When in use, the black plaster is applied to the area of discomfort for the patient, allowing the plaster to penetrate the skin and produce anti-inflammatory, analgesic, and blood-activating effects.
[0003] According to application number CN202323337288.5, a medicated plaster is characterized by comprising: a protective sleeve and a plaster layer; the protective sleeve covers both sides of the plaster layer; the plaster layer comprises: a base layer, a first adhesive layer, an anti-seepage ring, and a dustproof layer; the base layer, the first adhesive layer, and the dustproof layer are arranged in sequence; the anti-seepage ring penetrates the dustproof layer and is fixedly disposed on one side of the first adhesive layer; the interior of the anti-seepage ring is suitable for placing medicine; the anti-seepage ring has a first sealing part, which covers the anti-seepage ring, and the first sealing part and the first adhesive layer are respectively located on opposite sides of the anti-seepage ring; the base layer has two or more folded holes, which are arranged around the annular structure of the anti-seepage ring. This application has a simple overall structure, is convenient to use, and has high sealing performance. Under the constraint of the anti-seepage ring and the first sealing part, the medicine is firmly fixed and its fluidity is reduced.
[0004] Based on the above, when using existing black plaster patches, sweating at the site where the plaster is applied can easily affect the adhesion of the plaster. Furthermore, when applying the plaster to certain areas such as the wrist, the varying thickness of the wrist makes it inconvenient to apply the plaster, thus affecting its usability. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a black medicated plaster with sweat-absorbing function. This solves the problems that, during the use of existing black medicated plasters, sweating at the site where the plaster is applied can easily affect its adhesion. Furthermore, when applying the plaster to certain areas such as the wrist, the varying thickness of the wrist makes it inconvenient to apply the plaster, thus affecting its usability.
[0006] The purpose and efficacy of this utility model's black medicated plaster patch with sweat-absorbing function are achieved by the following specific technical means:
[0007] A black medicated plaster with sweat-absorbing function includes an insulating layer, breathable holes, a dust-free paper layer, an adhesive layer, a medicated plaster layer, a sweat-absorbing mechanism, a positioning mechanism, and an adhesive removal mechanism. Multiple breathable holes are provided, located on the inner side of the insulating layer. The dust-free paper layer is adhered to the upper surface of the insulating layer. The adhesive layer is adhered to the upper surface of the dust-free paper layer. The medicated plaster layer is adhered to the upper surface of the adhesive layer. The sweat-absorbing mechanism is located at the lower end of the adhesive layer. The positioning mechanism is located at the upper end of the adhesive layer. The adhesive removal mechanism is located on the outer side of the insulating layer.
[0008] Furthermore, the sweat-absorbing mechanism includes: sweat-absorbing holes; multiple sweat-absorbing holes are provided, and all multiple sweat-absorbing holes are opened on the inner side of the adhesive layer.
[0009] Furthermore, the positioning mechanism includes: a release paper cover, a release paper strip, and an easy-tear strip; the release paper cover is pasted on the upper surface of the adhesive layer; the release paper strip is pasted on the upper surface of the adhesive layer; and the easy-tear strip is fixedly connected to the outside of the release paper strip.
[0010] Furthermore, the adhesive removal mechanism includes: folding grooves; multiple folding grooves are provided, and the multiple folding grooves are respectively opened on the inner side of the isolation layer, the dust-free paper layer and the adhesive layer.
[0011] Furthermore, the adhesive removal mechanism also includes an easy-remove piece; the easy-remove piece is attached to the corner of the adhesive layer.
[0012] Furthermore, the adhesive removal mechanism also includes: a plastic sheet, a storage strip, and a fixing piece; the plastic sheet is attached to the lower end face of the isolation layer; the rear end of the storage strip is attached to the lower end face of the isolation layer, and the front end face of the storage strip is attached to the lower end face of the plastic sheet; the fixing piece is fixedly connected to the front end of the storage strip.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention utilizes a sweat-absorbing mechanism to absorb sweat from the area where the black plaster is applied. When the plaster is attached to the patient's body, sweat at the application site comes into contact with the dust-free paper layer through the sweat-absorbing pores. The dust-free paper layer absorbs the sweat, preventing it from affecting the adhesion of the plaster layer and improving comfort. A positioning mechanism ensures the alignment of the black plaster. When applying the plaster, the release strip can be peeled off first, and the exposed part of the adhesive layer can be applied to the appropriate position on the patient's body. The coverage area of the plaster layer can then be compared. If there is a deviation, the adhesive layer can be peeled off and readjusted before reapplication. Since only a small portion of the adhesive layer is in contact with the patient's skin, adjustments are easier, making the operation convenient and improving accuracy. Finally, a plaster removal mechanism allows for the application and removal of the black plaster, enabling easy folding and storage. The groove design allows for bending and pasting of the black plaster when applied to joints such as the wrist, resulting in a better fit to the skin and improved adaptability. The plastic sheet makes removal easier and more efficient. After removal, the plaster can be rolled up and then wrapped with the storage strip for convenient storage. The design incorporates several features to prevent the black plaster from sticking to other items when discarded. These features include: absorption of sweat at the plaster application site to prevent sweat from affecting the adhesive layer and improving comfort; alignment of the plaster for improved application accuracy; and the ability to apply and remove the plaster to different surfaces, enhancing adaptability and efficiency.
