Description

Technical Field

[0001] This utility model relates to the field of plaster technology, specifically a self-adhesive breathable plaster. Background Technology

[0002] Medicated plasters are mainly used to treat boils, carbuncles, and reduce swelling and pain. Because medicated plasters are applied thinly to the skin, they contain potent medicinal ingredients with strong aromas and flavors, along with guiding herbs to direct the flow of qi and blood directly to the affected area. Therefore, they can penetrate the skin to produce anti-inflammatory, analgesic, blood-activating, qi-nourishing, blood-tonifying, meridian-clearing, muscle-strengthening, bone-strengthening, orifice-opening, bone-penetrating, wind-dispelling, and cold-dispersing effects. When applied to the skin, the plaster stimulates nerve endings, causing a reflex that dilates blood vessels, promotes local blood circulation, improves the nutrition of surrounding tissues, and achieves the purpose of reducing swelling, inflammation, and pain.

[0003] Although medicated plasters can be adhered to a patient's skin through an adhesive layer, the contact between the adhesive layer and the medicated area of ​​the plaster causes interference between the medicated and non-medicated areas. For example, sweat and other substances from the outside of the plaster can diffuse into the medicated area, causing contamination and bacterial growth. Also, the medication in the medicated area can easily spill into the non-medicated area, resulting in a rapid decrease in the effectiveness of the medicated plaster and poor usability.

[0019] 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.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 3 As shown, this embodiment of the self-adhesive breathable plaster includes a plaster base layer 1. A plaster groove is provided on one side of the plaster base layer 1. A plaster core layer 2 is provided within the plaster groove of the plaster base layer 1. An isolation layer 4 is provided on the side of the plaster core layer 2 closest to the plaster base layer 1. The isolation layer 4 is an impermeable layer. A transition layer 5 is provided on the inner side of the isolation layer 4 closest to the plaster core layer 2. An absorbent layer 6 is provided between the transition layer 5 and the isolation layer 4. The plaster base layer is located on the side of the isolation layer 4 furthest from the absorbent layer 6. The surface of the plaster has a barrier layer 8. On the side of the barrier layer 8 away from the isolation layer 4, the surface of the plaster base layer 1 has an adhesive layer 9. The plaster base layer 1 has ventilation holes 11. A protective layer 10 is provided on one side of the plaster base layer 1. This increases the barrier and transition absorption protection on the outside of the plaster core layer 2 of the plaster, reduces the mutual interference between the plaster area and the non-plaster area of ​​the plaster, reduces the overflow of the plaster medicine, increases the durability of the plaster's efficacy, improves the antibacterial properties of the plaster, and makes the self-adhesive breathable plaster easy to peel off.

[0022] Specifically, an antibacterial layer 7 is provided between the isolation layer 4 and the base layer 1 of the plaster. The antibacterial layer 7 is made of nano-silver antibacterial layer. Nano-silver antibacterial can reduce inflammatory response and reduce the degree of inflammation by reducing the release of inflammatory mediators.

[0023] Furthermore, the interior of the absorbent layer 6 is filled with superabsorbent polymer beads, which can quickly absorb and solidify moisture. The surface of the absorbent layer 6 is made of nano-silver nonwoven fabric, which has antibacterial properties.

[0024] Furthermore, the barrier layer 8 is made of bamboo charcoal fiber cotton, which has the advantages of moisture absorption and breathability, antibacterial and bacteriostatic properties, warmth in winter and coolness in summer, and environmental friendliness. The protective layer 10 is made of release paper, which covers the surface of the plaster and is easy to peel off from the plaster.

[0025] Furthermore, a first connecting layer 3 is provided between the plaster core layer 2 and the isolation layer 4, and a second connecting layer 61 is provided between the absorbent layer 6 and the isolation layer 4. The first connecting layer 3 and the second connecting layer 61 are made of medical adhesive, which makes the connection convenient.

[0026] Furthermore, the transition interlayer 5 is made of antibacterial silicone, which has a certain degree of skin-friendly adhesion. The antibacterial silicone containing silver ions can prevent bacteria by releasing silver ions. The plaster base layer 1 is made of high-density non-woven fabric, which is lightweight, high-strength, soft and breathable.

[0027] Furthermore, the plaster base layer 1 has tear strips 12 on both sides opposite to each other, and the adhesive layer 9 has a side strip reserved on the plaster base layer 1 on the side away from the barrier layer 8, making the self-adhesive breathable plaster easy to peel off.

[0028] The method of use in this embodiment is as follows: Peel off the release paper from the protective layer 10 of the plaster. The adhesive layer 9 of the plaster adheres the plaster to the skin. Because a barrier layer 8, an isolation layer 4, an absorbent layer 6, and a transition layer 5 are provided between the adhesive layer 9 and the plaster core layer 2, and the absorbent layer 6 is filled with superabsorbent polymer beads, the barrier layer 8 is made of bamboo charcoal fiber cotton, and the transition layer 5 is made of antibacterial silicone, the barrier, transition, and absorption protection on the outside of the plaster core layer 2 is increased. This reduces the mutual interference between the plaster area and the non-plaster area of ​​the plaster, minimizes the leakage of the plaster medication, and increases the duration of the plaster's efficacy. The plaster is made by setting a plaster core layer 2 and an adhesive layer 9 on the base layer 1 of the plaster. The base layer 1 of the plaster has ventilation holes 11, and a self-adhesive breathable plaster is produced. The plaster has a nano-silver antibacterial layer 7 and a nano-silver non-woven fabric layer on the surface of the absorbent layer 6, as well as a barrier layer 8 made of bamboo charcoal fiber cotton. Multiple antibacterial materials are set between the plaster area and the non-plaster area of ​​the plaster to improve the antibacterial performance of the plaster. The plaster base layer 1 has tear strips 12 on opposite sides, and an edge strip is reserved on the plaster base layer 1 on the side of the adhesive layer 9 away from the barrier layer 8 to make the self-adhesive breathable plaster easy to tear off.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
