Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a biological information measurement / recording / communication device using a dental structure and an information control method for controlling information input / output of the device, and more particularly to a minute biological information measurement sensor and its control / recording / communication function. An IC chip and an antenna that also serves as an electromagnetic induction coil are encapsulated in a dental structure used in dental treatment, and attached to inactivated teeth or alveolar bone based on conventional dental treatment. A medical measuring instrument that automatically and continuously collects medical data necessary for maintaining the health of a patient by integrating with the human body without causing any new invasion or injury. And an information communication apparatus and an information control method for controlling information input / output of the apparatus.
[0002]
[Prior art]
In today's society, which is facing an unprecedented long-life 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 disorders always require meticulous medical care. For appropriate medical management, it is indispensable to monitor physiological and biochemical information in the living body such as body temperature, blood pressure, pulse, blood glucose level in daily life.
[0003]
However, practicing these measurements in real life involves considerable labor, which not only interferes with social life, but also imposes a heavy burden on the family who assists them. In fact, there are few cases where people who have suffered from systemic illnesses such as those described above can return to society without the need for medical maintenance. In other words, the stumbling blocks of these medical managements were the biggest factors that hindered patients' return to society.
[0004]
It is no exaggeration to say that the majority of medical management for patients is spent collecting physiological and biochemical data. Therefore, the miniaturization, automation, and labor saving of these biometric information monitoring systems have great significance as a means to support the rehabilitation of patients with these systemic diseases and lead a fulfilling family life. is there. Various sensors that detect biological information such as blood pressure, pulse, body temperature, blood glucose level, etc., have been miniaturized to high accuracy due to the recent development of microfabrication technology, and have achieved high accuracy. Endoscopes for aneurysms and coronary arteries It is actually applied to surgery. Having these measurement systems always carried by the patient and automatically and continuously collecting medical data must be a great help for meticulous medical maintenance and treatment.
[0005]
[Problems to be solved by the invention]
Today, a biological monitor system using a biological sensor and an IC chip can be downsized in millimeters. Various elements that measure acceleration, temperature, pressure, light, sound, vibration, pH, etc. are miniaturized in micron units and have high sensitivity performance, and are installed at the tip of the endoscope. It is so sophisticated. In addition, the semiconductor chip that provides the function of recording various biological information by controlling them has become small in size and has advanced logic functions due to the development of integrated circuit technology.
[0006]
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. Use of these IC chips, which are difficult to counterfeit and modify compared to conventional magnetic recording methods and can apply advanced security, manages medical information of individuals who do not want others to know, such as AIDS and hepatitis It is also useful in terms of meaning.
[0007]
However, if the patient is to carry the biometric device, the use of the biometric device is a prerequisite for the patient's own management.
[0008]
However, in reality, many patients with systemic illnesses are in a situation where they cannot manage these devices sufficiently, and measures that only reduce the size of the device or automate them will reduce the labor for medical management. Is hard to think. Rather, there is a risk of further disadvantage to the patient from so-called human errors such as damage or loss of equipment by the patient, and in addition, the measures to protect personal information from criminal acts such as theft and unauthorized use are also vulnerable. Be seen.
[0009]
Therefore, as a means for solving the above-described problems, it has been proposed to implant these biological measurement devices in a patient's body. That is, by accommodating the electronic devices that form the basis of the above apparatus in the body, it is possible to completely prevent damage due to loss, theft and human error. If the measurement device in the body records and provides the vital information that is indispensable for the medical maintenance of the patient 24 hours a day, the accuracy of diagnosis can be greatly improved, and meticulous medicine in the patient's daily life. There is no doubt that it can be extremely useful in helping patients rehabilitate because of the ability to practice their care.
[0010]
However, regarding the implantation in the body of these electronic devices and the like, there are many doubts about their practical use due to various adverse effects and safety concerns, as well as ethical and moral reasons.
[0011]
One of the major factors is that a device implanted in the body cannot be guaranteed to function normally for a long period of time without causing any harmful effects on the living body.
[0012]
In the past, as a method of identifying an individual's identity, a method of directly bonding or embedding a microchip or the like into teeth, dentures, or body tissues has been devised and has already been used for the management of pets and livestock.
[0013]
However, there is a risk that these methods may be damaged by an unexpected external force in the case of being placed under the skin or the like, and when they are installed in an oral cavity such as a tooth due to an occlusal force. In addition, electronic devices cannot be protected from radionuclides such as X-rays and electron beams exposed to medical examinations and treatments, and strong electromagnetic waves from MRI (nuclear magnetic resonance tomography), and are included in integrated circuits and the like. Problems of maintenance and protection of the device are still unsolved.
[0014]
Safety measures are not enough.
[0015]
Microchips with integrated circuits are easily eroded and lose their function in blood and tissue fluids in tissues, and in the teeth, oral cavity and digestive tract with a slight touch of saliva, digestive fluids and food acids and salts. In addition, chromium, arsenic, cadmium, and other heavy metals such as aluminum and copper, which have recently been suspected of causing Alzheimer's disease, may be dissolved in the living body, including the semiconductor elements and the like in integrated circuits. Moreover, when embedding a power source necessary for the operation of the microchip, no consideration has been given to insulative effects such as nerve stimulation on living tissues and life support devices such as pacemakers.
[0016]
The conventional implantation methods that cannot avoid invasion are not reliable and safe for people to accept with peace of mind, and it is extremely difficult to overcome the tissue damage, ethical and moral issues. Therefore, except for the medical purpose in serious diseases such as heart disease, cancer, and diabetes, it was inevitable to embed a biological information monitoring device in the body. In particular, there have been very few examples in which embedding of information media such as certification bodies into a living body has been put to practical use due to numerous concerns regarding privacy protection and human rights.
[0017]
The patent applicant of the present invention uses an in-vivo electronic measurement device that uses a dental structure or an artificial root implant that changes after a defective endodontic treatment applied to a tooth that has been inactivated by caries or the like. We have established a method for monitoring the patient's biological information without any adverse effects on the living body.
[0018]
The biggest advantage is that the space created during the treatment process of inactivated teeth is used as the installation space for biomedical equipment, so that the invasion of the living body that could not be avoided by the conventional implantation method in the human body is completely achieved. It can be avoided.
[0019]
If the device is enclosed in an insulating and waterproof material, the electronic device can be protected from saliva and tissue fluid, and the device can be operated safely without any current leakage to the living tissue.
[0020]
Semi-permanent use is possible if power is supplied in a non-contact manner by electromagnetic induction.
[0021]
Shielding the periphery of the integrated circuit with a metal crown used for dental prosthesis, ensuring durability against mastication and occlusal force, and protecting the circuit and information data in the IC chip from nuclide radiation and electromagnetic waves Can do.
[0022]
When it is damaged, it can be easily removed and re-installed, and unlike the case where it is implanted in a subcutaneous body tissue, no surgical invasion is required to remove or replace the device.
[0023]
We overcame the conventional problems associated with biometric measurement and information communication device implantation, and made the following new measures to safely install and permanently use them in the oral cavity.
[0024]
First, the electronic device portion of the apparatus is supplied by being enclosed in a dental structure or an implant body having an artificial tooth root. Since most of the inactivated teeth that have been filled with root canals in dentistry function as teeth again, a dental structure as a base is required. Therefore, there is no deletion of the tooth for the purpose of installing the device itself, and the artificial tooth root is used routinely in dental clinics for the purpose of compensating for tooth loss. The application of this device does not interfere with normal dental procedures or change the procedure.
[0025]
Secondly, the electronic equipment that controls biometric measurement / recording and communication is supplied without being harmful to the living body and completely enclosed in a waterproof and insulating material. These are completely covered with dental roots that have been improved in vivo stability and safety by endodontic treatment and crowns made of metal, ceramic, etc. Completely isolated from. As a result, the device is firmly placed in the oral cavity without causing any physical or chemical harm to the living body, and provides a semipermanently stable function.
[0026]
Third, the electronic device does not have its own power source, and power is supplied from the outside during operation by electromagnetic induction to minimize the chance of current generation in the living body, and to other tissues and electronic medical devices Minimize the impact of.
[0027]
Fourth, the part of the apparatus including the integrated circuit is installed at a position where it can be covered with a dental prosthesis such as a metal crown, while the antenna is installed in the root of the radio wave. This ensures the function of transmitting and receiving signals and supplying power for operation while electrically shielding and protecting the integrated circuit and data contained therein from various types of radiation and electromagnetic waves.
[0028]

[0029]

[0030]
DETAILED DESCRIPTION OF THE INVENTION
By inventing as described above, when molding a dental structure, a biometric information measurement / recording and communication device is enclosed inside, and the biometric information is measured by the function of this biometric information measurement / recording and communication device. At the same time, the measurement result and various information associated with the measurement result are stored, and the stored contents are transmitted to the outside.
[0031]
In addition, the communication function is controlled so as to fulfill the input of necessary information to the biometric information measurement / recording and the recording function of the communication device and the output of the information stored by the recording function by the control signal from the information terminal means.
[0032]
【Example】
Embodiments of the present invention will be described below in detail with reference to the drawings.
[0033]
1 to 7 show a first embodiment of the present invention. In FIG. 2, 2 is a dental structure (also referred to as “implant”), 2 a is an anterior tooth structure, and 2 b is a molar structure.
[0034]
The dental structure 2 firmly fixes the crown material and the remaining root when a dental crown is prosthetic to a tooth having a substantial defect in the dental crown due to a disease such as caries. By doing so, the strength against the occlusal force is secured and the masticatory function of the teeth is restored.
[0035]
In the current dental practice, metals such as gold alloys, and composite resins and epoxy resins and dental cement used in the present invention are used as materials.
[0036]
As shown in FIG. 2 and FIG. 3, in the example of the front tooth structure 2a and the posterior tooth structure 2b of the dental structure 2, the upper structures 2a-1 and 2b called "cores" of the upper gingival margin part. -1 and dowels 2 a-2 and 2 b-2 called “posts” that are installed and fixed in the root.
[0037]
Although the shape varies depending on the tooth type, it is roughly classified into two types for anterior teeth and molars.
[0038]
In the front tooth structure 2a, the upper structure 2a-1 has a slightly flat and blunt conical shape with a diameter of about 6 mm to 2 mm and a height of about 5 mm to 10 mm, and the nail 2a-2 has a taper. The pin has a diameter of about 4 mm to 1 mm and a length of about 5 mm to 10 mm.
[0039]
Also, in the molar structure 2b, the upper structure 2b-1 has a slightly elliptical turret shape with a major axis of about 4 mm to 8 mm and a height of about 5 mm to 8 mm, and the nail 2b-2 has the number of roots. Depending on the situation, a plurality of the shapes and sizes are the same as or slightly shorter than those for the front teeth.
[0040]
As shown in FIG. 4, the biological information measurement / recording / communication device 4 includes a sensor unit 6, a control / recording / communication unit 8 using an IC chip or the like, and an induction coil unit 10 also serving as a communication antenna. Is done.
[0041]
As shown in FIG. 1, when the above-described biological information measurement / recording and communication device 4 is molded by being encapsulated in, for example, the front tooth structure 2a, the sensor unit 6 includes the nature and number of sensors used and the measurement purpose. Accordingly, it is installed at various locations in the front tooth structure 2a. Since the control / recording / communication unit 8 is covered with a metal such as the dental crown prosthesis 14 and is electrically shielded, the control / recording / communication unit 8 is installed in the upper structure 2 a-1 called “core”. The induction coil unit 10 is installed in a portion of the nail 2a-2 called “post” for electromagnetic induction and communication with the outside.
[0042]
The molding method is performed in accordance with a crown restoration operation in normal dental treatment. That is, after obtaining an impression in the root canal of the tooth to be set with the dental structure 2, and making a working model with dental plaster, a dental structure 2 that conforms to this is manufactured with a wax mold. The process to do is not different from the manufacturing method of the general dental structure 2.
[0043]
Next, after burying the wax mold in a denture resin molding flask, the wax mold is poured away with hot water to form a mold. After the biological information measuring / recording and communication device 4 is further coated with silicon, and placed on the mold according to the above, an epoxy resin that is cured at room temperature is poured into the mold and cured.
[0044]
Then, for example, the front tooth structure 2a formed by encapsulating the biological information measuring / recording and communication device 4 inside is bonded to the tooth root 12 using dental cement as shown in FIG.
[0045]
In this state, an impression is taken, and after preparing a crown restoration 14 as shown in FIG. 6 according to a common method, it is bonded so as to completely cover the upper structure 2a-1 of the front tooth structure 2a. .
[0046]
This method is a method of custom-made the dental structure 2 for each tooth. However, in the dental treatment, a ready-made casting 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 body in which the biological information measuring / recording and communication device 4 is embedded. The usage method is that after forming the root canal in accordance with the shape of the dental structure 2, the dental structure 2 is set using dental cement, and an impression is taken to produce a crown prosthesis, It is to be attached to the dental structure 2 and is not different from a normal crown restoration treatment.
[0047]
After mounting, power is supplied to the biological information measuring / recording and communication device 4 by electromagnetic induction, and the control / recording and communication unit 8 using an IC chip or the like operates by this power supply to record biological data. .
[0048]
Note that the control / recording using the IC chip or the like and the recorded content of the communication unit 8 are protected by the security function, but when reading this out to the outside, the radio waves transmitted to the surroundings are intercepted and the encryption or the like can be decrypted The possibility of being used cannot be completely denied. For this reason, it is desirable to use a communication device that can ensure sharp directivity, such as microwaves, so that leakage radio waves are minimized when performing communication.
[0049]
Next, the operation principle of the biological information measuring / recording and communication device 4 will be described using a simple example.
[0050]
As shown in FIG. 7, a resistor 16 and a capacitor 18 are connected in parallel, and an induction coil 20 is connected in series to the resistor 16 and the capacitor 18 to form a closed circuit.
[0051]
Then, according to the resistance value of the resistor 16, the capacitance of the capacitor 18, and the inductance of the induction coil 20, a current is generated in the circuit by resonance with respect to a radio wave having a specific frequency.
[0052]
When an electric current is generated, a magnetic field fluctuation is generated in the surroundings. The magnetic field fluctuation is detected using, for example, a dip meter 22 such as an electric field and a resonance frequency measuring instrument, and the resonance frequency of the circuit is measured without contact. .
[0053]
When a thermistor is used as the resistor 16 of the circuit, a thermometer that measures the circuit in a non-contact manner can be obtained by detecting a change in the resonance frequency of the circuit in accordance with a change in the resistance value due to a temperature change.
[0054]
Further, an acceleration sensor can be applied as the resistor 16 to be used as a sphygmomanometer and an occlusal force meter by applying a strain gauge, and a hygrometer can be obtained if the capacitor 18 is a polymer capacitance change type humidity sensor. . In the near future, it will be possible to accommodate all sensors in an IC chip to realize multifunctional biological measurement.
[0055]
In addition to physiological information such as body temperature, pulse, blood pressure, and oxygen saturation, the basis of the biological information measurement / recording and communication device is blood image, blood glucose, cholesterol, neutral lipid, amino acid, tissue enzyme, ATP, antibody Power supply that also functions as an electronic sensor that measures biochemistry such as valence, immunological information, an IC chip having a measurement control logic circuit and a readable / writable storage device, and a non-contact communication It consists of an electromagnetic induction coil for supply.
[0056]
Basically, it is characterized by isolating the electronic device from the living body. Therefore, in living body sensing, acceleration, pressure, temperature, humidity, light or laser, magnetism, sound wave sensor, etc. that can be measured in a non-contact and non-invasive manner are mainly used. However, in cases such as endocrine diseases such as diabetes, immunity such as leukemia, AIDS, blood diseases, liver diseases, etc., it is possible to improve blood glucose levels, various enzymes, amino acids, electrolytes, antibody titers, etc. due to medical benefits. It can also be used for biosensing methods in which bioceramic sensors that directly detect chemical and immunological information are brought into contact with body tissue.
[0057]
For example, the body temperature is directly measured by installing an element such as a thermistor in a dental structure. Currently, a chip-type NTC (Negative Temperature Coefficient) thermistor (NTCCM1005: TDK Corporation) applied to refrigerators and air conditioners is supplied as a component having a size of about 1 mm. By using the simple element excluding these packages, it is possible to downsize the sensor as a micron unit, and it can be accommodated in a dental structure or implant body with a margin.
[0058]
Regarding the pulse, the pulse rate is calculated after detecting the vibration and pressure that the tooth receives due to the pulsation using the acceleration and pressure sensors. In blood pressure measurement, a phenomenon is used in which the pulse amplitude varies between the supine position and the standing position depending on the value.
[0059]
That is, the posture is detected using a fall switch, a hall element, and the like, and the pulse amplitude in both postures is measured by the acceleration sensor, and then the blood pressure value is calculated by difference calculation.
[0060]
In addition, for blood pressure measurement, a technique for measuring tooth strain due to pulse pressure using a strain sensor such as a strain gauge can be used.
[0061]
In this case, a microchip-sized pressure sensor (FPM-30PG: Fujikura Co., Ltd.) in which a piezoelectric silicon single crystal semiconductor element is coated with silicon gel, and an acceleration sensor (PKGS-00LA: Murata Manufacturing Co., Ltd.) in which piezoelectric ceramics are made into a bimorph. Co.)) can be downsized to a size of 1 cubic mm or less.
[0062]
Furthermore, a strain gauge, a thermocouple, or the like can be housed in the dental structure as a biosensor, and a part of these series of microsensors has already been applied to a blood vessel endoscope.
[0063]
In the future, in order to measure the blood oxygen saturation, the LED (Light Emitting Diode) assembled with an integrated circuit on a silicon wafer and a photodiode will be used to irradiate light from the inside of the tooth. Using a photoelectric sensor (photocoupler, photointerrupter) that detects the blood flow in the surrounding tissue as a photoelectric pulse wave, the composition ratio of oxyhemoglobin and deoxyhemoglobin is calculated by using multiple photoelectric sensors with different light wavelengths. Realize pulse oximetry.
[0064]
The humidity sensor detects moisture intrusion inside the device, which is a concern when embedding electronic devices in the living body, and is used as a measure to prevent device malfunctions and breakdowns. It would be possible to use the micro-resistive and high-capacitance variable humidity sensor (CHS-UGS, CHS-MSS: TDK Co., Ltd.), which is easy to miniaturize as a model. .
[0065]
The IC chip for controlling measurement and recording is desirably manufactured as a monolithic ASIC (Application Specific Integrated Circuit), but a plurality of general-purpose operation amplifiers, memories, control and communication chips may be combined.
[0066]
Considering the shape and size of the dental structure, the die size for a one-chip type IC chip is about 5 mm square if it is mounted for each tooth. The die size for mounting on a bridge denture or the like is not limited to this, and a size of about 5 mm × 30 mm square is applicable. In order to reduce the size of the IC, 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 sensor control program, and has a function of detecting and recording biological information by giving a command from the outside, and then transmitting the information to the outside via an antenna.
[0067]
Further, since the IC chip can be supplied with electric power from the outside by electromagnetic induction, there is no problem in operation even if it is completely embedded with a waterproof and moisture-proof material. Therefore, it can be stably placed even in a tissue filled with moisture, and can be used semipermanently. And since it has a function of reading and writing information, in addition to storing patient biometric information, it can store personal information associated with it, and by rewriting programs, encryption codes, etc. It is also possible to add a security function that blocks unintended access of the patient to the IC chip. In order to make privacy protection more complete, it is possible to provide a function of erasing or re-recording information stored in the IC chip according to a patient's request.
[0068]
In order to supply power to the electronic device used in the present invention and establish communication, the antenna in the root of the tooth needs to be able to receive radio waves that have passed through the soft tissue around the oral cavity and the alveolar bone.
[0069]
The antenna is required to efficiently transmit and receive with a diameter of about 1 mm to 2 mm and a length of about 5 mm to 10 mm. In order to ensure sufficient sensitivity and function as an induction coil, the communication antenna also functions as an induction coil. Therefore, in addition to a winding type coil with an air core or ferrite or alumina core as the core to ensure magnetic permeability, a laminated or thin film A type of coil inductor can also be used. In particular, small signal coils and chip inductors among these have been drastically reduced in portable terminals and the like, and those having a size of 1 cubic mm or less have already appeared.
[0070]
The shape of the antenna installed in the root space is desirably a cylindrical shape having a diameter of 1 mm to 3 mm and a length of 5 mm to 8 mm, and it seems easy to realize this size in the current state of the art.
[0071]
For example, although the coil on the rotating head in a video recorder is much smaller than the above size, it is also capable of high-speed friction (5 m / s to 6 m / s) with a video tape in an environment of several thousand revolutions per minute. It has durability that can be accommodated.
[0072]
When microwaves or the like are used for communication, a material with high impedance such as ceramic can be used as the antenna. Bioceramics such as hydroxyapatite, aluminas, and titanium oxide with high biocompatibility can also be used as an antenna, and in that case, the artificial dental root (fixture) in the implant itself can be used as the antenna.
[0073]
The biological information measurement / recording / communication device constructed in the present invention is basically composed of three parts: a sensor unit, a control / recording / communication unit, and an induction coil unit also serving as a communication antenna. . As is apparent from the inside of a terminal device such as a mobile phone, the input keyboard, the display device, and the built-in battery actually occupy most of the volume. On the other hand, the central part of the terminal is a CPU (central processing unit). Integrated in less than 10 chips, such as a processing device and a memory, and is surprisingly miniaturized. If the present invention is manufactured by an ASIC, a monolithic integrated circuit in which a sensor unit and a communication unit are integrated can be obtained.
[0074]
The present invention does not use any input key, monitor, battery, or any other parts that are bulky or heavy, and uses only electronic devices that can be easily miniaturized with the technology currently in practical use. Therefore, the present invention can be implemented immediately, and the benefits and cost performance for the present invention to penetrate the medical market are sufficiently secured.
[0075]
However, the needs from the medical field in the present invention will require further improvements in functionality and performance. Above all, the increase in the amount of information to be stored is the first decision. For example, a communication-type non-contact IC tag (VS-1: Shinwa Engineering Co., Ltd.) already sold has a 2 Kbyte memory mounted on a small sphere having a diameter of 5 mm. Although this amount of information is comparable to a document of about one page on A4 paper, there is a sense that it is somewhat unsatisfactory for recording biometric information in the present invention.
[0076]
At present, the storage capacity of a memory used as a storage element of a personal computer has been remarkably increased, and products exceeding 1 Mbit have already appeared on the market. In the recording of biological information in the present invention, by always adopting a new memory of that era, it will be possible to answer the need for more programmatic and complex functions that will be required in the future.
[0077]
Today, downsizing of batteries is progressing dramatically, and miniaturization will be achieved in the near future.
[0078]
In the present invention, since the battery is housed inside the dental structure that is an insulator and sufficient consideration is given so that current does not leak into the living tissue, in that case, a self-supporting operation by a built-in power supply is possible. Although these batteries must be rechargeable secondary batteries because they cannot be replaced for a long time once they are attached to a living body, the device can always operate independently of an external power source by securing a power source, The convenience is greatly improved.
[0079]
For example, when a patient's condition suddenly changes, an alarm can be sent, and it can be used for a technique for finding an elderly person who is hesitant. In the event of a distress, it may serve the decisive function of the light and darkness of the rescue. Although normal charging is performed by an external power source, by providing a power generation device such as a piezoelectric element or an inductor in the oral cavity, independent operation by power supply using pressure or acceleration by occlusion or masticatory force is also possible.
[0080]
In order to stably install the biological information measuring / recording and communication apparatus shown above in the patient's oral cavity, it is necessary to use a material that satisfies the following conditions when molding them into the shape of a dental structure . That is,
1. Does not affect the encapsulated electronic device,
2. It has sufficient strength as a dental structure,
3. Has waterproof and moistureproof ability,
4). Does not harm the living body,
5. Transmit radio waves,
6). Having an electrical insulator,
Etc. Dental filling materials such as composite resins that are already widely used in dental clinics generally meet the above-mentioned conditions, and these can be used to enclose a device and adjust the shape as a structure. Among these, epoxy resins (transparent epoxy GM-9002: Brennie Giken Co., Ltd.) have excellent electrical insulation and strength and can be molded at room temperature. It seems to be most suitable as a matrix.
[0081]
However, when these are used as materials for dental structures, cracks may occur during long-term use of materials with poor flexibility because they are subjected to repeated stress due to occlusal force. At that time, from the viewpoint of preventing the failure of the electronic device caused by the minute leakage of moisture, the epoxy device having strength after thinly covering the electronic device with a flexible material such as silicon when molding the device By adopting a so-called laminate structure that is encapsulated and molded with a material such as resin or composite resin, it is also necessary to consider the need to ensure a higher level of moisture and water resistance that can withstand long-term use.
[0082]
Installation of this device does not target vital teeth with pulp nerves that are extremely sensitive to electric current, but inactivated teeth that have lost their pulp due to dental inevitability, such as the etiology of dental caries and periodontal disease, and dental prosthesis Is targeted.
[0083]
The teeth collapse once due to caries, etc., and endodontic treatment is performed when the dental pulp is affected, but the teeth themselves become inactivated, but they can be preserved through the cementum on the root surface and can be maintained permanently. Is possible.
[0084]
The space in the root canal and pulpal cavity hollowed out by the endodontic treatment is later replaced with a dental structure to repair the crown. This dental structure has a volume sufficient to place an IC chip and an antenna having a die size of several millimeters square.
[0085]
Tooth that has undergone endodontic treatment is treated to completely block the invasion of tissue fluid and saliva around the tooth to prevent secondary caries that may occur after the treatment. There is little possibility of moisture intruding into certain parts, and there is almost no possibility of deterioration of the equipment due to corrosion of the sensor and IC chip by using a waterproof material as the material of the dental structure is there. Should the device stop functioning, it can be easily removed and replaced by replacing the artificial teeth.
[0086]
The teeth on which the biological information measuring device is present can be chewed in the oral cavity by covering the crown with a ceramic and metal crown based on a conventional restoration procedure, and does not cause an accident such as fracture.
[0087]
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 examinations such as X-rays and MRI (nuclear magnetic resonance).
[0088]
The head and neck with the oral cavity is an object that is always carefully protected against impact and invasion compared to the limbs and trunks, and is a stable environment both thermally and chemically. Therefore, it can be said that it is the most suitable place in the human body for placement of the electronic device if it is sufficiently protected from external force due to saliva or bite.
[0089]
Currently, in the oral cavity, a method of imprinting a patient name on a denture using a microchip has been proposed. Although this will not be unusable for biometric measurements, dentures will need to be self-managed by the patient, just like other portable devices, because dentures are intended to be attached and detached.
[0090]
There are many cases where many victims lose their dentures after a major earthquake.
[0091]
In the present invention, the use of the inactivated tooth is epoch-making in that complete integration between the electronic measuring device and the human body is realized, and biological information measurement and recording are completely automated. By using an IC chip for recording, safe management of information is promised. Above all, sensors, IC chips, and other electronic devices that are originally foreign substances to the living body are completely encapsulated in a dental structure and attached to inactivated teeth, and further, due to the strictness of covering with a metal or ceramic crown, Sufficient safety is ensured against foreign body reactions that cannot be avoided when implanted in living tissue and leakage of metals and chemicals that are not welcomed by living bodies.
[0092]
The biological information measuring / recording and communication device installation site in the present invention is a useless space created after treatment of inactivated teeth. Therefore, there is no new invasion or pain to the living body due to the installation of the device. Moreover, it is safe and secure, has high convenience for maintaining health, and does not cause any moral and ethical problems like other implantable medical devices. A medical device such as a cardiac pacemaker is essentially different from a medical device implanted in a living body due to unavoidable circumstances.
[0093]
The present invention is implemented in conjunction with daily dental treatment, and even a healthy person can be used without resistance.
[0094]
In this sense, the present invention contributes to the practice of amenity medicine in a new era and can be expected to be widely used as a health care tool for future medicine that supports patient health and social activities.
[0095]
FIG. 8 shows a second embodiment of the present invention. In the second embodiment, portions that perform the same functions as those of the first embodiment will be described with the same reference numerals.
[0096]
The feature of the second embodiment is that the information terminal means 32 is connected to the biological information measuring / recording and communication device 4 enclosed in the dental structure 2, for example, the front tooth structure 2a. The information terminal means 32 controls biological information measurement / recording and information input / output of the communication device 4.
[0097]
That is, as shown in FIG. 8, the biological 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 an induction coil unit 10 serving also as a communication antenna. It is comprised by.
[0098]
The information terminal means 32 has a bidirectional communication function. For example, a portable information terminal (also referred to as “portable communicator” or “PDA terminal”) 34 or a fixed information terminal (“ 36) (also referred to as “fixed type communicator”).
[0099]
More specifically, as shown in FIG. 8, the portable information terminal 34 includes a main body part 34-1 formed to have a passport size so as to be portable, and a display screen part provided in the main body part 34-1 34-2 and a plurality of button operation units 34-3 for controlling information input / output.
[0100]
The fixed information terminal device 36 includes a main body 36-1 including a personal computer, a display unit 36-2, a keyboard unit 36-3 and a mouse unit 36-4 for input / output operations. .
[0101]
In addition, the information terminal means 32 periodically reads and writes the biological information measurement / recording and communication device 4 to constantly monitor the biological information such as the body temperature, blood pressure, and pulse pattern of the person. .
[0102]
A specific example will be described below.
[0103]
The biological information measurement / recording and communication device 4 enclosed in the dental structure 2, for example, the front tooth structure 2a, functions as a biosensor and communicates with the biological information measurement / recording and communication device 4. Thus, the information terminal means 32 including the portable information terminal 34 and the fixed information terminal device 36 acquires the biological information from the biological information measuring / recording and communication device 4.
[0104]
The portable information terminal 34 can acquire and record biological information at all times by being carried by a wearer of the biological information measuring / recording and communication device 4 which is a biological sensor.
[0105]
On the other hand, the fixed type information terminal device 36 is used when the wearer does not use the portable information terminal 34 for some reason, for example, at the time of going to bed or taking a bath, or when going to hospital or hospitalization, and the appropriate organization. It is used when, for example, performing acquisition and description (update) of appropriate information for the fixed information terminal device 36 under medical management (medical institution, fire fighting, police, legal affairs, etc.).
[0106]
As the measurement function provided in the biological information measurement / recording and communication device 4, it is possible to incorporate sensors for acceleration, temperature, light, pressure, posture (positioning), magnetism, and the like that are currently miniaturized. .
[0107]
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. Can be used for management.
[0108]
Further, the present invention is installed in a dental structure 2 in the oral cavity, for example, the front tooth structure 2a, and a head that may occur in the event of an accident or crime unfortunately encountered by using an acceleration sensor. It can be applied to an alarm system for transmitting an injury to a human body as an alarm by detecting an abnormal impact on a part.
[0109]
With regard to these crisis management applications, the sensor described above is often taken into account in cases where the limbs and body of the human body often dare to accept considerable impacts even in situations that are not abnormal, such as during sports. Is a function unique to being installed on the head, and has the potential to realize an exclusive physical management function compared to other biosensor usage methods installed on parts other than the head .
[0110]
In addition, the head in the human body is a particularly protected subject, where the loss of blood pressure and pulse and vibrations and shocks that greatly exceed daily averages are directly linked to disorders of the central nervous system, the seat of life. Is.
[0111]
Therefore, the biological information measurement system in the oral cavity can provide a security function that can be most related to life safety.
[0112]
For example, the health management of elderly people living alone is a major issue in developed countries where an aging society is accelerating.
[0113]
Although it is impossible to force the elderly to carry out physical management such as carrying an electrocardiogram, thermometer, respiratory sensor, blood pressure monitor, etc., such as a centralized control room (ICU) of a hospital, and constantly monitoring, The living body information measurement / recording and communication device 4 and the portable information terminal 34 enclosed in the built-up body 2, for example, the front-tooth built-up structure 2a, can be worn, and the stress of the wearer is stressed for most of the body management functions. It is possible to provide without accompanying.
[0114]
In other words, 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 light source in the red and near infrared bands is secured by a light emitting diode, etc. Measurement of oxygen saturation can be realized.
[0115]
The information terminal means 32, particularly the portable information terminal 34, can detect a sudden change in physical condition and issue an alarm by constantly monitoring the attached sensor and monitoring biological information.
[0116]
However, in these implementations, for example, in the case of sudden changes in physical condition, the time when fluctuations in pulse rate and blood pressure were detected, and the case where fluctuations in blood pressure occurred due to exercise or heavy work in normal life Need to be identified.
[0117]
For this reason, when an abnormal value is detected in these pulse and blood pressure sensors, the state of the posture sensor is simultaneously monitored.
[0118]
That is, in most cases during sudden changes in physical condition, the posture of the sensor wearer is in a continuous supine or prone posture, while the posture of the wearer is upright due to increased blood pressure or pulse caused by exercise or work load It is. Therefore, when the increase in pulse / blood pressure of the sensor wearer is detected, the information terminal means 32, particularly the portable information terminal 34, can be detected by simultaneously detecting whether or not the posture is in the supine position. It is possible to determine the emergency situation of the sensor wearer with high accuracy and automatically issue an alarm.
[0119]
However, when the device of the present invention is always applied in daily life as described above, the biological information measurement / recording and communication device 4 to be worn in the oral cavity and the information terminal means 32 for managing / operating it. In particular, the portable information terminal 34 must always be linked.
[0120]
If the biometric information recording in the present invention is performed as needed, it is not necessary to carry the portable information terminal 34, but medical cases such as those having a disease that seriously impedes the maintenance of the body. If what is always under control is desirable, it is necessary to always carry the portable information terminal 34. For this purpose, the portable information terminal 34 constantly monitors the operation of the biometric information acquisition function so as to always cooperate with the biometric information recording device.
[0121]
For example, there is a case where the portable information terminal 34 is sometimes removed from the wearer when changing clothes or taking a bath, and the acquisition of biological information is interrupted. When the biometric information acquisition by the device 34 is not resumed, it is desirable that the portable information terminal 34 has a security function for issuing an alarm.
[0122]
These systems can be used as useful security tools for issuing warnings of emergency situations to healthy people. For example, the problem of bullying by schoolchildren and students is a major social problem that has long been desired to be resolved, but the major factor that has prevented its resolution so far is the victim's bullying fact. It is nothing but an example of hesitation in the announcement.
[0123]
Victims are hesitant to announce firstly in an environment where bullying is concealed, that is, in places where there is little possibility of witnessing by third parties, and second, to prove the damage suffered by the victims The third reason is that the victim's voluntary accusation is blocked by the perpetrator.
[0124]
The biological information measurement / recording and communication device 4, which is a biological information measurement system installed in the oral cavity, detects in real time the harmful effects caused by violence, such as the impact caused by injury to the victim and the update of pulse / blood pressure. At the same time, an alarm is issued and the situation is recorded.
[0125]
As a result, the notification of the bullying damage is surely reported to the appropriate organization without being obstructed by the perpetrator's intention, and the incident can be investigated quickly and reliably.
[0126]
These systems will be a great deterrent to the violence of school children and students, and if they are used in general, they can be used as a means to realize a safer social environment.
[0127]
9 to 12 show a third embodiment of the present invention.
[0128]
The feature of the third embodiment is that a biological information measuring / recording and communication device 42 applied to a security tool based on biological dynamism pattern authentication is disclosed.
[0129]
That is, the biological information measuring / recording and communication device 42 is a biological sensor installed as the dental structure 2 and can always record the biological information of the wearer using the biological sensor.
[0130]
Such information includes pulse, blood pressure, body temperature, blood oxygen saturation, and the like.
[0131]
As an example, according to the knowledge of the third embodiment based on the operating principle, a pulse wave can be acquired using an optical sensor installed in the oral cavity.
[0132]
Here, a method for obtaining a pulse wave based on a light detection method from the dental pulp is disclosed.
[0133]
For example, as shown in FIG. 9, a photodiode 46 that performs light detection and a light emitting diode (also referred to as “LED”) 48 that serves as a light source are attached to the maxillary anterior teeth 44 by a holder 50.
[0134]
At this time, after irradiating monochromatic light of 568, 660, and 940 nm on the lingual side of the maxillary anterior teeth 44 from the light emitting diode 48 mounted on the lingual side of the maxillary anterior teeth 44, the light transmitted through the maxillary anterior teeth 44 is transmitted by the photodiode 46. Detect.
[0135]
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 front teeth 44 by a holder 50.
[0136]
Then, after irradiating visible light, near-infrared light, and near-ultraviolet light with an arbitrary wavelength from the lingual side of the maxillary anterior teeth 44 through the optical fiber 52, the light transmitted through the maxillary anterior teeth 44 is detected by the photodiode 46.
[0137]
At this time, the characteristics of the irradiation light and the photodiode 46 need to be adjusted as needed depending on the type of biological information to be searched, but the light source has an effective value of 100 μm (micron) which is an intensity that does not cause harmful effects on the living body. ) About W.
[0138]
The graph waveform disclosed in FIG. 11 is obtained by detecting the transmitted light after irradiating the maxillary anterior teeth 44 with green light of 568 nm using the light emitting diode 48 as a light source.
[0139]
In the left and right waveforms of FIG. 11, the upper stage (supplied with “TLP”) is the light intensity transmitted through the maxillary anterior teeth 44, and the lower stage is the electrocardiogram (supplied with “ECG”) of the measurement subject.
[0140]
The output by the light transmitted through the maxillary anterior teeth 44 changes in parallel with the pulse of the subject. This reflects fluctuations in the pulpal blood flow of the maxillary anterior teeth 44 due to the pulse, and is referred to as transmitted light photoplethysmography (Transmitted Light Photoplethysmography).
[0141]
In such a case, light in the visible short wavelength region having high absorption characteristics for blood hemoglobin is used so that the blood flow rate can be easily reflected.
[0142]
In order to extract transmitted light limited to only teeth, it is effective to opaque or mask other than the teeth to be measured to prevent light from being mixed from other than the objects to be measured.
[0143]
The graph waveform on the right side in FIG. 11 is the result of measurement using a black rubber dam sheet that masks other than the teeth to be measured, and shows that the amplitude of the waveform obtained is greatly reduced compared to the left side. ing.
[0144]
This indicates that even if light is introduced from the teeth toward the surrounding tissue, the pulse wave can be detected from the light propagated to the surrounding tissue.
[0145]
FIG. 12 is a transmitted light photoelectric pulse wave for teeth having light sources of 660, 810, and 940 nm. Although a pulse wave is obtained when a light source of 810 or 940 nm is used, a light source of 660 nm is used. This indicates that the pulse wave cannot be extracted, and it can be understood that it is necessary to select an appropriate light source depending on the search target.
[0146]
Already, micro-photo coupling has been put into practical use that creates a system that detects light emission and converts it into electrical output in an integrated circuit such as a semiconductor relay.
[0147]
It is easy to apply these in the IC chip of the biological information measuring / recording and communication device 42 of the third embodiment, and adding a photoelectric pulse wave measuring function to the biological information measuring / recording and communication device 42. Is also possible.
[0148]
In addition to the above, for pulse measurement, a method for detecting local vibration caused by pulsation with an acceleration sensor and a method for detecting local tissue pressure due to blood pressure have been established.
[0149]
That is, in the living body information measuring system in the third embodiment, that is, the living body information measuring / recording and communication device 42, the vital signs of the living body are not only numerical data such as the pulsation rate and blood pressure but also the pulse wave. It is possible to obtain a two-dimensional image.
[0150]
The function to acquire a fine waveform image of a human vital sign is used for medical management for maintaining physical health such as diagnosis of cardiovascular function using an electrocardiogram waveform, and a security system that transmits the physical crisis of the person. In addition, it can be used as a highly accurate identity verification means.
[0151]
Such a system, of course, stores the wearer's identity and medical personal information in case of an emergency such as the wearer's lack of personnel, and as such ensures the function of identification. Cases are likely to occur.
[0152]
This is because the biometric information measurement / recording and communication device 42 is embedded in the teeth, unlike a credit card or a license, so that the risk of theft or loss is extremely low, and it is highly reliable as a means of identification. It is because it has sex.
[0153]
However, in the unlikely event of unauthorized access to the IC chip of the biological information measuring / recording and communication device 42, such as copying and forging of card data due to skimming, which has been rapidly increasing as a credit card crime in recent years, Your personal information may not be copied and your identification function may not be counterfeited.
[0154]
Therefore, when using the biometric information measurement / recording and communication device 42 with an authentication function, pay attention to the fact that the shape of the pulse wave at the time of human rest is almost constant, and record this in advance. After creating a pattern for each individual, it is registered as a data pace.
[0155]
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 biometric information measurement / recording and IC card recording information of the communication device 42.
[0156]
In this way, a biological dynamism pattern authentication function can be provided.
[0157]
The first feature of this vital pattern authentication lies in the authorizing from the viewpoint of “social life”.
[0158]
In other words, it is possible not only to completely prevent impersonation of others due to card duplication / counterfeiting as seen in credit card crimes, but also when the wearer suffers a significant modulation in the body, for example by the death of the wearer When the biological information measuring / recording and communication device 42 can no longer detect vital signs, the function as the authentication body can be lost at that time.
[0159]
This is particularly effective in fields that require a high level of security. For example, it can be used to deter aircraft hijacking crimes.
[0160]
First, the biological information measurement / recording / communication device 42 is mounted and operated in the oral cavity of the pilot, and on the aircraft side, the biological information measurement / recording / communication device 42 is authenticated, and the pilot can freely operate. Functions that become possible are added in advance.
[0161]
It should be noted that even when the aircraft is in flight, a system in which free maneuvering cannot be performed unless the biological information measurement / recording and communication device 42 functions as an authentication body in the vicinity of the cockpit.
[0162]
If the pilots are removed from the cockpit by the hijacker, or if the pilot dies in the worst case, the aircraft cannot authenticate the biometric measurement / recording and communication device 42 and the aircraft is forced to Auto pilot.
[0163]
In the case of autopilot, keep turning until the minimum amount of fuel required for landing near the nearest airport, or landing by remote control of aircraft developed recently or automatic landing by aircraft confidence, etc. By programming to implement, the hijacker can be prevented from flying the aircraft to its destination.
[0164]
Such an advanced security function is unique to an authentication body such as a biometric information recording / recording and communication device 42 that recognizes a vital sign of a living body, and can be said to be an ultimate personal authentication system. is there.
[0165]
The present invention is not limited to the first to third embodiments described above, and various application modifications can be made.
[0166]
For example, the biometric information measurement / recording and communication device disclosed in the first to third embodiments of the present invention records various personal information necessary for medical management in addition to the wearer's biometric information. Although it has a function, it is very useful to respond to emergency situations such as sudden changes in physical condition, while this information is always present with the wearer, while personal information regarding the wearer's privacy is There is a possibility of theft. In some cases, tampering with the wearer's confidence may occur.
[0167]
Therefore, it is also possible to adopt a configuration in which security measures such as encryption are performed when personal information is recorded on the biological information measurement / recording and communication device.
[0168]
In other words, data to be protected by encryption includes the wearer's name, address, date of birth, contact information, insurance card number and symbol, blood type, as well as the wearer's data entered by medical institutions as necessary. Contents related to medical care (medical history, progress, prescription, items to be communicated to patients, etc.) are included.
[0169]
As an encryption method, the use of common key encryption used as a general encryption method is considered, but there is room for data alteration by the wearer in the common key encryption method.
[0170]
Therefore, when a medical institution introduces a wearer to another hospital, when medical information is recorded on biological information measurement / recording and communication devices, public key cryptography is used as a more secure encryption method. It is desirable to use it.
[0171]
In this case, the medical institution that performs the inquiry encrypts the inquiry item with the public key of the referral destination, and decrypts the data with the private key of the referral destination medical institution.
[0172]
In this case, sufficient security measures can be taken by encryption when measuring / recording biometric information and recording personal information in the communication device.
[0173]
Moreover, it is also possible to adopt a measure in which the biological information measuring / recording and communication device disclosed in the first to third embodiments of the present invention is installed in the correction bracket and installed in the oral cavity.
[0174]
That is, the biological information measurement / recording and communication device is exposed in the oral cavity.
[0175]
Then, since the biological information measurement / recording and communication device can be exposed in the oral cavity, a pH sensor can be incorporated as a sensor, and the acidity of the oral saliva by the pH sensor. By measuring the caries prevention system and measuring the electrical resistance of the ingested food, it is possible to realize a salt intake monitor, which can help the wearer's health management, and is practically advantageous. is there.
[0176]
Further, in the biological information measurement / recording and communication device exposed in the oral cavity, an aerial (antenna) that communicates with the outside is secured in a loop coil shape that covers the outer periphery of the biological information measurement / recording and communication device. Alternatively, the stainless steel wire used for the correction bracket can be used together as an aerial, which facilitates production.
[0177]

Detailed biological data can be used to improve diagnostic accuracy and to achieve detailed medical maintenance. Since the device is completely covered with a prosthesis such as a metal crown, it is very unlikely that others will know the ownership of the device. By using an IC card for the recording device, confidentiality is ensured, and even medical information related to private and human rights such as AIDS and hepatitis can be safely held.
