Description

Technical Field

[0001] This invention relates to the field of external application of traditional Chinese medicine patches, and in particular to a black plaster magnetic therapy patch of traditional Chinese medicine and its application. Background Technology

[0002] Black plaster, as a traditional Chinese medicine external preparation, has long been used for joint pain, muscle strain, wind-cold-dampness syndrome, and soft tissue discomfort due to its convenient use, clear target area, and continuous application. Existing black plasters typically incorporate Chinese herbal ingredients into the plaster formula, utilizing local application to promote blood circulation, dispel wind and cold, relax muscles and tendons, reduce swelling and relieve pain, thus possessing certain external therapeutic effects.

[0003] Meanwhile, magnetic therapy patches, as a common external physiotherapy product, typically use magnetic elements within the patch to create a magnetic field at the application site, thus meeting the needs for local physiotherapy and relieving discomfort. Existing technologies also include product designs that combine traditional Chinese medicine patches with magnetic therapy structures, aiming to achieve a synergistic effect of multiple external treatments.

[0004] However, existing products still have some shortcomings. First, some existing black plaster products have a relatively simple structure, usually focusing only on the medicinal layer itself and lacking a layered design adapted to the magnetic therapy structure, resulting in insufficient synergy between the external application of traditional Chinese medicine and the magnetic therapy effect. Second, some existing magnetic therapy patches, when combined with the plaster medicinal layer, are prone to problems such as unstable interlayer bonding, insufficient application comfort, and easy lifting of the edges, affecting the use effect and user experience. Third, some existing patch products do not adequately consider breathability, anti-adhesion, and overall stability, which can easily cause a stuffy feeling when applied for a long time, and are not convenient to store and use. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a traditional Chinese medicine black plaster magnetic therapy patch and its application.
