Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone for an elderly person or a salaried worker who is always cheerful when he or she goes out on a business trip or in a place where no one is present. It is a terminal that is used as an automatic communication device for emergency communication and lifesaving automatically using a telephone or PHS. When an error occurs, the signal from the terminal is sent to a signal transmitter (eg, a wristwatch-type telephone: a wireless device) and automatically transmitted to a wireless or dedicated telephone line. The present invention relates to a communication terminal for detecting an abnormality in a human body for sending a signal preferentially to the terminal.

[0002] In addition, even if you are conscious,
If you encounter an accident and cannot contact the surroundings even if the human body is not in bad condition, equipped with a manual switch that can intentionally send out,
No. 119 is a wireless-type human-body-abnormality detection communication terminal having a bypass capable of making an emergency call by radio or a telephone line in a manual state. Also, since the present invention is intended to be worn on a part of a human body, the physical operation such as an inclination detector or a moisture absorption detector is reduced by incorporating micro machine technology. Can be.

Since the circuit technology for miniaturization has been established with the current LSI technology, the current wristwatch-type PHS transmission circuit was used or attached to humans until the radio wave transmission circuit became ultra-compact. One of the features is that the transmitter can be wirelessly used in a cordless state with a telephone line of a home, a mobile phone, a PHS, or the like.

2. Description of the Related Art As the prior art, there are 1) a security pendant for the elderly and an alarm pendant for police to avoid molestation. This means that if you are sick or at risk of being molested, you will not be able to make an emergency call without pressing the switch yourself. Elderly people must apply for a security system and have a dedicated terminal in the room. Because it is a pendant switch, it must be hung on the neck at all times. During bathing or changing clothes before going to bed, the pendant may be removed and the user may leave the switch. Due to its large size, it is not always worn all year round when hung from the neck. In addition, they can fall down in the bathroom or in the bathroom without even noticing their family members at the time of the accident. At present, infants are not helped by many accidents such as falling into the bathroom. In such a case, if there is a means to immediately notice at the time of the occurrence of the accident, it is possible to help somehow, but it is often impossible to prevent the occurrence of the accident before it occurs. Can't the family somehow find it early? At present, there are many problems that remain. Also, only in the case of such accidents, there are many cases of suddenness, and in general, it is often impossible to press the switch by oneself because of losing consciousness. In addition, these are connected to an emergency call system using a telephone line wirelessly only when a switch is pressed.

[0005] Regarding a human body abnormality alert device of a certain manufacturer,
Some mobile phones incorporate an accelerometer and communicate abnormal information via wireless or telephone lines when there is no human body movement.In this case, if you do not attach it to the human body and put it in a bag etc. and leave it lying down , Malfunction or inability to sense. Also, a malfunction may occur when taking a nap while the mobile phone or the PHS is worn on the body. PHS
It is almost impossible to carry a cell phone or a mobile phone into the bath at all times, and it is assumed that it will be far from the actual abnormality judgment.

FIG. 6 shows a human body abnormality detection alarm for a case where the user falls down unconsciously in a working workplace. That is, FIG.
As shown in the figure, the tilt sensor 1-1, the control circuit 1-2,
Reset button 1-3, power switch 1-4, battery 1-
5 and an alarm buzzer 1-6. Tilt sensor 1
Numeral 1 outputs an electric signal corresponding to an angle 1-9 (hereinafter referred to as an inclination angle) between the central axis 1-7 and the vertical line 1-8 and sends it to the control circuit 1-2. Various methods are conceivable for the structure of the tilt sensor 1-1, such as a combination of a magnet and a Hall element. The control circuit 1-2 includes an amplifier circuit for amplifying the angle signal from the tilt sensor 1-1, a data accumulation circuit for accumulating angle data, a timer circuit for delaying a signal for sounding a buzzer for a predetermined time, and a drive circuit for driving an alarm buzzer. Consists of In order to prevent malfunction, the signal from the inclination sensor 1-1 is judged to be abnormal only when the signal continues for a predetermined time or more by the timer circuit, and the buzzer drive circuit is activated to sound the alarm buzzer 1-6.

[0007] When a human body falls down, an abnormal state is automatically judged, an alarm buzzer sounds and help can be called to the surroundings. It is a simple emergency contact alarm that acts on your behalf and informs you as an alarm on your behalf, assuming that you lose your consciousness and cannot emit words. For this reason, there is no system that automatically reports to family members, relatives and people involved in medical care directly using telephone lines or radio waves.Therefore, there are people who work in the same site or where there are workers in the same area. This is a well-known human body abnormality detection alarm for use in factories. The advantage is that it is used in a limited area, that is, when there is a worker at a remote place on the same floor, when it falls down in a place where it is buried inside the floor, or when there is a fire. It is an effective device in an emergency where it is impossible to see a fallen person because of the occurrence of smoke and falling, but only when both people are relatively close and the alarm can be heard, Useful with simple alarms. Therefore, there are the following disadvantages. If there is a distance, the alarm may not be heard. Or fall unconsciously,
There is no device that can make an emergency call if you fall into a hole or a river where no one can get around, or if you fall unconsciously in a place where you live alone or in a private room.

[0008] The principle of a pulse oximeter for judging the abnormality of the human body has been introduced in a part of the device. The pulse oximeter has been developed for medical use and is an indispensable device in ambulances and hospitals. This is a device for projecting a patient's condition on a CRT for diagnosis and for a doctor to make a judgment.
The entire system is largely one device. In addition, it is worn on the patient for use. The nurse attaches it to the patient's finger or the like at the time of measurement, and can be arbitrarily removed after the measurement is completed. This terminal is a system with a code for transferring an image to the CRT of the main unit through the code. Recently, a single pulse oximeter for climbers has been developed and sold. They have the function of measuring and displaying on the surface of the main body in order to judge the climber's health condition on the spot. It is impossible to wear it all the time because it is a device that measures arbitrarily only when necessary. In addition, at present, it is necessary to control whether or not to start measurement by mounting it by one's own will. Further, the weight of the entire main body is 60 g because two single alkaline batteries are used in the main body. Therefore, it is possible to wear the fingertip sometimes, but it is inconvenient to always wear it. From the above situation, a human body abnormality detection communication terminal dedicated to human body mounting that can automatically determine abnormalities in the physical condition and communicate emergency information using communication means for the purpose of always wearing it on the human body with the terminal of the individual device Is not present in the world.

The effect of the conventional medical pulse oximeter will be introduced.

[0010] Judgment of abnormalities in the human body 1. Based on data from emergency medical centers and doctors and the Fire and Disaster Management Agency 1) cyanosis (arterial blood oxygen partial pressure: PaO ₂ ) ...

[Measurement item] Po of blood gas or gas phase
2 and Pco2 measurements. Po2 measurement is a so-called "optode". Excitation of the substance with light causes it to fluoresce as it returns to its reference state, but it is impaired by the presence of oxygen, so by measuring light in reverse, Po2 can be measured. The measurement of pH and Pco2 is based on a measurement made so that a normal pH electrode and carbon dioxide electrode can be inserted into a blood vessel.

[Subject] 14 patients in an operating room [Method] An optical fiber sensor is inserted into an artery. The company name is CDI, 3M Health Care,
Irvine, California. [Analysis] Calibrated before insertion. Compared to blood taken from the same catheter and measured. Data from 87 cases were compared with optical fiber readings.

[Results] 1) The average of the pHa error (“bias” error = the value of the optical fiber−the value of blood sampling) is −0.032, and the accuracy (the standard error of the error) is 0.042.

The average of the Paco2 error is -3.8 mmH
g, the precision is 4.7.

The average of the error at the level of Pao2> 175 is -9.0 mmHg, and the accuracy is 23.3.

The average of the error at the level of Pao2 <175 is -8.5 mmHg, and the accuracy is 8.3.

When this error is expressed in%, Paco2 has a bias of -11.5% and accuracy of 13.3%, and Pao2 has a bias of -6.2% and accuracy of 10.0%.

2) The length of the operation is 1.6 to 8 hours with an average of 4.2 hours.

[Conclusion] The accuracy is insufficient. Especially Pac
The accuracy of o2 is insufficient. However, basically, it can be said that the possibility of use was sufficiently proved.

From the above results, the use of the pulse oximeter makes it possible to grasp the biological information of the human body. However, since the current pulse oximeter is a system used for hospitals and examinations, the mechanism of the detection unit is good, but there is a problem that the whole is large.

In addition, the present state of death and sudden illness of the elderly, the necessity of emergency lifesaving, and the like were investigated. As a result, the following describes how many sudden illnesses are involved, the involvement of critical care and the need for early detection.

<Result 1> Approximately one third of emergency rescue operations (482,612 cases / year) in the 23 wards of the Tokyo Fire Department have emergency activities for elderly people (134,119 people / year) (only in Tokyo). 3-4 times the national total firefighting firefighting white paper) <Result 2> Reason for transportation of elderly: 69.5% (sudden illness) <Result 3> Content of disease: digestive system = cerebrovascular disorder / hypertensive disease> mental disorder> circulation Organ>respiratory> other… <Result 4> Degree of illness: mild (34.4%), medium (4
6.6%), serious injuries (9.7%), serious deaths (6.3)
%) <Result 5> Notification when the elderly fell: 1) About half of them were contacted by family members or those who are taking care of them. 2) Notification of the person using a medical communication system, etc. 3) Other notice. <Result 6> Time of occurrence: There are few reports at night, and there is a report at all hours. At night, family members and nurses are sleeping and they do not notice.

<Result 7> If the treatment is performed in about 5 minutes after the emergency notification, 90% or more of the persons are saved. The slower you notice, the more likely you are to have a serious injury and the more difficult it is to resuscitate.

<Result 8> Location of sudden illness: home (71
%), Public doorway (16%), road (8%), workplace
On-site (3%), etc. <Result 9> Dissemination of the emergency call system: 9.609 households in 24 cities in 23 wards targeted at living alone or elderly couples.
154 registrations Abnormal situations may occur even for healthy people besides the elderly. If you are conscious, there are cases where people around you can help you, but if you fall unconsciously, the emergency call system is also useless at present. In addition, pulse oximeters are useful for judging abnormalities in the human body, but they are tools for medical use and for some mountaineers, and should always be worn by ordinary people such as the elderly and office workers. It is not at present.

As for the moisture absorption detector, there are existing products such as a general humidity sensor and a hygrometer, but there is no moisture absorption detector for the purpose of mounting on a human body.

[0029]

[Problems to be Solved by the Invention] As a measure for the aging society in the 21st century, the purpose is to automatically detect an abnormal state of the human body due to the trachea of the human body, and to artificially transmit it instead of human consciousness. It is a human body abnormality detection communication terminal. For example: 1) Automatic outgoing communication in an emergency of sudden illness or unconsciousness of an isolated elderly person due to the nuclear family.

2) Sudden illness or sudden death of a salaryman.

3) Emergency warning / communication when a water spill accident occurs at home for infants and the elderly.

4) Emergency communication terminal in preparation for accidents such as abduction of a young woman or child or closing of a closed room. If you are in a place where you cannot fall down or call you, you cannot move due to injury, or you are in a closed room where no one comes, etc. It is an object of the present invention to develop a wireless-type human-body-worn and human-body-abnormality detection communication terminal capable of automatically giving priority to an emergency system registered from a telephone. In addition, by introducing one chip of the C-MOS technology for the operation part and the circuit configuration, as a small and lightweight terminal,
We are developing a transmission terminal that is intended to be used as piercing fittings or a part of hearing aids and used as necessary items for the elderly and as welfare aids.

[0033]

In order to achieve the above object, a communication terminal for human body abnormality detection according to the present invention comprises a moisture absorption detector for detecting a change at the time of moisture penetration, and a human body being continuously inclined. An inclination detector for detecting the water absorption detector, and a human body mounting detector for confirming that the device is mounted on a human body, and when the human body mounting detector confirms that the device is mounted on a human body, the moisture absorption detector Alternatively, when the tilt detector detects an abnormality, a human body abnormality determination detector that automatically measures the human body information of the wearer and a transmission that wirelessly transmits the human body abnormality information measured by the human body abnormality determination detector Means.

Further, the present invention is characterized in that in the above-mentioned communication terminal for human body abnormality detection, the inclination detector is moved by the operation of the human body wearing detector and the human body abnormality detection detector, and is reset whenever the measurement result does not follow. Is what you do.

The original technology of emergency communication security is to transmit a terminal capable of emergency communication at its own discretion (press a switch) at the discretion of a conscious person. In addition, medical pulse oximeters use sensors such as clothespins on the fingertips and earlobes, and medical-related sensors allow sensors to be adsorbed on the body surface and collect biological information using electrical signals. Although there is a method for performing the data collection, the main body of the device for collecting data is a medical monitor, so it has a CRT and is large in size. Also, in the case of medical pulse oximeters and other sensors, they may be attached to the surface of the body with something like a suction pad, and they must be kept stationary while always being attached, so they can be used in everyday life Not at the moment. In addition, the current pulse oximeter can be used only in a designated room such as a hospital room or home medical care because the device is large and many cords are connected to the main body. Overseas, a method has been developed to attach a sensor to the chest surface with tape to monitor the condition of the heart and monitor it wirelessly.
In these cases, the sensor is applied to a managed sick person in a hospital, and is used for a sick person who removes the shower and takes a bath when taking a bath. Recently, a finger pulse oximeter for mountain climbing has been developed and is a type that displays blood oxygen concentration measurement. In this case, it is used to investigate the physical condition of climbers, and the size is 33 mm.
The size is 33 x 57 mm, weighs 60 g and is about the size of an egg. In the present invention, the state of the human body is determined by several detectors, and the terminal is always worn by a human. Therefore, both size and weight are limited. It is necessary that the human body abnormality detection communication terminal unit including the detection unit be 10 g or less. One of the features is that the device is operated at low power because a signal is transmitted only when necessary because the device is always of the normal OFF type.

In the present invention, it is premised that the artificial trachea is used for a normal healthy person. The artificial trachea is assumed (the three trachea in the inner ear of the human). When normal behavior is maintained while maintaining the human state while maintaining the earth axis and magnetic field. 2) By using a clock inside the human body,
Even if a healthy person is sending information to the brain that naturally controls the behavior of maintaining the state of the human body, such as falling asleep to recover from sleep and fatigue. But it is the role of the trachea. ). An artificially unconscious person in an emergency, acting on his behalf, detects a human body abnormality and automatically transmits the abnormality information via radio waves. In addition, in order to clarify the reliability of an emergency signal, an emergency call is made in the case of an abnormal state of the moisture absorption detector, the human body mounting detector, and the human body abnormality determination detector. Also,
When the state of the body is abnormal, it is determined whether the state of the blood oxygen of the human body is normal (NO) or abnormal (YES) by the judgment of the inclination detector and the human body abnormality detection detector. In case of YES, immediately
Automatic transmission from a signal transmitter (wireless) to a security service or a registered terminal via a telephone line. Currently, self-determining detectors are not used in sensors used for medical care, security and crime prevention. If a telephone line function is added, it can be transmitted anywhere. In particular, the three-half trachea in the inner ear of a human greatly affects the human walking motion, and such a function cannot be artificially created. Therefore, to artificially determine the normal behavior of the human body, 1) the switch is set when the operation accuracy setting of the tilt detector and the timer setting state and the abnormal tilt state of the human body (about 45 degrees) continue. Operate. (When returning the tilt detector during operation,
Press the reset switch. 2) After the operation, the mounting state of the device is checked by a temperature change, and if the mounting is confirmed, the detector automatically operates. 3) The emitted light (ON) activates the light emitting diode to emit visible light and infrared light. Based on the transmitted wavelength, the amount that passes through a part of the blood vessel of the human body and reaches the light receiving diode is calculated by a subtractor. 4) Obtain information for determining a normal state in a blood vessel of a human body based on the amount of current. 5) As a result, the abnormal state of the human body is confirmed based on the tilt state of the human body (abnormality determination operation) and the decrease in the amount of hemoglobin in the blood vessels of the human body, and the information is substituted for the three-half trachea. 6) If a pulse wave fluctuates significantly due to a moisture absorption detector based on moisture permeability and a human body wearing detector (body temperature, etc.) for confirming that the body is worn, an emergency radio signal Can be transmitted wirelessly. 7) In the case of a current amount at which a decrease in blood hemoglobin is recognized during emergency transmission, a signal transmitter having an emergency call radio at the 119th by an automatic radio signal operates. It is a human body abnormality detection communication terminal that can make an automatic transmission, with functions such as being artificially determined.

From the above information, it is the current state of the art that there is no radio terminal including biometric information acting as a substitute for the three-half trachea of the human body with respect to the conventional human body abnormalities. In addition, in the event of a drowning accident while playing with a toddler in the river or taking a bath for the elderly, the emergency switch can be called to the home telephone and 119 by operating the activation switch based on the moisture penetration rate in 6). it can. This protects the privacy of the wearer and ensures emergency S
OS transmission function.

[0045]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of the communication terminal for human body abnormality detection according to the present invention. In the figure, A is a moisture absorption detector, B is a human body wearing detector, C is a tilt detector, D is a human body abnormality detection detector, E is a circuit such as a subtractor, signal converter, signal amplifier, comparator, F1, F2 is a battery, G is a signal transmitter (there is an example of a wristwatch type mobile phone), H is a manual switch (manual transmission switch), I is a wireless signal, J is an emergency signal, and K is a home telephone.
L is automatic transfer, M is family / relative, etc., N is 119, O is emergency call system, Q is threshold, T is timer, U is reset. When an abnormal state of the human body is determined in an emergency, a signal is preferentially transmitted to a nearby terminal such as a home telephone, a mobile telephone, or a PHS by radio at a specific frequency. The terminal of K, such as a home telephone, a mobile phone, and a PHS, which has received the notification, is a terminal that notifies the emergency caller of the registered family member or relative M of the abnormality via a telephone line. A method of searching for a place where an abnormal call is made has been established as current technology. This is a human body abnormality detection communication terminal for contributing to an aging society as a means for sending an abnormal signal when the user falls down unconsciously to a home telephone, a mobile phone, a PHS, etc., and making an emergency contact. In particular, although it is difficult to determine the abnormality of a human body (living body), it is generally important to use the principle of operation of a pulse oximeter. However, the entire system is not required for the determination. It is most important that only the signals of the light emitting unit and the light receiving unit are set as thresholds and used as a 1 or 0 determination signal. The judgment data of a general pulse oximeter is as follows.

1) Generation of cyanosis (arterial oxygen partial pressure:
PaO ₂ ) ... Judgment reference value HP oxygen saturation SaO ₂ 80% by pulse oximeter,
If symptoms such as occurrence occur at the time of PaO ₂ 45%, it is determined that the risk factor is 90% or more.

As a criterion for judging a human body abnormality, 1. Moisture absorption detector A that detects changes during moisture penetration, and human body wearing detector B that confirms that a human body is wearing (detection to check biological information that the human body is operating due to body temperature, etc.) Container). Also, 2. Due to the configuration of the tilt detector C and the human body mounting detector B for detecting that the body is continuously tilted when the human body is abnormal, it operates when it is confirmed that the human body is partially mounted.

1. Or, 2. When one of the two detectors corresponding to the above is operated, or when an abnormal signal is caused, a human body abnormality determination detector that automatically measures the wearer's body (biological) information (blood hemoglobin amount). D
Works. After the light-emitting diode and the amount of visible light and infrared light received after passing through a part of the blood vessel of the human body are received by the light-receiving diode, and converted to an electric signal by the signal conversion / signal amplifier E and amplified, Subtractor E subtracts. If this subtraction value is larger than the threshold value as compared by the comparator E, the signal is transmitted to the signal transmitter G as an abnormal signal as abnormal information (YES) by an electric signal. If there is an abnormal signal, the signal transmitter G
A wireless signal I is sent to the PHS etc. K, and the home telephone / mobile phone / PHS etc. K is automatically transferred L to the family / relative M etc. still,
When an emergency signal is detected, an automatic transfer L is made to the 119th N or emergency call system (security line) O. The human body abnormality detection communication terminal is intended to be worn on the human body, for example, 10 to 1
This is a human body abnormality detection communication terminal characterized in that automatic determination is given with priority given to emergency communication / reporting for human body mounting for the purpose of weight reduction and size reduction (size that can be built into a hearing aid) such as 5 mm.

Specific examples of the use of the present invention include a case where the device is incorporated into a type of earring, a case where a part is inserted in a stone part of an earring, and a case where a transmitter is mounted on the back of the ear as a part of a hearing aid. Some are fitted with.

Next, the moisture absorption detector will be described with reference to FIG.

This switch has a feature of shrinkage due to moisture impregnation. A battery 202 is provided in a part of the cylindrical current-carrying portion 201, and a certain length and weight are stored in the cylindrical current-carrying portion 201 in a dry state. A moisture absorption detection unit 203 such as a horse hair, which changes in length and weight when maintained and permeates, is installed. A first contact conductive portion 204 is attached to a lower portion of the moisture absorption detecting portion 203, and the first contact conductive portion 2
A second contact conductive portion 205 is provided with a small gap from the second contact conductive portion 205. The second contact conductive portion 205 is connected to a switch 206
Is connected to the output terminal 207 through the
6, a manual reset switch 208 is connected.

The moisture absorption detector based on the moisture permeability has a stretching action when horse hair absorbs moisture. For this reason, for example, the first contact conductive portion 204 is provided in a part of the horse hair, and water enters the cylindrical conductive portion 201 from around the first contact conductive portion 204 to absorb water into the horse hair. If there is, the fiber of the horse's hair grows and changes in weight and length.
Therefore, the first contact conductive part 204 moves and makes contact with the second contact conductive part 205 to be turned on, and outputs an abnormal signal to the output terminal 207. As for the moisture absorption detector, only the horse hair part is used, so the sensor is 5 mm
Can be processed within a small size. When it is confirmed that the main body is immersed in water by 50% or more, it operates as a detector that starts the main body. As the moisture absorption detector that changes according to the moisture permeability, besides horse hair, for example, rayon, wool, or the like that contracts with moisture can be used. The advantage of horse hair is that when it dries, it shrinks back to its original size, so it naturally separates from the switch and turns off. Further, in the case of rayon or polyester material which is excellent in hygroscopicity, the weight is twice or more when impregnated with water as compared with when dried, in order to absorb water. Therefore, when the weight becomes heavy, the contact is pushed to operate. There is a second contact conductive part 205 separated by milli-order from the first contact conductive part 204 whose weight and length change due to a change in the moisture impregnation rate. 204 and the second contact conductive portion 205 come into contact with each other and conduct electricity. It is a moisture absorption detector according to the surrounding environment. In addition, when water is accidentally absorbed by the fogging detector, the non-conductive state can be set by the manual reset switch 208 of the non-conductive body. In addition, as for general hygrometers, besides horse hair, there are anemomaster temperature-humidity meters, mercury meters, tabletop hygrometers, etc. At present, they cannot be used in the present invention.

The horse hair (length 30) of the moisture absorption detector 203
mm) to the left and right, the length can be arbitrarily reduced. As a result, the detection section contracts by 1 mm or more when water is included or not. FIG.
Is about 6 mm × 7 mm, and a sensor of about 7 to 8 mm square including the output section and having a thickness of about 2 to 3 mm is possible. Also in this case, when processing is performed by a fine technology or a micro machine technology, it is sufficiently possible to fit in a 5 mm square size.

Next, the human body wearing detector will be described.

After the operation of the above-mentioned moisture absorption detector, the presence or absence of wearing is confirmed by a human body wearing detector. A part of the human body, for example, when worn on the earlobe, conduction of the earlobe contact surface,
This is a detector that turns on when there is a temperature, and for example, a commercially available small and thin temperature sensor can be used. It is also possible to compare the amount of conduction by applying ultrasonic waves or a small amount of current instead of the temperature sensor. The temperature sensor is
It has a temperature change film on the inner surface and has a structure that is turned ON when a temperature between 34 ° C. and 40 ° C. is detected in the same manner as a human body temperature. If it is not attached, turn off the power and do not energize. If the wearing of the human body is confirmed and the decrease in temperature is confirmed, the abnormal state of the human body is detected.

Next, a human body abnormality determination detector will be described with reference to FIG.

In the cordless measurement of HP oxygen saturation SaO ₂ , it is assumed that a pulse oximeter used for medical treatment has a cord. (The terminal of the currently used medical pulse oximeter is connected to the CR
Send data to T. 2.) The pulse oximeter is a medical measuring instrument, which should be set by a human at the time of measurement and the measurement switch should be operated intentionally, and is rarely monitored by a normal human being constantly attached to the human body. For example, when the sick person is in a critical state, the monitoring may be continuously performed for 24 hours. However, such a case is rare, and it is necessary to constantly monitor the power supply.

In the human body abnormality judging detector shown in FIG. 4, when necessary conditions are met, the transmission data is automatically transmitted from the human body wearing detector via the input terminals 501 and 502 to the AD converters 503 and 504. To be converted to digital data. When digital data is transmitted from the AD converters 503 and 504 to the light emitting diode 505, the visible light (66
0 nm) 507 and infrared light (940 nm) 508. These lights pass through a part (A1) of a human body such as an earlobe, and are visible light (660 nm) 509 and infrared light (940 nm) 51 reached by the light receiving diode 506.
0 is received. Visible light amount (660 nm) when received
And the current value of the infrared light quantity (940 nm)
When the value of the difference between the current value of the visible light amount (660 nm) and the current value of the infrared light amount (940 nm) is larger than the threshold value 512, the comparator 513 sends a YES signal to the output terminal 515.
Output the output. (The amount of current is digitized by the operation of these signal control circuits, and the oxygen partial pressure in arterial blood: equivalent to 45% of PaO ₂ , HP oxygen saturation Sa using a pulse oximeter or the like.
A value corresponding to a current value of 80% of O ₂ is calculated. 1) Output a digital signal when the amount of current tends to reach HP oxygen saturation SaO ₂ 80%. 1 is output, the signal transmitter operates and the signal b1 (YE
Send S).

That is, a light emitting diode and a light receiving diode using a semiconductor pn junction having a size of about 3 μm already exist. Using these signals, visible light of 660 nm and infrared light of 940 nm are simultaneously emitted from the light emitting diode from the AD-converted signal. Part of the human body (eg earlobe)
Visible light and infrared light that passed through, the visible light passes as it is, and the infrared light is absorbed by hemoglobin in blood,
The infrared light reaching the light receiving diode is reduced. Conversely, humans having abnormalities in the human body have very high infrared light transmittance because blood hemoglobin is reduced. The difference between the oscillation amount of visible light and infrared light emitted from the light emitting diode and the transmittance of the light receiving diode is determined using a subtractor 511, a threshold value 512, and a comparator 513. Comparison value is 80
%, The blood hemoglobin decrease in the human body = the occurrence of cyanosis phenomenon = information obtained by a comparator that can be judged as abnormal human body (0 if it is within the set value of the electric signal, and it is regarded as abnormal if it is outside the range. Occasionally 1: a human body abnormal signal) is generated and a radio wave is transmitted to the wireless device. One of the features is that the signal of the abnormality determination is converted into 1, 0, so that the amount of information is short, and since the determination is simple, the transmission signal is small and the power power is extremely small.

Regarding the size, a circuit for processing an AD converter, a subtractor, a threshold value / comparator in an LSI chip of about 5 mm square can be formed. In order for the light emitting diode and the light receiving diode to be in contact with the front surface and the back surface of the earlobe, respectively, it is desirable that the light emitting diode and the light receiving diode be attached to and integrated with a temperature sensor that detects human wearing.

The subtractor 511 and the comparator 513 are CM-M.
It is characterized in that the light receiving diode 506 is held in the same substrate by being integrated into one chip by the OS LSI. The size is characterized by a human body abnormality detection detector having a size of about one yen coin or smaller. Further, this is a human body abnormality determination detector characterized by resetting 514 at any time when the operating conditions are not met.

The signal b1 transmitted from the signal transmitter is preferentially connected to the nearest home telephone, portable telephone, PHS or the like. Domestic phone / mobile phone / PH receiving signal b1
K such as S is automatically transferred L to 119th. When the signal b1 is received in advance, the home telephone, the mobile telephone, the PHS, etc., need to be automatically transferred to the telephone 119N of the emergency call system (security circuit) O. It is necessary to register so that the telephone number is automatically transmitted.

Next, the tilt detector will be described with reference to FIG. That is, the tilt detector main body 301 is formed of a conductor (copper), and a hole 302 is formed in the tilt detector main body 301 in a conical shape of 45 degrees (90 degrees in cross section) from the center point. Hole 3 of the tilt detector main body 301
Non-metallic part (for example, paper) 30
3,306 are provided and rendered non-conductive. The holes 30 are provided above the non-metallic portions (for example, paper) 303 and 306.
A metal plate (conductive portion) 304 is fixedly attached so as to close the second metal plate 2. The metal plate (conductive portion) 304 is provided with a conductive contact portion 305 for wiring. A conductive contact portion 308 for wiring is also provided on the bottom surface of the tilt detector main body 301. The metal ball 307 is inserted into the hole 302, and when the tilt detector main body 301 falls down by 45 degrees, the gold ball 307 contacts the tilt detector main body 301 and the metal plate 304, and the conductive contact portion 305 is formed. The conductive contact 308 is electrically connected. If there is a re-operation within a certain time by the control circuit 312 including the delay timer, it is automatically cleared. In addition, when there is an intentional operation, the reset can be performed by pressing the reset switch 311. Since the battery 314 is always connected to the control circuit 312, the control circuit 312 is energized and operates when the power switch 313 is turned on. When the conductive contact portion 305 and the conductive contact portion 308 are electrically connected for a predetermined time, the control circuit 312 outputs a
A signal flows to 2 or a3. The size of this sensor is
Sensors of 5-6 mm square are possible. Regarding the thickness, it is possible to create a sensor of about 5 mm. At present, the micro-machine technology has been developed. If the micro-machine technology is used, this sensor is also processed on a silicon wafer. It is feasible.

This switch is used to turn ON when a human body is abnormally determined by the tilt detector using a structure in which the human body falls down and does not operate even after a certain period of time.

This tilt detector has been ultra-miniaturized to a size of 5 mm or less due to the advance of the current micromachine technology. For this reason, as shown in FIG. 1, when the inclination is detected by the inclination detector C, a signal is sent to the human body wearing detector B, and the presence or absence of the wearing is confirmed. Also here, when it is confirmed that the user is wearing the device, it is connected to the human body abnormality determination detector (HP oxygen saturation SaO ₂ measurement in blood) D. The signal is converted into an electric signal by a circuit E such as a subtractor, a signal converter, a signal amplifier, and a comparator and a battery F1 and transmitted to a signal transmitter G. Here, the power for transmission is amplified by the function of the battery F2, and an emergency radio wave is transmitted from a signal transmitter (for example, a small radio transmitter such as a wristwatch-type PHS: a radio). As a result, human information can be automatically connected to a nearby home telephone, mobile phone, PHS, etc. without a code.

The signal operated according to the above procedure is preferentially connected as the signal b1 to the nearest home telephone, mobile phone, PHS, etc., but is automatically transferred if it is not received in the absence. It is transferred to the relatives and relatives of M, such as family and relatives. If contact is still not made, the system will automatically switch to the emergency call system O or 119N for each city volunteer.

With the introduction of the manual switch H, the signal transmitter G
If you are conscious and fall into a hole or get trapped in a toilet, etc., or if you are unable to move due to poor physical condition or encounter an accident and cannot contact the surrounding area, It is a communication switch that can make outgoing calls.

Further, the present invention provides the above-mentioned human body abnormality detecting communication terminal, wherein the tilt detector is moved by the operation of the human body wearing detector and the human body abnormality judging detector, and is reset whenever the operating conditions are not met. Can be.

As for the battery, a 3 V battery is required as a power source for oscillating / controlling each part and performing radio oscillation. As a battery, a button battery (CR2025) 3V or a polymer battery having a size of 5 mm × 10 mm on two sheets can be stacked to 3 V. By bending and processing them, they can be incorporated into small and thin parts. In the case of an oscillation terminal in which the individual sensors of FIGS. 2, 3, and 4 are integrated, the overall size depends on the size of the LSI to be configured, but is assumed to be approximately 10 to 15 mm square. For signal transmission to the radio,
Until the cordless radio is miniaturized, it is attached to a part of the body (for example, a breast pocket or the body of a hearing aid) using wiring.

Next, an application example will be described.

According to the present invention, marketing can be aimed at as a part of ancillary equipment using a current mobile phone or home telephone. In addition, it can be used for versatility as an auxiliary communication terminal for welfare, elderly people, and deaf people. Since the terminal may be miniaturized, it will be possible to incorporate it into earrings and earrings in the future.

Further, since the present invention is intended to be worn on a human body, the following components can be miniaturized by making them into micro machines. Is being introduced. FIG. 5C shows an application example in which a signal transmitter G is attached to the head and a human body abnormality detecting unit Z is attached to the ear, and is incorporated in a part of a decorative article such as a wrist or an arm shown in FIG. Signal transmitter G, human body abnormality detection unit Z. FIG. 5E shows an application example in which a human body abnormality detection unit Z is incorporated in the metal ring of the ring or instead of the stone. FIG.
In (f), it is also possible to insert a line-shaped signal transmitter G or a human body abnormality detecting unit Z into the frame of the glasses.

In the future, depending on the use of the sheet type thin battery, it is possible to insert the signal transmitter G into a child's name tag or name plate as an application example.

Each component can be miniaturized with low energy by forming an LSI circuit.

The battery is assumed to be a thin-film battery or a button battery, or a solar battery. In recent years, accident accumulation type batteries have been actively developed, and as a future application example, a current accumulation type by detecting a small amount of current generated from the human body and self-generating by the wearing person is also possible. For light emitting diodes and light receiving diodes, there are diodes of millimeter size or less, so they can be used as ultra-small components only by the design method.

When the present terminal and the radio wave transmitting circuit are already provided, the present application and the transmitting circuit section of the following application example are wristwatch type PHS.
It becomes cordless by connecting with something like the size.
5 (e) to 5 (f) show an application example. In this case, the main body and the transmission circuit are connected by a cord and used. However, in the future technology of the 21st century, LSI power reduction, ultra-small size, low cost, ultra-fine wiring, etc. It is presumed that the era in which the transmission circuit will become ultra-small due to development is near. Due to such advances in technology, it is highly likely that the transmitting circuit unit will be incorporated into this terminal. In that case, it is convinced that it can be naturally stored in a ring or a piercing as shown in FIG. Now, along with the development of low-power circuits, the ultra-small size of the transmission circuit has been recognized in the development of wristwatch-type PHSs. As an application example, a case where the transmitting circuit section is a transmitting terminal that can be used cordlessly by being incorporated in the transmitter. Only the terminal section is designed to be similar in size to the large type of female earrings and earrings, and to be lighter and smaller (a size that can be built into hearing aids). This is a wireless ultra-compact human-body-worn anomaly detection communication terminal for the purpose of making emergency calls for human-body mounting, with the aim of making the degree of freedom and cordlessness of the human body possible by making the telephone lines of the home and home wireless.

The human body wearing detector may be turned on when the angle of the part that holds the earlobe is set, as well as the body temperature change of the contact part. In order to further improve the accuracy, the current is passed. The case may be set to ON.
In that case, a detector that uses the human body abnormality determination detector together may be used. For example, it is possible to detect a human body wearing in which a change in temperature is confirmed as an amount of current.

As for the method of mounting the human body, application examples 1 to 6 show portions where the signal transmitter G and the human body abnormality detecting section Z can be directly attached to the human body.

Application Example 1 FIG. 5A shows a type that can be hooked from around the ear hole to a tab. In this case, the signal transmitter G is attached to a part of the human body with a cord.

The application example 7 is an application example in the case where the transmitting circuit section is incorporated in the main body terminal.

With these introductions, when an emergency occurs in a place other than indoors, a system that can confirm the location can be incorporated as an application example by using reverse detection, a car navigation system, or a part of a wandering old man search system. It is possible.

Next, an application example of marketing will be described.

2) It can be introduced as a crime prevention measure and an emergency contact terminal.

3) Products can be handled as home medical small system terminal parts.

4) Products can be handled as ancillary services of mobile phones.

5) Built in hearing aids, etc., can be used for people with bad ears.

6) It can be developed as a terminal for preventing accidents of infants and children.

7) Can be considered as part of research on disaster relief and disaster prevention.

[0099]

As described above, according to the present invention, 1) an ultra-compact human-body-abnormality detecting communication terminal that can be always worn on a human body.

2) When an abnormality occurs, the condition of the human body can be automatically detected and the call can be automatically transmitted.

3) When the user falls unconscious, emergency contact can be automatically made.

4) Since there is a manual switch that can intentionally make an emergency contact in case of emergency, if you fall in a closed room or the key is locked from outside,
Emergency contact can be made.

5) In the event of a fall in a river, pool, or bath, it is possible to have a dedicated line that can make an emergency call to 119 by radio waves.

6) When the main body is manufactured from this block diagram, a micro machine is used for the detection unit, a C-MOS technology or an LSI circuit technology is used for the operation circuit / calculation circuit, and a few millimeters or less for the light emitting diode and the light receiving diode. Because of the introduction of current LSI technology and micro-machine technology, a communication terminal that can be worn on the human ear can be made depending on the design of components and circuits.

The present device is an effective means not only for abnormal transmission of a human body but also for a case where a person is trapped in a place isolated by a crime or accident. In particular, stubborn salaried workers and elderly people often fall overtrusting their health too much. In particular, in the case of isolated elderly people, their homes are often closed and communication with the outside is often impossible. A person who is conscious at such times can respond with a security pendant or the like, but at present the stubborn humans do not rely on such things. In such a case, if the consciousness is lost, the situation is that the room is locked and cannot be rescued unless someone comes. In the 21st century, in an aging society, the number of elderly people who perform walking exercises and marathon jogging for health tends to increase. In such a society, those who are running marathons alone can hardly help if they suddenly fall. When such elderly people, stubborn salaried workers, women who are abducted by children or assaulted, etc. are always on hand, it is an effective emergency contact automatic transmission terminal such as early detection, early rescue, early response, etc. Is estimated.
