2. Description of the Related Art In the modern society, which has reached an unprecedented long-lived society, the number of people who need medical maintenance in their daily lives is rapidly increasing. In particular, people with heart disease, diabetes, and cerebrovascular disease always need detailed medical care. For proper medical management, it is essential to monitor physiological and biochemical information in the living body such as body temperature, blood pressure, pulse, blood glucose level in daily life.

However, practicing these measurements in real life not only hinders the social life, but also imposes a heavy burden on the family who assists them, since it requires a considerable amount of labor. In fact, there are few cases where people who have suffered from the above-mentioned systemic diseases can return to society without the need for medical maintenance. In other words, these obstacles to medical management were the most important factor that prevented patients from returning to society.

It is no exaggeration to say that most of the medical management for patients is spent collecting physiological and biochemical data. Therefore, it is very significant as a means to support the rehabilitation of patients with these systemic diseases and to lead a fulfilling family life by making the system for monitoring these biological information small, automated, labor-saving and safer. is there. Various sensors that detect biological information such as blood pressure, pulse rate, body temperature, and blood glucose level have been miniaturized to milli-order and have achieved high accuracy due to the development of microfabrication technology in recent years, and endoscopes for aneurysms and coronary arteries have been realized. It is actually applied to surgery.
Having patients carry these measurement systems all the time, and collecting medical data automatically and continuously must be a great help for detailed medical maintenance and treatment.

[0005]

Nowadays, a living body monitor system using a living body sensor and an IC chip can be downsized in millimeter units. Acceleration, temperature,
Various elements that measure pressure, light, sound, vibration, pH (pH), etc. are miniaturized to the micron level while having high sensitivity performance, and are sophisticated enough to be installed at the tip of an endoscope. ing. Further, semiconductor chips that control these and provide a function of recording various biological information have become small in size and have advanced logic functions due to the development of integrated circuit technology.

Among these, an element called an IC chip has a communication function in combination with an antenna and has already been used for reading and writing personal information by remote control. It is more difficult to forge or modify than the conventional magnetic recording system, and using these IC chips that can apply high security manages medical information of individuals such as AIDS and hepatitis that should not be known to others. It is also useful in the sense.

However, if the patient is to carry the biometric device, the use of the device is a prerequisite for the patient's own voluntary management.

However, in reality, many patients with systemic diseases are in a situation where they cannot manage these devices sufficiently. Therefore, the measures for downsizing and automating the devices reduce the labor for medical management. It is unlikely that it will lead to.
Rather, there is a risk of further disadvantage for the patient from so-called human error such as damage and loss of equipment by the patient, and in addition, there is concern that measures to protect personal information from criminal acts such as theft and unauthorized use are vulnerable. To be seen.

Therefore, as means for solving the above problems, it has been proposed to implant these biometric devices in the body of a patient. That is, by accommodating the electronic devices that form the basis of the above apparatus in the body, it is possible to completely prevent loss, theft, and damage due to human error. If the measuring device in the body continuously records and provides the biological information that is essential for the medical maintenance of the patient for 24 hours, the diagnostic accuracy can be significantly improved, and the detailed medical care in the patient's daily life can be achieved. There is no doubt that it will be extremely useful in supporting the reintegration of patients, as they can practice active care.

However, regarding the implantation of these electronic devices in the body, there are many doubts about their practical use due to various harmful effects, safety concerns, and ethical and ethical reasons.

One of the major factors is that the device implanted in the body is not guaranteed to function normally for a long period of time without any harmful effect on the living body.

A method for directly adhering or embedding a microchip or the like to a tooth, a denture, or a body tissue has been devised as a method for identifying the identity of an individual, and has already been used for the management of pets and livestock. There is.

However, it is undeniable that the methods of indwelling subcutaneously in these examples of use may damage them due to an unexpected external force, or the occlusal force when placed in the oral cavity such as a tooth. In addition, nuclide radiation such as X-rays and electron beams exposed in medical examinations and treatments and MRI
(Electromagnetic resonance tomography equipment) cannot protect electronic devices from strong electromagnetic waves, and damage to integrated circuits and data contained therein cannot be avoided. Is.

Measures for safety are not sufficient.

A microchip having an integrated circuit is easily eroded by blood or tissue fluid in tissues, and saliva or digestive fluid in the teeth, oral cavity or digestive tract with a slight contact with acid or salt contained in food, and its function. Not only loss, but also chromium, arsenic,
In addition to cadmium, heavy metals such as aluminum and copper, which have recently been suspected as the cause of Alzheimer's disease, may be eluted into the living body. Moreover, when the power source necessary for the operation of the microchip is embedded, no consideration has been given to the insulating property so as not to affect nerve tissue and other noxious effects on living tissues and life support devices such as pacemakers.

[0016] As described above, the conventional implantation method in which invasion is unavoidable does not guarantee the reliability and safety for people to accept with peace of mind, and overcomes the organizational obstacles, ethical and moral issues. Was extremely difficult,
Except for medical purposes in serious diseases such as heart disease, cancer, and diabetes, it has been hesitant to embed a biological information monitor device in the body. In particular, due to many concerns regarding protection of privacy and human rights, there are very few examples in which embedding of an information medium such as a certification body into a living body has been put into practical use for humans.

The applicant of the present invention has proposed that an electronic measuring device using an implant body of a dental construction body or an artificial root having a changed missing tooth, which is applied to a tooth that has been inactivated due to caries or the like, after an appropriate endodontic treatment. We have established a method to monitor the patient's biological information by placing it in the body without any adverse effect on the living body.

The greatest merit thereof is that the space created in the process of treating dead teeth is used as the installation space for the biometric instrument, and thus the invasion of the living body cannot be avoided by the conventional method of implanting it in the human body. Can be completely avoided.

If the device is installed by enclosing it in a material having an insulating property and a waterproof property, the electronic device can be protected from saliva and tissue fluid, and the device can be operated safely with no current leakage to living tissue.

If power is supplied in a contactless manner by electromagnetic induction, it can be used semipermanently.

By shielding the periphery of the integrated circuit with a metal crown or the like used in dental prosthesis, durability against chewing and occlusal force can be secured, and the circuit and information data in the IC chip can be obtained from nuclide radiation and electromagnetic waves. Can be protected.

When a breakage occurs, it can be easily removed and re-installed, and unlike the case where it is implanted in the body tissue under the skin, no surgical invasion is required for the living body to remove or replace the device.

We have overcome the conventional problems associated with implanting biometrics and information communication devices into living organisms, and have made the following new measures to safely install them in the oral cavity and use them permanently. .

First of all, the electronic equipment part of the apparatus is supplied by being enclosed in a dental construction body or an implant body having an artificial tooth root. Most of the deactivated teeth that have undergone root canal filling in dentistry function as teeth again, and thus require a dental construction body as a base. Therefore, the tooth substance is not deleted for the purpose of installing the device itself, and the artificial tooth root is routinely used in the dental clinic for the purpose of supplementing the tooth loss. The application of this device does not interfere with normal dental procedures or change the procedure.

Secondly, the electronic device for controlling biometrics / recording and communication is supplied without being harmful to the living body and completely sealed in a material having waterproofness and insulation. These are completely covered with tooth roots whose stability and safety are improved in vivo by endodontic treatment, and crowns made of metal or ceramic, so that saliva in the oral cavity and surrounding blood flow and tissue fluid Completely isolated from. As a result, the device is firmly placed in the oral cavity without any physical or chemical harmful effect on the living body, and provides a stable function semipermanently.

Third, the electronic device does not have its own power source,
Power is supplied from the outside by electromagnetic induction during operation, which minimizes the chance of current generation in the living body and minimizes the effect on other tissues and electronic medical devices.

Fourth, while the part including the integrated circuit of the present device is installed at a position where it can be covered with a dental prosthesis such as a metal crown, the antenna is installed in the tooth root where radio waves reach. As a result, the functions of transmitting and receiving signals and supplying power for operation are ensured while electrically protecting the integrated circuits and the data contained therein from various radiations and electromagnetic waves and protecting them.

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

1 to 7 show a first embodiment of the present invention. In FIG. 2, reference numeral 2 is a dental construction body (also referred to as “implant”), 2a is an anterior tooth construction body, 2
b is a building for molars.

The dental building body 2 uses the crown material and the remaining roots for prosthesis (scalloping) of a crown on a tooth in which the tooth structure of the crown is substantially lost due to a disease such as caries. By firmly fixing, the strength against occlusal force is secured and the masticatory function of the teeth is restored.

Metals such as gold alloys, as well as composite resins, epoxy resins, and dental cements used in the present invention are used as materials in the present clinical practice of dentistry.

As shown in FIGS. 2 and 3, the dental construction 2
In one example of the anterior tooth building 2a and the molar tooth building 2b, the upper structure 2a called the "core" of the upper gingival part is
-1 and 2b-1, and dowels 2a-2 and 2b-2 called "posts" that are installed and fixed in the tooth root.

Although the shape thereof varies depending on the tooth type, it is roughly classified into two types, one for anterior teeth and one for molars.

In the front tooth building body 2a, the upper structure 2
a-1 has a slightly flat and blunt conical shape with a diameter of about 6 mm
~ 2mm, height about 5mm ~ 10mm, dowel 2
a-2 is tapered and has a diameter of about 4 mm to 1 mm and a length of about 5
It has a pin shape of 10 mm to 10 mm.

In the molar body 2b, the upper structure 2b-1 is a turret type having a slightly elliptical seat and a major axis of about 4 mm.
~ 8 mm, height 5 mm ~ 8 mm, dowel 2b-
A plurality of 2 may be provided depending on the number of tooth roots, but the shape and size of each are similar to those for the front tooth portion or slightly shorter.

As shown in FIG. 4, the biometric information measuring / recording / communication device 4 includes a sensor section 6, a control / recording / communication section 8 using an IC chip, and an induction coil section 10 also serving as a communication antenna. Composed of and.

As shown in FIG. 1, the biological information measuring / recording and communication device 4 described above is used, for example, in the front tooth building body 2.
In encapsulating and molding in a, the sensor part 6 is installed everywhere in the anterior tooth construction 2a according to the property and number of sensors used and the measurement purpose. Control / recording and communication unit 8
Is covered with a metal such as the crown prosthesis 14 and is electrically shielded, so that the upper structure 2a called "core" is formed.
-Install in part 1. The induction coil unit 10 is a post that is called a “post” for performing electromagnetic induction and communication with the outside.
-Install in part 2.

The molding method is carried out in accordance with the crown restoration operation in ordinary dental treatment. That is, after taking the impression of the root canal of the tooth to set the dental construction 2 and making a working model with dental plaster, the dental construction 2 suitable for this is made with a wax mold. The process of doing is no different from the method of manufacturing the general dental construction 2.

Next, the wax mold is embedded in a resin molding flask for a denture, and then the wax mold is poured away with hot water to form a mold.
After the biometric information measurement / recording and communication device 4 is further covered with silicon, it is placed in the mold according to the above, and then an epoxy resin that cures at room temperature is poured into the mold and cured.

The biomedical information measuring / recording / communication device 4 is enclosed and molded, for example, the anterior tooth construction 2
a, as shown in FIG. 5, using a dental cement,
Combine with 2.

An impression is taken in this state, and a crown restoration 14 is prepared according to a conventional method as shown in FIG. 6, and then the upper structure 2a-1 of the anterior tooth construction 2a is completely covered. Coalesce.

This method is a method for customizing the dental construction 2 for each tooth, but in dental treatment, a ready-made cast body is frequently used in order to speed up the treatment and save labor. . Therefore, it is also possible to use a ready-made dental cast in which the biological information measuring / recording and communication device 4 is embedded. The method of use is to form the root canal according to the shape of the dental construction 2, set the dental construction 2 using dental cement, and further take an impression to produce a crown prosthesis, It is to be attached to the dental construction 2 and is no different from the conventional crown restoration procedure.

After mounting, power is supplied to the biometric information measuring / recording / communication device 4 by electromagnetic induction, and the control / recording / communication unit 8 using an IC chip or the like is operated by this power supply, and biometric data is supplied. To record.

The control / recording using the IC chip and the recorded contents of the communication unit 8 are protected by the security function, but when the data is read out to the outside, the radio waves transmitted to the surroundings are intercepted and the encryption etc. There is no denying that it could be used to decipher. Therefore, it is desirable to use a communication device capable of ensuring a sharp directivity such as a microwave so as to minimize a leaked radio wave when performing communication.

Next, the operating principle of the biometric information measurement / recording and communication device 4 will be described using a simple example.

As shown in FIG. 7, a resistor 16 and a capacitor 18 are connected in parallel, and an induction coil 20 is connected to the resistor 16 and the capacitor 18 in series to form a closed circuit. .

Then, depending on the resistance value of the resistor 16, the electrostatic capacity of the capacitor 18 and the inductance of the induction coil 20, a current is generated in the circuit due to resonance with respect to a radio wave of a specific frequency.

When a current is generated, a magnetic field fluctuates in the surroundings, and this magnetic field fluctuation is detected using an electric field and a resonance frequency measuring device, such as a dip meter 22, and the resonance frequency of the circuit is contactlessly detected. To measure.

When a thermistor is used as the resistor 16 of the circuit, the temperature of the circuit can be measured in a non-contact manner by detecting the fluctuation of the resonance frequency of the circuit according to the fluctuation of the resistance value due to the temperature change. You can

Further, by applying an acceleration sensor as the resistor 16, it can be used as a sphygmomanometer and an occlusal force meter by applying a pulse meter and a strain gauge, and a capacitor 18
If it is a polymer capacitance change type humidity sensor, it becomes a hygrometer. In the near future, it will be possible to house all sensors in an IC chip to realize multifunctional biometrics.

The basis of the biological information measuring / recording and communication device is physiological information such as body temperature, pulse, blood pressure, and oxygen saturation, as well as blood images, blood sugar, cholesterol, neutral lipids, amino acids, enzymes in tissues, ATP, biochemistry such as antibody titer, electronic sensors for measuring immunological information, IC chip having measurement control logic circuit and readable / writable storage device, and antenna for realizing non-contact communication It is also composed of an electromagnetic induction coil for power supply.

Basically, the feature is that the electronic device and the living body are isolated from each other.
Non-invasive measurable acceleration, pressure, temperature, humidity, light or laser, magnetism, sound wave sensor, etc. are mainly used, but endocrine disease represented by diabetes, leukemia, immune and blood diseases such as AIDS, liver disease, etc. In the case of, the biosensing method in which a bioceramic sensor that directly detects biochemical and immunological information such as blood glucose level, various enzymes and amino acids, electrolytes, antibody titers, etc. is contacted with body tissues from medical benefit. Is also available.

For example, the body temperature is directly measured by placing an element such as a thermistor in the dental construction body. Current,

client) thermistor (NTCCM1005: TDK
Co., Ltd. is supplied as a part having a size of about 1 mm. By using the element alone excluding these packages, it is possible to downsize as a sensor of the micron unit, and it can be accommodated in a dental construction body or an implant body with a margin.

With respect to the pulse rate, the pulse rate is calculated after detecting the vibration and the pressure applied to the tooth due to the pulsation by using the acceleration and pressure sensors. In blood pressure measurement, a phenomenon in which the pulse amplitude fluctuates in the supine position and the standing position depending on the value is used.

That is, the body position is detected by using the fall switch and the hall element, and the pulse amplitude in both body positions is measured by the acceleration sensor, and then the blood pressure value is calculated by the difference calculation.

In addition to this, a method of measuring the strain of the tooth due to the pulse pressure using a strain sensor such as a strain gauge may be used for the blood pressure measurement.

At this time, a microchip size pressure sensor (FPM-30PG: Fujikura Ltd.) in which a piezo-type silicon single crystal semiconductor element is coated with silicon gel, or an acceleration sensor (PKGGS-00LA: in which piezoelectric ceramics are bimorphized) is used. Murata Manufacturing Co., Ltd. etc. can already downsize to a size of 1 cubic mm or less.

Further, a strain gauge, a thermocouple or the like can be accommodated as a biosensor in the dental construction, and a part of these series of microsensors has already been applied to an angioscope.

In the future, in order to measure the blood oxygen saturation, an LED (Light Emittin) assembled with an integrated circuit on a silicon wafer is used.
gDiode) and a photodiode, and a photoelectric sensor (photocoupler, photointerrupter) that irradiates light from inside the tooth to detect blood flow in surrounding tissues as a photoelectric pulse wave, and photoelectric sensors with different light wavelengths are used. Pulse oximetry to calculate the composition ratio of oxyhemoglobin and deoxyhemoglobin is realized by a method using a plurality of.

The humidity sensor is used as a measure for detecting the intrusion of water into the inside of the device, which is a concern when the electronic device is embedded in the living body, and preventing malfunction or failure of the device.
In that case, the polymer resistance change type and polymer capacitance change type humidity sensor (CHS-) has a simple structure and can be easily downsized.
UGS, CHS-MSS: TDK Corp. as a model,
It may be possible to use it by making it micro.

The IC chip for controlling measurement and recording is a monolithic ASIC (Application).
Specific Integrated Circ
It is desirable to manufacture it as a unit, but a plurality of general-purpose operation amplifiers, memories, control and communication chips may be combined.

Considering the shape and size of the dental construction, 1
If it is mounted on each tooth, the die size of a one-chip type IC chip is about 5 mm square. The size of the die when it is attached to the bridge denture (bridge) is not limited to this, and a size of about 5 mm × 30 mm square can be applied. For downsizing, a lead frame or the like is not used for the IC, and the sensor and the induction coil are directly bound and wired.
The IC chip has a program for controlling the sensor, has a function of detecting and recording biological information by giving a command from the outside, and then transmitting the information to the outside through an antenna.

Further, since the IC chip can be supplied with electric power from the outside by electromagnetic induction, there is no problem in its operation even if it is completely embedded in a waterproof and moisture-proof material. Therefore, it can be stably placed even in a water-filled tissue and can be used semipermanently. Since it has a function of reading and writing information, it can store not only biometric information of the patient, but also personal information accompanying it, and by rewriting programs and encryption codes, new functions related to biometric measurement and It is also possible to add a security function that blocks unintended access to the IC chip by the patient. For more complete privacy protection, a function could be provided to erase or re-record the information stored on the IC chip, as required by the patient.

In order to supply power to the electronic device used in the present invention and establish communication, the antenna in the tooth root must have the ability to receive the radio waves transmitted through the soft tissues around the oral cavity and the alveolar bone. .

The antenna has a diameter of 1 mm to 2 mm and a length of 5 m.
Efficient transmission / reception is required with a size of m to 10 mm. Since the communication antenna secures sufficient sensitivity and also has the function of an induction coil, in addition to a winding type coil with a core of ferrite or alumina to secure the air core or permeability, a laminated type or thin film Molded coil inductors can also be used. In particular, among these, small signal coils and chip inductors have been dramatically miniaturized in mobile terminals and the like, and some of them have a size of 1 cubic mm or less.

The shape of the antenna installed in the space inside the tooth root is preferably a cylindrical shape having a diameter of 1 mm to 3 mm and a length of 5 mm to 8 mm, and it seems that this size can be easily realized in the current state of the art.

For example, even though the coil above the rotary head in a video recorder is much smaller than the above size, high-speed friction (5 m / s to 6 m / s) with a video tape in an environment of several thousand revolutions per minute. ) Has a durability that can also correspond to.

When a microwave or the like is used for communication, a material having high impedance such as ceramic can be used as the antenna. It is also possible to use bioceramics such as hydroxyapatite, aluminas, and titanium oxide, which have high biocompatibility, as antennas.
In that case, the artificial tooth root (fixture) itself in the implant could be used as an antenna.

The biological information measuring / recording and communication device constructed according to the present invention basically has a sensor section, a control
It consists of three parts: a recording / communication section and an induction coil section that also serves as a communication antenna. As is clear from observing the inside of terminal devices such as mobile phones, the input keyboard, display device and built-in battery occupy most of the volume, while the central part of the terminal is the CPU (central processing unit). It is integrated into less than 10 chips such as processing equipment) and memory, and is surprisingly miniaturized. The present invention is ASI
If it is manufactured in C, it is possible to make a monolithic integrated circuit in which the sensor unit and the communication unit are integrated.

The present invention does not use any parts having a large volume or weight such as an input key, a monitor, and a battery, and adopts only an electronic device which can be easily miniaturized by the technology currently put into practical use. Since it can be implemented immediately without making a new investment, the benefits and cost performance for penetrating the present invention into the medical market are sufficiently secured.

However, the needs from the medical field in the present invention will require further improvement in function and performance. Above all, the increase in the amount of information to be stored is the first decision. For example, the communication type non-contact IC tag (VS-1: Shinwa Engineering Co., Ltd.) that is already sold has a diameter of 5 mm.
A 2 Kbyte memory is mounted on a small ball of mm. Although this amount of information is comparable to a document of about one A4 page, there is a feeling that the recording of biometric information in the present invention is somewhat unsatisfactory.

Currently, the memory capacity of a memory used as a memory element of a personal computer is remarkably increasing, and it has already been increased to 1M.
More than a bit of products are appearing in the market. In recording the biometric information in the present invention, by always adopting a new memory of that era, it will be possible to meet the needs that require more programmatic and complicated functions that will be required in the future.

Battery downsizing is progressing dramatically today, and miniaturization will be achieved in the near future.

In the present invention, since the battery can be stored inside the dental construction which is an insulator so that the electric current does not leak to the living tissue, in that case, the self-sustained operation by the built-in power source is also possible. These batteries must be rechargeable secondary batteries because they cannot be replaced for a long period of time once they are attached to a living body, but since the power supply is secured, the device can always operate without relying on an external power supply. Its convenience is greatly improved.

For example, an alarm can be issued when the patient's condition suddenly changes, and it can be used as a method for finding a wandering elderly person. In a distress, it may play a decisive role in dividing the light and shade of rescue. Normally, charging is performed by an external power source, but by separately providing a power generating device such as a piezoelectric element or an inductor in the oral cavity, it is possible to perform an independent operation by supplying power using pressure or acceleration due to occlusal or chewing force.

In order to stably install the above-mentioned biometric information measuring / recording and communication device in the oral cavity of a patient, when molding these into the shape of a dental construction body, materials that satisfy the following conditions are used. There is a need. That is, 1. 1. Does not affect the electronic device to be enclosed. 2. It has sufficient strength as a dental construction. 3. It has waterproof and moisture-proof ability. 4. It has no harmful effect on the living body. 5. Transmit radio waves, With an electrical insulator, and so on. Dental filling materials such as composite resins, which have already been widely used in dental clinic, generally meet the above-mentioned conditions, and it is possible to use these to enclose the device and shape it as a construction body. Of these, the epoxy resin (transparent epoxy GM-9002: Brennie Giken Co., Ltd.) has excellent electrical insulation and strength, and can be molded at room temperature. It seems to be most suitable as a matrix.

However, when these are used as the material for the dental construction, they are repeatedly stressed by the occlusal force, so that a material having poor flexibility may crack during long-term use. At this time, from the viewpoint of preventing damage to the electronic device caused by minute leakage of water, when molding the device, the electronic device is thinly coated with a flexible material such as silicon, and then an epoxy resin having strength is used. It is also necessary to consider the need to secure a higher degree of moisture-proofing and waterproofing capability that withstands long-term use by adopting a so-called laminated structure that is encapsulated and molded with a material such as resin or composite resin.

The installation of this device does not target vital teeth having pulp nerves which are extremely sensitive to electric current, and the pulp is lost due to the etiology of caries, periodontal disease and dental prosthesis. Target deactivated teeth.

When the tooth collapses once due to caries or the like and the pulp is affected, the tooth itself becomes inactivated by performing endodontic therapy, but it can be preserved through the cementum on the root surface and is permanently preserved. It is possible to maintain

The space of the root canal and pulp cavity hollowed out by the endodontic procedure is replaced by a dental construction for later restoration of the crown. This dental construction has a volume sufficient to hold an IC chip and an antenna, which are a die size of several millimeters square.

For a tooth subjected to endodontic treatment, in order to prevent secondary caries that may occur after the treatment, a treatment for completely blocking the invasion of tissue fluid around the tooth and saliva into the tooth is performed. It is unlikely that moisture will enter the part of the building for construction, and the use of a waterproof material as the material for the dental construction may cause deterioration of the device due to corrosion of the sensor and IC chip. Almost nothing. Even if the device fails, it can be easily removed and replaced by replacing the artificial teeth.

The tooth on which the biological information measuring device is present can be chewed in the oral cavity by covering the tooth crown with ceramics and a metal crown based on a conventional restoration procedure.
Moreover, no accident such as breakage occurs.

Further, by coating the periphery of the IC chip with metal, the IC chip can be protected from exposure to various radiations and electromagnetic waves used in medical examination such as X-rays and MRI (nuclear magnetic resonance).

The head and neck having the oral cavity is an object that is always carefully protected against impact and invasion as compared to the extremities and trunk, and is a stable environment in terms of temperature and chemical. Therefore, if it is sufficiently protected from external force due to saliva and occlusion, it can be said that it is the most suitable place in the human body for the placement of the electronic device.

At present, a method of engraving a patient name on a denture using a microchip has been proposed in the oral cavity. It may not be possible to use this for biometrics, but since the denture is originally attached and removed,
As with other handheld devices, it may require patient self-management.

There are many cases in which many victims lose their dentures after every major earthquake.

In the present invention, by utilizing the deactivated tooth,
It is epoch-making in that it realizes complete integration between the electronic measuring device and the human body and completely automates the measurement and recording of biological information.
The safe management of information is promised by adopting an IC chip for recording. Above all, electronic devices such as sensors and IC chips, which are originally foreign substances to the living body, are completely enclosed in the dental construction body and attached to the deactivated tooth, and by the strictness of covering with a metal or ceramic crown, originally, Sufficient safety is ensured against unavoidable foreign body reactions when implanted in living tissues and leakage of metals and chemicals that are not welcomed by living organisms.

The installation site of the biological information measuring / recording and communication device in the present invention is a useless space created after the treatment of the dead tooth. Therefore, there is no new invasion or pain to the living body due to the installation of the device. Moreover, it is safe and reliable, has high convenience for maintaining health, and does not cause any ethical or ethical problems like other implantable medical devices. It is essentially different from a medical device, such as a cardiac pacemaker, which is implanted in the living body due to unavoidable circumstances.

From this point of view, it is expected that the present invention will contribute to the practice of amenity medicine in a new era and will be widely used as a future health care tool for supporting the health and social activities of patients. it can.

FIG. 8 shows a second embodiment of the present invention. In the second embodiment, the portions having the same functions as those of the first embodiment will be described with the same reference numerals.

The feature of the second embodiment is that the information terminal means 32 is provided for the biological information measuring / recording and communication device 4 enclosed inside the dental building body 2, for example, the anterior tooth building body 2a. Is connected, and the information terminal means 32 controls the measurement / recording of biological information and the information input / output of the communication device 4.

That is, as shown in FIG. 8, the biometric information measuring / recording / communication device 4 includes a sensor unit 6, a control / recording / communication unit 8 using an IC chip or the like, and a guidance serving as a communication antenna. It is composed of the coil portion 10.

The information terminal means 32 has a two-way communication function, and is, for example, a portable information terminal device (also referred to as "portable communicator" or "PDA terminal device") 34 or a fixed information terminal. The device (also referred to as “fixed communicator”) 36.

More specifically, the portable information terminal device 34
As shown in FIG. 8, a main body 34-1 formed to have a passport size so as to be portable, and a main body 34-
1 has a display screen section 34-2 and a plurality of button operation sections 34-3 for controlling information input / output.

The fixed type information terminal device 36 includes a main body portion 36-1 made of a personal computer, a display portion 36-2 for display, a keyboard portion 36-3 for input / output operation and a mouse portion 36-4. Have and.

In addition, the information terminal means 32 regularly reads and writes the biometric information measuring / recording and communication device 4 to constantly monitor the biometric information such as the body temperature, blood pressure and pulse pattern of the person. It is a thing.

A specific example will be described below.

The biological information measuring / recording and communication device 4 enclosed in the dental building 2, for example, the anterior tooth building 2a functions as a biological sensor and communicates with the biological information measuring / recording and communication device 4. By performing the above, the information terminal unit 32 including the portable information terminal device 34 and the fixed information terminal device 36 acquires the biological information from the biological information measurement / recording and communication device 4.

The portable information terminal 34 can always acquire and record biometric information by being carried by the wearer of the biometric information measuring / recording and communication device 4 which is a biometric sensor.

On the other hand, the fixed type information terminal device 36 is used by a doctor / dentist when the wearer does not use the portable information terminal device 34 for some reason, for example, when going to bed or bathing, or when going to the hospital or hospitalization. It is used when acquiring and describing (updating) appropriate information on the fixed type information terminal device 36 under medical management by an appropriate organization (medical institution, fire department, police, legal affairs, etc.).

The measurement functions provided in the biological information measuring / recording and communication device 4 include acceleration, temperature, light, pressure, and posture (positioning), which are currently being miniaturized.
It is possible to incorporate sensors for magnetism and the like.

For example, if a temperature sensor is installed, it is possible to constantly monitor body temperature, and if a pressure sensor and an acceleration sensor are used, it is possible to constantly monitor blood pressure and pulse rate. The data can be used for physical condition management.

Further, the present invention is installed inside the dental construction 2 in the oral cavity, for example, the front tooth construction 2a,
By using the acceleration sensor, it is possible to apply to an alarm system that transmits an injury to a human body as an alarm by detecting an abnormal impact on the head that may occur in an accident or crime that is unfortunately encountered.

Regarding the application to these crisis management, considering that there are many cases in which the human body often accepts a considerable shock even in a situation in which the limbs and body are not abnormal, such as during sports, This is a function unique to the above-mentioned sensor being installed on the head, and may have the possibility of realizing an exclusive body management function compared to other biosensor usage methods installed on a site other than the head. is doing.

Further, in the human body, the head is a subject to be particularly protected, and the loss of blood pressure and pulse in it and the vibrations and shocks far exceeding the average in life cause disorders of the central nervous system, which is the seat of the life center. It is directly connected to.

Therefore, the biometric information measuring system in the oral cavity can provide a security function most relevant to the safety of life.

For example, the health management of the elderly living alone is a major issue in the advanced nations that are accelerating the aging society.

It is completely impossible to force the elderly to carry out physical management such as carrying out an electrocardiogram, a thermometer, a respiratory sensor, a blood pressure monitor, etc., such as those in a central control unit (ICU) of a hospital and constantly monitoring them. The biological information measuring / recording and communication device 4 and the portable information terminal 34 enclosed in the dental building 2, for example, the anterior tooth building 2a are wearable, and most of the body management functions are worn by the wearer. It is possible to provide without stress.

That is, the blood pressure is measured by the pressure sensor, the pulse is measured by the acceleration sensor, the body temperature is measured by the temperature sensor, and the red and near infrared light sources are secured by the light-emitting diode or the like to detect the light sensor. Measurement of blood oxygen saturation can be realized.

The information terminal means 32, in particular the portable information terminal device 34, can constantly monitor the attached sensor and monitor the biological information to detect a sudden change in physical condition and issue an alarm.

However, in these implementations, for example, in the case of a sudden change in physical condition, the change in blood pressure occurs due to the time when the changes in pulse rate and blood pressure are detected and due to exercise or heavy work in normal life. It is necessary to distinguish it from the case.

Therefore, when an abnormal value is detected in the pulse and blood pressure sensors, the state of the posture sensor is simultaneously monitored.

That is, in most cases of sudden changes in physical condition, the posture of the sensor wearer is in a continuous supine or prone posture, while on the other hand, the posture of the wearer is elevated when blood pressure / pulse rises due to exercise or work load. Is standing. Therefore, when an increase in the pulse / blood pressure of the sensor wearer is detected, by simultaneously detecting whether or not the posture is in the supine position, the information terminal means 32, particularly the portable information terminal device 34 is detected.
It is possible to determine the emergency situation of the sensor wearer with high accuracy and automatically issue an alarm.

However, when the present invention is constantly applied in daily life as described above, the biological information measuring / recording and communication device 4 to be installed in the oral cavity and the information for managing / operating it. The terminal means 32, especially the portable information terminal device 34, must always cooperate with each other.

It is not necessary to carry the portable information terminal 34 if the biometric information recording according to the present invention is carried out at any time as needed, but it is possible to have a disease that seriously interferes with the maintenance of the body. If it is desirable to be always under medical control, it is necessary to carry the portable information terminal 34 at all times. For that purpose, the portable information terminal 3
Reference numeral 4 constantly monitors the operation of the biometric information acquisition function so that the biometric information recording device is constantly linked.

For example, when changing the clothes or taking a bath, the portable information terminal 34 is sometimes removed from the wearer and the acquisition of biometric information may be interrupted. When biometric information acquisition by the model information terminal device 34 is not resumed, it is desirable that the portable information terminal device 34 has a security function of issuing an alarm.

These systems can be used as a useful security tool for alerting a normal person to an emergency situation. For example, the problem of bullying by school children and students is a major social problem that has long been desired to be solved, but the major factor that has prevented the solution is the fact that victims are bullying. It is a case of hesitating to announce.

Victims hesitate to announce that they are: first, in an environment where bullying is easily concealed, that is, in a place where there is little chance of witnessing a third party. This is because it is difficult to prove, and thirdly, the voluntary indictment of the victim is blocked by the perpetrator.

The biometric information measuring / recording and communication device 4, which is a biometric information measuring system installed in the oral cavity, has a harmful effect due to violence such as shock and pulse / blood pressure update caused by injury to the victim. The situation is recorded at the same time as it detects the alarm in real time and gives an alarm.

As a result, since the notification of the damage caused by bullying is not disturbed by the intent of the perpetrator, it is surely notified to the appropriate organization, so that the case can be promptly and surely investigated.

These systems will be a great deterrent to violent acts of school children and students, and if their use is expanded, they can be effective as one of the means for realizing a safer social environment.

9 to 12 show a third embodiment of the present invention.

A feature of the third embodiment is that a biometric information measuring / recording and communication device 42 applied to a security tool based on biometric dynamism pattern authentication is disclosed.

That is, the biometric information measurement / recording and communication device 42 is a biometric sensor installed as the dental construction 2, and the biometric information of the wearer can be constantly recorded using the biometric sensor.

Such information includes pulse, blood pressure, body temperature, blood oxygen saturation and the like.

As an example thereof, according to the knowledge of the third embodiment based on the operation principle, the pulse wave can be acquired by using the optical sensor installed in the oral cavity.

Here, a method for obtaining a pulse wave based on the optical detection method from the dental pulp will be disclosed.

For example, as shown in FIG. 9, a photodiode 46 for detecting light and a light emitting diode (also referred to as “LED”) 48 serving as a light source are mounted on the upper anterior tooth 44 by a holder 50.

At this time, from the light emitting diode 48 mounted on the lingual side of the upper jaw anterior tooth 44 to 568, 660, and 94.
After irradiating the tongue side surface of the maxillary anterior tooth 44 with 0 nm monochromatic light, the light transmitted through the maxillary anterior tooth 44 is applied to the photodiode
To detect.

Further, as shown in FIG. 10, there is also a method of attaching a photodiode 46 for detecting light and an optical fiber 52 for introducing a light source to the upper anterior tooth 44 by a holder 50.

Then, through the optical fiber 52, visible light, near-infrared light, and near-ultraviolet light having an arbitrary wavelength is irradiated from the lingual side of the upper jaw anterior tooth 44, and then the light transmitted through the upper jaw anterior tooth 44 is detected by the photodiode 46. To do.

At this time, the irradiation light and the photodiode 4
The characteristics of 6 need to be adjusted as needed according to the type of biometric information to be retrieved, but the light source is set to an effective value of about 100 μ (micron) W, which is a level of intensity that does not have a harmful effect on the living body.

The waveform shown in FIG. 11 is obtained by irradiating the maxillary anterior tooth 44 with green light of 568 nm using the light emitting diode 48 as a light source and then detecting the transmitted light.

The upper part (attached to "TLP") in the left and right waveforms in FIG. 11 is the light intensity transmitted through the upper anterior teeth 44, and the lower part is the electrocardiogram (attached to "ECG") of the subject to be measured.

The output due to the light transmitted through the upper anterior teeth 44 is
It changes in homology with the subject's pulse. This reflects the fluctuation of the pulp blood flow of the maxillary anterior tooth 44 due to the pulse,
Transmitted Light Pulse Wave (Transmitted Light)
This is called photoplethysmography).

In such a case, light in the visible short wavelength region, which has a high absorption characteristic for blood hemoglobin, is used so as to easily reflect the blood flow volume.

Further, in order to extract the transmitted light limited to only the tooth, it is effective to opaque or mask other than the tooth to be measured so as to suppress the mixing of light from other than the object to be measured.

The graph waveform on the right side of FIG. 11 is the result of measurement using a black rubber dam sheet that masks other than the tooth to be measured, and the amplitude of the obtained waveform is greatly reduced compared to the left side. It is shown.

This indicates that even if light is introduced from the tooth toward the surrounding tissue, the pulse wave can be detected from the light propagated to the surrounding tissue.

FIG. 12 shows 660, 810, and 940.
It is a transmitted light photoelectric pulse wave targeting a tooth with a light source of nm, and a pulse wave can be obtained when a light source of 810 or 940 nm is used, but a pulse wave cannot be extracted when a light source of 660 nm is used. It is understood that it is necessary to select an appropriate light source depending on the search target.

Minute photocoupling has already been put into practical use in a semiconductor relay or other integrated circuit in which a system for detecting light and detecting the light and converting it into an electrical output is built.

It is easy to apply these to the IC chip of the biometric information measuring / recording / communication device 42 of the third embodiment, and the biometric information measuring / recording / communication device 42 is applied.
It is also possible to add a photoelectric pulse wave measurement function to.

In addition to the above, a method for detecting local vibration caused by a pulsation by an acceleration sensor and a method for detecting local tissue pressure due to blood pressure have been established for pulse measurement.

That is, in the biological information measuring system according to the third embodiment, that is, the biological information measuring / recording and communication device 42, the vital signs of the living body are not limited to simple numerical data such as the pulse rate and blood pressure, but to the pulse wave. It is possible to obtain a two-dimensional image such as.

The function of acquiring a human vital sign as a fine waveform image is the medical management for maintaining the physical health such as the diagnosis of the cardiovascular function by the electrocardiogram waveform, and the security for transmitting the physical danger of the person. Not only can it be used in the system, but it can also be used as a highly accurate personal identification means.

In such a system, of course, the identity of the wearer and medical personal information, etc. are stored in case of emergency such as personnel loss of the wearer, and the system itself is a function of identification. There is a high possibility that a case will be secured.

Because the biometric information measuring / recording and communication device 42 is different from a credit card or a license,
Because it is embedded in the teeth, the risk of theft or loss is extremely low, and it has high reliability as a means of identification.

However, as in the case of copying and forgery of card data due to skimming, which is rapidly increasing in credit card crimes in recent years, any unauthorized access to the IC chip of the biometric information measurement / recording and communication device 42 should be performed. Therefore, the internal personal information may be copied and the identification function may not be forged.

Therefore, when an authentication function is added to the biological information measuring / recording / communication device 42 for use, the fact that the shape of the pulse wave when the human is at rest is almost constant is noted, and After recording and generating a pattern for each individual, it is registered as a data pace.

When the individual is authenticated, the pulse wave pattern acquired from the wearer is collated with the pattern registered in the database in addition to the recorded information of the IC card of the biological information measurement / recording and communication device 42. .

By so doing, it is possible to provide a biometric dynamism pattern authentication function.

The first characteristic of this vital pattern authentication is the authorization with a focus on "social life".

That is, it is possible to completely prevent the impersonation of others by duplication / counterfeiting of a card as seen in a credit card crime, and when the wearer has a serious physical disorder, for example, the wearer dies. By doing so, when the biological information measuring / recording / communication device 42 cannot detect the vital sign, the function as the authentication body can be lost at that time.

This is particularly effective in a field requiring high security. As an example, it can be used to deter aircraft hijacking crimes.

First, the biological information measuring / recording / communication device 42 is mounted in the pilot's oral cavity for operation, and the biological information measuring / recording / communication device 42 is authenticated on the aircraft side so that the pilot can freely operate. The function that enables various controls is added in advance.

It should be noted that even when the aircraft is in flight, the biological information measuring / recording and communication device 4 is provided around the cockpit.
Unless 2 is functioning as an authenticator, the system will not allow free operation.

If the hijacker removes the pilots from the cockpit, or if the pilot dies in the worst case, the aircraft cannot authenticate the biological information measurement / recording and communication device 42, and at that time. The aircraft is forced to become an autopilot.

During autopilot, the vehicle keeps turning around the nearest airport until the minimum amount of fuel required for landing is reached. By programming to perform automatic landings, hijackers can be prevented from flying the aircraft to their destination.

Such an advanced security function is unique to an authentication body such as the biological information measuring / recording / communication device 42 that recognizes a vital sign of a biological body, and is, so to speak, an ultimate personal authentication system. Is possible.

The present invention is not limited to the first to third embodiments described above, and various application modifications are possible.

For example, the biometric information measuring / recording and communication devices disclosed in the first to third embodiments of the present invention include not only the biometric information of the wearer but also various personal information necessary for medical management. Although it has a function to record the user's privacy, it is extremely useful that such information is always with the wearer when dealing with an emergency such as a sudden change in physical condition. It has the potential to be plagiarized by some other person. In some cases, tampering with the wearer's confidence may occur.

Therefore, when personal information is recorded in the biometric information measuring / recording and communication device, security measures such as encryption may be applied.

That is, the data to be protected by encryption is input from the wearer's name, address, date of birth, contact information, insurance policy number and symbol, blood type, and other necessary information from a medical institution. Includes information related to medical treatment of the wearer (medical history, progress, prescription, items to be communicated to patients, etc.).

As the encryption method, the use of common key encryption, which is used as a general encryption method, is considered, but the common key encryption method has room for data alteration by the wearer. .

Therefore, when a medical institution introduces a wearer to another hospital and records medical information in a biological information measurement / recording and communication device, a public key is used as a safer encryption method. It is desirable to use an encryption method.

In this case, the medical institution making the inquiry encrypts the inquired items with the public key of the referral destination, and decrypts the data with the private key of the medical institution of the referral destination.

Thus, when personal information is recorded in the biometric information measurement / recording and communication device, sufficient security measures can be taken by encryption.

[0173] Further, it is possible to install the biometric information measuring / recording and communication device disclosed in the first to third embodiments of the present invention in the orthodontic bracket and install it in the oral cavity. .

That is, the biological information measuring / recording and communication device is exposed in the oral cavity.

By the way, since the biological information measuring / recording and communication device can be exposed in the oral cavity, a pH (pH) sensor can be incorporated as a sensor,
With this pH sensor, it is possible to realize a caries prevention system by measuring the acidity of saliva in the oral cavity, and a salt intake monitor by measuring the electrical resistance of the ingested food. It can contribute to management and is practically advantageous.

In the biological information measuring / recording / communication device exposed in the oral cavity, an aerial (antenna) for communicating with the outside is formed into a loop coil shape covering the outer periphery of the biological information measuring / recording / communication device. , Or the stainless wire used for the orthodontic bracket can be used together as an aerial, which facilitates the production.
