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 knee 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 can moderately restrict the movement of the affected area, and the degree of restriction can be
It has the advantage of being able to 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, recently, a taping tool was proposed that allows even the general public to perform taping techniques on the foot easily (Japanese Patent Laid-Open Nos. 57-66777 and 155879-1988). 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 limbs, particularly ankles and soles, 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 a new technique 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 techniques to be easily applied to the knee area and provides sufficient taping performance. The purpose of the present invention is to provide a knee taping tool.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

1 and 6 show the taping tool of the present invention applied to the knee region (indicated by a dashed line in the figures). This taping tool has a structure that is applied to the entire surface of the skin, and constrictions 2 and 3 are provided at the center of both side edges of a supporting piece 1, and an upper half 10 and a lower half 1
1, and the lower half 11 is formed with a series of retaining pieces 4 projecting in the shape of a knob toward one side. The upper half 10 is located corresponding to the front or side surface of the thigh, and the upper edge 12 is formed in an oblique straight line shape.The lower half 11 is located corresponding to the front or side surface of the lower leg, and the lower end The edge 13 is formed into a round shape projecting downward. One of the constricted portions 2 located between the two has a smoothly curved shape to match the contour of the patella, and the other constricted portion 3 has an acute angle due to the protrusion of the fixing piece 4. Fixing piece 4
is fixed at a position below the knee joint, and its upper edge 41 is a horizontal straight line, and its lower edge 42 is a gentle curve.
It is continuous with the protruding base end of No.3. Note that the shape may be symmetrical to the shape shown in FIG. 1 depending on whether it is applied to the right foot or left foot, and whether it is applied to the inside or outside of the knee.

The taping tool of the above shape is used to protect the knee joint and to fix the collateral ligaments of the knee and limit their movement, so the elasticity in the vertical direction (indicated by arrow a) is The ratio is regulated to be below 50%. If the expansion/contraction rate is set to this level, it will be possible to sufficiently adapt to the bending of the knee. 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. 2 shows a cross-sectional structure of the above taping tool, in which an adhesive layer 6 is formed on one surface of a tape base material 5, and a release material 7 is pasted on this adhesive layer 6.
As the sheet base material 5, a strong sheet material such as cloth, nonwoven fabric, paper, synthetic resin membrane, foam, etc. is adopted, and cloth or nonwoven fabric is preferably 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 5 must be 15 kg/2.5 cm or more, more preferably 30 kg/2.5 cm or more (strength is determined by Nippon Kogyo). Measured according to the standard textile tensile test method).
To form the adhesive layer 6, 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, hydroxy It is produced by copolymerizing alkyl acrylate with a monomer having a specific functional group. Among these, alkyl acrylate must be blended in an amount of 50% by weight or more based on the total weight, and 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 SBS, IR, and IIR, and to further impart adhesive strength, rosin, rosin-modified resin, polyterpene resin, aliphatic aromatic petroleum resin, phenol resin, coumaron indene resin, 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 tackifier
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.
The shear adhesive strength is 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, the 180° peel adhesive strength is 200g/18mm.
If it is smaller, or if 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 6 may contain medicinal ingredients such as skin stimulants and anti-inflammatory analgesics, if necessary.

For example, as a medicinal ingredient, methyl salicylate,
Glycol salicylate, salicylic acid, menthol, peppermint oil, camphor, thymol, acrinol, rhoto extract, chlorpheniramine maleate, diphenhydramine, nicotinic acid benzyl ester, capsicum extract, nonylic acid vanillylamide, capsaicin, ibuprofen, indomethacin, alkali Rofuenatsk, Ketoprofen,
One or two of flobiprofen, fenoprofen, naproxen, piroxicam, acemetacin, clidanaruc, loxoprofen, esters thereof, corticosteroids, etc.
Select and use more than one species. The appropriate amount of these medicinal ingredients is 0.01 to 20 parts by weight per 100 parts by weight of the drug. Further, transdermal absorption enhancers, stabilizers, perfumes, mineral oils, keratin softeners, antihistamines, etc. may be appropriately added.

Furthermore, the release material 7 may be paper such as kraft paper, glassine paper, or parchment paper that has been subjected to a release treatment such as silicone coating, or a plastic film such as polyethylene, polypropylene, polyester, polyvinylidene chloride, polyvinyl chloride, or polystyrene. , cellophane are selected and used. Incidentally, 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.

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
% 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 7 removed and the adhesive layer 6 exposed, the support piece 1 is attached to the front or side surface of the knee to be treated or prevented. In this case, the waist part 2
Following the contour of the patella, place the upper half 10 on the thigh and the lower half 11 on the lower leg, and then pull the upper half 10 and the lower half 11 in direction b. At the same time, the fixing piece 4 is fastened and fixed to the back of the knee at a position below the knee joint. 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 from thereon. Further, in order to prevent damage due to strong impact along the constricted portion 2, it is more preferable to provide reinforcement by providing a patch cloth or the like.

When the taping tool is attached according to the above procedure, according to the shape of the present invention, as shown in FIGS. 3 to 5, the support piece 1 is correctly positioned from the front side of the knee to the side, and the entire support piece 1 conforms to the shape of the knee part. It fits perfectly, with no wrinkles or sagging, especially at the edges.

In this 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, restricts the ligament from stretching, and protects the knee joint. Furthermore, the present invention has a shape that combines an X support and a vertical support using a taping technique, and is consistent with taping logic.

As mentioned above, the present invention was developed by devising the shape of the sheet material to be optimal for applying taping to the knee area, and by optimizing the elasticity of the sheet material and the adhesive strength of the adhesive layer. By simply pasting the tape between the knees and extending from the thighs to the lower legs, ordinary people and the public can easily apply the taping technique to the knees. Furthermore, since the entire body conforms to the knee area and fixes the knee ligaments, their movement can be effectively and moderately restricted, and the adhesive layer does not peel off easily even if force is applied to the applied part. Therefore, injuries to the knee joint can be reliably protected and prevented.

In addition, since it has a simple overall shape, when it is industrially produced, there is no wastage of materials, it is easy to manufacture and handle, and it has many excellent effects such as reducing product cost.
