Description

{Low-frequency stimulation with single and multiple electrical outputs}

[0001] The present invention relates to a low frequency stimulator having single and multiple electric outputs, and more specifically, to a single low frequency stimulator (or a low frequency therapy device) having a single common electrode on a surface in direct contact with a human body Frequency pulse having a shape such as a triangular wave, a regular wave, a ladder wave and a square wave is applied sequentially or at various time intervals or simultaneously for a predetermined period of time between the common electrode and each of the working electrodes (Water to water) to stimulate the muscles in various directions irrespective of the direction of muscle formation (that is, the direction of muscle muscle) formed on each part of the body. Stimulation to maximize pain relief and treatment effect, and furthermore, a heat generating means is provided at the central portion of the pad On given relates to a low-frequency stimulation at the same time as the low-frequency treatment by using a heat improve the blood circulation (血 行) and the metabolism of the menstrual blood and moxibustion seat and having a single and multiple electrical outputs the invention to eliminate the fatigue of the nerve and muscle.

In general, a low-frequency therapeutic apparatus (low-frequency therapeutic apparatus) is a device used for treatment of nerves and muscles by applying a low-frequency pulse to a living body. The apparatus has a voltage of 60 to 150 [V] and a voltage of several to several tens of [ Current is supplied through the electrode provided on the pad in the form of a square wave pulse having a frequency of 1 to 500 Hz to treat the nerve or muscle.

In other words, the low-frequency therapy device is a device for stimulating and treating human skin by electric current, and it is a physiotherapy device that was designed to induce all the organs of the external nervous system and the internal nervous system and to prevent all diseases and eliminate the cause .

In addition, the nerve currents and fine refined electronic rhythm of the human body, nervous system movement and blood action by facilitating the metabolism of the human body to functionally control and maintain balance between the body tissue is also functioning.

On the other hand, the pain felt in the human body may be caused by severe stimulation or naturally occurring. Such pain is effective for the treatment of pain by performing low frequency stimulation for 5 ~ 5 ~ 15 minutes two or three times a day Have already been reported in academia.

Therefore, when a low-frequency pulse is applied to a human body by using a low-frequency pulse to stimulate the nerves or muscles, the muscles are loosened and the pain is relieved by the effect of working on the pain or temporal paralysis will be.

Generally, a low frequency of less than 10 Hz stimulates the motor nerve to the extent that it taps lightly by hand, and when the frequency becomes high, And so on.

Most conventional household low-frequency treatment apparatuses are provided with two pads, each of which has one electrode and one electrode provided in one operation and driver.

When treating or stimulating the nerves or muscles of a specific region of the human body by using the low-frequency treatment apparatus for home use having the above-described structure, the upper and lower portions of the muscles having the same direction as shown in Figs. 1 (a) Or the left and right sides of the pad 2, and the operation and driver 1 are operated.

However, the low-frequency treatment apparatus having such a configuration has a configuration in which one electrode (i.e., a single electrode) or a "+" electrode is provided on each pad 2, When a low frequency electric current and a voltage are supplied to the electrode of the pad 2 to give a low frequency electric stimulus to the human body, one electrode per pad is provided so that the therapeutic effect by the low frequency stimulation is not great, , Contraction and relaxation are repeated only in one direction, and irritation does not occur in other adjacent muscles, resulting in a problem that the effect of low-frequency treatment is deteriorated.

On the other hand, thermotherapy (thermotherapy) is widely known as one of physiotherapy means of the human body which improves blood circulation and metabolism by using heat, and eliminates fatigue of nerve and muscles. Promotes blood localization or systemic blood pressure, and alleviates muscle tension and increases analgesia.

As a heat source, hot bath, light ray, electricity and the like are mainly used, and there are a warm bath method, a hot pack, a paraffin bath and the like using an electric conduction heat, and an infrared therapy or an electric bath (electric bath) Electrophoresis such as microwave or microwave is typical, and various physiotherapy methods can also aim at the heating effect.

Such a hyperthermia treatment apparatus is generally used for the purpose of pain, crusting, improvement of blood circulation, softening of muscles and tissues, and since cancer cells are weak at a relatively high temperature compared with normal cells, have.

Normal cells die at 46-47 ° C, while cancer cells die at 39-40 ° C and die at 40-43 ° C, so cancer cells are killed by constantly adding 40-43 ° C heat to the cancer cells.

The local heating method and the whole body heating method are used as the treatment method of cancer through the hyperthermia treatment. In the local warming therapy, electricity is passed to a specific part of the cancer cell, or microwave, high frequency (RF) It is a method to be used when the cancer cells occur only in specific areas.

In addition, systemic hyperthermia is performed for recurrent cancer or advanced cancer, which is likely to have metastasized to other parts of the body. By heating the blood to the heat exchanger and returning it to the femoral vein side, .

However, the conventional low-frequency treatment device or stimulator is not equipped with the hyperthermia treatment device capable of obtaining the above-mentioned effect of the hyperthermia treatment.

In other words, conventionally, low-frequency therapy devices or stimulation devices and hyperthermia therapy devices are separately manufactured, so that low-frequency treatment and hyperthermia treatment can not be simultaneously performed on specific parts of the human body. This is not only an economic burden on consumers, but also takes a lot of time to perform both treatments.

Therefore, when the low-frequency stimulation is applied to a specific region of the human body, the heat generating means 27 is driven simultaneously with the low-frequency treatment or separately from the low-frequency treatment, ) Can be performed by using the heat of 40 ~ 50 캜 generated from the blood circulation and moxibustion to improve the blood circulation and metabolism of the moxibustion and eliminate the fatigue of the nerve and muscles, Can further increase the effect of hyperthermia treatment.

In addition, the usability of the low-frequency stimulator itself can be greatly improved, and since the consumer need only have one low-frequency stimulator, it is possible to reduce the economic burden, and the time required to perform the low-frequency and hyperthermia treatment can be greatly reduced .

In the present invention, as described above, only two power supply lines 16 and one control signal transmission line 17, to which a power supply voltage is supplied together with a low-frequency signal, between the operation and driver 1 and the pad 2, And can be detachably coupled through the male connector. Thus, the production cost of the product can be reduced, and the failure rate and the like, which may occur due to disconnection of the power supply line and the control signal transmission line, And the connection between the driver 1 and the pad 2 are very simple, so that the operability and usability of the user can be greatly improved.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Which will be apparent to those skilled in the art.
