Abstract

This monitoring-subject monitoring system is equipped with a storage unit, an identification unit, a determination unit, and a first display control unit. The storage unit stores, in advance, imaging data obtained by capturing the sleeping state of a monitoring subject for a prescribed time interval, and measurement data obtained by measuring the amount which the sleeping subject moves concurrently with the imaging for the prescribed time interval. By using the imaging data and the measurement data, the identification unit identifies an active time period, which is a time period when the movement amount exceeds a prescribed amount, and also identifies a still time period, which is a time period when the movement amount is no greater than the prescribed amount, along the imaging data time axis. The determination unit determines the sleeping posture, which is the posture in which the monitoring subject is sleeping during the still time period. The first display control unit displays the sleeping posture determined by the determination unit on a display unit.

Description

Monitored person monitoring system and monitored person monitoring method

The present invention relates to a monitored person monitoring system that monitors, for example, a person who needs nursing or a person who needs care (hereinafter referred to as a nurse who needs care) as a monitoring target, and a method applied to this system. .

Japan (Japan) is an aging society, more specifically the ratio of population over 65 years old to the total population due to the improvement of living standards accompanying the post-war high economic growth, improvement of sanitary environment and improvement of medical standards, etc. It is a super-aging society with an aging rate exceeding 21%. In 2005, the total population was about 126.5 million, while the elderly population over the age of 65 was about 25.56 million. In 2020, the total population was about 124.11 million. There is also a prediction that the elderly population will be about 34.56 million. In such an aging society, an increase in the number of nurses requiring medical attention due to illness, injury, aging, etc. is expected, compared to a normal society that is not an aging society.

Such nurses are required to enter and receive nursing and nursing care at facilities such as hospitals and welfare facilities for the elderly (Japanese elderly law short-term entrance facilities, nursing homes for the elderly and special nursing homes for the elderly, etc.). In facilities such as hospitals and welfare facilities for the elderly, for example, those who need nursing care such as nurses or caregivers, etc. Nurses, etc.) confirm their safety by periodically patrols. However, since the number of nurses and the like is reduced in the quasi-night shift and night shift hours compared to the day shift hours, the work load per person increases, and therefore the work load must be reduced. For this reason, in recent years, a monitored person monitoring device that monitors (monitors) a patient who needs nursing is monitored and developed.

Some nurses in hospitals and welfare facilities for the elderly have difficulty in turning over on the bed, and nurses are difficult to turn over to prevent bed slipping. If necessary, it is necessary to change the sleeping posture for the nurses who need it. Even a nurse who needs to be able to turn over may have a bed slip when sleeping for a long time in a specific posture (for example, on his back). Therefore, nurses and the like work to change the sleeping posture as necessary for such nurses and the like.

¡People who are sleeping include supine, sideways, and prone. When changing the sleeping posture for a nurse or the like, it is necessary to manage the sleeping posture so as not to concentrate on a specific posture (for example, on the back). It is a burden for nurses and the like to visit nurses' rooms regularly to check and record their sleeping posture.

[Recording the sleeping posture of a nurse or the like using a device that can automatically detect the sleeping posture of a person can reduce the burden on the nurse or the like. As such a device, there are a contact type attached to a person and a non-contact type attached to a person. If a nurse or the like needs dementia, the device may be removed without permission. For this reason, the non-contact type is preferable in the case of a nurse who needs care.

As a non-contact type, for example, there is a biological information acquisition device disclosed in Patent Document 1. This biological information acquisition apparatus extracts a respiratory component included in a microwave detected by a detection unit that irradiates a subject with a microwave and detects the microwave reflected by the subject, and the detection unit. An extraction unit; and a determination unit that determines a body position (a supine position, a lateral direction, and a prone position) during sleep based on the signal intensity of the respiratory component extracted by the extraction unit.

The body type of the nurses etc. The time interval for changing the sleeping posture, the posture to be changed next, and the like are different. In order to reduce the burden on nurses and the like at a nursing care site where a single nurse or the like cares for many nurses requiring nursing care, a technique capable of supporting the management of the posture of the nurses and the like who are sleeping is desired.

The monitored person monitoring system in the embodiment is a system that uses a plurality of devices to monitor a monitored person (monitoring target) that is a monitoring target (monitoring target) to be monitored (to be monitored), and a terminal device, And a monitored person monitoring device that is connected to the terminal device so as to be communicable, detects a predetermined event related to the monitored person, and notifies the terminal device of the event. The monitored person monitoring device may be integrally configured by a single device, but in this embodiment, the monitored person monitoring device is connected to the sensor device and the sensor device and the terminal device so as to communicate with each other. By providing the management server device (central processing unit), the two types of devices are configured separately. This sensor device detects the predetermined event related to the monitored person and notifies (notifies and transmits) the management server device. Upon receiving the notification from the sensor device, the management server device manages the event that has received the notification, and re-notifies the event to a predetermined terminal device associated with the sensor device. Send. Although the terminal device may be one type of device, in the present embodiment, the terminal device is two types of devices, a fixed terminal device and a mobile terminal device. The main difference between these fixed terminal devices and portable terminal devices is that the fixed terminal device is fixedly operated, while the portable terminal device is operated by being carried by a supervisor (user) such as a nurse or a caregiver. Since the fixed terminal device and the mobile terminal device are substantially the same, in the following embodiments, the mobile terminal device will be mainly described.

FIG. 1 is a diagram illustrating a configuration of a monitored person monitoring system MS in the embodiment. FIG. 2 is a diagram showing the configuration of the management server device SV in the monitored person monitoring system MS shown in FIG. FIG. 3 is a diagram showing a configuration of the mobile terminal device TA in the monitored person monitoring system MS shown in FIG.

More specifically, such a monitored person monitoring system MS includes, for example, as shown in FIG. 1, one or a plurality of sensor devices SU (SU-1 to SU-4), a management server device SV, A fixed terminal device SP, one or a plurality of portable terminal devices TA (TA-1, TA-2), and a private branch exchange (PBX, Private Branch eXchange) CX, which are wired or wireless, LAN (Local) It is connected to be communicable via a network (network, communication line) NW such as Area Network. The network NW may be provided with repeaters such as repeaters, bridges, and routers that relay communication signals. In the example shown in FIG. 1, the plurality of sensor devices SU-1 to SU-4, the management server device SV, the fixed terminal device SP, the plurality of portable terminal devices TA-1, TA-2, and the private branch exchange CX include an L2 switch. Are connected to each other by a wired / wireless LAN (for example, a LAN in accordance with the IEEE 802.11 standard) NW including the LS and the access point AP. More specifically, the plurality of sensor devices SU-1 to SU-4, the management server device SV, the fixed terminal device SP, and the private branch exchange CX are connected to the line concentrator LS, and the plurality of portable terminal devices TA-1, TA-2. Is connected to the line concentrator LS via the access point AP. The network NW configures a so-called intranet by using Internet protocol groups such as TCP (Transmission Control Protocol) and IP (Internet Protocol).

The monitored person monitoring system MS is arranged at an appropriate place according to the monitored person Ob. The monitored person (person to be watched) Ob is, for example, a person who needs nursing due to illness or injury, a person who needs care due to a decrease in physical ability, a single person living alone, or the like. In particular, from the viewpoint of enabling early detection and early action, the monitored person Ob may be a person who needs the detection when a predetermined inconvenient event such as an abnormal state occurs in the person. preferable. For this reason, the monitored person monitoring system MS is suitably arranged in a building such as a hospital, a welfare facility for the elderly, and a dwelling unit according to the type of the monitored person Ob. In the example illustrated in FIG. 1, the monitored person monitoring system MS is disposed in a building of a care facility that includes a plurality of rooms RM in which a plurality of monitored persons Ob live and a plurality of rooms such as a nurse station.

The sensor device SU is disposed so as to be able to monitor a space (location space, in the example shown in FIG. 1, the room RM of the installation location) where the monitored person Ob is scheduled, and above the location space as a subject of photographing. The image (image data) overlooking the shooting target is generated, and the image (target image) of the shooting target is output to the management server device SV. Preferably, since there is a high probability that the entire monitored person Ob can be photographed, the sensor device SU is expected to be located at the head of the monitored person Ob in the bedding on which the monitored person Ob is lying (for example, a bed). It is arranged so that the object to be photographed can be photographed from directly above the preset planned head position (usually the position where the pillow is disposed). With this imaging function, the sensor device SU acquires an image of the monitored person Ob taken from above the monitored person Ob, preferably an image taken from directly above the planned head position.

FIG. 1 shows four first to fourth sensor devices SU-1 to SU-4 as an example, and the first sensor device SU-1 is one of the monitored persons Ob. The second sensor device SU-2 is arranged in a room RM-2 (not shown) of Mr. B Ob-2 who is one of the monitored persons Ob.

It is a device that manages information related to monitoring Ob (monitoring information). When the management server device SV receives the first event notification communication signal from the sensor device SU as the event notification, the management server device SV relates to the monitoring of the monitored person Ob based on each information accommodated in the first event notification communication signal. A predetermined terminal device that stores (records) monitoring information and associates a communication signal (second event notification communication signal) containing the monitoring information related to monitoring of the monitored person Ob in advance with the sensor device SU. Send to SP, TA. For this purpose, the management server device SV indicates the notification destination (re-notification destination, re-notification destination, transmission destination) such as the first event notification communication signal transmitted from the sensor device SU and the notification of the sensor ID that is the transmission source. The correspondence relationship (notification destination correspondence relationship) with the terminal ID (re-notification destination) and the communication address thereof are stored. The terminal ID (terminal device identifier) is an identifier for identifying and identifying the terminal devices SP and TA. Then, the management server device SV provides the client with data corresponding to the request of the client (in this embodiment, the fixed terminal device SP and the portable terminal device TA). Such a management server device SV can be configured by, for example, a computer with a communication function.

Referring to FIG. 1, fixed terminal device SP inputs a communication function for communicating with other devices SU, SV, TA via network NW, a display function for displaying predetermined information, and predetermined instructions and data. Monitored person by inputting a predetermined instruction or data to be given to the management server device SV or the portable terminal device TA, displaying monitoring information obtained by the sensor device SU, etc. It is a device that functions as a user interface (UI) of the monitoring system MS. Such a fixed terminal device SP can be configured by, for example, a computer with a communication function. The fixed terminal device SP as an example of the terminal device operates in the same manner as the mobile terminal device TA. However, in this specification, a mobile terminal device TA that is another example of the terminal device will be described.

The mobile terminal device TA has a communication function for communicating with other devices SV, SP, SU via the network NW, a display function for displaying predetermined information, an input function for inputting predetermined instructions and data, and a voice call. A monitoring function (including moving images) obtained by the sensor device SU by inputting a predetermined instruction or data to be provided to the management server device SV or the sensor device SU, or by notification from the management server device SV. This is a device for displaying or making a nurse call response or calling by voice call with the sensor device SU.

Referring to FIG. 3, the mobile terminal device TA includes a display unit 36, a display control unit 37 (first display control unit, second display control unit), and an input unit 38 as functional blocks. The display unit 36 is realized by a liquid crystal display or the like. The display control unit 37 performs control to display an image (moving image) on the display unit 36. The display control unit 37 is realized by a combination of a CPU, a RAM, a ROM, and the like. The input unit 38 is a device for inputting a command or the like for operating the mobile terminal device TA. The input unit 38 is realized by a keyboard, a mouse, a touch panel, or the like.

The monitored person monitoring system MS in the present embodiment has a function of supporting the management of the posture where the monitored person Ob is using the photographing data D1 (FIG. 2) and the measurement data D2 (FIG. 2). The photographing data D1 is data obtained by performing photographing for a predetermined time to photograph a state in which the monitored subject Ob to be monitored is sleeping. The measurement data D2 is data obtained by executing the measurement of the amount of movement of the monitored person Ob who is sleeping for a predetermined time in parallel with the imaging in the state where the monitored person Ob is sleeping. The predetermined time is, for example, 24 hours. As a premise for executing the above function, the monitored person monitoring system MS acquires the photographing data D1 and the measurement data D2 and stores them in the storage unit 31. This will be described.

Referring to FIGS. 1 and 2, the sensor device SU captures a moving image of the monitored person Ob while the monitored person Ob is sleeping, and transmits the moving image data to the management server apparatus SV. The shooting time is a predetermined time (for example, 24 hours). The management server device SV stores the transmitted moving image data in the storage unit 31 as shooting data D1.

The motion amount calculation unit 21 calculates the amount of motion of the person being monitored Ob using the captured data D1 in parallel with the capturing of the moving image by the sensor device SU. More specifically, for example, the motion amount calculation unit 21 calculates a difference between the current frame and, for example, a frame five seconds before, among the frames constituting the shooting data D1 (moving image data), and the pixel value is The sum of different pixels is calculated, and this sum is taken as the amount of motion. As described above, the sensor device SU and the motion amount calculation unit 21 function as a measurement unit that measures the motion amount of the person to be monitored Ob who is sleeping.

The measurement unit sequentially measures the amount of movement of the monitored person Ob. For example, the amount of motion is measured every predetermined time (for example, every 5 seconds). This sequentially measured data becomes measurement data D2. The management server device SV stores the measurement data D2 in the storage unit 31.

The storage unit 31 stores photographing data D1 and measurement data D2 for each monitored person Ob. Specifically, the shooting data D1 and measurement data D2 of the monitored person Ob-1 shown in FIG. 1, the shooting data D1 and measurement data D2 of the monitored person Ob-2, and the shooting data D1 of the monitored person Ob-3 are shown. The measurement data D2 and the imaging data D1 and measurement data D2 of the monitored person Ob-4 are stored in the storage unit 31.

The reproduction of the image indicated by the shooting data D1 will be described. FIG. 4 is an explanatory diagram for explaining this. FIG. 4 includes two graphs. The horizontal axis of the graph indicates time, and the vertical axis indicates the amount of motion. The amount of movement is the amount of movement of the monitored person Ob who is sleeping, which is indicated by the measurement data D2. The upper graph shows a case where the monitored person Ob is thin, and the lower graph shows a case where the monitored person Ob is fat.

The time zone in which the amount of motion exceeds a predetermined threshold (predetermined amount) is the operating time zone. A time zone in which the amount of motion is equal to or less than a predetermined threshold is a stationary time zone. Accordingly, the time axes of the two graphs in FIG. 4 are an operation time zone (operation time zone T2, T4, T6,...) And a stationary time zone (stationary time zones T1, T3, T5,...). It is divided into. The operation time zone and the stationary time zone are alternately arranged in time series. A thin person's threshold TH1 (predetermined threshold) is smaller than a fat person's threshold TH2 (predetermined threshold). People who are thin have a higher risk of bedsores than those who are fat, so detailed observation is necessary. Therefore, a thin person has a predetermined threshold value smaller than a fat person.

The posture (sleeping posture) of the monitored person Ob includes a supine position, a prone position, a left lateral direction, and a right lateral direction. The sleeping posture indicated by the symbol (↑) shown in FIG. 4 indicates the supine position, the sleeping posture indicated by the symbol (↓) indicates prone, the sleeping posture indicated by the symbol (←) indicates the left lateral orientation, and the symbol (→ The sleeping posture indicated by () indicates the right lateral orientation.

With reference to FIG. 1 and FIG. 4, an image (moving image) indicated by the user (for example, the supervisor NS) of the monitored person monitoring system MS using the mobile terminal device TA or the fixed terminal device SP as the captured data D1. (Moving image indicated by data) is reproduced at the reproduction speed in the operation time zone in the operation time zone of the monitored person Ob, and is reproduced at the reproduction speed in the stationary time zone in the stationary time zone of the monitored person Ob. . The playback speed in the operating time zone is faster than the playback speed in the stationary time zone.

FIG. 5 is a flowchart for explaining the reproduction of the photographing data D1 in the monitored person monitoring system MS in the present embodiment. The monitored person Ob is the monitored person Ob-1 shown in FIG. The terminal device is assumed to be a portable terminal device TA-1 shown in FIG. The predetermined threshold is the threshold TH1 shown in FIG. The measurement data D2 is the measurement data of the upper graph shown in FIG. The reproduction of the image indicated by the shooting data D1 is reproduction of a moving image. As will be described later, the reproduction of the image indicated by the photographing data D1 may be slide reproduction.

Referring to FIGS. 1 and 5, the supervisor NS-1 operates the portable terminal device TA-1 and inputs a command for reproducing the image of the monitored person Ob-1 in the sleeping state (step S11). ). The portable terminal device TA-1 transmits the input command to the management server device SV, and the management server device SV receives the transmitted command.

Thereby, with reference to FIG. 2 and FIG. 5, the specifying unit 32 reads out the photographing data D1 and the measurement data D2 of the monitored person Ob-1 from the storage unit 31. The specifying unit 32 sets a time zone in which the motion amount of the monitored person Ob-1 exceeds the threshold value TH1 as an operation time zone, a time zone in which the motion amount is equal to or less than the threshold value TH1, as a stationary time zone, and sets the monitored person Ob-1 The operation time zone and the stationary time zone are specified on the time axis of the shooting data D1 using the shooting data D1 and the measurement data D2 (step S12). The time axis is the time indicated by the horizontal axis of the graph shown in FIG. As described above, as shown in FIG. 4, the stationary time zone T1, the operating time zone T2, the stationary time zone T3, the operating time zone T4,..., The stationary time zone T17, and the operating time zone T18 are specified.

The determination unit 25 reads out the photographing data D1 of the monitored person Ob-1 from the storage unit 31, and uses this photographing data D1 to determine the posture (sleeping posture) of the monitored person Ob-1 in the stationary time zone. Determination is made (step S13).

An example of how to determine the sleeping posture will be described. 6 to 9 are schematic views showing a state where the monitored person Ob is sleeping, FIG. 6 shows a case where the sleeping posture is supine, FIG. 7 shows a case where the sleeping posture is prone, 8 shows a case where the sleeping posture is right sideways, and FIG. 9 shows a case where the sleeping posture is left sideways.

6 to 9, the monitored person Ob is sleeping on the bed 41, and a futon 45 is put on the body other than the head of the monitored person Ob. Reference numeral 43 indicates a pillow. The determination unit 25 (FIG. 2) focuses on the skin color area 51 and the hair color area 53 of the head of the monitored person Ob and determines the sleeping posture of the monitored person Ob. The skin color area 51 is an area of the face of the monitored person Ob. The color of the skin color area 51 is the skin color of the face of the monitored person Ob. The hair color region 53 is a region where the hair of the head of the monitored subject Ob grows. The color of the hair color area 53 is the color of the hair of the head of the monitored person Ob. The determination unit 25 extracts the image area of the head of the monitored person Ob using the shooting data D1 in the still time period. For example, by the Hough transform of a circle or an ellipse, for example, by pattern matching using a head model prepared in advance, or by, for example, a neural network learned for head detection, The image area of the head is extracted. Next, the determination unit 25 extracts the skin color area 51 and the hair color area 53 in the extracted image area. These areas can be distinguished by color.

The determination unit 25 determines that the sleeping posture of the monitored person Ob is right sideways if the hair color area 53 is present in the most left part of the image area of the head of the monitored person Ob (FIG. 8). In the image area of the head of the monitored person Ob, the determination unit 25 determines that the sleeping position of the monitored person Ob is the left side when the hair color area 53 is present in the most right part (FIG. 9). If the skin color area 51 is larger than the hair color area 53 in the image area of the head of the monitored person Ob, the determination unit 25 does not correspond to either the right side orientation or the left side orientation. The face is determined to be on the back (FIG. 6). If the hair color area 53 is larger than the skin color area 51 in the image area of the head of the monitored person Ob, the determination unit 25 does not correspond to either the right side orientation or the left side orientation. It is determined to be prone (FIG. 7).

Note that the technique of Patent Document 1 described in the background art may be used to determine the sleeping posture.

2 and 4, the determination unit 25 generates sleeping posture information indicating the sleeping posture determined in step S13. The sleeping posture information includes information indicating the sleeping posture in the stationary time zone T1 (left lateral direction), information indicating the sleeping posture in the stationary time zone T3 (upward), information indicating the sleeping posture in the stationary time zone T5 (left lateral orientation), .. and information indicating the sleeping posture in the stationary time zone T17 (upward).

The reproduction data generation unit 33 uses the photographic data D1 of the monitored person Ob-1 as the photographic data in the stationary time zone T1, the photographic data in the operating time zone T2, the photographic data in the stationary time zone T3, and the photographic data in the operating time zone T4. ... Reproduction in which the shooting data in the stationary time zone T17 and the shooting data in the operation time zone T18 are identifiable (for example, an index is added), and the sleeping posture information is added to the shooting data D1. Generate data.

Referring to FIGS. 1 and 5, management server apparatus SV transmits the reproduction data to portable terminal apparatus TA-1. The portable terminal device TA-1 receives the reproduction data, and the display control unit 37 (FIG. 3) of the portable terminal device TA-1 starts reproduction of the reproduction data (step S14).

Referring to FIGS. 3 to 5, display control unit 37 of portable terminal device TA-1 sets time zone order n to the first (step S15). The display control unit 37 determines whether the first time zone is an operating time zone or a stationary time zone (step S16). Since the first time zone is the still time zone T1, the display control unit 37 causes the display unit 36 to display the moving image of the still time zone T1 at the reproduction speed in the still time zone (step S17).

The display control unit 37 displays the sleeping posture (left side orientation) in the stationary time zone T1 on a part of the display unit 36 when the moving image of the stationary time zone T1 is displayed on the display unit 36. The sleeping posture is displayed with characters, icons, and the like. Note that the display control unit 37 sleeps from the first stationary time zone to the last stationary time zone (sleeping posture in the stationary time zone T1, sleeping posture in the stationary time zone T3, sleeping posture in the stationary time zone T5. ,... May be displayed on the display unit 36 in a lump as a sleeping posture history.

The display control unit 37 determines whether or not the video reproduction in the nth time zone has ended (step S19). Here, the display control unit 37 determines whether or not the moving image reproduction in the first time zone (still time zone T1) has ended.

When the display control unit 37 determines that the video reproduction of the nth time zone has not ended (No in step S19), the process of step S19 is repeated. When the display control unit 37 determines that the video playback in the nth time zone has ended (Yes in step S19), the display control unit 37 finishes the video playback in the last time zone (operation time zone T18). Whether or not (step S20). Here, since the video playback in the first time zone (stationary time zone T1) has been completed (No in step S20), the display control unit 37 increases the order n of the time zones by one (step S21). The process of S16 is performed.

In step S16, the display control unit 37 determines whether the nth time zone is an operating time zone or a stationary time zone. Here, since the nth time zone is the second time zone (operation time zone T2), the display control unit 37 displays the moving image of the operation time zone T2 on the display unit 36 at the playback speed in the operation time zone. It is displayed (step S18).

The display control unit 37 determines whether or not the video reproduction in the nth time zone has ended (step S19). Here, the display control unit 37 determines whether or not the moving image reproduction in the second time zone (operation time zone T2) has ended.

When the display control unit 37 determines that the reproduction of the nth time zone has not ended (No in step S19), the process of step S19 is repeated. When the display control unit 37 determines that the video playback in the nth time zone has ended (Yes in step S19), the display control unit 37 finishes the video playback in the last time zone (operation time zone T18). Whether or not (step S20). When the moving image reproduction in the operating time period T18 is completed (Yes in step S20), the display control unit 37 ends the moving image reproduction indicated by the shooting data D1 of the monitored person Ob-1.

It is important to grasp the correct sleeping posture in order to prevent the floor slip of the monitored person Ob. The display control unit 37 displays the sleeping posture of the monitored person Ob in the stationary time zone on the display unit 36 when the moving image is reproduced in the stationary time zone (step S17). Therefore, the supervisor NS can confirm the sleeping posture of the monitored person Ob in the stationary time period while confirming the body movement of the monitored person Ob in the operation time period.

As described above, the display control unit 37 can cause the display unit 36 to display the sleeping posture history from the first stationary time period to the last stationary time period. Thereby, the supervisor NS can know the past sleeping posture and the time when the sleeping posture is determined by looking at the history of the sleeping posture. Therefore, when the supervisor NS next changes the sleeping posture of the monitored person Ob, it is used as a reference for determining the timing to change to the next sleeping posture and determining which sleeping posture the next sleeping posture should be. can do.

This embodiment has the following functions 1 to 5.

The function 1 will be described. With reference to FIG. 3 and FIG. 4, the operation time zone is a time zone in which the motion amount sequentially measured exceeds a predetermined threshold value in a predetermined time. The predetermined time is a period (for example, 24 hours) during which the state where the monitored person Ob is sleeping is photographed. The amount of motion measured sequentially is, for example, the amount of motion measured every 5 seconds. The predetermined threshold is, for example, the threshold TH1 or the threshold TH2.

The monitored person monitoring system MS further includes a first input unit, and the specifying unit 32 (FIG. 2) is input when a value serving as a predetermined threshold is input by operating the first input unit. The operation time zone and the stationary time zone are specified using the obtained value as a predetermined threshold. The first input unit is, for example, the input unit 38.

According to the function 1, the user of the monitored person monitoring system MS (for example, the supervisor NS) can determine a predetermined threshold value. When the predetermined threshold value is small, the number of operating hours increases. When the predetermined threshold is large, the number of operation time periods is reduced. The user determines a value serving as a predetermined threshold in consideration of the body type of the monitored person Ob. For example, a person who is thin has a higher risk of bed slipping than a person who is fat, so detailed observation is necessary. Therefore, the threshold value of a thin person is smaller than that of a fat person (threshold value TH1 of a thin person is smaller than the threshold value TH2 of a fat person).

Function 2 will be explained. Referring to FIGS. 2 to 4, the operation time zone is a time zone in which the amount of motion measured sequentially exceeds a predetermined threshold in a predetermined time. Since this meaning is described in function 1, description thereof is omitted. In the monitored person monitoring system MS, when the second input unit and the second input unit are operated and a predetermined characteristic parameter relating to occurrence of bed slip is input for the monitored person Ob, based on the characteristic parameter And a first determination unit 34 for determining a predetermined threshold. The second input unit is, for example, the input unit 38.

According to the function 2, when the user of the monitored person monitoring system MS inputs the characteristic parameter of the monitored person Ob, a predetermined threshold is automatically determined based on the characteristic parameter. This will be specifically described. For example, the characteristic parameter is information indicating the body type of the monitored person Ob. The first determination unit 34 reduces the predetermined threshold value to be determined when the body shape of the monitored person Ob is thin, compared with the case where the body is fat. For example, the characteristic parameter is information indicating whether or not the monitored person Ob has symptoms of paralysis. When the monitored person Ob has a paralysis symptom, the first determination unit 34 reduces the predetermined threshold value to be determined as compared with a case where the monitored person Ob has no paralysis symptom. For example, the characteristic parameter is information indicating the location of the paralyzed person Ob. The first determination unit 34 reduces the predetermined threshold value to be determined in the case where the part of the monitored subject Ob is a predetermined part (for example, the buttocks) compared to the case where the part is not a predetermined part. In any case, when the risk of bed slip is high, the predetermined threshold value is set smaller than when the risk of bed slip is not high so that detailed observation is possible.

Function 3 will be described. Referring to FIG. 3 and FIG. 4, when the display control unit 37 (second display control unit) displays an image in the operation time zone, the display control unit 37 (second display control unit) When the image selected from the image is slid on the display unit 36 and the image in the still time period is displayed, the image selected from the images in the still time period in the shooting data D1 is slid on the display unit 36. Display.

The number of images selected by the display control unit 37 in each operation time zone is 1 or more, and is selected at a predetermined time interval (for example, every 10 seconds) in each operation time zone. The number of images selected by the display control unit 37 in each stationary time zone is 1 or more, and is selected at a predetermined time interval (for example, one minute interval) in each stationary time zone. The display control unit 37 causes the display unit 36 to slide-display the selected image in time series. More specifically, the display control unit 37 displays, in time series, images (frames) selected at predetermined time intervals from all images (all frames) in the operation time zone T2 during the operation time zone T2. Slide display is performed on the display unit 36. The display control unit 37 slide-displays images (frames) selected at predetermined time intervals from all the images (all frames) in the stationary time zone T1 in the stationary time zone T1 on the display unit 36 in time series. Let

According to the function 3, since the number of images to be reproduced in the operation time zone and the stationary time zone can be reduced, the supervisor NS can grasp the body movement in a state where the monitored person Ob is sleeping in a short time. Can do.

Function 4 will be described. With reference to FIG. 3 and FIG. 4, the monitored person monitoring system MS selects the image from the operation time zone and the stationary time zone by operating the third input unit and the third input unit. When the number of images is input, the display control unit 37 (second display control unit) displays an image in the operation time zone from among the images in the operation time zone in the shooting data D1. When the above-mentioned number of images are selected and slide-displayed on the display unit 36 in chronological order to display an image in the still time zone, the number of images is selected from among the images in the still time zone in the shooting data D1. Are displayed on the display unit 36 in a time series. The third input unit is, for example, the input unit 38.

According to the function 4, the user of the monitored person monitoring system MS can determine the number of images to be selected from the images in the operation time zone and the stationary time zone. The user determines the number of sheets in consideration of the body shape of the monitored person Ob. For example, a person who is thin has a higher risk of bed slipping than a person who is fat, so detailed observation is necessary. Therefore, a thin person increases the number of selected sheets as compared with a fat person.

It should be noted that a mode in which the third input unit is operated to input the number of images to be selected from images in the operation time period is also possible. In the case of this aspect, when the display control unit 37 (second display control unit) displays an image in the operation time zone, the display control unit 37 (second display control unit) selects the number of images from the images in the operation time zone in the shooting data D1. An image is selected and displayed on the display unit 36 in a time series. In this case, the number of images in the still time zone is preset in the display control unit 37 based on the number of images in the operating time zone (for example, the number of images in the still time zone is , Twice the number of images in the operating time zone).

In addition, a mode in which the third input unit is operated to input the number of images to be selected from images in a stationary time zone is also possible. In the case of this mode, when the display control unit 37 (second display control unit) displays an image in the stationary time zone, the display control unit 37 (second display control unit) selects the number of images from among the images in the stationary time zone in the shooting data D1. An image is selected and displayed on the display unit 36 in a time series. In this case, the number of images in the operating time zone is preset in the display control unit 37 based on the number of images in the stationary time zone (for example, the number of images in the operating time zone is , Half of the number of images in stationary time).

This will be specifically described. For example, the characteristic parameter is information indicating the body type of the monitored person Ob. The second determining unit 35 increases the number of sheets to be selected when the body shape of the monitored person Ob is thin compared to the case where the body is thick. For example, the characteristic parameter is information indicating whether or not the monitored person Ob has symptoms of paralysis. The second determination unit 35 increases the number of sheets to be selected when the monitored subject Ob has a paralysis symptom compared to a case where the monitored person Ob has no paralysis symptom. For example, the characteristic parameter is information indicating the location of the paralyzed person Ob. The 2nd determination part 35 increases the number of sheets to be selected when the part of the monitored subject Ob is a predetermined part as compared with a case where the part is not a predetermined part. In any case, when the risk of bed slip is high, the number of selected sheets is increased so that detailed observation can be performed as compared with the case where the risk of bed slip is not high.

(Summary of embodiment)
In the monitored person monitoring system according to the first aspect of the present embodiment, the imaging data obtained by imaging the state where the monitored person is sleeping for a predetermined time, and the amount of movement of the monitored person who is sleeping are described above. In a time zone in which the amount of movement exceeds a predetermined amount using the storage unit that stores in advance measurement data obtained by measuring the predetermined time in parallel with shooting, and the shooting data and the measurement data A specific unit that identifies a certain operating time zone and a stationary time zone in which the amount of movement is equal to or less than the predetermined amount on the time axis of the imaging data, and the monitored person sleeps in the stationary time zone. A determination unit that determines a sleeping posture that is a posture that is being displayed, and a first display control unit that causes the display unit to display the sleeping posture determined by the determination unit.

The operation time zone is, for example, a time zone during which the amount of motion measured sequentially exceeds a predetermined threshold during the predetermined time. The motion amount measured sequentially is, for example, a motion amount measured every predetermined time (for example, every second). The stationary time zone is a time zone other than the operating time zone, that is, a time zone in which the amount of motion measured sequentially in a predetermined time is equal to or less than a predetermined threshold.

The monitored person monitoring system according to the first aspect of the present embodiment determines a sleeping position in which the monitored person is sleeping in a stationary time period, and displays the determined sleeping position on the display unit. Thereby, the monitor can know the past sleeping posture of the monitored person. Therefore, when the monitoring person changes the sleeping posture of the person to be monitored next, it should be used as a reference for determining the timing to change to the next sleeping posture and determining which sleeping posture the next sleeping posture should be. Can do. The sleeping posture can be determined by performing predetermined image processing on the captured data, for example.

As described above, according to the monitored person monitoring system according to the first aspect of the present embodiment, management of the posture of the monitored person can be supported.

In the above configuration, the image display device further includes a second display control unit that causes the display unit to display an image of the monitored person indicated by the imaging data, and the second display control unit is specified by the specifying unit. An image in a stationary time zone is displayed on the display unit.

把握 It is important to know the correct sleeping posture in order to prevent the floor slip of the monitored person. According to the said structure, the 2nd display control part can display the image of the time slot | zone (stationary time slot | zone) where the to-be-monitored person is sleeping stably on a display part. Therefore, the monitoring person can grasp the monitoring person's sleeping posture more accurately.

In the above configuration, the second display control unit causes the display unit to display an image in the operation time zone specified by the specifying unit, and displays a reproduction speed of the image in the operation time zone in the stationary time zone. Faster than the playback speed of images.

As described above, when the monitoring person grasps the posture of the monitoring person sleeping, it is not necessary to view an image of the time period (operation time period) in which the monitoring person is moving. According to this configuration, it is possible to shorten the reproduction time of an image whose necessity for viewing is low by increasing the reproduction speed in the operation time zone.

In the above configuration, the operation time zone is a time zone in which the amount of motion sequentially measured in the predetermined time exceeds a predetermined threshold, and the monitored person monitoring system further includes a first input unit. The specifying unit specifies the operation time zone and the stationary time zone based on the predetermined threshold value input by operating the first input unit.

According to this configuration, a user (for example, a supervisor) of the monitored person monitoring system can determine a predetermined threshold value. When the predetermined threshold value is small, the number of operating hours increases. When the predetermined threshold is large, the number of operation time periods is reduced. The user determines a value to be a predetermined threshold in consideration of the body shape of the monitored person. For example, a person who is thin has a higher risk of bed slipping than a person who is fat, so detailed observation is necessary. Therefore, a predetermined threshold is made smaller for a thin person than for a fat person.

In the above configuration, the operation time zone is a time zone in which the amount of movement sequentially measured in the predetermined time exceeds a predetermined threshold, and the monitored person monitoring system includes a second input unit, A first determination unit configured to determine the predetermined threshold based on a predetermined characteristic parameter related to the monitored person input by operating the second input unit;

According to this configuration, when the user of the monitored person monitoring system inputs the characteristic parameter of the monitored person, the predetermined threshold is automatically determined based on the characteristic parameter. This will be specifically described. For example, the characteristic parameter is information indicating the body shape of the monitored person. A 1st determination part makes the predetermined | prescribed threshold value to determine small when compared with the case where it is fat when the to-be-monitored person's body shape is thin. For example, the characteristic parameter is information indicating whether the monitored person has symptoms of paralysis. A 1st determination part makes the predetermined | prescribed threshold value to determine small when the to-be-monitored person has the symptom of paralysis compared with the case where it does not have the symptom of paralysis. For example, the characteristic parameter is information indicating the paralysis location of the monitored person. A 1st determination part makes the predetermined | prescribed threshold value to determine small compared with the case where the location of the to-be-monitored person's paralysis is a predetermined location (for example, a buttocks) compared with the case where it is not a predetermined location. In any case, when the risk of bed slip is high, the predetermined threshold value is set smaller than when the risk of bed slip is not high so that detailed observation is possible.

In the above configuration, the characteristic parameter is information indicating a bedsore risk including at least one of the body shape of the monitored person, whether or not the patient has a paralysis symptom, and the location of the paralysis, The determination unit of 1 determines the predetermined threshold according to the floor slip risk. The first determination unit that determines the predetermined threshold according to the bed slip risk reduces the predetermined threshold when the floor slip risk is high compared to when the floor slip risk is low. For example, if the first determining unit is thin, has paralysis symptoms, and the part of the paralysis is a place where the risk of bed slippage is high (for example, the buttocks), the predetermined threshold value is minimized and is fat. When there is no symptom of paralysis, the predetermined threshold is set to the highest. According to this configuration, since the predetermined threshold is determined according to the specific risk of bed slip and personal risk, it can be set to a predetermined threshold that accurately reflects the risk of bed slip of the monitored person. (When the risk of bedsores is high, the predetermined threshold is reduced, and when the risk of bedsore is low, the predetermined threshold is increased).

In the above configuration, when the second display control unit displays an image in the operation time zone, an image selected from images in the operation time zone in the shooting data is displayed on the display unit. When the slide display is performed and an image in the still time period is displayed, an image selected from the images in the still time period in the shooting data is displayed on the display unit.

The number of images selected by the display control unit in each operation time zone is 1 or more, and is selected at a predetermined time interval (for example, every 10 seconds) in each operation time zone. The number of images selected by the display control unit in each still time zone is 1 or more, and selection is made at predetermined time intervals (for example, 1 minute intervals) in each still time zone. According to this configuration, since the number of images to be reproduced during the operation time zone and the stationary time zone can be reduced, the monitor can grasp the body movement in the state where the monitored person is sleeping in a short time. .

In the above configuration, the image display device further includes a third input unit for inputting the number of images to be selected from images in the operation time period and / or the still time period, and the second display control unit When displaying an image in a time zone, the third input unit is operated to select and display the number of images input from the images in the operation time zone, and the image in the stationary time zone is displayed. When displaying the image, the third input unit is operated from the images in the still time zone, and the input number of images is selected and displayed. When another expression is used, in the above configuration, the image processing apparatus further includes a third input unit, and the third input unit is operated to select an image to be selected from the images in the operation time zone and the stationary time zone. When the number of images is input, the second display control unit, in the second display control, at the time of the operation time, the number of the images is selected from the images in the operation time of the shooting data. Select an image and slide it on the display unit. During the stationary time period, select the number of images from the images in the stationary time period in the shooting data and slide display on the display unit. Let

According to this configuration, the user of the monitored person monitoring system can determine the number of images to be selected from the images in the operation time zone and / or the stationary time zone. The user determines the number of sheets in consideration of the body shape of the monitored person. For example, a person who is thin has a higher risk of bed slipping than a person who is fat, so detailed observation is necessary. Therefore, a thin person increases the number of selected sheets as compared with a fat person.

In the above configuration, a fourth input unit for inputting a predetermined characteristic parameter (predetermined characteristic parameter regarding occurrence of bed slip) relating to the monitored person, and the characteristic parameter input by operating the fourth input unit And a second determination unit that determines the number of images to be selected from images in the operation time period and the still time period.

According to this configuration, when the user of the monitored person monitoring system inputs the feature parameter of the monitored person, the number of images to be selected is automatically determined based on the feature parameter. This will be specifically described. For example, the characteristic parameter is information indicating the body shape of the monitored person. The second determination unit increases the number of sheets to be selected when the body shape of the monitored person is thin, compared to when the person is fat. For example, the characteristic parameter is information indicating whether the monitored person has symptoms of paralysis. A 2nd determination part increases the number of sheets to select, when a to-be-monitored person has the symptom of paralysis compared with the case where he does not have the symptom of paralysis. For example, the characteristic parameter is information indicating the paralysis location of the monitored person. The second determination unit increases the number of sheets to be selected when the part to be monitored of paralysis is a predetermined part as compared with a case where the part is not a predetermined part. In any case, when the risk of bed slip is high, the number of selected sheets is increased so that detailed observation can be performed as compared with the case where the risk of bed slip is not high.

In the above configuration, the characteristic parameter is information indicating a bedsore risk including at least one of the body shape of the monitored person, whether or not the patient has a paralysis symptom, and the location of the paralysis, The determination unit of 2 increases the number of sheets to be determined when the floor slip risk is high compared to when it is low. For example, if the second determination unit is thin, has paralysis symptoms, and the part of the paralysis is a place where the risk of bed slippage is high (for example, the buttocks), the number to be determined is the largest and fat. If there are no symptoms of paralysis, the number to be determined is minimized.

According to this configuration, the number of sheets is determined according to the specific risk of bed slip and the individual risk, so that the floor slip risk of the monitored person can be accurately reflected in the number of sheets (risk of floor slip). If the number is high, the number of sheets increases. If the risk of bed slipping is low, the number of sheets decreases.)
