Description

Technical Field

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

[0002] Medicated plasters are a common clinical treatment method, often used to treat rheumatoid arthritis or sprains and bruises. These plasters are applied thinly to the skin, allowing the medicinal ingredients to penetrate and produce anti-inflammatory, analgesic, blood-activating, meridian-clearing, and wind-dispelling effects. The medication penetrates the skin to the subcutaneous tissue at the affected area, creating a relatively high local drug concentration and thus exerting a stronger pharmacological effect.

[0003] In some existing medicated plasters, the release paper is usually very thin and adheres tightly to the plaster. When peeling off the release paper, it is difficult for users to find a suitable place to peel it off, which may cause the plaster layer and the adhesive layer to be partially stuck or damaged. At the same time, the plaster is inconvenient to cut and is not easy to apply to irregular shapes such as joints. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a medicated plaster. The design of the peel-off corners facilitates the removal of the first release paper, preventing direct contact of the medicine layer with fingers or accidental damage to the plaster while searching for the peel-off point. This also reduces uneven pulling between the release paper and the medicine layer. The easy-tear holes allow users to cut the plaster to fit irregular shapes on special areas such as joints. The breathable adhesive tape allows the plaster to adhere to the user's skin after the second release paper is peeled off, effectively preventing displacement during physical activity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plaster patch, comprising a base layer, a drug layer at the bottom end of the base layer, an anti-seepage ring at one end of the base layer corresponding to the drug layer, an adhesive layer at one end of the base layer corresponding to the anti-seepage ring, a first release paper at the end of both the adhesive layer and the drug layer away from the base layer, a tear-off corner at both ends of the first release paper, a plurality of easy-tear holes at the top end of the base layer, and breathable adhesive tape fixedly connected to the four corners of the top end of the base layer.

[0006] Furthermore, the top of the base layer has multiple vent holes.

[0007] Furthermore, a second release paper is provided at the bottom end of the breathable adhesive tape.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. The design of the peel-off corners facilitates the removal of the first release paper, preventing fingers from directly contacting the medicine layer or accidentally damaging the plaster while searching for the peel-off point. It also reduces uneven pulling between the release paper and the medicine layer. The easy-tear holes allow users to cut the plaster according to their needs, making it easy to fit irregular shapes on special areas such as joints. The breathable adhesive tape allows the plaster to be adhered to the user's skin after the second release paper is peeled off, effectively preventing the device from shifting during body movements.

[0010] 2. By setting up the anti-seepage ring, when the plaster is squeezed or the temperature changes, the medicine tends to diffuse towards the edge. The anti-seepage ring can effectively prevent the medicine from seeping out from the edge of the plaster, ensuring that the medicine is concentrated in the area where it should work.

[0015] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are 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. Example

[0017] See appendix Figure 1-3As shown, a plaster includes a base layer 1, a drug layer 3 at the bottom end of the base layer 1, an anti-seepage ring 2 at one end of the bottom end of the base layer 1 corresponding to the position of the drug layer 3, an adhesive layer 10 at one end of the bottom end of the base layer 1 corresponding to the position of the anti-seepage ring 2, a first release paper 4 at the end of both the adhesive layer 10 and the drug layer 3 away from the base layer 1, and a tear-off corner 5 at both ends of the first release paper 4, a plurality of easy-tear holes 7 at the top end of the base layer 1, and breathable adhesive tape 8 fixedly connected to the four corners of the top end of the base layer 1.

[0018] Multiple vent holes 6 are provided at the top of the base layer 1.

[0019] The bottom end of the breathable adhesive tape 8 is provided with a second release paper 9.

[0020] Working principle: With the anti-leakage ring 2, when the plaster is squeezed or the temperature changes, the medicine tends to diffuse towards the edge. The anti-leakage ring 2 can effectively prevent the medicine from seeping out from the edge of the plaster, ensuring that the medicine is concentrated in the area where it should work. With the peeling corner 5, it is easy to peel off the first release paper 4, avoiding direct contact of the medicine layer 3 with the fingers or accidental damage to the plaster when looking for the peeling position, and reducing uneven pulling between the release paper and the medicine layer 3. With the easy-tear hole 7, the user can cut the plaster according to actual needs, so as to easily fit the irregular shape of special parts such as joints. With the breathable adhesive tape 8, it can be adhered to the user's skin surface after the second release paper 9 is peeled off, which can effectively prevent the device from shifting during body activities.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
