Description

The present invention relates to a system for supporting a caregiver's nursing care work when providing physical care, and more particularly, to a caregiver support system using a head-mounted wearable terminal.

In Japan, which is said to be a super-aging society, there are not enough human resources such as caregivers (a wide range of personnel involved in physical care, such as care workers and helpers; the same applies hereinafter) in nursing care settings, and chronic labor shortages. Many nursing care facilities are facing a shortage. Furthermore, as the so-called baby boomer generation ages, the number of people requiring care (people who require care and assistance) is expected to further increase. As a result, an increasing number of caregivers will be needed, but securing such personnel is becoming extremely difficult. According to documents released by the Ministry of Health, Labor and Welfare, it is predicted that there will be a shortage of approximately 220,000 caregivers in 2023 and 320,000 caregivers in 2025.

As mentioned above, nursing care facilities are facing a chronic labor shortage, and as a result, there is a lack of educational systems for training caregivers, and even if new caregivers are hired, there are cases where sufficient training is not possible. There are also many. In addition, experienced caregivers such as veterans and mid-career caregivers are too busy with the work at hand to educate or support new caregivers. Under such circumstances, new caregivers are unable to acquire sufficient skills and are therefore unable to perform nursing care services as desired. It is also said that approximately 90% of caregivers experience refusal of care, and this number is on the rise. In such a situation, caregivers may not feel that their work is worthwhile, leading to them leaving the job. In fact, nursing care workers consistently have the highest turnover rate of any industry.

As described above, there is a problem in that the working environment at nursing care sites is slow to improve due to the vicious cycle in which new caregivers tend to leave their jobs due to the labor shortage being one of the causes.

In order to deal with the above-mentioned problem of labor shortages in nursing care settings, it has been pointed out that there is a need for the introduction of IT (information technology) and ICT (information and communication technology) in nursing care settings. progress is not being made. As a result of this, the efficiency of various tasks related to nursing care has not been sufficiently improved, and an environment has not been created to reduce costs by improving work efficiency or provide nursing care to a large number of people with limited personnel.

By advancing the use of IT and ICT, various tasks related to nursing care can be made more efficient, so it is desirable to reduce work costs and enable more work to be done with limited human resources.

In order to solve this problem, the Ministry of Health, Labor and Welfare is promoting the introduction and spread of ICT among nursing care providers. The content of this ICT shift is mainly the digitization of nursing care records, and the aim is to aggregate this digitized nursing care information to accumulate big data, which will be analyzed and used to solve problems.

However, these computerized nursing care records are data manually entered by caregivers and others who provide care in the field using computers, tablet PCs, etc., and are subject to input errors and omissions. In addition, even if the same care content is provided, there may be variations in the description or arbitrary elements, such as differences in the wording or differences in judgments as to whether or not it should be kept as a care record. Furthermore, it can be said that even inputting this nursing care record is a heavy burden for caregivers who have many nursing care tasks to perform.

Patent Document 1 describes "a system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia, and related medical conditions, the system comprising: body position, temperature, acceleration, moisture, resistance, stress, and blood oxygenation; a sensor configured to detect at least one patient characteristic selected from the group comprising: and in response to the sensor, said at least one sensed characteristic to assist in determining a series of proposed actions for said patient. and a display for notifying a caregiver of the series of suggested actions. In summary, this is a system that notifies caregivers of proposed actions for the corresponding patient based on signals from sensors that detect patient characteristics such as body position and temperature.

However, with the technology described in Patent Document 1, it is necessary to prepare and monitor many sensors for the patient, which not only requires a lot of cost, but also requires an environment where these sensors are not installed. There was a problem that the system could not be operated.
There is also the problem that if a problem other than an abnormality in patient characteristics obtained by the sensor occurs, it cannot be detected.

JP2018-008069

Therefore, an object of the present invention is to be able to provide support in real time so that even inexperienced caregivers can perform nursing care service tasks appropriately, thereby providing optimized nursing care services to the cared person. The purpose of the present invention is to provide a caregiver support system that can be implemented even in an environment where facilities are not available.

The above object of the present invention is achieved by the following means.

3. 3. The caregiver support system using a head-mounted wearable terminal according to claim 1 or 2, wherein the support information is a proposal for the content of a conversation that the caregiver has with the cared person.

4. A caregiver support system implemented by a cared person wearing a heart rate monitor,
4. The caregiver support system using the head-mounted wearable terminal according to claim 3, further comprising means for transmitting to the caregiver the changes in heart rate of the cared person in response to calls from the caregiver. .

5. According to claim 1 or 2, when providing meal assistance, nutritional management is performed by photographing leftover food using a camera function, transmitting the video data to an external computer, and grasping the ingested calories and nutrients. A caregiver support system using the head-mounted wearable terminal described above.

According to the invention described in 1 above, support information corresponding to the situation at the nursing care site is transmitted to caregivers in real time, and this can be confirmed by audio or video, so even inexperienced caregivers can be able to perform nursing care service tasks appropriately. Even if some kind of trouble occurs during nursing care work, support information such as solutions can be obtained in real time, so caregivers can perform nursing care work with the peace of mind that they can receive support at any time. can be applied.

Furthermore, according to the invention described in 1 above, the head-mounted wearable terminal covers all necessary functions and equipment, so support information can be accessed even in environments where equipment such as cameras and displays are not provided. Obtainable. This is especially significant in the field of home-visit nursing care.

Further, according to the invention described in 1 above, all functions such as taking pictures using the camera function, communicating with an external computer, creating support information using the external computer, and checking support information using the speaker function or display function can be performed automatically and hands-free. This allows the caregiver to concentrate on providing care services to the care recipient. With the spread of the new coronavirus infection, it has become common for nursing care workers to wear face shields while performing nursing care work, and caregivers have little reluctance to wear head-mounted wearable devices. It can be said that the hurdles for widespread use are low.

The invention shown in 2 above has a configuration in which video data taken at nursing care sites is sequentially stored in an external computer, a big data database is created from this stored video data, and a big data database is created based on this stored big data. , in which nursing care model data is constructed using artificial intelligence algorithms. Since this nursing care model data is constructed from big data that is accumulated sequentially, it can be said that it becomes more mature as the amount of data increases.

Support information corresponding to the received video data is created using nursing care model data built based on this accumulated big data, so support information necessary at the nursing care site is provided to caregivers in real time. Is possible.

With this configuration, the big data database accumulates video data sent daily from each care site, so the care model data built based on this can constantly grow and mature. Since support information is created based on this nursing care model data that grows and matures, the caregiver support system according to the present invention can be said to be a growing system or a learning system, and the accuracy of the support information continues to increase. , it can be said that it continues to be optimized.

In the invention described in 3 above, the support information created and transmitted by an external computer includes a conversation that a caregiver has with the care recipient (including a unilateral "call" or "call out" from the caregiver. Same.) It is structured according to the content. The reason why the conversation with the cared person is included in the support information is as follows.

Many care recipients suffer from dementia, and many do not respond obediently to the calls of their caregivers. Not only do they not respond to calls, but in some cases, they become angry at the words and actions of their caregivers, leading to verbal abuse and violence.

Care recipients with such problem behavior are often cared for by excellent caregivers with long care careers and excellent caregiving skills, which tends to relatively suppress problem behavior. As described above, the present inventors have focused on the fact that there is a difference in the attitude of a cared person with problematic behavior depending on whether the care is provided by an excellent caregiver or the case where the care is provided by a less experienced caregiver. The inventor investigated the reason for this difference through interviews at nursing care sites, and found that there is a difference in the content and quality of "conversations and greetings with the care recipient."

In other words, an excellent caregiver is well aware of the types of behavior that a care recipient with behavioral problems likes or dislikes, and is also aware of the individual care recipient's medical condition, physical condition, cognitive ability, psychological state, etc. Overall, it was found that the person being cared for responded calmly and engaged in ``conversation and encouragement'' that did not lead to problematic behavior.

Therefore, in the invention described in 3 above, the content of "conversation/address to the cared person" is proposed as support information.
Based on this support information, if you practice appropriate conversation and encouragement with the cared person, you can prevent the cared person from engaging in problematic behavior. In addition, by suppressing problematic behavior, nursing care service work can be performed more efficiently.

The invention shown in 4 above makes it possible to confirm whether or not the cared person is responding to calls from the caregiver by having the cared person wear a heart rate monitor and grasp changes in the cared person's heart rate. . The reason why we focused on this heart rate change is as follows.

Among the cared for, there are many people with dementia or those who are hard of hearing, and many of them do not respond or are unable to respond to calls from their caregivers. In nursing care settings, caregivers are required to speak to the cared person many times, but the cared person often does not respond, making it especially difficult for inexperienced caregivers to understand the effectiveness of their voice calls. Or, they may not be able to understand it, which may lead to a decrease in job satisfaction and motivation, and may even lead to them leaving the company.

On the other hand, even if the caregiver does not respond or is unable to respond to the caregiver's voice, there are cases in which the caregiver still responds to the voice. As one of the reactions, it is known that a change in heart rate appears in the cared person when called by the caregiver. If a caregiver can use this phenomenon to grasp changes in the cared person's heart rate, he or she can determine whether or not the cared person is responding to the call.

Therefore, in the invention shown in 4 above, a configuration is adopted in which the cared person is fitted with a heart rate meter to detect changes in the cared person's heart rate in response to calls from the carer, and to transmit this to the carer.
With the invention described in 4 above, it is possible to grasp the reaction of the cared person to a call out to them, so it is possible to prevent and suppress the above-mentioned decline in job satisfaction and motivation, which eliminates one of the causes of turnover. can do. In turn, this can be expected to have the effect of reducing the number of people leaving their jobs.

According to the invention set forth in item 5 above, by using the camera function of the head-mounted wearable terminal to photograph the leftovers of the cared person's meals, the ingested food, calories and nutrients obtained from the food can be captured. etc. can be accurately grasped.

The reason for focusing on leftover food in 5 above is as follows.
In nursing facilities and the like, meals served to care recipients are prepared in consideration of the individual care recipient's health condition, chronic disease, allergies, physical condition, etc., so that they can ingest the necessary calories and nutrients. In other words, nutrition is managed in terms of diet.

On the other hand, even if a meal is served that provides the necessary calories and nutrients, the care recipient does not always finish the meal without leaving any leftovers. If you have leftover food, it means that you are not ingesting the calories and nutrients you need, and your nutritional management cannot be said to be perfect. Furthermore, when a cared person becomes unwell for some reason, it is common to check the contents of the previous meal. Even in this case, if leftover food is not accurately known, there is a problem in that it is not possible to appropriately determine whether or not the reason for becoming unwell is due to the meal.

In some cases, caregivers keep records of leftover meals, but even the task of creating these records is a burden in nursing care settings that are understaffed, so this information can be automatically tracked. It is significant if it can be done.

Therefore, in the invention shown in 5 above, a head-mounted wearable terminal worn by a caregiver is used to photograph leftover food when cleaning up a meal, and the photographed video data is sent to an external computer. This external computer allows you to accurately determine the actual meal content and the calories and nutrients taken in from that meal. As a result, it is possible to accurately determine whether the cared person is properly ingesting nutrition, and whether or not the contents of the meal are a contributing factor when the person becomes unwell.

A caregiver support system 1 (hereinafter also referred to as "caregiver support system 1" for short) using a head-mounted wearable terminal according to the present invention will be described with reference to the drawings.
In this specification, cared person Y refers to an elderly person, a disabled person, etc. who requires care or assistance and receives services, and carer Z refers to a person who provides nursing care services to cared person Y. A person who engages in care work, such as a care worker or a helper, especially a person who provides physical care.

FIG. 1 is a system diagram showing the basic configuration of the nursing care support system 1. As shown in FIG.
As shown in FIG. 1, the nursing care support system 1 includes:
(1) A means of photographing the state of nursing care (photographing means);
(2) means for transmitting and receiving photographed video data (transmission means);
(3) means for accumulating video data in a database (accumulation means);
(4) means for constructing nursing care model data (construction means);
(5) means for regularly updating nursing care model data (updating means);
(6) means for creating support information (creation means);
(7) Means for sending and receiving the created support information (reply means);
(8) means for pronouncing or displaying the received support information (display means);
The configuration has the following.

The means (1) to (8) above will be explained in order.
The photographing means (1) above is a means for photographing the caregiver Z performing the care service work for the cared person Y. It is preferable to shoot a video and collect surrounding sounds and record them as video data. Unless otherwise specified in this specification, photography is accompanied by sound recording, and the video data includes sound.

The photographing means may be performed using a camera function W1 provided in the head-mounted wearable terminal W. Thereby, it is possible to take pictures with the line of sight of caregiver Z and record the state of caregiving as video data.

The transmitting means (2) above transmits the video data photographed and recorded by the head-mounted wearable terminal W to the external computer C, and the external computer C receives the video data using the communication means. It is a transmitting and receiving means.
Although there are no limitations on the communication means used, wireless communication is preferred. Examples include wireless LAN using Wi-Fi and mobile communication systems used for communication in mobile phones and the like. In particular, it is preferable to use a fifth generation mobile communication system (commonly known as "5G") because it allows large amounts of data to be transmitted and received at high speed, and high-resolution video data can be transmitted and received.

The storage means in (3) above stores the video data received by the external computer C in (2) above in a big data database (hereinafter simply " This is a function that stores data in a database (also called a database).
Since the video data received by the external computer C is stored in the database each time, the amount of data stored in this database gradually increases, and the accuracy of the data is gradually improved in the creation means described in (6) above, which will be described later. Can be done.

Further, in addition to the above-mentioned video data, it is preferable that a care model prepared in advance is recorded in the database. The nursing care model will be described later in the section (4) Construction means above. By recording a nursing care model prepared in advance, a certain amount of information can be secured even if the collection of video data is insufficient.

The construction means (4) above is a means for constructing nursing care model data using an artificial intelligence algorithm based on big data such as video data stored in a database.
This nursing care model data is data whose contents are models that serve as norms, models, or standards in nursing care services. In other words, the nursing care model is a normative model, model model, or standard model in nursing care services. A model that serves as a norm, model, or standard for nursing care procedures, coping methods, etc. is constructed according to the nursing care situation.

In addition, the construction means in (4) above is constructed based on the video data transmitted from the head-mounted wearable terminal W, and also refers to a nursing care model prepared in advance as part of the big data. Preferably, care model data is constructed. As a result, even if the collection of video data is insufficient, a certain amount of information can be secured, and the accuracy of the nursing care model data can also be secured.

Examples of the above-mentioned care models prepared in advance are given below.
As described above, the nursing care model data is data whose contents are models that serve as norms, models, or standards in nursing care services. Therefore, this nursing care model data can be constructed by learning the nursing care service work performed by veterans with extensive nursing care experience and caregivers who are considered to be excellent in nursing care settings (also simply referred to as "excellent caregivers"). preferable.
Specifically, first, at a stage before the nursing care support system 1 according to the present invention is operated, an excellent caregiver is fitted with a head-mounted wearable terminal W, and nursing care service work performed at a nursing care site is performed. The situation will be photographed and video data will be collected.

This collected video data is recorded in a database, and based on this, nursing care model data is constructed. Support information is created based on the nursing care model data constructed here.
After that, after the nursing care support system 1 starts operating, the learning content from the newly sent video data is reflected in this basic nursing care model data, so it is more accurate and optimized. Nursing care model data can be constructed. Note that the process of reflecting the newly sent video data on the basic nursing care model data also overlaps with the content of the above-mentioned (5) updating means described later.

This care model data is constructed as an individual specific care service work means. For example, in the case of walking assistance, "caregiver Z should stand diagonally behind cared person Y," or "if cared person Y is right-handed, stand on the left, and if cared for left-handed, stand on the right." ”, “If cared person Y has paralysis, stand on the side where the paralyzed person is”, “Pay attention to the shift of cared person Y’s center of gravity”, “Be sure to walk at the same rhythm , ni, ichi, ni'' and ``right, left, right, left'' are constructed as nursing care model data.

The updating means (5) above is means for periodically updating the above-mentioned nursing care model data. Specifically, this is a means of updating the nursing care model data to the latest data after reflecting the video data accumulated in the database each time. It can also be said to be a means of optimizing nursing care model data.

By means of (1) to (4) above, the video data that is the basis for constructing nursing care model data gradually increases, and the amount of video data, that is, the amount of data as big data, increases. It can be said that the greater the amount of underlying data, the higher the accuracy of the nursing care model.
Therefore, by providing this updating means, the accuracy of the nursing care model is gradually improved, or in other words, it is optimized. This nursing care support system 1 can be said to be a system that learns and grows.

The creation means (6) above is a means by which the external computer C creates support information corresponding to the received video data based on the nursing care model data.
Support information is information to support Caregiver Z's nursing care service work at the nursing care site, and includes information such as nursing care procedures and how to deal with problems when they occur, expressed as text, symbols, diagrams, images, video, or audio. This is the information given.

The support information is created by an artificial intelligence algorithm based on the care model data constructed in (4) above and updated in (5) above. The nursing care model data records nursing care procedures and coping methods according to the nursing care situation, and the situation at the nursing care site can be grasped from the transmitted video data, and the optimal nursing care procedures and countermeasures can be determined according to the situation. The method is selected and created as supporting information.
The specific contents of this support information will be described later.

The reply means in (7) above sends support information created in response to the received video data from the external computer C to the head-mounted wearable terminal W, and the head-mounted wearable terminal W This is a means for transmitting and receiving support information using communication means.
As in (2) above, there is no limitation on the communication means used, but wireless communication is preferable. Examples include wireless LAN using Wi-Fi and mobile communication systems used for communication in mobile phones and the like. In particular, it is preferable to use a fifth generation mobile communication system (commonly known as "5G") because it allows large amounts of data to be transmitted and received at high speed, and high-resolution video data can be transmitted and received.

The display means (8) above is means for pronouncing or displaying the received support information on the head-mounted wearable terminal W worn by the caregiver.
Although details will be described later, the head-mounted wearable terminal W is configured to include either one or both of a speaker function W2 and a display function W3. This speaker function W2 (including the form of earphones, etc. will be described in detail later) is used to pronounce support information that can be recognized through the sense of hearing such as voice, or the display function W3 is used to pronounce text. , visually recognizable support information such as symbols, diagrams, images, or videos is displayed. By confirming this pronunciation or displayed support information, caregiver Z can reflect it in the care service work for care recipient Y.

Next, the head-mounted wearable terminal W worn by the caregiver Z will be described according to FIG. 2.
A wearable terminal is an information terminal that is worn and used by humans. Wristband and wristwatch types that are worn on the wrist, armband types that are worn on the arm, glasses types that are worn on the head and face, headband types, and headset types are popular.

The wearable terminal used in the present invention is a head-mounted wearable terminal W. There are no limitations on the specific configuration, and any publicly known head-mounted wearable terminal can be employed without any particular restrictions. As mentioned above, the glasses type, headband type, or headset type that is worn on the head/face can be exemplified. A glasses-type wearable terminal is preferable because the caregiver Z can take pictures with his or her own line of sight.

As shown in FIG. 2, the head-mounted wearable terminal W has a camera function W1 and one or both of a speaker function W2 and a display function W3.

The camera function W1 is a function of photographing and recording video, and also records sound along with the video. This camera function allows the caregiver Z to photograph the caregiver Z performing the nursing care service work for the cared person Y.
There is no particular limitation on the specific configuration of the camera function W1, and any publicly known configuration can be adopted as the camera function for photographing and recording video without any particular restriction.

The speaker function W2 is a function that produces support information that can be recognized through the sense of hearing, such as voice. Thereby, the caregiver Z can recognize the support information through hearing.
There is no particular limitation on the specific configuration of the speaker function W2, and any publicly known configuration can be employed as a device for producing sound without any particular limitations. For example, earphones or headphones can be used.
Further, the speaker function W2 in the present invention includes a configuration generally called an intercom. Intercom is an abbreviation for intercommunication, and is a communication tool that has speaker and microphone functions and can communicate with multiple people at the same time. Sometimes called an intercom.
As described above, an intercom is illustrated as a speaker function, but similarly to the intercom configuration, the configuration of the present invention is preferably configured to include a microphone function as well as a speaker function.

The display function W3 is a function to display visually recognizable support information such as characters, symbols, charts, images, or videos. Thereby, the caregiver Z can visually recognize the support information.
There are no particular limitations on the specific configuration of the display function, and any publicly known configuration can be employed as a device for displaying characters, images, etc. without any particular limitations. For example, a form such as a display function in smart glasses can be exemplified.

In addition, the head-mounted wearable terminal W is configured to include communication means (not shown).
Although there is no limitation on the communication means employed, wireless communication is preferable. Examples include wireless LAN using Wi-Fi and mobile communication systems used for communication in mobile phones and the like. In particular, it is preferable to use a fifth generation mobile communication system (commonly known as "5G") because it allows large amounts of data to be transmitted and received at high speed, and high-resolution video data can be transmitted and received.

It is preferable that the head-mounted wearable terminal W has a function as a face shield.
Currently, caregivers are required to wear face shields in nursing care settings as a countermeasure against the new coronavirus infection. Therefore, it is particularly preferable that the face shield W4 is attached or can be attached to the head-mounted wearable terminal W (see FIG. 2).

Previously, Caregiver Z would have tended to find it bothersome to have some kind of device attached to their body, but due to the spread of the new coronavirus infection, many caregiving settings have made it compulsory to wear face shields. . Due to these circumstances, there is less resistance to wearing a wearable terminal together with a face shield. It would be convenient if the caregiver Z could take this opportunity to wear the head-mounted wearable terminal W and implement the system according to the present invention.

FIG. 2 shows an example of the wearable terminal W.
FIG. 2 is a diagram showing the caregiver Z wearing the head-mounted wearable terminal W. The head-mounted wearable terminal W is equipped with a camera function W1, a speaker function W2, and a display function W3. It is preferable that the camera function W2 is provided at a position close to the eyes of the caregiver Z, the speaker function W2 is provided at a position close to the ears, and the display function W3 is provided at a position where the caregiver Z can see visually.
Moreover, it is preferable that a face shield W4 is provided in a manner that covers the face of the caregiver Z. Thereby, a face shield worn to prevent droplet infection and the like can be worn together with the head-mounted wearable terminal W necessary for implementing the present invention. In addition, since it is mandatory for caregiver Z to wear a mask at nursing care sites, the range where face shield W4 is provided is the range that covers other parts of the face (especially the eyes and their surroundings). It is preferable.

Next, specific contents of the support information will be illustrated.
The caregiver support system 1 is characterized in that the content of the support information is a conversation that the caregiver Z has with the care recipient Y. The reason why the conversation with care recipient Y was selected as the content of the support information is as follows. Note that this "conversation" includes a unilateral "call" or "address" from caregiver Z.

As mentioned above, by optimizing the content of the conversation for cared person Y who has behavioral problems, care service work can be performed smoothly. Therefore, in the present invention, the content of the "conversation with the cared person" is proposed as the support information.

The care support system 1 preferably has the following configuration in order to provide support information as "conversation to the care recipient."

First, the content of conversations and calls/addresses to care recipient Y by an excellent caregiver (such as a caregiver who is appropriate for caring for care recipient Y with behavioral problems) is transferred to an external computer C using an artificial intelligence. The system is trained using the algorithm, stored in a big data database, and reflected in the construction of nursing care model data. This configuration is the configuration of the storage means (3) above and the construction means (4) above.

Next, the system analyzes the sent video data to understand the situation at the nursing care site, selects the optimal nursing care model data according to the situation, and creates support information. The support information created at this time is the specific content of the conversation/address to the cared person. Note that the content of the support information at this time may include other information such as a nursing care method.

The created support information is sent back to the head-mounted wearable terminal W worn by the caregiver Z, and the caregiver Z can refer to this information and have a conversation with or address the care recipient Y.
As a result, by practicing appropriate conversation and addressing the cared person Y, it is possible to prevent the cared person Y from engaging in problematic behavior. In addition, by suppressing problematic behavior, nursing care service work can be performed more efficiently.

Examples of conversation content as support information include the following:
First, support information may be used as support information to gain the trust of care recipient Y. Care recipient Y may not be able to accurately grasp the surrounding situation due to declines in visual, auditory, and cognitive abilities. Therefore, it is preferable for caregiver Z to convey that he or she is "here." This is because if Caregiver Z is not aware that Caregiver Z is nearby and suddenly starts providing care, Caregiver Y may become surprised and exhibit problematic behavior such as angry behavior or refusal to provide care. be. If external computer C determines that care recipient Y is not aware of caregiver Z based on the transmitted video data, it can first create support information to let care recipient Y know that caregiver Z is nearby. preferable. Specifically, say things like, "Hello, Mr. ____,""I'm going to do ____, is that okay?", "Could you please do ____ with me?" Create supporting information about what you are proposing.

Next, it is important to communicate from a larger purpose when talking and addressing people in nursing care settings. If you give detailed instructions such as ``Please stand up'' or ``Please hold me here,'' Care recipient Y may not be able to understand what is being done, which may lead to him refusing care. Therefore, after conveying the larger purpose such as ``Let's go out to eat'' or ``Would you like to take a bath?'', give detailed instructions such as ``Now, please stand up'' or ``Let's move to the wheelchair.'' It is preferable to convey the following information, and it is preferable that supporting information is created taking such matters into consideration.

Next, it may be preferable for the caregiver Z to actively talk to the cared person Y even during the nursing care work. In such cases, we provide support information that encourages conversation, such as ``Let's talk more.'' ``Why don't you talk about the flowers blooming in your garden?'' and ``Why don't you talk about your family?'' It is preferable to create a proposal for specific conversation content, such as "", as support information, and convey it to Caregiver Z.

It is also important to check whether the conversation and messages are being conveyed to care recipient Y. It is also important to see the replies and reactions of care recipient Y, but in the case of a person with dementia or a person who is hard of hearing, it is not easy to accurately grasp this reaction. The means for understanding this reaction will be described later.
If you judge that care recipient Y is not responding to or not communicating with your conversation or voice, say, ``Let's talk to you a little louder.'' or ``Let's talk to you using body language.'' It is preferable to create support information such as "Let's talk to care recipient Y from a position where he can see it." and convey it to caregiver Z again.
Furthermore, if it is determined that Caregiver Y has shown an unpleasant reaction to caregiver Z's voice, he or she may say, ``Raise the tone of your voice.'' or ``Talk to them with a smile.'' It is preferable to create support information such as the following and convey it to Caregiver Z again.

Next, a means for determining whether or not cared person Y is responding to caregiver Z's voice will be explained.

Many of the care recipients Y have dementia or are hard of hearing, and many of them do not respond or are unable to respond to caregivers Z's calls. At the care site, caregiver Z is required to make many calls to cared person Y, but care recipient Y often does not respond, making it difficult to grasp the effectiveness of the calls. Not being able to grasp the reaction to a call out to someone can lead to them refusing to provide care, which can lead to a decline in job satisfaction and motivation, and can even lead to employees leaving their jobs.

On the other hand, even if the caregiver does not respond or is unable to respond to caregiver Z's voice, there are cases in which the person responds to caregiver Z's voice. As one of the reactions, it is known that the cared person Y who is addressed by the caregiver Z shows a change in heart rate. If the caregiver Z is able to grasp changes in the heart rate of the cared person Y by utilizing this phenomenon, it is possible to determine whether or not the cared person Y is responding to the call.

Therefore, a configuration was adopted in which the cared person Y is fitted with a heart rate meter H, the heart rate change of the cared person Y is detected in response to a call from the carer Z, and this is transmitted to the carer Z.
With this configuration, it is possible to understand the reaction of care recipient Y to the call out, so it is possible to prevent and suppress the decline in satisfaction and motivation mentioned above, and eliminate one of the causes of turnover. This can be expected to have the effect of reducing the number of people leaving the company.

FIG. 3 is a diagram showing an example in which a heart rate meter H is attached to a cared person Y.
The heart rate meter H used here is not limited, but it is preferably a wearable type heart rate meter that can be worn on the wrist or the like. Wristwatch-type information terminals called smart watches and the like that have a function of measuring heart rate are commercially available, and these may be used.

The heart rate meter H worn by the cared person Y has a wireless communication function. For example, short-range wireless communication such as Bluetooth (registered trademark) can be mentioned. In the context of physical care, it is assumed that the heart rate monitor H worn by care recipient Y and the head-mounted wearable terminal W worn by caregiver Z are within a few meters, so it is assumed that Wireless communication is considered preferable.

By using this wireless communication function to send heart rate data to the head-mounted wearable terminal W worn by the caregiver Z, the caregiver Z can monitor the care recipient using the head-mounted wearable terminal W. It is possible to understand changes in Y's heart rate.

Examples of means for grasping heart rate changes in the head-mounted wearable terminal W include means for transmitting a specific heart rate audibly through a speaker function W2 or displaying it on a display function W3. In addition, instead of notifying the specific heart rate, means may be adopted to notify only the change in the heart rate, that is, the determination result as to whether or not there is a response to the voice call.

Note that the heart rate value and reaction determination results may be directly processed within the head-mounted wearable terminal W, or the received heart rate information may be sent once to an external computer C and then processed by this external computer C. After being processed, it may be returned to the head-mounted wearable terminal W worn by the caregiver Z as part of the support information. With the latter method, the heart rate data of cared person Y can be recorded and managed on external computer C, and the computer's advanced processing power can be used to judge whether or not there is a response to calls. You can also do it.

Next, a method for accurately understanding the contents of the meals that care recipient Y actually ingested will be explained.
In care settings such as nursing facilities, the menus are prepared for meals served to care recipient Y, taking into consideration the individual care recipient's health condition and physical condition, and ensuring that the necessary nutrients are ingested. Nutritional management is carried out in There are four types of food shapes: ``Easy to chew,'' ``Can be crushed with the gums,'' ``Can be crushed with the tongue,'' and ``No need to chew,'' and are adjusted according to the swallowing function of the care recipient.

On the other hand, even if a meal is served that provides the necessary nutrients, it is not guaranteed that the care recipient will be able to finish the meal without leaving any leftovers. If you have leftover food, you won't be able to ingest the nutrients you need, and your nutritional management cannot be said to be perfect. Furthermore, when a cared person becomes unwell for some reason, it is common to check the contents of the previous meal. Even in this case, if leftover food is not accurately known, there is a problem in that it is not possible to appropriately determine whether or not the reason for becoming unwell is due to the meal.

The present invention is a nursing care support system 1 implemented by a caregiver Z wearing a head-mounted wearable terminal W. It would be convenient if the head-mounted wearable terminal W could be used to accurately grasp the contents of the meals that the care recipient Y actually ingested.

Therefore, in the present invention, the head-mounted wearable terminal W worn by the caregiver Z is used to photograph leftover food when cleaning up a meal, and the photographed video data is sent to the external computer C. A method was adopted in which the external computer C accurately ascertained the contents of the meals actually ingested. Using the microphone function of the head-mounted wearable terminal W, the caregiver Z speaks the name of the care recipient Y and the time of provision, and records the meal contents consumed by the target care recipient Y on the external computer C. You can make it easier to understand. Even if there is no leftover food, by taking a picture of the empty tableware, it is possible to know that all the food served has been eaten.
As a result, it is possible to accurately determine whether the cared person Y is properly ingesting nutrition, and whether or not the contents of the meal are having an effect when the person Y becomes unwell. In addition, it is possible to accurately record nursing care records including the contents of meals.

Finally, the functions related to the above-mentioned conversation, calling out, or calling out will be explained.
As mentioned above, there is a significant shortage of caregivers in Japan, and the shortage is predicted to increase further in the future. One solution to this problem is to employ foreign workers as caregivers. Although these foreign workers are able to communicate in Japanese to some extent, it is difficult to choose the right words to use when addressing them in nursing care settings, and it is not easy to choose the appropriate words to address them.
Therefore, it is preferable that an automatic translation function is added to the nursing care support system 1 according to the present invention. Various tools have already been proposed for automatic translation functions, and these automatic translation functions can be employed without any particular restrictions. Among these, it is preferable to adopt a configuration in which words uttered by caregiver Z in a foreign language are translated into Japanese and automatically transcribed into speech. Moreover, it is preferable that this automatic translation function be installed in the head-mounted wearable terminal W.
As a result, even those who are not good at communicating in Japanese (particularly foreign workers) can be greeted in an optimal manner.
