Description

The present invention relates to an assessment support system technology.

Conventionally, techniques related to solutions (assessments) after grasping problems in long-term care have been publicly known. For example, as described in Patent Document 1.

Patent Document 1 describes a sheet used for planning a method for solving a problem in long-term care. The above sheet is provided with a description column for reflecting the subjective intention of the care recipient.

However, when the sheet described in Patent Document 1 is used, the caregiver will devise a method for solving the problem based on the self-reported contents of the care recipient. From this, it is conceivable that even if the description content is inaccurate or the same description content is viewed, the method of solving the problem and the response based on the difference may occur due to the difference in the caregiver's experience. This may reduce the satisfaction level of the long-term care service.

A block diagram schematically showing an assessment support system. A flowchart showing the assessment support process.

Hereinafter, the assessment support system 1 according to the embodiment of the present invention will be described. First, the room 2 of the care recipient to which the assessment support system 1 shown in FIG. 1 is applied will be described.

Room 2 is a space where the care recipient lives. In the room 2, a bed 3 for the care recipient to sleep is installed. An appropriate mattress is laid on the bed 3. The room 2 may be a room in a long-term care facility or a room in a hospital. It may also be the home room of the care recipient. Further, the lighting 4 is installed in the room 2. In the illustrated example, the lighting 4 is provided on the ceiling of the room 2. Further, the room 2 is provided with a window capable of daylighting and a curtain capable of adjusting the amount of daylighting from the window.

The assessment support system 1 shown in FIGS. 1 and 2 presents an example of a solution (assessment) after grasping the problems in the care of the care recipient. Examples of assessments (assessment examples) include tips on how to respond and prepare based on the needs of the care recipient, life issues, and precautions in caregiving. The caregiver can provide care and create a care plan by referring to the presented assessment examples. The assessment support system 1 includes a vital information sensor 10, an environmental information sensor 20, a control device 30, an external storage device 40, a nurse call 50, and a terminal 60.

The vital information sensor 10 measures the vital information (biological information) of the care recipient who uses the bed 3. The biometric information includes the respiratory rate, heart rate, body movement, etc. of the care recipient. The vital information sensor 10 measures the biological information of the care recipient based on the vibration emitted from the body of the care recipient.

The vital information sensor 10 is formed in a sheet shape. As shown in FIG. 1, the vital information sensor 10 is arranged between the bed 3 and the mattress laid on the bed 3. The vital information sensor 10 measures the vital information of the care recipient while sitting on the mattress. This makes it possible to measure biometric information without restraining the care recipient.

The environmental information sensor 20 can measure information (environmental information) about the environment around the place where it is installed. The environmental information sensor 20 is installed inside the room 2. The environmental information sensor 20 includes an illuminance sensor 21 and a motion sensor 22.

The illuminance sensor 21 is a sensor capable of measuring illuminance. The illuminance sensor 21 can measure the illuminance at predetermined time intervals (for example, every 10 minutes). In the illustrated example, an example in which the illuminance sensor 21 is provided on the wall of the room 2 is shown. The installation location of the illuminance sensor 21 is not limited to the wall, and various installation locations can be adopted.

The motion sensor 22 is a sensor capable of measuring the presence or absence of a person. The motion sensor 22 can measure the presence or absence of a person at predetermined time intervals (for example, every 10 minutes). In the illustrated example, an example in which the motion sensor 22 is provided on the ceiling of the room 2 is shown. The installation location of the motion sensor 22 is not limited to the ceiling, and various installation locations can be adopted.

The control device 30 can process various types of information. The control device 30 is connected to the vital information sensor 10, the environmental information sensor 20, and an external device (external storage device 40, nurse call 50, terminal 60, etc., which will be described later) so as to be able to communicate information. The control device 30 includes a storage unit 31, a control unit 32, a display unit 33, and an input unit 34.

The storage unit 31 stores various programs, information acquired from the vital information sensor 10 and the environmental information sensor 20, and the like. The storage unit 31 is composed of an HDD, a RAM, a ROM, and the like.

The control unit 32 executes the program stored in the storage unit 31. The control unit 32 is composed of a CPU.

The display unit 33 displays various types of information. The display unit 33 is composed of a liquid crystal display or the like.

The input unit 34 is for inputting various kinds of information. The input unit 34 is composed of a keyboard, a mouse, and the like.

As described above, a general personal computer or the like can be used as the control device 30.

The external storage device 40 can store information such as past care records. Here, the care record is a record of care contents for various care recipients. Care records include records of past assessments performed by the caregiver. As the record of the above assessment, a record evaluated as appropriate according to a predetermined standard can be adopted. As the above evaluation, for example, an evaluation considering whether or not the caregiver who has performed the assessment has a certain number of years of experience (for example, 10 years or more), the satisfaction level of the care recipient, and the like can be adopted. In addition, care records include, for example, meal records (quantity and time), water records (quantity and time), excretion records (quantity and time, number of times, quality), medication records (time and type), and living organisms. Information records (body temperature, blood pressure, pulse, blood oxygen concentration), etc. are included. The care record is input via, for example, the input unit 34. The external storage device 40 is provided outside the control device 30.

The nurse call 50 is a device that notifies the care recipient to call a caregiver or a nurse. The nurse call 50 notifies by the operation of the operation unit (not shown) installed in the room 2. The nurse call 50 can also be notified by the control of the control unit 32. The nurse call 50 is installed at an appropriate nurse station. The nurse call 50 has a display unit capable of outputting (displaying) arbitrary information.

The terminal 60 can input / output various information related to long-term care. The terminal 60 has an operation unit capable of inputting arbitrary information and a display unit capable of outputting (displaying) arbitrary information. The terminal 60 is configured to be portable to the caregiver. As the terminal 60, a mobile information terminal (smartphone) that can be carried and communicated by the caregiver, a tablet, or the like can be used.

The control unit 32 as described above can determine the posture of the care recipient by using the measured value of the vital information sensor 10. For example, the control unit 32 can determine whether the care recipient is lying or sitting. In addition, the control unit 32 can determine whether or not the care recipient is in bed (in a state of being on the bed 3). The control unit 32 can determine the presence of the care recipient based on the measured value of the vital information sensor 10.

In addition, the control unit 32 can perform processing related to sleep of the care recipient based on the measured value of the vital information sensor 10. The control unit 32 can determine whether the care recipient has fallen asleep or awakened based on the measured value of the vital information sensor 10. Further, the control unit 32 can calculate the sleep efficiency from the measured value of the vital information sensor 10. Here, the sleep efficiency is the ratio of the sleep time (time from falling asleep to awakening) to the bedtime. Here, the bedtime is the time when the care recipient is lying on the bed 3 at night (the time when the vital information sensor 10 determines that the care recipient is lying down). be.

Further, the control unit 32 can perform processing using the measured value of the vital information sensor 10 in addition to the processing related to the sleep of the care recipient. For example, the control unit 32 determines whether the care recipient has an abnormality in physical condition or needs assistance such as excretion based on the respiratory rate, heart rate, body movement, etc. of the care recipient measured by the vital information sensor 10. Can be done.

Further, the control unit 32 can store the measurement result of the vital information sensor 10 in the storage unit 31 or the external storage device 40. Further, the measurement result can be displayed on the display unit 33 or the terminal 60. In addition, the control unit 32 can perform notification via the nurse call 50 or the terminal 60 based on the above measurement result, if necessary. Further, the control unit 32 can store the record of the notification in the storage unit 31 or the external storage device 40.

Further, the control unit 32 can calculate the integrated illuminance (lux · h) of the room 2 illuminated by the lighting 4 and the daylight from the window by using the measured value of the illuminance sensor 21. Here, the integrated illuminance is a cumulative illuminance value that is irradiated within the measurement time. The control unit 32 can calculate the integrated illuminance of the room 2 during the daytime. Here, the daytime is the time of the day excluding the bedtime.

In addition, the control unit 32 can determine the presence of the care recipient in the room 2 by using the measured value of the motion sensor 22. Further, the control unit 32 can control the lighting 4 to be turned off when the motion sensor 22 measures the absence of the care recipient in the room 2.

The assessment support system 1 as described above can execute an assessment support process for presenting an assessment example of long-term care based on the measured values of the vital information sensor 10 and the environmental information sensor 20 and the past care record. The assessment support process is executed by the operation of an operator (for example, a caregiver). The above operation may be an operation via the input unit 34 or an operation via the terminal 60.

Hereinafter, the assessment support process will be described with reference to the flowchart of FIG.

In step S10, the control unit 32 determines whether or not the sleep efficiency is 80% or more by using the measured value of the vital information sensor 10. As the sleep efficiency, the value of the previous day (night) may be adopted, or the average value within a predetermined period (for example, one week or one month) may be adopted. When the control unit 32 determines that the sleep efficiency is 80% or more, the control unit 32 shifts to the process of step S11. On the other hand, when the control unit 32 determines that the sleep efficiency is less than 80%, the control unit 32 shifts to the process of step S17.

In step S11, the control unit 32 determines whether or not the integrated illuminance during the day measured by the illuminance sensor 21 is equal to or greater than a predetermined threshold value. The above threshold value is a value that serves as a reference for whether or not the amount of light that the care recipient is exposed to can suppress sleep during the day (the amount of melatonin that promotes sleep can be suppressed). By suppressing the amount of melatonin secreted during the day, it is possible to promote the secretion of melatonin at night, and by extension, it is possible to promote sleep at night. As the threshold value, for example, about 5000 (lp · h) to 20000 (lp · h) can be adopted. The threshold value is not limited to the above value, and for example, about 5000 (lp · h) to 10000 (lp · h) can be adopted. Further, the threshold value is not limited to the above value, and various integrated illuminance values that serve as a reference for whether or not sleep during the day can be suppressed can be adopted. Further, as the integrated illuminance, the value of the previous day (daytime) may be adopted, or the average value within a predetermined period (for example, one week or one month) may be adopted.

When the control unit 32 determines that the integrated illuminance during the day is equal to or higher than the threshold value, the control unit 32 shifts to the process of step S12. On the other hand, when the control unit 32 determines that the integrated illuminance during the day is less than the threshold value, the control unit 32 shifts to the process of step S15.

In step S12, the control unit 32 estimates from the determination results of steps S10 and S11 that the care recipient is actively spending time in the room 2 during the daytime. That is, since the care recipient spends the daytime in the room 2 relatively brightly, it is presumed that the care recipient spends the daytime actively in the room 2 without sleeping. After executing the process of step S12, the control unit 32 shifts to the process of step S13.

In step S13, the control unit 32 extracts an assessment example corresponding to the estimation result of step S12 from the past care record stored in the external storage device 40. Specifically, the control unit 32 extracts a record of the assessment performed in the case corresponding to the above estimation result (same or similar) from the past care record. In the present embodiment, the control unit 32 extracts an assessment example for encouraging exercise during the day from the past care records. After executing the process of step S13, the control unit 32 shifts to the process of step S14.

In step S14, the control unit 32 presents an extracted assessment example. The assessment example is presented, for example, by being displayed on the display unit 33, the terminal 60 carried by the caregiver, or the display unit of the nurse call 50. The control unit 32 ends the assessment support process after executing the process of step S14.

In step S15, which shifts to the case where it is determined in step S11 that the integrated illuminance during the daytime is less than a predetermined threshold value, the control unit 32 determines that the care recipient is in the room 2 during the daytime based on the determination results of steps S10 and S11. It is presumed that he is spending his time actively. That is, it is presumed that the care recipient does not sleep during the daytime and spends time actively outside the room 2 because the room 2 is relatively dark during the daytime but the sleep efficiency is relatively good. NS. After executing the process of step S15, the control unit 32 shifts to the process of step S16.

In step S16, the control unit 32 extracts an assessment example corresponding to the estimation result of step S15 from the past care record stored in the external storage device 40. In the present embodiment, the control unit 32 extracts an assessment example to check the fall risk due to going out from the past care record. After executing the process of step S15, the control unit 32 shifts to the process of step S14.

In step S17, which shifts to the case where it is determined that the sleep efficiency is less than 80% in step S10, the control unit 32 determines whether or not the integrated illuminance during the day is equal to or greater than the threshold value. When the control unit 32 determines that the integrated illuminance during the day is equal to or higher than the threshold value, the control unit 32 shifts to the process of step S18. On the other hand, when the control unit 32 determines that the integrated illuminance during the day is less than the threshold value, the control unit 32 shifts to the process of step S19.

In step S18, the control unit 32 extracts an assessment example corresponding to the determination results of steps S10 and S17 from the past care records stored in the external storage device 40. Here, from the above determination results, it is estimated that the care recipient has relatively poor sleep efficiency due to factors other than daytime sleep. That is, the care recipient is relatively poor in sleep efficiency, even though it is presumed that he / she is not sleeping during the day (because he / she spends the room 2 relatively brightly). From this, it is estimated that sleep efficiency is relatively poor due to factors other than daytime sleep.

In the present embodiment, the control unit 32 extracts an assessment example indicating that it is necessary to take measures such as adjusting the dose amount as an improvement measure other than daytime sleep from the past care record. After executing the process of step S18, the control unit 32 shifts to the process of step S14.

In step S19, which shifts to the case where it is determined in step S17 that the integrated illuminance during the daytime is less than the threshold value, the control unit 32 uses the measured value of the motion sensor 22 to allow the care recipient to stay in the room during the daytime. Determine if it is. Here, when the control unit 32 measures the occupancy for a predetermined time (for example, 6 hours) or more, the control unit 32 determines that the care recipient is in the room during the daytime. Further, as the predetermined time, the value of the previous day (daytime) may be adopted, or the average value within the predetermined period (for example, one week or one month) may be adopted. When the control unit 32 determines that the care recipient is in the room during the daytime, the control unit 32 shifts to the process of step S20. On the other hand, when the control unit 32 determines that the care recipient is not in the room during the daytime, the control unit 32 shifts to the process of step S25.

In step S20, the control unit 32 determines whether or not the care recipient is sleeping during the daytime by using the measured value of the vital information sensor 10. Here, the control unit 32 determines that the care recipient is sleeping during the day when the sleep is measured for a predetermined time (for example, 3 hours) or more. Further, as the predetermined time, the value of the previous day (daytime) may be adopted, or the average value within the predetermined period (for example, one week or one month) may be adopted. When the control unit 32 determines that the care recipient is sleeping during the daytime, the control unit 32 proceeds to the process of step S21. On the other hand, when the control unit 32 determines that the care recipient is not sleeping during the day, the process proceeds to the process of step S23.

In step S21, the control unit 32 estimates that the nighttime sleep quality of the care recipient is deteriorated from the determination results of step S10, step S17, step S19 and step S20. That is, it is presumed that the care recipient sleeps in the room 2 in a relatively dark state during the daytime. After executing the process of step S21, the control unit 32 shifts to the process of step S22.

In step S22, the control unit 32 extracts an assessment example corresponding to the estimation result of step S21 from the past care record stored in the external storage device 40. In the present embodiment, the control unit 32 extracts an assessment example for encouraging intervention by lighting 4 (such as brightening room 2 by lighting 4) and daytime exercise from past care records. After executing the process of step S22, the control unit 32 shifts to the process of step S14.

In step S23, which shifts to the case where the care recipient is determined not to sleep in the daytime in step S20, the control unit 32 is dim from the determination results of step S10, step S17, step S19 and step S20. Estimated to be spending time in the environment. That is, it is presumed that the care recipient spends the room 2 relatively dark even though he / she does not sleep during the day. After executing the process of step S23, the control unit 32 shifts to the process of step S24.

In step S24, the control unit 32 extracts an assessment example corresponding to the estimation result of step S23 from the past care record stored in the external storage device 40. In the present embodiment, the control unit 32 extracts an assessment example for promoting environmental improvement by opening and closing the lighting 4 and the curtain, and exercise during the daytime. After executing the process of step S24, the control unit 32 shifts to the process of step S14.

In step S25, which proceeds when it is determined in step S19 that the care recipient is not in the room during the daytime, the control unit 32 uses the past care records stored in the external storage device 40 to take steps S10 and S17. And an assessment example corresponding to the determination result in step S19 is extracted. Here, from the above determination result, it is estimated that the care recipient has relatively poor sleep efficiency due to the behavior outside the room 2.

In the present embodiment, the control unit 32 extracts an assessment example indicating that it is necessary to search for behavior outside the room 2 and environmental factors as an improvement measure for the behavior outside the room 2 from the past care record. After executing the process of step S25, the control unit 32 shifts to the process of step S14.

By executing the assessment support process as described above, it is possible to present the caregiver with an assessment example based on vital information and environmental information. This makes it possible to present an assessment example based on quantitative information. In addition, this makes it possible to suggest an assessment example based on an assessment performed in the past to an inexperienced caregiver. As a result, the difference in the experience of the caregiver can be filled, and the care service can be improved.

The configuration of the assessment support process described above is an example, and the assessment support process is not limited to the above configuration. For example, in the present embodiment, the control unit 32 estimates the activity of the care recipient in step S12, step S15, step S21 and step S23, and presents an assessment example based on the estimation result. However, it is not limited to such an aspect. For example, the assessment example may be presented directly based on vital information and environmental information without going through the step of estimating the activity of the care recipient.

Further, in the above-mentioned example of the assessment support process, the vital information sensor 10 is used to mainly acquire the measured values related to the sleep of the care recipient, and the assessment example is presented based on the above-mentioned measured values. It is not limited to such an aspect. For example, the measured values such as the respiratory rate and heart rate of the care recipient measured by the vital information sensor 10 and other information on the care recipient (for example, diet, water, excretion, medication, body temperature, blood pressure, pulse, blood). An example of assessment may be presented based on oxygen concentration, etc.).

(Step S14) The control unit 32 and the control unit 32, which present an assessment example of
Is provided.

With such a configuration, the long-term care service can be improved. That is, it is possible to present an assessment example based on quantitative information, and it is possible to suggest the assessment example to an inexperienced caregiver. As a result, the difference in the experience of the caregiver can be filled, and the care service can be improved.

In addition, the vital information includes at least the sleep efficiency of the care recipient.
The environmental information includes at least the integrated illuminance of the room 2.

With such a configuration, the long-term care service can be further improved. That is, it is possible to estimate the life of the care recipient based on the sleep efficiency of the care recipient and the integrated illuminance of the room 2, and it is possible to extract an assessment example based on the estimation result. As a result, more specific assessment examples can be suggested, and the long-term care service can be further improved.

In addition, the vital information includes information on the care recipient's bedtime during the day.

With such a configuration, the long-term care service can be further improved. That is, based on the information on the care recipient's bed during the daytime, it is possible to make a more specific estimation of the daytime life such as whether or not the care recipient is lying down during the daytime. As a result, more specific assessment examples can be suggested, and the long-term care service can be further improved.

In addition, the environmental information includes information on the occupancy of the care recipient during the daytime.

With such a configuration, the long-term care service can be further improved. That is, based on the daytime occupancy information of the care recipient, it is possible to make a more specific estimation of the daytime life, such as whether or not the care recipient is in the room during the daytime. As a result, more specific assessment examples can be suggested, and the long-term care service can be further improved.

The external storage device 40 according to the present embodiment is an embodiment of the storage unit according to the present invention.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above configuration, and various modifications can be made within the scope of the invention described in the claims.

For example, in the present embodiment, the vital information sensor 10 can measure the respiratory rate, heart rate, and body movement of the care recipient with a single device, but the present invention is not limited to such an embodiment. For example, the vital information sensor 10 may be configured by a separate device capable of measuring the respiratory rate, heart rate, and body movement of the care recipient.

Further, in the present embodiment, the environmental information sensor 20 includes the illuminance sensor 21 and the motion sensor 22, but the present invention is not limited to such an embodiment. The environmental information sensor 20 includes various sensors capable of measuring the environment of the room 2 such as a temperature / humidity sensor, a sound pressure sensor, and a barometric pressure sensor in place of or in addition to the illuminance sensor 21 and the human sensor 22. It may be.

Further, in the present embodiment, the vital information sensor 10 and the environmental information sensor 20 (illuminance sensor 21 and motion sensor 22) are used to estimate the daytime life of the care recipient. Not limited to. For example, the daytime life of the care recipient may be estimated by measuring the position information of the care recipient in the room 2 using a millimeter wave sensor, thermography, or the like.

Further, in the present embodiment, the threshold value as a reference for whether or not the care recipient can suppress the daytime sleep is the value of the integrated daytime illuminance measured by the illuminance sensor 21 (see step S11). , The mode is not limited to this. For example, the above threshold value may be used as the value of the color temperature during the day. Here, the color temperature is a unit that quantitatively indicates the color of light emitted by a certain light source (for example, illumination 4). When the color temperature value is large (light is cool), sleep can be suppressed, and when the color temperature value is small (light is warm), sleep can be promoted. Therefore, when the threshold value is set to the color temperature, it is conceivable to set it to a relatively large value (for example, about 6500K). In this case, a sensor (color thermometer) capable of measuring the color temperature is provided in the room 2.

Further, both the value of the integrated illuminance during the daytime and the value of the color temperature may be used as threshold values to determine whether or not the care recipient can suppress sleep during the daytime. Further, the threshold value is not limited to the integrated illuminance and the color temperature, and various values that serve as a reference for whether or not the care recipient can suppress daytime sleep can be adopted.
