Description

  The present invention relates to a biobattery treatment device, and more particularly to a biobattery treatment device that is used in contact with a living body such as skin and that treats a target site by energization stimulation to a subcutaneous tissue of weak DC electromotive force.

  In recent years, an increasing number of patients suffer from chronic stiff shoulders and low back pain, and so far, many poultices, hot tubs, metal particles, magnetic treatment devices, low frequency treatment devices, etc. have been marketed as home treatment devices. These therapeutic tools promote the circulation of the affected area according to various principles, and have the effect of purifying locally accumulated waste.

  As a treatment tool based on a principle different from the above-described general treatment tool, a biobattery treatment tool that heals muscle and nerve fatigue by energization stimulation has been proposed (for example, see Patent Documents 1 to 4). The biobattery treatment device is a superior treatment device that forms a biobattery when it comes into contact with the skin and gives a direct current, and has a therapeutic effect equivalent to or higher than that of the above-mentioned home treatment device. Has been demonstrated.

  A conventional biological battery treatment tool is a biological battery that uses an N-type semiconductor such as Zn for a negative electrode and a noble metal for a positive electrode (see, for example, Patent Documents 5 to 10). FIG. 4 shows a typical shape of such a conventional biological battery treatment device. This treatment instrument is composed of a pedestal 1, an N-type semiconductor 2 and a support 3. The pedestal 1 is made of a synthetic resin with gold plating, and the gold-plated portion acts as a positive electrode of the battery. On the other hand, the N-type semiconductor 2 is held upright on the base 1 and functions as a negative electrode of the battery. This biological battery treatment device is a treatment device that provides a therapeutic effect by applying a weak current stimulus to a living body by attaching a pedestal 1 acting as a positive electrode and a semiconductor 2 acting as a negative electrode to the skin 4.

By the way, the weak current stimulation includes two kinds of weak current stimulation, that is, polymodal stimulation and mitochondrial activity.
The polymodal stimulation is preferably a biobattery treatment device capable of passing a weak current capable of stimulating a polymodal receptor that senses a noxious stimulus (stress).
On the other hand, the mitochondrial activity is preferably a biobattery treatment device capable of passing a very weak current approximate to the value of the bioelectric current flowing through nerves and the body.
Thus, even if it was a biological battery treatment tool, there was a considerable difference in the current value required depending on its purpose. However, as described above, since the positive electrode is specified as a noble metal and the negative electrode is specified as an N-type semiconductor such as Zn, the conventional biological battery treatment device has a limit in selection between the positive electrode and the negative electrode, and the biological battery treatment is limited. It was a bottleneck in designing the tool.

JP-A-8-173554 JP 11-123245 A JP 2000-84093 A JP 2000-126308 A JP 2000-237322 A JP 2000-237323 A JP 2000-237324 A JP 2007-130145 A JP 2009-050360 A JP 2012-205884 A

  Therefore, the present inventor considered using a metal with a passive film instead of the noble metal as the positive electrode. We have found that there is a metal with a noble potential. As a result, it was found that various metals including noble metals can be selected as the metal constituting the negative electrode, and various biological battery treatment devices can be designed according to the purpose.

As a result of further research, there is a biobattery treatment device using a metal with a passive film formed on the positive electrode, particularly a metal selected from titanium, a titanium alloy, and a titanium compound, and a noble metal, particularly silver and copper, on the negative electrode. It was found that a very weak current effective for mitochondrial activity can be passed.
Also effective for polymodal stimulation using a metal with a passive film on the positive electrode, especially a metal selected from titanium, titanium alloys, and titanium compounds, and a metal with a large potential difference from the positive electrode, especially zinc, on the negative electrode. It was found that a very weak current can be passed.

This invention is made | formed based on said knowledge, and is equipped with the following structures.
The biological battery treatment device according to the present invention is an electric circuit in which a positive electrode (anode) and a negative electrode (cathode) are electrically connected, and a weak current is passed through the living body by bringing the positive electrode and the negative electrode into contact with the living body. The positive electrode is a metal having a passive film formed thereon, and the ionization tendency is more precious than the metal constituting the negative electrode by forming the passive film.

The “biological battery treatment device” in the present invention is used in a broad sense. That is, the biological battery treatment device is also referred to as a skin treatment device (see, for example, JP-A-2002-37322, JP-A-2002-37323, JP-A-2002-37324, JP-A-2009-050360). Are also included in the present invention, but the present invention is not limited to these names. For example, a hair combing tool to which the present invention is applied (refer to, for example, Japanese Patent Laid-Open No. 2000-236932 for the configuration of the “hair combing tool” itself, for example, see Japanese Patent Laid-Open No. 2002-236946 for the configuration of the “beauty tool” itself). Electronic toothbrushes (for example, see Japanese Patent Application Laid-Open No. 2002-36948 for the configuration of the “electronic toothbrush” itself), devices used for transdermal administration (see, for example, Japanese Patent Application Laid-Open No. 2003-169853 for the structure of such a device itself), For the configuration of a sonic facial device (for example, see Japanese Patent Application Laid-Open No. 2012-205884 for the configuration of the “ultrasonic facial device” itself), for example, for the configuration of a nasal cavity expansion member (for example, “nasal cavity expansion member”) Reference) is also included in the technical scope of the present invention as long as it includes the components of the present invention.
In short, it is a device that forms an electric circuit that allows a weak current to flow through a living body by bringing the positive electrode and the negative electrode into contact with the living body, in which the positive electrode is a metal with a passive film and the negative electrode forms the electric circuit. In the present invention, the positive electrode is a metal having a passive film, and by forming a passive film, if the metal has a preferential property of ionization than the metal constituting the negative electrode, the “biological battery” of the present invention It is included in “therapeutic device”.

"Electrically connecting" the positive electrode and the negative electrode is not limited to the case where the positive electrode and the negative electrode are in direct physical contact, but indirectly through other conductive members or conductive materials. Including when connected to Specific modes in which “the positive electrode and the negative electrode are electrically connected” are various as can be understood from the descriptions of Patent Documents 1 to 10 and the like described above. Here, although not specifically illustrated, it is naturally not limited to Patent Documents 1 to 10 and includes various known forms.
The “living body” indicates not only a human body but also a living organism in general.
“Contacting the positive electrode and the negative electrode to the living body” is intended to cause a weak current to flow through the living body by bringing the positive electrode and the negative electrode into contact with each other. Therefore, the positive electrode and the negative electrode are separated from each other by a distance that allows a weak current to flow through the living body. Means contact. The contact location is the location of the electrolyte through which current flows, such as the skin.

“Weak current” means an electric current having a strength sufficient to achieve the purpose of the biological battery treatment device. For the purpose of mitochondrial activity, depending on the depth from the epidermis, a weak current of about 0.01 μA to 1200 μA, preferably about 0.05 μA to 800 μA, particularly preferably about 0.1 μA to 600 μA at a voltage of about 30 to 100 mV. Is preferred. When polymodal stimulation is intended, depending on the depth from the epidermis, a weak current of about 0.01 μA to 3000 μA, preferably about 10 μA to 1500 μA, particularly preferably 50 μA to 1200 μA is preferable at a voltage of about 200 mv to 1300 mv. .
“Precious metal” means scientifically gold (Au), silver (Ag), platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru), osmium (Os). Practically, gold, silver, platinum, and copper are mentioned practically. In particular, silver or copper is suitable because it is widely known that even if ionized, it does not adversely affect the living body. The “noble metal” of the present invention includes an alloy containing a noble metal as a main component.

In the present invention, the term “metal” means a metal as a material that can constitute a positive electrode or a negative electrode, and is used in a broad sense that includes alloys, metal oxides, and the like, unless there is a contradiction or overlap in description. It is done.
The “metal having a passive film” refers to a metal having a passive film formed on at least the surface in contact with the living body. Examples of the metal capable of forming a passive film include aluminum, nickel, titanium, chromium, molybdenum, alloys and compounds containing these metals as main components, and stainless steel. Passive coating is generally formed when metal comes into contact with the environment and grows and stabilizes over time, but it can be treated by anodization, oxidation, electrolysis using dilute sulfuric acid, etc. Can also be formed. Each method of forming a passive film is widely known to those skilled in the art, and in the present invention, the passivation process can make the ionization tendency “noble” more than the metals (including noble metals) used as the negative electrode. The treatment method is not limited as long as it is preferably a passivation treatment capable of making the ionization tendency smaller than that of hydrogen.

"The positive electrode is a metal with a passive film, and by forming a passive film, the ionization tendency is more precious than the negative electrode" means that the positive electrode metal originally has an ionization tendency. Utilizing the change to the “noble” property by forming a passive film, the combination of the metal on which this passive film is formed and other metals (including noble metals) In the lower part (generally in the atmosphere), the combination is selected such that the metal on which the passive film is formed becomes the positive electrode and the other metals (including noble metals) become the negative electrode. For example, a combination of a metal selected from titanium, a titanium alloy, and a titanium compound formed with a passive film, and silver, a metal selected from titanium, a titanium alloy, and a titanium compound formed with a passive film, and copper And a combination of a metal selected from titanium, a titanium alloy, and a titanium compound formed with a passive film, and zinc. In this case, any alteration such as oxidation of the surface of zinc constituting the negative electrode may be used.
The first described combination and the second described combination are particularly suitable combinations for mitochondrial activity, and the third described combination is a particularly suitable combination for polymodal stimulation.
As the titanium alloy, any of α alloy, β alloy, and α-β alloy can be applied. For example, Ti-3Al-2.5V, Ti-6Al-4V, Ti-6Al -7Nb and the like. Examples of titanium compounds include Ti carbides such as TiC, Ti nitrides such as TiN, Ti carbonitrides such as TiCN, Ti carbonates such as TiCO, Ti carbonitride oxides such as TiCNO, and the like. However, the exemplified titanium alloys and titanium compounds are only examples, and the titanium alloys and titanium compounds of the present invention are not limited to these exemplified titanium alloys and titanium compounds.

  According to the present invention, by using a metal in which a passive film is formed for the positive electrode, it is possible to appropriately select a negative electrode including a noble metal, and as a result, a biobattery treatment device suitable for polymodal stimulation, A biological battery treatment device effective for mitochondrial activity can be appropriately designed and manufactured.

The biological battery treatment device suitable for mitochondrial activity obtained by the present invention (a biological battery treatment device using a noble metal for the negative electrode) exhibits the following specific effects.
That is, there is a theory called “micro current therapy” as a method for promoting activation at the cellular level of the body, which has recently been approved as a treatment method by the US FDA. In order to activate the cell itself, ATP (Adenosine Triphosphate), the cell's only energy source, is produced by mitochondria in the cell, but this theory applies a weak current to the cell. This is a therapy that activates ATP production by mitochondria. That is, in the normal state according to the concentration difference between the inside and outside of the cell such as sodium ion and potassium ion, the inside of the cell membrane is at a negative potential of minus 40 mV to 50 mV with respect to the potential outside the cell membrane. However, when cells are activated, the potential in the cell membrane gradually increases in the positive direction, and mitochondria begin to produce ATP at about minus 10 mV to 20 mV, which has increased by about 30 mV. It is said that when a cell is actively active by consuming ATP, which is an energy source, the potential in the cell membrane reaches plus 70 mV. The theory that the cell is activated by applying a potential difference of 120 mV from minus 40 mV to 50 mV while the cell is resting to plus 70 mV when the cell is active from the outside is the micro current therapy.
However, in a conventional biobattery treatment device using an N-type semiconductor (zinc) as a negative electrode and a noble metal (gold) as a positive electrode, a current of about 650 μA to 1200 μA flows at about 1000 mV. The value is too high to be a current value suitable for weak current therapy.
In addition, although the weak current treatment device itself is known, the weak current treatment device currently used is to pass a weak current to the affected part by holding both the positive electrode and the negative electrode in the hand. It is a large-scale device that costs millions of yen due to the current drop. Moreover, only one current line flows between the positive and negative electrodes as an electrical characteristic. Furthermore, it is performed while holding the electrode in hand and sliding the skin. However, since it is based on human power, the treatment time is only about 30 minutes, and the treatment cannot be performed for a necessary and sufficient time.
In contrast, the biological battery treatment device of the present invention is basically inexpensive and disposable, and can be activated for a long time by applying for a long time. Is effective. For example, the cause of wrinkles on the face is wrinkles with loss of elasticity due to aging of fibroblasts, but according to the present invention, wrinkles can be prevented and anti-ageed by activation of fibroblasts. In addition, early cell formation in damage such as fractures and trauma is possible. Such a weak electromotive force is a remarkable effect that cannot be achieved by a combination of a conventional noble metal positive electrode and a base metal negative electrode.

Furthermore, since the biological battery treatment device suitable for mitochondrial activity can use a noble metal for the negative electrode, the problem of metal allergy due to the ionized metal can be solved.
That is, according to the Ministry of Health, Labor and Welfare documents, all metals may be allergic, but so-called noble metals (gold, silver, copper, etc.) have a low risk of allergies. As it can be seen from the fact that it is used in the field, it is widely known as a good metal with a very low possibility of allergies.
In order to eliminate the problem of metal allergies, it is necessary to use a noble metal having a lower ionization tendency than the noble metal for the positive electrode, but in this case, it is necessary to use a noble metal for both the positive electrode and the negative electrode, which is costly. There is a problem of getting higher.
In the present invention, a metal having a passive film is used for the positive electrode, and a noble metal that is unlikely to cause metal allergy is used for the negative electrode. Therefore, the problem of metal allergy can be solved and reduced without increasing the manufacturing cost. it can.

Moreover, the biological battery treatment tool suitable for polymodal stimulation obtained by the present invention exhibits the following specific effects.
In other words, the conventional biobattery treatment tool requires the use of noble metals. In the present invention, the metal on which the passive film is formed functions as a positive electrode instead of the noble metal, so that it is not necessary to use the noble metal. As a result, the manufacturing cost can be reduced as compared with the prior art. In particular, in the biobattery treatment device using titanium as the positive electrode and zinc as the negative electrode, a current suitable for polymodal stimulation flows stably, so that the effect of the biobattery treatment device suitable for polymodal stimulation is effectively exhibited. The

FIG. 1 is a plan view showing an embodiment of a biological battery treatment device. 2 is a cross-sectional view of the biological battery treatment tool of FIG. FIG. 3 is a plan view of an insulating layer of the biological battery treatment device of FIG. FIG. 4 is a cross-sectional view showing an example of a conventional biological battery treatment tool.

Hereinafter, an example of an embodiment of the present invention will be described with reference to FIGS.
The present invention is not limited to this embodiment. The present invention includes a biobattery treatment device in which the constituent elements of the present invention specifically described above are arbitrarily combined.

  The biological battery treatment device according to the first embodiment of the present invention is a treatment device suitable for mitochondrial activity, and has a disk-shaped insulating layer on the surface of the disk-shaped base 10 (the surface side in FIG. 1 and the upper side in FIG. 2). 20 and a negative electrode 30 is provided on the surface of the insulating layer 20. The insulating layer 20 is formed concentrically with the pedestal 10 and has a smaller diameter than the pedestal 10. The negative electrode 30 is composed of a plurality of negative electrode pieces 30 a, and is formed concentrically with the insulating layer 20 as a whole and has a smaller diameter than the insulating layer 20.

The pedestal 10 is a disc made of titanium, and a passive film is formed on an outer peripheral region 10 a that is not covered with at least the insulating layer 20 on the surface (the surface side in FIG. 1, the upper side in FIG. 2). And the area | region which formed this passive state film | membrane acts as a positive electrode. The method for forming a passive film is not particularly limited, and conventionally known methods for forming a passive film can be appropriately applied. As an example, a passive film is formed by immersing a titanium disc body and a copper piece that form a positive electrode in physiological saline and electrically connecting the two.
The insulating layer 20 is made of, for example, urethane resin and is formed by a printing method or the like. As shown in FIGS. 2 and 3, the insulating layer 20 has a plurality of through holes 22. Each through hole 22 is formed in the thickness direction at a location corresponding to the substantially central portion of each negative electrode piece 30a made of noble metal.
The negative electrode 30 is formed, for example, by applying a silver paste on the insulating layer 20 by a printing method or the like. The negative electrode 30 is composed of an innermost disc-shaped negative electrode piece 30a, five divided circumferential negative electrode pieces 30a on the outer periphery thereof, and eight divided circumferential negative electrode pieces 30a on the outer periphery thereof. Has been.

  The innermost negative electrode piece 30a, the five negative electrode pieces 30a on the outer periphery thereof, and the eight negative electrode pieces 30a on the outer side thereof are separated from each other and are insulated via the insulating layer 20. The five negative electrode pieces 30a on the outer periphery of the innermost negative electrode piece 30a have the same shape and dimensions, and are arranged at equal intervals. The insulating layers 20 are insulated from each other. The eight negative electrode pieces 30a outside the five negative electrode pieces have the same shape and size, and are arranged at equal intervals. The insulating layers 20 are insulated from each other. Each of the through holes 22 is filled with the applied silver paste, and as a result, each negative electrode piece 30a constituting the negative electrode 30 and the base 10 constituting the positive electrode are electrically connected.

  The biological battery treatment tool configured as described above is in contact with the living body in a state where the pedestal 10 forming the positive electrode and the negative electrode pieces 30a of the negative electrode 30 are separated from each other by a predetermined distance by bringing the surface side into contact with the living body. As a result, a weak current flows through the living body. This acts as a biological battery treatment tool.

By the way, in the biological battery treatment tool, ions emitted from the negative electrode are directed to the positive electrode, thereby stimulating the living body and exhibiting its effect. Therefore, if a large number of negative electrodes are arranged, ions from a large number of locations can be obtained. The positive effect can be exhibited as a biological battery toward the positive electrode. On the other hand, it is not necessary to increase the number of positive electrodes. Therefore, this type of biological battery treatment device is provided with many negative electrodes.
In this embodiment, since the negative electrode is a noble metal, by applying a noble metal paste as in this embodiment, a large number of negative electrodes of any shape can be easily arranged and formed. On the other hand, the base on which the passive film is formed is titanium that is difficult to process, but can be used as a positive electrode in a disk shape that is punched out of a flat plate, for example.
Therefore, according to this embodiment, there are advantages in manufacturing that a large number of negative electrodes can be easily disposed and formed, and a pedestal having poor processability can be used without complicated processing. By providing a large number of negative electrodes, it is possible to obtain a biobattery treatment device with more excellent therapeutic effects.

  Various pastes for electronics, in which noble metals are processed into fine particles and added to resins, have been developed. Therefore, not only the silver of the embodiment but also other noble metals can form a negative electrode by the same method. Further, the method for forming the negative electrode is not limited to the paste application, and it can be formed by any other conventionally known method. And all the negative electrodes do not need to be a noble metal, and of course, the location which touches a biological body should just be a noble metal.

  In this embodiment, an insulating layer is interposed between the positive electrode and the negative electrode, and this insulating layer is a urethane resin. However, an insulating thermoplastic resin, an insulating acrylic resin, a polyurethane resin, polyvinyl acetate, Vinyl chloride, polyester, polyether, polyacrylonitrile, polystyrene, polyethylene, polypropylene, polyamide, polycarbonate, phenoxy resin, and the like are also possible. Further, as long as it is insulative, it is possible to use other materials as well as the insulating resin.

Next, a biological battery treatment tool according to a second embodiment suitable for polymodal stimulation will be described. The biological battery treatment device according to the second embodiment is the same as the biological battery treatment device according to the first embodiment except that the material of the negative electrode pieces 30a is changed to zinc, and there is no other change. Since the shape and the like are the same as those of the first embodiment shown in FIGS. 1 to 3, the drawings of the second embodiment are omitted.
According to the second embodiment, since no precious metal is used, the manufacturing cost can be suppressed, and a current suitable for polymodal stimulation can be flowed stably.

(Experimental example 1)
An experimental example for confirming that a metal having a passive film is a positive electrode and a noble metal is a negative electrode is related to a biological battery treatment device suitable for mitochondrial activity.
A titanium plate piece and a silver plate piece were immersed in physiological saline, both metal pieces were electrically connected, and the voltage and current were measured. Initially, current flowed from the silver plate piece to the titanium plate piece at a voltage of 130 mV to 160 mV. However, when left for about 24 hours, a current of 0.1 μA to 2 μA flowed from the titanium plate piece to the silver plate piece at a voltage of about 90 to 100 mV, and was almost stable at this value. From this result, it was confirmed that the surface of the titanium plate piece was passivated to act as a positive electrode, and silver was acting as a negative electrode. Moreover, it was confirmed that the voltage and current values were suitable for the above-described weak current therapy.

  When an experiment similar to the above was performed using a titanium plate piece and a copper plate piece, when left for about 24 hours, a current of 4 μA to 5 μA flowed from the titanium plate piece to the copper plate piece at a voltage of about 300 mV. Stable. From this result, it was confirmed that the surface of the titanium plate piece was passivated and acted as a positive electrode, and copper acted as a negative electrode.

(Comparative example)
In the same experimental method as described above, the present inventor also experimented with a combination of titanium and gold having a passive film and a combination of stainless steel and gold having a passive film. In this experiment, gold showed a behavior as a positive electrode, and both titanium and stainless steel on which a passive film was formed by this experimental method showed a behavior as a negative electrode, and could not be a biological battery treatment according to the present invention. . Furthermore, the same experiment was conducted for a combination of stainless steel and silver on which a passive film was formed. However, at least in this experiment, silver showed a behavior as a positive electrode, and stainless steel in which a passive film was formed by this method showed a behavior as a negative electrode, and could not be a biological battery treatment device according to the present invention.
This comparative experiment requires that, in the present invention, “the metal on which the passive film constituting the positive electrode is formed has a higher ionization tendency than the noble metal on which the negative electrode is formed”. This is an experimental example showing that it is not necessary to form a working film. In other words, there are various methods for forming a passive film, and given that the properties of the resulting passive film are not constant, this comparative experiment can be performed, for example, between titanium and gold with a passive film formed. It is clear that the combination, the combination of stainless steel and gold formed with a passive film, and the combination of stainless steel and silver formed with a passive film are not meant to be excluded from the present invention. is there.

(Experimental example 2)
Next, regarding a biological battery treatment device suitable for polymodal stimulation, an experimental example is shown in which it is confirmed that the metal on which the passive film is formed becomes the positive electrode and zinc becomes the negative electrode.
In the same experimental method as described above, the voltage and current of a biological battery treatment device using titanium with a passive film formed on the positive electrode and zinc as the negative electrode were measured. As a result, a current of about 650 μA flows at a voltage of about 900 mV, and this value is almost stable, confirming that this is a biological battery treatment device suitable for polymodal stimulation.

  In addition, for those skilled in the art who have electrochemical knowledge such as ionization tendency of the metal, by understanding the technical idea of the present invention, the metal forming the passive film constituting the positive electrode and the metal constituting the negative electrode are appropriately selected. In combination, it is clear that a biological battery treatment device suitable for mitochondrial activity according to the present invention and a biological battery treatment device suitable for polymodal stimulation can be easily designed and manufactured other than the biological battery treatment device exemplified in the above experimental example. .
