Detailed Description of the Invention

[0001]

[Table of Contents] The present invention will be described in the following order. Field of Industrial Application Conventional Technology Problems to be Solved by the Invention Means for Solving the Problems (FIGS. 1 and 3) Actions (FIGS. 1 and 3) Embodiments (FIGS. 1 to 6) Effects of the Invention

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an O-ring test device, and in particular, it can be applied to an O-ring test for measuring various physical information such as physical compatibility determination, abnormal site determination, and information identification.

[0003]

2. Description of the Related Art Conventionally, in medical diagnosis, a method called a bi-digital O-ring test (hereinafter referred to as an O-ring test) has been known as a method for diagnosing an abnormal part of a subject as a patient (US Pat. 5,188,107). This is the first finger (thumb) of one hand of the subject and the other second, third, fourth,
One of the 5 fingers that meets the conditions is opposed, and this 2
Make a ring (O-ring) with your fingers and let it continue to exert force. Whereas the examiner tries to open his two fingers from both sides,
Determine the strength of the subject's finger strength to maintain it as it is.

This O-ring test is a biosensor test utilizing the muscle tonus state, and when the subject's finger is pointing at an arbitrary organ representative point, the O-ring opens when the muscle strength of the finger weakens and the organ is abnormal. It means that there is, and when it does not open strongly, it means that it is normal. In the case of the thymus, it means the opposite. This can cause abnormal parts of the body.

When the subject is inspected by holding a sample of a specific substance in his / her hand by the same procedure, if the same substance is present in the living 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 when substances resonate with each other, and is called a resonance test. Using this method, bacteria, viruses, cancer, in vivo metabolites, hormones,
The distribution of neurotransmitters, heavy metals, drugs, etc. in the body can be judged, and diseases can be diagnosed. The O-ring test is an auxiliary diagnostic method performed as a medical examination before the diagnosis by the usual medical latest inspection equipment.

In fact, the O-ring test shows the cure for this disease. In terms of treatment, it is possible to determine the effective drug and determine the optimal dose, the in vivo part of the drug and changes over time, the determination of side effects, and the efficacy and side effects associated with multiple drug combination. Thus, the O-ring test gives useful guidelines for diagnosis and treatment in medical treatment. In practice, it is possible to judge the compatibility of the drug with the body, to judge the abnormal part of the body, and arbitrary and specific objects. It is applied to judge whether and have the same information.

[0007]

By the way, such an O-ring test is formed by fingers of a hand, which is a voluntary muscle that can be controlled by a human being, and there is a possibility that an uncertain factor may enter. For example, a subject who forms an O-ring with two fingers or an examiner who attempts to remove the O-ring may perform an O-ring test with uneven force depending on his or her intention.

[0008] Further, such voluntary muscles tend to cause fatigue, and the force may be adjusted in consciousness, or even if the examinee intends to pull evenly, there is no objective index, so there is a hint effect or other Consciousness may be involved. Therefore, the test results of the O-ring test may not be objectively reliable.

Further, as an apparatus for carrying out this O-ring test objectively, Japanese Patent Application Laid-Open No. 2-136136 (Japanese Patent Publication No. 3-4
The bi-digital O-ring tester disclosed in Japanese Patent No. 4525) is known. By the way, in this bi-digital O-ring tester, since the O-ring is opened by the external pressure generated by press-fitting air into the air bag, the air bag is made flexible so as to expand. However, when the expansion force of the O-ring and the air bladder antagonize each other in the pressurizing process, the air bladder trembles, so that the pressure value at the moment when the O-ring is opened cannot be accurately measured.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose an O-ring test apparatus which allows an examinee to independently perform an O-ring test and to accurately perform an O-ring test. To do.

[0011]

In order to solve such a problem, according to the present invention, an O-ring is formed by the thumb and other fingers of the subject's voluntary muscles, and an external force for opening the O-ring and O In an O-ring test device (1) that measures physical information according to a change in muscle force of a voluntary muscle in a state in which the muscle force of the voluntary muscle of a subject who wants to maintain the ring is antagonized, a shape and a size along the shape of the O-ring are used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 generally indicates an O-ring test apparatus according to an embodiment of the present invention. In this O-ring test apparatus 1, a ratchet 4 is attached to a spring 3 provided in a finger guide 2 having a shape larger than the O-ring and formed along the O-ring formed by the subject's thumb and other fingers. Then, an external force is applied, the external force of the spring 3 is used to open the O-ring of the subject, and after this external force is generated, the thumb and the other finger are separated by the finger pressure sensor 5. The change in muscle force of the voluntary muscle before and after the detected moment is secondarily measured based on the output of the spring pressure sensor 6.

The O-ring test apparatus 1 comprises a finger guide 2, a spring 3, a ratchet 4 and a circuit board 7 (not shown), and the spring 3, the ratchet 4 and the circuit board 7 are housed in the finger guide 2. Has been done. The finger guide 2 is integrally formed of rubber or elastic synthetic resin, and the spring 3
The shape is selected so as to enclose the ratchet 4 and the circuit board 7, and cuts are provided on the upper surface, the outer peripheral portion and the bottom surface of the finger guide 2.

That is, at this cut, the finger guides 2 are partially overlapped with each other, and when the finger guides 2 are gripped,
The cuts of the finger guide 2 are moved in the directions of the arrows shown in FIG. 1 to compress the finger guide 2. Further, a slit 8 is provided on a part of the outer peripheral portion of the finger guide 2,

The spring 3 is disposed in the finger guide 2 substantially in parallel with the ratchet 4. One end of the spring 3 is fixed to the inner peripheral surface of the finger guide 2, and the other end is fixed to the inner peripheral surface of the finger guide 2. It is fixed to the fixed spring pressure sensor 6. Thereby, the external force of the spring 3 that tries to open the O-ring obtained by compressing the spring 3 can be applied to the finger guide 2, and when the external force of the spring 3 is generated, the finger guide 2 expands. Here, the external force applied to the spring 3 is measured by the spring pressure sensor 6, and the resulting analog output signal is transmitted through an analog digital conversion circuit (A) via a connector 12 arranged on a circuit board 7 described later. / D converter) 13
(FIG. 3).

A part of the tip portion 9 of the ratchet 4 protrudes from the slit 8 of the finger guide 2, and the ratchet 4
The end portion of is fixed to the inner peripheral surface of the finger guide 2. Here, when the O-ring test device 1 is in a normal state, only a part of the tip end portion 9 of the ratchet 4 protrudes from the slit 8 as described above, and the finger guide 2 is gripped with a hand to tighten the spring 3 to a predetermined position. 2 is compressed, the entire tip portion 9 of the ratchet 4 pops out of the slit 8 as shown in FIG.
The tip 9 of the ratchet 4 is locked to the finger guide 2 and the spring 3
Expansion is suppressed.

In this case, with the tip portion 9 of the ratchet 4 locked to the finger guide 2, the tip portion 9 of the ratchet 4 is pushed with the thumb and other fingers in contact with the tip portion 9 of the ratchet 4 to unlock the tip portion 9. The extension force of the spring 3 is set so that the pressure of the subject's finger applied to the distal end portion 9 to hold the O-ring and the external force of the spring 3 trying to expand the finger guide 2 antagonize each other. There is. Here, the subject's force to hold the O-ring by forming the O-ring and pushing the tip 9 of the ratchet 4 with the fingertips of the thumb and other fingers differs depending on the subject, and the same subject also forms the O-ring. The O-ring test device according to the subject can be more accurately performed by preparing an O-ring test device in which the extension force of the spring 3 is different.

A finger pressure sensor 5 is provided on the inner peripheral side of the tip portion 9 of the ratchet 4, and the subject presses the tip portion 9 with the thumb and the fingertips of other fingers by the finger pressure sensor 5. When the pressure is measured. In this case, when the tip portion 9 of the ratchet 4 is pushed by the thumb and other fingers, the tip portion 9 of the ratchet 4 that has been locked by the slit 8 is disengaged from the finger guide 2 and the lock is released. Extends and finger guide 2
Tries to expand and a force is generated to open the O-ring of the subject. The analog signal output from the finger pressure sensor 5 is transmitted via the connector 12 to the A / D converter 14
(Fig. 3). Here, regarding the finger pressure sensor 5 and the spring pressure sensor 6, the value of the finger pressure sensor 5 is a predetermined value (for example,
When the pressure exceeds 100 [g]), the measurement is started, and the pressure values of the finger pressure sensor 5 and the spring pressure sensor 6 are integrated time (for example, 5).
During [seconds]), it is taken into the microcomputer described later.

FIG. 3 shows the structure of the circuit board 7. As shown in FIG. 3, the output signals output from the finger pressure sensor 5 and the spring pressure sensor 6 are converted into digital pressure data by the A / D converters 13 and 14 via the connector 12, respectively, and are converted into digital pressure data. (Hereinafter abbreviated as microcomputer) 15 is supplied. The microcomputer 15 includes a central processing unit (CPU) 16, a read-only memory (ROM) 17 in which programs used by the CPU 16 are stored in advance, and a random access memory (RAM) 18 used as a work area in the course of various processes.
And an I / O interface 19 for exchanging various data between the outside and the CPU 16.

An electronic buzzer 20 is provided on the circuit board 7, and the electronic buzzer 20 is detected at the moment when the finger pressure sensor 5 detects that the thumb and the other finger of the subject are separated from each other.
Is designed to ring. This allows the subject to know the end of the O-ring test, so that the subject can independently perform the O-ring test. LCD driver 21
Display data is supplied from the microcomputer 15. As a result, the liquid crystal driver 21 drives the LCD 10 based on this display data, and as a result, the procedure of the O-ring test and its result are displayed on the LCD 10.

That is, as shown in FIG. 4 (A), the LCD
When the outputs of the finger pressure sensor 5 and the spring pressure sensor 6 are displayed as line segments on 10 and it can be determined from the curve of the measured pressure value that it is a factor that causes the measurement to be incorrect (for example, the pressure changes). In the case of not performing), a measurement error (denoted as “ERROR” in FIG. 4) is displayed. Also, the measurement data stored in advance in the microcomputer 15, that is, the pressure value of the spring pressure sensor 6 in a state in which the O-ring is closed with the same force as in normal times (hereinafter referred to as a control state), and the finger pressure sensor 5 Is compared with the pressure value of the spring pressure sensor 6 (when it is considered that the fingertip of the O-ring is separated) when the pressure value of is rapidly decreased, the “O-RING
(-) "," O-RING (+) "," O-RING
The judgment of "(0)" is displayed.

That is, in the O-ring test, as the test result, the muscle tonus of the O-ring of the subject is used to judge the physical compatibility, abnormal site, and information identification. As the state of the O-ring, the current measured value of the spring pressure sensor 6 is smaller than the pressure value (measurement data stored in the microcomputer 15) of the spring pressure sensor 6 in the control state, that is, the O-ring. Open (hereinafter referred to as O-ring minus state, "O-RING (-)" in Fig. 4)
There is a state in which the O-ring cannot be opened. Further, as a state in which the O-ring does not open, the current measured value is larger than the pressure value in the control state, that is, the O-ring is closed with a force stronger than usual (hereinafter, this is referred to as O-ring). This is called the plus state, and "O-RIN" in FIG.
G (+) "and the control state (" O "in FIG. 4).
-RING (0) ").

When the O-ring test apparatus 1 is used,
The electronic buzzer 2 indicates when the O-ring is opened as described above.
The sound is notified to the subject by 0, and the time point when the O-ring is opened and the pressure values before and after the time are displayed on the LCD 8, so that the O-ring test is in the negative state, the control state, or the O-ring. Since the subject can visually judge whether it is the ring plus state, O
The objectivity of the ring test can be secured and the reliability of the test itself can be significantly improved.

In the above configuration, when actually performing the O-ring test, the process is performed based on the O-ring test processing procedure shown in FIG. First, the subject starts from step SP1 and proceeds to step SP2 to determine whether or not to perform the O-ring test. When performing the O-ring test, the subject proceeds to step SP3. At step SP3, the subject holds the O-ring test apparatus 1 with two or more fingers along the finger guide 2 until the tip portion 9 of the ratchet 4 is engaged with the slit 8. As a result, the spring 3 is compressed and the spring 3
External force is applied to try to open the ring.

Next, as shown in FIG. 6, the subject forms an O-ring with his thumb and, for example, his index finger, and brings his thumb and index finger into contact with the tip portion 9 of the ratchet 4. After this preparation is completed, the subject turns on the power switch 11 to instruct the start of the O-ring test. This enables the microcomputer 15
At step SP4, it is determined whether or not the subject has released the locked state by pushing the tip portion 9 of the ratchet 4 with the thumb and forefinger touching the tip portion 9 of the ratchet 4.

When a negative result is obtained, the microcomputer 15 proceeds to step SP8 and ends the processing. When a positive result is obtained, the microcomputer 15 proceeds to step SP5, monitors the output signal obtained from the finger pressure sensor 5, and the pressure value of the finger pressure sensor 5 exceeds a predetermined pressure value (for example, 100 [g]). At this time, the measurement of the pressure values of the finger pressure sensor 5 and the spring pressure sensor 6 is started, and the measurement result is stored in the RAM 18.
Next, the microcomputer 15 proceeds to step SP6 and determines whether or not the measurement time has passed a predetermined time (for example, 5 seconds). If a negative result is obtained, the process proceeds to step SP5, and steps SP5 and SP6 continue until a predetermined time elapses.
Execute the processing loop of.

If a positive result is obtained at step SP6,
The microcomputer 15 proceeds to step SP7 to display the pressure values of the finger pressure sensor 5 and the spring pressure sensor 6 as line segments on the LCD 10 and is also taken into the RAM 18 when the pressure value of the spring pressure sensor 6 sharply decreases. The pressure value of the spring pressure sensor 6 is compared with the pressure value of the spring pressure sensor 6 stored in advance in the ROM 18 in the control state, and when the pressure value taken into the RAM 18 is larger, O- RING (+), O-RING when small
(-), If the same, O-RING (0) is blinked as shown in FIG. 4 (B) to visually notify the subject, and the process proceeds to step SP8 to end the process. Here, based on the measurement value of the spring pressure sensor 6, it is possible to secondarily measure the change in muscle force of the voluntary muscle at the moment when it is detected that the thumb and forefinger are separated.

According to the above construction, the O-ring test apparatus 1 is operated until the tip 9 of the ratchet 4 is locked to the slit 8.
After applying an external force to the spring 3 by compressing the spring 3 by grasping the finger guide 2 with two or more fingers to open the O-ring, the tip portion 9 of the ratchet 4 is moved between the thumb and the index finger. The spring pressure sensor 6 detects the pressure change between the thumb and forefinger when the locking state is released by pushing with a fingertip and an external force is generated, and the thumb and forefinger are separated by the finger pressure sensor 5. The subject can independently perform the O-ring test by secondarily measuring the change in the muscular strength of the voluntary muscles before and after the moment when is detected based on the output value of the spring pressure sensor 6 and displaying it on the LCD 10. It is possible to realize an O-ring test device that can perform the O-ring test accurately.

Further, according to the above-described structure, since the finger guide 2 is made of rubber or elastic synthetic resin, the external force of the spring 3 can be stably generated. Even if a test is performed, the correct judgment result can be obtained.

In the above embodiment, the pressure values of the finger pressure sensor 5 and the spring pressure sensor 6 are displayed as line segments on the LCD 10, but the present invention is not limited to this, and the finger pressure sensor is not limited thereto. 5 and the pressure value of the spring pressure sensor 6 are displayed, for example, in a bar graph, numerical values are displayed, and the resulting O-ring state, that is, the O-ring minus state, the control state, the O-ring plus state, or the like is displayed. Even if various display means and display methods such as displaying as characters are used, the same effect as the above-described embodiment can be obtained.

In the above embodiment, the case where the finger guide 2 made of rubber or elastic synthetic resin is used has been described, but the present invention is not limited to this, and it can be used before and after the moment when the O-ring is opened. If the pressure value can be detected accurately,
