FIG. 2 is a graph showing a change in VAS with respect to discomfort caused by pain.

Hereinafter, the present invention will be described in more detail.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a," "an," and "the" include singular forms unless the context clearly dictates otherwise. Also, " comprise "and / or" comprising "when used herein should be interpreted as specifying the presence of stated shapes, numbers, steps, operations, elements, elements, and / And does not preclude the presence or addition of one or more other features, integers, operations, elements, elements, and / or groups.

The present invention relates to a taping sheet which does not cause skin troubles such as allergy by using a base substrate and a biocompatible hydrogel adhesive layer having optimal stretching conditions.

The taping sheet according to the present invention includes a base substrate and an adhesive layer coated on one side of the base substrate, so that the adhesive layer can be attached to the skin for use.

The base material is present on the adhesive layer to support the adhesive layer and has stretchability to support the movement of muscles and to relax or contract the muscles by having an axial capacity similar to that of the skin and muscles.

In the present invention, the base substrate is characterized in that the thickness of the longitudinal seal is 5 to 10 times thicker than the thickness of the transverse seal. That is, since the thickness of the longitudinal seal is thicker than that of the transverse seal, the taping sheet using the base material can be easily expanded and contracted in the longitudinal direction (transverse seal direction), but is less likely to be stretched in the thickness direction do.

That is, the taping sheet according to the present invention satisfies an expansion / contraction ratio in the longitudinal direction with respect to the thickness direction of 1.2: 1 to 1.5: 1. For this purpose, the thickness of the longitudinal seal is preferably 5 to 10 times greater than the thickness of the transverse seal used as the base substrate. If the thickness is out of the above range, the longitudinal stretch ratio in the thickness direction is in the range of 1.2: 1 can not be satisfied. As described above, if the thickness of the transverse thread and the longitudinal thread of the base material is out of the range, the problem of skin trouble of the conventional taping sheets can not be solved.

When the taping sheet according to the present invention satisfies the stretch ratio in the longitudinal direction with respect to the thickness direction of 1.2: 1 to 1.5: 1, if the taping sheet is stuck according to the muscle shape or the direction of the pain, Can be maximized.

The taping sheet according to the present invention preferably forms an adhesive layer in the form of a hydrogel made of hydrophilic polyvinyl alcohol on one side of the base substrate. Specifically, a hydrophilic polyvinyl alcohol having a weight average molecular weight of 10,000 to 1,000,000 g / mol is prepared in the form of a hydrogel by repeating the freezing and thawing process several times and then applied with an adhesive layer.

When a hydrogel made of biocompatible polyvinyl alcohol is used as an adhesive layer, it is useful because it does not cause skin troubles such as allergy, and because it has a hydrogel shape physically crosslinked by a freezing and thawing process, It is preferable because it has physical properties.

In addition, the adhesive layer of the taping sheet according to the present invention may further comprise at least one selected from the group consisting of copper, aluminum, carbon, iron, gold, silver, zinc, platinum, nickel, cobalt, cadmium, chromium, magnesium, It is preferable to include at least two kinds of materials having different potentials from each other.

The electrochemical potential is called the reversible potential and the electromotive force series. The more ionized metal, the lower the electrochemical potential, and the better the metal, the higher the electrochemical potential. For example, the electrochemical potential of iron (Fe) is -0.440V, aluminum (Al) is -1.662V, and Fe has a potential as high as about 1.2V.

In the present invention, when at least two kinds of substances having different electrochemical potentials are mixed and used, the two kinds of substances are in direct contact with the skin of the human body. At this time, moisture is contained in the adhesive layer due to perspiration contacted from the skin, and a minute current flows between the two kinds of substances having a potential difference due to the moisture. This fine current has the effect of stimulating the flow of blood or body fluids by activating the cells of the portion to which the taping sheet is adhered.

In addition, the fine electric current can be generated more as the kinds of substances having different electrochemical potentials included in the adhesive layer of the present invention are increased, and the effect of stimulating the flow of blood or body fluid can be further enhanced.

In the present invention, the term 'a material having a different electrochemical potential' means a material having a difference of about 0.5 or more between the electrochemical potentials of the two materials, and the larger the electrochemical potential difference is, the greater the effect can be.

As described in the present invention, when a minute current flows through the human body due to two or more substances having different electrochemical potentials contained in the adhesive layer, the cells of the portion are activated and circulation of blood and body fluid is improved. As a result, The pain can be alleviated.

More preferably, the adhesive layer of the present invention is coated with 0.5 to 2 g of two or more kinds of substances having different electrochemical potentials per unit area (cm 2) to stimulate the flow of blood or body fluids, In order to alleviate the problem. If the amount of the two or more kinds of substances having different electrochemical potentials per unit area (cm 2) contained in the adhesive layer is less than 0.5 g, the effect is insufficient, and if it exceeds 2 g, the adhesive strength of the adhesive layer may be deteriorated.

In addition, it is preferable that the base substrate according to the present invention is waterproof coated on one side not contacting the adhesive layer. The waterproof coating can prevent the water from being absorbed into the base substrate even if the waterproof coating is applied to the skin of a human and sweating from a human body or contacting the taping sheet with water, The adhesive force can be kept good.

The waterproof coating can be carried out by a known method. For example, a water repellent agent aqueous solution is applied on one side of the base substrate that does not come in contact with the adhesive layer, or a roller is used to apply an aqueous solution of a water repellent agent to one side of the base substrate And the like, but the method is not particularly limited.

The waterproof coating may use at least one material selected from a fluorine-based waterproofing agent, a silicone-based waterproofing agent, a wax-based waterproofing agent, a zirconium-based waterproofing agent, an ethylene urea-based waterproofing agent, a methylolamide-based waterproofing agent, and a pyridinium salt-based waterproofing agent, Among these, a wax-based waterproofing agent is preferable, and paraffin wax is particularly preferable.

In the method of manufacturing the taping sheet according to the present invention, first, a base substrate having a thickness of 5 to 10 times thicker than the thickness of the transverse seal is prepared. Preferably, the fabric of the base material is made of stretchable polyurethane 70 denier fabric, and the longitudinal yarns are fabricated by intersecting two yarns using 14, 15 or 16 cotton surfaces. In this case, it is important that the thickness of the longitudinal seal is 5 to 10 times thicker than the thickness of the transverse seal.

An adhesive layer is formed on one surface of the prepared base substrate, and the adhesive layer includes two or more kinds of substances having different electrochemical potentials.

The adhesive layer of the present invention is preferably a hydrogel adhesive layer prepared by freezing and thawing hydrophilic polyvinyl alcohol having a weight average molecular weight of 10,000 to 1,000,000 g / mol.

The polyvinyl alcohol is preferably prepared in an aqueous solution of 1 to 40% by weight, more preferably 10 to 20% by weight, in deionized water as a solvent. If the concentration of the polyvinyl alcohol aqueous solution is less than 1 wt%, there is a problem that a hydrogel having too low physical properties is formed. When the concentration exceeds 40 wt%, the viscosity of the prepared solution is too high, .

The prepared polyvinyl alcohol aqueous solution is poured into a mold, frozen at a temperature range of 0 ° C to -250 ° C, and thawed at a temperature of 1 ° C to 50 ° C to prepare a polyvinyl alcohol hydrogel. In the present invention, the physical crosslinking method of freezing-thawing may be repeatedly performed three to four times.

In addition, in order for the two or more kinds of materials having different electrochemical potentials to contact with moisture to allow a minute current to flow, it is preferable that the material is not completely embedded in the adhesive layer but is exposed to the outside. In addition, the two or more kinds of substances having different electrochemical potentials are applied in an amount of 0.5 to 2 g per unit area (cm 2) to stimulate the flow of blood or body fluid, and to promote the self-healing power to maximize the effect of relieving pain .

Therefore, in the present invention, it is more preferable to apply two or more kinds of substances having different electrochemical potentials by spraying or the like, after the adhesive layer is applied to one surface of the base substrate and before the adhesive layer is dried.

The taping sheet according to the present invention can be used for any part of the shoulder, head, elbow, hands, fingers, chest, back, abdomen, waist, femur, hip, thigh, knee, calf or foot. In addition, it can be used for emergency treatment after an accident such as a sprained area, a puncture, a dislocation, or the like where pain is felt every exercise. In the case of prevention of disturbance by sports and the case where pain is severe, the effect is large when two taping tapes are crossed and adhered to each other.

Further, since the taping sheet according to the present invention is free from wrinkles or lifting or peeling off from the body, it can be used on clothes, and the adhesive layer is not adhered to the clothes, Can be used.

The size and shape of the taping sheet of the present invention can be appropriately changed in accordance with a predetermined tacky portion and can be appropriately changed and attached according to the shape of the muscle.

Hereinafter, preferred embodiments of the present invention will be described in detail. The following examples are intended to illustrate the present invention, but the scope of the present invention should not be construed as being limited by these examples. In the following examples, specific compounds are exemplified. However, it is apparent to those skilled in the art that equivalents of these compounds can be used in similar amounts.

From the results of Tables 7 and 8, it was confirmed that a minute current flows by adding two or more kinds of materials having different electrochemical potentials applied to the adhesive layer of the taping sheet according to the present invention.

In addition, it was confirmed that, due to the flow of minute current due to the substance, the pain of the tester with back pain was effectively reduced as in the result of Experimental Example 3.

Experimental Example  6: Adhesion test

The adhesive strength of the adhesive layer of the taping sheet (sample 3, sample 7) prepared in the above example was evaluated after 3 days from each test. The results are shown in Table 9 below. Good adhesion was judged to be poor when the adhesive was adhered without falling off even if it came in contact with moisture or external substances for 3 days during wearing.

Adhesive strength Adhesion loss Sample 3 15 men 12 people 3 people 30 women 25 people 5 people Sample 7 * 15 men 5 people 10 people 30 women 8 people 22 people

The results shown in Table 9 indicate that when the application amount of the adhesive layer of the taping sheet is large, the adhesive strength is excellent, but also the substance having a different electrochemical potential is over-applied per unit area, so that the adhesive strength is lowered.

Therefore, it can be confirmed that an adequate adhesive force is exhibited during the wearing period while exhibiting an effect as a taping sheet in the production of a taping sheet, and appropriate measures not causing skin troubles are required.
