Description

  The present invention relates to a living body contact type acoustic vibration device. Specifically, the present invention relates to a living body contact type acoustic vibration device that generates vibrations while directly propagating vibrations based on acoustic signals to the surface of a living body.

A so-called ultrasonic diagnostic apparatus is known today as an application of elastic vibration waves to the medical field. For example, there is an ultrasonic therapy device (Sonic Accelerated Fracture Healing System: SAFHS) manufactured by Smith and Nephew. When an ultrasonic wave is irradiated on a living body, it is transmitted into the living body and reflected by the living tissue, so that the living body tissue can be observed by measuring the reflected ultrasonic intensity. In addition, ultrasonic waves are so-called elastic waves, and it is known that by irradiating pulsed ultrasonic waves, especially as a form of mechanical energy, bone healing is promoted and has already been commercialized. The ultrasonic output conditions for promoting such fusion are set to an ultrasonic frequency of about 1.5 MHz, an ultrasonic output of 30 mW / cm ² , an irradiation time of 20 minutes, and the like.

  As a treatment method using non-invasive mechanical vibration, a cycloidal vibration technology (CVT) is known. This method uses a special motor to generate non-impact vibrations three-dimensionally on the surface. The amplitude of the vibration used at this time is about 0.1 to 0.5 mm. The frequency range is about 15 to 75 Hz. Recently, results have been reported for bedsore treatment using this CVT.

In this study, 600, 800, and 1000 mVpp were used as vibration intensities at a frequency of 47 Hz and applied to the ears of anesthetized male mice. The result was that blood flow increased due to vibration at 47 Hz. It has also been shown that tissue causing bed slippage is normalized by the effect of increased blood flow (see Non-Patent Document 1).
Similar studies have been conducted for some time, and it has been reported in rabbit experiments that blood flow increases in 1-2 minutes for psycholoidal vibration at 22-62 Hz (see Non-Patent Document 2).

  Similarly, the effect on lymph flow using this CVT has also been studied. By applying CVT, regeneration of fine lymphatic vessels important in wound healing is observed, and the cut veins and lymphatic vessels regenerate in 9 to 13 days, and lymph can easily flow and edema is reduced. Have been reported (see Non-Patent Document 3).

  However, the psychocolloidal vibration device has a problem that it cannot be manufactured at low cost because it requires a considerably complicated motor control.

  On the other hand, audible sound also acts as elastic waves. The interaction between a sound wave and a living body is generally heard as sound through hearing. Specifically, it begins with a conversation between people, and sounds are also generated by enjoying music or speaking, and listening to the sounds is part of the general human behavior. At the same time, animals are also known to make sounds and communicate with each other. In this way, sound has a very important meaning in humans and animals. In recent years, the genre of music therapy has developed.

  When listening to music, one is by sound waves propagating in the air, and the other is so-called bone conduction (bone conduction) in which direct vibration from the instrument propagates to the auditory system. This type of means is known as so-called body sonic. The body sonic method is a listening system that listens to music while letting the body experience the acoustic sound vibrations by using an electrical-mechanical vibration converter to convert mainly low-frequency components of music at the same time as audible sounds (non-patent literature). 4, see Patent Document 1 and Patent Document 2).

  This body sonic device is used in music therapy, and in this music therapy, auditory sense or body sensation vibration that applies vibration waves to the entire body or a wide range is used.

  A living body contact type acoustic vibration device (hereinafter, simply referred to as “vibration device”) using sound according to the present invention includes a vibration generation unit including a vibration member that converts an externally input acoustic signal (electrical signal) into vibration. And a fixing means for tightly fixing the vibration generating means to the living body part of the wearer, and the vibration generated by the vibration generating means is propagated to the living body part. Here, “external” in the vibration device of the present invention means the outside of the vibration device, and corresponds to, for example, a sound reproducing means described later.

  In the vibration device of the present invention, the local blood flow and lymph flow of the affected part can be improved by propagating vibration based on the acoustic signal to the wearer's living body part (affected part) in a close contact state. , Local pain in the affected area can be resolved. Examples of the site to which the vibration device of the present invention is applied include hands such as wrists, elbows, arms and shoulders, and legs such as ankles, calves, knees and thighs, waists and necks.

  Hereinafter, each means which comprises the vibration apparatus mentioned above is demonstrated concretely.

[Vibration generating means]
The vibration generating means is means for generating vibration based on an acoustic signal input from the outside and propagating the generated vibration to a wearer's living body part (affected part). The vibration generating means is preferably a planar means having flexibility. As a result, the vibration generating means is fixed in close contact with the affected part even if the affected part of the wearer is bent or in a state where the wearer is bent, and even when the wearer bends and stretches, the contact state is maintained without peeling off. Is done. Here, as a thickness of a vibration production | generation means, it is about 2-20 mm, for example, it is preferable that it is about 3-15 mm, and it is more preferable that it is about 3-10 mm.

  The number of vibration generating means provided in the fixing means is not limited to one, and a plurality of vibration generating means may be provided. In the vibration device of the present invention that converts an acoustic signal into vibration, the range to which vibration is applied may vary depending on the affected area. For example, in the case where a pain is generated locally at one place, it is often sufficient to provide one vibration generating means on the fixing means. On the other hand, when applying vibration to a predetermined region, it is preferable to provide a plurality of vibration generating means on the fixing means. In the case where a plurality of vibration generating means are provided, for example, when the fixing means is strip-shaped, it is preferable to arrange a plurality of vibration generating means in a row along the bending direction of the fixing means. Thereby, while being able to wind around a wearer's affected part becomes easy, the adhesiveness of a vibration generator can be improved. Further, the vibration generating means may be arranged in a matrix on the fixing means. As a result, the vibration device has flexibility in the vertical direction and the horizontal direction, and even when the surface of the affected area of the wearer has irregularities or bends, the vibration generating means is more closely attached to the affected area of the wearer. It can be fixed, and the wearer can be prevented from peeling off due to bending and stretching movements. That is, the fixing means provided with the vibration generating means maintains the close contact state with the wearer by changing the form in accordance with the wearer's state and operation.

  In addition, as a shape of one vibration generating means (comprising one or a plurality of vibration members), for example, a rectangular shape whose length and width are about 50 to 300 mm, preferably about 100 to 200 mm, respectively, Examples include a circular shape of about 5 to 300 mm, preferably about 100 to 200 mm, and various shapes from a large shape to a small shape can be given. By setting the size of the vibration generating means to a size that covers only the affected part of the wearer, the adhesion can be further enhanced and vibration can be concentrated and applied locally.

  Here, in order to propagate vibration more efficiently in the living body, it is preferable to obtain impedance matching between the vibration generating means and the living body part (affected part). Such impedance matching can be obtained by applying an appropriate substance between them. As an appropriate substance, for example, a substance having an intrinsic acoustic impedance (product of sound speed and density) close to that of a living body, and a jelly-like substance (echo jelly) used for an ultrasonic diagnostic apparatus can be used. By using such a substance, air can be prevented from being mixed between the vibration member and the living body part, and as a result, vibration can be efficiently propagated.

[Vibration member]
The vibration member is a member that converts an acoustic signal into vibration, and the vibration generation unit may constitute the vibration generation unit, but is usually disposed and protected, for example, inside the vibration generation unit. When the acoustic signal is input, the acoustic signal is converted into vibration, and the vibration based on the acoustic signal is propagated to the affected part of the wearer (vibration is applied). Thereby, in the affected part which received the vibration, local blood flow and lymph flow improve, and effects such as local pain are eliminated. Thus, in the present invention, the vibration member (vibration generating means) is closely fixed to the affected part of the wearer, the acoustic signal is transmitted to the vibration member, and the vibration member is in close contact with the affected part, and is converted into vibration. By suppressing fluctuations such as vibration attenuation, it is possible to accurately and reliably apply a vibration having a preferred strength directly to the affected area.

  Moreover, it is preferable that the vibration member is configured to generate a sound that can be heard by the wearer while generating a vibration based on the sound signal when the sound signal is input. In other words, the vibration member applies vibration to the affected area of the wearer and generates sound that can be heard by the wearer. Here, the sound that can be heard by the wearer refers to, for example, sound in a frequency range of 20 Hz to 25 kHz, and preferably includes a frequency component in a range of 200 Hz to 18 kHz.

  Thereby, a wearer can obtain a relaxation effect by an acoustic effect while receiving vibration in an affected part, As a result, the healing effect of an affected part can be raised synergistically. In addition, because it can be treated while listening to music, the mental burden on the treatment is reduced, and it is possible to enjoy the treatment for a predetermined time without feeling painful, and repeated treatment is equally painful. Can be done without.

  When using the vibration device of the present invention, the intensity of the sound emitted from the vibration member is about 40 to 100 dB SPL (Sound Pressure Level) as a sound volume at a position approximately 1 m away from the fixed position of the vibration member. Preferably, it is about 60 to 90 dB SPL. With such a sound intensity, a desired amplitude can be obtained, and the effects of the present invention are particularly prominent. In the vibration device of the present invention, it is preferable to select an amplifier capable of generating such a sound intensity.

Here, in the electro-mechanical vibration converter, when the sound pressure generated by the vibration generating means such as a diaphragm or a dynamic speaker is 60 to 90 dB, how much the diaphragm or the like can be moved to obtain a predetermined amplitude is calculated. It is possible to ask. The larger the sound pressure due to mechanical vibration, the greater the generated amplitude.
As is well known, the sound pressure is proportional to the speed of the diaphragm, but if the displacement is x (t) = x _m sinωt,
Speed is
V (t) = dx / dt = ωx _m cos ωt
So
Absolute sound pressure is
| P | = ω ² ρa ² / 2√2 × x _m
Incidentally, x _m denotes the amplitude, omega represents the angular velocity, t indicates time.
Using this equation, the amplitude required to determine the sound pressure in decibels can be calculated.
For example, when the frequency is 1 kHz, the diameter of the dynamic speaker is 2 cm, and the absolute sound pressure at a position approximately 1 m away from the sound source (fixed position of the vibration member) is 80 dB, the amplitude of the vibrator is 1.2 mm. can get. Therefore, when this amplitude is transmitted to the living tissue, a sound wave having an amplitude of 1.2 mm is transmitted to the body. It can be seen that when the absolute sound pressure is constant, the amplitude decreases as the frequency increases, and increases as the frequency decreases.

As an example, Table 1 shows an example of calculation results when the frequency is 1 kHz and 5 kHz when the absolute sound pressure is 80 dB and 60 dB.
However, the aperture of the speaker was 2 cm (a = 0.01 m) and ρ (air density) = 1.184 kg / m ³ .
Oscillator amplitude at each sound pressure (calculation results)

  Thus, when the frequency of the sound obtained from the sound source is changed, the amplitude of the vibrator is changed accordingly, and the amplitude of the sound wave transmitted to the body is changed.

  The above-described vibration member may be three-dimensional or planar, but it is preferable to use a flexible diaphragm (planar member). By bringing the surface of the diaphragm directly into contact with the affected area, vibration (vibration wave) generated by the vibration member can be directly propagated (introduced) into the living body, and the effects of the present invention are more effective. Can enjoy. Specifically, the vibration member is preferably a ceramic diaphragm made of a thin and strong material. As a three-dimensional speaker, a dynamic speaker in which a vibrating body is loosely coupled directly to a coil surface can be cited.

  The number of vibrating members is not limited to one, and a plurality of vibration generating means may be provided. When the vibration generating means includes a plurality of vibration members, the vibration members are preferably disposed along the bending direction of the vibration generating means (fixing means). By disposing a plurality along the bending direction, the flexibility of the vibration generating means is maintained, and higher adhesion can be ensured. Here, the bending direction is a direction in which the vibration generating means (fixing means) is bent, and in the case where the vibration generating means is formed in a band shape, it indicates the longitudinal direction of the band shape. In particular, it is preferable to arrange the rectangular diaphragm along the bending direction of the vibration generating means (fixing means) so that the side in the bending direction is a short side (see FIG. 2).

  Examples of the shape of the vibration member include various shapes such as a polygonal shape such as a rectangle and a circular shape. For example, a rectangular shape having a vertical and horizontal length of about 10 to 150 mm, a circular shape having a diameter of about 10 to 150 mm, and the like, and a rectangular shape having a length of about 10 to 40 mm and a width of about 60 to 120 mm are preferable. . Moreover, as thickness of a vibration member, it is about 0.1-15 mm, for example, it is preferable that it is about 0.1-5 mm, and it is more preferable that it is about 0.3-2 mm. By using such a vibration member with a size and thickness that is appropriately disposed, the vibration generation means is closely fixed to the affected part of the wearer without impairing the flexibility of the vibration generating means, and the vibration is directly and reliably transmitted. can do.

  Moreover, when there are a plurality of vibrating members, it is preferable that the vibrating members are electrically connected in parallel. By electrically connecting the vibrating members in parallel, the same amount of current is supplied to each vibrating member, and the same magnitude of vibration is generated in each vibrating member. Thereby, the vibration generating means can apply vibration uniformly in the plane.

[Fixing means]
The fixing means is for tightly fixing the vibration generating means to the affected part of the wearer, and the vibration generating means including the vibration member is attached. The fixing means is preferably composed of a flexible cloth, metal, resin material, leather, or the like, and more preferably has elasticity. Thereby, while being able to improve the adhesiveness to the affected part of a vibration generation means, it can fix to an affected part reliably. The shape of the fixing means is not particularly limited, and can be, for example, a polygonal shape such as a rectangle or a circular shape. For example, the vibration generating means is closely fixed to the affected area of the wearer by forming the fixing means in a band shape (rectangular shape) and winding the fixed means around the affected area (arm, leg, waist, etc.) of the wearer. Can do. In addition, the vibration generating means can be tightly fixed to the affected area of the wearer by forming the fixing means in a polygonal shape or a circular shape and sticking this fixed means to the affected area (back, palm, etc.) of the wearer. .

In the vibration device of the present invention having the above-described configuration, when an acoustic signal is input from the outside, the vibration member oscillates due to the acoustic signal and generates a vibration wave based on the acoustic signal. This vibration wave is propagated to the affected part of the wearer to which the vibration device is closely fixed, and vibration based on the acoustic signal is applied to the affected part. Thereby, blood flow and lymph flow improve in the affected part of the wearer who received vibration. Further, when the frequency and sound pressure of the vibration wave generated by the vibration member are within a predetermined range, the vibration wave is recognized as sound by the wearer's hearing.
The application time of the vibration device is preferably about 5 to 180 minutes, more preferably about 5 to 120 minutes, and further preferably about 15 to 60 minutes. In the vibration device of the present invention, no abnormality was observed even when the usage time exceeded 8 hours.

  According to the vibration device of the present invention, the wearer can listen to the sound based on the acoustic signal, and can receive the vibration based on the acoustic signal locally and directly in the affected area in a relaxed state. The affected area can be treated, and as a result, an unprecedented therapeutic effect can be obtained. The effect of transmitting acoustic waves to the site complaining of pain is that the pain is temporarily resolved after the acoustic wave is applied, so that the flow of blood and lymph fluid increases, so that the function of living tissue at that site is increased. Is considered to be due to a temporary improvement.

  Specifically, since a minute blood vessel and a lymph vessel are included in the biological tissue directly subjected to vibration, these blood vessel and lymph vessel vibrate simultaneously with the vibration of the biological tissue. As a result, vascular resistance of blood vessels and lymphatic vessels is expected to decrease. Also, the vibration (vibration wave) waveform changes due to the change of the input acoustic signal. When the frequency component of the acoustic signal is low, the vibration waveform (amplitude) becomes large and the frequency component of the acoustic signal is high. In the case of the region (high frequency), the vibration waveform (amplitude) becomes smaller, and various vibrations can be obtained at random. The pipe resistance consists of frictional resistance and inertial resistance.

[Bio-acoustic acoustic vibration system]
Next, a bio-contact acoustic vibration system including the above-described bio-contact acoustic vibration device will be described. The biological close-contact type acoustic vibration system includes an acoustic reproduction unit that reproduces an acoustic signal, an amplification unit that amplifies the acoustic signal reproduced by the acoustic reproduction unit, and the acoustic signal amplified by the amplification unit. And a living body contact type acoustic vibration device. This biological close-contact type acoustic vibration system may include a sound source that can be reproduced by the sound reproducing means.

[Body-contact acoustic vibration device]
The living body contact type acoustic vibration device is a characteristic component of the present system. The description of the biological close-contact type acoustic vibration device is omitted because it overlaps with the above description.

[Sound reproduction means]
The sound reproducing means is a means for reading a sound source (acoustic data) and reproducing an acoustic signal (electrical signal), and the sound signal reproduced by the sound reproducing means is output to the amplifying means. As an apparatus provided with this sound reproducing means, for example, an electronic device capable of reproducing music such as a CD radio cassette, a CD player, an HDD built-in component, a smartphone, a personal computer, and the like can be cited, and these devices include an amplifying means. In some cases.

[Amplification means]
The amplifying means is means for amplifying the sound signal reproduced by the sound reproducing means, and the sound signal is amplified by the amplifying means to become audible sound. The acoustic signal amplified by the amplification means is output to the living body part close-contact vibration device. An example of the amplifying means is an amplifier. The amplification means is preferably capable of outputting 10 W or more, preferably 15 W or more, for example.

[sound source]
The sound source (acoustic data) is preferably acoustic data including frequency components with a frequency of 20 Hz to 25 kHz, and more preferably includes frequency components in the range of 200 Hz to 18 kHz. This sound source is supplied from the outside by, for example, a method such as streaming, and is stored in a storage area of a sound reproducing means such as a storage medium such as a CD or a personal computer or a smartphone. As a type of the sound source, music of various genres such as classical music, enka, jazz, rock and the like can be selected as appropriate, and among them, classical music with a wide sound range is preferable.

  The sound source of the present invention may be a sound source artificially formed for treatment. Such an artificial sound source preferably includes a frequency component in the range of 20 to 100 Hz as the low frequency region and a frequency component in the range of 1 to 5 kHz as the high frequency region.

  The biocontact acoustic vibration system provided with the above-described biocontact acoustic vibration device of the present invention will be described more specifically with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a living body contact type acoustic vibration system of the present invention. As shown in FIG. 1, the living body contact type acoustic vibration system 1 includes a living body contact type acoustic vibration device 10, a sound reproducing unit 20, and an amplification unit 30, which are features of the present invention. The sound reproducing means 20 includes a storage area 40 inside, and is configured so that a sound source can be stored in the storage area 40. The sound reproducing means 20 and the amplifying means 30 are electrically connected by a transmission line 50, and the amplifying means 30 and the vibration device 10 are electrically connected by a transmission line 60. The transmission paths 50 and 60 may be wired or may be wireless.

  The vibration device 10 is tightly fixed to the affected part of the wearer, and applies (propagates) vibration based on the acoustic signal to the affected part. As shown in FIG. 2, the vibration device 10 includes a vibration generating unit 100 that generates vibration based on an acoustic signal, and a fixing unit 200 that closely fixes the vibration generating unit to a wearer's living body part. .

  The vibration generating unit 100 includes an input unit 101 to which an externally supplied acoustic signal is input, and a vibration member 102 that converts the acoustic signal input through the input unit 101 into vibration. The part 101 and the vibration member 102 are connected by a transmission path 103.

  The vibration member 102 is a rectangular member, and a plurality (for example, six) of the vibration generating means 100 are arranged in parallel so that the short side thereof is in the long side direction of the vibration generating means 100. By arranging a plurality of vibrating members 102 in parallel, the vibration generating means 100 can be easily bent in the long side direction (parallel direction), and the adhesion can be further improved.

  Moreover, the vibration generating means 100 is fixed to the surface of the fixing means 200, and the vibration generating means 100 is closely fixed to the wearer's living body part. The fixing means 200 is formed in, for example, a rectangular shape (strip shape) that is long in one direction, and attachment / detachment portions 201 and 202 such as hook-and-loop fasteners are provided at end portions in the long side direction.

  In addition, the aspect of the vibration member 102 is not limited to this, For example, it is good also as an aspect as shown in FIG. For example, as shown in FIG. 3A, one rectangular vibration member 102 may be disposed in the vibration generating means 100A. Further, as shown in FIG. 3B, a plurality of (for example, four) circular vibration members 102A may be arranged on the vibration generating means 100B. Further, as shown in FIG. 3C, one circular vibration member 102A may be disposed in the vibration generating means 100C.

  In the vibration generating means 100 having such a configuration, the vibration generating means 100 is fixed by the fixing means 200 so as to be in close contact with the wearer's living body part (affected part such as an arm). An acoustic signal is input to the vibration generating unit 100 from the outside via the input unit 101. The acoustic signals input to the vibration generating means 100 are respectively input to the vibration member 102 via the transmission path 103, and the vibration member 102 converts the acoustic signal into vibration. Thereby, the vibration based on an acoustic signal is provided to a wearer. Here, by closely fixing the vibration generating means 100 to the wearer's living body part, vibration can be directly and intensively applied to the living body part, and the affected part can be effectively treated. . In addition, since the vibration generated by the acoustic signal is audible vibration, the wearer can receive vibration (massage) while listening to the sound, and can treat the affected area in a relaxed state. Thus, an unprecedented therapeutic effect can be obtained.

  In the vibration device 10 according to the above-described embodiment, one vibration generating unit 100 is disposed. However, the present invention is not limited to this. For example, a plurality of vibration generating units 100 may be disposed. For example, as illustrated in FIG. 4, the vibration device 10A includes a plurality of vibration generation means 100A and a fixing means 200A. For example, in the vibration device 10A, a plurality of vibration generating means 100A are arranged in a line along the longitudinal direction of the fixing means 200A.

  A plurality of vibration generating means can be arranged in a matrix (matrix). For example, as shown in FIG. 5, the vibration device 10B includes a vibration generating unit 100B and a fixing unit 200B. A plurality (for example, 3 × 3) of vibration generating means 100B are arranged in a matrix on the surface of the fixing means 200B. The vibration device 10B is applied to a relatively wide range of affected areas such as the waist.

  Further, a dynamic speaker as shown in FIG. 6 can be used as the vibration member. The vibration member 10 </ b> C is a cylindrical member. For example, when a current flows through the voice coil 302 wound around the bobbin (coil base) 301, the vibration unit vibrates due to the Lorentz force. When applied to the present invention, the vibrating body 306 in contact with the tip of the vibrating portion and the loose portion can be transmitted as an acoustic wave to the affected area. Reference numeral 300 represents an attachment substrate for attachment to the vibration generating means or the fixing means.

[Test Example 5]
An acoustic wave was applied to an uncomfortable part of a person who had an uncomfortable state of gums. The application conditions are the same as in Test Example 1. As a result, the feeling of the left gum was completely cured, and the right gum was a little more uncomfortable. The acoustic wave was applied once a day for 2 weeks.

The influence on the effect by the difference of the sound source was examined.
We tested what kind of music was effective as a sound source. As a result, Mozart's “Aine Kleine Hana Tom Sieg”, “Symphony No. 1”, “Divertiment No. 17”, etc. showed remarkable effects in classical music. It is also effective in current pop music, and better results were obtained with more jazz instruments than quartets. Rock was effective in approximate songs. As described above, it has been found that any sound source that produces sound over the entire region is effective as a sound source for acoustic wave vibration.

  Furthermore, as a result of performing frequency analysis of highly effective music and measuring the frequency distribution, it has a frequency component in the range of 200 Hz to 1 kHz and a frequency component in the range of 9 to 18 kHz as the frequency range. The result is that the sound source is more effective. Similarly, a result that a sound source having a frequency component of 100 Hz or less and a frequency component of 1 to 5 kHz is more effective was obtained.

  Since the living body contact type acoustic vibration device of the present invention can be tightly fixed to the affected area of the wearer, for example, by applying vibration locally and intensively to the affected area of the wearer, Treatment can be performed, and for example, new business development such as medical device sales business is possible.
