Description

Potential Therapy Device {ELECTRIC POTENTIAL TREATMENT DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a potential therapy apparatus for applying a high voltage to a human body and forming an electric field around the human body to perform treatment. In particular, even when a wall or an electric device is located near the human body, an appropriate therapeutic effect can be obtained. It relates to an electric potential therapy device.

The dislocation treatment device applies a high voltage to an insulated human body and performs treatment by using a biological stimulus effect by an electric field formed around the human body. In such a potential treatment apparatus, it is known that the electric field strength is controlled so that a small induced current flows to each part of the trunk of the human body (see Patent Document 1, for example). The potential treatment apparatus includes a main electrode, a counter electrode, and an induction current control means, and the induction current control means adjusts (varies) the distance between the counter electrode and the body surface of the human body. In this way, the electric field on the surface of the trunk is controlled so that a small amount of induction current flows to each of the parts constituting the trunk of the human body, so that potential dislocation treatment according to individual differences can be effectively performed.

In addition, an electric potential treatment apparatus is known in which the electric field strength around the human body is increased to increase the therapeutic effect (see Patent Document 2, for example). This electric potential treatment device experiences a contact impedance by applying high voltage simultaneously from the electric chair (electrode) which embeds and embedded an electric conduction conductor (electrode), and the electric conduction stand (electrode) of a leg part. In addition, the voltage applied to the human body and the electric field strength around the human body are increased to increase the treatment effect.

By the way, if an object close to the earth (earth) potential, such as a wall or an electric device, is located in the vicinity (periphery) of the human body undergoing dislocation treatment, an appropriate therapeutic effect may not be obtained. That is, the field strength increases near the wall and the like, and the electric field strength formed around the human body is changed (scattered) according to the human body part, so that a predetermined (adequate) therapeutic effect may not be obtained (Fig. 5 (c). ) Reference]. In addition, since the remote controller or the drive mechanism is operated and driven at a low voltage (for example, 12 V), it is close to the earth potential, and in that case, the electric field is similarly affected, and the remote controller or the drive mechanism is placed near the human body. It was not desirable to install.

On the other hand, in the potential treatment apparatus described in Patent Documents 1 and 2 described above, the electric field strength may be controlled or the electric field strength around the human body may be increased, but the electric field formed when a wall or the like is located near the human body. There is no change in what is affected. For this reason, even if the electric field strength is controlled or the electric field strength is increased, a predetermined therapeutic effect may not be obtained.

Therefore, an object of the present invention is to provide an electric potential treatment apparatus which can suppress the influence of electric walls by surrounding walls, electric devices, and the like, and exhibit an appropriate and stable therapeutic effect.

In order to achieve the above object, the present invention is provided with a potential treatment device having one or a plurality of main electrodes, a high voltage generator for applying a high voltage to the main electrode, and performing treatment at a high potential of the human body disposed in the potential therapy device. In the potential treatment apparatus, a protective electrode is provided along the isopotential surface of the electric field formed around the human body by a high voltage applied to the main electrode, and has a potential having the same electric potential as that at the equipotential surface. .

In addition, the protection electrode is provided in the back side or the side surface of a human body.

According to the present invention, since the protective electrodes having the same potential are provided along the equipotential surface of the electric field, the influence of the electric field formed around the human body is suppressed even if the wall or the electric equipment is located near the human body. That is, the electric field located between the protective electrode and the wall is greatly influenced (dissipated) by the wall or the like, but the electric field located between the protective electrode and the human body, that is, the electric field formed around the human body, is protected. Since it is protected (not scattered) by the electrode, the influence by the wall or the like is suppressed. As a result, even if a wall or an electric device is located in the vicinity of the human body, the influence of the electric field formed around the human body is suppressed, so that an appropriate and stable predetermined treatment effect can be exhibited and maintained.

Further, by providing the protective electrode on the back side of the human body, it becomes possible to provide a drive mechanism or the like for driving the main electrode located above the head of the human body on the back side of the chair back. That is, by providing a drive mechanism or the like outside of the protective electrode (opposite to the human body), an electric field is not affected by the drive mechanism or the like, and an appropriate and stable treatment effect is obtained. Further, by providing the protective electrode on the side of the human body, an appropriate and stable treatment effect can be obtained even if the remote controller or the like is provided on the side of the human body that is easy to operate. That is, by providing a protective electrode between the side of the human body and the remote controller, the influence of the electric field by the remote controller or the like is suppressed, and an appropriate and stable treatment effect is obtained.

Is connected to.

Reference numeral 24 denotes a drive arm (drive mechanism) for driving the head cover 22, and the drive arm 24 is provided on the upper rear side of the chair back 21b of the chair 21. That is, the headrest 21c formed to cover the head from the shoulder of the subject C is provided on the upper side of the chair back 21b, and the driving arm protrudes upward from the back side of the headrest 21c. 24) is installed. Moreover, the side wall 21d which covers the lower part of the torso side of the to-be-treated person C is provided in both (left and right) of the seat part 21a, and the outside (seat part 21a) of one side wall 21d is provided. Remote control 25 (remote controller) is provided. In addition, an insulating leg (not shown) is provided on the lower surface of the side wall 21d or the seat portion 21a to insulate it from the floor.

Then, as shown in FIG. 3, the first protective electrode 7 and the second protective electrode 8 are embedded in the head rest 21c and the side wall 21d. The first protective electrode 7 and the second protective electrode 8 include a seat main electrode 4 and a head main electrode in which a to-be-treated subject C has a standard posture and sits on a chair 21 in a standard posture. When high voltage is applied to (5), it is provided so that the predetermined equipotential surface of the electric field formed around the to-be-treated person C may be followed. Further, the potentials of the first protective electrode 7 and the second protective electrode 8 are set so as to be the potential on the equipotential surface and the coin phase. Specifically, the first protective electrode 7 and the second protective electrode 8 are highly flexible conductive sheets in which mesh-shaped copper wires are incorporated into the resin, and the first protective electrode 7 is the subject to be treated. It is formed (installed) so that it may follow the equipotential surface of the electric field formed around the back surface from the shoulder part of (C) to the head part. The second protective electrode 8 is formed (installed) so as to follow an equipotential surface of an electric field formed around the lower body side (from the hip to the knee) of the subject C, and is supported by the chair 21. In the state where the therapist C sits, it is provided so that the side surface from the hip of the to-be-treated subject C to the knee may be covered. The first protective electrode 7 and the second protective electrode 8 are connected to the voltage output terminal of the high voltage generator 3, so that the potential at each equipotential surface and the voltage at the coincidence are applied.

The high voltage generator 3 shown in FIG. 4 described later includes a power cord for a commercial power supply (not shown), a boost transformer 31 (high voltage transformer) for boosting the voltage to 7,000 to 9,000 V, and a voltage for outputting the voltage. A voltage output terminal is provided. Then, the voltage generated by the boost transformer 31 (high voltage) is passed through the voltage output terminal to the seat main electrode 4, the head main electrode 5, the first protective electrode 7, and the second protective electrode 8. ) Is applied.

The second protective electrode 8 is output to the second protective electrode 8 via the third safety resistor Z3, and is output to the seat main electrode 4 via the fourth safety resistor Z4. Further, in order to suppress the potential of the first protective electrode 7 and the second protective electrode 8 from being affected by the wall or the like, that is, the potential of the first protective electrode 7 and the second protective electrode 8 is In order to be dependent on the potential of the high-potential treated C, the impedances of the second safety resistor Z2 and the third safety resistor Z3 are the first safety resistor Z1 and the fourth safety resistor. It is set lower than Z4). The remote control 25 remotely operates the start, stop and the like of the high voltage generator 3.

Next, the operation and effect of the above-mentioned electric potential treatment device 1 will be described.

First, the patient C is seated on the chair 21, and the high voltage generator 3 is operated. As a result, a high voltage is applied to the seat main electrode 4 and the head main electrode 5, the subject C becomes high in potential, and an electric field is formed around the subject C. The equipotential surface of this electric field is formed around the subject (C). For example, in the upper part (site | part from a shoulder part to a head part) of the to-be-processed person C which is in contact with the head rest 21c, as shown to FIG. Around the ring, equipotential surfaces P1 to Pn are formed. That is, assuming that the subject C is insulated to 1,000 V, from the subject C to the outside, the equipotential surface P1 of 900 V, the equipotential surface P2 of 800 V, and the equipotential surface P3 of 700 V are shown. In turn, the equipotential surfaces of low potentials are formed. In addition, the equipotential surfaces P1 to Pn have a lower potential (as far from the subject C outward) as the potential of the equipotential surfaces decreases, and the distance between the equipotential surfaces increases, and the electric field strength decreases.

By the way, as mentioned above, the 1st protective electrode 7 and the 2nd protective electrode 8 are provided so that the predetermined equipotential surface of the electric field formed around the to-be-treated person C may be followed, and the 1st The potentials of the protective electrode 7 and the second protective electrode 8 are set so as to be the potential at the equipotential surface and coincidence. For example, as shown in Fig. 5A, the first protective electrode 7 is provided in the head rest 21c so as to follow the equipotential surface P2, and the high voltage generator is set such that its potential is 800V. A voltage is applied from (3). That is, the equipotential surface P2 and the first protective electrode 7 are in a state of overlapping (matching) at the shape (surface) and the potential.

In such a state, for example, if the wall W close to the ground potential is located near the subject C (in this case, the head rest 21c), the equipotential surface P1 is formed by the wall W. FIG. Pn) changes (disperses). That is, as shown in Fig. 5 (b), the equipotential surfaces P3 to Pn located between the wall W having the potential of approximately 0V and the first protective electrode 7 are crushed and the gap is It becomes narrower and the electric field strength increases. On the other hand, the equipotential surfaces P1 to P2 positioned between the subject C and the first protective electrode 7 are protected (not scattered) by the first protective electrode 7, and the electric field strength is It does not change. That is, the first protective electrode 7 is formed (installed) along the equipotential surface P2 and is set to the equipotential surface P2 and the coin phase, and the equipotential surface by the first protective electrode 7 is provided. Since the (physical surface) is not changed by the wall W, the first protective electrode 7 protects the equipotential surfaces P1 to P2. As a result, even if the wall W is located in the vicinity, the equipotential surfaces P1 to P2 around the vicinity of the subject C do not change (influence), and the wall W and the like are not in the vicinity. The predetermined therapeutic effect when not located is exhibited and maintained appropriately and stably.

On the other hand, if the 1st protective electrode 7 is not provided, as shown in FIG.5 (c), all equipotential surfaces P1-Pn change with the wall W. As shown in FIG. That is, all the equipotential surfaces P1 to Pn are crushed, the gap is narrowed, and the electric field strength is increased. As a result, the electric field strength formed around the to-be-treated person C changes according to the part of the human body (dispersed) so that a predetermined (adequate) therapeutic effect is not obtained.

As described above, according to the present potential treatment apparatus 1, even if the wall W and the like are located in the vicinity, the electric field around the subject C does not change, so that an appropriate and stable treatment effect is obtained. Lose. In other words, the predetermined therapeutic effect is stably obtained regardless of whether or not there is a wall W or the like in the periphery. In addition, since the driving arm 24 is provided on the back side of the head rest 21c, i.e., on the outer side of the first protective electrode 7 (opposite to the subject C), the driving arm 24 is mounted. Even in the case where the potential is close to the potential, similar to the case of the wall W described above, the electric field around the subject C does not change, so that an appropriate and stable therapeutic effect is obtained. Similarly, since the remote control 25 is provided on the outer side of the side wall 21d, that is, on the outer side of the second protective electrode 8 (opposite to the subject C), the remote control 25 The electric field around the subject C does not change, so that an appropriate and stable therapeutic effect is obtained. In addition, since the first protective electrode 7 is provided in the head rest 21c, and the second protective electrode 8 is provided in the side wall 21d, the head rest (without affecting the treatment effect) is provided. It is possible to provide the driving arm 24 or the like on the rear side of 21c) or to install the remote control 25 or the like on the outer side of the side wall 21d. That is, the addition of the function (accessory) of the dislocation treatment device 1 and the degree of freedom in design can be increased, and the frame of the chair 21 itself can be made of a metal material, which can be advantageously advantageous in strength.

By the way, in this embodiment, for example, the potential of the 1st protective electrode 7 so that the electric potential of the 1st protective electrode 7 and the 2nd protective electrode 8 may become the electric potential in the equipotential surface and a coincidence. Although a voltage is applied from the high voltage generator 3 so that is 800 V (potential of the equipotential surface P2), the same effect is obtained even if the potential and the coincidence on the equipotential surface are not coincident. That is, if the potential of the first protective electrode 7 and the second protective electrode 8 is equal to the potential on the equipotential surface, the subject C and the first protective electrode 7 and the second protective electrode The equipotential plane located between the electrode 8 and the electric field does not change significantly, so that a predetermined therapeutic effect is obtained. For example, in the case of the first protective electrode 7 described above, even if the potential is 700 V, the equipotential surfaces P1 to P2 are protected (not greatly changed), thereby obtaining a predetermined therapeutic effect. On the other hand, as described above, since the first protective electrode 7 and the second protective electrode 8 are installed (formed) based on the standard posture of the standard subject C, the actual subject There may be a case where the equipotential surface of the electric field formed around (C) does not coincide completely. That is, even if the potentials of the first protective electrode 7 and the second protective electrode 8 are set at the potential on the standard equipotential surface and the coin, at least in part, the potentials do not coincide (the equipotential surface and the first The protective electrode 7 and the second protective electrode 8 do not coincide with each other. However, even in such a case, there is an action (effect) of protecting the equipotential surface located between the subject C, the first protective electrode 7, and the second protective electrode 8, and the subject C The electric field around the periphery does not change significantly, and a predetermined therapeutic effect is obtained. As described above, the shape (installation state) and the potential of the first protective electrode 7 and the second protective electrode 8 are most preferably identical to the shape of the equipotential surface and the potential, but the same degree is the same. An action is obtained. Therefore, the shape and potential of the first protective electrode 7 and the second protective electrode 8 depend on the standard body type, the site of installation, the number of installation, the degree of effect, and the like. You decide.

In the present embodiment, the potential therapy device 2 is a chair type potential therapy device 1 or the potential therapy device is a bed type potential therapy device. The first protective electrode 7 and the second protective electrode as described above are used. It goes without saying that (8) may be provided.

As described above, the potential treatment apparatus according to the present invention is very useful as an apparatus for obtaining an appropriate and stable therapeutic effect even when a wall, an electric apparatus, or the like is located in the vicinity of the human body of the subject.
