Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device for recording and reporting the presence or absence of a user's abnormal condition and health condition at home or for maintaining or improving the user's health.

[0002]

2. Description of the Related Art An example of a conventional monitoring device of this type is shown in FIG. Reference numeral 1 is a biosignal detecting means for detecting a biosignal of the user such as pulse, respiration, and body temperature at the bedside, and a display means 2 for displaying a waveform of the obtained biosignal is connected. Further, in order to detect the presence or absence of abnormality, the allowable upper limit value and the allowable lower limit value of the biological signal are set in advance by the upper and lower limit value setting means 3, and the comparing means 4 compares the output with the biological signal detecting means 1 in magnitude. When the biological signal obtained by the biological signal detecting means 1 exceeds the allowable upper limit value set by the upper and lower limit value setting means 4 or falls below the allowable lower limit value,
The comparison means 4 outputs a notification signal to the notification means 5. When the notification means 5 receives this notification signal, it is configured to make an emergency notification to the monitor by an alarm buzzer (for example, JP-A-4-56561, JP-A-4-57161, JP-A-4-327832, Kaihei 4-236

[0003]

However, in the above-mentioned conventional structure, the physical condition such as normality or abnormality has to be visually judged by a specialist later. Alternatively, if the physical condition determination condition is always constant and the user to be monitored changes, it is difficult to set the physical condition determination condition appropriately each time. When determining whether it is normal or abnormal using only the signal obtained from the biological signal detection means, if the physical condition determination condition is fixedly set within the range applicable to all users, an uncertain region that cannot be unconditionally determined cannot be determined. It becomes wider and the anomaly detection capability remains low. In other words, the user's condition changes suddenly, and although an emergency condition is occurring, it is not possible to report or inform, or conversely, the user is normal but repeats unnecessary calls to the watcher (caregiver etc.). Absent.

Even if the physical condition determination condition can be set by the adjusting operation, it is difficult for a specialist to adjust the condition, and it is impossible to attach it to a daily life item (for example, a toilet seat or a bathtub) that the user changes frequently. Further, even for the same user, the physical condition determination conditions vary depending on the time zone, season, age, environmental conditions, presence / absence of diet / exercise / medicine, and mental state.

The present invention solves such a conventional problem, and presently is based on the history of biological signals collected and accumulated for each user and the physical condition determination condition appropriately set for the user. By judging the physical condition, the purpose is to actively support health management such as emergency call (critical care), prevention of disease, and early detection (primary care).

[0006]

In order to solve the above-mentioned problems, a monitoring device of the present invention comprises a bio-signal detecting means for detecting a bio-signal of a user, a setting means for setting a physical condition determination condition of the user, And a determination unit that determines the physical condition of the user based on the biological signal and the physical condition determination condition.

Further, a setting means for individually setting the physical condition determination condition is provided for each user. Further, it is provided with a time measuring means and a setting means for setting the physical condition determination condition of the user by the output of the time measuring means.

Further, there is provided an environment detecting means for detecting the surrounding environment of the user, and a setting means for setting the physical condition judgment condition of the user by the output of the environment detecting means.

[0009] Further, it is provided with an ingested substance detecting means for detecting an ingested substance of the user such as food, water and medicine, and a setting means for setting a physical condition judgment condition of the user by the output of the ingested substance detecting means.

Further, a metabolite detecting means for detecting a metabolite of the user such as urination, defecation, and sweating, and a setting means for setting a condition for judging the physical condition of the user by the output of the metabolite detecting means. Is.

[0011] Further, it is provided with a user profile input means for inputting a user's profile such as sex, age, medical history, preference, etc., and setting means for setting a physical condition determination condition of the user according to the user's profile.

Further, there is provided an informing means for emitting an informing sound by the output of the judging means. The notification means is a pager connected to the determination means by a wireless line.

[0013]

According to the present invention, according to the above configuration, the physical condition of the user is determined based on the set physical condition determination condition of the user, whether or not there is an abnormality, and the health level.

In particular, since the physical condition determination condition is set individually for each user, when a plurality of users use the same device, the physical condition is determined based on different optimal determination conditions for each user. Regarding the biological signal, the same data usually has different thresholds for normality and abnormality for each user, and when the physical condition determination condition is set for each user, the determination accuracy in the determination means improves. It also leads to early detection and notification of certain diseases.

Further, since the timekeeping means is provided, the condition for determining the physical condition also changes depending on the season, monthly, or time of day. Each person has a unique biological rhythm, and biological signals fluctuate with periodicity. By changing the physical condition determination condition according to the biological rhythm, the physical condition can be determined with higher accuracy.

Further, since the environment detecting means for detecting the surrounding environment of the user is provided, the physical condition determination condition also varies depending on the surrounding environment. Usually, a person shows some reaction (protection or adaptation) to an external stimulus called the surrounding environment. The physical condition can be determined with higher accuracy by changing the physical condition determination conditions in response to changes in the surrounding environment such as a sudden change in room temperature.

Further, since the ingestion detecting means for detecting the ingestion of the user such as food, water and medicine is provided, the detailed condition determination conditions corresponding to the ingestion and the intake of the user are set, and the accuracy is higher. The physical condition is determined.

Further, since the metabolite detection means for detecting the metabolites of the user such as urination, defecation, and sweating is provided, detailed condition determination conditions corresponding to the metabolites and the amount of the metabolites of the user are set. , The physical condition is determined with higher accuracy.

Further, since the user profile input means for inputting the user profile such as sex, age, medical history, preference, etc. is provided, the physical condition determination condition set by the setting means as basic data of the user can be constructed with higher accuracy. .

Further, by providing the notifying means for sounding the notifying sound, it is possible to promptly and surely notify when an emergency occurs. It can be notified even when the observer is sleeping.

Further, since the informing means is a pager connected to the judging means by a wireless line, it can be freely called up regardless of where the monitor is when an emergency occurs. Observers can carry this pager in their way.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. In FIG. 1, the same numbers are assigned to the same functional blocks as in the conventional example. Reference numeral 1 is a biological signal detecting means for detecting a biological signal of the user such as pulse, respiration and body temperature at the bedside. Reference numeral 6 is a timekeeping means for measuring the current year, month, day, hour, minute, second, and 7 is the ambient temperature of the user (ambient temperature in the room or temperature of daily life items in contact with the user), humidity, air flow, etc. It is an environment detecting means for detecting. Again 8
Is the user's gender, date of birth, medical history, preferences, height,
It is a user profile input means for inputting a profile such as weight. The biological signal detecting means 1, the clocking means 6, the environment detecting means 7, and the user profile inputting means 8 are connected to the setting means 9, respectively. The setting means 9 comprises a user identifying means 9a, a history updating means 9b, a user-specific data memory 9c, and a judgment threshold value adjusting means 9d. The user identifying means 9a identifies who the user is from the output of the biological signal detecting means 1 and outputs it to the history updating means 9b. In the user-specific data memory 9c, the profile of the user input by the user profile input unit 8 and the output history of the biological signal detecting unit 1, the time measuring unit 6, and the environment detecting unit 7 are separately stored for each user. . The history update means 9b sequentially updates the past output history of the biological signal detection means 1, the timekeeping means 6, and the environment detection means 7, and outputs the updated data and the profile of the user identified to the determination threshold value adjustment means 9d. To do. The determination threshold value adjusting means 9d includes a ruled database and a recurrent neural network, and automatically generates an abnormality determination condition as a function of a biological signal, a calendar (current time), and an ambient environment. The abnormality determining means 10 is the current biological signal detecting means 1, the time measuring means 6,
The configuration is such that whether the output of the environment detecting means 7 meets the abnormality determination condition set by the setting means 9 is discriminated, and if it is determined that there is an abnormality, the alarm buzzer of the notifying means 5 makes an emergency notification. The determination threshold value adjusting means 9d is based on the reference range of a healthy person defined by the profile (age, sex, etc.) of the user, and displays the biological signal of the past user, the time when the biological signal was obtained, and the ambient environment information. The normal range of the biological signal of the user is corrected by time zone and ambient environment. A display means 11 is connected to the user-specific data memory 9c, and the display means 11 is configured to display a past trend of biological signals for each user in a graph.

A specific description will be given taking the body temperature as an example of the biological signal. The body temperature is to keep the body heat production and heat dissipation in the body almost constant while corresponding to the surrounding environment, but it is usual that the temperature fluctuates by about 1 ° C. within one day. Further, there are individual differences as shown in FIG. It is believed that this is due to differences in the degree of autonomic tone. In women, metabolism is increased due to the secretion of luteinizing hormone, and the body temperature rises. That is, FIG.
It rises after ovulation and falls with the start of the next menstruation. However, the rise in body temperature may not be clear depending on the person. Also, the body temperature of old people is generally low. This is said to be due to the low thermal conductivity of the skin of the elderly. Further, comparing the body temperature of the elderly and the body temperature of the adult, in the diurnal variation, the body temperature of the elderly generally rises early in the morning and falls early in the night as shown in FIG. This is thought to be one of the causes for the old man to get up early and go to bed early, but there are individual differences. Furthermore, there is a tendency that the pattern of daily fluctuations tends to be disturbed due to insomnia at night. Also, old people do not adapt well to the environment like young people. As shown in FIG. 5, an old man does not warm up easily when taking a bath, and it is difficult to cool after bathing, but if he is in a low temperature room, he is easily affected by it and easily bathes. This is because the ability of the elderly to maintain a constant body temperature has declined.
This is why they are more likely to suffer heat stroke and frost death than adolescents. People with a cold and other fever illnesses are more likely to develop fever than adolescents. In particular, it rarely generates heat of 39 ° C or higher. Older people often have heart disease, diabetes mellitus, and cerebrovascular disease, so they are more adversely affected by fever and the surrounding high temperature environment. On the other hand, children under the age of 10 who have not completed the body temperature regulation function are more susceptible to the effects of ambient temperature or season than adults.

By the way, the body temperature of a healthy person is high in the daytime, and has a circadian rhythm of about 24 hours in which it begins to decrease before going to bed and reaches its minimum during sleep. It is not caused by daytime activity or night sleep, and it persists whether you are sleeping in bed or staying up all night. Although the shape and phase of the rhythm may change due to day-night changes, indoor lighting, social activity cycles, meals, etc., it is not a biological reaction to cyclical changes in the environment, but a natural rhythm inherent in the body. is there.

FIG. 6 shows an electric equivalent circuit of a human body heat system model based on these medical knowledges. Temperature T (K), heat flow Q (J / s), thermal resistance R in the thermal system model
(S · K / J) and heat capacity C (J / K) can be replaced with voltage V (V), current I (A), resistance R (Ω), and capacitor capacity C (F) in the electrical system model, respectively. In FIG. 6, Vs (V) corresponds to the skin temperature on the surface of the human body, and DC voltage source Es1 (V) and AC voltage source Es2 are parameters of the human body.
(V), resistance Rs1 (Ω), resistance Rs2 (Ω), and capacitor Cs (F) are defined. Es1 + Es2 (V) is heat generated inside the human body of the user, and is a lumped constant macro model in which it is in contact with the outside world via Rs1, Cs, and Rs2. Es2 (V) is a periodic oscillatory wave having an amplitude of about 1 to 2 ° C., which is synchronized with the circadian rhythm or hormone secretion rhythm of the user, and is not necessarily a sine wave. On the other hand, as the surrounding environment, all elements that transfer heat to and from the human body by conduction, convection, and radiation are involved.
Typical items are those that can be measured directly with. For example, in a highly airtight indoor environment, a DC voltage source E corresponding to the indoor temperature
a (V) and a direct-current voltage source Eb (V) corresponding to the temperature of the daily life items that come into contact with the human body are resistors Ra (Ω) and Rb, respectively.
It shall be connected to the human body surface via (Ω).
It also has a feedback for finely adjusting the output voltage of Es1 (V) according to the skin temperature Vs (V) of the human body surface.
Further, regarding the setting and updating of Es1, Es2, Rs1, Rs2, and Cs, a standard value is generated using the profile of the user, and then corrected in real time by the history of the biological signal for each user. For example, the older the elderly becomes, the lower Es1 becomes, and Rs1,
By increasing the value of Rs2, the normal body temperature is slightly lower, and the response time constant for a sudden change in ambient temperature becomes larger (the reaction becomes slower). Also, the feedback amount of Es1 fine adjustment with respect to Vs change is reduced. We think that people with a heavy weight have a large heat capacity, and have made Cs large. In the case of an adult female, the Es2 amplitude is set large. The setting of Es2 is, in addition to the general (high in the daytime) diurnal fluctuation curve, in the case of an adult female, a low-frequency component of about a one-month cycle that is synchronized with the user's body temperature fluctuation curve detected by the biological signal detecting means 1. Is synthesized. Furthermore, the constants of Es1, Es2, Rs1, Rs2, and Cs are not always constant (the human body model is not static and fixed), but fluctuate by a predetermined amount randomly or with 1 / f fluctuation. It is profitable. That is, even if the surrounding environment is unchanged, Vs has a certain width and a slight fluctuation.
Although the thermal system equivalent model shown in FIG. 6 is simplified, if the installation locations of the biological signal detecting means 1 and the environment detecting means 7 are fixed to the bedroom, toilet, bathroom, etc., the surrounding environment is unlikely to change drastically. . Living goods such as clothing and futon, which are present between the room temperature detected by the environment detection means 7 and the skin temperature of the user detected by the biological signal detection means 1, are factors that influence the thermal system model. You can think that there is no sudden change in your life.

That is, the determination threshold value adjusting means 9d sets Es1, Es2, Rs1, Rs2, and Cs as characteristic parameters for each user based on the age, sex, time of the user, average body temperature of the user from the past, and fluctuation cycle. The current normal body temperature lower limit value Tmin (° C.) and the normal body temperature upper limit value Tmax (° C.) of the user are generated at the current time C (year / month / day) and room temperature Ta.
(° C.) and the temperature of the daily necessities Tb (° C.) are created and output as a function. Here, the current time C (year / month / day) is the output of the time measuring means 6, and the room temperature Ta (° C.) and the temperature Tb (° C.) of daily life goods are the outputs of the environment detecting means 7.
Although Tmin <Tmax, the normal range width of (Tmax-Tmin) is determined according to the amount of body temperature fluctuation of the past user.

The abnormality determining means 10 is a body temperature (skin temperature) T (° C.) of the user detected by the biological signal detecting means 1 and a normal body temperature lower limit value Tmin (° C.) and a normal body temperature upper limit value set by the setting means 9. Compared with Tmax (° C), T <Tmin or T> T
In the case of max, the alarm buzzer of the notification means 5 is used for emergency notification.

Although the body temperature has been described as the biological signal here, all biological signals such as heartbeat, pulse, respiration, blood pressure, blood flow, blood oxygen saturation, electromyogram, electrocardiogram, electroencephalogram, body fat percentage, and body weight. Is also the same. For example, the case of detecting the user's pulse, respiration, and body temperature as vital signs in the near-dead period will be described with reference to FIG. 7. Near death, especially death 2
From 3 days before, the body temperature of the hyperthermia patient often drops sharply, while the pulse becomes more tachycardia, so that the death temperature crosses (C1 point in FIG. 7) in the temperature-pulse correspondence table as shown in FIG. Further, since the respiratory rate also has the same tendency as the pulse rate, it also crosses (C2 point in FIG. 7). However, tachycardia and tachypnea eventually become slow. Therefore, the setting means 9 prepares such a temperature-pulse / respiration correspondence table for each user (when the surrounding environment does not change suddenly) and a death sign crossing or respiration / body temperature crossing occurs, and an abnormality determination is made. You may do it.

Alternatively, not only the presence / absence determination but also an analog index such as a health level may be output. Further, the biological signal may be pattern-analyzed using the waveform of time-series data instead of the digitized one-point data. The presence or absence of abnormality may be determined by combining a plurality of biological signals (multivariate). Further, in order to reduce a measurement error and a variation factor at the time of detecting a biological signal, detection data may be averaged a plurality of times a day, or a large number of determination results may be used to improve the determination accuracy. The user is not limited to a person. It may be adapted to animals such as pets that emit biological signals. In general, animals cannot appeal to owners who take care of an abnormality in their own health condition, so the effect of monitoring by setting the judgment conditions that match the specified animals is great.

The normal body temperature lower limit value Tmin and the normal body temperature upper limit value Tmax may be calculated by a rule with an expert system or by referring to a predetermined table. A fuzzy membership function may be used.

The biological signal detecting means 1 and the environment detecting means 7 may be configured to be worn by the user, or a plurality of biological signal detecting means 1 and environment detecting means 7 may be embedded in each room or daily necessities. The biological signals detected from a plurality of locations and the data of the surrounding environment may be integrated and determined by network construction.

In the above configuration, since the presence / absence of abnormality is determined based on the determination threshold value (normal temperature upper / lower limit value etc.) set by the setting means 9 for each user, malfunctions are reduced.
In other words, it is possible to prevent a call to a monitor person (such as a caregiver) even when there is no abnormality, or to not be notified or to delay the notification time although it is really abnormal. Eventually, supervisor (caregiver, etc.)
This will save the trouble of regular patrols and support appropriate measures in the event of an emergency. Since the setting means 9 sets the judgment threshold value individually for each user, even when a plurality of users use the same device, different optimum judgment threshold values are automatically set for each user, and the user himself does not The physical condition can be accurately determined without being aware of it. Eventually, it will lead to early detection and notification of certain diseases. The continuous operation of this device also has the effect that health data for each user is stored in the user-specific data memory 9c without the need for a medical professional to be present there.
Especially, it is very effective for a person (living body) such as an unhealthy elderly person, a handicapped person, an infant who has difficulty complaining about his / her own health condition, or a person who has a sensory deterioration. Alternatively, it is effective in discovering a disease that is less likely to be accompanied by subjective symptoms.

Further, by providing the timing means 6 and changing the judgment threshold value in accordance with the biorhythm unique to the user, the presence or absence of abnormality can be judged with higher accuracy. Further, since the environment detecting means 7 for detecting the surrounding environment of the user is provided, the determination threshold can be changed with respect to a change in the surrounding environment such as a sudden change in room temperature, so that the determination can be performed with higher accuracy. Further, since the user profile input means 8 for inputting the profile of the user such as sex, age, past illness, preference is provided, the setting threshold value for setting the basic data of the user, which cannot be detected only by the biological signal detecting means 1, by the setting means 9. Can be reflected in. Further, by providing the notifying means 5 for sounding the notification sound, the notification at the time of occurrence of an emergency can be promptly and surely made by the sound. There is an effect that the observer can be notified even while sleeping.

Next, a second embodiment of the present invention will be described with reference to FIG. The same functional blocks as those shown in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
In FIG. 8, reference numeral 12 is an ingestion detecting means for measuring and analyzing the amount and components of the food taken by the user. Reference numeral 13 is an excrement detecting means for measuring and analyzing the amount and components of excrement excreted or urinated by the user in the toilet equipment 19. Excretions such as defecation and urination are typical of the metabolic products of the user. The setting unit 14 includes the past biological signal detection unit 1,
The physical condition determination conditions of the user are automatically set by the outputs of the ingested substance detection unit 12 and the excrement detection unit 13 and output to the physical condition determination unit 15. The physical condition determination unit 15 compares and calculates the current biological signal of the user detected by the biological signal detection unit 1 and the physical condition determination condition set by the setting unit 14, and outputs the health level of the user to the notification unit 5. To do. The notification means 5 comprises a wireless transmission means 5a and a pager 5b. The wireless transmission means 5a is connected to the pager 5b by a wireless communication line. The radio uses specific low power of 400MHz band, and 2
It is assumed that data is transmitted in one direction at a transmission rate of 400 bps. The pager 5b is configured to emit a beeping sound when updating the health level data of the determination result and inform the user of the content by liquid crystal display. Here, the biological signal detection means 1 is built in the mattress in the bed 16 and detects the pulse, respiration, and body temperature of the user on the bed 16 in a non-invasive and non-constrained manner. The ingested substance detection means 12 is built in the cooking utensil 17 and the dishwasher 18 and detects a meal menu, the components of the ingested food, the intake amount, the calories, and the like. The ingestion detection means 12 includes an image processing device for detecting the type and amount of food and a chemical sensor for analyzing the components of the food, and is attached to the cooking utensil 17 or the dishwasher 18 to ingest the food and the intake of the user. Is estimated. The excrement detection means 13 is a toilet equipment 19
It is built in and directly detects the amount of urination and defecation, components, etc.

In the above structure, since the ingestion detecting means 12 for detecting the ingestion in the user's meal is provided, the detailed condition determination conditions corresponding to the ingestion and the intake of the user are set, and the accuracy is higher. The physical condition is determined. Further, since the excrement detection means 13 for detecting the excrement of the user in the toilet equipment 19 is provided, detailed condition determination conditions corresponding to the excrement and excretion amount of the user are set, and the physical condition is determined with higher accuracy. To be done. The biological signal detection means 1 is placed on the bed 16, the ingested food detection means 12 is placed on the cooking utensil 17, and the dishwasher 1.
In addition, since the excrement detection means 13 is built in the toilet equipment 19, the user is equivalent to unconsciously receiving a medical examination in daily life, and can easily know his / her own health condition. You can

There are great differences between individuals in biosignals. It is also greatly affected by gender, age, medical history, preferences and lifestyle. Among individuals, it varies depending on the season, monthly, or time of day. Reacts and adapts to changes in the surrounding environment. Even if the surrounding environment is constant, it varies depending on the intake of food, water, medicines and the like, and metabolic products such as urination, defecation and sweating. Therefore, by reflecting the factors that change these biological signals in the physical condition determination conditions, the physical condition determination accuracy is dramatically improved.

Further, since the notification means 5 is provided with the pager 5b, it can be carried around freely, and it becomes easy for the user to be aware of the current health condition. In addition, it is easy to install and repair or replacement at the time of failure is easy. When the emergency call system is used, it is possible to call the observer immediately regardless of where they are, but since the observer is portable, there is an effect that it is completely unobtrusive to carry.

Although only the wireless transmission means 5a and the pager 5b are connected by a wireless communication line here, the biological signal detection means 1 (or the ingestion detection means 1).
2. The excrement detecting means 13) and the setting means 14 (or the physical condition determining means 15) may be connected by a wireless LAN line.
