[0001] ELECTRIC STIMULATOR FOR MUSCLES AND JOINTS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-frequency device, and more particularly, to a variable-type low-frequency device for relieving muscle and joint pain that stimulates muscles and joints by bringing a conductive contact pad into contact with skin and flowing a low-

Recently, public interest in health has been increasing day by day, and a variety of devices for health promotion have been developed and widely spread to the general public.

A low frequency device is a medical device that draws a low frequency current generated from a low frequency generator to a conductive contact pad brought into contact with the skin to stimulate muscles, tendons, ligaments, etc. to obtain a therapeutic effect.

In recent years, attention has been paid to the fact that muscle stimulation using a low frequency device brings about the same effect as weight exercise, and low frequency devices are widely used as exercise devices for directly stimulating muscles.

As a conventional technique for such a low-frequency device, Korean Utility Model Registration No. 20-0392565 entitled "Low-Frequency Therapy Device" (Registered Aug. 3, 2005), Korean Patent Publication No. 10-2014-0114190 " Therapeutic Stimulator "(published on September 24, 2014), Korean Patent Publication No. 10-2015-0105062" Diet and Therapy Belt Utilizing Low Frequency Pads "(disclosed on September 16, 2015).

The low frequency device includes a plurality of conductive contact pads paired to be in contact with the skin and a low frequency generator for flowing a fine low frequency current through the conductive contact pads.

1 is a conceptual diagram of a low-frequency device according to a conventional technique.

In the case of the low-frequency device shown in FIG. 1, two wires 2 extending from the low-frequency generator 1 are connected to the conductive contact pads 3 so that the pair of conductive contact pads 3 can be freely attached to the body parts. A conductive contact pad 3 is coupled.

These types of low-frequency devices are most widely used in hospitals and homes, and the conductive contact pads 3 are freely connected to the two wires 2, so that the user has to lie down on the bed or the chair to use it.

In order to perform physical activities while wearing them, the conductive contact pad 3 should be fixed to the body by using a band or a belt, and the low frequency generator 1 connected to the electric wire 2 should be held by hand or stored in a pocket or the like .

FIG. 2 is a conceptual diagram of another conventional low-frequency device, and FIG. 3 is a conceptual cross-sectional view of the low-frequency device of FIG.

2 is a low-frequency exercise device for stimulating muscles to obtain a movement effect. The low-frequency generator 4, which generates a low-frequency current, is small in size and integrated with the conductive contact pad 5, Physical activity is possible.

Since such a compact type low frequency device is manufactured in accordance with the fixed muscle type, it is generally used for specific areas such as abdominal muscles and thigh muscles. It is also used to obtain the effect of exercise mainly through muscle stimulation rather than pain relief or treatment.

That is, it is difficult to use it universally, and there is a problem that it can not be used in a part where the body is folded or protruded like a joint.

On the other hand, in such a compact type low frequency device, since the conductive contact pad 5 is integrally provided in the low frequency generator 4, it can not be detached and replaced if the conductive contact pad 5 is damaged.

Korean Registered Utility Model No. 20-0392565 entitled "Low Frequency Therapy Device" (registered on Aug. 3, 2005) Korean Patent Laid-Open No. 10-2014-0114190 entitled "Electric Therapy Stimulator for Deep Muscle Stimulation" (disclosed on September 24, 2014) Korean Patent Publication No. 10-2015-0105062 "Diet and therapeutic belt utilizing low-frequency pads" (disclosed on September 15, 2015)

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

FIG. 7 is a conceptual cross-sectional view of a variable-type low-frequency device for relieving pain of the muscles and joints of FIG. 4;

A variable type low-frequency device (hereinafter referred to as a variable type low-frequency device) for relieving muscle and joint pain according to an embodiment of the present invention includes a low-frequency generator 100 for generating a low-frequency current, a pair of contacts Pad 200 as shown in FIG.

The low frequency generator 100 is for generating a low frequency current to emit a low frequency current to the contact pad 200.

On the upper surface of the low frequency generator 100, an operation button 110 for adjusting the intensity of on / off and low frequency current is provided.

A battery for driving the low frequency generator 100 is mounted in the low frequency generator 100 and a battery cover 120 provided on the lower surface of the low frequency generator 100 is detachably mounted on the battery. The low frequency generator 100 may be manufactured as a rechargeable battery integrated type according to the embodiment.

A plurality of contact pad coupling terminals 130 for radiating the generated low frequency current to the contact pads 200 are provided on the lower surface of the low frequency generator 100. The contact pad coupling terminal 130 is for rotatably coupling the contact pad 200. [

In this embodiment, a pair of contact pad coupling terminals 130 are provided so as to be spaced laterally. According to an embodiment, the contact pad coupling terminals 130 may be provided in two or more pairs.

The contact pad coupling terminal 130 of the present embodiment is a metal female snap button having an insertion groove 131 formed therein. The low frequency generator coupling terminal 220 of the contact pad 200, which will be described later, corresponds to the contact pad coupling terminal 130 is a metallic snap button that is coupled to the female snap button.

Since the contact pad coupling terminal 130 and the low frequency generator coupling terminal 220 are rotatably coupled to transmit a low frequency current, the female / male snap buttons can be interchanged.

The contact pads 200 are coupled to the two contact pad coupling terminals 130, respectively. The contact pad 200 has a narrow width at one side and a wide width at the other side and is rotatably coupled to the contact pad coupling terminal 130 about the contact pad coupling terminal 130.

The contact pad 200 includes a pad body 210 made of a flexible flexible material, a low frequency generator coupled to the pad body 210 and rotatably coupled to the contact pad coupling terminal 130 of the low frequency generator 100, A conductive electrode unit 230 provided on the lower surface of the pad body 210 and a conductive adhesive unit 240 provided on the lower surface of the conductive electrode unit 230.

The pad body 210 is made of a flexible material so that it can be bent in a shape corresponding to the contact portion. For example, it can be made of rubber, silicone, or fabric material.

The low frequency generator coupling terminal 220 is provided on one side of the pad body 210. The low frequency generator coupling terminal 220 is a metal snap cap as described above so that the insertion protrusion 221 to be inserted into the insertion groove 131 of the contact pad coupling terminal 130 protrudes upward, .

The low frequency generator coupling terminal 220 rotatably couples the contact pad 200 to the contact pad coupling terminal 130 and is electrically connected to the contact pad coupling terminal 130 to be generated in the low frequency generator 100 Frequency current to the human body through the conductive electrode unit 230. [

A conductive electrode unit 230 made of carbon is provided on the lower surface of the pad body 210. The conductive electrode unit 230 has a wide spread shape corresponding to the pad body 210. The conductive electrode portion 230 contacts the low frequency generator coupling terminal 220 and is energized. Since the carbon electrode 230 is excellent in conductivity, the low-frequency current transmitted through the low-frequency generator coupling terminal 220 can be effectively transmitted to the human body.

The conductive electrode unit 230 only needs to transmit a low-frequency current evenly to the human body, so that the material and the shape are not particularly limited.

The conductive adhesive part 240 is provided on the lower surface of the conductive electrode part 230 to adhere to the user's skin and to transmit the low-frequency electric current delivered to the conductive electrode part 230 to the human body.

The conductive adhesive portion 240 of this embodiment is a conductive hydrogel. The conductive hydrogel is a hydrophilic polymer material and has properties very similar to biological tissues. Therefore, when the contact pad 200 is brought into contact with the skin through the conductive adhesive part 240, the same effect as that in which the conductive electrode part 230 is directly in contact with the skin is obtained.

In addition, the conductive adhesive portion 240 made of conductive hydrogel is not completely adhered to the skin, and thus can be easily detached and used repeatedly as long as it is not contaminated by foreign matter.

A release paper (not shown) is attached to the lower surface of the conductive adhesive portion 240. The peeling is for preventing foreign matter from sticking to the adhesive surface of the conductive adhesive portion 240 and is not shown separately because it is used for conventional low frequency devices as well.

FIG. 8 is a view showing a use state of a variable type low frequency device for relieving pain of muscles and joints according to an embodiment of the present invention. FIG.

As described above, the contact pad 200 is of a fan shape having a narrow width at one side and a wide width at the other side. The low frequency generator coupling terminal 220 provided at one side is inserted into the contact pad coupling terminal 130, 200 and the low frequency generator 100 are combined.

Since the contact pad coupling terminal 130 is in the form of an arm snap button and the low frequency generator coupling terminal 220 is in the form of a male snap button, the contact pad 200 is rotatable in the horizontal direction while being coupled to the low frequency generator 100 Do. That is, the attitude of the contact pad 200 relative to the low frequency generator 100 can be changed by rotating each contact pad 200.

The two contact pads 200 should be in contact with the skin in a state in which they are spaced apart from each other and therefore should not interfere with each other. As described above, the contact pad 200 according to this embodiment has a fan-shaped shape with one side being narrower than the other side, so that interference with other contact pads is minimized even if the two contact pads 200 are rotated to some extent. That is, the sector shape of the contact pad can maximize the rotation range of the contact pad 200, that is, the posture change range.

When the shape of the variable type low frequency device according to the present embodiment is modified by rotating the contact pad 200, the two contact pads 200 can be easily attached to a part where the body is folded or protruded like a joint.

Particularly, since the conventional low-frequency device, in which the contact pads are fixed in a straight line, can be easily used on parts such as neck, shoulder, cuff, and elbow which are difficult to attach,

Therefore, it can be used universally for stimulating the joints and ligaments of the joints, which have been difficult to stimulate with conventional low-frequency devices, in order to alleviate the pain, or to strengthen specific muscles.

In this embodiment, a pair of contact pads 200 is provided, but this is merely an example. But may be implemented in the form of providing two or more pairs of contact pads 200 according to an embodiment.

It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .

It is therefore to be understood that the above-described embodiments are illustrative in all aspects but are not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
