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 muscle strains.
In particular, the present invention relates to a taping device applied to the shoulder region of the 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. Therefore, a taping tool was recently proposed that allows even the general public to easily perform taping techniques on the foot (Japanese Patent Application Laid-Open Nos. 57-66777 and 58-155879).
issue). These taping tools are formed by cutting a sheet material that has an adhesive layer on one surface into a specific shape corresponding to the foot part, and by applying the adhesive layer to the foot part and pasting the taping tool. , which fixes the foot part. However, conventional taping tools can only be applied to specific parts such as the feet, and there are no taping tools that can be applied to other body parts. Moreover, the conventional taping techniques are only designed to realize simple taping techniques with their innovative shapes, so the taping performance is not sufficient, especially for fixing and tightening the affected area, which is necessary for taping techniques. Because of its poor protective effect, it was unable to adequately protect the area affected by the injury, and it also had problems such as being easily peeled off when force was applied to the area to which it was applied.

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 new methods and optimizing the elasticity of the sheet material and the adhesive strength of the adhesive layer, we have developed a new method that allows taping to be performed easily on the shoulder area and provides sufficient taping performance. The purpose of the present invention is to provide a shoulder taping tool.

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 a shoulder portion (indicated by a chain line in the figure). This taping tool has a structure to be applied to the entire surface of the skin, and has fastening pieces 2 and 3 that project straight to both sides at the upper and lower ends of the supporting piece 1, and winding fixing pieces 4 and 5. Along with forming a series,
Circular constrictions 6, 7 are formed between the upper and lower fixing pieces 2, 4, 3, 5. The support piece 1 has an upper edge 10 and a lower edge 11 parallel to each other and is horizontal, with the center of the upper edge 10 positioned above the clavicle, and the entire length of the support piece 1 aligned with the slope of the shoulder. When the waist is bent, the upper portion of the waist portions 6 and 7 corresponds to the shoulder portion, and the lower portion corresponds to the upper arm portion. Furthermore, the constrictions 6, 7
is formed with a curvature and depth that corresponds to the shapes of the shoulders and arms and completely avoids the front and rear areas of the armpits, so that the vertical movement of the arms is not inhibited at all. One of the fastening pieces 2 and 3 is fastened to the upper part of the breast on the chest, and the other is fastened to the shoulder blade on the back. The lower edges 21 and 31 of each stopper and fixing piece 2 and 3 have a smooth curve and are continuous with the constricted portions 6 and 7, and this curve has a shape that follows the roundness of the arm. The winding and fixing pieces 4 and 5 are wound around the upper arm and fastened and fixed with their tips facing each other at a position below the armpit. In this way, the upper and lower edges 10 and 11 of the support piece 1 are made horizontal, and the fixing pieces 2 and 3 and the winding fixing pieces 4 and 5 are provided on both sides of the upper and lower ends, and the constricted parts 6 and 7 are provided between them. By forming this, the entire taping tool perfectly adapts to the shape and irregularities of the shoulder and upper arm.

The taping tool of the above shape is used to fix the ligaments and muscles in the shoulder area and restrict their movement, so the elasticity in the vertical direction (indicated by arrow a) must be less than 50%. be regulated as such. In addition, in the orthogonal lateral direction (indicated by arrow b), it is preferable to have elasticity, and the elasticity should be set to 50% or more.This strengthens the fixation force on the shoulder or upper arm, and It has remarkable effects such as being able to adapt to the movements of people.

FIG. 2 shows a cross-sectional structure of the above-mentioned taping tool, in which an adhesive layer 80 is formed on one surface of the tape base material 8, and a release material 9 is pasted on this adhesive layer 80. As the sheet base material 8, 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 fabric, raw materials include natural fibers such as silk and wool, artificial fibers such as cotton wool and viscose, synthetic fibers such as nylon, Tetron, acrylic, and urethane, or mixed fibers thereof. The strength is required to be 15 kg/2.5 cm or more, more preferably 30 kg/2.5 cm or more (strength is measured according to the Japanese Industrial Standards textile tensile test method). To form the adhesive layer 80, either an acrylic adhesive or a rubber adhesive, or a mixture thereof is used. In the case of acrylic adhesives, the main component thereof is generally an acrylic acid alkyl ester having an alkyl group having 4 to 8 carbon atoms. - 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. In addition, using highly reactive curing agents such as isocyanate-based, epoxy-based, and urea-based, or methods of curing by irradiating with ionizing radiation such as X-rays, γ-rays, and electron beams,
It is also possible to balance the adhesive components. On the other hand, in the case of rubber adhesives, NR, SBR,
Examples include elastomers such as SIS, SBS, IR, and IIR, and for additional adhesive strength, rosin, rosin-modified resins, polyterpene resins, aliphatic aromatic petroleum resins, phenolic resins, coumaron indene resins, and xylene. In addition, in order to maintain the adhesive base in a well-balanced manner, we use petroleum-based plasticizers such as liquid paraffin and polybutene, and vegetable-based 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 parts by weight of tackifier per 100 parts by weight of elastomer.
~300 parts by weight, preferably 50 to 250 parts by weight, more preferably 110 to 200 parts by weight. If the amount of the tackifier exceeds 300 parts by weight, the elastic properties of the elastomer will be significantly reduced, causing severe pain when peeled 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 80 may contain medicinal ingredients such as skin stimulants 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 drug. In addition, transdermal absorption enhancers, stabilizers, fragrances, mineral oil,
A keratin emollient, an antihistamine, etc. may be added as appropriate.

Further, as for the release material 9, paper such as kraft paper, Krashin paper, parchment paper, etc., which has been subjected to release treatment such as silicone coating, polyethylene, polypropylene, polyester, polyvinyl chloride, etc.
A plastic film such as polyvinylidene chloride, polystyrene, or cellophane is 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 methacrylic acid, and 2% by weight of benzoyl peroxide at 50 to 70°C.

% by weight, 48% by weight of rosin modified resin, 18% by weight of liquid paraffin, 5% by weight of titanium oxide, 3% by weight of l-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 melt 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 thereon as a release material.

With the release material 9 removed and the adhesive layer 80 exposed, the support piece 1 is applied to the area from the shoulder to the upper arm that is to be treated or prevented. In this case, first, the winding fixing pieces 4 and 5 are wrapped around the upper arm and fixed, and then the upper arm is lifted and suspended, and the supporting piece 1 is attached, and each of the fixing pieces 2, 3 is fixed on the chest and back. The above winding fixing pieces 4, 5 and stop fixing pieces 2,
3 is for fixing it to a predetermined location while stretching it to both sides, without causing any sagging or wrinkles. Incidentally, in the above-mentioned installation, a conventionally known patch or poultice may be applied to the affected area, and the taping tool of the present invention may be applied thereon.
When the taping tools are attached to both shoulders in the above procedure, according to the shape of the present invention, as shown in FIGS. It is positioned correctly on the joint, and the whole part perfectly conforms to the shape of the shoulder part, and there are no wrinkles or sagging, especially at the ends.

In this attached state, the supporting piece 1 is restricted from expanding and contracting in the vertical direction, so it serves to fix the ligaments and muscles, that is, it restricts the ligaments from stretching in the vertical direction. In addition, since the entire body fits the shoulder area without sagging, a force that restricts movement acts in the torsional direction as well. Furthermore, on the one hand, since the constrictions 6 and 7 are located corresponding to the proximal end of the upper arm,
The vertical movement of the arm is not hindered in any way. 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 shoulder area, and by optimizing the elasticity of the sheet material and the adhesive strength of the adhesive layer. By simply pasting it from the shoulder to the upper arm, ordinary people can easily apply the taping technique to the shoulder area. Moreover, since the entire body conforms to the shoulder area and fixes the muscles and ligaments in the shoulder area, their movement can be effectively and moderately restricted, and in addition, even if force is applied to the attachment part, the adhesive layer will not easily adhere to the shoulder area. It does not peel off and can reliably protect and prevent injuries in the shoulder area.

In addition, since the overall shape is simple, when it is industrially produced, there is no wastage of materials, it is easy to handle, and it has many remarkable effects such as reducing manufacturing costs.
