Description

TECHNICAL FIELD [0001] The present invention relates to an electric cable, a method of manufacturing the same, and a surface member for an electric stimulation system having the electric cable,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cable, a method of manufacturing the same, and a planar body for an electric stimulation system having the same. More particularly, the present invention relates to an electric cable, And more particularly, to an electric cable, a method of manufacturing the same, and a planar body for an electrical stimulation system having the same, which can improve durability because it can prevent damage or deformation.

In general, an electric stimulation system is a system for applying electrical muscle stimulation (EMS) to stimulate muscles directly by a current supplied from a power supply unit and thereby to retract muscles without a brain command, Because it induces contraction of muscle fiber itself electrically without weight training or big action, exercise effect can be demonstrated without damage of ligament or joint, so weight control, body correction and rehabilitation effect can be expected.

When the electric stimulation system supplies electric current to the stimulation applying member in contact with the human body, the electric stimulation is applied to the skin tissue or the subcutaneous tissue, thereby promoting blood circulation, thereby enhancing the therapeutic effect and cosmetic effect.

As the electric stimulation system described above, Korean Patent Registration No. 10-1114164 proposes a 'wearable EMG and functional electrical stimulation system' as shown in FIG.

The above-described clothes type EMG and functional electrical stimulation system includes an EMG-functional electrical stimulation apparel 10, an EMF-functional electrical stimulation main body 200, and a portable terminal unit 100.

The clothes 10 for EMG-functional electrical stimulation are composed of a lining and a surface material, and are equipped with stimulating electrodes and electromyogram electrodes on the inner side of the lining, that is, portions contacting with the skin. In the electromyographic- (Signal line, power line, ground wire, etc.) connected to the electromyographic electrodes are embedded between the lining and the outer surface.

EMG - at least the lining of the functional electrical stimulation apparel is made of elastic material, and the wires are embedded between the lining and the outer surface, so that the wearer does not interfere with movement of the wire during exercise or activity.

The EMG-functional electrical stimulation apparel 10 can be made up of a top and bottom and, in some cases, a one-piece style.

The electromyographic-functional electrical stimulation main body 200 controls the stimulation electrodes and the electromyographic electrodes mounted on the contact area of the skin inside the garment 10 for electromyographic-functional electrical stimulation. The electromyographic-functional electrical stimulation main body unit 200 is driven by the main body battery 290 and has a body key input unit for turning on / off the power, setting the intensity of the stimulation, etc., .

The portable terminal unit 100 is difficult to control the electromyographic-functional electric stimulation main body 200 mounted on the clothes worn by the caregiver or the physical therapist while the protector or the physical therapist assists the physical therapy, It is a prepared device for this purpose. The portable terminal unit 100 includes a terminal key input unit for performing power on / off, setting the intensity of a stimulus, and transmits the input signals to the electromyographic-functional electric stimulation main unit 200 wirelessly. Also, information such as the electromyogram of the patient received from the electromyographic-functional electrical stimulation main body 200 is displayed on the terminal display unit, and is driven by the terminal battery.

Meanwhile, the above-described electric stimulation clothing 10 is fabricated by cutting a fabric, sewing it, fabricating a garment body, fixing the electric wire to the installation position of the stimulation electrode installed on the body of the garment, sewing it, And a stimulating electrode is provided on the garment body. At this time, the magnetic pole electrode is electrically connected to the electric wire so that an electric signal can be transmitted from the outside.

Electrode electrodes are generally made of an electrode surface material in which a fabric is coated with a conductive polymer or the like, and wires are made of metal wires of fine strands without an insulating layer.

However, as described above, since the electric wire has low insulation property, if the wearer develops a secretion such as sweat due to exercise or activity, the electric wire can not properly apply electric stimulation due to a short circuit and cause malfunction.

In addition, since the above-described conventional electric wires are formed by joining metal wires, metal wires are damaged due to repetitive friction during use, and durability is deteriorated due to corrosion caused by secretions.

In addition, since the conventional wire is easily damaged by the needle during the process of fixing the wire to the garment body using the staple, there is a limit in that a defective product is generated.

In addition, the conventional wire described above has a structural weakness that is easily damaged when the electric stimulation clothing 10 is frequently washed due to contamination.

Particularly, when the conventional wire is to be replaced due to disconnection, it is difficult to replace the wire because the electric wire is totally cut off from the garment body and it takes a long time, which is expensive and maintenance cost is too high. It is not only impossible to use but also has a limit of shortening the use period because it causes damage or deformation of the clothes for electric stimulation due to frequent stitching.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2A to 11, and the same reference numerals are given to the same constituent elements in FIGS. 2A to 11B. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

2A is a perspective view showing an electric cable according to a first embodiment of the present invention.

2A, an electric cable c according to a first embodiment of the present invention includes a conductive member 1 having a linear structure in which power is supplied and an insulator 2 having the conductive member 1 embedded therein The conductive member 1 is improved in electrical insulation characteristics to improve the stability of operation and the conductive member 2 is prevented from being damaged even when an external force is applied and the conductive member 2 can be easily replaced even when it is damaged .

For this purpose, the insulator 2 is composed of a hollow body having a hollow portion 21 formed along the longitudinal direction thereof, and has a longitudinal sectional area of the hollow portion 21 (a hollow portion area in a state of being cut in a direction orthogonal to the longitudinal direction of the insulator Is formed to have a cross-sectional area larger than the longitudinal cross-sectional area of the conductive member 1.

For example, the insulator 2 is composed of a stretchable insulator which is stretched when an external force is applied. The stretchable insulator may be composed of a stretchable tube formed of various stretchable polymer resins having stretchability, but in the present embodiment, it is typically formed of a known silicone rubber. Herein, the silicone rubber is a rubber elastomer which is crosslinked by mixing a highly-polymerized straight-chain diorganopolysiloxane with fine silica or the like as a reinforcing agent, and is excellent in stretchability and waterproofness.

The conductive member (1) is typically applied to a conductive member (11) capable of conducting electricity. Although only one strand may be disposed for the conductive yarn, it is preferable to apply a bundle of plural strands of conductive yarn having a relatively small diameter so as to have flexibility.

The conductive yarn 11 is selected by applying a yarn formed of a conductive material or a fiber yarn including a conductive material.

In this case, a metal sheet made of a conductive metal, carbon yarn, or the like, which is formed of a conductive material, can be applied, but a conductive metal sheet such as stainless steel, titanium, or copper can be typically used. At this time, the conductive metal yarn having a diameter in the range of 10 to 500 micrometers (탆) is applied so as not to be easily damaged even if the conductive metal yarn is inserted into the insulator 2 or stitched on a fabric or the like.

The fiber yarn including the conductive material is a yarn used for spinning the fiber yarn so that a conductive material such as conductive metal nano-particles, metal oxide particles, graphene and the like is included in a plurality of filament yarns constituting the fiber yarn. A fiber yarn in which a conductive material is contained in a batch and is spun or a conductive polymer is coated on a fiber yarn is applied.

On the other hand, the conductive member 1 is arranged so as to have a plurality of bent portions inside the hollow portion 21. [ As shown in Fig. 2A, when the conductive member 1 is placed at both ends of the same length and the elastic tube is contracted, as described in detail later in the manufacturing method, The conductive member 1 is arranged so as to have a plurality of bent portions while being drawn in the hollow portion 21 as shown in Fig.

Hereinafter, a method of manufacturing the electric cable according to the first embodiment of the present invention will be briefly described.

2B is a schematic view for explaining a method of manufacturing an electric cable according to a first embodiment of the present invention.

The method for manufacturing an electric cable according to the first embodiment of the present invention is manufactured by sequentially performing a conductive member inserting step, a stretchable insulator stretching step, and a conductive member arranging step.

The conductive member inserting step is a step of inserting the conductive member 1 prepared in advance into the hollow portion 21 of the flexible insulator 2 as shown in part (a) of FIG. 2B, It is preferable to insert a cut so that the length of the stretchable insulator 2 is slightly longer than the length of the stretched insulator 2 in the elongated state.

The stretchable insulator stretching step may be performed by simultaneously fixing one end of the flexible insulator 2 and one end of the conductive member 1 and holding the other end of the flexible insulator 2 at the same time as shown in part (b) In a way that it works by stretching.

2B, the other end of the flexible insulator 2 and the other end of the conductive member 1 are simultaneously fixed (p2) after the stretchable insulator stretching step is performed, as shown in FIG. 2B, The tensile force applied to the flexible insulator 2 is released to shrink the flexible insulator as shown in part (d) of Fig. Here, the fixing method of the conductive member 1 and the insulator 2 can be performed manually, but it is preferable to use a clamp device configured to perform clamping and unclamping operations by an actuator for mass production .

When the conductive member arranging step is performed, the conductive member 1 contracts together with the flexible insulator 2. At this time, since the conductive member 1 is a bundle of the conductive parts 11 that can not be expanded or contracted, As shown in Fig. 4A, and is arranged to have a plurality of bent portions inside the hollow portion. Thereafter, when the restraining force applied to both the fixing points p1 and p2 of the flexible insulator 2 and the conductive member 1 is released, an electric cable c of the type shown in FIG. 2 (e) is manufactured .

Figs. 3A to 3E are views for explaining another embodiment of the conductive member applied to the electric cable according to the first embodiment of the present invention, wherein the enlarged portion is a perspective view enlarging a part of the conductive member. Fig.

Referring to FIG. 3A, the conductive member 1 is formed in such a structure that the conductive yarn 11 is wound on the outside of the center yarn 12. At this time, the center yarn 12 is composed of a fiber yarn in which a plurality of filament yarns are folded, and a high-tension fiber yarn such as an aramid yarn is selected and disposed as the yarn.

3A, when the external force such as a tensile force is applied to the conductive member 1, the center yarn 12 disposed inside the conductive member 1 sustains an external force, thereby preventing breakage of the conductive yarn 11 .

Referring to FIG. 3B, the conductive member 1 is formed in such a structure that a conductive adhesive 11 having conductivity is wound around the center yarn 12a. The center yarn 12a is formed as a stretchable yarn. The stretchable core yarn 12a is a stretchable polymer yarn called spun yarn, polyurethane yarn, or the like, and is made of a stretchable polymer resin formed of polyimide, polyester, polyethylene terephthalate, Can be applied.

The conductive member 1 shown in FIG. 3B has a structure in which the center yarn 12 is stretched when the external force such as tensile force is applied and the conductive yarn 11 is also wound around the center yarn 12a because the center yarn 12a is composed of the stretchable polymer yarn. So that it can be spread or contracted, so that it is possible to prevent breakage of the conductive yarn 11.

Referring to FIG. 3C, the conductive member 1 has a plurality of protective yarns 13 wound on the outside of the conductive yarn 11, and the protective yarns 13 have different diameters so that the protective yarn 13a having a large diameter is wound And a section in which the protective tape 13b having a small diameter is wound is alternately arranged.

The conductive member 1 shown in FIG. 3C is bent in a state of being bent to have a plurality of bends, and when the bending phenomenon occurs, the protective member 13a having a small diameter is bent, Since the surfaces of the conductive parts 11 of the folded parts are electrically contacted with each other, problems such as changes in electrical resistance, wear and the like can be solved and an excessive bending phenomenon of the conductive yarn can be prevented in advance There is an advantage that the durability can be improved.

Referring to FIG. 3D, the conductive member 1 is formed in a structure in which a conductive conductive member 11 is wound in a coil structure.

The conductive member 1 shown in Fig. 3D is manufactured in such a manner that the conductive yarn 11 is wound around the center yarn 12c in a coil structure and then the center yarn 12 is removed. At this time, the center yarn 12c performs a function of a support line for easily winding the conductive yarn 11. The core yarn 12c can be removed by physical, chemical, and optical processing so as to be removed after the conductive yarn is wound It is composed of the formed shipmen.

For this purpose, the center yarn 12c is made of a low-melting-point fiber yarn which melts at a lower temperature than the electric conductor 11, a photodegradable fiber yarn which is decomposed when irradiated with light, an organic solvent-decomposable fiber yarn which is decomposed upon contact with the organic solvent, And may be selected from among water-decomposable fiber yarns that are degraded upon contact.

For example, the photodegradable fiber yarn can be constructed by applying a pre-warp yarn that is decomposed upon irradiation with light, such as a photodegradable PP resin containing a photocatalyst material such as titanium oxide (TiO2) or a pre-warp drawn using a PE resin. If the photodegradable fiber yarn is removed in such a manner that the lamp for irradiating light is brought close to the conductive member 1 applied as the center yarn 11c, only the coiled-up conductive member 11 remains.

When an organic solvent-decomposable fiber yarn that is decomposed when the core yarn 11c is brought into contact with an organic solvent is applied, it may be constructed by applying polyvinyl chloride yarn that is decomposed into acetone or polystyrene yarn that is decomposed into thinner or ethylene . When the organic solvent-decomposable fiber yarn is applied to the core yarn 11c as described above, the corresponding solvent that chemically reacts with the center yarn 11c can be removed by spraying the core yarn.

In addition, the center yarn 11c can be a yarn extracted from a water-decomposable material decomposed upon contact with water such as pulp. Typically, PVA fiber (Poly Vinyl Alcohol, unprocessed after emulsification in cell liquid) can be applied. In other words, PVA fiber is a filament yarn which is made by spinning a poval and spinning it with a spinning method similar to rayon.
