Description

Technical Field

[0001] The utility model relates to the technical field of acne patches, in particular to a hydrocolloid acne patch with a marking signal of a medicine coating area. Background Art

[0002] Acne, or blackheads, is a common skin disease that affects a large number of teenagers and adults around the world. The appearance of acne is often related to multiple factors such as excessive secretion of sebum, abnormal metabolism of hair follicle keratin, and bacterial infection. There are many ways to treat acne, from daily skin cleansing care to professional medical intervention.

[0003] In the market, acne patches are popular as a convenient local treatment product. They can cover acne locally, create a moist treatment environment, and directly act on the problem area through drug ingredients. However, acne patches in the prior art still have some shortcomings:

[0004] Non-localized drug release: Although existing acne patches can provide drugs, the drugs are usually distributed over the entire area of ​​the patch. This means that the drugs may not be concentrated on the acne areas that need treatment the most, reducing the efficacy.

[0005] Insufficient user feedback: Users are usually unable to determine whether the drug has been fully released, and it is difficult for them to understand the working status of the acne patch, which affects their confidence in the product and their compliance with treatment.

[0006] Single function: Most acne patches only provide simple coverage or basic drug sustained release, lacking innovative multifunctional designs, such as functional indications that change according to treatment progress. In view of this, we propose a hydrocolloid acne patch with a drug coating area marking signal. Utility Model Content

[0007] The purpose of the utility model is to provide a hydrocolloid acne patch with a marking signal of a drug coating area to solve the problems raised in the above-mentioned background technology.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A hydrocolloid acne patch with a drug coating area marking signal includes a hydrocolloid base layer. The hydrocolloid base layer has good air permeability and hygroscopicity, can effectively absorb wound secretions, reduce the possibility of microbial growth, and promote wound healing. The hydrocolloid base layer is provided with a plurality of micropores, and the micropores are filled with marking signal substances. The marking signal substances can contact with wound secretions and produce color changes, thereby providing users with an intuitive indication of the degree of acne inflammation. A drug layer is provided in the middle of the bottom of the hydrocolloid base layer, and the drug layer is used to treat acne wounds. An adhesive ring is provided at the outer edge of the bottom of the hydrocolloid base layer, and the adhesive ring provides sufficient adhesion to firmly adhere the acne patch to the skin without causing skin irritation or allergies.

[0010] Preferably, a protective layer is provided on the top of the hydrocolloid base layer, and the protective layer is made of polyurethane material. The protective layer is intended to protect the acne patch from external pollution and physical damage, while ensuring air permeability to provide a comfortable treatment environment for the skin.

[0011] Preferably, the marker signal is a reversible pH-responsive dye, and the reversible pH-responsive dye is anthocyanin, which is a safe, non-toxic dye of natural origin that can change color according to changes in pH value, providing users with an intuitive indication of the degree of acne inflammation, thereby understanding the progress of treatment;

[0012] When not in contact with acne secretions, the reversible pH-responsive dye filled in the micropores presents an original color, such as light yellow, indicating that treatment has not been started or the acne area is within the normal skin pH range;

[0013] When the acne patch comes into contact with acne secretions, the anthocyanin will change color according to the change in pH value, as the pH value of the acne inflamed area is usually more acidic. In the initial contact with acne secretions, if the pH value is low, the anthocyanin may turn pink or red, indicating a strong inflammatory reaction in the acne area. At this time, the color change provides an immediate and intuitive indication of inflammation.

[0014] As treatment progresses, skin inflammation gradually subsides and the pH value gradually returns to a more neutral state. At this time, the color of anthocyanins will also change accordingly, gradually transitioning from red or pink to lavender or blue, and finally returning to a light yellow color close to the original. This color transition not only reflects the reduction of acne inflammation, but also indicates that treatment is making progress.

[0015] It is worth noting that the color changes of anthocyanins can provide users with clear visual feedback, allowing them to easily monitor the treatment process and adjust treatment strategies or timing. Through such a design, the acne patch not only has a therapeutic effect, but also enhances user interactivity and improves the treatment experience.

[0016] Preferably, the drug layer is a combination of salicylic acid and sulfur, which can effectively fight acne, reduce inflammation, and accelerate skin recovery.

[0017] Preferably, a release paper is bonded to the bottom of the adhesive ring to protect the adhesive ring from being contaminated before use.

[0018] Preferably, a protrusion is provided on the release paper to facilitate the user to tear the release paper from the adhesive ring.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. This hydrocolloid acne patch with drug coating area marking signal can provide immediate and intuitive treatment feedback with the help of reversible pH responsive dye. Users can directly observe the changes in the degree of acne inflammation through color changes, thereby understanding the progress of treatment and increasing their sense of participation and confidence in treatment.

[0021] 2. The hydrocolloid acne patch with drug coating area marking signal, the good air permeability and moisture absorption of the hydrocolloid base layer helps to effectively absorb wound secretions, reduce the possibility of microbial growth, and provide a more suitable healing environment for the wound.

[0022] 3. The hydrocolloid acne patch with drug coating area marking signal, the salicylic acid and sulfur composition in the drug layer has excellent anti-acne ability, can effectively reduce inflammation and accelerate the skin's recovery process.

[0023] 4. The hydrocolloid acne patch with drug coating area marking signal has an adhesive ring that provides sufficient adhesion to ensure that the acne patch can be firmly adhered to the skin. At the same time, the design ensures that it will not cause irritation or allergic reactions to the skin and is suitable for all types of skin.

[0024] 5. The hydrocolloid acne patch with drug coating area marking signal has a polyurethane protective layer on the top to protect the acne patch from external pollution and physical damage, while ensuring breathability to provide a comfortable treatment environment for the skin.

[0031] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0032] A hydrocolloid acne patch with a marking signal of a drug coating area comprises a hydrocolloid base layer 1. The hydrocolloid base layer 1 has good air permeability and hygroscopicity, can effectively absorb wound secretions, reduce the possibility of microbial growth, and promote wound healing. The hydrocolloid base layer 1 is provided with a plurality of micropores 10, and the micropores 10 are filled with marking signal substances 4. The marking signal substances 4 can contact with wound secretions and produce color changes, thereby providing users with an intuitive indication of the degree of acne inflammation. A drug layer 3 is provided in the middle of the bottom of the hydrocolloid base layer 1, and the drug layer 3 is used to treat acne wounds. An adhesive ring 5 is provided at the outer edge of the bottom of the hydrocolloid base layer 1, and the adhesive ring 5 provides sufficient adhesion to firmly adhere the acne patch to the skin without causing skin irritation or allergies.

[0033] In this embodiment, a protective layer 2 is provided on the top of the hydrocolloid base layer 1. The protective layer 2 is made of polyurethane material. The protective layer 2 is intended to protect the acne patch from external pollution and physical damage, while ensuring air permeability to provide a comfortable treatment environment for the skin.

[0034] Specifically, the marker signal 4 is a reversible pH-responsive dye, and the reversible pH-responsive dye uses anthocyanin, which is a safe, non-toxic natural dye that can change color according to changes in pH value, providing users with a visual indication of the degree of acne inflammation, thereby understanding the progress of treatment;

[0035] When not in contact with acne secretions, the reversible pH-responsive dye filled in the micropores 10 presents an original color, such as light yellow, indicating that treatment has not been started or the acne area is within the normal skin pH range;

[0036] When the acne patch comes into contact with acne secretions, the anthocyanin will change color according to the change in pH value, as the pH value of the acne inflamed area is usually more acidic. In the initial contact with acne secretions, if the pH value is low, the anthocyanin may turn pink or red, indicating a strong inflammatory reaction in the acne area. At this time, the color change provides an immediate and intuitive indication of inflammation.

[0037] As treatment progresses, skin inflammation gradually subsides and the pH value gradually returns to a more neutral state. At this time, the color of anthocyanins will also change accordingly, gradually transitioning from red or pink to lavender or blue, and finally returning to a light yellow color close to the original. This color transition not only reflects the reduction of acne inflammation, but also indicates that treatment is making progress.

[0038] It is worth noting that the color changes of anthocyanins can provide users with clear visual feedback, allowing them to easily monitor the treatment process and adjust treatment strategies or timing. Through such a design, the acne patch not only has a therapeutic effect, but also enhances user interactivity and improves the treatment experience.

[0039] Furthermore, drug layer 3 is a composition of salicylic acid and sulfur, which two ingredients can effectively fight acne, reduce inflammation, and accelerate skin recovery.

[0040] Furthermore, a release paper 6 is bonded to the bottom of the adhesive ring 5 to protect the adhesive ring 5 from being contaminated before use.

[0041] Furthermore, a protruding piece 60 is provided on the release paper 6 to facilitate the user to tear the release paper 6 from the adhesive ring 5 .

[0042] When the hydrocolloid acne patch with a drug coating area marking signal of this embodiment is used:

[0043] 1. Prepare the skin: First, clean and thoroughly dry the acne and the skin area around it, making sure there is no oil or other skin care product residue;

[0044] 2. Tear off the release paper 6: Use the protrusion 60 on the release paper 6 to easily tear off the release paper 6 to expose the adhesive ring 5;

[0045] 3. Apply the acne patch: Align the drug layer 3 in the acne patch to the acne area and gently stick it to the skin surface, ensuring that the adhesive ring 5 is in good contact with the skin;

[0046] 4. Observe changes: During use, pay attention to the color changes of the marker signal substance 4 (anthocyanin) in the micropores 10 of the acne patch. This will help you understand the degree of inflammation and the progress of treatment. When the color gradually changes from light yellow to pink or red, it means that there is a strong inflammatory reaction in the acne area. Then the color gradually returns to light yellow, indicating that the acne inflammation is alleviated and the skin is gradually recovering.

[0047] 5. Replace the acne patch: According to the degree of inflammation of the acne, replace the acne patch in time to continue the treatment and keep the skin clean and hygienic;

[0048] 6. Completion of treatment: When the acne is completely healed and there is no new color change, you can stop using the acne patch.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
