The present invention relates to a massage device, and more particularly, to a low frequency massage device for carrying out massage by energizing a low frequency current through a human body.

The massage of low frequency current is very effective for muscle pain, shoulder muscles, pain and low back pain, and blood circulation.

The inventors of Japanese Patent Application Laid-Open No. 1-56060 disclose that in such a massage, the ratio of the constant voltage division voltage component in one wave of the pulse is 0.1: 1-0.5: 1 in the range of pulse voltage, in particular, stimulated. Ideally, the potential voltage similar to that seen in nerves is described as the most suitable pulse voltage. However, these pulse voltages are energized by the human body and have a very good massage effect, but the negative voltage component is weak with respect to the constant voltage component. As large as 2-10 times, in case of energization, this negative voltage component is applied to the part other than the affected part through the non-conducting conductor (generally, the plug connected to the non-electrode electrode and the plug connected to the output terminal), which leads to undesirable pain. It turned out.

In view of such a situation, the inventors of the present invention have a low voltage that can conduct a comfortable massage with less pain by energizing a pulse voltage in which a constant voltage component and a negative voltage component are not the same, especially a pulse voltage having a larger negative voltage component than a constant voltage component. A massage device was carefully examined.

As a result, an electrode having a flat head and an electrode having a new head can be attached to the outer wall of the main body of a low frequency massage device at an appropriate interval, and at the same time, the electron electrode is connected to a low potential output terminal of a low frequency oscillator. It has been found that the problem can be solved by a low frequency massage device in which the latter electrode is connected to a high potential output terminal and covered with a cover member in which the heads of these electrodes are formed in a substantially spherical shape.

In other words, the present invention attaches the electrode having the head flat to the outer wall of the main body and the electrode having the head shaped in the form of an interval at an appropriate interval, and simultaneously attaches the former electrode to the low potential output terminal of the low frequency oscillation circuit. The structure of the low frequency massage apparatus characterized by connecting to the high potential output terminal and covering the head of these electrodes with the cover member formed in the shape of a circle was made into the summary.

Next, the present invention will be described according to the illustrated embodiments. [0021] FIGS. 1 and 2 are side views showing part of a perspective view showing the appearance of an embodiment according to the present invention, respectively.

(5) (5) is an electrode for applying a low frequency voltage to the human body, and generally uses a metal material such as stainless steel to form the head flat or in an acid shape, and at the same time, the inner thread inside the leg part (4) (4) In order to engrave the threaded portion corresponding to this and attach it to the main body 1, the threaded portion is threaded to the inner threaded screws 4 and 4.

As the head shape of the electrodes (5) and (5), the head of one electrode is provided with a flat portion of a suitable shape such as a circle or a square, and the head of the other electrode is, for example, a mushroom, a semi-spherical shape, a bowl shape, a trapezoid shape, It is preferable to form a cone shape such as a cone shape, a pyramidal shape, and a visible shape so that the top area of the former electrode becomes larger than the latter electrode. As shown in FIG. The flange-shaped portion of the head is installed to prevent the cover member (6) (6) from easily falling off during use and stopping or losing the energized massage.

When such an electrode having a flat head is connected to the low potential output terminal of the low frequency oscillator to form an uncorrelated electrode, unpleasant pain does not occur in a portion other than the affected part. In addition, when the electrode formed in the head shape is connected to the high potential output terminal of the low frequency oscillation circuit to form a therapeutic electrode, it is easy to energize so-called acupuncture points.

(6) (6) is a cover member for covering the heads of the electrodes (5) and (5), and generally forms absorbent materials such as sponges and fabrics, and conductive materials such as ceramics and conductive rubber in a substantially spherical shape. The recessed part corresponding to the head shape of the electrodes 5 and 5 is provided.

In particular, the cover members 6 and 6 are detachably attached to the heads of the electrodes 5 and 5, and at the same time, the cover members 6 and 6 are smoothly replaced when worn or soiled by repeated use. Not only can it be done, but it is easy to change the cover member of the most suitable material and size according to, for example, symptoms, shape, size, etc. to be treated. In addition, when the conductive rubber is formed into a substantially spherical shape to form the cover members 6 and 6, the molding is easy and the adhesion to the electrode head is smooth and secure, and the skin does not wear or become dirty even after repeated use. It is also possible to make the current conduction characteristic to extremely excellent.

(7) is a low frequency oscillation circuit for generating a low frequency voltage, and is usually housed inside the main body 1 together with a battery or the like not shown in the drawing, and an electrode having a flat head at its low potential output end is also a high potential output end. An electrode in which the head is formed in the form of a mountain is connected.

As the low frequency oscillation circuit 7, for example, the present inventors have a ratio of about 0.1: 1-0.5: 1, preferably about 0.2: 1-0.3: 1, of one pulse of a pulse disclosed in Japanese Patent Application Laid-Open No. 1-56060.

The time t _n is about 0.001-0.1 seconds, preferably about 0.002-0.05 seconds, the duration of the constant voltage component e _p (t _p ) and about 1.1-2.0 times preferably about 1.4-1.6 times It is most suitable to oscillate a pulse voltage of about 1 / 100-1 second, preferably with a pause time t _s of about 1 / 400-10 seconds. Such a low frequency oscillation circuit is disclosed in, for example, Japanese Patent Application Laid-open No. In accordance with the circuit shown in Fig. 1, elements such as transistors, resistors, capacitors, and transformers are combined or integrated. For example, it is preferable to combine a multivibrator, an operational amplifier and these elements, or to integrate the whole low frequency oscillation circuit. If necessary, as shown in FIG. 1, for example, as shown in FIG. By installing the volume with the switch (9), the user can freely open and close the low frequency oscillation circuit or the oscillation frequency can adjust the output voltage.
