Description

[0001] The present invention will be described in the following order. Industrial Application Field Means for Solving the Problems to be Solved by the Conventional Technical Invention (FIGS. 1 to 3) Operation (FIGS. 1 to 3) Embodiment (FIGS. 1 to 17) (1) Implementation Example voluntary muscle strength measuring device (FIGS. 1 to 6) (2) Method of judging body suitability by voluntary muscle strength measuring device (FIGS. 2, 7 to 13) (3) Method of judging abnormal part by voluntary muscle strength measuring device (FIG. (2, 14 and 15) (4) Information identification method using voluntary muscle strength measuring device (FIGS. 2, 16 and 17) (5) Effects of other embodiments of the present invention The present invention relates to a voluntary muscle strength measuring device, and is particularly applicable to a device for measuring a voluntary muscle strength when an examiner opens a ring shape formed by a first finger and another finger of a subject's hand. Conventionally, in medical diagnosis, a method called a bi-digital O-ring test (hereinafter, referred to as an O-ring test) is known as a method for diagnosing an abnormal site of a patient who is a patient (for example). U.S. Pat. No. 5,188,107). This means that the first finger (thumb) of one hand of the subject
One finger that satisfies the condition among the four or five fingers is opposed to each other, and a ring (O-ring) is formed with the two fingers to continuously apply force. While the examiner tries to open two fingers with fingers from both sides, the strength of the test subject's finger force to be maintained as is is determined. That is, the O-ring test is a living body sensor test utilizing the muscle tonus state. When the muscular strength of the finger points to an arbitrary organ representative point and the muscular strength of the finger weakens, the O-ring opens, meaning that the organ is abnormal. On the contrary, when it does not open strongly, it means that it is normal. But only in the case of the thymus means the opposite. With this, you can find the abnormal part of the body. [0005] Further, when the same procedure is used to carry out a test while holding a sample of a specific substance in the hand, if the same substance is present in the body of the subject, the muscle strength of the finger becomes weak and the O-ring opens. This is interpreted as a phenomenon that occurs due to resonance between substances, and is called a resonance test. Using this method,
The distribution of bacteria, viruses, cancers, metabolites in the body, hormones, neurotransmitters, heavy metals, drugs and the like in the body is determined, and the disease can be diagnosed. The O-ring test is an auxiliary diagnostic method that is performed as a medical examination before a diagnosis is performed by a normal medical latest testing device. Actually, in the O-ring test, it is possible to find out what kind of abnormalities exist in which organ by examining the subject. First, in terms of diagnosis, detection of abnormal body organs and drawing (imaging) on the body surface, search for the cause of abnormal parts, diagnosis of bacteria, viruses, and early cancer and diagnosis of localization, metabolites in vivo, hormones, neurotransmitters Imaging and the like, and assist in diagnosis of the cause of chronological changes and various diseases, particularly electromagnetic waves and heavy metal deposition. Next, an O-ring test shows a cure for this disease. On the therapeutic side, the determination of the effective drug and the optimal dose, the biodistribution and time course of the drug, the determination of side effects,
Evaluate the efficacy and side effects of multiple drug combinations. As described above, the O-ring test provides a useful guideline for diagnosis and treatment in medical care, and in practice, it determines the suitability of a drug or the like to the body, the determination of an abnormal site in the body, and any target and a specific target. This is applied to the determination of whether or not have the same information. [0008] Incidentally, the O-ring test is formed by fingers of hands, which are voluntary muscles that can be controlled by human beings, and there is a possibility that uncertain factors may enter the O-ring test. For example, a subject who forms an O-ring with two fingers or an examiner who tries to remove the O-ring may perform the O-ring test with a non-uniform force depending on his / her intention. In addition, such voluntary muscles are apt to feel fatigue, and may increase or decrease power in consciousness. Therefore, the test result of the O-ring test may not be reliable from an objective point of view. The present invention has been made in view of the above points, and an object of the present invention is to propose a voluntary muscle strength measuring device capable of measuring voluntary muscle strength with high reliability. According to the present invention, a ring shape 6 formed by a first finger and another finger of a subject's hand is formed by a voluntary muscle when an examiner opens the subject. In the optional muscular strength measuring device 1 for measuring muscular strength of a subject, a first sensor 2 arranged at least in one place of two fingers and detecting a muscular strength when an examiner opens a ring shape is arranged between two fingers and between two fingers. There is provided a second sensor 3 for detecting whether or not the finger is separated, and a muscle strength measuring means for measuring a muscle strength at the time when the two fingers are separated by the detection outputs of the first and second sensors 2 and 3. did. The first finger arranged at least one of two rings of the ring shape 6 formed by the first finger and the other finger of the subject's hand. The sensor 2 detects the muscle force when the examiner opens the ring shape 6 and the second sensor 3 disposed between the two fingers detects whether the two fingers are separated from each other. By measuring the muscular strength at the time when two fingers are separated by the detection outputs of the first and second sensors 2 and 3, voluntary muscular strength can be measured with high reliability. An embodiment of the present invention will be described below in detail with reference to the drawings. (1) Apparatus for Measuring Voluntary Muscle Strength in the Embodiment In FIG. 1, reference numeral 1 denotes an apparatus for measuring voluntary muscle strength according to the present invention as a whole, and sensor outputs of two pressure sensors 2 and 3 are input to a dynamic strain measuring device 4. Have been. The output of the dynamic strain measuring device 4 is connected to a pen recorder 5 so that a change in pressure detected by the pressure sensors 2 and 3 can be recorded on paper. In this embodiment, the pen recorder 5 is selected to have two channels in order to record changes in the pressures of the pressure sensors 2 and 3 simultaneously. Each of the pressure sensors 2 and 3 is a small and thin pressure transducer using a foil strain gauge as a transducer and forming a bridge inside the transducer. For example, the thickness is 0.6 [mm] and the diameter is 6 [mm]. mm]. As shown in FIG. 2, one pressure sensor 2 is mounted near the second joint of the finger on which the O-ring 6 of the subject is formed, and the other pressure sensor 3 is mounted so as to be sandwiched between the fingertips of the subject on which the O-ring 6 is formed. Can be The pressure sensor 2 is attached to the surgical tape 7 in advance so that the pressure sensor 2 can be easily attached, and the pressure sensor 3 is attached to the sheet material 8. In practice, with the pressure sensors 2 and 3 mounted as shown in FIG. 2, the examiner places the O-ring 9 of the examinee on the O-ring 6 of the subject as shown in FIG.
And perform an O-ring test. As a result, the changes in the muscular strength of the finger, that is, the voluntary muscular strength measured by the pressure sensors 2 and 3, are obtained as graphs g1 and g2 as shown in FIG. Actually, the graph g1 of the pressure sensor 2 shows the pressure change when the O-ring 6 of the subject is pulled by the O-ring 9 of the examiner, and the graph g2 of the pressure sensor 3 shows the fingertip of the O-ring 6 of the subject. It indicates when you left. Here, in the O-ring test, the body suitability, an abnormal site, information identification, and the like are determined based on the O-ring state of the subject as a test result. There are a state where the O-ring is not opened and a state where the O-ring is opened (hereinafter, this is referred to as an O-ring minus state). Further, the state in which the O-ring is not opened includes a state in which the O-ring is closed with a stronger force than normal (hereinafter referred to as an O-ring plus state) and a state in which the O-ring is closed with the same force as normal (hereinafter referred to as a control state). There is). In the case of the voluntary muscular strength measuring apparatus 1, the graphs g1 and g2 of FIG. 4 are analyzed by dividing them into five sections a, b, c, d and e as shown in the figure. That is, in the first section a, the examiner starts to pull the O-ring 6 of the subject with the O-ring 9 while the finger of the O-ring 6 of the subject is closed. Further, the second section b is the moment when the fingertip of the O-ring 6 of the subject is separated, and the examiner similarly applies a force to pull the O-ring 6 of the subject. Further, the third to fifth sections c are periods during which the finger of the O-ring 6 of the subject is open, and in the third section c, the examiner applies a force to pull the O-ring 6 of the subject, and the fourth section c is the fourth section. Is the moment when the examiner applies the maximum force. Furthermore, in the fifth section e, the tester finishes pulling the O-ring 6 of the subject. Comparing the graphs g1 and g2 between the control state and the O-ring minus state, the O-ring minus state has the following characteristics. That is, first, when the pressure value p in the second section b of the graph g1 in the case of the control state and the case of the O-ring minus state are compared, the value is smaller in the O-ring minus state than in the control state. Second section b
Is the moment when the fingertip of the O-ring 6 of the subject is separated,
The pressure value p in the section b can be determined as a force required to release the fingertip of the O-ring 6 of the subject. When this value is lower than the control state when the O-ring is in the minus state, it means that the muscle strength of the O-ring 6 of the subject is reduced when the O-ring is in the minus state. When the area surrounded by the X axis, the pressure curve in the graph g1 and the straight line extending perpendicularly from the section b to the pressure curve is s, and the area s in the control state and the O ring minus state is compared, The area s is smaller in the minus state. This area s is the integral of the force until the fingertip separates when the force is applied to the O-ring 6 of the subject. O
If the subject has a decrease in muscular strength in the ring minus state, the fingertip opens quickly with the same force, so the area s is small. Further, the down slope in the section e is different between the control state and the O-ring minus state. This is a state of pressure change after the force applied to the O-ring 6 of the subject has passed the maximum point. In the case of the control state, the state in which the force of the subject's finger and the force of the examiner's finger continue to antagonize, followed by a process of weakening according to the examiner's intention to end the measurement. Looking at this with a pressure curve, it follows a trajectory in which a pressure value near the maximum pressure continues for a while and then decreases. It is characteristic that the pressure value near the maximum value continues flatly. On the other hand, when the O-ring is in the minus state.
Since the subject's finger opens as soon as the maximum pressure is applied, the trajectory follows that the pressure drops immediately after the maximum point in the pressure curve. FIG. 5 shows the measurement results in the actual control state, and FIG. 6 shows the measurement results in the O-ring minus state. FIGS. 5 and 6 show an example of determination of physical compatibility as an O-ring test. In FIG. 5, a test subject is caused to hold a lifestone in one hand as a substance having high physical compatibility, and the finger is used by the other hand. The case where an O-ring test is performed on the formed O-ring 6 is shown, whereby the control state is measured. FIG. 6 shows a case in which a subject holds arsenic in one hand as a substance having low physical compatibility and performs an O-ring test with an O-ring 6 formed by the fingers of the other hand, thereby obtaining an O-ring minus. The condition is being measured. From each of the figures, the pressure value p in the section b is about 200 g / cm ^{2 in the} control state, and about 100 g / cm ^{2 in} the O-ring minus state. It can also be seen that the area s is wider in the control state than in the O-ring minus state. Further, it can be seen that the difference in the gradient in the section e is that the value near the maximum value continues in the case of the control state, while the gradient decreases after the maximum value in the case of the O-ring minus state. According to the above configuration, the O formed by the subject
When measuring the muscle strength of the finger when the examiner opens the ring 6,
Pressure sensor 2 arranged at one position of the finger of the O-ring 6 of the subject
Thus, the examiner detects the muscular strength at the time of opening the O-ring 6 of the subject, and checks whether the two fingers of the O-ring 6 of the subject are separated by the pressure sensor 3 arranged at the fingertip of the O-ring 6 of the subject. Is detected and the muscular strength at the time when the two fingers of the O-ring 6 of the subject are separated is detected based on the detection outputs of the pressure sensors 2 and 3, thereby preventing the influence of disturbance. Thus, it is possible to realize a voluntary muscle strength measuring device capable of accurately and objectively detecting the muscle strength acting in the O-ring test. (2) Method of Determining Physical Fitness Using Voluntary Muscle Strength Measurement Apparatus A description will now be given of a method of determining physical fitness using the above-described voluntary muscle strength measurement apparatus 1 to determine fitness with respect to a specific subject. In this embodiment, a telephone card, a ginseng, a card with an arrow pointing in the direction of the fingertip, and a card with an arrow pointing in the body direction are used as specific objects, and these specific objects match the subject. It is determined whether or not. In practice, this physical compatibility determination method is executed in a physical compatibility determination procedure RT0 as shown in FIG. That is, first, in this body suitability determination method, an O-ring test is performed in a normal state in step SP1.
The muscular strength at this time is measured by the optional muscular strength measuring device 1. In this case, as shown in FIG. 8A, a state in which nothing is placed on the left hand of the subject is set to a normal state, and the muscular strength obtained by the pressure sensors 2 and 3 is measured by the voluntary muscular strength measuring device 1 at this time. At this time, the pressure sensor 2 attached to the surgical tape 7 is attached to the vicinity of the second joint of the finger, as described above with reference to FIG.
The other pressure sensor 3 is attached so as to be sandwiched between fingertips. Next, in step SP2, an O-ring test is executed in a state where a specific target is specified. This is Figure 8
As shown in (B), a specific object 10 such as a telephone card, a ginseng, a card with an arrow pointing in the direction of the fingertip, or a card with an arrow pointing in the body direction is placed on the left hand of the subject. At this time, the muscular strength obtained by the pressure sensors 2 and 3 is measured by the optional muscular strength measuring device 1. Then, in step SP3, the above-mentioned steps SP1 and SP2
The suitability of the specific subject 10 to the subject is determined by comparing the muscular strengths measured in the above. FIG. 9 shows an output in a normal state, that is, a control state, as an experimental example of the body suitability judging method. On the other hand, FIG. 10 shows an output in a state where a telephone card is placed, that is, an O-ring minus state.
FIG. 11 shows a state in which a card with an arrow directed toward the inside of the body is placed, that is, an output in an O-ring minus state, and indicates that the body is not suitable in any case. FIG.
2 shows an output in a state in which a card with an arrow pointing toward the fingertip side is placed, that is, an output in an O-ring plus state, and FIG. 13 shows an output in a state in which ginseng is placed, that is, an O-ring plus state. To indicate that In this experimental example, the control state and O
Even in the ring plus state, the O-ring 6 of the subject's fingertip is open, but the pressure applied when the fingertip of the O-ring 6 is released is 150 to 250 g in the control state.
/ cm ² ], and a value of 100 to 250 [g / cm ² ] in the case of the O-ring minus state on which the telephone card is mounted.
When the O-ring on which the card with the arrow pointing toward the inside of the body is placed is in the minus state, the O-ring has a value of 100 [g / cm ² ] and the O-ring with the card on which the arrow pointing toward the fingertip is placed It takes a value of 300 g / cm ^{2 in the} plus state, and 200 g / c in the O-ring plus state with ginseng.
m ² ]. Here, for example, the pressure in the control state is
If it is set to 200 [g / cm ² ] and the portion larger than this is set to the O-ring plus state, and the smaller portion is set to the O-ring minus state, the result matches the O-ring test result, and the pressure in the control state is actually obtained properly If it can be done, it can be understood that the result of the O-ring test matches the force applied when the fingertip of the O-ring is separated. According to the above configuration, the voluntary muscle strength measuring device 1
Is used to measure the muscular strength when the fingertip of the O-ring 6 of the subject is separated in a normal state, and the muscular strength when the fingertip of the O-ring 6 is separated when a specific target is instructed. By comparing the muscular strengths of the subjects to determine the suitability of a specific subject to a subject, an O-ring test can be performed accurately and objectively and the body suitability can be determined with high reliability. A judgment method can be realized. (3) Method of Determining Abnormal Part Using Voluntary Muscle Strength Measurement Apparatus A description will now be given of an abnormal part determination method for determining an abnormal part of the subject's body using the above-described voluntary muscle strength measurement apparatus 1. In this embodiment, the subject himself / herself instructs a body organ from outside with a wooden pointing rod, and determines whether or not the organ is abnormal. In practice, this abnormal part determination method is executed in an abnormal part determination procedure RT10 as shown in FIG. That is, in this abnormal part judging method, an O-ring test in a normal state is executed in step SP11, and the muscular strength at this time is measured by the voluntary muscular strength measuring device 1. This means that, as shown in FIG. 15A, a state in which the left hand of the subject does not give any instruction is a normal state, and the muscular strength obtained by the pressure sensors 2 and 3 at this time is the voluntary muscular strength measuring device 1.

Next, at step SP12, an O-ring test is executed in a state where a predetermined organ of the body is pointed. In this case, as shown in FIG. 15B, the subject holds the wooden pointing rod 20 with his left hand to instruct an organ of the body to perform an O-ring test. At this time, the muscular strength obtained by the pressure sensors 2 and 3 is measured. It is measured by the voluntary muscle strength measuring device 1. And step SP
In step 13, the aforementioned steps SP11 and SP1
By comparing the muscle strengths measured in step 2, it is determined whether the designated organ is abnormal based on whether the O-ring is in the minus state, the control state, or the O-ring plus state. According to the above-described configuration, the muscular strength when the fingertip of the O-ring 6 of the subject is separated is measured in a normal state using the voluntary muscular strength measuring device, and the muscular strength when the predetermined part of the body is instructed is measured. The O-ring test is performed accurately and objectively by measuring the muscle strength when the fingertip of the ring 6 is separated and comparing the muscle strengths based on the measurement results to determine whether or not a predetermined part of the body is abnormal. And an abnormal part determination method capable of determining an abnormal part of the body with high reliability can be realized.

In practice, this information identification method is executed by an information identification procedure RT20 as shown in FIG. That is, in this information identification method, first, in step SP21, the state is determined in such a manner that the object is in contact with a specific object.
A ring test is executed, and the muscular strength at this time is measured by the optional muscular strength measuring device 1. In this case, as shown in FIG. 17A, the state in which the subject holds the specific target 30 in the left hand is set to a normal state, and the muscle strength obtained by the pressure sensors 2 and 3 at this time is measured by the voluntary muscle strength measuring device 1. . At this time, the O-ring 6 formed by the right hand of the subject is attached to the surgical tape 7 near the second joint of the finger and one pressure sensor 2 is attached to the O-ring 6 as described above with reference to FIG. , The other pressure sensor 3 is attached. Next, in step SP22, an O-ring test is executed in a state where an arbitrary target is pointed while touching a specific target. As shown in FIG. 17 (B), as shown in FIG. 17 (B), the subject holds the specific target 30 with the left hand, and further causes the wooden pointing stick 31 to point to any target 32 to 34.
An O-ring test is performed each time, and at this time, the muscular strength obtained by the pressure sensors 2 and 3 is measured by the optional muscular strength measuring device 1. Then, in step SP23, the above-described step SP
By comparing the muscle strength measured in step 21 and step SP22,
The object having the same information as the specific object 30 among the arbitrary objects 32 to 34 indicated by the pointing rod 31 is determined as the O-ring minus state, the control state, or the O-ring plus state. According to the above-described configuration, the O-ring 6 at the time when it comes into contact with the specific object 30 using the voluntary muscle strength measuring device is used.
