[Embodiment]
[1. Introduction]
At nursing care sites, adult diapers are sometimes used for care recipients, and these adult diapers are classified into a plurality of types depending on how they are put on and taken off. For example, there are two types of diapers for adults, such as pants type and tape type.

For example, pants-type diapers are characterized by a structure that can be raised and lowered like underwear, and tape-type diapers are structured so that they can be taped so that the wearer can easily put them on and take them off even while lying down. It is characterized by

For this reason, pants-type diapers are often used mainly for care recipients who can excrete independently in the toilet. In addition, independent excretion as used herein refers to a series of excretion actions such as moving to the toilet by oneself, adding to the toilet, and cleaning up afterward. On the other hand, tape-type diapers are mainly used for care-receivers who spend most of their time sleeping and who have no choice but to rely on caregivers for excretion disposal.

Here, in the present situation, it is often the caregiver's empirical rule that the judgment as to whether to use a pants-type diaper or a tape-type diaper for the care-receiver is made. For example, the caregiver visually confirms the care recipient's walking status, and if the risk of falling is considered low, the caregiver determines that the care recipient can safely go to the toilet and relieve himself safely, that is, can go to the bathroom independently. and determine that pants-type diapers should be used. On the other hand, if the risk of falling is high, it is judged that independent excretion is difficult because there is a risk of falling on the way to the toilet or when using the toilet. of diapers should be used.

However, such judgments based on empirical rules focus on the subjectivity of the caregiver, so too much consideration is given to safety. A care recipient who is able to go to the toilet and is able to excrete on his own (for example, a care recipient who has room for improvement to become able to excrete independently in the future, depending on rehabilitation) ), there is a problem that it is judged that tape-type diapers should be used.

In addition, when a tape-type diaper is used for such a care recipient who has the ability to excrete independently, the care recipient receives more assistance in excreting from the caregiver, and as a result, the care recipient becomes independent. The opportunity to do so will be lost. If so, there is a risk that QOL (Quality of Life) will deteriorate due to a decrease in physical strength and motivation. In addition, when tape-type diapers are used, there is also the problem that the cared person's self-esteem is hurt by being taken care of by changing diapers.

Therefore, the present invention proposes an optimal adult diaper (absorbent article) according to the situation of independent excretion by using digital technology to solve the problem that the situation of independent excretion cannot be judged appropriately based on empirical rules by caregivers. I came to do it.

Specifically, according to the information processing according to the embodiment, the situation of independent excretion by the care recipient (user) is evaluated based on the analysis result regarding walking of the care recipient (user), and based on the evaluation result, Adult diapers to be proposed to the care recipient are determined. With this kind of information processing, it becomes possible to appropriately judge the situation of independent excretion by the care recipient and propose the optimal adult diaper according to the judgment result. It is thought that it will be possible to reduce the burden related to caregiving and effectively increase opportunities for improving the QOL of care recipients. Information processing according to the embodiment will be described in detail below.

[2. About system configuration]
From here. An example of an information processing system according to an embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an overview of information processing according to an embodiment. An information processing system 1 illustrated in FIG. 1 is an example of a determination system, and includes a terminal device 10 and an information processing device 100 . The terminal device 10 and the information processing device 100 are communicably connected by wire or wirelessly via a network.

The terminal device 10 is an information processing terminal used by an end user. The terminal device 10 is, for example, a smart phone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like.

In addition, an application AP (hereinafter abbreviated as “application AP”) corresponding to an analysis program, which is a program for analyzing walking of a person, is preinstalled in the terminal device 10 . Therefore, the terminal device 10 analyzes the walking of the person under the control of the application AP. For example, the terminal device 10 analyzes the gait state of the subject as to what kind of gait characteristics it has. For example, the terminal device 10 analyzes the walking of the subject based on the captured image in which the walking of the subject is captured. Also, the terminal device 10 transmits the analysis result to the information processing device 100 . In addition, the terminal device 10 displays, on the screen corresponding to the application AP, suggested information regarding absorbent articles determined by the information processing device 100 based on the analysis results.

In the following embodiment, it is assumed that information is transmitted and received between the terminal device 10 and the information processing device 100 by the application AP, which is an analysis program. Transmission and reception of information between may be performed by a general-purpose application (browser application).

The information processing device 100 is an example of a determination device, and performs information processing according to the above-described embodiments. Specifically, the information processing apparatus 100 acquires an analysis result regarding walking of the user, and evaluates the state of independent excretion by the user based on the acquired analysis result. Then, the information processing device 100 determines the absorbent article to be proposed to the user based on the evaluation result.

[3. About an example of information processing]
From here on, an example of the overall flow of the proposal processing according to the embodiment will be described with reference to FIG. 1 . The example of FIG. 1 shows a scene in which walking analysis and information proposal based on the analysis results are performed for a care recipient U1 who is a user receiving care from a caregiver HP1 in a nursing care facility FC1. Moreover, the terminal device 10 shown in FIG. 1 is a smart phone used by caregiver HP1, and assumes that application AP is installed.

In the example of FIG. 1, first, the caregiver HP1 uses the terminal device 10 to shoot a moving image of the cared person U1 walking (step S11). For example, the caregiver HP1 may take an image of the cared person U1 walking from any direction. For example, the caregiver HP1 takes a picture of the cared person U1 walking in a particular direction from the front of the cared person U1, the side of the cared person U1, or the back of the cared person U1.

Further, in step S11, the terminal device 10 acquires a captured moving image by capturing an image of the cared person U1 according to the moving image capturing of the caregiver HP1.

Next, the terminal device 10 performs a gait analysis for analyzing the gait state of the cared person U1 based on the captured moving image (step S12). For example, the terminal device 10 calculates items for comprehensively evaluating walking (for example, walking speed, stride length, walking rate, and foot pressure) and items for evaluating the stability of walking (head sway, trunk sway, leg sway), and items for evaluating left-right differences (head tilt left-right difference, trunk tilt left-right difference).

In addition, the terminal device 10 transmits the analysis result of the gait analysis to the information processing device 100 (step S13). Then, the information processing device 100 acquires the analysis result (step S14). Specifically, the information processing device 100 acquires the analysis result of the gait analysis of the terminal device 10 from the terminal device 10 .

The information processing apparatus 100 also estimates the risk of falling when the care recipient U1 excretes independently based on the walking state indicated by the analysis result (step S15). For example, the information processing apparatus 100 determines the walking state indicated by the analysis result based on an item for comprehensively evaluating walking, an item for evaluating stability regarding walking, and an item for evaluating left-right difference. estimate the risk of falling when putting on and taking off adult diapers by themselves. Note that the fall risk here may be a score that indicates the possibility of falling.

Next, the information processing device 100 evaluates the independent excretion status of the care recipient U1 based on the fall risk (step S16). For example, the information processing device 100 may calculate an evaluation value indicating the state of independent excretion by the care recipient U1 based on the fall risk, or may evaluate the state of independent excretion by the care recipient U1 by rank. good too. When calculating the evaluation value, the information processing apparatus 100 can calculate a higher evaluation value as the fall risk is lower, from the viewpoint that the possibility of independent excretion is higher as the fall risk is lower.

For example, if the information processing apparatus 100 estimates a fall risk of "10" (probability of falling of 10%) in step S14, the information processing apparatus 100 can calculate an evaluation value of "90" based on the fall risk of "10".

Next, information processing apparatus 100 determines an adult diaper to be proposed to care recipient U1 based on the evaluation result (step S17). For example, based on whether the evaluation result satisfies a predetermined condition, the information processing apparatus 100 selects which of the two type types, such as the pants type and the tape type, is the type corresponding to the cared person U1. Presume there is. For example, the information processing apparatus 100 estimates that the underpants type is the form type corresponding to the cared person U1 when it can be determined that the person can excrete independently because the evaluation value is higher than a predetermined threshold. On the other hand, the information processing apparatus 100 estimates that the tape type is the form type corresponding to the cared person U1 when it can be determined that the independent excretion is impossible because the evaluation value is lower than the predetermined threshold. Then, the information processing apparatus 100 determines the adult diaper of the estimated form type among the adult diapers of the proposal candidates as the adult diaper to be proposed to the care-receiver U1. For example, the information processing apparatus 100 compares the product information storage unit 123 ( FIG. 5 ) in which product information indicating adult diapers as proposal candidates is stored with the estimation result, thereby determining the adult diapers to be proposed to the care-receiver U1. Determine which product the diaper is.

In the example of FIG. 1, the information processing apparatus 100 proposes pants-type adult diapers to the cared person U1 in response to estimating that the form type according to the cared person U1 is the pants type. It is judged as a diaper.

Then, the information processing apparatus 100 proposes the adult diaper indicated by the determination result as a product to be worn by the cared person U1 (step S18). For example, the information processing apparatus 100 generates proposal content that proposes an adult diaper indicated by the determination result as a product to be worn, and transmits this to the terminal device 10 . In the example of FIG. 1 , the information processing apparatus 100 generates the suggested content C1, which is a screen in which the adult diaper indicated by the determination result is suggested as a product to be worn, and transmits the suggested content C1 to the terminal device 10. shown.

According to the example of FIG. 1, the product information PD1 corresponding to the adult diaper indicated by the determination result is displayed in the suggested content C1. Further, as shown in FIG. 1, the product information PD1 may consist of a text indicating that the adult diaper indicated by the determination result is a pants type, and a package image of this adult diaper. Link information (URL) for transitioning to the detailed screen of the product indicated by the product information PD1 may be attached to the suggested content C1.

An example of information processing according to an embodiment performed by the information processing apparatus 100 has been described above using FIG. According to such an information processing device 100, it is possible to appropriately judge the situation of independent excretion by the care recipient U1, and to propose the optimal adult diaper according to the judgment result. This reduces the burden of nursing care work for the care receiver, and effectively increases the chances of improving the QOL of the care recipient U1.

In the example of FIG. 1, the terminal device 10 performs gait analysis under the control of the application AP, but the gait analysis may be performed on the information processing device 100 side. In such a case, the information processing apparatus 100 may be configured to acquire captured moving images from the terminal device 10, for example, in a state in which an analysis program for analyzing the walking of the user is installed.

[4. Configuration of Information Processing Device]
Next, the information processing apparatus 100 according to the embodiment will be described using FIG. FIG. 2 is a diagram illustrating a configuration example of the information processing apparatus 100 according to the embodiment.

(Regarding Analysis Result Storage Unit 121)
The analysis result storage unit 121 stores an analysis result regarding walking of a user (for example, a user in the position of a care recipient). Here, FIG. 3 shows an example of the analysis result storage unit 121 according to the embodiment. In the example of FIG. 3, the analysis result storage unit 121 has items such as "user ID", "comprehensive evaluation", "stability", "lateral difference", and "fall risk".

"User ID" indicates identification information for identifying a user. For example, "user ID" indicates identification information that identifies a user who is in the position of a care receiver.

"Comprehensive evaluation" is an example of the walking state indicated by the analysis result, and corresponds to an item for comprehensively evaluating walking. Further, as shown in FIG. 3, the "comprehensive evaluation" may be composed of items indicating detailed walking conditions such as "walking speed", "step length", and "gait rate".

"Stability" is an example of the walking state indicated by the analysis result, and corresponds to an item for evaluating the stability of walking. Further, as shown in FIG. 3, "stability" may be composed of items indicating detailed walking conditions such as "head shaking", "trunk shaking", and "leg shaking".

“Left-right difference” is an example of the walking state indicated by the analysis result, and corresponds to an item for evaluating the left-right difference in walking. Moreover, as shown in FIG. 3, the "left-right difference" includes "left-right difference in head tilt", "left-right difference in trunk tilt", "left-right difference in pelvis tilt", and "left-right difference in elbow movement tilt". It may be composed of items indicating detailed walking conditions such as left-right difference and left-right difference in pitch.

"Risk of falling" indicates the risk of falling when the user excretes independently. For example, "fall risk" indicates the risk of falling when the user puts on and takes off the adult diaper by himself/herself.

That is, in the example of FIG. 3, the walking analysis of the user (care receiver U1) identified by the user ID "U1" shows that the walking condition of the care receiver U1 is "walking speed #1", "stride length # 1”, “gait rate #1”, “head sway #1”, “trunk sway #1”, “leg sway #1”, “head tilt difference #1”, “trunk An example is shown in which a left-right difference in tilt #1, a left-right difference in pelvis tilt #1, a left-right difference in elbow movement tilt #1, and a left-right difference in pitch #1 are calculated. In the example of FIG. 3, the walking state indicated by the analysis result is conceptually represented using symbols such as "walking speed #1", but in reality, valid information indicating the analysis result is stored. be done.

Also, the example of FIG. 3 shows an example in which the fall risk of care recipient U1 is estimated to be "fall risk #1" based on the analysis results indicated by the associated items. As for the "fall risk" as well, in practice, valid information is stored instead of the conceptual notation as shown in FIG.

(Regarding physical information storage unit 122)
The physical information storage unit 122 stores physical information of a user (for example, a user in the position of a care recipient). Here, FIG. 4 shows an example of the physical information storage unit 122 according to the embodiment. In the example of FIG. 4, the physical information storage unit 122 has items such as "user ID", "physical information", and "difficulty in putting on and taking off". Further, as shown in FIG. 4, examples of "physical information" include "motion information", "range of motion information", "posture information", and "muscle strength information".

"User ID" indicates identification information for identifying a user. For example, "user ID" indicates identification information that identifies a user who is in the position of a care recipient.

“Movement information” is information indicating how well a predetermined motion required when putting on and taking off an adult diaper can be performed. In addition, the predetermined motion here means, for example, a motion to stand up from a sitting state, a motion to sit down from a standing state, a motion of an arm when pulling up an adult diaper, a motion of an arm when lowering an adult diaper, and the like. be. Further, the "movement information" may be an analysis result obtained by analyzing based on an actually captured moving image as to how much of the predetermined movement required when putting on and taking off an adult diaper can be performed. May be registered by a caregiver.

"Range of motion information" is information indicating the range of motion of the user's hip joint or trunk. "Range of motion information" includes, for example, the user's main joints (for example, lower limb joints such as hip joints, knee joints, hip joints, ankle joints, trunk joints such as thoracolumbar joints from the waist to the back, arms, shoulders, etc.). , upper limb joints such as elbows) may be information indicating an estimation result of estimating the range of motion. Also, the “range of motion information” may be estimation results obtained by estimating the range of motion of the hip joint, the range of forward bending of the trunk, and the range of motion of turning the trunk. Also, these ranges of motion may be estimated based on a captured moving image showing how the user moves, or may be registered by a caregiver, for example.

“Posture information” is information indicating the posture of the user. The “posture information” may be, for example, an analysis result obtained by analyzing the state of the user's posture based on a captured moving image showing how the user moves, or may be registered by a caregiver.

“Strength information” is information indicating the muscle strength of the user. The "muscle strength information" may be, for example, information indicating the results of a grip strength test, or may be the results of a survey conducted to determine whether or not an adult diaper can be broken by oneself.

The "difficulty level of putting on and taking off" is information indicating the difficulty level of putting on and taking off the absorbent article by the user himself/herself. The "difficulty in putting on and taking off" is estimated based on the "physical information". For example, the "difficulty level of putting on and taking off" may be estimated based on all or a combination of "motion information", "range of motion information", "posture information", and "strength information".

That is, in the example of FIG. 4, the "physical information" of the user (care recipient U1) identified by the user ID "U1" includes "motion information #1", "range of motion information #1", and "posture information #1". An example of "information #1" and "strength information #1" is shown. In the example of FIG. 4, the physical information is conceptually represented using symbols such as "motion information #1", but in reality, valid information indicating the physical information is stored.

In addition, the example of FIG. 4 shows an example in which the difficulty level of putting on and taking off caregiver U1 is estimated to be "difficulty level of putting on and taking off #1". As for the "difficulty level of attachment/detachment", not a conceptual representation such as 4, but valid information is actually stored.

(Regarding product information storage unit 123)
The product information storage unit 123 stores information on absorbent articles sold as products. Here, FIG. 5 shows an example of the product information storage unit 123 according to the embodiment. In the example of FIG. 5, the product information storage unit 123 has items such as "evaluation result", "form type", "size", "time period", "absorption performance", and "product information".

"Evaluation result" indicates information corresponding to the evaluation result of the user's independent excretion status. The "form type" indicates the type in which the form of the adult diaper is classified according to the putting on and taking off method. "Size" is information indicating the size of an adult diaper. Further, the "type type" is to be determined according to the corresponding "evaluation result", and for example, there are pants type and tape type. Note that the "form type" is not limited to the pants type and the tape type, and there is, for example, a two-way type that has both the features of the pants type and the tape type. In this embodiment, the 2Way type belongs to the underpants type.

"Time zone" is information that defines whether the product is for daytime use or nighttime use. "Absorptive performance" is information that defines how much urine-absorbing performance (capacity) a product has. "Product information" indicates product information relating to absorbent articles. Note that the absorbent article indicated by the "product information" may be an adult diaper or an incontinence pad. Also, the absorbent article indicated by the "product information" may be a combination of an adult diaper and an incontinence pad to be used together with the adult diaper.

That is, in the example of FIG. 5, the information processing apparatus 100 evaluates the user's independent excretion status, and if it can be evaluated as "A judgment" (for example, independent excretion possible), the information processing apparatus 100 responds to this user. An example of estimating that the form type is "pants type" is shown.

In the example of FIG. 5, the "pants type" absorbent article is further classified by "size type" such as "S size", "M size", and "L size". An example is shown in which absorbent articles belonging to the "pants type" can be narrowed down to absorbent articles of a size type according to the body shape of the user.

In addition, in the example of FIG. 5 , the “pants type” and “S size” absorbent articles are further classified according to the “time zone” for each use, such as “day use” and “night use”. shows an example that can be further narrowed down from among "pants type" and "S size" absorbent articles according to convenience such as what time period the absorbent article is to be worn.

In addition, in the example of FIG. 5, the "pants type", "S size" and "daytime" absorbent articles "have an absorbent body capable of absorbing two times of urination" and "have an absorbent body capable of absorbing four times of urination". The information processing apparatus 100 is further classified by "absorption performance" such as "has an absorbent body", etc., and the information processing apparatus 100 selects from among "pants type", "S size", and "daytime" absorbent articles according to the excretion situation of the user. An example of narrowing down absorbent articles having a corresponding absorption performance will be shown.

In addition, in the example of FIG. 5, the absorbent article of "pants type", "S size" and "daytime" and "having an absorbent body capable of absorbing two times of urination" has product information "PD1-SD2". Here is an example that is a product denoted by .

(Regarding the control unit 130)
Returning to FIG. 2, the control unit 130 executes various programs stored in a storage device inside the information processing apparatus 100 using a RAM as a work area by a CPU (Central Processing Unit), MPU (Micro Processing Unit), or the like. It is realized by Also, the control unit 130 is implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 2, the control unit 130 has an acquisition unit 131, an evaluation unit 132, an estimation unit 133, a determination unit 134, a proposal unit 135, and a state estimation unit 136, which will be described below. Realize or perform an information processing function or action. Note that the internal configuration of the control unit 130 is not limited to the configuration shown in FIG. 2, and may be another configuration as long as it performs the information processing described later. Moreover, the connection relationship between the processing units of the control unit 130 is not limited to the connection relationship shown in FIG. 2, and may be another connection relationship.

(Regarding the acquisition unit 131)
The acquisition unit 131 acquires an analysis result regarding walking of the user. For example, the acquisition unit 131 acquires an analysis result indicating the walking state of the user as the analysis result. For example, the acquisition unit 131 acquires, as the analysis result indicating the user's walking state, an analysis result obtained by analyzing the user's walking state based on a captured image in which the user's walking state is captured.

In the example of FIG. 1, the terminal device 10 analyzes the captured moving image showing the user's walking in accordance with the control of the application AP corresponding to the analysis program for analyzing the user's walking. Analyzing the situation. Therefore, in the example of FIG. 1, the acquisition unit 131 acquires the analysis result of the gait analysis performed on the captured video by the terminal device 10 under the control of the application AP.

Further, the analysis results acquired by the acquisition unit 131 include, for example, items for comprehensively evaluating walking (for example, walking speed, stride length, and walking rate), items for evaluating stability related to walking (head shaking, trunk sway, foot sway), items for evaluating left-right difference (for example, left-right difference in head tilt, left-right difference in trunk tilt, etc.), and such analysis results are stored in the analysis result storage unit 121 store in

Further, the acquisition unit 131 may acquire an analysis result indicating the distribution of foot pressure when the user walks as the analysis result indicating the walking state of the user.

In addition, the acquisition unit 131 may further acquire physical information indicating the physical condition of the user. For example, the acquiring unit 131 acquires, as physical information, physical information indicating a predetermined action required when putting on and taking off an absorbent article. As an example, the acquisition unit 131 can perform predetermined actions required when putting on and taking off an absorbent article (for example, actions to stand up from a sitting state, actions to sit down from a standing state, actions of arms when pulling up an adult diaper, Acquisition of information indicating an analysis result of how much the user can perform an arm movement when putting down an adult diaper.

The acquisition unit 131 may also acquire information indicating the posture of the user or information indicating muscle strength as the physical information. Furthermore, the acquisition unit 131 may also acquire information indicating the range of motion of the user's hip joints or trunk.

Acquisition unit 131 also stores the acquired physical information in physical information storage unit 122 .

(Regarding the evaluation unit 132)
The evaluation unit 132 evaluates the state of independent excretion by the user based on the analysis result acquired by the acquisition unit 131 . For example, the evaluation unit 132 evaluates the state of independent excretion by the user based on the walking state indicated by the analysis result acquired by the acquisition unit 131 .

In addition, the evaluation unit 132 estimates the fall risk when the user excretes independently from the analysis result acquired by the acquisition unit 131, and evaluates the user's independent excretion status based on the estimated fall risk. In this regard, according to the example of FIG. 1, the evaluation unit 132 evaluates the user based on an item for comprehensively evaluating walking, an item for evaluating stability related to walking, and an item for evaluating left-right difference. A fall risk is estimated when a cared person U1 puts on and takes off an adult diaper by himself/herself. Then, the evaluation unit 132 evaluates the independent excretion status of the care recipient U1 based on the estimated fall risk. For example, the evaluation unit 132 calculates an evaluation value indicating the independent excretion status of the care receiver U1 based on the fall risk.

In addition, the evaluation unit 132 may evaluate the user's independent excretion status based on the analysis result and physical information acquired by the acquisition unit 131 . For example, the evaluation unit 132 estimates the difficulty level of putting on and taking off the absorbent article based on the physical information, and compares the estimated difficulty level of putting on and taking off the absorbent article with the fall risk estimated from the analysis result. Based on this, the status of independent defecation by users will be evaluated. For example, the evaluation unit 132 determines whether it is difficult to put on and take off based on all or any combination of “motion information”, “range of motion information”, “posture information”, and “muscle strength information” stored in the physical information storage unit 122 . Estimate degrees. As an example, based on these body information, the evaluation unit 132 determines a predetermined motion (for example, a motion to stand up from a sitting state, a motion to sit down from a standing state, an adult diaper motion, etc.) required when putting on and taking off an absorbent article. arm movement when pulling up the diaper, arm movement when lowering an adult diaper, etc.). Then, the evaluation unit 132 estimates the attachment/detachment difficulty level based on the analysis result. For example, the evaluation unit 132 estimates a lower degree of difficulty in putting on and taking off the absorbent article as it is determined that a predetermined action required for putting on and taking off the absorbent article can be performed more smoothly based on the analysis result. For example, the information processing apparatus 100 may have a storage unit that predefines what kind of analysis results are obtained and what level of attachment/detachment difficulty is estimated. In this case, the evaluation unit 132 The attachment/detachment difficulty can be estimated by comparing this storage unit with the actual analysis result.

(Regarding the estimation unit 133)
The estimation unit 133 estimates the type of absorbent article according to the user based on the evaluation result by the evaluation unit 132 . As described above, adult diapers, which are absorbent articles, are classified into at least two types, the pants type and the tape type, depending on how they are put on and taken off. Therefore, the estimating unit 133 estimates which of the two morphological types is the morphological type according to the user, based on whether or not the evaluation result satisfies a predetermined condition.

According to the example of FIG. 1, if the estimation unit 133 can determine that the evaluation value indicated by the evaluation result is higher than the predetermined threshold value and the independent excretion is possible, the pants type is the form type corresponding to the cared person U1. We estimate that On the other hand, the estimating unit 133 estimates that the tape type is the morphology type corresponding to the care recipient U1 when it can be determined that independent excretion is impossible because the evaluation value indicated by the evaluation result is lower than the predetermined threshold.

Note that, when a plurality of detailed types are associated with the estimated type, the estimation unit 133 further estimates the detailed type according to the user among the plurality of detailed types using the evaluation result. You may For example, when a plurality of detailed types are associated with the estimated form type, the estimating unit 133 further estimates a detailed type according to the user among the plurality of detailed types based on the evaluation result. do. Regarding this point, for example, assuming that the estimating unit 133 estimates that the form type corresponding to the care receiver U1 is the pants type, when the pants type adult diapers are classified into a plurality of types according to the operability, , based on the evaluation result, it is estimated which of the plurality of detailed types is the detailed type according to the user.

(Regarding the determination unit 134)
The determination unit 134 determines the absorbent article to be proposed to the user based on the evaluation result by the evaluation unit 132 . More specifically, the determination unit 134 determines the absorbent article of the type estimated by the estimation unit 133 based on the evaluation result among the proposal candidate absorbent articles as the absorbent article to be proposed to the user.

According to the example of FIG. 1, the determination unit 134 compares the estimated result with the product information storage unit 123 (FIG. 5), which stores product information indicating adult diapers as proposal candidates, to determine whether the care-receiver Determine which adult diaper product is proposed to U1.

(Regarding the proposal section 135)
The proposal unit 135 makes various proposals regarding the user. Specifically, the proposal unit 135 makes proposals regarding absorbent articles.

For example, the proposal unit 135 proposes the absorbent article determined by the determination unit 134 as a product to be worn by the user. According to the example of FIG. 1 , the proposal unit 135 generates proposal content in which the adult diaper indicated by the determination result is proposed as a product to be worn, and transmits this to the terminal device 10 .

In addition, the proposing section 135 may further propose the method of attaching and detaching the absorbent article determined by the determining section 134 . For example, the proposal unit 135 proposes a method of putting on and taking off according to the nursing care skill of the caregiver in charge of replacing the absorbent article determined by the determination unit 134 . For example, if the determination unit 134 determines that the nursing care skill of the caregiver who is in charge of exchanging absorbent articles is less than a predetermined value and, for example, that the caregiver has little experience in assisting, the proposal unit 135 performs detailed attachment/detachment. The method is transmitted to the terminal device 10 of this caregiver. On the other hand, when it is determined by the determination unit 134 that the nursing care skill of the caregiver in charge of exchanging the absorbent article is equal to or higher than a predetermined value and, for example, the caregiver's experience is sufficient, the proposal unit 135 selects a simple attachment/detachment method. is transmitted to the terminal device 10 of the caregiver, or no method of attachment/detachment is proposed.

According to such a proposed method, the information processing apparatus 100 can reduce the burden of nursing care work by appropriately supporting the caregiver. In addition, since the information processing apparatus 100 can change the method of proposing the attachment/detachment method according to the nursing care skill of the caregiver, it is possible to appropriately support the caregiver who does not have sufficient nursing care skill. For caregivers who have sufficient capacity, it is possible to make proposals that give priority to the caregiver's way of doing things.

Note that the proposing unit 135 can adopt any method for proposing the attachment/detachment method. For example, the proposal unit 135 can display content indicating how to put on and take off the absorbent article in a state of being superimposed on a predetermined object related to the absorbent article. For example, when a photographed image of an absorbent article is acquired from the terminal device 10, the proposing unit 135 indicates how to put on and take off the absorbent article in the photographed image displayed on the screen of the terminal device 10. Control so that the content is superimposed and displayed.

The proposal unit 135 may also propose a method of attaching an incontinence pad to an adult diaper as a proposal regarding absorbent articles.

In addition, the proposal unit 135 may propose a guide method for guiding the user to the toilet based on the user's independent excretion situation estimated based on the evaluation result by the evaluation unit 132 . For example, the proposing unit 135 proposes, as a guidance method, a method of calling, such as what to call the user when guiding the user to the toilet and what tone to call to. As an example, the proposing unit 135 can suggest a method of greeting such as "Let's make eye contact and speak with a smile." In addition, the proposal unit 135 may change the method of suggesting the guidance method according to the nursing care skill of the caregiver, similarly to the proposal of the attachment/detachment method.

According to such a proposed method, the information processing apparatus 100 can reduce the burden of nursing care work by appropriately supporting the caregiver. In addition, since the information processing apparatus 100 can change the method of proposing the attachment/detachment method according to the nursing care skill of the caregiver, it is possible to appropriately support the caregiver who does not have sufficient nursing care skill. For caregivers who have sufficient capacity, it is possible to make proposals that give priority to the caregiver's way of doing things.

In addition, the proposal unit 135 may not only propose the attachment/detachment method and the guidance method, but also provide information that increases the motivation of the caregiver for nursing care work. For example, the proposal unit 135 controls the output of the caregiver's terminal device 10 to output "Let's do our best!" Further, for example, when detecting that various nursing care tasks have ended, the proposing unit 135 controls the terminal device 10 of the caregiver to output "Thank you for your hard work." Note that such output control may be performed by a processing unit (for example, a providing unit) other than the proposal unit 135 (not shown).

(Regarding the state estimation unit 136)
The state estimation unit 136 estimates changes in the state of the user based on the analysis result acquired by the acquisition unit 131 . The proposing unit 135 then proposes information according to the estimation result by the state estimating unit 136 .

For example, the state estimating unit 136 compares the current analysis result of the user's walking analysis with the past analysis result of the user's walking analysis as the analysis result. Estimate the improvement status of the walking condition of the person. For example, the state estimating unit 136 compares the current analysis result with the past analysis result of the user's walking analyzed in the past to determine whether the user's walking state has improved. do. When the state estimating unit 136 determines that the walking state is improving, the state estimating unit 136 estimates the degree of improvement as the state of improvement. On the other hand, when the state estimating unit 136 determines that the walking state has not improved (that is, has deteriorated), it estimates the degree of deterioration as the state of improvement.

In this case, the proposing unit 135 presents the improvement state, and when it is determined that the walking state of the user is deteriorating from the improvement state, proposes a nursing care method capable of improving the walking state. According to such an information processing apparatus 100, since it is possible to visualize the improvement state to the user, it is possible to increase motivation to further improve when the walking state is improved. If it is getting worse, we can help you improve your walking.

Moreover, the proposal part 135 may make a proposal based on the improvement status of other nursing care facilities. For example, it is assumed that a care recipient U11 whose attributes are similar to the care recipient U1 who resides in the care facility FC1 resides in another care facility FC11. In this case, the state estimating unit 136 compares the improvement state of the walking state of the care receiver U1 and the improvement state of the walking state of the care receiver U11, and estimates which is improved by how much. .

In that case, the proposal department 135 will tell the nursing facility FC1 side, "Mr. A of the nursing facility FC11 has improved by XX in the last half year. Mr. B has lost by XX minutes. Let's go!" is output. On the other hand, the proposal unit 135 outputs to the nursing facility FC11 side a proposal content such as "I won by XX minutes more than Mr. B in the nursing facility FC1! Let's try harder to win next time."

According to such an information processing apparatus 100, for example, since it is possible to realize a competition for improvement status between nursing care facilities, it is possible to effectively increase the motivation of the user to work on rehabilitation. become.

In addition, the state estimating unit 136 determines whether the user will be in a predetermined physical state in the future based on predetermined statistical data related to other users for whom analysis results similar to the analysis results obtained by the obtaining unit have been obtained. Risk may be estimated. For example, the state estimating unit 136 acquires statistical data based on care-related information about other users for whom analysis results similar to those of the care receiver U1 have been obtained. Here, it is assumed that the state estimation unit 136 has obtained statistics that other users for whom similar analysis results have been obtained will be bedridden after several years. In this case, the condition estimation unit 136 estimates the risk that the care recipient U1 will also become bedridden in the future based on such statistical data.

Moreover, when it is estimated that the care recipient U1 will become bedridden in the future based on the estimated risk, the proposal unit 135 proposes a care method capable of reducing the risk. According to such an information processing apparatus 100, since future risks can be visualized, countermeasures can be taken in advance so as to reduce the risk of becoming bedridden.

[5. Processing procedure]
Next, the procedure of information processing according to the embodiment will be described with reference to FIG. FIG. 6 is a flow chart showing an information processing procedure according to the embodiment. In the example of FIG. 6, it is assumed that the terminal device 10 analyzes the walking of the cared person based on the captured moving image showing how the cared person walks under the control of the application AP. Also, in the example of FIG. 6, the absorbent article will be described as an adult diaper.

In such a case, the acquisition unit 131 determines whether or not the result of analyzing the walking state of the care-receiver's walking characteristics has been acquired (step S101). While the acquisition unit 131 determines that the analysis result has not been acquired (Step S101; No), it waits until it can determine that the analysis result has been acquired.

On the other hand, when it is determined that the analysis result has been obtained (step S101; Yes), the obtaining unit 131 further obtains physical information indicating the physical condition of the care-receiver (step S102).

Next, the evaluation unit 132 estimates the fall risk when the cared person excretes independently based on the walking state indicated by the acquired analysis result (step S103). For example, the evaluation unit 132 determines whether the care-receiver is an adult based on an item for comprehensively evaluating walking, an item for evaluating stability related to walking, and an item for evaluating left-right difference as the walking state indicated by the analysis result. Estimate the fall risk when putting on and taking off diapers by yourself.

In addition, the evaluation unit 132 estimates the degree of difficulty in putting on and taking off the adult diaper, which is the degree of difficulty for the care recipient to put on and take off the adult diaper by himself/herself, based on the physical information (step S104). For example, the evaluation unit 132 determines whether it is difficult to put on and take off based on all or any combination of “motion information”, “range of motion information”, “posture information”, and “muscle strength information” stored in the physical information storage unit 122 . Estimate degrees.

Then, the evaluation unit 132 evaluates the situation of the cared person's independent excretion based on the estimated fall risk and the degree of difficulty in putting on and taking off (step S105). For example, the evaluation unit 132, based on whether the estimated fall risk satisfies a predetermined condition and whether the attachment/detachment difficulty satisfies a predetermined condition, from the viewpoint of both the fall risk and the attachment/detachment difficulty, Comprehensive evaluation of independent defecation status.

Next, the estimating unit 133 estimates the type of adult diaper (pants type, tape type) according to the cared person based on the evaluation result of the evaluating unit 132 (step S106).

The determination unit 134 determines the absorbent article to be proposed to the care-receiver based on the estimation result of the estimation unit 133 (step S107). For example, the determination unit 134 determines, among the adult diapers as proposal candidates, the adult diaper of the form type estimated by the estimation unit 133 based on the evaluation result as the absorbent article to be proposed to the care-receiver.

Finally, the proposal unit 135 proposes the adult diaper determined by the determination unit 134 as a product to be worn by the care-receiver (step S108).

[6. Evaluation method]
Next, the evaluation method performed in step S105 of FIG. 6 will be described with reference to FIG. FIG. 7 is a diagram showing an example of an evaluation method for evaluating the state of independent excretion based on the risk of falling and the degree of difficulty in putting on and taking off.

First, the evaluation unit 132 determines whether the fall risk estimated based on the walking state indicated by the analysis result satisfies a predetermined condition. According to the example of FIG. 7, the evaluation unit 132 determines whether the fall risk is higher or lower than the predetermined threshold value N1 (step S201). The determination process in step S201 determines whether or not the care-receiver satisfies one condition (hereinafter referred to as "condition CD1") required for independent excretion, i.e., being able to safely go to the toilet and relieve oneself. for the purpose of judging.

For example, when the evaluation unit 132 determines that the risk of falling is lower than the predetermined threshold value N1 (step S201; Yes), it first determines that the care-receiver satisfies the condition CD1, which is one condition required for independent excretion. Then, it is determined whether or not the degree of difficulty in attaching/detaching estimated based on the physical information satisfies a predetermined condition. According to the example of FIG. 7, the evaluation unit 132 determines whether the attachment/detachment difficulty level is higher or lower than the predetermined threshold value N2 (step S202a). The determination process in step S202a is performed when the care-receiver reaches the toilet, sits on the toilet seat, stands up from the seated position, or puts on and takes off the adult diaper, such as putting on and taking off the adult diaper. This is done for the purpose of judging whether or not the cared person satisfies one condition required for independent excretion (hereinafter referred to as "condition CD2") that the person has the ability to perform the movement by himself/herself.

For example, when the evaluation unit 132 determines that the degree of difficulty in putting on and taking off is lower than the predetermined threshold value N2 (Step S202a; Yes), the condition CD2, which is one of the conditions required for the cared person to excrete independently, is satisfied. I judge.

In addition, it is thought that the cared person determined to satisfy both the conditions CD1 and CD2 in this way can perform a series of excretion actions, such as moving to the toilet by himself, adding to the toilet and cleaning up. be done. Therefore, the evaluation unit 132 makes a determination of "evaluation A" indicating that the cared person who satisfies both the conditions CD1 and CD2 can excrete independently. Further, the estimation unit 133 compares the evaluation result “evaluation A” with the product information storage unit 123, and estimates that the form type corresponding to the care-receiver of the “evaluation A” is the pants type.

Next, as another example, the evaluation unit 132 determines that the fall risk is lower than the predetermined threshold value N1 (step S201; Yes), and determines that the attachment/detachment difficulty level is higher than the predetermined threshold value N2 (step S202a). ; No). This example means that the condition CD1 is satisfied but the condition CD2 is not satisfied. It is considered that there is anxiety about performing the movement by oneself. Nonetheless, if the patient has the ability to move to the toilet by himself, depending on rehabilitation, it is suggested that the movement in the toilet after moving may be improved. Therefore, the evaluation unit 132 makes a determination of "evaluation B" indicating that the care-receiver who satisfies the condition CD1 but does not satisfy the condition CD2 is capable of quasi-independent excretion. Also, the estimation unit 133 compares the evaluation result “evaluation B” with the product information storage unit 123, and estimates that the form type corresponding to the care-receiver of “evaluation B” is the pants type.

For example, if the caregiver determines that the condition CD1 is satisfied but the condition CD2 is not satisfied according to his or her own empirical rule, there is a high possibility that the caregiver will try to use tape-type adult diapers in consideration of safety. However, according to the evaluation method of FIG. 6, it is possible to determine with high accuracy whether there is room for improvement so that independent excretion is possible in the future, so there is still room for improvement. It is possible to appropriately identify a care recipient who is capable of quasi-independent excretion, and prevent loss of an opportunity to act on one's own due to dependence on the caregiver.

As yet another example, the evaluation unit 132 determines that the fall risk is higher than the predetermined threshold value N1 (step S201; No), and determines that the attachment/detachment difficulty level is lower than the predetermined threshold value N2 (step S202a; Yes ). This example means that the condition CD1 is not satisfied but the condition CD2 is satisfied. It is thought that it is possible to perform actions in the toilet by oneself. In other words, it is suggested that even with assistance, the patient has the ability to perform the rest of the movement by himself as long as he goes to the toilet, and depending on rehabilitation, it may be possible to move to the toilet by himself. Therefore, the evaluation unit 132 makes a determination of “evaluation B” indicating that the care-receiver who does not satisfy the condition CD1 but satisfies the condition CD2 is capable of quasi-independent excretion. Also, the estimation unit 133 compares the evaluation result “evaluation B” with the product information storage unit 123, and estimates that the form type corresponding to the care-receiver of “evaluation B” is the pants type.

For example, if the caregiver determines that condition CD1 is not satisfied but condition CD2 is satisfied according to his or her own empirical rule, there is a high possibility that the caregiver will try to use tape-type adult diapers in consideration of safety. However, according to the evaluation method of FIG. 6, it is possible to determine with high accuracy whether there is room for improvement so that independent excretion is possible in the future, so there is still room for improvement. It is possible to appropriately identify a care recipient who is capable of quasi-independent excretion, and prevent loss of an opportunity to act on one's own due to dependence on the caregiver.

As yet another example, the evaluation unit 132 determines that the fall risk is higher than the predetermined threshold value N1 (step S201; No), and determines that the attachment/detachment difficulty level is higher than the predetermined threshold value N2 (step S202a; No ). Such an example means that both the condition CD1 and the condition CD2 are not satisfied, and the cared person judged in this way often spends the whole day sleeping and is considered to be unable to excrete independently. Therefore, the evaluation unit 132 makes a determination of "evaluation C" indicating that the cared person who does not satisfy both the conditions CD1 and CD2 cannot excrete independently. Further, the estimation unit 133 compares the evaluation result “Evaluation C” with the product information storage unit 123, and estimates that the form type corresponding to the care-receiver of “Evaluation C” is the tape type.
