated with specific information that identifies the subject of the biological information, and based on the specific information, the sum of the alarm occurrence times during which at least one of the vital alarms and technical alarms occurred, or the proportion of said sum, is calculated for each group to which the subject belongs, and the calculated sum of the alarm occurrence times or the proportion of said sum is output for the specified group. This makes it possible to accurately grasp the workload of a group whose workload is desired to be grasped.

[0073] Furthermore, the technical alarm is at least one of an alarm that notifies an abnormality in a measuring device for vital information, an abnormality in the state in which a sensor is attached to a subject, and an abnormality in the measuring environment for vital information. This makes it possible to easily and efficiently grasp the workload of medical staff and the like due to alarms.
