Description

[Detailed description of the invention] The present invention relates to a taping tool used to treat or prevent disorders of bones, muscles, joints, etc. such as bruises, sprains, dislocations, fractures, and dislocations. The invention relates to a taping device applied to the ankle region of a human body.

Conventionally, in order to treat or prevent this type of disorder, it is common practice to attach protective equipment such as a cast or a supporter to the affected area. For example, a cast has a structure that completely fixes the affected area, so it is effective in treating severe injuries such as bone fractures, but it is not suitable for treating moderate to mild injuries that allow moderate exercise. In addition, in the case of a supporter, it can be expected to have the effect of suppressing internal bleeding or swelling by compressing the injured area, but it does not have the effect of regulating the movement of the injured area and completely lacks the function of protecting the injured area. Therefore, in recent years, a technique called taping, in which adhesive tape is pasted or wrapped around the affected area, has attracted attention. This taping technique has the advantage that the movement of the affected area can be moderately controlled, and the degree of regulation can be adjusted as appropriate depending on the type and symptoms of the disorder. However, since this taping technique requires the acquisition of specialized and skilled skills, it has been difficult for ordinary people to use this taping technique. Under these circumstances, a taping tool for easily performing the taping technique on the ankle was recently proposed (Utility Model Application Publication No. 125372/1983). However, since this taping tool has a structure that severely restricts the movement of the ankle region, it is not suitable for use in the treatment or prevention of moderate to mild disorders that allow moderate exercise. In addition, since the overall shape is extremely complex, when it is industrially produced, materials tend to be wasted, resulting in high costs and inconvenience in handling. Moreover, because the conventional products aim only at realizing a simple taping technique with their innovative shape, the taping performance is not sufficient, especially the effect of fixing the affected area necessary for the taping technique. Due to the lack of adhesive, it was not possible to sufficiently protect the area affected by the disorder, and in addition, there were problems such as easy peeling when force was applied to the adhesive area.

This invention focuses on the fact that the performance of taping is affected not only by the shape but also by the elasticity of the sheet material and the adhesive strength of the adhesive layer. By devising the shape and optimizing the elasticity of the sheet material and the adhesive strength of the adhesive layer, taping techniques can be easily applied to the ankle area and sufficient taping performance can be obtained. The purpose of the present invention is to provide a novel ankle taping device.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 shows the taping tool of the present invention applied to the ankle region (indicated by a chain line in the figure). This taping tool has a structure that is applied to the entire surface of the skin, and includes a supporting piece 1 having a fixing part 10 at its lower end, and a pair of winding fixing parts that project diagonally upward on both sides of the upper end of the supporting piece 1. Pieces 2 and 3 are formed in series.

The support piece 1 has a longitudinally long shape corresponding to the outer or inner surface of the ankle, and when the ankle is positioned approximately at the center of the support piece 1, its upper edge 11 extends 1 cm from the gastrocnemius muscle. The stop and fixing part 10 at the lower end goes around the sole of the foot and is fixedly fixed to the sole of the foot.

Each of the winding and fixing pieces 2 and 3 is fixedly fixed by wrapping it around the ankle,
The lower edges 21, 31 of each winding fixing piece 2, 3 form an obtuse angle θ with respect to each side edge 12, 13 of the support piece 1, and the lower edges 21, 31 and the side edges 12, 13 are arc-shaped portions, respectively. 4 and 5. By oriented the winding fixing pieces 2 and 3 diagonally upward and providing the arcuate portions 4 and 5 in this manner, the entire taping tool perfectly fits the ankle portion. Also, the winding fixing piece 2,
3 has side edges 22, 32 facing diagonally inward, and upper edges 33, 34 are in the same horizontal line as the upper edge 11 of the supporting piece 1.

FIGS. 2 to 4 show other modifications. In the embodiment shown in FIG. 2, the degree of protrusion of each winding fixing piece 2, 3 is set small to simplify the shape and save material. Further, in the embodiment shown in FIG. 3, a protrusion 14 is provided at the upper end of the support piece 1 to increase the overall length of the support piece 1, thereby strengthening the fixing function. Furthermore, in the example shown in FIG. 4, the upper edge 11 of the support piece 1 is formed in a V-shape to save material.

The taping device of the above shape is used to fix the lateral or medial ligament of the ankle and restrict its movement, and therefore the elasticity in the vertical direction (indicated by arrow a) is 50% or less. It is regulated to be. In addition, in the orthogonal lateral direction (indicated by arrow b), it is preferable to have elasticity, and the elasticity should be set at a rate of 50% or more. It has remarkable effects such as being able to adapt to the environment.

FIG. 5 shows a cross-sectional structure of the above taping tool, in which an adhesive layer 7 is formed on one surface of a tape base material 6, and a release material 8 is pasted on this adhesive layer 7.
As the sheet base material 6, a strong sheet material such as cloth, nonwoven fabric, paper, synthetic resin film, foam, etc. is adopted, and preferably cloth or nonwoven fabric is used, and cloth is particularly preferably used. In the case of fabrics, the raw materials include natural fibers such as silk and wool, artificial fibers such as cotton wool and viscose, nylon,
Synthetic fibers such as Tetron, acrylic, urethane, or mixed fibers thereof are used, and the strength of the sheet base material 6 must be 15 kg/2.5 cm or more, more preferably 30 kg/2.5 cm or more (strength is determined by Nihon Kogyo). Measured according to the standard textile tensile test method).
To form the adhesive layer 7, either an acrylic adhesive or a rubber adhesive or a mixture thereof is used. In the case of acrylic adhesive,
The main component of this generally has 4 carbon atoms.
Examples include acrylic acid alkyl esters having ~8 alkyl groups, and these acrylic acid alkyl esters include butyl acrylate, acrylic acid n
- alkyl acrylates such as octyl and 2-ethylhexyl acrylate, monomers with high glass transition points such as vinyl acetate, methyl acrylate, and methyl methacrylate, and acrylic acid, methacrylic acid, acrylamide, N-substituted acrylamide, It is produced by copolymerizing with a monomer having a functional group such as hydroxyalkyl acrylate. Of these, alkyl acrylate must be blended in an amount of 50% by weight or more based on the total weight; if it is less than 50% by weight, sufficient adhesive strength will not be obtained. The balance of the adhesive components can be adjusted using a highly reactive curing agent such as isocyanate, epoxy, or urea, or by curing by irradiating ionizing radiation such as X-rays, γ-rays, or electron beams. It is also possible to take On the other hand, in the case of rubber adhesives, NR, SBR, SIS,
Examples include elastomers such as SNS, IR, and IIR, and for additional adhesive strength, rosin, rosin-modified resin, polyterpene resin, aliphatic aromatic petroleum resin, phenol resin, coumaron indene resin, and xylene resin. , a tackifier such as styrene resin, and in order to maintain the adhesive base in a well-balanced manner, petroleum plasticizers such as liquid paraffin and polybutene, vegetable plasticizers such as soybean oil, sesame oil, olive oil, and camellia oil, Fillers such as zinc oxide, titanium oxide, calcium carbonate, white carbon, and kaolin may be appropriately blended. Furthermore, crosslinking treatment may be performed by adding sulfur, peroxide, etc., or irradiating with ionizing radiation such as X-rays, γ-rays, and electron beams. An inhibitor may also be added. The amount of these compounds is 25 to 300 parts by weight of tackifier per 100 parts by weight of elastomer.
The amount is preferably 50 to 250 parts by weight, more preferably 110 to 200 parts by weight. In addition, the adhesive agent
If it exceeds 300 parts by weight, the elastic properties of the elastomer will be significantly reduced, causing severe pain when peeled off from the skin surface, or leaving adhesive components on the skin.

Thus, the adhesive strength of the taping tool is expressed as the 180° peel adhesive strength to the phenolic resin plate.
Set to 200g/18mm or more, preferably 400g/18mm, more preferably 600g/18mm or more, and the shear adhesive strength is 2Kg/18mm or more, preferably 5
Kg/18mm or more, more preferably 10Kg/18mm or more. In addition, if the 180° peel adhesive force is less than 200 g/18 mm or the shear adhesive force is less than 2 kg/18 mm, the fixation of the taping tool to the skin becomes weak and it becomes easy to peel off.

The adhesive layer 7 may contain medicinal ingredients such as skin irritants and anti-inflammatory analgesics, if necessary.
For example, medicinal ingredients include methyl salicylate, glycol salicylate, salicylic acid, menthol, peppermint oil, camphor, thymol, acrinol, rhoto extract, chlorpheniramine maleate, diphenhydramine, benzyl nicotinic acid ester, capsicum extract, vanillyl nonylic acid. , capsaicin, ibuprofen, indomethacin, alklofenac, ketoprofen, flobiprofen, fenoprofen, naproxen, piroxicam, acemetacin, clidanuc, loxoprofen and esters thereof, corticosteroids, etc. Select and use. The appropriate amount of these medicinal ingredients is 0.01 to 20 parts by weight per 100 parts by weight of the base. Furthermore, as medicinal ingredients, transdermal absorption enhancers, stabilizers, fragrances, mineral oils, skin irritants, keratin emollients, antihistamines, etc. may be added as appropriate.

Furthermore, as for the release material 8, paper such as kraft paper, Krashin paper, parchment paper, etc. that has been subjected to release treatment such as silicone coating, plastic film such as polyethylene, polypropylene, polyester, polyvinylidene chloride, polyvinyl chloride, polystyrene, etc. , cellophane are selected and used.

Note that a large number of ventilation holes may be provided on the entire surface of the taping tool, which has the effect of preventing dermatitis such as skin irritation and preventing sweat from accumulating and peeling off.

Next, specific examples of the composition are as follows.

[Example 1] Acrylic adhesive obtained by copolymerizing 72% by weight of 2-ethylhexyl acrylate, 23% by weight of vinyl acetate, 3% by weight of metal acrylic acid, and 2% by weight of benzoyl peroxide at 50 to 70°C. The agent was dissolved in a toluene solvent to a solid content concentration of 25%, and this solution was applied to a polyurethane woven fabric with a thickness of 200μ (wet) having a stretching ratio of 133% in the orthogonal direction and a stretching ratio of 30% in the vertical direction. It was spread and passed through a drying oven (80 to 120°C) to form an adhesive layer, on which silicone-coated kraft paper was pasted as a release material.

[Example 2] Acrylic adhesive obtained by copolymerizing 68.42 parts of 2-ethylhexyl acrylate, 21.05 parts of vinyl acetate, and 10.53 parts of N-tert-butylacrylamide at 50 to 70°C, 95% by weight of -menthol. 3% by weight and 2% by weight of glycol salicylate were dissolved in a toluene solvent to a solid concentration of 30%, and this solution was spread on the same fabric as in Example 1 under the same method conditions to form an adhesive layer. .

[Example 3] NR (natural rubber) 33% by weight, polyterpene resin
33% by weight of liquid isoprene rubber, 16% by weight of liquid isoprene rubber, and 18% by weight of zinc oxide were mixed and dispersed uniformly using a kneader, and then spread on the same fabric as in Example 1 to a thickness of 50 μm using a calendar roll at a temperature of 70 to 90°C. An adhesive layer was formed, and kraft paper coated with silicone was pasted thereon as a release material.

[Example 4] NR (natural rubber) 30% by weight, rosin modified resin 27
% by weight, 15% by weight of polybutene, 23% by weight of zinc oxide, 3% by weight of menthol, and 2% by weight of methyl salicylate were mixed and dispersed uniformly in a kneader, and then the temperature
An adhesive layer was formed by rolling the same fabric as in Example 1 to a thickness of 50 μm using a calender roll at 70 to 90° C., and kraft paper coated with silicone was pasted thereon as a release material.

[Example 5] SIS (Styrene-Isoprene-Styrene rubber: Ciel Chemical Co., Ltd. CARIFLEX TR-1107) 24
48% by weight of rosin-modified resin, 18% by weight of liquid paraffin, 5% by weight of titanium oxide, 3% by weight of -menthol, and 2% by weight of glycol salicylate were melted and mixed uniformly in a mixer at a temperature of 120 to 160°C. The liquid was spread on the same fabric as in Example 1 to a thickness of 50 μm using a reverse roll coater to form an adhesive layer, and kraft paper coated with silicone was pasted onto the adhesive layer as a release material.

With the release material 8 removed and the adhesive layer 7 exposed, the supporting piece 1 is attached to the outer or inner surface of the ankle that is to be treated or prevented. In this case, the approximate center of the support piece 1 is placed around the ankle, and the upper edge 11
After positioning each of them 10 to 25 cm above the ankle, while stretching the winding fixing pieces 2 and 3,
Wrap it around your ankle and secure it. Next, support piece 1
is attached to the side surface of the ankle so as not to sag, and finally the lower end of the fixing part 10 is passed around to the sole of the foot to fix it.

Another method of attachment is to first wrap the lower end fixing part 10 around the sole of the foot to secure it in place, then pull the support piece 1 to lift the foot, positioning the approximate center part at the ankle and attaching it. Finally, there is a method of tightening and stretching the winding fixing pieces 2 and 3 and wrapping them around the ankle to fix the ankle.

In addition, in the case of said attachment, a conventionally known patch or poultice may be applied to the affected area, and the taping tool of the present invention may be attached thereon.

When the taping tool is attached in the above procedure, according to the shape of the present invention, as shown in FIGS. 6 to 8, the support piece 1 is correctly positioned on the lateral or medial ligament, and the entire support piece 1 is placed on the ankle area. It perfectly conforms to the shape, with no wrinkles or sagging, especially at the edges.

In such an attached state, the support piece 1 is restricted from expanding and contracting in the vertical direction, so it functions to fix the ligament, that is, it restricts the ligament from stretching in the vertical direction (indicated by arrow A). In addition, since the entire body is adapted to the ankle portion without sagging, a force to restrict movement is exerted in the bending direction (indicated by arrow B) and the torsional direction (indicated by arrow C). Furthermore, support piece 1
Since the lower end of the Achilles tendon is located between the tape and one of the winding fixing pieces 2, that is, at the outer side of the arcuate portion 4, it is possible to prevent the Achilles tendon from being compressed by the taping tool. Further, the shape of the winding and fixing pieces 2 and 3 is designed so that they do not completely cover the ankle in order to prevent blood circulation disorder and congestion of the ankle. Furthermore, the present invention has a shape that combines an X support and a vertical support using the taping technique, and is consistent with the taping theory.

As mentioned above, the present invention was developed by devising the shape of the sheet material to be optimal for applying taping to the ankle area, and by setting the elasticity of the sheet material and the adhesive strength of the adhesive layer to the optimal state. By simply pasting it on the outer or inner surface of the ankle, ordinary people and people can easily apply the taping technique to the ankle. Moreover, since the entire part conforms to the ankle area and fixes the muscles and ligaments in the ankle area, their movement can be effectively and moderately restricted, and in addition, even if force is applied to the attachment part, the adhesive layer easily It does not peel off and can reliably protect and prevent injuries in the ankle area.

In addition, since the overall shape is a simple Y- or T-shape, when industrially producing it, there is no wastage of materials, it is easy to handle, and manufacturing costs can be reduced. be effective.
