Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1 FIG.
In FIG. 1, the example of a structure of the sleep time management system which concerns on Embodiment 1 of this invention is shown. The sleep time management system according to Embodiment 1 includes a wearable device 100, a target person terminal 200, a management apparatus 300, and an administrator terminal 500.

  The management device 300 is a sleep time management device that manages the sleep time of a person to be managed (hereinafter simply referred to as “target person”). The management apparatus 300 is communicably connected to the target person terminal 200 and the administrator terminal 500 via the communication network 400.

  FIG. 2 shows an example of the configuration of the management apparatus 300. The management device 300 has a configuration as a known computer, and includes a processor 910 that performs processing such as computation, and a storage device 920 that stores information. The processor 910 is, for example, a CPU (Central Processing Unit), and the storage device 920 includes, for example, a memory and an auxiliary storage device. A part of the memory may constitute a storage unit that stores information.

  The storage device 920 stores measurement information 11, reference information 12, subject information 13 and determination result information 14. The storage device 920 also stores a program (not shown), and this program causes the computer to function as the management device 300.

  In addition, the management device 300 includes an input interface 930 and an output interface 940. The input interface 930 includes, for example, a keyboard and mouse, a network interface, and the like. The output interface 940 includes, for example, a liquid crystal display, a printing device, a network interface, and the like.

  The target person terminal 200 is, for example, a computer used by the target person, and is configured by a PC, a smartphone, or the like. The target person terminal 200 is provided for each target person, for example. The administrator terminal 500 is a computer used by an administrator of a sleep time management system, for example. Alternatively, the administrator terminal 500 may be a computer used by a staff member (such as a manager) who manages the target person, or a plurality of administrator terminals 500 may be provided. The target person terminal 200 is communicably connected to the wearable device 100. Wearable device 100 has a wristwatch-like structure, for example, and is configured by a computer in which a sensor is embedded.

  The wearable device 100 and the subject terminal 200 are an example of a configuration of a sleep time information acquisition unit that acquires information about sleep time (sleep time information). The wearable device 100 has a function of acquiring information related to sleep time. This information may directly represent the sleep time, or may represent information (such as time series data of acceleration of each part of the body) used for calculating the sleep time. The wearable device 100 has an appropriate configuration for acquiring information related to sleep time. For example, a measuring device for directly measuring sleep time may be provided, or various sensors for acquiring vital data may be provided. As the vital data, acceleration of each part of the body, blood pressure, and the like can be used.

  The wearable device 100 has a function of transmitting acquired information or sleep time measured based on the acquired information to another computer (for example, the subject terminal 200). The target person terminal 200 has a function of receiving this information from the wearable device 100 and transmitting it to another computer (for example, the management apparatus 300).

  The management device 300 has a function of executing a sleep time determination process described later based on information about the sleep time received from the subject person terminal 200 and outputting a warning according to the result. The warning is output to the administrator terminal 500 via the communication network 400, for example. The administrator terminal 500 has a function of receiving and displaying a warning.

  FIG. 3 shows an example of the configuration of the measurement information 11. The measurement information 11 records sleep time for each of the subjects. In the example of FIG. 3, for each set of a subject ID that uniquely identifies the subject and a measurement date, the actual sleep time (measured or calculated actual sleep time) of the subject on that measurement date is Associated. Further, in the example of FIG. 3, the number of times the subject has awakened is associated with that day. Note that the unit of measurement date does not need to match the exact date, and may be from one afternoon to the next morning, for example. The time expression method can be arbitrarily designed, and the time may be directly recorded as shown, or the sleep time and the awake time may be recorded.

  A method for measuring the actual sleep time and the number of times of waking up can be appropriately designed by those skilled in the art based on known techniques. For example, using a multi-axis acceleration sensor, if the movement status of each part of the body exceeds a predetermined standard, it is determined that it is awake, otherwise it is determined that it is sleeping, the actual sleep time and the awake The number of times can be determined.

  FIG. 4 shows an example of the configuration of the reference information 12. The reference information 12 records a plurality of pieces of information serving as a reference for determining whether sleep is insufficient. The reference information 12 associates a reference ID that uniquely identifies a reference type with a reference sleep time corresponding to the reference. In the example of FIG. 4, information representing a work pattern corresponding to the reference ID is further associated.

  For example, the reference ID “K01” is a determination criterion for a subject engaged in a specific type of light work (for example, a work style with many desk works). The reference ID “K03” is a determination reference for a subject engaged in a specific type of heavy labor (for example, a work style in which the body is often moved). Further, the reference ID “K05” is a determination criterion for a target person engaged in a specific type of night shift (for example, a work pattern in which he / she works during night hours). In general, people who work hard may need longer sleep than those who work lightly, and in such cases it is not appropriate to use a uniform reference sleep time for all subjects. However, according to the first embodiment, different criteria can be appropriately defined according to the difference in work style.

  It is also possible to further subdivide the same type of work style. For example, in the example of FIG. 4, two reference IDs are defined for light labor, and different reference sleep times are set for each. This is useful when it is necessary to use different criteria depending on the age, sex, etc. of the subject.

  FIG. 5 shows an example of the configuration of the target person information 13. The target person information 13 associates a reference ID for each target person. In the example of FIG. 5, for each target person, a group to which the target person belongs and a notification destination are associated.

  In this embodiment, the notification destination “01” corresponds to the subject person, the notification destination “02” corresponds to the superior of the subject person, and the notification destination “03” corresponds to the occupational physician of the subject person. The notification destination “04” corresponds to the general affairs department of the target person's workplace, and the notification destination “05” corresponds to the project leader or team leader of the project to which the target person belongs. The notification destination may be any destination that can be notified as a function of the management apparatus 300. For example, the notification destination is represented by an e-mail address.

  The specific association format of the group and the notification destination can be arbitrarily designed. In the example of FIG. 5, a plurality of groups and a plurality of notification destinations may be associated with one target person, and notification destinations may be grouped and associated. For example, the target person with the target person ID “P123” and the target person with the target person ID “P789” belong to the same group “111”, but also to different groups “AAA” and “BBB”. belong to.

  FIG. 6 shows an example of the configuration of the determination result information 14. The determination result information 14 associates a determination result indicating whether or not each subject has sleep deprivation. In particular, in the example of FIG. 6, information on a measurement date (measurement date, actual sleep time, number of times awakened) determined to be insufficient for sleep is recorded. Furthermore, in the example of FIG. 6, a value obtained by subtracting the actual sleep time from the reference sleep time is recorded as the insufficient sleep time.

The operation of the management apparatus 300 having the above configuration will be described below.
First, the management device 300 records the reference information 12 and the target person information 13 (for example, stores them in the storage device 920). That is, the management device 300 records a plurality of reference sleep times included in the reference information 12. Moreover, the management apparatus 300 records one of the reference sleep times in association with each target person via the reference information 12 and the target person information 13. In addition, the management apparatus 300 records one or more notification destinations in association with each target person. These pieces of information may be updated at any time.

  FIG. 7 is a flowchart for explaining the operation of the management apparatus 300 regarding the sleep shortage determination process. The process in FIG. 7 is executed for each target person. Moreover, the process of FIG. 7 is performed for every measurement date, for example.

  First, the management apparatus 300 acquires the actual sleep time of a specific measurement date and the number of times of waking up for a specific subject (Step S1). This acquisition may be performed in any way, but can be received from the target person terminal 200 via the communication network 400, for example. The management device 300 records the acquired actual sleep time and the number of times of waking up in the measurement information 11 in association with the subject ID and the measurement date.

  Next, the management apparatus 300 acquires a reference ID associated with the target person (step S2). This process is performed with reference to the target person information 13, for example. Next, the management apparatus 300 acquires the reference sleep time associated with the reference ID (step S3). This process is performed with reference to the reference information 12, for example.

  Next, the management apparatus 300 determines whether or not the subject is deficient in sleep based on the actual sleep time acquired in step S1 and the reference sleep time acquired in step S3. Step S4, sleep deprivation determination function). The specific processing of this determination can be arbitrarily designed. For example, the actual sleep time is compared with the reference sleep time, and if the actual sleep time is shorter than the reference sleep time, it is determined that sleep is insufficient. It can be configured to determine that sleep is not insufficient.

  In the present specification, “insufficient sleep” is not limited to sleep insufficiency defined in a medically strict sense, but may broadly mean a state in which the quality or amount of sleep falls below some standard. In the first embodiment, as described above, it is defined that sleep is insufficient when the actual sleep time is simply shorter than the reference sleep time. Further, different embodiments or modifications may be used with different meanings.

  When it is determined that sleep is insufficient, the management device 300 outputs a warning (step S5, warning function). Although the warning output destination can be arbitrarily designed, in the present embodiment, the warning is output to the notification destination of the subject who is determined to be lack of sleep. Although the warning output mode can be arbitrarily designed, in the present embodiment, it is transmitted via the communication network 400 in the form of an e-mail. The e-mail includes, for example, a subject ID (or other information that can identify the subject), a measurement date, an actual sleep time, a reference sleep time, and a warning display indicating that sleep is determined to be insufficient. Thereafter, the process of FIG. 7 ends.

  If it is determined that the sleep is not insufficient, step S5 is not executed, and the process of FIG. 7 ends.

  Although not shown in FIG. 7, the warning output from the management apparatus 300 is received and output by the administrator terminal 500, for example. As a specific example, the information is displayed on the display device when the administrator performs an email browsing operation using the administrator terminal 500. Thereby, the administrator can know that any one of the subjects is in a state of sleep deprivation, and can take measures as necessary.

As described above, according to the management device 300 according to Embodiment 1 of the present invention, a plurality of reference sleep times are defined in the reference information 12, and one of the reference sleep times is selected and associated for each target person. Therefore, it is possible to determine the subject's lack of sleep based on a standard adapted to each individual.
In the reference information 12 illustrated in FIG. 4, the reference sleep time corresponding to the work style is associated with the reference ID, but the parameters that determine the reference sleep time are not the work form, but gender, age, or a combination thereof. A reference sleep time may be associated.
Moreover, only reference | standard ID and reference | standard sleep time may be linked | related as the reference | standard information 12, and you may comprise so that reference | standard ID may be set for every subject ID. In this case, for example, using the target person terminal 200 or the administrator terminal 500, an input from the target person or the administrator is accepted, and the result is stored as a reference ID for each target person ID of the target person information 13. By comprising in this way, the reference sleep time considered appropriate for every subject can be set, without using a parameter.

  In addition, since a warning notification destination can be arbitrarily designated, it is easier to take appropriate measures. For example, if the person is included in the notification destination, the person can be aware and take a long sleep. In addition, if the manager is included in the notification destination, it will be easier to improve the fundamental working environment. In addition, when there is a change in organization or the like, the notification destination can be appropriately changed by updating the target person information 13.

  Further, for example, the business owner can manage the health of employees more finely. In the conventional technology, since the health management is performed based on the health check once a year and the work management in units of three months, the daily state cannot be managed, but the management according to the first embodiment Since the apparatus 300 records and determines the actual sleep time in units of dates, more detailed management is possible.

Embodiment 2. FIG.
The second embodiment is modified to determine whether or not there is a tendency for insufficient sleep when it is determined in the first embodiment that the sleep is not insufficient. Hereinafter, differences from the first embodiment will be described.

  FIG. 8 is a flowchart for explaining a part of the operation of the management apparatus according to the second embodiment. In the second embodiment, the processes in steps S1 to S3 are performed in the same manner as in FIG. After step S3, the management device determines whether the subject being processed is “insufficient to sleep”, “not sleep insufficient, but tends to lack sleep”, or “insufficient to sleep” It is determined whether or not there is no tendency for lack of sleep (step S4a, sleep lack determination function).

  Although the specific process of determination in step S4a can be designed arbitrarily, it may be configured as follows as a specific example. If the actual sleep time is shorter than the reference sleep time by 2 hours or more, it is determined that the sleep is insufficient, and otherwise, it is determined that the sleep is not insufficient. When it is determined that the sleep is not insufficient, if the actual sleep time is shorter than the reference sleep time, it is determined that there is a tendency for lack of sleep. Otherwise, it is determined that there is no tendency for lack of sleep. If it is determined that sleep is insufficient, the management apparatus executes step S5 and outputs a warning in the same manner as in the first embodiment.

  When it is determined that “it is not sleep deprivation but there is a tendency for sleep deprivation”, the management device determines whether or not the tendency for sleep deprivation continues chronically (step S6). The specific processing of this determination can be arbitrarily designed. For example, when it is determined that the subject has a tendency to lack sleep or is lacking sleep for a predetermined number of times within a predetermined period, It is determined that the tendency of shortage continues chronically. As a specific example, when it is determined that there is a tendency for lack of sleep or lack of sleep in 50% or more (that is, 15 days or more) of the determination in the past 30 days from the latest measurement date, the tendency for lack of sleep Is determined to continue chronically.

  When it is determined that the tendency for lack of sleep continues chronically, the management device outputs a warning (step S7, warning function). The warning is output in the same manner as in step S5, for example, but the content of the warning display may be different from that in step S5. For example, in the e-mail, it is determined that the subject ID (or other information that can identify the subject), the measurement date, the actual sleep time, the reference sleep time, and the tendency of lack of sleep continue chronically. A warning message to the effect is included. Thereafter, the process ends.

  When it is determined that the tendency for lack of sleep does not continue chronically, step S7 is not executed, and the process ends.

  As described above, according to the management device according to the second embodiment of the present invention, in addition to the effects obtained by the first embodiment, it is possible to make a determination from a longer-term viewpoint. It can correspond to the appearance form.

Embodiment 3 FIG.
The third embodiment is a modification of the first or second embodiment that outputs the ratio of subjects determined to be sleep deprived. Hereinafter, differences from the first and second embodiments will be described.

  In step S5 or S7, the management device according to the third embodiment has a lack of sleep among the target persons associated with the notification destination for each of the notification destinations of the target person being processed (if there are a plurality of the destinations). The ratio of the judged target person is output. For example, when a specific notification destination in the target person information 13 is associated with 100 target persons, and 30 target persons are determined to have insufficient sleep, a ratio of 30% is part of the warning. Is notified to the notification destination. This ratio is included in an e-mail representing a warning and transmitted, for example.

  Therefore, for example, if a person in charge of a department (such as a manager) is defined as a notification destination for all employees in a department, the person in charge can easily grasp the sleep status of the department as a whole. .

  As described above, according to the management device according to the third embodiment of the present invention, in addition to the effects obtained by the first or second embodiment, it is possible to more easily grasp the overall situation in the group unit, Appropriate measures can be taken.

  In particular, in a group of employees engaged in specific tasks such as projects, the physical condition of many employees may deteriorate all at once due to reasons such as the project entering a busy season. According to the management device according to the third embodiment, if the notification destinations of employees belonging to such a group are specified to be the same, the sleeping time is reduced overall within the group by transmitting the ratio. Since it is possible to grasp at an early stage, it is possible to detect signs of simultaneous physical deterioration at an early stage, and to appropriately take preventive measures or preventive measures.

  The ratio calculation standard can be designed arbitrarily. For example, instead of the ratio of subjects determined to be sleep deprived, the ratio of subjects who are determined not to be sleep deprived but tend to lack sleep may be used, or both of these may be used, You may use these sums.

Embodiment 4 FIG.
The fourth embodiment is a modification of the first to third embodiments so that the management apparatus selects an appropriate standard for each target person. Hereinafter, differences from the first to third embodiments will be described.

  FIG. 9 shows an example of the configuration of the management apparatus 301 according to the fourth embodiment. The storage device 920 of the management device 301 stores the reference determination information 15 in addition to the information stored in the management device 300 according to the first embodiment.

  FIG. 10 is a flowchart for explaining the operation of the management apparatus 301 related to the criterion determination process. The process of FIG. 10 is performed for each target person. The execution timing of the processing in FIG. 10 can be arbitrarily designed, but may be executed immediately before the processing in FIG. 7, for example, or regularly (for example, once a month) regardless of the processing timing in FIG. May be executed.

  In the process of FIG. 10, first, the management device 301 acquires information representing the exercise state of a specific target person (step S11). The information indicating the exercise state is, for example, time series data of acceleration of each part of the body and time series data of blood pressure and other vital data.

  Next, the management apparatus 301 selects the reference sleep time associated with the subject based on the exercise state of the subject and the reference determination information 15 (step S12). The specific process of this selection can be appropriately designed based on a known technique or the like. For example, in the criterion determination information 15, different criterion IDs are associated for each range of exercise amount, the reference ID of the range corresponding to the exercise amount acquired in step S <b> 11 is referenced, and the reference sleep time corresponding to the reference ID is selected. You may comprise as follows.

For example, in the criterion determination information 15, a reference ID corresponding to light labor 1 may be associated with a subject having a small amount of exercise, and a reference ID corresponding to heavy labor 1 may be associated with a subject having a large amount of exercise. In this way, the management device 301 determines the reference sleep time for each subject.
Further, the information representing the exercise state may be a blood pressure level, a blood pressure fluctuation amount, or the like. When the blood pressure is higher than the reference value or when the fluctuation amount of the blood pressure is larger than the reference fluctuation amount, it is considered that sleep should be taken more, so the reference sleep time can be set longer.

  As described above, according to the management device 301 according to the fourth embodiment of the present invention, in addition to the effects obtained by the first to third embodiments, an appropriate criterion can be automatically selected for each target person.

In the above-described first to fourth embodiments, the following modifications can be made.
In the target person information 13, information regarding the notification destination may be omitted. In that case, relevant information may be output by screen display or the like on the administrator terminal 500 for all subjects determined to be sleep deprived.

  In determining whether sleep is insufficient in step S4, S4a, or S6, other information may be considered. For example, the determination may be made based on the number of times of waking up in addition to the actual sleep time and the reference sleep time. Moreover, sleep may be classified into shallow sleep and deep sleep, and determination may be made in more detail. For example, the wearable device 100 and the subject terminal 200 are configured so as to be able to distinguish and measure the actual sleep time due to shallow sleep and the actual sleep time due to deep sleep. It may be defined separately from the time by. In that case, the process of step S4, S4a, or S6 can be performed about at least one of the time by shallow sleep or the time by deep sleep. As a specific example, it may be configured to determine that sleep is insufficient if deep sleep time is insufficient regardless of shallow sleep time.

  The structural unit of hardware can be arbitrarily changed. For example, two or all of the target person terminal 200, the management apparatus 300, and the administrator terminal 500 may be configured using a single computer.
