Description

  The present invention relates to a health management apparatus that performs physical and mental health management and a program for causing the health management apparatus to function.

  In recent years, the need for home medical care and telemedicine, and the ability to constantly check for illnesses that cannot be determined through the implementation of health examinations by medical institutions, have been established at home and remotely, rather than high-performance medical equipment used in medical institutions. Portable medical diagnostic devices that can be measured have been developed. In addition, from the viewpoint of care for the elderly and care prevention that reduces the severity of care, development of home-based and portable health management devices is required.

  As a portable health diagnostic device, a portable health monitor of Patent Document 1 has been proposed. In general, there is a problem that it is not possible to always measure data when the symptom of a disease is bad only by a medical examination by a medical institution. In order to solve this problem, the portable health monitor of Patent Document 1 has a data management function and a database composed of physiological data that is a measurement result of biological information, data that records subjective health status, and the like. A health monitor system is proposed. In this portable health monitor, by collecting multiple physiological and subjective data obtained from subjects as time-series data and having a communication system function that periodically uploads data from the monitor device to the database, It has a function to automatically measure non-invasively, and to create a subjective report of the subject's psychological state and activity / environmental information. It is possible to create a health history of subjects / patients by maintaining them in time series. The subjective data is collected at a preset time by an instruction from a doctor or the like, and is collected regardless of the physiological data obtained by monitoring. Has the described problems.

Moreover, since the biological information of the subject generally varies widely in daily values, there is a problem in that the occurrence of a physical abnormality of the subject cannot be accurately detected. In Patent Document 2, in order to solve this problem, information on a biological information measurement device and an acceleration sensor that measures at least one biological information among biological information of a subject's blood pressure, pulse, respiratory rate, and blood oxygen concentration. We have proposed a system that issues a warning when there is an abnormality in multiple data. However, this known technique also has problems in the sensor and mounting method, the method of identifying data from the sensor, and the like, and has the problems described in the problems to be solved by the following invention.
US Patent No. 6095985 (US) Japanese Patent Laid-Open No. 2003-220039

  In the portable health monitor of Patent Document 1, measured biological data (physiological data) and subjective data obtained through an inquiry are simply accumulated in a database as time series data. Accordingly, it is impossible to judge a change in the mental and physical health state of the user in real time, determine a coping means corresponding to the change, give a warning to the user immediately, or prompt improvement of the state.

  Further, in the portable device of Patent Document 2, a sensor that collects a plurality of biological information is provided and averaged or comprehensive judgment is performed, so that measurement errors caused by ambient noise peculiar to portable or simple sensors and sensor errors are detected. It is said that measurement errors due to dropout can be reduced. Thus, it is possible to make a highly reliable emergency call using the result of increasing the measurement accuracy by a plurality of sensors. However, even if the measurement accuracy is increased by using a plurality of sensors, the sensor outputs an abnormal value even in a change in the user's psychological state, for example, in a normal psychological state such as tension in front of the public. A conventional portable device issues an abnormal warning even for such a change in normal psychological state, and when used for actual telemedicine, the reliability of information is low and is not practical. Furthermore, by providing a plurality of sensors, it is possible to prevent the measurement accuracy from being significantly reduced due to sensor dropout, but it is not possible to prevent missing measurements due to sensor dropout and to confirm that the sensor has dropped out. .

  The present invention adopts a highly reliable method of using the result of analyzing the sensor measurement result and the result of the inquiry to the patient, so that the credibility of the emergency call to be notified to doctors and family members via the network is achieved. Increases nature.

  First, the overall configuration of the health management apparatus, the activation of each function, and the flow of control will be described with reference to FIG. FIG. 1 shows the configuration of a mental and physical health management apparatus according to the present invention, in which a user wears two sensors for measuring biological information and carries one sensor for measuring environmental information around the user. This is an example.

  The health management apparatus includes one or a plurality of sensors 102 and 103 that measure the biological information of the user 101, a sensor 104 that measures one or a plurality of surrounding environment information, and a portable information terminal 109 in some cases. The The measurement data of the sensors 102 to 104 can be transferred to the sensors 102 to 104 and the portable information terminal 109, respectively, and the setting information can be transferred from the portable information terminal 109 to the sensors 102 to 104. Possible wireless communication functions 105 to 108 are provided.

  This time, the sensor and the portable information terminal transfer information via a wireless communication function, but it is not always necessary to transmit using wireless communication, and wired communication can also be used. A portable information terminal incorporating an environmental sensor or a biosensor can also be used.

The portable information terminal 109 also includes a data memory 110, an analysis program 111 for analyzing measurement data, an inquiry program 112 for asking questions about the health condition of the user and an environment where the user is placed, a brain A brain function test program 113 for measuring functions and a diagnosis program 115 for diagnosing a health condition from the results of the analysis program 111 and the inquiry program 112 are provided. Based on the analysis program 111, the inquiry program 112, the brain function test program 113, and the diagnosis program 115, the CPU of the portable information terminal 109 analyzes the analysis means, the inquiry means, the brain function test means, and the diagnosis. Functions as a means.
In addition, in order to perform diagnosis more accurately, a diagnosis database 114 that links disease symptoms and analysis of measurement results may be provided.

  In this embodiment, the sensor data analysis, inquiry, and diagnosis programs are executed in the portable information terminal 109. However, any terminal having the same processing capability may be used. For example, a mobile phone or an electronic dictionary is used. It is also possible to implement.

  The user 101 wears one or a plurality of sensors 102 and 103 that measure biological information on a part of the body. The sensor that measures biological information includes, for example, an accelerometer on a wrist, a leg, or a waist. Vibration sensor that measures body activity by wearing, tilt sensor that measures body tilt, gyro sensor that measures the degree of body rotation, magnetic sensor that measures body orientation, ear, wrist, hand fingers, etc. Pulse and blood flow sensors to measure the pulse, blood flow, blood oxygen saturation, body temperature sensor to be worn on the ear or armpit, breath sensor or heart rate monitor to be worn on the chest and measure the movement of the chest, etc. Examples include speech sensors, other electromyographs, biosensors, etc. that analyze a user's speech by attaching a microphone to a part of the ear or face.

In addition, the user 101 may carry a sensor 104 that measures surrounding environmental information.
Sensors that measure ambient environmental information include, for example, gas sensors, GPS position sensors, temperature sensors that measure temperature, humidity sensors, barometers, rain / snow gauges, microphones that measure environmental noise, and the amount of particulates in the air There are a particle counter that measures the electromagnetic field, an electromagnetic field intensity sensor that measures electromagnetic waves, an IR sensor that measures the passage and approach of an object, a human sensor using a camera, a seismometer, an illuminance sensor, and the like.

  The type of sensor to be worn or carried is selected according to the user's health and disease management items. FIG. 2 shows an example of health management targets (such as diseases for prevention / status management) and the types of sensors to be mounted, particularly measurement items thereof.

Next, the flow of data and processing of the present invention will be described using the flowchart shown in FIG.
The process starts from step S11. The sensors 102 and 103 that measure the biological information and the sensor 104 that measures the environment information use the wireless communication functions 105 to 107 to transfer the measurement result information to the portable information terminal 109 (step S12). The measured information may be transferred by streaming, but the measurement data may be accumulated on the sensor side and the information may be transferred periodically.

  The portable information terminal 109 stores the measurement information transferred from each sensor in the data memory 110 in time series. Next, the CPU of the portable information terminal 109 functions as an analysis unit by the analysis program 111 and analyzes the measurement result of each sensor (step S13). If the measurement result does not indicate an abnormal value, It is determined whether they are different (step S14). The analysis program 111 prepares an analysis program in accordance with the type and number of sensors carried by the user 101 and the type of disease (for health management) to be prevented or examined.

  When the output result of the analysis program 111 shows an unusual reaction (abnormal value), the portable information terminal starts an inquiry program (step S15). In addition to starting when there is an abnormality in the biometric information from the sensor, the inquiry program 112 causes the CPU to start according to a schedule, when the user recognizes a change in his / her physical condition, or when anxiety occurs in his / her physical condition, etc. The user can directly start the inquiry program.

  The inquiry program 112 allows the CPU to determine whether the abnormality in the biometric information extracted from the sensor is due to a malfunction such as a sensor failure or dropout, a change in the user's psychological state, or a change in physical condition. To ask questions. Actually, a questionnaire regarding the user's surrounding environment and the user's psychological state is conducted, and the user's subjective information is extracted. The answer to the inquiry is input to the portable information terminal 109 by the user 101 himself. (Step S16)

  Next, the CPU activates a brain function test program (step S17) and measures brain functions. The measured biological information, the output result of the analysis program, and the result of executing the inquiry and brain function test program are accumulated in time series in the data memory.

  In step S18, the data diagnosis program 115 causes the CPU to evaluate the acquired result, or to determine whether or not there is a symptom sign by comparing the result with the database 114 or referring to the medical dictionary.

  Based on the result of the diagnostic program 115, the user is notified of a symptom status notification, a symptom improvement method, and a request for improvement of the device mounting status. Notification to the user is performed by using a voice output, a vibration output, an LED display, a display display function, and the like of a portable information terminal, a sensor device, and a device dedicated to notification.

  In addition, when the portable information terminal has a communication function with a public network or an IP network, the result can be notified to a medical institution or a user's family. For example, it is possible to notify a server of a medical institution, a personal computer of a family, and the like, and further notify a doctor or family member of an inquiry or a treatment to a portable information terminal. Thus, it is possible to construct a health management system using these devices.

  In the embodiment of the present invention, the patient can recognize the action to be taken care of, the action to be taken next, the current symptom, etc. by immediately notifying the patient of the diagnosis result or the cause of the change. By taking the recorded body movement data and the results of the interview to the doctor at a later date, the doctor can correctly know the patient's medical condition without frequent visits.

Next, the Example at the time of applying the health-care apparatus of this invention to a chronic fatigue syndrome patient is shown.
Chronic fatigue syndrome is a long-lasting symptom of fatigue, depressive state, impaired thinking, and slight fever. Memory and concentration are among the revised criteria for diagnostic criteria of the US Centers for Disease Control and Prevention (CDC). Disorder, sleep disorder, and fatigue that is difficult to recover after body movement.
These symptoms cannot be clearly diagnosed only by an in-hospital examination, and at present, the symptoms are grasped by relying on the memory of the patient through an inquiry between the doctor and the patient. In the treatment, the doctor has determined whether or not the medical condition has been recovered based on the subjective content of the patient based on the past memory at the time of the inquiry.

  However, patients often have different ways of perceiving their medical condition, and recent research shows that patients remember the last pain or the most severe pain. However, there is a problem that the pain that occurred before that, or the pain that occurred continuously even though the intensity of the pain is weak, cannot be known although it is often more important for the doctor. Such a difference in the way of receiving for each patient and the ambiguity of the memory occur, so that accurate diagnosis based on the patient's memory is difficult. Therefore, the patient needs to go to the hospital frequently and receive a doctor's diagnosis, and the burden on the patient is increased.

  In recent years, therefore, research has been conducted to enable an objective numerical diagnosis of chronic fatigue syndrome rather than a diagnostic method that relies on the patient's subjective memory.

  According to the literature (1), the life rhythm of a person's sleeping state and awakening state has a periodicity which repeats normally in 24 hours. However, the rhythm of chronic fatigue syndrome patients loses its periodicity after strenuous exercise, and deviates from the usual 24 hours. This tendency is less likely to occur in healthy people and is more common in patients with chronic fatigue syndrome. Specifically, a vibration sensor is attached to the wrist, human body movement information is acquired by the vibration sensor, and an MCP (mean cicadian period) that is a daily rhythm of the person is calculated. It has been found that the MCP value after a person's intense exercise is 23.86 hours in a healthy person, whereas it is 24.20 hours in a patient with chronic fatigue syndrome. It is possible to determine the possibility of the subject's chronic fatigue syndrome by obtaining the MCP value after the subject exercises vigorously. In the present invention, a discrimination method based on the present MCP value is used as an example of an analysis program.

  According to the literature (2), a healthy person has a remarkable difference in day and night activities compared to a chronic fatigue syndrome patient, and a healthy person and a chronic fatigue syndrome patient also have a difference in sudden activity. A vibration sensor is attached to the wrist to acquire information on body movement, and τ is calculated using the WTNMM (wavelet transform negative modulus maxima) method or α is calculated using the DFA (detrended fluctuation analysis) method. There is a clear numerical difference between syndrome patients and healthy individuals. It is possible to discriminate between a chronic fatigue syndrome patient and a healthy person by these numerical differences.

  Hereinafter, a method for calculating τ by the WTNMM method and α by the DFA method will be briefly described. WTNMM is a technique for analyzing the multifractal nature of fluctuations. First, wavelet transformation is performed as follows.

  Here, f (t) is a zero cross value at time t. The zero cross value is body movement information, which is a value obtained by taking out the AC component of the vibration sensor attached to the wrist and counting the number of accelerations of 0.01 G or more. This count value is a value indicating a tendency that the increase is large when the user is awake, and the increase is very small when sleeping. Ψ (x) is called a mother wavelet. In Non-Patent Document 2, a result obtained by differentiating a Gaussian function three times is used. Specifically, it is the following formula 2.

T.A. (B, a) indicates the size of a component of a certain section frequency a included in f (t) at time (t = b).
In TΨ [f]) (b, a) obtained by Expression 1, the trough of the wavelet function in a ^T (<a) is extracted in the interval minT, and the sum is taken. Specifically, Equation 3 is obtained. Assuming that the sum of the extracted parts is proportional to the power of τ, the value of τ is obtained by approximation. (Since there is a clear numerical difference in the value of τ between healthy subjects and patients with chronic fatigue syndrome, a threshold value can be used to distinguish between healthy subjects and patients with chronic fatigue syndrome.)
τ is a numerical value indicating whether or not there is a sudden change in the function f. When the value of τ is large, there is a steep fluctuation, and when it is small, it means a gentle fluctuation.

  On the other hand, DFA is an application of the theory of fractional brown motion, which is a model of fractal fluctuation. When the function is divided by a certain time scale n, the time series of the fractional Brownian motion can be expressed as follows.

  Here, "~" means distribution matching. F (n) is a value obtained by obtaining a cumulative value per unit time of vibration data (zero cross value) and subtracting a cumulative average value per unit time in the past from the cumulative value of the current unit time. Assume that the distribution of F (n) matches the distribution of n to the α power.

  The fluctuation of the zero cross value means the fluctuation of the Brownian motion when α = 1.5. When α is less than 1.5, either the zero-cross value has been increasing in the past but is currently decreasing, or has been decreasing in the past but is currently increasing It is shown that. When α is larger than 1.5, it indicates that the zero-cross value is either when the past and the present are also increasing or when the past is decreasing and the present is also decreasing.

The diagnostic method based on the objective numerical values of the chronic fatigue syndrome patient and the healthy person as described above is applied to a part of the analysis program of the present invention.
An embodiment when the health management device of the present invention is applied to a patient with chronic fatigue syndrome will be described with reference to FIG. In particular, for a case where the vibration sensor 301 and the temperature sensor 302 are used as sensors for collecting biological information, a measurement result analysis method, a medical condition diagnosis based on the analysis result, and an inquiry method are shown.

  In this embodiment, the patient can recognize the action to be taken care of, the action to be taken next, the current symptom, and the like by immediately feeding back the diagnosis result and the cause of the change to the patient. By taking the recorded body movement data and questionnaire results to a doctor at a later date, the doctor can correctly know the patient's medical condition without frequent visits.

As shown in FIG. 4, the user wears a vibration sensor 301 on the wrist and a temperature sensor 302 on the armpit, and collects body temperature information and body motion information, respectively. The vibration sensor attached to the wrist may be a wristwatch type, and measurement at the wrist is common at present. However, the wearing location can be selected as necessary and is not limited.
Each sensor transfers body temperature information and body motion information to the portable information terminal 303 using a wireless communication function. When each data is received, the portable information terminal activates the analysis program.

Next, a specific method of this analysis program will be described below.
The following three conditions are established to determine the possibility of chronic fatigue syndrome.
1. 1. When it is determined from the measurement result of the body temperature sensor that there is a slight fever (37.0 ° C. or higher). When intense exercise is performed within the past 3 days from the results of past interviews, and when the MCP is obtained by the calculation method described in Non-Patent Document 1 and the measured value is 24.2 hours or more 3. When the measurement result of the vibration sensor is calculated by the calculation method described in Non-Patent Document 2, τ of WTNMM and α of DFA are obtained, and τ is 0.9 or less or α is 1.5 or less

  If two or three of these three conditions are met, it is determined that the suspicion of chronic fatigue syndrome is high. If only one or none is satisfied, it is judged that the suspicion of chronic fatigue syndrome is low. Next, in order to diagnose a physical condition deterioration tendency or a recovery tendency physical condition change, the physical condition coefficient at a certain time t is defined as m (t) and is defined as follows.

Analyzing sensor data at time t, for the above three conditions,
When all three conditions are met, m (t) =-3,
When only two conditions are met, m (t) =-1
When only one condition is met, m (t) = 1,
Alternatively, m (t) = 3 when one condition is not satisfied.
That is, at a certain time t, when m (t) =-3, the subject has a very strong tendency for chronic fatigue syndrome, and conversely, if m (t) = 3, the tendency for chronic fatigue syndrome is small. Means.

In addition, using a physical condition coefficient m (t−1) that is an analysis result at time (t−1) before time t,
m (t) -m (t-1) is calculated. When m (t) -m (t-1) <0, it is determined that the symptom is worse at time t compared to time (t-1), and m (t) -m (t-1) When> 0, it is determined that the symptoms are improved.

  If it is only to check whether the symptom is changing, m (t) × m (t−1) is calculated. If this value is a positive number, the symptom is at time (t−1) and time t. If they are in the same trend and negative numbers, the current symptom can be judged to have changed from the previous symptom.

And if you need to warn a patient who has a recent tendency to be bad,
The sum of physical condition coefficients Σm (t−i) from the time (t−i) several hours ago to the current time t is obtained, and when this value falls below a certain threshold, it is determined that the symptom is very bad. Can also alert the patient.

  For example, if it is determined that the state of bad symptom continues using the past three analysis results and the threshold value of -7, the user's symptom continues to be bad when the following conditional expression is satisfied. Can be determined.

  Further, by analyzing sensor information, it is possible to detect whether or not the subject correctly wears the sensor on the body. Taking the vibration sensor as an example, if there is almost no body movement (for example, the zero cross value of 30 minutes is 10 or less), the vibration sensor may be removed from the body rather than not moving. I can judge.

  Taking a temperature sensor as an example, if the body temperature is very low (for example, 35 ° C. or lower), it is judged that the body temperature sensor may not be correctly installed on the body rather than the body temperature is really low. Can do.

  For any sensor, if there is a possibility that the sensor is detached from the body, use the interrogation function, wireless communication function, and alarm notification function for the user to check the sensor for abnormal mounting. To do.

By prompting the user for normal wearing, the wearing situation can be improved, and if it is confirmed that the wearing is not abnormal, it is possible to determine the sensor failure or the user's true physical condition, In addition, misinformation can be reduced when notifying the person other than the doctor or health / medical institution.
As described above, the measurement accuracy of the sensor and the accuracy of analysis and diagnosis can be improved.

Next, an example of an inquiry program will be described.
In the present invention, the inquiry program is started in the following three cases. An inquiry program is activated, and notifies the user of an inquiry through the alarm function or vibration function of the sensor device or portable information terminal in order to prompt the user for an inquiry (questionnaire).

1. Activation of Interrogation Program Based on Results of Analysis Program When the change in physical condition is observed according to the embodiment of the analysis program, that is, when m (t) × m (t−1) <0, the inquiry program is activated. Alternatively, when a noticeable deterioration tendency of symptoms is determined, that is, when the sum Σm (ta) of physical condition coefficients from a time (ta) several hours ago to the current time t is below a threshold Start the interview program.

  Since questionnaires to users like this are frequently conducted, the users feel troublesome and do not answer correctly. Therefore, when there is a change in physical condition or symptoms tend to worsen, interviews are conducted within the past hour. It is also possible to start an inquiry program when there is no such event.

2. Start an interview program according to a schedule Start an interview program at a preset time. In this case, the program is automatically started in the portable information terminal when the set time is reached several times a day. The interview execution time is, for example, immediately after getting up, 9 o'clock, 14 o'clock, 20 o'clock, before going to bed, etc. The inquiry program starts at the set time, and it is the interview time by the ventilation function to the user Will be notified.

3. Launching of an interview program according to the examiner's intention It is also possible to launch an interview program by user operation.
When the user recognizes that his / her physical condition is poor, or when the user feels uneasy about his / her physical condition, the user himself operates to start an inquiry program.

  The purpose of such an inquiry program startup method is to accurately record the specific symptoms and surrounding environment when the user feels unwell, and to accurately convey it at the time of the interview with the doctor. It is to be. In addition, when the user feels anxiety about the disease, the anxiety is resolved by notifying the user of the situation by comparing the analysis result of the sensor data and the inquiry result.

  The contents of the inquiry (questionnaire to users) ask questions to obtain the user's subjective information and environmental information. An example is shown below.

1. Questionnaire about user behavior and surrounding conditions ○ Where are you now (home, school, vehicle, etc.)
○ What are you doing now (standing, walking, sitting, lying)
○ Contents of meal ○ Are you relaxed or nervous as the user is aware of it?

  These questionnaires on user behavior and surrounding conditions can statistically measure what kind of environment the user was in when his / her physical condition was good or bad.

2. Questionnaire regarding users' symptoms and mood ○ Questionnaire regarding symptoms Unable to concentrate, fatigue, headache / headache, sore throat, body pain, abdominal pain / nausea, dizziness, etc. , Feelings, joyful, disgusting, uneasy, fun, sinking, worry, etc.

  The answering method for these questionnaires can take a form of not only answering whether or not it is a feeling, but also answering the degree of bias in 20 steps, for example.

The questionnaire results as described above can be used as an element for determining whether the physical condition is deteriorated due to chronic fatigue syndrome.
For example, if the result of the analysis program shows that the physical condition coefficient m (t) is low, that is, the symptoms of chronic fatigue syndrome are high, and the result of questionnaire shows that fatigue is strong, the user has a strong tendency for chronic fatigue syndrome Is more accurately judged.

  On the other hand, when m (t) is high and the symptoms of chronic fatigue syndrome are low, if the questionnaire results in a strong feeling of fatigue, it may be a disease other than chronic fatigue syndrome. As described above, more accurate diagnosis can be performed using the questionnaire results.

  A brain function test program may be performed after the interview. There is generally a test called CPT that examines brain function. The brain function test program is implemented for the user in the form of giving it game characteristics.

Below, the example of the brain function test of this invention is shown.
★, ◆, and ▲ characters are displayed on the screen every second. For example, a rule is set such that a specific button is pressed when a star or a triangle is displayed, and a button is not pressed when a star is displayed. Characters are randomly displayed for 30 seconds at 1 second intervals, and the user recognizes the displayed characters and determines whether to press a button or not. Evaluate the correct answer rate of users' answers. If this test result is bad, the user can determine that there is a possibility that the brain function may be disturbed.

  Next, the diagnostic program comprehensively determines the analysis results of the sensor measurement data, the interview results, and the results of the brain function test, for example, converts each result as a score, and uses the total score to comprehensively determine Make a diagnosis. The diagnosis result is notified immediately to the user, notified to a doctor or family member via a public line, or recorded in a portable information terminal and can be used for a health check at a hospital later.

An example of notification to the user is shown below.
If the diagnosis shows that the symptoms of chronic fatigue syndrome are bad, symptoms such as "Your symptoms are getting worse. It may be due to intense exercise a few days ago. Avoid excessive exercise." Notify the cause and improvement method. In addition, if the diagnosis results are improving, “It seems that the condition is getting better. It's a little longer until it is completely cured.” We recommend that you consult a doctor if there is any. "

  As described above, when symptoms are bad, notify the user including the analysis result of the cause of the symptoms, and notify the user what to do to improve the symptoms. You can also.

  As described above, the present invention analyzes the measured data on-site in real time, conducts an inquiry, and informs the user of the result, thereby suppressing the worsening of the symptom of the disease, Helps improve.

  As mentioned above, although the example of the analysis method of the measurement data of a sensor, an inquiry, the content of a brain function test program, and the message notified to a user were shown, it does not restrict to this content. In particular, the method for determining whether the symptoms of chronic fatigue syndrome are bad signs or good signs can be implemented by other methods.

  Moreover, although the example of the analysis program regarding chronic fatigue syndrome and an inquiry program has been shown, the present invention is also implemented as a portable health management device that performs more accurate diagnosis from data analysis and inquiry contents for other diseases as well. Is also possible.

  In addition, this time, when the health management device of the present invention is applied to chronic fatigue syndrome, an example using only a sensor that collects biological information has been shown, but a sensor that collects environmental information around the user is used. In addition, a more accurate diagnosis is possible.

  For example, when an illuminance sensor is added as an environmental sensor, daytime and nighttime activities can be more clearly distinguished, sleep depth can be measured from body movements during sleep, etc. Therefore, a more accurate and comprehensive diagnosis becomes possible. Similarly, if the noise around the user is measured using a sound sensor, the difference in physical activity when the user is in a crowded environment or a quiet environment can be discriminated, so that the depressed state can be grasped more accurately. In addition, since it is possible to determine the degree of conversation response, such as whether the conversation with the other party can be continued or whether the conversation ends immediately, it is possible to more accurately determine fatigue.

Next, as an embodiment of the present invention using an environmental sensor, an example of a health management device for chemical substance hypersensitivity is shown.
Chemical hypersensitivity, as represented by sick house syndrome, will not change the patient's physical condition at all unless the chemical is exposed to the patient. Therefore, when a chemical hypersensitivity patient receives a diagnosis of a doctor, the chemical substance causing the symptom is not exposed on the spot, so that the diagnosis becomes difficult. Therefore, even if there are symptoms due to chemical sensitivity, seizures occur, and the patient suffers, the doctor cannot diagnose the condition, and the doctor must make a diagnosis only by confirming with the patient.

  In addition, the patient himself becomes difficult to move after the seizure is severe, resulting in a worsening of the condition. Therefore, in the present invention, it is possible to provide a health management device that solves the above problems.

An example in which the health management device according to the present invention is used for health management of chemical sensitivity is shown.
A health management device for chemical substance hypersensitivity includes an environmental sensor that detects a gas concentration and a portable information terminal that has the same inquiry function as the example of the chronic fatigue syndrome.
The inquiry program can be activated when the gas concentration exceeds a threshold by the gas sensor, or can be activated by the user when the user feels a change in physical condition, or can be activated by scheduling.

  It has been confirmed that a significant difference can be obtained when a patient is exposed to chemicals and a healthy person when exposed to gas and under normal conditions. FIGS. 5 and 6 show the experimental results of 13 chemical hypersensitivity patients and 12 healthy subjects. FIG. 5 shows the types and concentrations of gases that cause the patient to change their physical condition. In addition, Fig. 6 asks patients about physical symptoms such as palpitation and nausea and moods such as anxiety, and compares the state of symptoms at the time of gas exposure with the normal state. It shows the contents of the interview where the difference was recognized. It can be seen from FIG. 6 that it is possible to determine whether or not a patient has symptoms of chemical hypersensitivity by conducting these questions. Further, FIG. 5 shows that a patient with a chemical substance hypersensitivity is completely different from a healthy person and develops symptoms at a very low gas concentration. The result of the gas concentration in FIG. 5 and the result of the inquiry content in FIG. 6 are adopted as determination of a value different from the normal value of the gas sensor of the present invention and the inquiry content.

  Therefore, in the present invention, the interrogation program is started in a state in which the gas concentration is detected at a relatively low concentration (for example, 10 ppb for formaldehyde) and the user himself / herself can answer before the seizure occurs. The question about the physical symptom and mood shown in FIG. Based on the results of the interview, the diagnostic program determines whether or not there is a sign of chemical sensitivity, and if it is determined that there is a sign of chemical sensitivity, the user is notified of the gas concentration, and from that location. It is recommended to avoid this.

  As described above, patients can be promptly diagnosed at the stage of signs before the occurrence of a chemical hypersensitivity and can be detected at the stage where the user can act before the seizure occurs. You can go away and take action to relieve symptoms (for example, taking medication).

In addition, the symptoms of chemical hypersensitivity can be objectively diagnosed, and the type of gas that causes the symptoms and the gas concentration at which signs and symptoms occur can be determined, so that doctors can make appropriate diagnoses and prescriptions.
In this example, an easy-to-carry automatic gas detector or detection rod is used as the gas sensor, but a gas sensor using IR or a miniaturized gas chromatography, which has been downsized due to recent technological innovation, may be used. .

In addition, patients with chemical hypersensitivity have abnormalities in heart rate variability and physical activity not only during the day but also at night, so in addition to the gas sensor, a health management device equipped with a heart rate monitor and vibration sensor is used to diagnose signs of symptoms. It is also possible to carry out more accurately.

It is a figure which shows the structure of the health care apparatus by this invention. It is a health (disease) management object and measurement items by a sensor in the present invention. It is a flowchart which shows the flow of a process of the health care apparatus in this invention.
