Description

[Detailed Description of the Invention] The present invention relates to a conductor used in an electronic treatment device such as a low frequency treatment device or a negative potential treatment device.

The electronic therapy device, for example, abuts a conductor with a built-in electrode plate against a part of the human body where pain is felt, and sends pulses generated by a low-frequency generator electrically connected to the electrode plate to the electrode plate. It is possible to suppress pain by applying electrical stimulation to the area where pain is felt.

The electrode plates used in such conductors have conventionally been made of copper,
A metal plate with good conductivity, such as aluminum, or a resin plate on which the metal is adhered or vapor-deposited has been used. Since there is a state of spot conductive contact at the skin contact surface with the human body, the patient will feel pain due to electrical stimulation (hereinafter referred to as pain sensation) before the current reaches the level that suppresses the pain, making treatment impossible. There were many cases where this happened.

In order to overcome this drawback, Japanese Patent Laid-Open No. 55-21931 proposes an electrode plate made of germanium. However, although the use of germanium certainly alleviates the condition of the spot conductive contact, the effect is about twice that of the case using the metal plate.
However, this method could not be used to treat seriously ill patients who require the application of strong electrical stimulation.

The present invention has been devised in view of the above-mentioned prior art, and provides a conductor for an electronic therapy device that does not cause a patient to feel pain even when an electrical stimulation several times higher than that of the prior art is applied. Its main features are: an electrode plate connected to a cord, a moisture-containing and flexible contact placed on the skin-contacting side of the electrode plate, and a frame that holds these. In the electronic therapy device conductor made of a solid body, the electrode plate is formed using a semiconductor inorganic silicon or a hybrid material containing the silicon.

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 show embodiments of the present invention.
2 is an electrode plate electrically connected to a pulse generator (not shown) via a cord 4, and 2 is a contact placed on the skin contact side of the electrode plate 1, which is made of a water-containing and flexible sponge or the like. It is formed. Reference numeral 3 denotes a frame 3 which covers the electrode plate 1 leaving only the skin-contacting surface of the contact 2 and holds and fixes the electrode plate 1 and the contact 2, and is made of rubber or an insulating material. The electrode plate 1 is made of semiconductor inorganic silicon.

Incidentally, by using, for example, single crystal silicon as the inorganic silicon, a preferable effect can be obtained regardless of polarity, but since the single crystal silicon is expensive, it may be used in combination with other substances. If silicon other than single crystal silicon is used, it is preferable to use N-type semiconductor silicon because the potential of the electrode plate 1 is a negative potential. Furthermore, the silicon is the electrode plate 1
It is not necessary to use the adhesive for the entire area, and it may be applied in the form of a thin plate to the upper surface of a plate-like member made of resin or the like, that is, the side that contacts the skin.

FIG. 3 shows a graph comparing the amount of current and the pain sensation value between the present embodiment in which the electrode plate 1 was formed using single crystal silicon and the prior art described above. With the conventionally known conductor (Cu) using a plate, it is painfully felt at 2mA (140V). In addition, in the conventionally known conductor (Ge) using a germanium electrode plate, the voltage is felt at 4 mA (95 V). However, in the conductor (Si) according to this example,
Even at 15 mA (150 V) or more, the pain did not reach the range, and extremely favorable results were obtained. It should be noted that the pain sensation value of this example could not be determined because a general electronic therapy device cannot raise the voltage above 150V, but the difference between the present invention and the conventional technology is clear from the graph shown above. According to the present invention, it is expected that no pain sensation will be produced even if the voltage is increased to 20 mA or more.

As is clear from the explanation of the embodiments described above,
According to the present invention, at least the current flowing to the human body can be reduced.
Even if the voltage is increased to 15 mA or more, the pain sensation value is not reached, so it can be applied to severely ill patients who require strong electrical stimulation, and an extremely desirable lead for electronic therapy devices can be obtained.
