Hereinafter , preferred embodiments of a medical coil will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing the overall configuration of the medical coil, and FIG. 2 is a cross-sectional view of a portion of the medical coil 30 shown in FIG. 1 (A portion in FIG. 1) cut in the thickness direction. The figure is shown.

The medical coil 30 in the present embodiment includes two spiral coils 32a and 32b that are wound in the same direction and spirally wound in a flat shape.
The medical coil 30 has such two spiral coils 32a and 32b arranged so as to overlap in the thickness direction of the medical coil 30, and is formed in a substantially circular shape when viewed in plan.

  Further, in each of the spiral coils 32a and 32b, the inner ends of the spiral are electrically connected, and the outer ends of the spiral are electrically connected. In FIG. 1, a portion 31 where the outer ends of the spiral are connected is shown in a solid color.

  Among the spiral coils, one spiral coil 32a is disposed above the thickness direction of the medical coil 30 (when the thickness direction is the vertical direction), and the other spiral coil 32b is disposed in the thickness direction. Although arrange | positioned below, the fusion | melting conducting wires 34a and 34b which comprise each spiral coil 32a and 32b at this time are arrange | positioned so that the position of the radial direction of the medical coil 30 may correspond. That is, when viewed in cross-section as shown in FIG. 2, the fusion conducting wire 34a of the upper spiral coil 32a and the fusion conducting wire 34b of the lower spiral coil 32b are arranged in a straight line along the thickness direction (vertical direction). It is provided so as not to shift in the radial direction (lateral direction).

In addition, as the fusion | melting conducting wire 34 which comprises each spiral coil 32a, 32b, the circumference | surroundings of the conducting wire 36 (made of metals, such as copper) are coat | covered with insulation coating 37, such as a polyurethane, and also the circumference | surroundings of the insulation coating 37 are fused. What was coat | covered with the coating | cover 39 is employ | adopted.
In the present embodiment, a heat-sealable resin is used as the fusion coating, and specifically, a polyester-based or polyamide-based thermoplastic elastomer is used.

1 and 2 show the case where a round wire (cross section is circular) is used as the fusion-bonding lead.
However, in the medical coil of the present invention, as shown in FIG. 3, a rectangular fused wire 44 may be used. The cross section of the fusion conducting wire 44 that is a flat wire is square.

  The rectangular fused wire 44 has the same configuration as the round wire described above, and the periphery of the square-shaped conducting wire 56 (made of metal such as copper) is covered with an insulating coating 57 such as polyurethane. The insulation coating 57 is covered with a fusion coating 59. In the present embodiment, a heat-sealable resin is used as the fusion coating, and specifically, a polyester-based or polyamide-based thermoplastic elastomer is used.

  Of the spiral coils 42a, 42b using such a rectangular wire 44, one spiral coil 42a is disposed above the thickness direction of the medical coil 30 (when the thickness direction is the vertical direction), and the other The spiral coil 42b is disposed on the lower side in the thickness direction, and at this time, the fusion conducting wires 44a and 44b are disposed so that the positions in the radial direction of the medical coil 30 coincide with each other. That is, the fusion conducting wire 44a of the upper spiral coil 42a and the fusion conducting wire 44b of the lower spiral coil 42b are arranged in a straight line along the thickness direction (vertical direction), and the radial direction (lateral direction). ).

A method for manufacturing the medical coil 30 described above will be described with reference to FIG. In addition,
In the following, a round wire is illustrated as an example of the fusion-bonding wire, but the same method can be used even for a rectangular wire.
First, the linear fusion lead wire 34 is prepared for a predetermined length (a). Next, the center in the length direction of the fusion-bonding wire 34 is sandwiched in a winding jig 47 for winding the fusion-bonding wire 34 (b).

  Here, the winding jig 47 will be described. The winding jig 47 includes two rod-like members 49 and 49 arranged at a predetermined interval from each other, and is provided so as to be rotatable about an intermediate position between the two rod-like members 49 and 49. Yes. That is, the two rod-shaped members 49, 49 are attached to a base 50 that is rotatably provided in a driving means (not shown) such as a motor, or are integrally formed. Rotate and wind the fused conductor 34.

Returning to the description of the manufacturing process of FIG.
After sandwiching the center in the length direction of the fusion conducting wire 34 between the two rod-shaped members 49, 49 of the winding jig 47, the driving means is driven to melt around the two rod-shaped members 49, 49. The lead wire 34 is wound in a spiral shape (c). In this way, by grasping the center of the linear fusion lead 34 and rotating the sandwiched portion horizontally so that the grasped portion becomes the center of the spiral, A coil can be generated.

  In addition, as shown in FIG. 4 (c), in the initial winding state, the welding conductor 34 is not sandwiched between the rod-shaped members 49 and 49, and the winding conductor 34 is not immediately started, but the center of the welding conductor 34 is sandwiched. Start the winding after shifting the height on both sides. The shifting width may be shifted by 0.5 for each of the fusion-bonded wires. In this way, the positions of both sides of the fusion lead wire 34 are shifted by 0.5 pieces of the fusion lead wires in the height (coil thickness) direction, respectively, so that they are wound on both the left and right sides of the center. The fused conducting wire 34 is wound in a state of being in close contact in the vertical direction (thickness direction).

In addition, as shown in (c) and (d), both ends 34a and 34b of the fusion conducting wire 34 are pulled with the same force at the time of winding, and the positions of both ends 34a and 34b are the same at the end of winding. Like that.
In addition, when winding the fusion conducting wire 34 in a spiral shape, in order to fix the wound fusion conducting wire 34, hot air is blown to the winding portion so as to fuse the windings.

  After the winding of the fusion conducting wire 34 is completed, the coverings of both ends 34a, 34b of the fusion conducting wire 34 at the outermost winding end portion of the spiral are peeled, and both ends 34a, 34b are connected by soldering or the like. Thereby, manufacture of the medical coil in this embodiment is completed.

Next, FIG. 5 shows an equivalent circuit of the medical coil, and FIG. 6 illustrates an embodiment of the medical coil.
Medical equivalent circuit of Ryoyo coil 30 can be thought to be two coils 32a which are structurally winding direction as shown in FIG. 5 are opposite, 32b are connected in series.

In this equivalent circuit, one end portion 32ax of the upper coil 32a and the other end portion 32by of the lower coil 32b are connected to each other. Although not shown in FIG. 5, the other end 32ay of the upper coil 32a and the one end 32bx of the lower coil 32b are actually connected.
Such a connection between two coils may be referred to as a differential connection. The differential connection is a connection method in which when a current is passed through such two coils, the magnetic flux generated in each coil is reversed.

  As described above, in the medical coil 30 in which the two coils 32a and 32b whose winding directions are opposite to each other are connected in series, the coil positioned on the upper side of the drawing is hereinafter positioned on the first coil 32a and the lower side for convenience. The coil is referred to as a second coil 32b.

For example, consider the case where the medical coil 30 of the present invention is placed in a place where the magnetic flux density B ₀ exists from the bottom to the top.
Normally, when a coil is placed in a magnetic field, the coil does not operate unless there is a change in the magnetic flux density B ₀ of the magnetic field. However, when a current is applied to the coil from the outside, a force is applied to the coil so as to move in the magnetic field based on the Fleming left-hand rule. In the medical coil of the present invention, since no external current is applied, no force based on Fleming's law is generated.

Further, when the magnetic flux density B ₀ is changed, an induced electromotive force is generated in both the coils 32a and 32b in such a direction as to cancel the change in the magnetic field, based on Faraday's law of electromagnetic induction.
Considering this, it is considered that the action of the medical coil appears in a state where the magnetic field is changing.

For example, as shown in FIG. 6, a weak magnetic field (magnetic flux density B ₀ ) is generated from the human body X, and a hypothesis is established that this magnetic field is constantly changing. This is considered that the muscle current I flows in the human body X, and a magnetic field based on the muscle current I is generated outside the human body X.

Then, the medical coil 30 of the present invention is placed against this changing magnetic field. Then
Magnetic fields that change in the centers of the first coil 32a and the second coil 32b wound in opposite directions pass through the first coil 32a and the second coil 32b, respectively, and counter electromotive force in a direction that cancels the change in the magnetic field. Although it is going to occur, since the first coil 32a and the second coil 32b are connected in series, no current should actually flow.
As described above, even if an electromotive force is to be generated, a current that flows through each coil cancels and does not flow, so there is a possibility that a high energy field is generated inside the coil. And it is thought that the pain of the affected part may be cured by the influence of this energy field.

Thus, it is unclear why the pain and stiffness of the human body are quickly relieved in the medical coil 30 based on Maxwell's classical electromagnetism.
As a theory, it is considered that abnormal electromagnetic waves are output from the affected part of the human body, and this medical coil absorbs abnormal electromagnetic waves.
Yet another theory is that the body current is abnormal in the affected area, and it is thought that the body current is stagnant, but the current that the medical coil is stagnant may flow well. Theories are also being considered.

Next, the clinical results of patients who have used medical coils on a trial basis (those who do not go to the hospital, but live in daily life) are described.
(1) A 74-year-old man. There was a disease in which a runny nose began to flow when I started work on a winter morning. However, when the medical coil was attached to both sides of the nose, the runny nose immediately stopped.
(2) A 72-year-old woman. Although it was bent forward due to back pain, when 3 medical coils were attached to the waist, it became possible to walk upright little by little.
(3) A 75-year-old man. My left leg shined while sleeping. When the medical coil was attached to the most painful part of the affected area, the pain subsided within a few seconds.

(4) A 60-year-old man. My calf on my foot was struck. When the medical coil was applied to the affected area, the pain immediately disappeared. When the medical coil was moved little by little with the fingertip, the pain at the moved position disappeared immediately. In addition, because of hearing loss, a medical coil was attached after the ear. I felt like it was easier to hear with less noise.
In addition, when the calf was worn, I tried applying a medical coil from the top of the pants, but it was not effective.
(5) A 72-year-old woman. hay fever. When I put a medical coil after my ear, my runny nose immediately stopped.

(6) A 66-year-old man. There was chronic low back pain, and medical coils were affixed to two places where the low back pain occurred. It was pasted for more than a day, but there was no effect.
(7) A 33-year-old man. I had a stiff shoulder and headache after working for a long time. Two medical coils were attached for 6 hours from the shoulder to the neck. My stiff shoulders didn't go away, but my headaches became weaker.
(8) A 58-year-old man. Since there was pain in the scapula, the pain disappeared when the medical coil was attached. Since the pain disappeared, the medical coil was removed, and the same part became painful later. Therefore, the pain disappeared when the medical coil was attached to the corresponding part.

From the above examples, it is very effective for instantaneous cases such as muscle spasms, runny nose, hay fever due to external or internal factors.
On the other hand, it is less effective for chronic cases such as chronic low back pain and shoulder stiffness.

  In addition, a voice was heard that the part where the medical coil was affixed became warm. Therefore, there may be a thermotherapy-like effect.

  As described above, the present invention has been variously described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. is there.
