Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine plaster technology, and in particular to a leak-proof, visible joint and acupoint traditional Chinese medicine plaster. Background Technology

[0002] Traditional Chinese medicine plasters are topical preparations that apply Chinese herbal ingredients directly to the skin surface, achieving therapeutic effects through penetration and absorption. They are commonly used to relieve pain, reduce inflammation, or treat some skin diseases, and are convenient and non-invasive.

[0003] Traditional Chinese medicine plasters typically consist of medicinal ingredients, a plaster base, and an adhesive layer. The medicinal ingredients are finely processed to act directly on the skin, the base provides support and stability, and the adhesive layer ensures the plaster adheres firmly to the skin, allowing the medicine to be released effectively.

[0004] Traditional Chinese medicine plasters are prone to leakage, mainly due to insufficient sealing and adhesion of the plaster, leading to the loss or uneven distribution of medicinal ingredients during use, thus affecting efficacy. Furthermore, because the plasters adhere tightly, changes on the skin cannot be directly observed. If allergic reactions or discomfort occur, users often cannot detect them in time and take appropriate measures. These problems not only affect treatment effectiveness but also have adverse effects on skin health. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 One embodiment of this utility model is a leak-proof, visible herbal patch for joint acupoints, comprising:

[0035] Skin-friendly layer 1 is a circular medical-grade transparent silicone film with a diameter of 40mm and a thickness of 0.1mm. It has a light transmittance of 90% and is used to directly contact the skin and carry traditional Chinese medicine ointments / liquids.

[0036] Leak-proof layer 2 is a TPU waterproof and breathable membrane covering the back of skin-friendly layer 1, with a thickness of 0.05mm and a water vapor permeability of 5000g / m². 2 / 24h, the edge extends to the inner edge of the elastic fixed wing 3;

[0037] Elastic fixing wings 3, surrounding the skin-friendly layer 1 with four petal-shaped elastic non-woven fabric, each petal is 30mm long and 15mm wide, with a breaking elongation of 200%, and the inner surface is coated with medical pressure-sensitive adhesive with an initial tack of 1.8N / cm and a holding power of more than 24h.

[0038] Release layer 4 is a silicone paper protective layer covering the outer surface of the elastic fixing wing 3. The edge of the leak-proof layer 2 extends 5mm beyond the edge of the skin-friendly layer 1 and is seamlessly bonded to the inner edge of the elastic fixing wing 3 by hot pressing. The surface of the skin-friendly layer 1 has an annular groove for holding the traditional Chinese medicine ointment / liquid, with a groove depth of 0.2mm. The medical pressure-sensitive adhesive of the elastic fixing wing 3 uses an acrylic adhesive with a coating amount of 80g / m². 2 The skin-friendly layer 1 has micropores with a diameter of 5μm evenly distributed for the release of active ingredients of the drug. The surface of the patch is printed with a knee joint acupoint positioning mark, and the distance between the mark and the center of the skin-friendly layer 1 is 10mm. The adhesion strength between the anti-leakage layer 2 and the skin-friendly layer 1 is 1.2N / cm. The thickness of the release layer 4 is 0.03mm, and the peel force is 5g / 25mm.

[0039] Working principle: First, the medical-grade transparent silicone membrane of the skin-friendly layer 1 directly contacts the skin. Its surface has annular grooves that hold the herbal ointment / liquid. The ointment / liquid is continuously released into the skin through the 5μm diameter micropores on the skin-friendly layer 1. The leak-proof layer 2, a TPU waterproof and breathable membrane, covers the back of the skin-friendly layer 1, blocking the outward penetration of the liquid while allowing moisture to escape. The four-petal flower-shaped elastic non-woven fabric of the elastic fixing wings 3 surrounds the skin-friendly layer 1. The medical pressure-sensitive adhesive on its inner surface adheres to the skin after the release layer 4 is removed. When the joint flexes and extends, the elastic non-woven fabric stretches synchronously with the skin's 40% elasticity. The petal-shaped design disperses stress to the four wings to prevent the edges from lifting. The transparency of the skin-friendly layer 1 allows medical staff to directly observe the skin condition. The knee joint acupoint positioning marks on the surface of the patch assist in precise alignment with the acupoints. The edge of the leak-proof layer 2 extends 5mm beyond the edge of the skin-friendly layer 1 and is heat-pressed together with the elastic fixing wing 3 to form a fully bonded leak-proof structure, ensuring that the Chinese medicine ointment / liquid does not leak out and continues to act on the acupoints.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
