Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an adhesive tape for fixing a knee joint. More particularly, the present invention relates to an adhesive tape for fixing a knee joint, which can be applied to a knee joint and fixed to reduce pain in a joint caused by aging or exercise.

[0002]

[Prior art]

 Conventionally, many people have suffered from pain occurring in joints such as knees, elbows, and wrists. Since the joints are deeply involved in human movement, daily pain often becomes difficult when pain occurs in this area. In particular, serious problems occur not only physically but also mentally, for example, the knee joint becomes bedridden due to walking disorders. There are many causes for such joint pain, one of which is deformation and wear of articular cartilage. Involved in the progression of articular cartilage deformation and wear are age-related loss of muscle strength around the joints, overuse, and obesity, which particularly affect the knee joint, which is heavily weight-bearing. As described above, pain in the knee joint is a serious problem, and as is evident from the recent aging society, excessive exercise due to health consciousness, and an increase in obese people due to changes in diet, The population with pain is on the rise, and the number of disability complaining of joint pain is increasing.

[0003] As a method of reducing the pain of such joints, there are painkillers, drugs such as muscle relaxants and drug treatments such as local injections, and physiotherapy for inflammation and analgesia using lasers, interference waves, microwaves and the like. In addition, there are various methods such as surgical treatments such as osteotomy and total joint replacement, and one of them is a method of fixing joints to reduce pain. This method of fixing the joint uses a dedicated adhesive tape that can be easily obtained at a pharmacy or the like, so that it is relatively inexpensive and simpler than other methods such as drug treatment, hospital visit, and surgery. It is an effective means of reducing joint pain. In addition, the method of wrapping adhesive tape around joints and ligaments to support, reinforce, and compress the relevant parts also plays a significant role in preventing disabilities and providing emergency treatment during sports. (Hereinafter, the method of fixing joints with adhesive tape is defined as taping.) However, most people do not have specialized knowledge of taping, and even if they have acquired technical knowledge in specialized books, etc. It is difficult for them to master the training, so they are currently going to osteopaths for taping by specialized trainers.

[0004] However, it is time-consuming and troublesome to go to an osteopath, and it is very troublesome for a person who has a joint injury. Even if taping can be performed, a commercially available tape for taping generally has an adhesive treatment on the entire surface, so that there is a sense of incongruity inside the joint that is sensitive to irritation, which is always uncomfortable. In addition, since the adhesive layer is in close contact with the inner part of the joint where a lot of spontaneous sweating occurs, there is a problem that the skin surface at this part becomes stuffy and skin irritation occurs.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned problems in the conventional adhesive tape, and is easy to operate even for a person who does not have expertise in taping. An object of the present invention is to provide an adhesive tape for fixing a knee joint, which can reduce skin irritation due to stuffiness.

[0006]

[Means for Solving the Problems]

 Therefore, the present inventors have conducted intensive studies in order to achieve the above-mentioned object, and as a result, by making a cut in a specific portion of the adhesive tape having a predetermined size in advance, even a person who does not have specialized knowledge can make it. Taping can be easily performed, and by providing a weak adhesive or non-adhesive part with adhesive partially applied to the inner part of the joint, uncomfortable feeling due to bending and stretching motion after sticking adhesive tape and natural feeling They found that the stuffiness caused by perspiration could be reduced satisfactorily, and completed the present invention.

That is, the adhesive tape for fixing a knee joint according to the first invention of the present application has a rectangular portion having a long side having a length of 35 to 55 cm and a short side having a length of 5 to 15 cm. Both are pressure-sensitive adhesive tapes having a pressure-sensitive adhesive layer on one side of a support that expands and contracts in the longitudinal direction. The pressure-sensitive adhesive tape has a weakly-adhesive part partially coated with a pressure-sensitive adhesive on at least a part of the pressure-sensitive adhesive layer. A cut is made from one short side toward the vicinity of the weak adhesive portion.

The adhesive tape for fixing a knee joint according to the second invention of the present application has a rectangular portion having a long side having a length of 35 to 55 cm 2 and a short side having a length of 5 to 15 cm. An adhesive tape comprising an adhesive layer, a non-adhesive part provided in a part of the adhesive layer, and a cut extending from at least one of the short sides to the vicinity of the non-adhesive part. It consists of a tape body having an adhesive layer formed on one side of a support that expands and contracts in the direction, or at least a tape body that has an adhesive layer formed on one side of a support that expands and contracts in the longitudinal direction. Is what you do.

[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a view showing an adhesive tape for fixing a knee joint according to an embodiment of the present invention, which corresponds to the first invention of the present application. The pressure-sensitive adhesive tape for fixing a knee joint is made of a pressure-sensitive adhesive tape having a pressure-sensitive adhesive layer 2 formed on one surface of a support 1. The adhesive tape for fixing a knee joint has a rectangular portion 5 having a long side (length L) and a short side (length W) so as to be wound around the knee joint. The rectangular portion 5 is attached so as to surround the medial and lateral accessory ligaments of the knee joint. The rectangular part 5 has a weak adhesive part 4 at the center. As described later, the weak adhesive portion 4 is partially coated with an adhesive, and is an area applied to the inside of the knee joint.

A cut 3 is formed in the rectangular part 5 from the short side to the vicinity of the weak adhesive part 4. The cut 3 facilitates the sticking of the adhesive tape to the joint, which has been difficult so far, and provides an effect of simplifying taping. There is no particular limitation on the number of cuts 3 or the place where the cuts are made, as long as the cuts are made from the short side to the weakly adhesive portion 4 so that anyone can easily tap. However, as shown in FIG. It is preferable to apply one by one from the center of the short side. The cut 3 is made long enough to be wound around the knee joint from the inside to the outside.

The rectangular portion 5 is wound around the knee joint and substantially fixes the joint as described later, and has a long side of 35 to 55 cm, preferably 40 to 50 cm. If it is shorter than 35 cm, it may not be able to wrap around the knee joint sufficiently. On the other hand, if the length is longer than 55 cm, the handling becomes poor, and the adhesive tape portion 7 divided by the cut 3 re-enters the inside of the knee joint, and the possibility that bending and stretching of the knee is restricted increases. The short side is 5 to 15 cm, preferably 7 to 10 cm. If the length is shorter than 5 cm, the patella cannot be sufficiently enclosed. If the length is longer than 15 cm, the patella will also be surrounded at a position distant from the patella, and the fixation of the joint region will be reduced.

The support 1 supports the pressure-sensitive adhesive layer 2 (and the weakly-adhesive portion 4) on one side, and fixes the joint by an appropriate degree of elongation, and imparts an effect of reducing pain. is there. The support 1 preferably has an adhesive tape having an elongation of 30% or more in the longitudinal direction in order to impart followability and fixability to the knee joint. The upper limit of the degree of elongation of the support 1 is preferably about 110%, and more preferably 40 to 80% from the viewpoint of the fixation of the joint. Further, in the present invention, the tensile strength in the longitudinal direction of the support 1 is 10 N / 19 mm width or more, preferably 200 N / 19 mm width or less, and the 20% modulus is 0.5 to 8 N / 19 mm width. Are preferred. If the elongation rate is large, there is a fear that it may be stretched out by repeated bending in a region applied to the inside of the knee joint, which is not preferable. As a material of such a support 1, a natural rubber sheet having elasticity, a synthetic rubber sheet, a warp-stretch cloth using a stretchable yarn as a warp (for example, a stretchable yarn using urethane as a yarn core is used. Spandix woven fabric), stretchable fabric using stretchable yarns for warp and weft, strong twisted fabric in which strong twisted yarn is driven in the longitudinal direction, knitted fabric that expands and contracts in all directions, laminating these woven fabrics with polyurethane, etc. Can be used, but it has good stretchability and strength under the above conditions, as it can exert the effects such as followability, fixability, and compression (kickback) which are important for the adhesive tape for taping. It is preferable to use a strong twist cloth. The thickness of the support 1 is appropriately determined depending on the site to be used and the characteristics of the support 1, but is preferably 50 to 400 g / m ² in consideration of the ability to follow the skin, and more preferably 100 to 400 g / m ^2. 200 g / m ² is more preferred.

The adhesive tape for fixing the knee joint has a tongue 6 having a non-rectangular adhesive property at an end of the adhesive tape 7 divided by the cut 3. The tongue 6 improves the visibility of the end of the adhesive tape 7, and the end of the adhesive tape 7 wound from the tongue 6 is located with a finger pad, and the end of the tongue 6 is easily seen therefrom. Can be peeled off. The tongue 6 does not contribute much to the fixation of the knee joint, and its shape is non-rectangular from the viewpoint of visibility and curling up. If it is non-rectangular, it is not particularly limited. . For example, a semicircle or semi-ellipse as shown in FIG. 1 and a substantially triangular shape as shown in FIG. The tongue 6 is preferably provided at each end of each of the adhesive tape portions 7 divided by the cuts 3 as shown in FIG. 1, but as shown in FIG. After the two semicircular, semielliptical, and substantially triangular extensions are provided, a cut 3 may be made from the extension. In addition, if the end of the adhesive tape portion 7 having the tongue portion 6 and divided is formed in a non-rectangular shape, the adhesive tape portion 7 is less likely to be peeled off than when left in a rectangular shape. It is particularly effective in the case of a knee joint having a large amount of flexion and extension. The tongue 6 is optionally provided. Accordingly, the adhesive tape for fixing the knee joint can be constituted only by the rectangular portion 5, and as shown in FIG. 4, the adhesive tape may be formed of the long side and the short side within the above range. The tongue 6 may be provided on both the left and right adhesive tape portions 7 or on either one of the left and right sides.

On the other hand, the pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 2 formed on one surface of the support 1 may be any of various well-known or practical ones in the field of general tapes for taping. Can be used. Specifically, an acrylic adhesive, a rubber adhesive, a vinyl ether adhesive, a silicone adhesive, or a gel adhesive can be used, but in consideration of skin irritation, etc., an acrylic adhesive or gel adhesive is used. It is preferable to use an agent. Similarly to the thickness of the support 1, the thickness of the pressure-sensitive adhesive layer 2 is conveniently determined depending on the use site of the pressure-sensitive adhesive tape of the present invention, the pressure-sensitive adhesive, and the like, but is preferably 20 to 400 μm, and more preferably 40 to 120 μm. Is more preferred.

With regard to the application of the adhesive, the adhesive is applied to the entire surface of one side of the support 1, but the adhesive is partially applied to the weak adhesive portion 4, for example, a plurality of strips are provided. The weak adhesive portion 4 is provided in a region applied to the inside of the knee joint. In other words, the weak adhesive portion 4 serves as a guide to indicate a sticking position at the time of winding. In addition, the partial coating may have a linear shape, a wavy shape, or other shapes such as partial grid lines as long as a space functioning as an air passage is secured between the adhesive layers. Generally, it is preferable to use a corrugation in which the cross-sectional area of the interstitial space has a small change over time, but it may be appropriately determined according to the characteristics of the adhesive used. The adhesive may be partially applied at least in the weakly adhesive portion 4, but is preferably applied in a strip shape or the like to the entire surface of one side of the support 1. In this case, the spacing between the stripes may be equal, but from the viewpoint of securing a space inside the knee joint, it is preferable that the spacing between the stripes in the weakly adhesive portion 4 be as large as possible. As a result, stuffiness on the skin-adhered portion, especially on the inside of the knee joint, is prevented, and the inside of the knee joint is kept comfortable. The shape of the weak adhesive portion 4 is not limited to a rectangular shape as shown in FIG. 1, but may be a trapezoid, a polygon, an ellipse, or other various shapes. In the adhesive tape for fixing a knee joint in FIGS. 1 to 4, the weak adhesive portion 4 has the same short side length as the shorter side length of the rectangular portion 5, but may be shorter than this. It is.

Furthermore, in order to prevent the surface of the pressure-sensitive adhesive layer 2 from being contaminated, it is preferable that the surface of the pressure-sensitive adhesive layer 2 be covered with a separator (not shown) until use. As the separator, those generally used for adhesive tapes and sheets to be stuck to the skin are used. Specifically, high-quality paper, glassine paper, parchment paper, etc., polyethylene-laminated surface coated with a release agent such as silicone resin with release performance, or high-quality paper anchor coated with resin, etc. are used. .

The adhesive tape for fixing the knee joint, as shown in FIG. 5, applies the weak adhesive portion 4 to the inside (rear side) of the knee joint, peels off the separator, and overlaps the adhesive tape portion 7 divided by the cut 3. As shown in FIG. 6, it is wound around the patella of the knee joint. Since the joint is worn in this way, good fixation of the joint is obtained, so that pain can be reduced. In addition, since the cut 3 is provided, the appropriate position and method of attachment are clarified, so that anyone can easily perform taping.

The cut 3 is preferably formed on both of the two short sides, but may be formed on only one of the short sides as shown in an adhesive tape shown in FIG. In this case, the weak adhesive portion 4 is provided at a position closer to the short side than the center of the rectangular portion 5, and the cut 3 is formed on the short side farther away from the rectangular portion 5. Then, the side where the cut 3 is not formed is first wound around the outside of the knee joint, and then the adhesive tape portion 7 divided by the cut 3 may be wound. Of course, as shown in FIG. 7, a non-rectangular tongue extension 11 may be provided on the short side with no break 3.

FIGS. 8, 9 and 10 are cross-sectional views showing still another embodiment of the adhesive tape for fixing a knee joint according to the present invention, corresponding to the second invention of the present application. These adhesive tapes have a non-adhesive portion 8 applied to the inside of the knee joint. The pressure-sensitive adhesive tape shown in FIG. 8 is formed of one tape body, and is formed by covering the non-adhesive portion 8 with the non-adhesive member 9 on the pressure-sensitive adhesive layer 2. Further, the pressure-sensitive adhesive tape shown in FIG. 9 is formed of one tape body, and is formed by forming the non-pressure-sensitive portion 8 without forming the pressure-sensitive adhesive layer 2. The adhesive tape shown in FIG. 10 is obtained by connecting two tape bodies with a non-adhesive member 9.

Each of the adhesive tapes shown in FIGS. 8 to 10 is different from the adhesive tape according to the first invention only in that a non-adhesive portion 8 is formed in a region applied to the inside of the knee joint. It is. The planar shape can be any of the shapes (outer peripheral shape) shown in FIG. 1A and FIGS. That is, in each of these adhesive tapes, the rectangular part 5 is formed in the size range described above, and the tongue part 6 is provided at the end of the adhesive tape part 7 divided by the cut 3. As the structure of the tape body, a structure in which the pressure-sensitive adhesive layer 2 is provided on one surface of the elastic support 1 as described above is used, and therefore a detailed description thereof is omitted here. Further, in the case where two tapes are connected like an adhesive tape shown in FIG. 10, the rectangular portion 5 means the whole connected by two tapes.

The non-adhesive members 9 used for these adhesive tapes include, for example, nonwoven fabrics, woven fabrics, knitted fabrics, papers, and the like made of polyester, rayon, nylon, polypropylene, polyethylene, polyurethane, cotton, and the like. A plastic sheet or the like can be used.

The shape of the non-adhesive portion 8 is not limited to the rectangular shape as shown in FIG. 1 as in the case of the weakly-adhesive portion 4, and may be a trapezoid, a polygon, an ellipse, or other various shapes. In the case of the non-adhesive portion 8 where the adhesive layer 2 is not formed, these shapes can be formed by punching the adhesive layer 2. Further, the short side length of the non-adhesive portion 8 is the same as the short side length of the rectangular portion 5, but may be shorter.

The presence of the non-adhesive portion 8 prevents the inside of the knee joint from sticking, does not cause discomfort due to bending and stretching of the knee joint, and can significantly reduce stuffiness due to sweating. Further, since the area applied to the inside of the knee joint is the non-adhesive portion 8, it is easy to position the non-adhesive portion 8 inside the knee joint.

As described above, in the adhesive tape for fixing a knee joint according to the present invention, the region applied to the inside of the knee joint includes the non-adhesive portion 8 or the weak adhesive portion 4 to which the adhesive is partially applied, and the cut 3 Since the appropriate position and method of attachment are clarified by the application, anyone can easily perform taping. In addition, since the non-rectangular tongue-shaped portion 6 is provided at the end of the divided adhesive tape portion 7 for fixing the periphery of the patella, peeling during application is reduced, and the divided adhesive tape portion 7 is also reduced. This improves the visibility of the end portion and improves the operability during peeling. In particular, since the size of the rectangular portion 5 is in a specific range, the handleability is extremely excellent, and the knee joint is appropriately fixed.

【Example】

 Next, examples of the present invention will be shown and described more specifically, but the present invention is not limited to these, and various applications are possible without departing from the technical idea of the present invention. .

Example 1 Acrylic pressure-sensitive adhesive was dried to a thickness of 80 μm on a release liner (basis weight 64 g / m ² ) obtained by laminating polyethylene on high-quality paper and subjecting the polyethylene layer to silicone treatment. And a strong twisted cloth (basis weight: 150 g / m ² , tensile strength in the longitudinal direction: 160 N / 19 mm width) as a support on the pressure-sensitive adhesive layer, and the support, pressure-sensitive adhesive layer, release liner Was obtained.

The laminated body is subjected to a punching process, has a rectangular portion with a short side of 75 mm and a long side of 450 mm, and has a cut of 130 mm in length from the center of both short sides, and is further divided into adhesive tapes A processed product having an oval tongue extending 5 mm in length at the end of the portion was obtained. The planar shape of this is shown in FIG. The release liner of this processed product was once peeled off, and a polyester nonwoven fabric having a length of 75 mm and a width of 110 mm (basis weight 40 g / m ² , manufactured by Toray Dupont Co., Ltd., Sontara # 8010) was bonded to the central portion where no cut was provided. An adhesive tape for fixing a knee joint having a cross-sectional shape shown in FIG. 8 and a length of 75 mm and a total length of 460 mm was obtained. The release liner was split at the non-adhesive part.

(Example 2) The same as Example 1 except that the adhesive was partially applied in a strip shape at a pitch of 5 mm width and a non-application width of 10 mm width in a region applied to the inside of the knee joint. Thus, an adhesive tape for fixing a knee joint having the shape shown in FIG. 1 was obtained.

Comparative Example 1 An adhesive tape for fixing a knee joint having a length of 75 mm and a total length of 460 mm having a tongue portion was obtained in the same manner as in Example 1 except that the polyester nonwoven fabric was not bonded.

Comparative Example 2 An adhesive tape for fixing a knee joint having a length of 75 mm and a total length of 460 mm having a tongue-shaped portion was obtained in the same manner as in Example 1 except that no cut was made from the center of both short sides. .

(Comparative Example 3) The laminate obtained in Example 1 was subjected to punching to form a rectangular portion having a short side of 40 mm and a long side of 450 mm, and a length of 5 mm extending in the longitudinal direction at the end. After obtaining a processed product having an elliptical tongue-shaped part, the release liner of the processed product is once peeled off, and a polyester nonwoven fabric having a length of 40 mm and a width of 110 mm (basis weight 40 g / An adhesive tape was obtained in the same manner as in Example 1 except that m ² , Sontara # 8010 manufactured by Toray Dupont Co., Ltd. was adhered. Two of these tapes were used and both adhesive tapes were wound around the knee joint so that no gap was opened.

(Comparative Example 4) The laminate obtained in Example 1 was subjected to punching, and had a rectangular portion having a short side of 40 mm and a long side of 340 mm, and a cut having a length of 80 mm from the center of both short sides. Then, a processed product having an oval tongue extending in the longitudinal direction with a length of 5 mm was obtained at the end of the adhesive tape part which was further divided. The release liner of this processed product was once peeled off, and a polyester nonwoven fabric (40 g / m ² , basis weight 40 g / m ² , manufactured by Toray Dupont Co., Ltd., Sontara # 8010) was attached to the center of the non-adhesive portion. An adhesive tape for fixing a knee joint having a sectional shape shown in Fig. 8 and a length of 40 mm and a total length of 350 mm was obtained.

Comparative Example 5 The same procedure as in Example 1 was performed except that the laminate obtained in Example 1 was subjected to punching to obtain a processed product consisting of only a rectangular portion having a short side of 160 mm and a long side of 560 mm. Thus, an adhesive tape for fixing the knee joint was obtained. The plan shape of this is shown in FIG.

[Test for Adhering Adhesive Tape to Knee Joint] Each of the adhesive tapes obtained above was applied to the knee joint of 15 volunteers aged 30 or older, and the adherence was evaluated according to the following criteria.

(Knee Joint Pain Relieving Effect) Regarding the knee joint pain reducing effect, “the knee became much easier”, “the knee pain became slightly easier”, and “the same as when the taping was not performed” Table 1 shows the results for the corresponding number of people.

[0036]

[Table 1]

(Feeling of Wearing) The feeling of wearing was evaluated on three scales: “very comfortable”, “no problem, but a little uncomfortable”, and “very uncomfortable”. .

[0038]

[Table 2]

(Pain When Peeling Off Tape After Operation) The pain when peeling was evaluated in three stages: “can be peeled off without any problems”, “slightly painful”, and “very painful”. It is shown in Table 3.

[0040]

[Table 3]

(Operability) Regarding the operability, “Easy to attach and easy to peel off, and the end was easily recognized.” “Slightly difficult to apply but easy to peel off, and the end immediately The evaluation was made on a three-point scale: "recognizable", "easy to attach and easy to peel off, and the end could not be immediately recognized".

[0042]

[Table 4]

In Examples 1 and 2, as is clear from the above tables, better results were obtained in Comparative Example 1 to 5 in terms of pain reduction effect, wearing feeling, and operability. The second embodiment has a weak adhesive portion, and has an advantage that the manufacturing process is simplified and the production can be performed at low cost. Also, the air permeability was good and there was no feeling of discomfort, and the degree of stuffiness on the inside of the knee joint was also good. The pressure-sensitive adhesive layer was also partially coated, and did not become loose during use. On the other hand, in Example 1, the nonwoven fabric was stuck to the region applied to the inside of the knee joint, so that the wearing feeling was good. However, there was a situation in which the nonwoven fabric was somewhat stretched after prolonged wearing.

Further, with the dimensions of Comparative Example 3 or 4, a sufficient effect of reducing the knee joint was not obtained. In Comparative Example 5, the lightening effect was sufficient, but the tendency was too large as a whole, the handling was difficult, and it was difficult to find the overlapped end. On the other hand, there was also a tendency to rise from the corner of the end. In addition, in Comparative Example 1, there was pain in wearing and peeling, and in Comparative Example 2, the patellar was covered because there was no cut, and there was no pain reducing effect.

[0045]

[Effect of the invention]

 The adhesive tape for fixing the knee joint according to the present invention has a weak adhesive portion and a non-adhesive portion partially coated with an adhesive in an area applied to the inner side of the knee joint, and has a cut. The adhesive tape for use.
