  SUMMARY OF THE INVENTION An object of the present invention is to provide a health condition diagnosis system capable of making a wider diagnosis by measuring three-dimensional movement information of a specific part of the body, and having a simple configuration and low cost.

A health condition diagnosis system including a three-dimensional accelerometer according to the present invention includes a three-dimensional acceleration sensor chip attached to a specific part of a body, and a three-dimensional component obtained by integrating detection values of the three-dimensional acceleration sensor for each three-dimensional component. A means for calculating changes in speed and position, a storage unit storing comparison data corresponding to a specific part of the body, and a result of comparing the calculated three-dimensional speed or position change information with the comparison data. It consisted of means to do.
The three-dimensional centroid system of the present invention includes a three-dimensional acceleration sensor chip attached to a plurality of specific parts of the body including the top of the head, the cervical vertebra, the upper limb, and the lower limb, and a detection value of the three-dimensional acceleration sensor for each three-dimensional component. Means for calculating a change in the three-dimensional position of each part by integrating twice, means for analyzing the health state from the calculated change information of the three-dimensional position of each part, and displaying the analysis result It consisted of means. Further, in addition to the configuration, a storage unit that stores comparison data corresponding to a plurality of specific parts of the body, and means for displaying a result of comparing the calculated change information of the three-dimensional position of each part with the comparison data Present the one with.

A pathological diagnosis system for brain / neurological diseases or a support system for medication prescription or function recovery training provided with a three-dimensional accelerometer according to the present invention includes a three-dimensional acceleration sensor chip attached to a fingertip, and the three-dimensional acceleration sensor Means for calculating a three-dimensional velocity and position change by integrating the detected value for each three-dimensional component, a test pattern drawn with a fingertip, and a storage unit storing comparison data describing the test pattern It comprises means for displaying the result of comparing the three-dimensional velocity or position change information with the comparison data.
And the comparison data employ | adopted above were made into the healthy subject data, the sick or disabled data of each level, the past self data, or these combination.

  In the health condition diagnosis system equipped with the three-dimensional accelerometer of the present invention, the three-dimensional acceleration sensor chip attached to a specific part of the body is a small piece (dimension of about 10 × 10 × 2 mm), and has a three-dimensional velocity and position. Means for calculating change, storage unit storing comparison data corresponding to a specific part of the body, and means for displaying the result of comparing the calculated three-dimensional speed or position change information with the comparison data are ordinary Since it can be realized using a personal computer, if the output of the three-dimensional acceleration sensor can be input to a personal computer, it can be realized simply by connecting the chip and the personal computer. It is possible to realize change information measurement of the three-dimensional velocity or position of a specific part of the body with an extremely simple configuration and at low cost. Moreover, it is possible to deal with a wide range of health condition diagnosis by obtaining three-dimensional information.

In the three-dimensional centroid system of the present invention, the three-dimensional acceleration sensor chip attached to a plurality of specific parts of the body including the top of the head, the cervical vertebra, the upper limb, and the lower limb is a small piece (dimension of about 10 × 10 × 2 mm). A means for calculating a change in the three-dimensional position of each part by integrating the detected value of the acceleration sensor twice for each three-dimensional component, and analyzing the health state from the calculated three-dimensional position change information of each part. Since the means for displaying and the means for displaying the analysis result can be realized by using a normal personal computer, this system is also basically capable of inputting the output of the three-dimensional acceleration sensor to a personal computer. This can be achieved simply by connecting the chip to a personal computer. Compared to a center of gravity meter (a regular triangle of about 600 mm, or a rectangle of about 10 kg) that measures by installing a load sensor on a conventional plate, the three-dimensional speed of a specific part of the body can be reduced with a very simple structure and at a low cost. Position change information measurement can be realized. The conventional center of gravity meter requires a certain range of area in a flat place where the plate is installed, but this system using an accelerometer does not choose the place. The measuring method is not limited to a conventional upright or sitting position, and can be carried out on a bed or walking. Thus, it is possible to cope with a wide range of health condition diagnosis by obtaining three-dimensional information in various forms. In addition, by summing up the shaking of each part, the center of gravity data output from the current center of gravity meter can calculate a value close to 1 as the correlation coefficient, which can be compared with conventional data.
Further, in addition to the configuration, a storage unit that stores comparison data corresponding to a plurality of specific parts of the body, and means for displaying a result of comparing the calculated change information of the three-dimensional position of each part with the comparison data If it is equipped with a health condition diagnosis becomes easy.

The same applies to the pathological diagnosis system for brain / neurological diseases provided with the three-dimensional accelerometer of the present invention, and the three-dimensional acceleration sensor chip attached to the fingertip is a small piece (dimension of about 10 × 10 × 2 mm). Means for calculating a change in three-dimensional velocity and position by integrating the detected value of the acceleration sensor for each three-dimensional component; a storage unit storing a test pattern drawn with a fingertip and comparison data describing the test pattern; The means to display the result of comparing the calculated three-dimensional velocity or position change information with the comparison data can be realized using a normal personal computer, so the output of the three-dimensional acceleration sensor can be input to the personal computer. Basically, it can be realized simply by connecting the chip and the personal computer.
The conventional device requires a certain range of area on a flat place such as a desk where the plate is installed. However, the system using the accelerometer of the present invention does not choose a place and can measure even when the subject is sleeping. Is possible. The conventional apparatus can obtain only two-dimensional information (X, Y) obtained by tracing a model figure, but the present invention using a three-dimensional accelerometer adds X, Y, Z and 3 with depth parameters. Since dimensional information can be obtained, a wider diagnosis is possible. That is, in order to trace a three-dimensional test pattern in space, space recognition and memory of the size and shape of the test pattern, and feedback capability using higher brain functions that realize memory and recognition are required. This makes it possible to evaluate and train complex cognitive functions that could not be achieved with. Further, since the test pattern on the paper surface can be traced, it can be used in the same manner as the conventional apparatus, and can be directly compared with past data from the conventional apparatus.
Even when the present invention is used as a medication prescription support system equipped with a three-dimensional accelerometer or a support system for functional recovery training, the above-mentioned brain / nervous system can be obtained only by changing the use form of the diagnosis result data. This is the same as the case of the disease state diagnosis system.

  Then, in the present invention, healthy data, each level of sick or disabled data, past self data, or a combination thereof is stored in the storage unit as comparison data, and is compared with the measurement data for diagnostic material. Therefore, appropriate diagnosis can be easily performed.

It is a system block diagram which shows the basic composition of this invention. It is a figure explaining the example of embodiment of the health-diagnosis system provided with the three-dimensional accelerometer of this invention. It is a figure explaining the example of the simplest embodiment of the health-diagnosis system provided with the three-dimensional accelerometer of the present invention.

  Hereinafter, embodiments of the present invention will be described in detail. As shown in the system block diagram of FIG. 1, the basic configuration of the present invention is a three-dimensional acceleration sensor 1 and an arithmetic processing unit 3, a storage unit 4 having a program and data storage function, an input means 5 such as a keyboard, and a display unit. 6 and a conversion unit 2 that converts the output of the three-dimensional acceleration sensor 1 into a signal form that can be input to the personal computer 10. Since the three-dimensional acceleration sensor 1 used in the present invention needs to be stably attached to a desired part of the body, a small flat chip-shaped chip is used. Incidentally, a component of about 10 × 10 × 3 mm is in circulation as this type of component, and can be implemented using this. The movement of the part to which the three-dimensional acceleration sensor chip 1 is attached is detected as acceleration information divided into three-dimensional components of x, y, z orthogonal coordinates. Obviously, if acceleration information is integrated once, velocity information is obtained, and if integrated twice, displacement information is obtained. Then, by combining the three-dimensional components of x, y, z orthogonal coordinates, it is possible to obtain vector information having a direction. The displacement amount indicates the relative position change of the part at every sampling time, and the movement of the part can be grasped by sequentially superimposing the displacement amount on the initial position. When the three-dimensional acceleration sensor chip 1 is attached to a plurality of parts, if the initial position of each part is known, not only the movement of the part but also the relative displacement between the parts, that is, the movement of the body is grasped. Can do.

  Explaining the basic operation of the present invention, the detection signal output from the three-dimensional acceleration sensor chip 1 is first converted into a signal form that can be handled by the computer 10 by the conversion unit 2. For example, when the detection signal output from the USB driver and the three-dimensional acceleration sensor chip 1 is an analog signal, the conversion unit 2 converts the signal into digital information. When the detection signal to be output is weak It has a built-in amplifier to amplify. This detection signal is integrated once by the calculation unit 3 by a program stored in the storage unit 4 to obtain velocity information of the part, and further integrated to obtain a displacement amount. The obtained information is accumulated in the data storage area of the storage unit 4. Subsequently, the comparison information specified by the program is read from the comparison information database stored in the data storage area of the storage unit 4 and displayed on the display unit 6 in comparison with the detected data. This display is preferably displayed in a graph form or a table form so that the health condition of the subject can be easily determined. If the comparison data is data indicating a border with a healthy person, it is easy to determine whether or not the subject is a healthy person. In addition, it is easy to determine the medical condition or degree of disability of the subject if it is sick or disabled data at each level, and the state transition of the subject can be determined if the subject's past self-data. In addition, the comparison data is not one, and if a plurality of the comparison data are provided, various determinations and diagnoses are possible. The input means 5 is responsible for input of selection of programs, selection of comparison data, subject ID information, and the like regarding what tests and data processing are to be performed.

  FIG. 2 illustrates three embodiments of the “health condition diagnosis system including a three-dimensional accelerometer” according to the present invention. In the figure, A shows a form I in which the detection signal output from the three-dimensional acceleration sensor chip 1 is directly connected to the computer 10 by wire to perform inspection and display of the result in real time. In this embodiment, the USB controller BOX 2b performs processing necessary to make the output signal of the three-dimensional acceleration sensor chip 1 be handled by the computer 10. Functional elements that the USB control controller BOX 2b must have are a three-channel amplifier, a USB driver, and an AD converter. The triaxial acceleration sensor 1 attached to a specific part of the body detects the acceleration separated into the three-axis direction components of the part and transmits it to the USB controller BOX 2b. In the USB controller BOX 2b that receives the signal, the signal is amplified for each component in the three axial directions, the analog signal is converted into a digital signal, and the signal is converted into a form that can be received by the USB terminal of the computer 10 to the computer 10. Output. Receiving the measurement signal, the computer 10 integrates once in the calculation unit 3 according to the program to obtain velocity information of the part, and further integrates to obtain the displacement amount. The obtained information is accumulated in the data storage area of the storage unit 4. Subsequently, the comparison information specified by the program is read from the comparison information database stored in the data storage area of the storage unit 4 and displayed on the display unit 6 in comparison with the detected data. This series of operations is executed in real time. The USB controller BOX 2b needs to be attached to the subject in a stable state, and a wristband type attached to the wrist or ankle or a form attached to a belt is adopted.

  In FIG. 2B, the detection signal output from the three-dimensional acceleration sensor chip 1 is directly connected to the USB control controller BOX 2b by wire and transmitted to the computer 10 wirelessly to perform inspection and display the result in real time II. Is shown. In this embodiment, the USB control controller BOX 2b and the USB receiver 2c perform processing necessary to make the output signal of the three-dimensional acceleration sensor chip 1 wirelessly transmitted to the computer 10. The functional elements that the USB control controller BOX 2b must have are a battery and a wireless (Bluetooth) transmitter in addition to a 3-channel amplifier and an AD converter. The recommended wireless type is Bluetooth, which uses a 2.4 GHz frequency band to exchange information between adjacent devices (equipment) and devices. A USB receiver 2 c is inserted into the USB terminal of the computer 10 so that the computer 10 can receive radio signals. The triaxial acceleration sensor 1 attached to a specific part of the body detects the acceleration separated into the three-axis direction components of the part and transmits it to the USB controller BOX 2b. In the USB controller BOX 2b that receives the signal, the signal is amplified for each of the three axial components, the analog signal is converted into a digital signal, modulated from a wireless (Bluetooth) transmitter to a wireless carrier, and transmitted wirelessly. The computer 10 receives a wireless signal by the USB receiver 2 c connected to the USB terminal, demodulates the data signal, and inputs the data signal to the computer 10. Receiving the measurement signal, the computer 10 integrates once in the calculation unit 3 according to the program to obtain velocity information of the part, and further integrates to obtain the displacement amount. The obtained information is accumulated in the data storage area of the storage unit 4. Subsequently, the comparison information specified by the program is read from the comparison information database stored in the data storage area of the storage unit 4 and displayed on the display unit 6 in comparison with the detected data. This series of operations is executed in real time. This configuration has the advantage that the computer 10 does not need to be connected to the USB control controller BOX 2b by wire, and the subject is not restricted by the USB code, and can be examined in a more natural manner. However, since the power required by the three-dimensional acceleration sensor chip 1 and the USB control controller BOX 2b cannot be supplied from the computer 10, it is necessary to provide a battery in the USB control controller BOX 2b.

In FIG. 2C, the detection signal output from the three-dimensional acceleration sensor chip 1 is transmitted directly to the USB control controller BOX 2b connected by wire, and after performing necessary data processing, the detection data is temporarily stored in the USB control controller BOX 2b. An off-line embodiment of a data logger method for storing and accumulating is shown. In this embodiment, the output signal of the three-dimensional acceleration sensor chip 1 is temporarily stored and stored in the USB controller BOX 2b, and processing necessary to make it possible to input the computer 10 is performed by the wristband type USB controller BOX 2b. The functional elements that the USB control controller BOX 2b must have are a battery and a CPU and memory for performing calculation functions and storing / reading data in the memory in addition to a 3-channel amplifier, an AD converter, and a USB driver. . The USB controller BOX 2b is carried to a place where the computer 10 is stored in a state where measurement signals are accumulated, and the output terminal and the USB terminal of the computer 10 are connected by a USB cord. The computer 10 that has received the data signal accumulates the received information in the data storage area of the storage unit 4 according to the program, and the comparison information specified by the program is stored in the data storage area of the storage unit 4. The data is read from the database and displayed on the display unit 6 in comparison with the detected data. This series of operations is executed in real time. In the above example, after the necessary data processing is performed in the USB controller BOX 2b, the detected data is temporarily stored and stored in the USB controller BOX 2b. However, the detected acceleration data is simply integrated without being integrated. It may be configured to store and accumulate as acceleration data and integrate in the computer 10 to obtain speed information and displacement information. Since this form does not require the presence of the computer 10 at the time of inspection, it is not necessary for the person performing the test to bring the computer 10 to the destination, and it is only necessary to perform data processing and result display on the computer in the room after returning home. Ideal for inspection. Also in this embodiment, since the power necessary for the three-dimensional acceleration sensor chip 1 and the USB control controller BOX 2b cannot be supplied from the computer 10, it is necessary to provide a battery in the USB control controller BOX 2b.
In the above description, the three embodiments shown in FIG. 2 have shown that one three-dimensional acceleration sensor chip 1 is connected to the USB control controller BOX 2b by wire. The USB controller BOX 2b provided with the input terminal is used. Therefore, even in this case, the USB control controller BOX 2b that the subject must wear is one.

  The form shown in FIG. 3 is the simplest embodiment of the present invention. The detection signal output from the three-dimensional acceleration sensor chip 1 is connected to the 3-channel amplifier 2a by wire, and the AD conversion board 2d connected to the output terminal of the 3-channel amplifier 2a and the USB terminal of the computer 10 is connected by wire. The form which performs a test | inspection and its result display is shown. In this embodiment, the output signal of the three-dimensional acceleration sensor chip 1 is amplified by the three-channel amplifier 2a, and processing necessary for making the computer 10 handle the signal is performed by the AD conversion board 2d. Functional elements that the AD conversion board 2d must have are a USB driver and an AD converter. The triaxial acceleration sensor 1 attached to a specific part of the body detects the acceleration separated into the three axial components of the part and transmits it to the three-channel amplifier 2a. Upon receiving the signal, the 3-channel amplifier 2a amplifies the signal for each component in the three axial directions and sends it to the AD conversion board 2d. The AD conversion board 2 d that has received the signal converts the analog signal into a digital signal, further converts the signal into a form that can be received by the USB terminal of the computer 10, and outputs the signal to the computer 10. Receiving the measurement signal, the computer 10 integrates once in the calculation unit 3 according to the program to obtain velocity information of the part, and further integrates to obtain the displacement amount. The obtained information is accumulated in the data storage area of the storage unit 4. Subsequently, the comparison information specified by the program is read from the comparison information database stored in the data storage area of the storage unit 4 and displayed on the display unit 6 in comparison with the detected data. This series of operations is executed in real time. Only the triaxial acceleration sensor 1 can be attached to the subject in a stable state. However, in this embodiment, when sensors are attached to a plurality of locations on the body, it is burdened on the subject to perform a test by connecting a plurality of signal lines to the 3-channel amplifier 2a. A form to be attached to is preferable. In that case, if a multiplexer is arranged at the input end of the three-channel amplifier 2a and the multi-channel switching of the signal line is performed, one three-channel amplifier 2a can be used in common.

  The Example which uses the health-conditions diagnosis system provided with the three-dimensional accelerometer of this invention as a centroid is shown. A conventional center of gravity meter has three to four strain gauges or load sensors installed on the plate at regular intervals, and the center of pressure (hereinafter abbreviated as COP) as a two-dimensional x and y value at each sensor load ratio. .) Is a measuring device for obtaining. If a system of the present invention is applied to realize a centroid, it is possible to realize an inexpensive and simple three-dimensional centroid system. Three-dimensional acceleration information is obtained by using the three-dimensional acceleration sensor of the present invention instead of the load sensor. That is, since the human body has a structure capable of different movements for the head, torso, left and right upper limbs, and left and right lower limbs, the three-dimensional acceleration sensor of the present invention is, for example, the top of the head, the cervical spine, and the upper limbs. (Elbow), lower limbs (knee), etc. are attached to the body part suitable for detecting the center of gravity movement. When detecting the twist of the body, it is better to attach to the left and right shoulders. The attachment is fixed with a tape or the like in a form in which a chip-shaped sensor flat surface is in close contact with the surface of the body. Since the mounting directions of the sensors vary, first, the initial orientation of each sensor is detected before starting the inspection in order to enable the earth coordinate conversion of the three-dimensional component of each sensor. Here, the earth coordinates refer to x and y coordinate axes (preferably the front-rear direction and left-right direction of the subject) orthogonal to each other on the horizontal plane, and z coordinate axes set in the vertical direction. When measuring the variation of the center of gravity of the body, the initial position of the part to which each sensor is attached is detected by the earth coordinate system.

  Displacement information of each part is calculated by integrating twice the three-dimensional acceleration information of each part to which the sensor is attached. Since the displacement amount is calculated at the sampling time interval, the instantaneous position for each sampling can be traced by superimposing the displacement amounts sequentially calculated with the initial position as the origin. This information can be obtained for each part of the body. Since the three-dimensional position information of each part is sequentially obtained in this way, by combining these pieces of information, the conventional centroid system only calculates a total COP that does not consider the state of the human body on the plate. However, the system of the present invention can determine the movement of the body and the change of the center of gravity position as three-dimensional information. Further, by summing up the shaking of each part, excluding the z-axis component, a value close to 1 can be calculated as the COP output by the conventional barometer is infinite. If this value is used, it is possible to make a diagnosis in comparison with past data obtained by a conventional apparatus.

The system using the three-dimensional accelerometer of the present invention measures not only the total COP but also the shaking of each part in the posture state of the subject (side bay disease: juvenile, back, hip bending: senile). Can do. The conventional center of gravity meter system uses only the COP value as a diagnostic material for the time being without considering the patient's form (side bay disease: juvenile, back, hip bend: senile), but uses a three-dimensional accelerometer. Since the centimeter according to the present invention can obtain the patient's morphological information, the value can be calculated in consideration of the measurement of the posture, so that more detailed medical care is possible.
The correct posture is directly linked to health, so it is an important diagnostic material and needs attention. The human spine has a gentle S-shaped structure to support gravity and to absorb the shock of moving the body against gravity. Looking at the ideal posture from the side, the gravity line passes through the line connecting the ear, shoulder, hip, knee, and ankle. You can make a correct posture by pulling your chin lightly, stretching your back and knees, and having your head pulled up. This correct posture is supported by the anti-gravity muscle group represented by the spinal column standing muscle and the psoas muscle called the inner muscle. However, after standing for many years, such as housework, fatigue accumulates on the back, causing muscles to crawl and cause senile back and lower back bending. This symptom can be dramatically improved by loosening the tight muscles in the back of the shoulder and loosening the back muscles and ligaments. When this patient is examined with a conventional barometer system, the patient has no significant disturbance in the balance function according to the diagnostic criteria used for evaluation of balance function in otolaryngology etc. Nevertheless, it is judged morbid. However, after the above treatment is performed, the position of the center of gravity moves directly below the cervical vertebra, and the fluctuation of the swing is reduced and stabilized. As a result, it is determined to be normal when an inspection is performed with a conventional barometer system. In this way, an erroneous determination is made that the medical condition has been healed without treatment for balance dysfunction. However, if the centroid system using the 3D accelerometer according to the present invention is used, the change in posture can be quantified, and the posture improvement result can be expressed as a numerical value by shaking the body before and after treatment. It is possible to correctly diagnose that it was not caused by the sway balance function disorder of the center of gravity before the treatment, but simply due to the senile back and waist bending.

  The Example which uses the health-conditions diagnosis system provided with the three-dimensional accelerometer of this invention as a medical condition diagnosis system of a cerebral and nervous system disease or a support system for medication prescription or function recovery training is shown. Conventional diagnosis systems for brain / neurological diseases or support systems for medication prescription or functional recovery training (hereinafter referred to as ART systems) are model figures with pens or fingers on media such as digitizers, tablets, touch panels, etc. (The figure prepared in advance: a straight line, a circle, a square, a sine curve,...). However, the ART system of the present invention can use a three-axis accelerometer to make an inexpensive and simple system. That is, the triaxial acceleration sensor according to the present invention may be attached to the fingertip, and the usage as the ART system can be implemented in such a manner that an imaged model figure is drawn in space. A conventional ART has only two-dimensional information (x, y) obtained by tracing a model figure, but an ART according to the present invention using a three-dimensional acceleration sensor obtains (x, y, z) and three-dimensional information. Can do. To trace a model diagram in space requires space recognition and memory of the size and shape of the model figure, and feedback ability using higher brain functions that realize memory and recognition. Therefore, it is possible to evaluate and train complicated cognitive functions that could not be obtained by conventional ART. In other words, the depth of the parameter can be obtained by obtaining the depth parameter which is not found in the conventional ART.

Since the ART according to the present invention can trace the model figure on the monitor on the paper, it can be used as it is as a conventional ART. Therefore, it is possible to easily compare with past data obtained by the conventional ART.
In addition, it is possible to inspect how an individual image can be realized simply by showing model figures (dogs, cats, circles, squares, stars, etc.) on paper or on a monitor. By quantifying, it is possible to see the effects of medication and training currently in progress. Image training is also possible.

  According to the health condition diagnosis system equipped with the three-dimensional accelerometer according to the present invention, the test form is not limited to standing or sitting on a plate like a heavy body, , Walking stairs, walking on courses with obstacles, sitting on the bed, performing routine exercises such as radio exercises, etc. to grasp body movements in various forms As a result, the range of diagnosis can be expanded and an appropriate health condition can be diagnosed. Moreover, since it can be realized with a configuration of a sensor, a converter and a personal computer, it can be provided in a compact form at a low cost.

  According to the health condition diagnosis system provided with the three-dimensional accelerometer according to the present invention, the movement of each part of the body can be easily grasped, so that the movement of the athlete's body is not limited to the field of health condition diagnosis. It can be easily applied to exploring the movements of people, dancers and actors.
