Description

Technical Field

[0001] The present invention relates to a biological information acquisition device and a biological information acquisition method. Background Art

[0002] In recent years, countermeasures for dementia have become a challenge. Dementia refers to a condition in which previously normally developed intellectual functions continue to decline, resulting in impairments in multiple intellectual functions, including memory, that hinder social life. The impairment of intellectual function in dementia is considered to range from mild to severe, progressing in stages. When dementia progresses to moderate levels, it can hinder daily life. However, in mild dementia, lifestyle changes and anti-dementia medications can be effective, making early detection and treatment crucial.

[0003] Cognitive function tests for the early detection of dementia include the MMSE (Mini-mental State Examination), the Hasegawa Dementia Scale-Revised (HDS-R), the Wechsler Memory Scale-Revised (WMS-R), the ADAS-J, the Cog (the Japanese version of the Alzheimer's Disease Assessment Scale-Cognitive), the MoCA-J (the Japanese version of the Montreal Cognitive Assessment), and the FCSRT (Free and Cued Selective Reminding Test). When diagnosing dementia in medical institutions, a combination of these cognitive function tests is performed, along with neurological examinations and MRI (Magnetic Resonance Imaging). Thus, the diagnosis of dementia requires a lot of work and is therefore difficult for patients undergoing dementia examinations, which has become a factor hindering early detection.

[0004] Patent Document 1 proposes a dementia diagnosis support system that provides a simple diagnostic test for dementia in a short time during the waiting time at a medical institution.

[0008] Problems to be solved by the invention

[0009] Furthermore, the biological information measured during daily health management may include elements that are thought to change before or in conjunction with the onset of dementia or changes in cognitive function. In view of the above, an object of the present invention is to provide a biological information acquisition device that can use biological information measured as part of daily health management to determine changes in cognitive function.

[0010] Technical Solution

[0011] In order to solve the above-mentioned problems, the biological information acquisition device of the present invention can perform cognitive function examination and is characterized by having:

[0012] Cognitive function examination unit, used to examine cognitive function;

[0013] a biometric information acquisition unit that performs a biometric information acquisition process for acquiring the biometric information of the user; and

[0014] A cognitive function determination unit determines the state of cognitive function,

[0015] The cognitive function determination unit determines the state of the cognitive function based on the result of the cognitive function test and biological information acquired from the user.

[0016] This makes it possible to determine cognitive function taking into account factors included in biological information measured in daily health management that are thought to change before or along with the onset of dementia or changes in the state of cognitive function.

[0017] The term "changed before or accompanying" used in this specification means the following. That is, it is not limited to the situation where one of "onset of dementia" or "change in cognitive function" becomes the main factor and causes other changes (there is a so-called causal relationship). For example, it can also include situations where each changes due to other main factors such as pseudo-correlation. In addition, it does not necessarily need to be close in time. For example, information related to past events of the subject, such as "chronic lack of exercise" or "previous surgical experience", can also be determined as a risk.

[0018] In addition, biological information includes blood pressure information such as maximum blood pressure, minimum blood pressure, pulse, body composition such as weight and body fat percentage, exercise volume such as number of steps and calories burned, heart rate, electrocardiogram data, respiratory rate, body temperature, etc., but is not limited to these.

[0019] In addition, as cognitive function tests, various tests such as the well-known MMSE, Hasegawa Dementia Rating Scale-Revised (HDS-R), WMS-R, ADAS-J, Cog, MoCA-J, FCSRT, etc. can be referred to, and appropriate cognitive function tests such as tests dedicated to memory can be adopted.

[0020] Furthermore, in the present invention, it may also be that

[0021] The device further comprises: an attribute information acquiring unit for acquiring attribute information related to the attributes of the user;

[0022] The cognitive function determination unit further determines the state of the cognitive function based on attribute information related to the attribute of the user.

[0023] In this way, it is possible to determine the cognitive function that reflects the following factors: the factors are included in the attribute information related to the user's physical characteristics and daily lifestyle, and are considered to change before or along with the onset of dementia or the change in the state of cognitive function.

[0024] Here, the attribute information includes age, gender, smoking status, drinking status, obesity level, exercise habits, etc., but is not limited thereto.

[0025] Furthermore, in the present invention, it may also be that

[0026] The biological information acquisition unit acquires a variety of biological information related to the user,

[0027] The cognitive function determination unit further determines the state of the cognitive function based on the plurality of types of biological information acquired by the biological information acquisition unit.

[0028] This makes it possible to determine cognitive function that reflects an element that is thought to change before or along with the onset of dementia or a change in the state of cognitive function and that is related to a variety of biological information.

[0029] Furthermore, in the present invention, it may also be that

[0030] Equipped with: communication unit, connected to other biological information measuring devices,

[0031] The biological information acquisition unit acquires at least one biological information measured by another biological information measuring device connected via the communication unit.

[0032] The attribute information acquisition unit acquires attribute information related to the attributes of the user via another biometric information measuring device connected via the communication unit.

[0033] This allows for the acquisition of various attribute information and biometric information related to the user via other biometric information devices connected to the communication unit. This improves the accuracy of cognitive function assessments based on various biometric information believed to change before or in conjunction with the onset of dementia or changes in cognitive function, as well as attribute information related to the user's physical characteristics and lifestyle.

[0034] Furthermore, in the present invention, it may also be that

[0035] The cognitive function determination unit uses a determination threshold value for determining the cognitive function, and corrects the determination threshold value based on the result of the cognitive function test and the biological information acquired from the user. In addition, the cognitive function determination unit may also correct the determination threshold value based on attribute information related to the attributes of the user. In addition, the cognitive function determination unit may also correct the determination threshold value based on the multiple biological information acquired by the biological information acquisition unit. Even in such a manner, it is possible to make a determination of the cognitive function that reflects the following elements: the elements are considered to change before or in conjunction with the onset of dementia or the change in the state of cognitive function.

[0036] Furthermore, the present invention can be grasped as a method for acquiring biological information, which can perform cognitive function tests, and includes:

[0037] a cognitive function examination step for examining a user's cognitive function;

[0038] a step of acquiring biometric information of the user; and

[0039] A step of determining the state of the user's cognitive function based on the result of the cognitive function test and the biological information acquired from the user.

[0040] In this way, it is possible to make a judgment on cognitive function that takes into account and corrects the following factors: the factors are included in the biological information measured in daily health management and are believed to change before or along with the onset of dementia or the change in the state of cognitive function.

[0041] Here, biological information includes blood pressure information such as maximum blood pressure, minimum blood pressure, pulse, body composition such as weight and body fat percentage, exercise volume such as number of steps and calories burned, heart rate, electrocardiogram data, respiratory rate, body temperature, etc., but is not limited to these.

[0042] In addition, as cognitive function tests, various tests such as the well-known MMSE, Hasegawa Dementia Rating Scale-Revised (HDS-R), WMS-R, ADAS-J, Cog, MoCA-J, FCSRT, etc. can be referred to, and appropriate cognitive function tests such as tests dedicated to memory can be adopted.

[0065] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0066] <Implementation Method 1>

[0067] First, based on Figures 1 to 11An example of an embodiment of the present invention will be described. However, unless otherwise specified, the dimensions, materials, shapes, relative arrangements, etc. of the components described in this embodiment do not limit the scope of the present invention to these.

[0068] (System Configuration)

[0069] Figure 1 1 is a schematic diagram showing a configuration example of a biological information measuring system 1 as a biological information acquiring device according to this embodiment. Figure 1 As shown, the biological information measurement system 1 includes a blood pressure monitor 10 as a biological information measuring device and a smartphone 20 as a terminal. The blood pressure monitor 10 and the smartphone 20 are capable of communicating. The communication method is not particularly limited, but for example, wireless communication methods such as Bluetooth (registered trademark), infrared communication, and ultrasonic information transmission, as well as wired communication methods connected via cables or connectors, can be used.

[0070] In addition, Figure 1 In the embodiment, the biological information measuring devices 30 and 40 are connected to the smartphone 20 in a manner capable of communicating with the smartphone 20. Here, a weight scale that measures the user's weight is used as an example of the biological information measuring device 30. However, in addition to measuring weight, the biological information measuring device 30 can also measure body composition such as body fat percentage, and can also calculate a BMI (Body Mass Index) value, which serves as a standard for obesity, based on attribute information such as age, gender, and height input by the user. In this embodiment, the attribute information includes general information indicating the user's lifestyle. Furthermore, an exercise meter that measures exercise levels such as number of steps and calorie consumption is used as an example of the biological information measuring device 40. To calculate exercise levels such as calorie consumption, the biological information measuring device 40 can also input attribute information such as the user's age, gender, weight, height, and whether or not they exercise regularly. The biological information measuring device 30 stores measurement results 31, such as weight, body fat percentage, and BMI, in its own memory, along with the time of measurement and attribute information. Similarly, in the biological information measuring device 40, the measured amount of exercise, such as the number of steps and calories burned, is recorded as measurement results 41 in the device's own memory, along with information about the time and attribute information of the measurement. It should be noted that in each biological information measuring device, the recorded measurement results are retained as a measurement history for a certain period of time. The following describes the biological information measuring system of this embodiment, using the blood pressure monitor 10 as a representative example of a biological information measuring device.

[0071] (sphygmomanometer)

[0072] The blood pressure monitor 10 in this embodiment is a measuring device that measures the user's blood pressure by the so-called oscillometric method. Figure 1 As shown, the configuration includes a sensor unit 110 , a display unit 120 , a communication unit 130 , an input unit 140 , a control unit 150 , and a storage unit 160 .

[0073] The sensor unit 110 includes a pressure sensor located on the cuff portion of the sphygmomanometer 10. It detects pulse waves from the user's blood vessels at appropriate cuff pressure. In this embodiment, the sphygmomanometer 10 can measure not only the maximum and minimum blood pressures but also the pulse rate based on the pulse waves detected by the sensor unit. Hereinafter, the maximum and minimum blood pressure values, as well as the pulse rate, are collectively referred to as blood pressure information. In this embodiment, blood pressure information corresponds to biological information.

[0074] The display unit 120 is formed of, for example, a liquid crystal display, and displays the calculated blood pressure information.

[0075] The communication unit 130 is a communication interface responsible for sending and receiving signals with the smartphone 20. In the case of a wireless communication method, the communication unit 130 is a radio wave communication antenna that sends and receives radio waves including short-range wireless communication waves, but is not limited to this, and any desired known technology can be used. In addition, the communication unit 130 can also be based on a wired communication method and can use any desired known technology. Through the communication unit 130, the inherent identification number (for example, a serial number, etc.) and information including the measured blood pressure information are sent to the sphygmomanometer respectively.

[0076] The input unit 140 is an input unit such as buttons and a touch panel display that receives input from the user, and receives various operations from the user such as turning the power on / off, starting measurement, selecting an item, and inputting attribute information.

[0077] The control unit 150 is responsible for controlling the sphygmomanometer 10 and is configured to include, for example, a CPU (Central Processing Unit). Upon receiving a user's instruction to start measurement via the input unit 140, the control unit 150 applies pressure to the cuff and, at an appropriate cuff pressure, calculates blood pressure information based on the pulse wave detected by the sensor unit 110. The calculated value is then displayed on the display unit 120. Furthermore, the control unit 150 controls the various components of the sphygmomanometer 10 to execute processing in response to user operations via the input unit 140.

[0078] The storage unit 160 is configured to include a long-term storage medium such as a flash memory in addition to a main storage device such as a RAM (Random Access Memory), and stores various information such as application programs and blood pressure information.

[0079] The measurement result recording unit 170 is a nonvolatile memory included in the storage unit 160 , and records information such as blood pressure information measured by the sensor unit 110 .

[0080] (Smartphone)

[0081] like Figure 1 As shown, the smartphone 20 includes a communication unit 210 , a touch panel display 220 , a storage unit 230 , a control unit 240 , a clock unit 250 , a sound input unit 260 , and a sound output unit 270 .

[0082] The communication unit 210 is a communication interface responsible for transmitting and receiving signals with the blood pressure monitor 10. In the case of wireless communication, the communication unit 210 is a radio communication antenna that transmits and receives radio waves, including short-range wireless communication waves. In addition to receiving measurement information transmitted from the blood pressure monitor 10, the communication unit 210 also transmits and receives radio waves with other electronic devices and base stations. The communication unit 210 may also be a wired communication unit, employing any desired known technology.

[0083] The touch panel display 220 serves as both a display unit and an input unit, displays various information to the user, and accepts various inputs from the user.

[0084] The storage unit 230 is configured to include a long-term storage medium such as a flash memory in addition to a main storage device such as a RAM, and stores various information such as application programs and biological information.

[0085] The measurement result recording unit 231 is a nonvolatile memory included in the storage unit 230 , and records information such as the blood pressure information received from the sphygmomanometer 10 and the measurement date and time of the measurement of the blood pressure information.

[0086] The cognitive function test result recording unit 232 is a nonvolatile memory included in the storage unit 230, and records the results of the cognitive function test described below. The cognitive function test results include information such as the date and time of the cognitive function test, the content of the test, and evaluation information such as the accuracy rate, but are not limited to these.

[0087] The cognitive function test information storage unit 233 is a nonvolatile memory included in the storage unit 230. It stores data such as words and illustrations used in cognitive function tests, as well as programs for implementing cognitive function tests. Furthermore, depending on the content of the cognitive function test, it also stores information regarding the time required from the provision of test information to the confirmation of the user's response to that test information.

[0088] The time adjustment information storage unit 234 is a nonvolatile memory included in the storage unit 230. The time adjustment information storage unit 234 stores time adjustment information used to adjust the blood pressure measurement time and the time from the implementation of the cognitive function test to the confirmation of the user's response. Specifically, the time adjustment information is provided to the user via the touch-panel display 220 and the audio output unit 270. It stores various information such as visual effects used to display measured values, music, animations, and conversation programs with characters, so that the information can be provided according to the necessary adjustment time.

[0089] Attribute information storage unit 235 is a nonvolatile memory included in storage unit 230. Attribute information storage unit 235 stores attribute information such as age, smoking status, educational background, and exercise habits. However, attribute information also includes general information indicating a user's "lifestyle." Furthermore, "educational background" may also include a user's "medical history," "occupational background," and "life experience."

[0090] Here, part of the attribute information may be acquired via a network connectable to the smartphone 20. For example, attribute information such as obesity, measured exercise amount, and exercise frequency may be acquired from the biological information measuring devices 30 and 40 connected via the communication unit 210.

[0091] The determination correction table 236 is a nonvolatile memory included in the storage unit 230. The determination correction table 236 stores correction information, such as correction coefficients, for correcting the thresholds used to determine the state of cognitive function. In this embodiment, the thresholds used to determine the state of cognitive function are determined based on the determination correction table 236 and the measurement results and attribute information of the biometric information. The thresholds vary depending on the measurement results and attribute information of the biometric information. Furthermore, the state of the user's cognitive function is determined based on the results of the cognitive function test and the determined thresholds.

[0092] The control unit 240 is a unit responsible for controlling the smartphone 20 , and is configured to include, for example, a CPU, and executes various programs stored in the storage unit 230 to thereby realize functions corresponding to the programs.

[0093] The clock unit 250 has a timekeeping function and stores current date and time information.

[0094] The audio input unit 260 includes a microphone that converts audio into an electrical signal, and receives input of information based on audio.

[0095] The sound output unit 270 includes a speaker that converts an electrical signal into sound, and outputs information based on sound.

[0096] (Biological Information Acquisition Method)

[0097] Figure 2 This is a flowchart showing the processing procedure of a biological information acquisition method, including cognitive function test processing, biological information acquisition processing, answer confirmation processing, and test result determination processing. Here, blood pressure information is acquired as biological information through measurement.

[0098] First, information for cognitive function testing is provided to the user via the smartphone 20 (step S1 ).

[0099] Next, the blood pressure information as biological information is measured by the sphygmomanometer 10 (step S2 ).

[0100] Next, a response to the information for the cognitive function test is received and confirmed from the user via the smartphone 20 (step S3 ).

[0101] Then, the state of cognitive function is determined based on the acquired biological information and the result of the cognitive function test (step S4).

[0102] (Cognitive function test information provision process)

[0103] As cognitive function tests, various tests such as MMSE, Hasegawa Dementia Scale-Revised (HDS-R), WMS-R, ADAS-J, Cog, MoCA-J, and FCSRT have been proposed. In the present embodiment, in order to effectively utilize the measurement time of the blood pressure information based on the sphygmomanometer 10, a test specifically for memory is performed, but it is not limited to this. In the implementation of the cognitive function test, when a prescribed time period or a prescribed interference question is required before the user's answer, the user can be asked to perform blood pressure information measurement or an operation including the measurement of the blood pressure information instead of the prescribed time period or the prescribed interference question. In this way, the cognitive function test can be easily performed together with the measurement of blood pressure information as daily health management, thereby reducing the resistance and workload caused by undergoing the cognitive function test, and early detection of dementia can be expected.

[0104] Figure 3: is a flowchart showing the processing procedure for providing cognitive function test information. The cognitive function test of this embodiment is called word reproduction, which allows the user to memorize a plurality of displayed words, and after a specified time or a specified interference task, allows the user to verbally say the previously displayed words. Including other embodiments, the cognitive function test information provision processing described below is implemented by executing the program stored in the storage unit 230 in the control unit 240 of the smartphone 20. That is, the test information providing unit is configured to include a touch panel display 220, a storage unit 230, a clock unit 250, a sound input unit 260 and a sound output unit 270, and a control unit 240 that cooperates with them. In addition, the cognitive function test function is implemented by executing the cognitive function test information provision processing and the answer confirmation processing described later.

[0105] When the date and time preset by the user as the date and time for measuring blood pressure information arrives (step S11 ), it is determined whether the date preset as the cognitive function test day has arrived (step S12 ).

[0106] If it is determined in step S12 that the cognitive function test day has not arrived, the user is requested to confirm whether to perform only blood pressure measurement through the touch panel display 220 (step S13). If in step S13, input indicating that only blood pressure measurement is to be performed is received from the user through the touch panel display 220 or through the voice input unit 260, the cognitive function test information provision process is terminated and the blood pressure measurement process described later is performed. In this case, if the blood pressure measurement process is completed, the process is terminated without performing the answer confirmation process. If in step S13, input indicating that only blood pressure measurement is not to be performed is received from the user through the touch panel display 220 or through the voice input unit 260, the process is terminated without performing the blood pressure measurement process.

[0107] If it is determined in step S12 that the cognitive function test day has arrived, a message "Do you want to take the cognitive level test?" is displayed on the touch panel display 220 of the smartphone 20 or a voice output of the message is output from the voice output unit 270 to request the user's consent (step S14).

[0108] At this time, the touch panel display 220 of the smartphone 20 displays "yes" and "no" buttons, and detects which button the user has touched to determine whether or not the user agrees. Alternatively, the smartphone 20 may receive a verbal response from the user through the voice input unit 260 to determine whether or not the user agrees.

[0109] If the user's consent is not obtained, the process proceeds to step S13.

[0110] If the user agrees, the n-word list stored in the cognitive function test information storage unit 233 of the storage unit 230 is obtained (step S15). The cognitive function test information storage unit 233 may store a word list or extract n words from a word group to form a word list.

[0111] Next, the cognitive function test method to be performed is displayed on the touch panel display 220 of the smartphone 20 to provide guidance (step S16). Here, a message guiding the cognitive function test method is displayed, such as "Next, n words will be displayed one by one. Please read and memorize the displayed words." This message can also be output by the audio output unit 270 of the smartphone 20.

[0112] Next, it is set to i=1 (step S17).

[0113] Then, if Figure 4 As shown, the first word of the word list acquired in step S15 is displayed on touch panel display 220, and a message urging the user to read the displayed word is also displayed (step S18). Here, the word "airplane" is displayed on touch panel display 220. The message urging the user to read the displayed word can also be output by audio output unit 270.

[0114] The user's voice reading the i-th word is recognized from the voices acquired through the voice input unit 260 of the smartphone 20 (step S19). If the user's voice reading the i-th word cannot be recognized within the prescribed time, a message urging the user to read the displayed word may be displayed on the touch-panel display 220 or output via the voice output unit 270. Alternatively, the process may proceed to step S20 if the user's voice reading the i-th word cannot be recognized within the prescribed time.

[0115] When the user's voice reading the i-th word is recognized, it is determined whether i=n (step S20).

[0116] When i=n is not set in step S20, i=i+1 is set (step S21), and the process returns to step S18, and the process after step S18 is repeated for the next word in the word list obtained in step S15. Figure 5As shown, different words are displayed sequentially on the touch panel display 220 of the smartphone 20. Here, the word list consists of five words: airplane, cat, cherry blossom, nose, and refrigerator. The words displayed at this time, such as transportation, animals, flowers, body parts, and household appliances, all belong to different categories. The number of words displayed, n, is not limited to 5 and can be set appropriately. When the same test is repeated multiple times, the number of words displayed increases with each cumulative number of times, such as 5 for the first time and 7 for the second time.

[0117] If i=n in step S20, the contents of the word list acquired in step S15 and the date and time when the test information was provided are stored in the cognitive function test result recording unit 232 of the storage unit 230 (step S22). Here, the date and time when the test information was provided is, for example, the date and time when the reading of the nth word was recognized.

[0118] Then, the process of providing the cognitive function test information ends.

[0119] Thus, when the process of providing the cognitive function test information is completed, as shown in FIG. Figure 2 As shown, the process proceeds to blood pressure information measurement processing (step S2).

[0120] (Blood Pressure Information Measurement Processing)

[0121] Figure 6 is a flowchart showing the blood pressure information measurement process. The blood pressure information measurement process described below, including other embodiments, is implemented by executing a program stored in the storage unit 230 in the control unit 240 of the smartphone 20 in cooperation with the blood pressure monitor 10. In this case, the blood pressure monitor 10 similarly executes the program stored in the storage unit 160 through the control unit 150. The biological information measurement unit, serving as a biological information acquisition unit, includes the touch panel display 220, storage unit 230, clock unit 250, sound input unit 260 and sound output unit 270, communication unit 210 of the smartphone 20, and the control unit 240 that cooperates with them. The biological information measurement unit also includes at least the sensor unit 110, storage unit 160, communication unit 130 of the blood pressure monitor 10, and the control unit 150 that cooperates with them.

[0122] First, the user is guided to start blood pressure measurement (step S23). Figure 7As shown, "START" and "STOP" buttons are displayed on the touch panel display 220 of the smartphone 20, and a message urging blood pressure measurement, such as "Now, take a deep breath and measure your blood pressure," is displayed on the touch panel display 220 or output from the voice output unit 270. Alternatively, a message instructing the user to wrap the cuff around the arm may be displayed on the touch panel display 220 or output from the voice output unit 270. At this point, the blood pressure monitor 10 is initialized as specified.

[0123] The process waits for the user to wrap the cuff around the arm and press the “start” button displayed on the touch panel display 220 of the smartphone 20 , or for the user to input a voice message “start” through the voice input unit 260 (step S24 ).

[0124] When the pressing of the "start" button or the sound of "start" is detected, the cuff pressure is increased (step S25). When the pressure reaches a predetermined value, the cuff pressure is gradually reduced (step S26).

[0125] Next, the highest blood pressure, lowest blood pressure, and pulse rate are calculated by a known method (step S27).

[0126] Here, it is determined whether a predetermined time has elapsed since the date and time the cognitive function test information stored in step S22 was provided (step S28). This predetermined time is the time that should be allowed between the provision of cognitive function test information, such as word display, and confirmation of the user's response, such as word reproduction, based on the content of the cognitive function test performed in step S1. This predetermined time is stored in the cognitive function test information storage unit 233 of the storage unit 230.

[0127] If it is determined in step S28 that the predetermined time has elapsed since the date and time the cognitive function test information was provided, the maximum blood pressure, minimum blood pressure, and pulse rate calculated in step S27 are displayed on the touch panel display 220 of the smartphone 20 (step S29), and the process ends. In step S29, the calculated maximum blood pressure, minimum blood pressure, and pulse rate can also be output via the audio output unit 270.

[0128] If it is determined in step S28 that the specified time has not elapsed since the date and time the cognitive function test information was provided, the process proceeds to step S30. In step S30, a time adjustment process is performed to adjust the time elapsed since the date and time the cognitive function test information was provided. As an example of this time adjustment process, the time adjustment information stored in the time adjustment information storage unit 234 of the storage unit 230 is provided to the user via the touch-panel display 220 and the audio output unit 270. The content of the time adjustment information is selected based on the difference between the time required to allow for confirmation of the response from the time the cognitive function test information was provided and the time elapsed so far. The time for the blood pressure information measurement process is determined to include the time the selected time adjustment information was provided. Examples of time adjustment information include music, videos, games, and conversations with characters. These files or programs are read from the time adjustment information storage unit 234 and reproduced or executed before being provided to the user. This time adjustment information is provided after the specified time has elapsed since the date and time the cognitive function test information was provided. Based on this difference, multiple types of information can be provided, or the provision of a single information can be suspended midway. Furthermore, the time adjustment information is not limited to the information stored in the time adjustment information storage unit 234 , and may be provided to the user from an external server via a network by a method such as streaming.

[0129] Here, time adjustment information is provided before the blood pressure information is displayed on touch panel display 220 (step S29). However, the time adjustment information may be provided in a manner that includes information related to the current blood pressure information by displaying a graph of the historical records of past blood pressure information, including the measurement result recording unit 231 of storage unit 230, while displaying the blood pressure information such as the highest blood pressure obtained in the current measurement, or by adding visual or auditory effects to the display of the current blood pressure information. Furthermore, the time adjustment information may be provided by displaying a message on touch panel display 220 or outputting it from audio output unit 270 urging the user to read aloud the displayed information such as the highest blood pressure. Furthermore, if the time to be adjusted is short, such as approximately one second, the display of the blood pressure information (step S29) may be slightly delayed as a time adjustment process.

[0130] (Answer confirmation processing)

[0131] Figure 8This is a flowchart showing the process of confirming a user's response to provided cognitive function test information. The response confirmation process described below, including other embodiments, is implemented by executing a program stored in storage unit 230 in control unit 240 of smartphone 20. Specifically, the response confirmation processing unit includes touch-panel display 220, storage unit 230, clock unit 250, audio input unit 260, audio output unit 270, and control unit 240 operating in conjunction with these components.

[0132] In step S31 , a word list used in the test is acquired from the cognitive function test result recording unit 232 of the storage unit 230 .

[0133] Next, a message urging the user to verbally answer the memorized word is displayed on touch panel display 220 (step S32). For example, a message such as "Please speak the memorized word" is displayed on touch panel display 220. The message urging the user to verbally answer the memorized word may be output via audio output unit 270, or both displayed and audio output may be performed.

[0134] Next, it is assumed that i=1 and j=0 (step S33).

[0135] Then, the voice of the i-th word is acquired from the user through the voice input unit 260 (step S34).

[0136] The acquired voice is analyzed to determine whether the word answered by the user is included in the word list acquired in step S31 (step S35).

[0137] If it is determined in step S35 that the word is included in the word list, j is set to j+1 (step S36 ), and the process proceeds to step S37 .

[0138] When it is determined in step S35 that the word is not included in the word list, the process proceeds to step S37.

[0139] In step S37, it is determined whether i=n.

[0140] If i=n in step S37, i=i+1 is set (step S38), and the process returns to step S34 to wait for the acquisition of the sound of the i+1th word.

[0141] When i=n in step S37, the number of words n that will be the subject of this cognitive function test, the number of words j that the user can reproduce, and the accuracy j / n are displayed on the touch panel display 220 and recorded in the cognitive function test result recording unit 232 of the storage unit 230 (step S39).

[0142] Next, the user is informed of the scheduled date for the next cognitive function test (step S40). For example, a message such as "Thank you for your hard work. You did a great job. To obtain the final result, please perform the test three more times. The next test will be on X day" is displayed on touch panel display 220. This message can also be output via audio output unit 270.

[0143] The next examination date is recorded in advance in the cognitive function test result recording unit 232 of the storage unit 230, and the next cognitive function test is prompted when the blood pressure information is measured on that day. In this way, by performing multiple cognitive function tests, the accuracy of the evaluation is further improved.

[0144] (Determination and Processing of Inspection Results)

[0145] Figure 9 This is a flowchart illustrating an example of a process for determining the state of a user's cognitive function based on the results of a cognitive function test (e.g., accuracy rate j / n). The determination process described below, including other embodiments, is implemented by executing a program stored in storage unit 230 in control unit 240 of smartphone 20. Specifically, the cognitive function determination unit includes touch-panel display 220, storage unit 230, clock unit 250, audio input unit 260, audio output unit 270, and control unit 240 operating in conjunction with these components.

[0146] In step S101, the accuracy rate is obtained from the cognitive function test result recording unit 232 of the storage unit 230. In step S102, the measured biological information (blood pressure information, etc.) is obtained from the measurement result recording unit 231 of the storage unit 230. In step S103, it is determined whether there is another biological information measuring device connected to the network. For example, the smartphone 20 determines that there is another biological information measuring device if there is biological information transmitted from another biological information measuring device, with the smartphone 20 itself as the destination. Otherwise, it determines that there is no other biological information measuring device. If it is determined in step S103 that there is another biological information measuring device (step S103, "Yes"), the process proceeds to step S104. If not (step S103, "No"), the process proceeds to step S105.

[0147] In step S104, the measurement results of biological information measured by other biological information measuring devices are acquired. For example, measurement results 31 such as weight, body composition such as body fat percentage, and BMI values ​​stored in memory are acquired from the biological information measuring device 30. Furthermore, measurement results 41 such as step count and calorie consumption stored in memory are acquired from the biological information measuring device 40.

[0148] In step S105, the user's attribute information is obtained from the attribute information storage unit 235 of the storage unit 230. This attribute information includes, for example, personal information such as the user's age and gender, as well as general information indicating their daily "lifestyle," such as whether they smoke, whether they drink alcohol, their obesity level, their educational background, and their exercise habits. Smoking information may include the number of cigarettes smoked per day and the hours they smoked in the past. Alcohol consumption information may include the types of alcoholic beverages, such as beer, sake, and whiskey, and the daily intake. Obesity level can be obtained from the biometric information measuring device 30, but can also be calculated based on user-entered information such as height and weight. Educational background information can include, for example, the final course of study (junior high school, high school, vocational school, junior college, or university). Educational background information may also include information such as "career experience," "career-related experience," and "life experience." Exercise habits typically include the frequency of regular weekly or monthly activities such as walking, hiking, swimming, and cycling. However, exercise habits may also include information indicating walking distance and walking time, which are part of daily lifestyle. Note that the information on lifestyle may include, for example, the frequency of biological information measurement and the frequency of medication (the number of times medication is actually taken relative to the number of times medication should be taken).

[0149] Such attribute information can be periodically acquired from another biometric measuring device connected to the network, or it can be received through the input unit of the smartphone 20. Furthermore, it can be acquired through a conversation with the user during biometric measurement or cognitive function testing via the voice output unit 270 or voice input unit 260. For example, irregular eating and sleeping habits, and the frequency of fruit and vegetable intake can be acquired as attribute information through a conversation with the user.

[0150] In step S106 , a determination threshold for determining the state of the cognitive function corresponding to the biological information and attribute information is determined. The determination threshold is determined using, for example, a correction coefficient stored in the determination correction table 236 of the storage unit 230 . Figure 10 、 Figure 11 An example of the determination correction table 236 is shown in FIG. Figure 10 In (a), a table example of correction coefficients for blood pressure measurement results is shown. Figure 10 In (b), an example of a table showing the correction coefficients related to the fluctuation range, degree of deviation, and pulse rate of the measured blood pressure value is shown. Figure 10 In the correction coefficient table (b), "aa" to "cc" shown in the item "measured value" are predetermined set values. Figure 11In FIG, an example of a table of correction coefficients related to attribute information is shown. Figure 11 In the "Corresponding Value" section, "dd" to "hh" and "jj" to "mm" are also predetermined values. Here, the correction coefficient is, for example, a correction value less than 1.0. However, the correction coefficient can also be greater than 1.0. The correction coefficient has a value for each acquired biometric information and each type of attribute information.

[0151] Taking blood pressure information as an example, generally speaking, the upper limit of the blood pressure value is preferably about 120 mmHg for systolic blood pressure, and the lower limit of the blood pressure value is preferably about 80 mmHg for diastolic blood pressure. In addition, for blood pressure values ​​diagnosed as hypertension, the upper limit of the systolic blood pressure is 140 mmHg or higher, or the lower limit of the diastolic blood pressure is 90 mmHg or higher. Therefore, if Figure 10 As shown in (a), the correction coefficient for blood pressure information is differentiated by, for example, a correction coefficient of "0.9" for a blood pressure value diagnosed as hypertension, a correction coefficient of "1.1" for an ideal blood pressure value, and a correction coefficient of "1.0" for a blood pressure value between hypertension and the ideal value. The same applies to the fluctuation range of the difference between the maximum and minimum blood pressure values, the fluctuation of the measured maximum or minimum blood pressure values ​​(e.g., the diurnal fluctuation or intraday fluctuation of the maximum or minimum blood pressure values), and the pulse rate. For example, these values ​​can also be used in place of or in combination with the above-mentioned blood pressure values ​​to calibrate the threshold.

[0152] It should be noted that such a correction coefficient can be obtained experimentally in advance. When the blood pressure reaches a value that places a high burden on the blood vessel wall through which blood flows, the value of the correction coefficient can be relatively reduced.

[0153] Figure 11 The same applies to the attribute information shown. For example, the relative value of the correction coefficient changes depending on the age group. For example, the higher the age group, the lower the correction coefficient. Regarding gender, for example, the same value can be set up until a certain age group, and then different values ​​can be set for men and women after that age group.

[0154] For each of the risk factors for lifestyle diseases, such as smoking, alcohol consumption, obesity, and exercise habits, the higher the risk factor for lifestyle diseases, the lower the correction coefficient value. For example, with regard to smoking habits, the correction coefficient value is relatively lowest if the person currently smokes. Furthermore, the correction coefficient value for past smoking habits is relatively higher than the correction coefficient for current smoking habits, and relatively lower than if the person does not smoke. With regard to alcohol consumption, the correction coefficient value is relatively lower if the daily intake exceeds the appropriate amount. With regard to obesity, for example, the correction coefficient value is relatively lower depending on the obesity level categorized by BMI. With regard to exercise habits, for example, the correction coefficient for those who do not exercise is relatively lower than that for those who do. With regard to educational background, for example, if the final course of education was categorized as a vocational school, the correction coefficient is relatively higher than if the student did not attend a vocational school.

[0155] It should be noted that in step S106, the correction coefficient may be calculated and the judgment threshold determined in a manner limited to biometric information, or the judgment threshold may be determined based on the correction coefficient calculated by combining multiple biometric information. Furthermore, when combining biometric information and attribute information, a single attribute information may be combined, or multiple attribute information of different categories may be combined.

[0156] Furthermore, the determination threshold can be determined based on a pre-assigned score for each biometric or attribute information, rather than a correction coefficient. For example, a relative index representing the degree of difference could be assigned as a score, such as "+10" for non-smoking, "-10" for existing smoking, and "-5" for past smoking habits. Alternatively, the determination threshold can be determined by adding up the total score based on the biometric and attribute information to determine a relative increase or decrease. It should be noted that the determination threshold can also be set as multiple thresholds divided into stages.

[0157] In step S107, the cognitive function test results are judged using the determined judgment threshold. For example, if the accuracy rate is above the judgment threshold, it is judged that there is no problem with the cognitive function status. Otherwise, it is judged that there is a problem with the current cognitive function status.

[0158] Furthermore, when the determination thresholds are set in multiple stages in the order of A, B, and C, for example, when the accuracy rate is above determination threshold A, it is determined that there is no problem with the state of cognitive function. Furthermore, when the accuracy rate is below determination threshold C, for example, it is determined that there is a problem with the current state of cognitive function. For an accuracy rate above determination threshold C and below determination threshold A, for example, a determination may be made based on the change in the accuracy rate over a certain period of time.

[0159] However, the results of cognitive function tests can also be determined using methods other than thresholds. For example, during the answer confirmation process, the user's cognitive function status can be determined based on the presence or absence of memory for specified words or illustrations. Such words and illustrations relevant to the determination of cognitive function can also be pre-set. By using the presence or absence of memory for specified words or illustrations to determine the state of cognitive function, determinations can be made based on memory between related words or illustrations, memory between unrelated words or illustrations, and so on, which can be expected to improve determination accuracy.

[0160] In step S108, the state of the cognitive function determined according to the determination threshold is prompted. For example, biological information, attribute information, and test results (accuracy) related to the determination can be displayed on the touch panel display 220, and the result of the determination can be displayed. In addition, notifications such as "There is no problem with the state of cognitive function" and "A problem has been found in the state of cognitive function. Please receive a professional examination at a medical institution" can also be made through the sound output unit 270. It should be noted that when the accuracy is above the above-mentioned determination threshold C and less than the determination threshold A, a notification such as "Although there is no problem with the state of cognitive function, please review your lifestyle" can also be made. In addition, a notification of giving attention to reviewing lifestyle such as giving specific measures that are considered to be related to preventing the decline of cognitive function (for example, "Take a walk for about 15 minutes every day") can also be made.

[0161] In step S109 , the determination result is recorded. For example, the determination threshold value and the determination result used for determination are recorded in association with the cognitive function test result in the cognitive function test result recording unit 232 of the storage unit 230 .

[0162] Thus, according to this embodiment, the user's cognitive function status can be determined based on the results of a cognitive function test using a threshold value calibrated based on blood pressure information and attribute information acquired as biological information. This allows for cognitive function determination that takes into account factors such as biological information measured during daily health management, and attribute information related to the user's physical characteristics and lifestyle habits, which are believed to change before or in conjunction with the onset of dementia or changes in cognitive function status. In this embodiment, cognitive function tests can be conducted using the opportunity provided by blood pressure measurements performed as part of daily health management, thereby enabling the early detection of dementia.

[0163] <Implementation Method 2>

[0164] Hereinafter, a second embodiment of the present invention will be described. Components identical to those in the first embodiment are denoted by the same reference numerals and detailed descriptions thereof will be omitted.

[0165] In this embodiment, the configuration of the biological information measurement system, the overall flow from providing cognitive function test information through blood pressure information measurement to confirming responses to the test information and determining the test results, and the details of the blood pressure measurement process are the same as those in Embodiment 1. In this embodiment, the details of the cognitive function test differ from those in Embodiment 1, so the cognitive function test process and the confirmation process for responses to the test information will be described below.

[0166] (Cognitive function test information provision process)

[0167] The cognitive function test of this embodiment is called word recognition, which requires the user to memorize multiple words displayed. After a specified time or specified interference task, multiple words are displayed in a manner that includes interference (dummy) words in addition to the previously displayed words, and the user is answered whether the displayed word is the previously displayed word.

[0168] The process of providing cognitive function test information in this embodiment is similar to Figure 3 Here, for example, the number n of words to be displayed is set to 8, as Figure 12 As shown, eight words are sequentially displayed on the touch panel display 220 of the smartphone 20 in the order of plum, radio, sparrow, cannon, eraser, skirt, table, and moon. These words are extracted from at least three or more categories.

[0169] (Answer confirmation processing)

[0170] The blood pressure measurement process is the same as that in the first embodiment, so the description is omitted. Figure 13 The answer confirmation process will be described.

[0171] First, n words (correct answer group) used in providing cognitive function test information are read from the cognitive function test result recording unit 232 of the storage unit 230, and m words (interference group) not included in the correct answer group are extracted from the word group stored in the cognitive function test information storage unit 233 to obtain a word list consisting of n+m words (step S51).

[0172] Then, a message guiding the user on how to answer the question is displayed on touch-panel display 220 (step S52). If the word displayed on touch-panel display 220 is the word displayed before the blood pressure measurement, the user should verbally answer "yes," and if it is not the word displayed before the blood pressure measurement, the user should verbally answer "no." The message guiding the user on how to answer the question may be output via audio output unit 270, or may be output both visually and audibly.

[0173] Next, it is assumed that i=1 and j=0 (step S53).

[0174] Then, the i-th word is displayed on the touch panel display 220 of the smartphone 20 (step S54). Here, as will be described later, either the word included in the correct answer group or the word not included in the correct answer group is displayed.

[0175] Next, the voice indicating the user's answer of “yes” or “no” is acquired through the voice input unit 260 (step S55 ).

[0176] The acquired sound is analyzed to determine whether the answer is correct (step S56). Specifically, if the word displayed on touch panel display 220 in step S54 is included in the correct answer group and the acquired answer is "yes," the answer is determined to be correct; if the acquired answer is "no," the answer is determined to be incorrect. Furthermore, if the word displayed on touch panel display 220 in step S54 is included in the interference group and the acquired answer is "no," the answer is determined to be correct; if the acquired answer is "yes," the answer is determined to be incorrect.

[0177] When it is determined in step S56 that the answer is correct, j=j+1 is set (step S57), and the process proceeds to step S58.

[0178] When it is determined in step S56 that the answer is incorrect, the process proceeds to step S58.

[0179] In step S58, it is determined whether i=n+m.

[0180] If i=n+m is not true in step S58, i=i+1 is set (step S59), and the process returns to step S54, where the i+1th word is displayed on the touch panel display 220. Figure 14 As shown, 16 words, namely, plum, butterfly, saw, radio, sparrow, cannon, mouth, eraser, skirt, radish, turtle, table, flute, strawberry, elephant, and moon, are sequentially displayed on touch panel display 220. Here, m is set to 8, and 8 words represented by grids are extracted as interference groups.

[0181] When i=n+m in step S58, the number n of words that will be the subject of this cognitive function test, the number m of words added as interference, the number j of words that the user can recognize, and the accuracy rate j / (n+m) are displayed on the touch panel display 220 and recorded in the cognitive function test result recording unit 232 of the storage unit 230 (step S60).

[0182] Next, the user is informed of the scheduled date for the next cognitive function test (step S61). For example, a message such as "Thank you for your hard work. You did a great job. To obtain the final result, please perform the test three more times. The next test will be on X day" is displayed on touch panel display 220. This message can also be output via audio output unit 270.

[0183] The next examination date is recorded in advance in the cognitive function examination result recording unit 232 of the storage unit 230 , and the next cognitive function examination is prompted when the blood pressure information is measured on that day.

[0184] In this embodiment, the number n of words displayed during the cognitive function test information provision process is not limited to 8 and can be set appropriately. Alternatively, when performing the same test multiple times, the number of words displayed can be set to 8 for the first test, 6 for the second test, and 12 for the third test. Furthermore, the number of words extracted as the interference group can be set to the same number as the number of words displayed during the cognitive function test information provision process, but the difficulty level can also be adjusted by increasing or decreasing the number of interference groups.

[0185] Thus, in this embodiment, it is also possible to determine cognitive function taking into account the following factors: the factors include biological information measured in daily health management, attribute information related to the user's physical characteristics and living habits, and are believed to change with the onset of dementia and changes in the state of cognitive function.

[0186] <Implementation Method 3>

[0187] Hereinafter, a third embodiment of the present invention will be described. Components identical to those in the first embodiment are denoted by the same reference numerals and detailed descriptions thereof will be omitted.

[0188] In this embodiment, the configuration of the biological information measurement system, the overall flow from providing cognitive function test information through blood pressure measurement to confirming responses to the test information, and the details of the blood pressure measurement process are the same as those in Embodiment 1. In this embodiment, the details of the cognitive function test differ from those in Embodiment 1, and therefore, the cognitive function test process and the confirmation process for responses to the test information will be described.

[0189] (Cognitive function test information provision process)

[0190] Figure 15 This is a flowchart illustrating the process of providing cognitive function test information. The cognitive function test of this embodiment is called word reproduction using images. It displays an illustration and asks the user to memorize the name of the item. After a specified time or a specified distraction task, the user is asked to verbally recite the previously displayed illustration.

[0191] The processing in step S11 and step S12 is the same as that in embodiment 1, and therefore the description thereof is omitted.

[0192] Next, a list consisting of n illustrations and the names of the items in the illustrations is obtained from the cognitive function test information storage unit 233 of the storage unit 230 (step S71). The cognitive function test information storage unit 233 may store the list or may extract n groups from a plurality of groups consisting of illustrations and item names to form the list.

[0193] Next, the cognitive function test method to be performed is displayed on the touch panel display 220 of the smartphone 20 to provide guidance (step S72). Here, a message guiding the cognitive function test method is displayed, such as "Next, n illustrations will be displayed one by one. The names of the items in the displayed illustrations will be read aloud, so please repeat and memorize them." This message can also be output by the audio output unit 270 of the smartphone 20.

[0194] Next, it is set to i=1 (step S73).

[0195] Then, if Figure 16 As shown, the first illustration in the list acquired in step S71 is displayed on touch-panel display 220, and a voice reading the name of the item in the illustration is output from voice output unit 270 (step S74). Here, an illustration of a frying pan is displayed on touch-panel display 220, and the voice output unit 270 outputs the name of the item, "frying pan." Similarly, a message urging the user to repeat the name of the item may also be displayed.

[0196] Next, the user's voice repeating the name of the item in the i-th illustration is recognized from the voices received through the voice input unit 260 of the smartphone 20 (step S75). If the user's voice reading the name of the item in the i-th illustration cannot be recognized within a predetermined time, a message urging the user to read the displayed illustration may be displayed on the touch-panel display 220 or output via the voice output unit 270. Alternatively, if the user's voice reading the name of the item in the i-th illustration cannot be recognized within a predetermined time, the process may proceed to step S76.

[0197] When the user's voice repeating the name of the item in the i-th illustration is recognized, it is determined whether i=n (step S76).

[0198] If i=n in step S76, i=i+1 is set (step S77), and the process returns to step S74, and the process after step S74 is repeated for the next illustration and item name in the list obtained in step S71. Figure 17 As shown, different illustrations are displayed sequentially on the touch panel display 220 of the smartphone 20. Here, the list consists of eight illustrations: a frying pan, a rabbit, a hat, a chicken, an airplane, a penguin, a tulip, and castanets. The illustrations displayed here all belong to different categories. The number of illustrations displayed, n, is not limited to 8 and can be set appropriately. If the same test is repeated multiple times, the number of illustrations displayed can be increased with each cumulative number of times, such as 8 for the first test and 12 for the second test.

[0199] If i=n in step S76, the contents of the list acquired in step S71 and the date and time when the examination information was provided are stored in the cognitive function examination result recording unit 232 of the storage unit 230 (step S78). Here, the date and time when the examination information was provided is, for example, the date and time when the pronunciation of the name of the item in the nth illustration was recognized.

[0200] Then, the process of providing the cognitive function test information ends.

[0201] (Answer confirmation processing)

[0202] The blood pressure measurement process is the same as that in the first embodiment, so the description is omitted. Figure 18 The answer confirmation process will be described.

[0203] First, the article name list including n article names used for providing cognitive function test information is read out and acquired from the cognitive function test result recording unit 232 of the storage unit 230 (step S81 ).

[0204] Next, a message urging the user to verbally answer the memorized item name is displayed on touch panel display 220 (step S82). For example, a message such as "Please say the memorized item name" is displayed on touch panel display 220. The message urging the user to verbally answer the memorized item name may also be output via audio output unit 270, or may be displayed and outputted audio at the same time.

[0205] Next, it is assumed that i=1 and j=0 (step S83).

[0206] Then, the voice of the article name of the i-th illustration is acquired from the user through the voice input unit 260 (step S84).

[0207] The acquired sound is analyzed to determine whether it is included in the list of item names acquired in step S81 (step S85).

[0208] If it is determined in step S85 that the article name is included in the article name list, j is set to j+1 (step S86), and the process proceeds to step S87.

[0209] When it is determined in step S85 that the article name is not included in the article name list, the process proceeds to step S87.

[0210] In step S87, it is determined whether i=n.

[0211] If i=n in step S87, the system sets i=i+1 (step S88), and returns to step S84 to wait for the sound of the article name of the i+1th illustration to be acquired.

[0212] When i=n in step S87, the number n of item names that will be the subject of this cognitive function test, the number j of item names that the user can reproduce, and the accuracy j / n are displayed on the touch panel display 220 and recorded in the cognitive function test result recording unit 232 of the storage unit 230 (step S89).

[0213] Next, the user is informed of the scheduled date for the next cognitive function test (step S90). For example, a message such as "Thank you for your hard work. You did a great job. To obtain the final result, please perform the test three more times. The next test will be on X day" is displayed on touch panel display 220. This message can also be output via audio output unit 270.

[0214] The next examination date is recorded in advance in the cognitive function test result recording unit 232 of the storage unit 230, and the next cognitive function test is prompted when the blood pressure information is measured on that day. In this way, by performing multiple cognitive function tests, the accuracy of the evaluation is further improved.

[0215] Thus, in this embodiment, it is also possible to determine cognitive function taking into account the following factors: the factors include biological information measured in daily health management, attribute information related to the user's body characteristics and lifestyle, and changes with the onset of dementia and changes in the state of cognitive function.

[0216] <Implementation Method 4>

[0217] This embodiment acquires biometric information by receiving biometric information already measured by another biometric information measuring device. Specifically, the biometric information acquisition process is implemented as a transmitted biometric information reception process. Components and processes common to those in Embodiment 1 are denoted by the same reference numerals, and detailed descriptions are omitted. Examples of biometric information include, but are not limited to, weight, body composition, exercise intensity, and body temperature.

[0218] The schematic structure of the biological information measuring system 1 as a biological information acquisition device Figure 1 This is common to the first embodiment shown in FIG. However, in this embodiment, the sphygmomanometer 10 receives measurement results as biological information already measured by another cooperating biological information measuring device via the communication unit 130 and stores them in the measurement result recording unit 170 of the storage unit 160. The sphygmomanometer 10 then transmits the measurement results stored in the measurement result recording unit 170 to the smartphone 20, thereby allowing the smartphone 20 to obtain the biological information measured by the other biological information measuring device.

[0219] The device that stores the biological information measured by another biological information measuring device may be a device having a biological information measuring function, but may not itself have a biological information measuring function.

[0220] Processing process and method of biological information acquisition including cognitive function examination processing, biological information acquisition processing and answer confirmation processing Figure 2 The same as the embodiment 1 shown.

[0221] (Cognitive function test information provision process)

[0222] Figure 19 The cognitive function test information provision process is shown in FIG. Figure 3 The different parts of the cognitive function test information providing process of the first embodiment will be described.

[0223] In this embodiment, a message "Do you want to transmit biometric information and attribute information?" is displayed on the touch panel display 220 of the smartphone 20, or a voice message of this message is output from the voice output unit 270. The user is then requested to consent to the transmission of the biometric information and attribute information (step S91).

[0224] The processing of step S12 is the same as that of embodiment 1. If it is determined in step S12 that the cognitive function test day has not arrived, the user is requested to confirm whether only the biological information is to be transmitted via touch panel display 220 or audio output unit 270 (step S92).

[0225] If, in step S92, the user receives input via the touch panel display 220 or the voice input unit 260 indicating that only the biometric information and attribute information will be transmitted, the cognitive function test information provision process ends. The biometric information transmission / attribute information reception process, described below, then proceeds. In this case, if the biometric information transmission / attribute information reception process ends, the process ends without performing the response confirmation process. If, in step S92, the user receives input via the touch panel display 220 or the voice input unit 260 indicating that only the biometric information / attribute information will not be transmitted, the process ends without performing the biometric information transmission / attribute information reception process.

[0226] (Biological Information Transmission / Attribute Information Reception Processing)

[0227] Figure 20 : is a flowchart showing the processing procedure for transmitting biological information / attribute information reception. The biological information transmission / attribute information reception process described below is realized by executing the program stored in the storage unit 230 in the control unit 240 of the smartphone 20 and cooperating with the blood pressure monitor 10. At this time, the blood pressure monitor 10 also executes the program stored in the storage unit 160 through the control unit 150. The biological information acquisition unit includes the touch panel display 220, storage unit 230, clock unit 250, sound input unit 260 and sound output unit 270, communication unit 210 of the smartphone 20, and the control unit 240 cooperating with them. The biological information acquisition unit also includes at least the storage unit 160, communication unit 130, and the control unit 150 cooperating with them of the blood pressure monitor 10.

[0228] First, the user is prompted to start transferring the biometric information / attribute information (step S93). At this point, a "Start" button is displayed on the touch panel display 220 of the smartphone 20, and a message guiding the start of transfer, such as "Transfer will begin when the start button is pressed or a start sound is heard," is displayed on the touch panel display 220 or output from the sound output unit 270.

[0229] The process waits for the user to press the "start" button displayed on the touch panel display 220 of the smartphone 20 or for the user to input a voice message "start" through the voice input unit 260 (step S94).

[0230] When the pressing of the "Start" button or the sound of "Start" is detected, the biological information and attribute information measured by another biological information measuring device are received from the measurement result recording unit 170 of the sphygmomanometer 10 (step S95).

[0231] The processing of step S28 and step S30 is the same as Figure 6 The same as the embodiment 1 shown.

[0232] If it is determined in step S28 that the predetermined time has elapsed since the date and time the cognitive function test information was provided, the biometric information received in step S95 is displayed on the touch panel display 220 of the smartphone 20 (step S96), and the process ends. In step S96, the received biometric information may also be output via the audio output unit 270.

[0233] Thus, according to this embodiment, cognitive function tests can be performed by utilizing the opportunity provided by the transmission of biological information and attribute information measured as part of daily health management. Furthermore, cognitive function assessments can be performed taking into account factors that are considered to change with the onset of dementia and changes in cognitive function, as included in the measured biological information, the user's physical characteristics, and the attribute information related to their lifestyle.

[0234] <Modification>

[0235] The processes of step S28 and step S30 in the blood pressure information measurement process may be performed in another step of the blood pressure information measurement process.

[0236] The content of the cognitive function test is not limited to that described in Embodiment 1, Embodiment 2, and Embodiment 3. Other cognitive function tests may be used, and the cognitive function tests described in Embodiment 1, Embodiment 2, and Embodiment 3 may be combined.

[0237] In addition, by changing the examination information such as the number of words and illustrations and the degree of difficulty provided as cognitive function examination information, the time required after the completion of the cognitive function examination information provision process and before the start of the answer confirmation process can be expanded or contracted, so it can also be changed to coincide with the time of the blood pressure information measurement process.

[0238] In the first embodiment, a biological information measurement system including a sphygmomanometer for measuring blood pressure information was described as a biological information measurement device. The present invention can also be applied to a biological information measurement system including a scale for measuring weight as biological measurement information, a body composition meter for measuring body composition such as body fat percentage, an activity meter for measuring activity such as steps or calories burned, and a thermometer for measuring body temperature.

[0239] In the first embodiment, the sphygmomanometer 10 is configured to measure blood pressure information independently. Figure 1 In the embodiment, the input unit 140 and the display unit 120 may be omitted, and the input of operation information and the display of various information may be performed from the smartphone 20 side. Figure 1In the embodiment, the sphygmomanometer 10 may be configured to omit the measurement result recording unit 170 and record the measurement results on the smartphone 20 side.

[0240] Furthermore, the biological information measurement system in the first embodiment includes the smartphone 20 as a terminal, but the terminal is not limited thereto and may be a fixed information terminal in addition to a mobile information terminal such as a tablet terminal or a notebook computer.

[0241] In addition, if Figure 2 As shown, the blood pressure information is measured between the provision of cognitive function test information and the confirmation of the answer from the user to the cognitive function test information. If each process is performed in this order, it is also possible that the provision of cognitive function test information and the confirmation of the first answer from the user to the cognitive function test information are performed before the measurement of the blood pressure information, and the confirmation of the second answer from the user to the cognitive function test information is performed after the measurement of the blood pressure information. It is also possible that cognitive function tests with different time periods and interfering operations required before the answer are performed, for short cognitive function tests, the first answer confirmation is performed before the measurement of the blood pressure information, and for long cognitive function tests, the second answer confirmation is performed after the measurement of the blood pressure information. In addition, for the same cognitive function test, in order to perform tests with different time periods and interfering operations required before the answer, the answer confirmation may be performed before and after the blood pressure information is measured.

[0242] In addition, Figure 6 In the blood pressure information measurement process shown, the start of blood pressure measurement is guided after the cognitive function test information provision process is completed. In the biological information measurement process taking such a blood pressure information measurement process as an example, it is also possible to arrange exercise tasks such as stepping and pedal lifting before measuring the biological information, and then measure the biological information. In this way, the exercise task can be incorporated into the measurement of the biological information as a way of adjusting the time. In this case, the timing of stepping and the number of times the pedal is lifted and lowered can be displayed on the touch panel display 220 of the smartphone 20 or output from the sound output unit 270, thereby adjusting the time.
