AI Technical Summary
Existing external plaster patches are prone to fall off during use, which has poor breathability, hinders drug penetration, affects therapeutic efficacy, and increases thickness to limit joint or muscle movement.
A plaster patch including a wavy muscle patch, a drug layer, a tape layer and a release paper were designed. The wavy muscle patch increases the contact area with the skin, the drug layer is arranged in a dot matrix to improve drug penetration, the tape layer provides fixing force, and the release paper protects the tape layer.
It improves the adhesion of the plaster patch, enhances the efficacy of the drug, improves the comfort of use, and avoids the problem of shedding, ensuring that the drug directly acts on the affected area.

Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an external plaster patch. Background Art
[0002] External plasters come in various forms, and the common ones are as follows: Traditional plasters: 1. Black plasters: Made with vegetable oil and lead oxide as the matrix and added with traditional Chinese medicines, they need to be softened by heating before use; 2. White plasters: Made with vegetable oil and official powder as the matrix and also need to be softened by heating; Modern plasters: 1. Rubber plasters: With rubber as the main matrix, they can be directly applied at room temperature and are convenient to use; 2. Cataplasms: With water-soluble polymer materials as the matrix, they have a large drug loading capacity, good air permeability, and little skin irritation; 3. Transdermal patches: Using high-tech controlled release technology, the drugs are slowly released and have a long-lasting effect; Other forms: 2. Gel plasters: With gel as the matrix, they are cool and comfortable, suitable for joint pain and muscle soreness; 3. Traditional Chinese medicine application agents: Mixing traditional Chinese medicine powders or extracts with excipients and directly applying them to the affected area. The characteristic is that the drugs cover the patch, often resulting in poor adhesion and easy detachment.
[0003] Muscle tapes have good extensibility. Disadvantages of combining muscle tapes with drugs: 1. Poor air permeability: The superposition of muscle tapes and plasters may affect skin ventilation. Prolonged use is likely to cause stuffiness, sweat accumulation, and even skin inflammation; 2. Affected drug absorption: Muscle tapes may hinder the drug penetration of plasters and affect the curative effect; 3. Limited movement: The superposition of the two may increase the thickness and limit the movement of joints or muscles. Summary of the Invention
[0004] The plaster patch described in the present invention includes: a wavy muscle tape layer, a drug layer, an adhesive layer, and a release paper; the wavy muscle tape layer is distributed from the outside to the inside on the adhesive layer and has an increased density in the middle area, so it is suitable for large-sized plasters. The wavy muscle tape layer and the drug layer are distributed at intervals, and the distribution area of the drug layer is larger than the area of the wavy muscle tape layer, which is more conducive to the exertion of the drug curative effect.
[0005] Wavy muscle tape layer: Made of wavy muscle tape materials with elasticity and air permeability, such as pure cotton stretch fabric, spandex, etc. The wavy design can increase the contact area with the skin, improve the fitting degree and comfort, and is also conducive to the volatilization of sweat.
[0006] Drug layer: Arranged in a dot matrix pattern and coated on the inner side of the wavy muscle tape layer, containing traditional Chinese medicine or western medicine ingredients required for treatment, such as anti-inflammatory and pain-relieving, promoting blood circulation to remove blood stasis and other drugs.
[0007] Adhesive layer: Made of low-allergenic medical glue and coated on the outside of the wavy muscle tape layer, used to fix the plaster patch on the skin surface.
[0008] Release paper: Covered on the outside of the adhesive layer, used to protect the adhesive layer and torn off before use.
[0009] Furthermore, the wave height of the wavy myopatch layer is 0.5 - 2 mm, which can be adjusted according to different parts and requirements.
[0010] Furthermore, the drug layer can adopt various dosage forms, such as ointments, gels, patches, etc., and can be selected according to the drug properties and efficacy requirements.
[0011] Furthermore, the adhesive tape layer can adopt medical adhesive tapes with good air permeability, such as non-woven fabric adhesive tapes, PU film adhesive tapes, etc., to improve comfort.
[0012] Furthermore, the plaster patch can be designed into different shapes and sizes, such as square, round, rectangular, etc., to adapt to different parts and requirements.
[0013] Advantages of the present invention: 1. Improve adhesion: Overcome the problem that the patch itself is prone to falling off. The wavy myopatch layer increases the contact area with the skin, improves the fitting degree, and the adhesive tape layer provides additional fixing force, effectively preventing the plaster patch from falling off; 2. Enhance drug efficacy: The dot matrix arrangement can ensure ductility. The drug layer acts directly on the affected area, and the wavy myopatch layer promotes drug penetration, improving drug efficacy; 3. Improve comfort: The wavy myopatch layer has good elasticity and air permeability, reducing skin stuffiness and discomfort; 4. The present invention has both physical therapy effects and can have anti-inflammatory and analgesic effects, avoiding the problem of easy falling off. Brief Description of the Drawings
