Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and health care products technology, and in particular to an anti-sweating patch. Background Technology
[0002] Night sweats, characterized by sweating during sleep that stops upon waking, are a relatively common health issue. Prolonged night sweats not only affect sleep quality, leading to fatigue and lethargy, but may also be an external manifestation of certain underlying diseases. Currently, there are various treatments for night sweats, including medication and traditional Chinese medicine, but convenient supplementary methods are also needed in daily life to alleviate the symptoms.
[0003] Among the many methods for relieving night sweats, topical medication is a common and convenient approach. The navel, also known as the Shenque acupoint, is a traditional Chinese medicine acupoint in the body's meridian system. Traditional Chinese medicine theory believes that medication administered through the navel can reach the whole body via the flow of Qi and blood through the meridians, regulating organ function and balancing Yin and Yang. However, existing navel patches for stopping sweating have several shortcomings. Firstly, many patches are not designed to fully consider the unique concave structure of the navel, making it difficult for them to adhere tightly and preventing the medication from effectively reaching the acupoint, thus affecting the antiperspirant effect. Secondly, existing patches often lack a reasonable drug release and penetration mechanism; some patches have direct contact with the skin, easily leading to excessively high local drug concentrations and adverse reactions such as skin allergies. Patches with low drug penetration rates cannot deliver enough active ingredients to the body to exert their effects. Furthermore, most patches lack heating functions, resulting in low drug absorption and utilization. In addition, during application, the moisture in the ointment easily stains the user's clothing, adding to the washing burden.
[0004] Therefore, it is necessary to improve the existing anti-sweat patches. Utility Model Content
[0005] The purpose of this invention is to overcome the defects in the existing technology and provide an anti-sweat patch that promotes the uniform penetration of drug components into the user's navel skin, ensures drug penetration performance and absorption rate, and prevents staining of the user's clothing.
[0006] To achieve the above-mentioned technical effects, the technical solution of this utility model is: an anti-sweating patch, comprising:
[0007] The shaping piece includes a ring piece and an arch piece integrally connected to the inner side of the ring piece. The two end faces of the ring piece are an inner surface and an outer surface, respectively. The inner surface is connected to a release layer through an adhesive layer. The arch piece protrudes from the inner surface along the axial direction of the ring piece. The arch piece is densely covered with through holes. The arch piece is used to be inserted into the inside of the navel.
[0008] A slow-release isolation layer is disposed on the side of the arched piece that faces away from the external surface;
[0009] A cover is disposed on the side of the arched piece adjacent to the outer surface and surrounds the arched piece to form a storage cavity;
[0010] An antiperspirant ointment is disposed within the storage cavity.
[0011] Preferably, in order to ensure that the herbal ingredients of the antiperspirant plaster act evenly on the skin inside the navel and improve the antiperspirant effect, the side of the arched piece facing away from the external surface includes an end face and a conical face connected by a coaxial center line. The curved surface where the end face is located is spherical, and the curved surface where the conical face is located is conical.
[0012] Preferably, to avoid skin allergies, the sustained-release isolation layer is medical degreased gauze or hydrophilic nonwoven fabric.
[0013] Preferably, in order to prevent moisture from overflowing and contaminating the user's clothing during the antiperspirant process, an elastic sealing ring is also provided on the inner surface, and the sealing ring is located between the adhesive layer and the arch piece.
[0014] Preferably, in order to protect the slow-release isolation layer before use, the release layer has a cover-like structure and is enclosed by the adhesive layer and the shaping sheet to form a protective cavity, and the slow-release isolation layer is disposed in the protective cavity.
[0015] Preferably, in order to enhance drug penetration, the shaping sheet is connected to a heating element.
[0016] Preferably, in order to heat the antiperspirant, a partition is provided on the inner side of the arch to divide the storage cavity into a drug storage cavity and a heating storage cavity. The antiperspirant is filled in the drug storage cavity, and the heating element is a nano-far-infrared ceramic material filled in the heating storage cavity.
[0017] Preferably, in order to ensure the effective range of the antiperspirant, the antiperspirant covers the side of the arched sheet adjacent to the outer surface.
[0018] Preferably, in order to heat the antiperspirant, the heating element includes an electric heating patch disposed on the outer surface, the electric heating patch having a built-in heating element, the heating element being connected to a power source.
[0019] Preferably, for ease of reuse of the heating patch, the heating patch is detachably connected to the outer surface.
[0020] In summary, compared with existing technologies, this novel anti-sweating patch, when used, places the arched patch inside the user's navel, increasing the contact area between the slow-release isolation layer and the skin inside the navel. This not only prevents the antiperspirant layer from directly contacting the user's skin, making the navel difficult to clean, but also allows the medicinal components of the antiperspirant layer to pass through the pores and then through the slow-release isolation layer to contact the skin, thereby promoting the even absorption of the medicine at the navel and achieving a good anti-sweating effect.

[0031] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0032] First Embodiment
[0033] like Figures 1-3 As shown, a first embodiment of the present invention provides an anti-sweating patch, comprising:
[0034] The shaping piece 1 includes a ring piece 11 and an arch piece 12 integrally connected to the inner side of the ring piece 11. The two end faces of the ring piece 11 are an inner surface 111 and an outer surface 112, respectively. The inner surface 111 is connected to a release layer 14 through an adhesive layer 13. The arch piece 12 protrudes from the inner surface 111 along the axial direction of the ring piece 11. The arch piece 12 is densely covered with through holes 121. The arch piece 12 is used to be inserted into the inside of the navel.
[0035] The slow-release isolation layer 2 is disposed on the side of the arched piece 12 facing outwards from the external surface 112;
[0036] Cover 3 is disposed on the side of arch 12 adjacent to outer surface 112 and surrounds arch 12 to form storage cavity;
[0037] Antiperspirant ointment 4, placed inside the storage cavity.
[0038] In this embodiment of the antiperspirant patch, the shaping sheet 1 maintains its shape under pressure within a certain range. The shaping sheet 1 mainly consists of two parts: a ring sheet 11 and an arched sheet 12. The ring sheet 11 is circular, and the arched sheet 12 protrudes along the axial direction of the ring sheet 11 from the inner side. The antiperspirant ointment 4 is placed on the concave surface of the arched sheet 12 and sealed by a cover sheet 3. The main component of the antiperspirant ointment 4 is gallnut. Gallnut has the effects of astringing the lungs and reducing heat, astringing the intestines and stopping diarrhea, astringing sweat and stopping bleeding, and absorbing dampness and healing sores. In terms of antiperspirant, gallnut is often used externally. By applying gallnut to the navel (Shenque acupoint), the penetrating effect of the drug is used to achieve the effect of astringing and stopping sweating. It has a certain therapeutic effect on spontaneous sweating and night sweats. Of course, in actual use, the antiperspirant ointment 4 can also be made by adding different ingredients according to different usage needs.
[0039] When using this anti-sweat patch, tear off the release layer 14, and use the adhesive layer 13 to adhere and fix the inner surface 111 of the shaping sheet 1 ring 11 to the skin outside the user's navel. The arched sheet 12 arches towards the inside of the navel, and the arched sheet 12 makes the slow-release isolation layer 2 on its protruding surface close to the skin inside the navel. The slow-release isolation layer 2 can prevent the antiperspirant 4 from directly contacting the skin, which would cause uneven drug distribution and easily lead to local skin allergies.
[0040] It should be noted that the adhesive layer 13 in this embodiment is a medical pressure-sensitive adhesive layer. Its main production material is medical pressure-sensitive adhesive, which is usually composed of rubber-type pressure-sensitive adhesive, acrylic-type pressure-sensitive adhesive, etc. It has good adhesion and flexibility, can quickly form a good adhesion effect on the skin surface, adheres firmly, is not easy to fall off, and is also easy to remove without leaving too much adhesive residue on the skin. The low allergenicity of medical pressure-sensitive adhesive makes it suitable for most people and can reduce the risk of skin allergies. In this embodiment, both the adhesive layer 13 and the release layer 14 are arc-shaped structures, distributed in a ring array on the inner surface 111 of the ring sheet 11, and there are gaps between adjacent adhesive layers 13 and adjacent release layers 14.
[0041] Because the navel area is relatively unique, with delicate skin and a certain degree of indentation, it is prone to accumulating dirt and grime. Gallnut plasters typically have a certain degree of stickiness and oiliness. When directly applied to the navel skin, the medicinal ingredients, oils, and other excipients may seep into the crevices of the navel, making the area around the navel greasy and sticky, and potentially leaving residual drug color that is difficult to remove completely using conventional cleaning methods. Therefore, in this embodiment, the slow-release isolation layer 2 provides a certain degree of isolation and buffering, preventing the medicinal ingredients of the antiperspirant ointment 4 from directly adhering to the navel skin, thus avoiding the problem of soiling the navel and making it difficult to clean. During use, the gallnut medicinal ingredients of the antiperspirant ointment 4 are released through the through-hole 121 of the arched plate 12, then penetrate through the slow-release isolation layer 2 before contacting the skin, thereby achieving the antiperspirant effect.
[0042] Preferably, the sustained-release isolation layer 2 is medical degreased gauze or hydrophilic nonwoven fabric.
[0043] Using either of the two materials mentioned above allows the medicinal components of the antiperspirant ointment 4, whose main ingredient is gallnut, to be released slowly and continuously and penetrate into the skin, thus achieving a long-lasting effect. This avoids skin discomfort caused by direct contact with the drug and allows the medicinal components to penetrate into the navel. Furthermore, both medical degreased gauze and hydrophilic nonwoven fabric have good absorbency and breathability, enabling them to quickly absorb moisture from the ointment and form a uniform drug distribution layer. This allows the ointment to adhere more evenly to the sustained-release isolation layer 2, allowing the medicinal components to penetrate into the skin through the gaps in the gauze. Typically, the thickness of the sustained-release isolation layer 2 is between 3mm and 5mm. If the thickness is too thin, it may not be able to fully absorb the moisture and oils in the antiperspirant ointment 4, and it may be difficult to ensure the uniform distribution of the drug; if the thickness is too large, it will hinder drug penetration, prolong the time it takes for the drug to reach the skin, and thus affect the antiperspirant effect.
[0044] In addition, the sustained-release isolation layer 2 can also prevent the plaster from directly contacting the skin and the moisture after squeezing from staining clothes. By absorbing the moisture and oil in the plaster, the sustained-release isolation layer 2 reduces the possibility of the liquid in the medicine directly contacting the skin and sticking to the clothes.
[0045] A further improvement is that the raised surface of the arch piece 12 includes an end face 122 and a conical face 123 connected by a coaxial centerline. The surface where the end face 122 is located is spherical, and the surface where the conical face 123 is located is conical.
[0046] The above design utilizes the combination of the spherical end face 122 and the conical face 123 to form the convex surface of the arched piece 12, making the shape of the convex surface of the arched piece 12 closer to the shape of the skin inside the navel. This facilitates even pressure distribution on the skin inside the navel when the patch is used, allowing the medication to fully and evenly penetrate the skin at the navel, achieving a good antiperspirant effect.
[0047] A further improvement is that an elastic sealing ring 5 is also provided on the ring 11, and the sealing ring 5 is located between the adhesive layer 13 and the arch 12.
[0048] By setting a sealing ring 5, when the shaping piece 1 is fixed to the navel by the adhesive layer 13, the sealing ring 5 is sealed to the skin at the outer edge of the navel opening, preventing moisture from leaking out of the navel and contaminating the user, thus reducing the burden on the user when washing clothes. Preferably, the sealing ring 5 is a silicone rubber sealing ring, based on the fact that silicone rubber has good elasticity, high and low temperature resistance, and chemical stability. It has good breathability, allowing a certain degree of air and moisture to pass through, while being less irritating to the skin and less likely to cause allergic reactions. In addition, the surface of silicone rubber is relatively smooth, feeling comfortable when in contact with the skin.
[0049] Preferably, in this embodiment, both the cover sheet 3 and the shaping sheet 1 are transparent plastic sheets. Furthermore, the materials of the cover sheet 3 and the shaping sheet 1 are preferably polymethyl methacrylate (PMMA), which has good optical properties, high light transmittance (up to about 92%), clear and transparent appearance, good chemical stability, and generally does not cause discomfort or allergic reactions when in long-term contact with the skin. In addition, PMMA has a certain degree of hardness and strength, and can maintain its shape basically unchanged when subjected to small pressure. In this way, good contact between the sustained-release isolation layer 2 and the skin inside the navel is ensured, thereby promoting the full and uniform absorption of the drug.
[0050] Second Embodiment
[0051] like Figure 4 and Figure 5As shown, the second embodiment of the present invention provides an anti-sweating patch based on the first embodiment, the difference being that the release layer 14 has a cover-like structure and is enclosed by the adhesive layer 13 and the shaping sheet 1 to form a protective cavity, and the slow-release isolation layer 2 is disposed in the protective cavity.
[0052] In this embodiment, the adhesive layer 13 is annular, and the release layer 14 is a cover-like structure. The release layer 14 is fixedly connected to the shaping sheet 1 by the adhesive layer 13, while forming a sealed cavity to protect the sustained-release isolation layer 2. This achieves packaging isolation of the sustained-release isolation layer 2, which reduces the packaging cost of the patch. When in use, the release layer 14 only needs to be torn open so that the adhesive layer 13 on the inner patch 111 is attached to the skin on the outside of the user's navel. It can then be used for the adjunctive treatment of night sweats, making the operation convenient.
[0053] Third Embodiment
[0054] like Figure 6 As shown, the third embodiment of this utility model is an anti-sweating patch based on the second embodiment, except that the shaping sheet 1 is connected to a heating element 6.
[0055] By incorporating a heating element 6, heat can be transferred to the antiperspirant 4 during use, achieving a heating effect. This heating raises the temperature of the ointment 4, which softens the texture of the ointment, facilitating full penetration of the medication and promoting skin absorption. Furthermore, the increased temperature causes the skin's pores to dilate, promoting blood circulation and accelerating metabolism. This allows the medication to penetrate the body more easily through pores and the stratum corneum, enhancing its antiperspirant and other effects.
[0056] A further improvement is that a partition 7 is provided on the inner side of the arch plate 12 to divide the storage cavity into a drug storage cavity and a heating storage cavity. The antiperspirant ointment 4 is filled in the drug storage cavity, and the heating element 6 is a nano-far-infrared ceramic material filled in the heating storage cavity. The antiperspirant ointment 4 covers the side of the arch plate 12 adjacent to the outer surface 112.
[0057] Through the above structure, it is ensured that the antiperspirant 4 can be released through the through hole 121 through the slow-release isolation layer 2, so that the skin around the navel can fully absorb the drug ingredients of the antiperspirant 4. The septum 7 separates the antiperspirant 4 from the heating element 6, which is mainly made of nano far-infrared ceramic material. The heat generated by the heating element 6 when heated is transferred to the antiperspirant 4 through the septum 7, so that the antiperspirant 4 absorbs the heat and promotes the absorption of the drug at the navel skin.
[0058] In this embodiment, the heating element 6 is made of nano-far-infrared ceramic material. Nano-far-infrared ceramic material can efficiently absorb external energy and radiate far-infrared rays. Its nanoscale structure gives it a larger specific surface area and higher activity, enabling it to convert absorbed energy into far-infrared radiation more quickly and effectively, thereby generating heat. The spacer 7 provides a warm environment for the antiperspirant ointment 4, thereby raising the skin temperature, promoting blood circulation in clothing, and expanding pores. This also helps to promote the penetration of the gallnut drug component in the antiperspirant ointment 4 into the skin inside the navel, enhancing the antiperspirant effect. Moreover, the nano-far-infrared ceramic material has stable chemical properties and can maintain its heating performance during the storage and use of the patch. It is not easily affected by external environmental factors (such as humidity, light, etc.) and will not deteriorate or fail.
[0059] Fourth embodiment
[0060] like Figures 7-9 As shown, the fourth embodiment of this utility model is an anti-sweating patch based on the third embodiment, except that the shaping sheet 1 is connected to a heating element 6.
[0061] Specifically, the heating element 6 includes an electric heating pad 61 disposed on the outer surface 112, the electric heating pad 61 has a built-in electric heating element 62, the electric heating element 62 is used to connect to the power supply; the electric heating pad 61 is detachably connected to the outer surface 112.
[0062] Compared to the third embodiment, in this embodiment, the heating element 6 is disposed on the outer surface 112. On the one hand, this ensures sufficient space between the arched sheet 12 and the cover sheet 3 to accommodate more antiperspirant 4, thereby achieving a longer-lasting antiperspirant effect. On the other hand, in this embodiment, the heating patch 61 is detachably connected to the outer surface 112, making it convenient to remove the heating patch 61 after the antiperspirant 4 is used up and attach it to the outer surface 112 of other patches, reducing the heating cost of multiple uses. In this embodiment, the heating element 62 is connected to a connector 64 via a wire 63. The connector 64 is preferably a USB plug, and the wire 63 extends to the outside of the heating patch 61, thus facilitating power supply to the heating element 62. This allows the heating patch 61 to heat the antiperspirant 4 inside the cover sheet 3 after its temperature rises.
[0063] More specifically, a hook and loop fastener 8 is provided between the heating pad 61 and the ring plate 11. The sub-attachment 81 of the hook and loop fastener 8 is fixed to the outer surface 112, and the female attachment 82 is fixed to the heating pad 61. In this way, the heating pad 61 and the ring plate 11 are detachably connected, which facilitates the reuse of the heating pad 61.
[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
