Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, specifically to a kinesiology patch. Background Technology

[0002] When applied to the skin, kinesiology tape, under appropriate exercise, can improve blood and lymphatic circulation, relieving pain, adjusting muscle tone, and effectively stimulating the nervous system. It can alleviate or cure muscle, joint, and nervous system inflammation. The product utilizes physical therapy, is non-toxic and has no side effects, and has a good effect on strengthening the body and rehabilitation training. Its functional principle is similar to that of a human hand, continuously stretching and massaging the applied area to produce a "micro-massage" effect. Kinesiology tape has already shown good protective and rehabilitative effects on athletes in the sports field, and in the medical field, it has also shown significant advantages in the prevention and treatment of some chronic joint diseases, such as knee and lumbar joint diseases. Existing kinesiology tape products use waterproof elastic fabric as the support base and medical-grade acrylic pressure-sensitive adhesive, with the adhesive surface corrugated and not completely covering the fabric base. The thickness and breathability of kinesiology tape are similar to human skin. When no tension is applied or within the range of tension, kinesiology tape has continuous natural elasticity, providing continuous beneficial sensory input during limb movement.

[0003] Existing kinesiology patches enhance nerve sensation during use. When the ambient temperature suddenly drops, the cold sensation at the application site becomes more pronounced, causing user discomfort and affecting the product's usability in winter. Kinesiology patches with self-heating herbal ingredients cannot address the issue of significant temperature differences throughout the year, failing to resolve user comfort concerns.

[0004] Therefore, there is an urgent need to develop a kinesiology patch. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention provides a kinesiology patch that can maintain a stable temperature at the application site.

[0006] Therefore, the first aspect of this utility model provides a kinesiology patch, comprising:

[0007] Support body; one side of the support body has a groove structure;

[0009] Phase change thermal storage material dispersed in the pressure-sensitive adhesive;

[0010] An isolation layer is disposed on the side of the pressure-sensitive adhesive away from the support.

[0011] This invention integrates safe heat-storing microcapsules into a kinesiology patch. When the body heats up or the ambient temperature is high, the heat is stored in the phase change material. When the ambient temperature suddenly drops, the heat is slowly released at the phase change temperature, keeping the temperature of the patch stable. This can lower body temperature in high temperatures and maintain body temperature in low temperatures.

[0012] The implementation of this utility model is simple, and the product does not cause noticeable temperature changes, thus enhancing human comfort. It is particularly effective in the rehabilitation treatment of chronic diseases that require warmth, as it can prevent discomfort caused by poor blood circulation due to low temperatures.

[0013] In some implementations, the groove structure appears curved when viewed from above.

[0014] In some embodiments, the pressure-sensitive adhesive has a width of 40-60 mm and a height of 20-80 μm.

[0021] In some implementations, the thickness of the isolation layer is 50-200 μm.

[0022] In some implementations, the material of the insulating layer includes one or more of the following: insulating paper, polyethylene, polypropylene, and polyethylene terephthalate.

[0023] In some embodiments, the support includes one or more of cotton, rayon, and spandex elastic fabric.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. The embodiments described below are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0032] The present disclosure will be explained below with reference to embodiments. Those skilled in the art will understand that the following embodiments are for illustrative purposes only and should not be construed as limiting the scope of the disclosure. Where specific techniques or conditions are not specified in the embodiments, they are performed in accordance with the techniques or conditions described in the literature in the art or according to the product instructions. Reagents or instruments whose manufacturers are not specified are all conventional products that can be obtained commercially.

[0033] Therefore, the first aspect of this utility model provides a kinesiology patch, comprising:

[0034] Support body; one side of the support body has a groove structure;

[0035] Pressure-sensitive adhesive disposed in the groove structure;

[0036] Phase change thermal storage material dispersed in the pressure-sensitive adhesive;

[0037] An isolation layer is disposed on the side of the pressure-sensitive adhesive away from the support.

[0038] This invention integrates safe heat-storing microcapsules into a kinesiology patch. When the body heats up or the ambient temperature is high, the heat is stored in the phase change material. When the ambient temperature suddenly drops, the heat is slowly released at the phase change temperature, keeping the temperature of the patch stable. This can lower body temperature in high temperatures and maintain body temperature in low temperatures.

[0039] The implementation of this utility model is simple, and the product does not cause noticeable temperature changes, thus enhancing human comfort. It is particularly effective in the rehabilitation treatment of chronic diseases that require warmth, as it can prevent discomfort caused by poor blood circulation due to low temperatures.

[0040] In some embodiments, the groove structure is curved when viewed from above; further, the groove structure is wavy, and the pressure-sensitive adhesive disposed in the groove structure also has a wavy shape. During use, sweat produced on the human body surface can easily cause the kinesiology patch to lose its adhesiveness; the curved groove structure facilitates the drainage of sweat, thus extending the wear time of the kinesiology patch.

[0041] In some embodiments, the width of the pressure-sensitive adhesive is 40-60 mm and the height is 20-80 μm. As an example, the width of the pressure-sensitive adhesive can be 40, 45, 50, 55 or 60 mm, and the height can be 20, 30, 40, 50, 60, 70 or 80 μm.

[0042] In some embodiments, the pressure-sensitive adhesive is made of one or more of acrylic polymers, rubber polymers, polyurethane polymers, and polyester polymers; further, acrylic polymers include one or more of acrylic acid, methacrylic acid, and acrylates; and rubber polymers include one or more of natural rubber, styrene-butadiene rubber (SBR), and nitrile rubber (NBR).

[0043] In some embodiments, the enthalpy of the phase change thermal storage material is 100-400 J / g, and the phase change temperature is 20-38℃.

[0044] In some embodiments, the phase change thermal storage material has a capsule structure; the phase change thermal storage material includes a core and a wall; the core is a phase change thermal storage material, and the wall is a heat-resistant polymer;

[0045] The phase change thermal storage material includes one or more of stearic acid, lauric acid, palmitic acid, myristic acid, n-octadecane, n-nonadecane, and n-eicosane;

[0046] The heat-resistant polymer is formed by the polymerization of isocyanate and diethanolamine.

[0047] In some embodiments, the preparation method of the phase change thermal storage material includes:

[0048] Stearic acid and isocyanate are mixed to obtain an oil phase. The oil phase is then mixed with an aqueous phase containing sodium dodecyl sulfonate to obtain an oil-water emulsion. The oil-water emulsion is mixed with diethanolamine at 70°C and heated to obtain a phase change microcapsule emulsion. The emulsion is then dried to obtain a phase change thermal storage material.

[0049] In some embodiments, the particle size of the phase change thermal storage material is 0.1-150 μm; further, the average particle size of the phase change thermal storage material is 10-40 μm. As an example, the particle size of the phase change thermal storage material is 0.1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150 μm.

[0050] In some implementations, the thickness of the isolation layer is 50-200 μm. As an example, the thickness of the isolation layer can be 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, or 200 μm.

[0051] In some implementations, the support body has a length of 50-150 mm and a height of 500-600 μm. As an example, the support body can have a length of 50, 80, 100, or 150 mm and a height of 500, 510, 520, 530, 540, 550, 560, 570, 580, 590, or 600 μm.

[0052] In some implementations, the material of the insulating layer includes one or more of the following: insulating paper, polyethylene, polypropylene, and polyethylene terephthalate.

[0053] In some implementations, the isolation layer also includes silicone oil disposed on the side close to the pressure-sensitive adhesive.

[0054] In some embodiments, the support includes one or more of cotton, rayon, and spandex elastic fabric.

[0055] The phase change thermal storage capsules used in the examples and comparative examples consist of a core and a wall. The preparation method of the phase change thermal storage material is as follows: stearic acid and isocyanate are mixed at a mass ratio of 2:1 to obtain an oil phase. The oil phase is then mixed with an aqueous phase containing sodium dodecyl sulfonate at a mass ratio of 1:1 to obtain an oil-water emulsion. The oil-water emulsion is then mixed with diethanolamine at 70°C and heated to obtain a phase change microcapsule emulsion. The emulsion is then dried to obtain an ultrafine powder phase change thermal storage material with an average particle size of 10-40 μm, a phase change enthalpy of 180 J / g, and a phase change temperature of 28°C. The mass ratio of isocyanate to diethanolamine is 1:1.

[0056] Example 1

[0057] like Figure 1 As shown in the cross-sectional view, the kinesiology patch 100 of this embodiment has a heat regulation function. The kinesiology patch 100 consists of a support body 110, a pressure-sensitive adhesive 121, phase change heat storage capsules 122 dispersed in the pressure-sensitive adhesive 121, and an isolation layer 130 attached to the side of the pressure-sensitive adhesive 121 away from the support body. The support body 110 is 50 mm long and 500 μm high. One side of the support body 110 has multiple continuously distributed groove structures. The groove structures are used to embed the pressure-sensitive adhesive 121, so that the phase change heat storage capsules 122 in the pressure-sensitive adhesive 121 can diffuse heat in the groove structures. The pressure-sensitive adhesive 121 has a height of 60 μm and a width of 40-60 mm. The main component of the pressure-sensitive adhesive 121 is acrylic pressure-sensitive adhesive. The isolation layer 130 is made of release paper and silicone oil on the surface of the release paper. The silicone oil is disposed on the side close to the pressure-sensitive adhesive. The thickness of the release paper is 120 μm. A top view of the kinesiology patch with part of the isolation layer removed is shown below. Figure 2 As shown, the pressure-sensitive adhesive is distributed in a water ripple pattern.

[0058] The preparation method of Kinesiology Patch 100 includes the following steps:

[0059] Take a phase change thermal storage material with an average particle size of 10 μm (phase change enthalpy of 180 J / g, phase change temperature of 28℃) and add it to an acrylic pressure-sensitive adhesive solution (mass ratio of 1:1). Stir at high speed for 30 min, add isocyanate, and stir for another 30 min. Sample preparation was performed using a comma coating method. A medical pressure-sensitive adhesive coating liquid containing phase-change heat storage microcapsules was uniformly coated onto the side of the release liner coated with silicone oil. As the release liner with the adhesive coating moved forward, a crankshaft or eccentric wheel was horizontally mounted on the adhesive surface, causing a comb-shaped metal sheet to move laterally across the adhesive surface, creating wavy stripes on the adhesive surface to form empty adhesive positions. The release liner with the textured pressure-sensitive adhesive layer was then fed into an oven and dried at 150°C to evaporate the solvent and remove the pressure-sensitive adhesive, resulting in a dry coating thickness of 60 μm. A spandex elastic fabric support was then bonded to the adhesive side of the release liner to form the main shaft of the kinesiology patch. The patch was then slit to a width of 50 mm to obtain kinesiology patch 1 with heat regulation function.

[0060] Example 2

[0061] The kinesiology patch with heat regulation function in this embodiment is prepared by the following method:

[0062] Phase change thermal storage material with an average particle size of 20 μm (phase change enthalpy of 180 J / g, phase change temperature of 28 °C) was added to an acrylic pressure-sensitive adhesive solution (mass ratio of 1:1), and stirred at high speed for 30 min. Isocyanate was then added, and the mixture was stirred for another 30 min. The preparation method was the same as in Example 1, resulting in kinesiology patch 2.

[0063] Comparative Example 1

[0064] The difference between this comparative example of kinesiology tape and Example 1 is that this comparative example omits the phase change heat storage material and directly mixes the pressure-sensitive adhesive with the curing agent to prepare a conventional kinesiology tape 3.

[0065] Test case

[0066] Three types of kinesiology patches were placed in a 36℃ oven for 2 hours. After being removed, they were pasted onto a thermometer, covered with a cotton cloth, and the temperature changes were tested. The results showed that the rates of temperature drop were as follows: kinesiology patch 3, kinesiology patch 1, and kinesiology patch 2.
