Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a novel patch. Background Technology

[0002] Traditional Chinese medicine patches are preparations in which medicinal ingredients are mixed with a base and applied to the skin. They can be absorbed through the skin to exert local or systemic therapeutic effects. The medicinal ingredients are diverse; for example, frankincense and myrrh can promote blood circulation and remove blood stasis, while coptis and phellodendron can clear heat and detoxify. The base includes rubber, rosin, etc. Rubber provides good adhesion and elasticity, rosin increases adhesion and prevents drug volatilization, and there are also hydrophilic bases such as sodium carboxymethyl cellulose. During preparation, the effective components of the medicine are first extracted: water-soluble components are extracted with water, such as astragalus polysaccharides; fat-soluble components are extracted with organic solvents, such as peppermint oil. Then, the medicine is mixed with the base. It utilizes the principle of skin penetration to allow the medicine to act continuously.

[0003] Chinese Patent No. CN202526619U discloses a patch. The patch is quadrilateral in shape and comprises, from top to bottom, a protective layer, a medicated layer, and a backing layer. At least one of the four corners of the medicated layer is chamfered, preferably all four corners are chamfered, and the chamfers are either right angles or rounded corners. Its advantages are: the protective layer of the patch is easy to peel off and avoids contact with the medicated layer, thus preventing it from affecting the adhesion of the medicated layer and ensuring the affinity between the medicated layer and the skin; even if the base of the patch has strong adhesiveness, it is easy to peel off from the skin.

[0004] In the medical and healthcare fields, patches are widely used as a common method of drug delivery or care. However, these devices, or similar patches, suffer from a serious problem of insufficient breathability. Structurally, most patches use highly sealing materials as the matrix or backing to ensure stable drug adhesion, which, while preventing easy drug loss, neglects the skin's need for respiration. Skin needs to exchange gases with the outside environment. When patches are tightly adhered for extended periods with poor breathability, sweat on the skin surface cannot evaporate effectively, creating a moist environment between the patch and the skin. This environment easily breeds bacteria and fungi, leading to skin infections such as folliculitis and tinea. Furthermore, prolonged lack of breathability causes the skin to feel stuffy and hot, resulting in excessive hydration of the stratum corneum, weakening the skin barrier function, and causing discomfort such as skin allergies, itching, and redness. This seriously affects the user experience and health, reducing the safety and comfort of patch use. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-3 As shown, a novel patch includes an elastic cloth 1, a medicated cotton core 2 fixedly connected to the middle of the top of the elastic cloth 1, a through hole 6 through the axis of the top of the elastic cloth 1, a cleaning layer 3 provided in the middle of the bottom of the elastic cloth 1, and a removable film 4 and a removable film 2 5 respectively provided at the top and bottom of the elastic cloth 1.

[0020] In practical use, this solution treats wounds by setting the medicated cotton core 2 on the elastic fabric 1, and cleans the wound by setting the cleaning layer 3, which enhances the antibacterial ability of the patch, reduces the risk of infection, and helps the wound heal faster.

[0021] Specifically, the cleaning layer 3 includes an elastic cloth 2 31, which is placed at the bottom center of the elastic cloth 1, and an oxygen cotton pad 32 is fixedly connected to the axis of the elastic cloth 2 31 at the end away from the elastic cloth 1.

[0022] Elastic fabric 2 31 has an adhesive layer 33 bonded to the four sides of the end away from elastic fabric 1 1;

[0023] After the medicated cotton 2 on the elastic fabric 1 is attached to the wound, the oxygen cotton pad 32 on the elastic fabric 2 31 is aligned with the through hole 6 on the elastic fabric 1. Then, the elastic fabric 2 31 is attached to the bottom of the elastic fabric 1 through the adhesive layer 3 33, so that the oxygen cotton pad 32 is attached to the affected area through the through hole 6.

[0024] The active oxygen cotton pad 32 in this solution is existing technology. It is composed of medical cotton pads and active oxygen oil. The main component of active oxygen oil is ozone. In terms of sterilization and disinfection, it utilizes the strong oxidizing properties of ozone to destroy the structure of bacteria, viruses, and fungi, inhibiting and killing common pathogens. It can be used for wound and skin disinfection. In terms of anti-inflammation, it can regulate the release of inflammatory cytokines, reduce inflammatory responses, relieve skin redness and itching, and improve local blood circulation to reduce inflammation.

[0025] The release film 1 (4) and release film 2 (5) used in this solution are both existing technologies. Release film 1 (4) and release film 2 (5) are papers used to prevent the patch from sticking when not in use. They are usually made by applying a special coating to materials such as paper or plastic film, for example, coating glassine paper with a silicone release agent. Their low surface tension makes it difficult for the adhesive part of the patch to stick. Their function is based on low surface energy characteristics. The adhesive in the patch has high surface energy. According to the principles of like dissolves like and surface energy matching, the adhesive easily sticks to high surface energy objects such as skin, while the release paper does not easily form an adhesive force. When in use, peeling off the release paper allows the patch to be easily removed and applied to the skin.

[0026] The elastic fabric 1 and elastic fabric 2 31 used in this solution are existing technologies. They are made of spandex fiber and other fibers. Spandex fiber is highly elastic and does not shrink easily. Combined with cotton fiber and polyester fiber, cotton fiber provides moisture absorption for skin comfort, while polyester fiber enhances strength and abrasion resistance. Its elasticity comes from the stretchable soft segments and fixed support of the hard segments of the spandex molecular chain. After the external force is removed, the soft segments recover under the action of the hard segments, allowing the elastic fabric to quickly recover. It has obvious advantages in the application of medicated patches. It has excellent fit. When used on joints such as knees and elbows, because these areas are frequently used, ordinary medicated patches cannot deform with the bending of the joint and are prone to falling off or not covering the skin well. The elasticity of the elastic fabric allows the medicated patch to stretch and contract with the joint movement, ensuring that the medicated patch fits the skin tightly and the drug continues to exert its effect. It is highly comfortable, the soft texture reduces skin friction and lowers the risk of allergies and damage. Good breathability allows the skin to breathe normally and avoids discomfort such as stuffiness and itching caused by prolonged medicated patch coverage.

[0027] The adhesive layers 11, 12, and 33 used in this solution are all medical pressure-sensitive adhesives in existing technology. They are pressure-sensitive, easy to use, and can be applied with a single press. They have strong adhesion, can firmly adhere to the skin, and have the advantages of low allergenicity and good breathability. Their components include rubber, polyisobutylene, polyurethane, etc., which can improve adhesion and durability, and ensure comfort and breathability. Hot melt adhesive is solid at room temperature and becomes liquid when heated. It has strong adhesion, good water resistance, and is suitable for various backing materials. Common components include rubber. Natural rubber is extracted from rubber trees and has good elasticity, adhesion, and breathability. It is a traditional material that can fix and protect the ointment, allowing the ointment to adhere closely to the skin and promote drug absorption. The adhesive in medical plaster is composed of rubber, tackifiers, softeners, fillers, etc., and has good adhesion and elasticity, which can prevent the plaster from falling off.

[0028] Furthermore, an adhesive layer 2 12 is glued to the four sides of the bottom end of the elastic fabric 1. The removable film 2 5 is glued to the bottom end of the elastic fabric 1 through the adhesive layer 2 12, and the removable film 2 5 covers the back end of the elastic fabric 2 31.

[0029] When using the cleaning layer 3, first peel off the second peel-off film 5 from the back of the elastic cloth 1. The second peel-off film 5 is mainly used to protect the cleaning layer 3 from external contamination. At the same time, the second peel-off film 5 is set to protect the cleaning layer 3 from being lost or falling off.

[0030] Furthermore, the circumferential dimension of the elastic fabric 31 is larger than that of the through hole 6, and the circumferential dimension of the oxygen cotton sheet 32 ​​is adapted to the circumferential dimension of the through hole 6.

[0031] The circumference of the elastic cloth 31 is larger than that of the through hole 6, so that even when the cleaning layer 3 is not used, the elastic cloth 31 can block the through hole 6, preventing external contamination from entering the affected area through the through hole 6.

[0032] Furthermore, an adhesive layer 11 is glued to the four sides of the top of the elastic fabric 1, and the film 4 is glued to the top of the elastic fabric 1 through the adhesive layer 11, so that the film 4 can cover the top of the elastic fabric 1 with the cotton core 2.

[0033] By setting up a removable film 4, the cotton core 2 on the elastic fabric 1 is protected from external contamination.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
