Description

The present invention relates to an activity status management device.

A childcare diary is very useful for parents with babies. For example, by recording daily events that occur in daily life such as sleep, awakening, body movement, breastfeeding, milk, and excretion in the childcare diary, whether the child is sleeping well or is moving well, milk as usual. You can go back and check the past situation to see if you are drinking. Furthermore, it is possible to grasp the state of health and growth of the child. In addition, some parents keep their childcare diary for a long time as a memorial to their growth. The contents of recording such a childcare diary can be roughly divided into two types. For example, there are the result of observing the state of the child and the result of performing on the child. As a result of observing the state of the child, there are the state of sleep and body movement. The results of the feeding on the offspring include the time of breastfeeding, the amount of milk given, and excretion. Then, the childcare diary needs to be recorded by hand while the parent confirms the child's condition near the child.
Parents should be able to concentrate on childcare, but they must also do household chores. Therefore, they may temporarily move away from the child.
On the other hand, there is a biological monitoring device for the purpose of watching over an infant (see, for example, Patent Document 1).

Japanese Patent No. 5495952

However, the above-mentioned biological monitoring device detects whether or not the baby is in an apnea state. Therefore, it does not suit the purpose of parents who want to understand the state of daily life. In addition, in order to record a childcare diary, it is necessary to write in the childcare diary by hand, which is troublesome for parents. Furthermore, the parent needs to be in the vicinity of the child and always look at the child in order to grasp the time when the child went to bed, the time when the child woke up, and whether the body movement was active or calm. This makes it difficult to do household chores that must be done away from the child. Furthermore, if you move away from the child, not only will you not be able to grasp the child's condition, but you may also be worried about the child's condition, and household chores may not progress.

The present invention has been made in view of such circumstances, and an object thereof is an activity capable of grasping the state of a subject to be watched without directly visually recognizing it and easily recording an event performed on the subject. The purpose is to provide a situation management device.

In order to solve the above problems, the present invention proposes the following means.
(1) The activity status management device (for example, a combination of the child-rearing support device 40 and the terminal device 30, any of the child-rearing support device 40 and the terminal device 30) according to the present invention is a person to be measured (for example, a child 15). ), A biological information acquisition unit (for example, a biological sensor 10 or a receiving unit 41) that acquires biological information representing the biological activity of the above, and an output unit that outputs activity information indicating the activity status of the person to be measured according to the biological information. (For example, display unit 341 or transmission unit 47), an input unit (for example, input unit 342 or reception unit 41) for inputting event information representing an event performed on the person to be measured, and the biometric information. It has a storage unit (for example, an activity history storage unit 33 or an activity history storage unit 43) that stores the event information.

According to the activity status management device of the present invention, while outputting the activity information indicating the activity status of the person to be measured according to the acquired biometric information, the input of the event information is accepted and the biometric information and the event information are stored in the storage unit. Can be memorized in. As a result, it is possible to grasp the activity information of the person to be measured corresponding to the biological information based on the output from the output unit, so that it is possible to increase the number of situations in which the person to be measured does not have to be directly visually observed. .. Furthermore, since the acquired biometric information is stored together with the event information, it is not necessary to input information related to the biometric information among various information indicating the state of the person to be measured, and it is sufficient to input the event information. Therefore, it is possible to save the trouble of inputting and easily memorize the information.

(2) In the activity status management device according to (1) above, the activity information may be output in a mode corresponding to the change in the activity status of the person to be measured.

In this case, since the activity information is output in a mode corresponding to the change in the activity status of the person to be measured, the state of the change in the activity status can be easily grasped by using the change in the mode as a clue.

(3) In the activity status management device according to (1) or (2) above, the activity information may be at least one of the body movement, respiration, heartbeat, sleep, and arousal of the subject. Good.

It further has an extraction unit (for example, an activity estimation unit 44) that acquires biological data related to the event information as an extraction result, and the output unit outputs the activity information according to the extraction result. You may.

In this case, since the biometric information related to the event information can be output, the relevant biometric information can be obtained only by inputting the event information.

(5) In the activity status management device according to (4) above, the timing of the event predicted to occur in the future based on the extraction result, the event information related to the extraction result, and the history of the biological information. May have a generation unit (for example, a schedule generation unit 45) that generates a schedule based on the timing at which the event occurs.

In this case, the generation unit can generate a schedule based on the prediction result of predicting the timing of an event that will occur in the future. As a result, it is possible to grasp in advance the phenomenon to be performed and the timing thereof for the person to be measured and prepare for it.

(6) In the activity status management device according to any one of (1) to (5) above, the storage unit may store the biological information or the activity information and the event information.

Hereinafter, a childcare support system, which is an example of the case where the activity status management device according to the embodiment of the present invention is applied to childcare, will be described with reference to the drawings.
FIG. 1 is a conceptual diagram showing the configuration of a childcare support system.
As shown in FIG. 1, the childcare support system 1 includes a biological sensor 10, a communication device 20, and a terminal device 30.
The biosensor 10 is installed between, for example, the mattress 16 and the floor of a bed (not shown), and detects the biometric information of the child 15 who is in the mattress 16. For example, the biological sensor 10 generates an electric signal corresponding to a vibration generated due to a biological activity such as a body movement of a child 15. The communication device 20 is connected to the biosensor 10 and wirelessly transmits an electric signal (detection result) generated by the biosensor 10 to the terminal device 30 as biometric information.

The terminal device 30 is a portable terminal device such as a smartphone or tablet, and outputs activity information indicating the activity status of the child 15 according to the biological information to the touch panel based on the biological information transmitted from the communication device 20. .. In this case, the terminal device 30 outputs the activity information in a manner corresponding to the change in the activity status of the child. An image of the child 15 is displayed on the touch panel 34 (see FIG. 5), and activity information and an input button are displayed in the vicinity of the image of the child 15. The activity information displayed on the touch panel 34 includes body movement, respiration, heartbeat, sleep, awakening, and the like, and is displayed in a different graphic for each item. For example, when outputting activity information related to a heartbeat, the terminal device 30 blinks a heart mark according to a rhythm corresponding to the heart rate, vibrates due to vibration, or outputs a heartbeat sound from a speaker. Further, the terminal device 30 can also change the display size of the heart mark according to the strength of the heartbeat based on the biological information. In this way, it is possible to express not only whether or not there is a beat, but also its strength. This allows parents to keep track of what their child's heart rate is, even if they are doing household chores away from where their child is in bed (eg, kitchen or balcony). Not only that, but also its strength can be grasped by the display content, vibration, and voice of the touch panel 34.

Further, the input button displayed on the touch panel 34 receives the event information representing the event performed regarding the childcare of the child 15 by the operation input of the parent. As this event information, for example, event information such as breastfeeding, milk, and diaper change accompanying excretion is input. In this case, since the activity information is displayed on the touch panel 34, the event information can be input while looking at the displayed activity information.

In general, newborns will be able to turn over after 6 months of age. When the child turns over, the child 15 changes the bed position by turning over, for example, on the mattress 16. If the position on the mattress 16 on which the child 15 is located changes, there is a possibility of going out from the mattress 16. Even in such a case, since the childcare support system 1 according to the present embodiment can also grasp the amount of body movement of the child 15, the number of times the child turns over even if the parent is away from the child. You can grasp the number. This allows the parent to use the amount of body movement as a clue to determine if the child 15 has moved out of the mattress 16.

Infants, especially newborns, also have an immature respiratory center, which can lead to irregular respiratory rhythms even under normal conditions. For this reason, the parent is worried that the child 15 is breathing normally even when the child 15 is sleeping quietly, and repeatedly returns to the vicinity of the child to check the sleeping breath, so that the child 15 can see the eyes. It may not be possible to separate and act in a planned manner. Even in such a case, since the childcare support system 1 according to the present embodiment can display the breathing state of the child 15, the parent can grasp the breathing of the child 15 even if the parent is away from the child 15. can do. Further, since the childcare support system 1 can display the heartbeat state of the child 15, the parent can grasp the heartbeat state of the child 15 together with the breathing of the child 15, and pulsates with the breathing of the child 15. You can feel the feeling of peace of mind.

Newborn babies have no distinction between day and night, and repeat their lives of sleeping and waking up and drinking breast milk and milk day and night. Generally, it is said that the rhythm of life will be set when a few months have passed since birth, but depending on the family environment, the rhythm of life may be taken by waiting for the father to return home at a fixed time. Is often not set. It is also said that if the rhythm of life is not adjusted, it may cause developmental disorders. Even in such a case, the childcare support system 1 can refer to the past event information as needed after inputting the event information. As a result, the parent can grasp and improve the life rhythm of the child 15 by using the timing when the event is held as a clue.

The childcare support system 1 can also display characters to notify the abnormality and output an alarm sound in the event of an abnormality such as when the breathing of the child 15 cannot be detected.

Next, FIG. 2 is a system configuration diagram showing the configuration of the childcare support system 1.
In FIG. 1, the communication device 20 and the terminal device 30 connected to the biosensor 10 are shown, but as shown in the example of FIG. 2, the communication device 20 and the terminal device 30 support childcare via the network 50. It can also communicate with the device 40. The biosensor 10 outputs an electric signal corresponding to the vibration generated from the person to be measured who is on the mattress 16 or the like. As the biosensor 10, for example, a film sensor can be used. When raising a child, the place where the child is laid down is not limited to the bed, but in consideration of the time of day, the degree of sunlight, ventilation, etc., a simple futon may be laid in the living room or Japanese-style room. Therefore, it is preferable that the biosensor 10 can be easily installed even when the location is changed. Therefore, by using a film sensor as the biological sensor 10, it can be easily carried and installed. Further, since the film sensor is thin, even if it is installed, it is possible to reduce the discomfort given to the child who is on the mattress 16 or the futon. Further, the biosensor 10 is a non-wearable type sensor that does not need to be worn and worn by the person to be measured. Therefore, it is suitable for newborn babies with sensitive skin because it is possible to acquire biological information.
The communication device 20 is connected to the biosensor 10, and is connected to the terminal device 30 for short-range wireless communication (for example, Wi-Fi (Wi-Filess Fidelity), NFC (Near Field Communication), Bluetooth (registered trademark), infrared communication, etc. ) Is connected. Further, the communication device 20 is connected to the childcare support device 40 via the network 50. The terminal device 30 is connected to the communication device 20 and is connected to the childcare support device 40 via the network 50.

Here, the communication device 20 may be connected via a Wi-Fi router when connecting to the network 50. This Wi-Fi router is installed at home or a facility (hospital, public institution, etc.), for example. When connecting to the Wi-Fi router, the password may be manually input directly if the communication device 20 has an input unit, a display unit, or the like, but the terminal device 30 may be used. When using the terminal device 30, the user selects a Wi-Fi access point in advance from the terminal device 30 to connect to Wi-Fi, inputs a password, and connects the terminal device 30 and the Wi-Fi router. After that, when the user holds the terminal device 30 over the communication device 20, the NFC transmits Wi-Fi connection information such as a password from the terminal device 30 to the communication device 20. The communication device 20 connects to the Wi-Fi router using this Wi-Fi connection information. When at least a part of the services provided by the childcare support device 40 can be used by charging, the communication device 20 is a contactless IC card (for example, Suica (registered trademark), PASMO (registered trademark)). Etc.) may be touched to perform electronic payment processing with the childcare support device 40 (or billing server) by the NFC communication function.

FIG. 3 is a functional block diagram showing the functions of the terminal device 30.
The terminal device 30 includes a receiving unit 31, a control unit 32, an activity history storage unit 33, a touch panel 34, a speaker 35, a camera 36, and a transmitting unit 37.
The receiving unit 31 receives various data transmitted from the communication device 20 or the childcare support device 40. The control unit 32 controls each unit in the terminal device 30. The activity history storage unit 33 stores event information input from the touch panel 34, activity information received from the reception unit 31, and the like. The touch panel 34 has a display unit 341 and an input unit 342, and displays various information on the screen and inputs various information in response to a touch operation. The speaker 35 outputs audio. The camera 36 has an imaging function, and for example, takes a picture of a child 15 who is a subject to be measured. The transmission unit 37 transmits various information such as event information input from the touch panel 34 to the childcare support device 40.

FIG. 4 is a functional block diagram showing the functions of the childcare support device 40.
The childcare support device 40 includes a receiving unit 41, an activity history generation unit 42, an activity history storage unit 43, an activity estimation unit 44, a schedule generation unit 45, a control unit 46, and a transmission unit 47. The receiving unit 41 receives the information transmitted from the communication device 20 or the terminal device 30. For example, the receiving unit 41 receives the biological information representing the biological activity of the person to be measured, which is transmitted from the communication device 20.
The activity history generation unit 42 generates activity information indicating the activity status of the person to be measured (child 15) according to the biological information. The activity history generation unit 42 extracts, for example, the amplitude of an electric signal represented by biological information or a specific frequency component included in the electric signal, and outputs activity information based on the extracted amplitude and the specific frequency component. .. Activity information includes body movement, breathing, heartbeat, sleep, arousal, and the like.

It is considered that the body movement has a large vibration as compared with the respiration and the heartbeat, and the amplitude of the electric signal corresponding to the vibration is large. Utilizing this characteristic, the activity history generation unit 42 determines, for example, that the body is in a state of having body movement when the amplitude of the electric signal represented by the biological information is equal to or more than a predetermined body movement threshold value.
In general, the respiratory rate of a normal newborn baby is around 40 times per minute. The activity history generation unit 42 passes, for example, a frequency component of 0.5 to 1.0 Hz (hertz) corresponding to this respiratory rate (about 30 to 60 times per minute) through an electric signal represented by biological information. By passing through, the frequency component of this band is extracted. The activity history generation unit 42 determines the state of respiration (inhalation, exhalation, its intensity) based on the value of the signal of the extracted frequency component.
In addition, the newborn's heart rate is around 140 beats per minute. For example, the activity history generation unit 42 extracts a frequency component in a range corresponding to the heartbeat from an electric signal represented by biological information, and based on the value of the extracted signal, determines the state of the heartbeat (contraction, relaxation, its strength). judge.
The activity history storage unit 43 stores biological information, activity information, and event information in association with each other.

Based on the biometric information and the event information, the activity estimation unit 44 acquires the biometric data related to the event information among the biometric data corresponding to the measurement items in the biometric information as the extraction result. The activity estimation unit 44 obtains the timing of an event predicted to occur in the future based on the extraction result, the event information related to the extraction result, and the history of the biological information.
The activity estimation unit 44 can estimate the event occurrence timing using, for example, machine learning. Here, machine learning is a technology that attempts to realize a function similar to the learning ability that human beings naturally perform on a computer. Specifically, iteratively learns from data and a pattern hidden in it. It means to find out.
For example, when the activity estimation unit 44 receives the event information related to excretion such as the excretion time from the receiving unit 41, the activity estimation unit 44 stores the biological information in a predetermined period before and after the input time in association with the event information.

Then, the activity estimation unit 44 stores the biological information every time the event information related to excretion is input, and learns whether or not there is a feature (pattern) common to the biological information stored in association with the excretion record in this way. .. When the biometric information has predetermined common features, the activity estimation unit 44 monitors the biometric information received thereafter and determines whether or not the biometric information has predetermined common features. When the received biological information has a predetermined common feature, the activity estimation unit 44 estimates that it is the timing when the excretory behavior occurs. When the activity estimation unit 44 extracts the biological data related to the event information from the biological information, the activity estimation unit 44 uses the remaining biological information obtained by excluding the biological data corresponding to heartbeat, respiration, etc. from the biological information into the event information. Relevant biometric data may be acquired as the extraction result.
In addition, machine learning is performed on the correlation between the enormous amount of data of event information and biological information, patterns related to the behavior of children 15 are extracted, and detection thresholds and various prediction / estimation functions corresponding to individual differences of children 15 are also provided. By doing so, it is possible to eliminate the anxiety of parents (guardians) and support comfortable childcare.
For example, based on the daily sleep time of the child 15 and the interval of events (lactation time, urination / excretion time), whether the child 15 is sleepy, whether he / she wants to urinate, and wants to urinate / excrete. When estimating the feelings of the child 15, such as whether or not he / she thinks, or whether or not there is a possibility of crying at night based on this estimation result, the estimation result is output. The parent will be able to understand how the child 15 may be feeling. As a result, even if the child 15 does not understand the language yet, the parent can grasp the feelings of the child 15 to some extent, and it is also possible to relieve the stress of the parent.
In addition, when predicting the wake-up time from the time zone, body movement, sleep / wake pattern, interval of events (lactation time, urination / excretion time), etc., parents can make a schedule based on the wake-up time. Being able to support action planning for parents.
In addition, when it is detected that the heartbeat and breathing patterns are different from usual, it is estimated that there is a possibility of physical deterioration, and by notifying the estimation result, the parent can change the physical condition at an early stage. It will be possible to inform.

The schedule generation unit 45 generates a schedule based on the timing at which the event occurs. The schedule generation unit 45 may have the function of the activity estimation unit 44. That is, the boundary that separates the functions of the activity estimation unit 44 and the schedule generation unit 45 is not strict, and if necessary, one may have a function and the other may have a function. That is, the generation unit of the present invention can be composed of at least one of the activity estimation unit 44 and the schedule generation unit 45. The control unit 46 controls each unit of the childcare support device 40. The transmission unit 47 transmits various information to the terminal device 30.

Next, FIG. 5 is a diagram showing an example of a screen displayed on the touch panel 34 of the terminal device 30. The screen shown in this figure is also referred to as a home screen. The home screen is a screen that is the basis of operations performed by a user (application user) of a program (application) executed by the control unit 32.
As shown in FIG. 5A, the image 34A1 of the main photograph is displayed in the center of the upper side of the display screen. As the image 34A1, an image captured by the camera 36 can be used.

Image 34S2 showing the state of respiration is displayed in the ring-shaped portion around the image 34A1. An image 34S1 showing the presence or absence of body movement is displayed on the upper left side of the image 34A1 of the main photograph. The image 34S3 showing the state of the heartbeat is displayed in the heart mark portion at the lower part of the image 34A1.
The image 34S1 showing the presence or absence of body movement is turned on when there is body movement and turned off when there is no body movement. Here, the stronger the movement of the body, the brighter it can be displayed. In the image 34S2 showing the state of respiration, the ring-shaped portion blinks in accordance with the rhythm of respiration. In addition, the thickness of the ring can be changed according to the strength of breathing (deep inhalation, deep exhalation, etc.). In the image 34S3 showing the state of the heartbeat, the heart symbol portion blinks in accordance with the rhythm of the heartbeat. Here, the brightness can be changed according to the strength of the heartbeat. The touch panel 34 displays each image of the images 34S1 to 34S3 based on the activity information.

Further, an image 34B1 for inputting sleep event information is displayed on the upper right side of the image 34A1 of the main photograph. When the image 34B1 is tapped with a fingertip or the like (hereinafter referred to as a tap operation), the image 34B1 lights up. When the image 34B1 is turned on by a tap operation, the operation time is stored in the activity history storage unit 33 (43) as the sleep start time. Further, when the tap operation is performed again while the image 34B1 is lit, the image 34B1 is turned off and the operation time is stored in the activity history storage unit 33 (43) as the sleep end time.

When the image 34B1 is lit, the display screen indicates that the child is sleeping.
For example, as shown in FIG. 5B, the tone of the entire display screen of the touch panel 34 and the frame portion around the screen becomes dark, and the image 34A1 in the center of the screen is switched from the main photo to the sub photo. By doing so, it is possible to indicate that the child is sleeping on the entire display screen of the touch panel 34. For example, by registering the image of the awake child in the main photo and registering the image of the sleeping child in the sub photo, the image of the sleeping child is displayed in the image 34A1 when the image 34B1 is lit, and the image of the sleeping child is displayed during sleep. It is easy to identify whether or not it is.
In FIGS. 5A and 5B, an input button of the input unit 342 to be input in addition to the event information related to sleep is displayed in the area on the lower side (lower side of the screen) of the image 34A1.

FIG. 6 is a diagram showing an example of information stored in the activity history storage unit 43.
The activity history storage unit 43 stores biological information, activity information, and event information together with the date and time. The biological information is biological information obtained by the biological sensor 10. Activity information is body movement,
There are items for breathing, heartbeat, sleep, awakening, and crying at night, and event information includes items for L, milk, R, diapers, and poop. Item L indicates that breastfeeding was performed from the left breast. The item R indicates that breastfeeding was performed from the right breast. The diaper item indicates that the child changed diapers in response to excretion or urination. The poop item indicates that the parent has confirmed that the child has excreted. In addition, there may be a pee item (not shown) as well as a poop item. In this case, the pee item indicates that the parent has confirmed that the child has urinated.
Further, in this figure, the case where one person to be measured is assumed has been described, but it is also possible to store each person to be measured.
In addition, the activity history storage unit 43 can also store data necessary for estimating the timing at which an event occurs. As the data required to estimate the behavior occurrence timing, for example, the biological information in a predetermined period before and after the time when the event information of sleep, breastfeeding, and excretion is input is associated with the event information. And remember.
For the activity history storage unit 43, for example, a semiconductor memory, a magnetic disk device, or the like is used.

FIG. 7 is a sequence diagram illustrating the operation of the childcare support system 1.
Here, before proceeding with this sequence, first, the ID of the communication device 20 is notified to the terminal device 30 by performing short-range wireless communication between the communication device 20 and the terminal device 30. The terminal device 30 transmits this ID and the terminal identification information (which may be a telephone number) assigned to itself to the childcare support device 40. As a result, the childcare support device 40 can associate the biosensor 10 with the terminal device 30. That is, the relationship between the child 15 who is the subject to be measured and the parent who raises the child 15 (carrying the terminal device 30) can be identified.

First, the biological sensor 10 detects the vibration caused by the biological activity of the child 15 and obtains biological information as the detection result (step S101). The biological sensor 10 transmits biological information to the childcare support device 40 by the communication device 20. This transmission of biological information is performed at regular intervals (for example, several seconds).
Next, the childcare support device 40 acquires the states of body movement, respiration, and heartbeat from the biometric information received and notified from the communication device 20 (step S201), and generates activity information (step S202). , The biological information and the activity information are stored in the activity history storage unit 43 together with the time when the biological information is received (step S203). Then, the childcare support device 40 transmits the activity information to the terminal device 30 (step S204).

Next, the childcare support device 40 determines whether or not event information has been received from the terminal device 30 (step S205). When it is determined that the event information has been received, the childcare support device 40 stores the received event information in the activity history storage unit 43 in association with the time when the event information is transmitted together with the received event information (step S206). On the other hand, if the event information is not received, step S206 is skipped.

Next, the childcare support device 40 determines whether or not the activity history reference request has been received from the terminal device 30 (step S207). If the activity history reference request is not received, the process proceeds to step S201, and when the activity history reference request is received, the childcare support device 40 reads the activity information and event information from the activity history storage unit 43 (step S208). ), Sent to the requesting terminal device 30 (step S209). Here, the activity information and the event information in the designated period may be read and transmitted from the terminal device 30, or the activity information and the event information in the predetermined period (for example, up to several days ago) may be read out and transmitted. You may send it.

When the activity information is transmitted from the childcare support device 40, the terminal device 30 receives the activity information (step S301) and displays it on the touch panel 34 (step S302). Next, the terminal device 30 determines whether or not event information has been input from the touch panel 34 (step S303). When the event information is input, the input event information is acquired (step S304) and transmitted to the childcare support device 40 together with the input time. If no event information is input, steps S304 and S305 are not executed and are skipped.
Next, the terminal device 30 determines whether or not the activity history reference request has been input from the touch panel 34 (step S306). When it is determined that the activity history reference request has been input, the terminal device 30 transmits the activity history reference request to the childcare support device 40 (step S307), and receives the activity history transmitted in response to the activity history reference request (step S308). ), Display the activity history (step S309). For example, in this activity history, event information is collectively displayed for a predetermined period such as one day's worth or one week's worth. On the other hand, when the terminal device 30 determines in step S306 that the activity history reference request has not been input, the terminal device 30 skips step S307, step S308, and step S309.

As a result, the activity status is displayed on the touch panel 34 of the terminal device 30, and the past activity history and event information are displayed as needed.
Further, in parallel with the processing of FIG. 7, the childcare support device 40 predicts the occurrence timing of an event predicted to occur in the future by the activity estimation unit 44, and the schedule generation unit 45 is based on the prediction result. Generate a schedule by. When there is a schedule reference request from the terminal device 30, the childcare support device 40 transmits the generated schedule to the terminal device 30.
If it is determined in step S306 that the activity history reference request has not been input from the touch panel 34, the above-mentioned steps S307 to S309 are skipped.

Next, regarding the input of event information, as an example thereof, the display contents when the touch panel 34 inputs the event information related to breastfeeding will be described with reference to FIG.
In FIG. 8A, as already described, the image 34B1 for inputting the sleep event information is displayed on the upper right side of the image 34A1 of the main photograph. In addition, the image for inputting event information other than sleep is arranged in the lower half area of the display screen (corresponding to the input unit 342) under the image 34A1 of the main photograph, and the pattern is drawn in the circle. There are five icons.
The five icons and the icons of the image 34B1 arranged in the lower half of the display screen of the touch panel 34 are arranged in the area corresponding to the input unit 342 of the touch panel 34. From the upper left, the image 34B2 for inputting the event information of breastfeeding L, the image 34B3 for inputting the event information of milk, and the image 34B4 for inputting the event information of breastfeeding R are shown, respectively, and from the left of the lower row. , Image 34B5 for inputting event information of diaper change and image 34B6 for inputting event information of excretion are shown.

Here, breastfeeding R means breastfeeding from the right breast. Breastfeeding L means breastfeeding from the left breast. As described above, the child-rearing support system 1 of the present embodiment can distinguish and record which breast is fed from the left or right breast.
In general, if the mother is more likely to hold the baby or the newborn is more likely to sleep, the mother may breastfeed with only one breast. When a mother breastfeeds only on one breast, the other breast milk does not go out and some breast milk remains in some breasts, making it easier for the breast to become clogged. If the mammary glands become clogged and inflamed, mastitis occurs. If the mother has mastitis, she is treated with antibiotics and other medications. You may not be able to breastfeed your child while the parent is taking the drug.
In the child-rearing support device 40 of the present embodiment, it is possible to distinguish and record which breast is breast-fed on the left or right. For this reason, the mother can consciously breastfeed evenly on the left and right sides, and can reduce the chance of getting mastitis.

On the home screen shown in FIG. 8 (a), when a tap operation is performed on the image 34B4 for inputting the event information of breastfeeding R, a display screen for recording the breastfeeding time shown in FIG. 8B is displayed. Will be done. The childcare support system 1 of the present embodiment can also measure and record the time required for breastfeeding in order to record the breastfeeding time.
In FIG. 8B, an image 34B4-1 showing a guide "Record the time when the start is pressed" is displayed in the upper center of the screen of the display screen for recording the breastfeeding time. Below the image 34B4-1, a ring-shaped image 34B4-2 showing the passage of measurement time is displayed. When the timer is started, the elapsed time is displayed by increasing the area displayed in the ring-shaped image of the image 34B4-2 in the color indicating the elapsed time clockwise with the passage of time. .. Therefore, the mother can check the passage of breastfeeding time at a glance.

Further, below the ring-shaped image 34B4-2 showing the passage of the measurement time, an image 34B4-3 showing the numerical display of the measurement time is displayed. Below the image 34B4-3, an image 34B4-5 for operating the start and stop of the timer and an image 34B4-4 for resetting the timer are displayed. In the image 34B4-5, the displayed symbol changes according to the operating status of the timer. For example, when the timer is stopped, the characters "start" and the like are displayed, and while the timer is being counted, the characters "stop" and the like are displayed.
Further, in the lower left of the ring-shaped image 34B4-2, an image 34B4-6 for inputting event information of breastfeeding L is displayed. In addition, an image 34B4-10 showing a guidance of "recording in a childcare memo" is displayed in the center of the lower part of the display screen for recording the breastfeeding time. When the tap operation is performed on the image 34B4-10, the operation time and the breastfeeding time are stored in the activity history storage unit 43 as breastfeeding event information. Here, in the breastfeeding event, it is identifiable whether the breastfeeding R or the breastfeeding L was performed between the start time and the end time. For example, the breastfeeding R button (image 34B4) is touched on the screen of FIG. 8A, and after transitioning to the screen of FIG. 8B, the start button (image 34B4-5) is touched to feed the breastfeeding time. From the start of counting until the stop button (image 34B4-5) is touched, the breastfeeding R is set. For example, after that, the "record in childcare memo" button (image 34B4-10) is touched. Then, it is stored in the activity history storage unit 43 as the breastfeeding event information of the breastfeeding R. Further, on the screen of FIG. 8B, after the breastfeeding time is counted until the start button (image 34B4-5) is touched and the stop button (image 34B4-5) is touched, the "childcare memo" is displayed. If the button of breastfeeding L (image 34B4-6) is touched before the button of "record" (image 34B4-10) is touched, the mode is switched to the mode of counting the breastfeeding L. Then, from the touch of the start button (image 34B4-5) to the touch of the stop button (image 34B4-5), the breastfeeding event information of the breastfeeding L is temporarily saved. Then, when the "Record in childcare memo" button (image 34B4-10) is touched, event information including breastfeeding event information of breastfeeding R and breastfeeding event information of breastfeeding L is stored in the activity history storage unit 43. Will be done.
In this way, which of these breastfeeding R and breastfeeding L is included is stored as one breastfeeding event information.

Generally, the standard breastfeeding time is about 5 to 10 minutes per breast. Breastfeeding for a long time with one breast may cause the child 15 to become full, and the child 15 may not be able to drink breast milk from the other breast, resulting in clogging of the milk or poor milk production.
In the ring-shaped image 34B4-2 showing the passage of the measurement time, when the timer is started, a part of the color of the ring is displayed in the color indicating the elapsed time, and when the measurement time reaches 10 minutes, the entire ring shows the elapsed time. It is displayed in the representative color. In this way, since the elapse of the measurement time is displayed on the image 34B4-2 with an upper limit of 10 minutes, the mother may breastfeed until the color changes to about half of the image 34B4-2 ring, for example. A rough guide can be given, and the breastfeeding time can be easily adjusted without excess or deficiency.

Further, on the home screen shown in FIG. 8A, when a tap operation is performed on the image 34B3 for inputting milk event information, a display screen for recording the amount of milk shown in FIG. 8C is displayed. Is displayed.

Below image 34B6-1, a ring-shaped image 34B6-2 showing the color of excrement is displayed. The image 34B6-2 is divided into seven regions in the circumferential direction and displayed in different colors. When a tap operation is performed on any area of the image 34B6-2, a check mark is displayed in that area (reference numeral 34B6-4), and the color of excrement can be selected. The area of the image 34B6-2 corresponds to the input unit 342 on the touch panel 34.
In addition, an image 34B6-10 showing a guide to "record in a childcare memo" is displayed in the center of the lower part of the screen of the display screen for recording excretion. When the tap operation is performed on the image 34B6-10, the information representing the operation time and the selected color is stored in the event information table 36B as excretion event information.

The color of newborn excrement is often clearly different from that of adults. The color is yellow to ocher, often greenish, and there may be differences in color between breast-fed and milk-fed. In addition, the color varies from person to person. In addition, parents should be aware that if the color is entirely white, they may be infected with a virus.
In this way, the color of newborn excrement has a characteristic that adults do not have, and if you do not know this characteristic, you may be worried about it or you may go unnoticed even though it is a color you should be careful about. There is. Since the childcare support system 1 of the present embodiment can select and record the color when recording excretion, the parent can know the color characteristics of his or her child, and event information. When comparing with reference to the past history of, if there is a clear difference, it is possible to understand that some kind of change in physical condition may have occurred and to be careful.

Next, the display contents when the touch panel 34 displays the event information will be described with reference to FIG. The touch panel 34 can collectively display event information related to sleep, breastfeeding, and excretion, which is input within a predetermined period of the activity history stored in the activity history storage unit 43 (33). This activity history may be displayed when the activity history reference button is placed on the main screen and this button is tapped, or the entire main screen is flicked to the right or left. It may be displayed when it is displayed.
An image 34R1 showing a date is displayed in the center of the upper part of the screen shown in FIG. 10A.

The image area 34B21 is an image area showing a record of breastfeeding. In the image area 34B21, the portion marked with the image 34B22 indicating the breastfeeding mark indicates that the child 15 has been breastfeeded. In addition, the vertical position of this breastfeeding mark indicates the time when breastfeeding was performed.
The image area 34B31 is an image area showing the recording of milk. In the image area 34B31, the portion marked with the image 34B32 showing the milk mark indicates that the child 15 was fed milk. In addition, the vertical position of this milk mark indicates the time when milk was given.
The image area 34B51 is an image area showing a record of changing diapers. In the image area 34B51, the portion with the image 34B52 indicating the diaper mark indicates that the diaper of the child 15 has been replaced. The vertical position of the diaper mark indicates the time when the diaper was changed.
The image area 34B61 is an image area showing a record of excretion. In the image area 34B61, the portion marked with the image 34B62 indicating the excrement mark indicates that the child 15 has excreted. In addition, the vertical position of the excrement mark indicates the time when excretion was performed.
In the example shown in FIG. 10A, the diaper is changed and breastfeeding is performed at about 7 am, then the patient sleeps from 7:30 to 10:30, excretes at about 10:30, and drinks milk at about 11 o'clock. It is shown that he slept from about 11:45 to 14:00.

Further, when the tap operation is performed on the image 34R3 for displaying the cumulative total on the screen shown in FIG. 10 (a), the event information of the predetermined period (for example, one week here) shown in FIG. 10 (b) is displayed. A screen showing the cumulative total is displayed.
On the screen shown in FIG. 10B, the date is displayed in the center of the upper part of the screen and the time is displayed in the longitudinal direction (vertical direction) of the screen on the left side of the screen as in FIG. 10A. On the screen shown in FIG. 10 (b), records of sleep, breastfeeding, milk and the like are displayed in the same manner as in FIG. 10 (a). That is, in the sleep record, the part colored differently from the background was during sleep, and in the breastfeeding and milk record, the part marked with breastfeeding and milk was breastfeeding and feeding. Indicates that is being recorded.

In the example shown in FIG. 10 (b), it is shown that milk is always given at least once between 0:00 and 3:00 at night throughout the week. In addition, it is relatively (1) from 3:00 dawn to 6:00 am (image area 34F1), from 11:00 to 12:00 noon (image area 34F2), and from 19:00 to 22:00 in the evening (image area 34F3). It can be understood that the child 15 is often sleeping (about 4 days out of 7 days a week).

Further, at the lower part of the screen, an image 34B63 showing the cumulative total of excretion and an image 34B53 showing the cumulative total of diaper change are displayed.
In the example shown in FIG. 10B, excretion varies from 0 to 3 times a day and is not stable on a daily basis, but a bird's-eye view of the week shows that the day after the day when there was no excretion. It is shown that there were two patterns in which three excretion were recorded. It is also shown that diaper changing is performed about 10 times a day.

By displaying daily event information in this way, it is possible to know the time of day when one sleeps well, the pattern of excretion, and the number of diapers consumed in one week. Knowing when to sleep well makes it easier for parents to plan, for example, to finish their household chores during that time. In addition, if the pattern of excretion is known, even if there is no excretion at all, it can be predicted that there will be excretion the next day, and there is no need to worry more than necessary. Furthermore, if you know the number of diapers you consume in a week, you can predict the number of days until the diapers you have at home will be consumed, and parents will take planned actions such as purchasing diapers before they run out. be able to.
It is said that if a child's circadian rhythm (also called circadian rhythm or body clock) is not formed, the secretion of growth hormone deteriorates, which may cause night crying, sleep disorders, developmental disorders, etc. By displaying the child so that the parent can get a bird's-eye view on a weekly basis, the parent can grasp the status of the circadian rhythm of the child 15, so that the parent can manage the rhythm such as sleep and awakening, for example. Can help.

As described above, by using the childcare support system 1 according to the present embodiment, even if the parent is away from the child 15, the child's breathing (sleeping breath) can be easily performed based on the information displayed on the terminal device 30. ), Etc., event information can be easily input from the touch panel 34 displayed on the terminal device 30, and the input event information is collectively displayed, so that the child's behavior You can grasp the pattern.

Further, although the biological sensor 10 in the present embodiment measures an electric signal in response to vibration, it suffices if it can detect the state of the child. For example, the detection unit 2 may make a sound caused by a child's crying or the like. It may be a microphone that detects the heat distribution (thermography) based on the infrared rays emitted from the child.

The activity history generation unit 42 in the present embodiment acquires activity information of body movement, respiration, and heartbeat, but is not limited to this. The activity history generation unit 42 may acquire, for example, a night crying, snoring, or sleeping state from an electric signal corresponding to vibration. In particular, the activity history generation unit 42 may acquire awakening, that is, an awakened state with respect to the sleep state. If the awakening of the sleeping child 15 is transmitted to the terminal device 30 and displayed on the terminal device 30, it is possible to take measures such as picking up the child before waking up and crying.
Further, if a predetermined feature is found from the electric signal measured by the biosensor 10 during a predetermined period before and after the sleeping child 15 wakes up, the activity estimation unit 44 wakes up the child 15 as an action occurrence timing. The time can be estimated. In this case, the childcare support device 40 can notify the parent in advance by notifying the terminal device 30 that the child 15 is about to wake up. For this reason, the parent can take measures such as staying with the child 15 when he / she wakes up.
