Abstract

PROBLEM TO BE SOLVED: To check out dementia by a method other than a method of making judgments based on answers to questions.SOLUTION: A system for checking out dementia in an early stage comprises a terminal 1 disposed in a dwelling house, and monitoring means 3 connected via network 2. The terminal 1 includes switching means 4a operated in accordance with daily routine actions. When a switching operation has been carried out, the terminal 1 notifies the monitoring means 3 of the fact. The monitoring means 3 finds out operation different from a daily operation tendency based on the tendency of the daily operation status of the switching means 4a from the terminal 1 to check out the dementia. In this way, dementia can be checked out by a method other than a method of making judgments based on answers to questions.

Description

  The present invention relates to a system for determining an early stage of dementia intended for a person at home.

As a system for determining dementia, there is a dementia diagnosis system shown in Patent Document 1. This support system has a server for generating questions and correct answers, and a patient side device for outputting questions and inputting answers to patients, both of which send and receive information via the Internet, LAN, etc. Is possible.
In this system, the patient's individual dementia level is simply diagnosed by asking the patient questions such as the patient's individual schedule and attributes, weather and news that change daily, and determining the answer. That's it.

JP 2007-282929 A

However, in the above method, dementia is simply diagnosed by determining an answer to the question. Therefore, even if you are not demented, you may be diagnosed with dementia if you do not answer the question well. For example, there are impatience and tension that a question must not be answered, poor mechanical operation, slow motion, or no interest in the question.
On the other hand, there is a problem that dementia is not diagnosed if the correct answer is given to the question in dementia. For example, it is a case of “mottled dementia” that disappears only when asked and can be answered by chance.

  Then, the subject of this invention is making it possible to identify dementia by methods other than the method of determining the answer with respect to a question.

  In order to solve the above-described problems, the present invention comprises a terminal arranged at home and a monitoring means connected via a network, and the terminal is operated in accordance with daily determined actions And a communication means for informing the monitoring means that the switch means has been operated. The monitoring means includes: a receiving means for receiving notification from the communication means of the terminal; and a switching means from the terminal received by the receiving means. A configuration equipped with a diagnostic means for determining dementia based on the tendency of daily operating conditions was adopted.

  By adopting the above configuration, it is decided to operate the switch at the time of getting up, for example, as a routine action determined daily. Then, when the switch operation is performed, the terminal notifies the monitoring means that the switch operation has been performed. The monitoring means determines dementia based on the tendency of the daily operation status of the switch means. For example, dementia can be identified by finding an operation that is different from the daily operation tendency, such as frequently forgetting the switch operation or performing the switch operation many times a day. In this way, since the switch operation is performed on a daily basis, the operation can be prevented from being impatient or nervous. Further, by repeating the switch operation on a daily basis, it is possible to become familiar with the operation at the pace of the observer. Therefore, even if the operation is not good or the operation is slow, it can be mastered. Furthermore, since it is a routine operation, it does not require interest in questions. Moreover, even in the case of “mottled dementia” where the symptoms of dementia are uneven, dementia can be determined by performing daily operations.

  At this time, a configuration is adopted in which the diagnosis means calculates the tendency of the daily operation situation based on statistics from the life rhythm that accumulates the data of the daily action periodically repeated based on the switch means. Can do.

  By adopting such a configuration, it is possible to grasp dementia by quantitatively grasping the tendency of life rhythm by taking statistics.

  At this time, the terminal can be configured by a sensor unit including an operation unit including a switch unit, a human sensor unit that detects the location of the person to be observed, and a terminal body unit.

  By adopting such a configuration, by configuring the switch means as the operation unit, it can be arranged in a place where it can be easily operated if it is separated from the terminal body unit. In addition, by providing the human sensor unit, the location of the person to be observed can be known and the activity status can be understood, so the accuracy in verifying the life rhythm can be improved.

  The terminal main body stores a life rhythm storage unit that stores the operation of the switch means of the sensor unit and the detection signal of the human sensor unit together with time data, and a notification mail generation that transmits the data stored in the life rhythm storage unit by mail The structure provided with the part can be adopted.

  By adopting such a configuration, the switch operation of the sensor unit and the detection data of the human sensor unit are stored in the life rhythm storage unit, so that the data can be collected and transmitted using mail at an arbitrary time. Therefore, each time the switch is operated, the amount of communication can be reduced rather than sending mail.

  At this time, by adopting a configuration in which the switch means is associated with daily actions such as “getting up” and “sleeping”, it is possible to determine the daily action determined.

  Further, at this time, it is possible to adopt a configuration in which the occurrence of abnormality is watched from the above life rhythm.

  By adopting such a configuration, the person to be observed can be watched by detecting and notifying an abnormal operation from the tendency of the daily operation status of the switch means of the terminal.

  By configuring the present invention as described above, dementia can be determined.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
As shown in FIG. 1, the dementia initial assessment system of the present invention comprises a terminal 1 arranged at home and a monitoring means 3 connected via a network 2, and the monitoring means 3 is provided here in a call center. It has been.

As shown in FIG. 2, the terminal 1 includes a monitoring sensor unit 4 and a monitoring device base unit 5.
The watching sensor unit 4 includes a switch operation unit 4a and a human sensor unit 4b.
The switch operation unit 4a is provided with a push button switch 6 in a case, and is connected to the monitoring device base unit 5 by a USB interface.
The push button switch 6 is a push switch that is turned on only while being pressed, and in this embodiment, two switches of the first button 6a and the second button 6b are used.
This is limited to two in order to simplify the operation of the person to be observed, and it is also possible to increase the accuracy of identifying dementia using two or more switches.
The first button 6a and the second button 6b are assigned and associated with daily actions performed by the subject. For example, the buttons are suitable for the observer's preference from daily activities such as “getting up”, “meal”, “walking”, “bathing”, “sleeping”, etc. Choose what.
In this embodiment, the human sensor unit 4b uses a Doppler sensor using a microwave. The sensor 4b is connected to the monitoring device base unit 5 with a USB cable, and the sensor 4b is arranged in a living room to detect the location of the observer.
In addition to the Doppler sensor, a passive sensor using far infrared rays or the like can be used as the human sensor unit 4b.

The watch unit base unit 5 includes an out / return button 5a and an emergency button 5b at the top of a slightly larger lunch box type case. The inside includes a microprocessor, a memory, an I / O interface, a communication interface, a calendar IC, and the like, and can be represented by functional blocks as shown in FIG.
That is, the master unit 5 includes a home / absence determination unit 7, a life rhythm storage unit 8, a notification mail generation unit 9, and a communication unit 10.

The home / absence determination unit 7 determines that the out / return button 5a has been pressed and stores the time.
Specifically, the go / go home button 5a is an illuminated alternate switch that is turned on and off each time it is pressed. If the state before pressing is “at home”, it changes to “absent” after pressing and is pressed. If the previous state is “absent”, after pressing, it changes to “at home”. Therefore, the home / absence determination unit 7 stores this change and turns on the built-in lamp of the switch 5a. For example, the lamp is turned on when absent, and the lamp is turned off when at home. By displaying in this way, forgetting to press is prevented.
Then, the inversion information of “at home” and “absence” of the out / return button 5 a and the data of the inversion time are sent to the notification mail generation unit 9 once a day at a preset time.

The life rhythm storage unit 8 stores the life rhythm of the person to be observed based on the pressing signal of the push button 6 input from the switch operation unit 4a of the watching sensor unit 4 and the detection signal input from the human sensor unit 4b.
Specifically, the time when the push signal of the push button 6 is detected (the time when the push button 6 is pressed) and the detection time of the human sensor unit 4b are stored for one day in time series.
At this time, the recording of the human sensor unit 4b divides one hour into four every 15 minutes, and stores in which time zone of the four divisions the detected time of the received human sensor unit 4b is detected.
For example, 1 hour is divided into four every 15 minutes as follows.
1. 1st time zone every hour 0 minutes 0 seconds to 14 minutes 59 seconds 2. Second hour hour 15 minutes 0 seconds to 29 minutes 59 seconds 3rd time zone every hour 30 minutes 0 seconds-44 minutes 59 seconds 4. The fourth time zone is 45 minutes 0 seconds to 59 minutes 59 seconds per hour. At this time, when the human sensor unit 4b detects a plurality of times in the same time zone, the number of times is stored together.
The life rhythm information including the time when the push button 6 is detected and the detection time of the human sensor 4b is sent to the notification mail generator 9 once a day at a preset time. . That is, information from the previous transmission time stored in the life rhythm storage unit to the present is sent out.

The notification mail generation unit 9 has a mailer function, and when receiving home and absence time data sent from the home / absence determination unit 7 and life rhythm data sent from the life rhythm storage unit 8, the data content is received. Generate a notification email message to be sent to the call center.
The message is, for example,
1. Describes the pressing time of the “first button 6a” in time series.
2. Describes the pressing time of the “second button 6b” in time series.
3. 3. The detection time of “human sensor unit 4b” is described for each time zone. The number of detections of “human sensor 4b” is described for each time zone.
5. Describes the pressing time of the “go / go home button 5a” and the inverted data of the button 5a.
It is a thing of contents.
The created mail is given an e-mail address for identifying the terminal (observer) 1, and, for example, inputs the address of the call center and transmits it via the communication unit 10.

The communication unit 10 includes an analog modem 10a and a LAN connection interface, and connects a telephone line or a PPPoe connection Internet line according to a network to be used. Then, the communication unit 10 determines the connected line. Then, once a day, when a predetermined time is reached, a communication protocol corresponding to the determination result is started, and mail is transmitted by communicating with the monitoring means 3 in the call center.
As described above, the transmission is performed once a day, thereby reducing the traffic and reducing the load on the monitoring means 3 so that a large number of persons can be identified.

The call center includes a server computer as the monitoring means 3. This server computer has a monitoring function with a mail server, and a plurality of monitoring computers 11 are connected thereto.
The mail server is provided as a receiving means for receiving mail from the terminal 1. The received mail is sent to the monitoring computer 11 and sent to the monitoring computer 11 at the same time. By distributing mail to the monitor computer 11 in this way, checking by human eyes can be received.
The watch monitoring function has a processing function (program) for specifying the person to be observed (transmission terminal) from the mail transmission address and a processing function (program) for acquiring the contents described in the mail. Here, the description is easy to obtain as data because it is a text data format of the fixed phrase as shown above.
And the diagnostic means (program) which finds dementia based on the tendency of the daily operation state of a button from the acquired data is provided.

Reference numeral 12 in FIG. 2 is for receiving a signal from a wireless door switch (not shown) by an antenna.
The emergency call button 5b in FIG. 2 is provided for directly reporting to the call center that an emergency has occurred. In order to use it, a telephone line is connected to the monitoring device base unit 5 in advance. In this way, when the emergency notification button 5b is pressed, the modem 10a dials the call center to notify a predetermined message notifying the emergency situation. By the way, the call center that received the report calls for confirmation, and as a result, if it is determined that an emergency is required, the call center 119 is notified.

This configuration is configured as described above, and the terminal 1 assigns an e-mail address in advance, stores the e-mail address of the call center, and arranges it at the home of the subject who is the user who determines dementia To do. Then, the daily behavior that motivates the operation of the push button 6 with the person to be observed is determined.
To be specific, the person to be observed is a daily routine that repeats periodically such as “getting up”, “meal”, “cleaning”, “walking”, “shopping”, “bathing”, “sleeping”, etc. Choose an action that motivates the operation of push button 6. In this way, the operation of the push button 6 is not forgotten by motivation.
Here, “wake up” and “sleeping” are selected. That is, when waking up in the morning, the “first button 6a” is pressed. Also, the “second button 6b” is pressed when going to bed at night.
For example, the terminal 1 is arranged in a living room such as a living room where a person spends a long time in the day so that the terminal 1 can be watched simultaneously with the diagnosis of dementia. Then, for easy operation, the monitoring device master unit 5 and the monitoring sensor unit 4 of the terminal 1 are separated, the human sensor unit 4b of the separated monitoring sensor unit 4 is disposed in the living room, and the switch operation unit 4a is arranged. Place them on a living table or the like and connect them to the parent device unit 5 using a USB cable. In addition, an internet line is connected to the monitoring device base unit 5.
Now that the preparation is complete, the observer presses the “first button 6a” when waking up in the morning, and presses the “second button 6b” when sleeping at night.
Then, an electronic mail with the following contents is sent to the control center once a day at a predetermined time.
1. Pressing time of the “first button 6a”,
2. Press time of “second button 6b”,
3. 3. Time zone detected by the “human sensor unit 4b” 4. Number of times of detection of “human sensor 4b” for each time zone Pressing time of “go / go home button 5a” and inverted data of the button 5a

In the call center, when the mail is received, the sender terminal (observer) is specified from the mail address of the sender.
When the observer can be identified, the mail data is sorted and stored for each item. Since the accumulated data reflects the rhythm of life, based on this information, the processing program of the diagnosis function of the server computer 3 provides statistics on the pressing state of the push button 6 and the detection state of the human sensor unit 4b. create. Moreover, a statistical table and a total vote are prepared from the statistics.
When the statistics are created in this way, for example, as shown in FIG. 4, when the time is displayed on the horizontal axis and the number of times the push button 6 is pressed is displayed on the vertical axis, the dispersion state varies depending on the individual, but the wake-up time and the bedtime are displayed. The number of times the time is pressed should exhibit a normal distribution reflecting the tendency of the life rhythm of the person to be observed as shown in FIG.

  Here, if the push button 6 is frequently forgotten or the same push button 6 is pushed many times a day, a deviation 13 deviating from the distribution is generated. Therefore, when the deviation 13 reaches a level deviating from a common sense of forgetfulness, it is determined as an initial dementia.

  Therefore, for example, when the server computer 3 detects that there is no operation of the first button 6a within a hour from the average wake-up time, c times within b days, the caution information is displayed on the screen of the monitor computer 11. By executing the appropriate processing, it is possible to determine the initial symptoms at the call center.

  When the initial symptoms are determined in this way, as shown in FIG. 5, a one-month statistical table is distributed to the “municipal government office”, the “dementia initial concentration support team”, and the like. And by encouraging visits based on the data, it can contribute to early detection of dementia.

  Thus, by taking statistics, it is possible to quantitatively grasp the life rhythm and determine dementia from the tendency. Since the operation performed at that time is performed on a daily basis, the operation does not involve impatience or tension. Further, since the operation is repeated on a daily basis, the operation can become familiar with the operation at the pace of the observer. Therefore, it can be overcome even if the operation is poor or the operation is slow. In addition, since it is a daily operation, you will not lose interest in the questions. In addition, even in the case of “mottled dementia” where the symptoms of dementia are uneven, the operation is performed every day, so dementia can be determined.

At this time, by using the human sensor 4b, it is possible to improve the accuracy of determining dementia.
That is, in this embodiment, the human sensor unit 4b is installed in a room where the switch operation unit 4a is operated. Therefore, the time zone in which the human sensor unit 4b detects the person to be observed should overlap the distribution of FIG. Therefore, when the human sensor 4b detects the person to be observed but the push button 6 is not pressed, the push button 6 is not simply forgotten, and the push button 6 is not recognized. Probably high.
Therefore, by calculating the statistical result of the data accumulated by pressing the human sensor unit 4b and the push button 6 and displaying it on the monitor screen at the same time as the previous determination result, it is possible to improve the determination accuracy.

In Example 1, it will be described that the system of the present application can also watch for safety in addition to determining the dementia described in the embodiment.
That is, as described above, at the call center, for example, after detecting “no operation of the first button 6a within a hour from the average wake-up time c times within b days”, the dementia is identified. Yes. Therefore, when determining the dementia of embodiment, it alert | reports after abnormality arises in multiple times. This is displayed on the monitor computer 11 as monitoring information when an abnormality occurs each time, and is monitored by confirming safety from the call center by telephone or the like.
Further, if the human sensor 4b does not detect a person's movement at the time of getting up, it may be a fall, so the safety is confirmed from the call center by telephone or the like. Furthermore, if the person is not informed by e-mail with the “going out / going home button 5a” but the human sensor 4b does not detect a person's movement for a long time, it is possible that the person has fallen down. Confirm the safety by such as.
As described above, when an abnormality occurs, the information is displayed on the monitor computer 11 as monitoring information, and the safety can be confirmed by telephone from a call center.
