Description

Technical Field

[0001] This utility model relates to the field of scar care patches, and more particularly to a scar care patch with an array of breathable holes. Background Technology

[0002] Scar care dressings are medical dressings widely used in postoperative repair, burn healing, and scar management. Their core functions are to provide continuous drug treatment, maintain a moist wound environment, and promote tissue repair. Traditional scar care dressings typically employ a closed structure, using a drug-releasing layer and an adhesive layer to cover and protect the scar area. However, with increasing clinical demands, enhancing breathability and reducing local moisture accumulation while ensuring effective drug penetration has become a key direction for current technological development.

[0003] Existing scar care patches mostly employ single-layer or multi-layer composite structures, including a drug-releasing layer, an adhesive layer, and a waterproof base layer. The drug layer is typically composed of a hydrogel or silicone matrix, with the drug components loaded through physical mixing or microencapsulation technology. The adhesive layer uses medical pressure-sensitive adhesive to achieve adhesion to the skin; some products increase the thickness of the adhesive layer to enhance adhesion. The base layer is mostly a polyurethane or polyethylene film, used to block external pollutants. Regarding breathability design, existing technologies mainly achieve this through two methods: one is to incorporate hydrophilic particles or microporous structures into the substrate, utilizing the material's inherent breathability; the other is to create sparse ventilation channels through localized perforation or laser engraving. However, the channel distribution is usually relatively simple, lacking targeted optimization for gas and liquid flow.

[0004] While existing scar care patches offer basic drug release and wound protection, their breathability remains significantly insufficient. Because most products rely on a sealed structure or a sparsely perforated design, prolonged use can lead to local moisture buildup, causing skin maceration, allergies, and hindering effective drug penetration, thus reducing scar repair results.

The large holes are rectangular and are located inside the breathable layer. The small holes are arranged in a ring array inside the breathable layer. A base layer, wherein a hydrophobic groove is formed inside the base layer, and the hydrophobic groove is formed in a linear array inside the base layer.

[0007] As a further description of the above technical solution: A protective layer is provided on top of the base layer, and the bottom of the protective layer is adhesively bonded to the top of the base layer. The protective layer is used to block dust.

[0008] As a further description of the above technical solution: A drug layer is fixedly connected to the bottom of the base layer, and a flow hole is formed inside the drug layer. The bottom of the flow hole is located at the top of the breathable layer.

[0009] As a further description of the above technical solution: The breathable layer has small and large holes inside, and the tops of the small and large holes are located at the bottom of the drug layer.

[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, 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.

[0016] Reference Figures 1-3 One embodiment of this utility model is a scar care patch with an array of breathable holes, comprising: Drug layer 4 has honeycomb-shaped slots 401 and flow holes 402 inside. The honeycomb-shaped slots 401 are used to provide uniform drug storage space, and together with the flow holes 402, they realize the directional flow and sustained release of the drug, so as to achieve the effect of continuous and uniform penetration into the scar area. The honeycomb-shaped slots 401 are uniformly opened in a honeycomb pattern inside the drug layer 4. The flow holes 402 are opened inside the honeycomb plate to promote drug flow. The details are not elaborated here. The flow holes 402 are all opened inside the honeycomb plate. The breathable layer 5 has small holes 501 and large holes 502 inside. The small holes 501 are distributed in a ring array to improve gas exchange efficiency and form a gradient breathable structure with the large holes 502. The large holes 502 are arranged in a rectangular layout to expand the breathable area, which together reduces the accumulation of moisture. The top of the small holes 501 and the large holes 502 are located at the bottom of the drug layer 4. The large holes 502 are rectangular and are opened inside the breathable layer 5. The small holes 501 are arranged in a ring array inside the breathable layer 5. A base layer 3 has hydrophobic grooves 301 inside, which are used to quickly guide liquid. These grooves are arranged in a linear array to prevent localized dampness. A protective layer 1, composed of release paper / film, is placed on top of the base layer 3 to provide dust protection (this is existing technology). The bottom of the protective layer 1 is adhesively bonded to the top of the base layer 3 to block dust. A drug layer 4 is fixedly connected to the bottom of the base layer 3. Flow holes 402 are formed inside the drug layer 4. 2. The bottom is set on top of the breathable layer 5. The breathable layer 5 has small holes 501 and large holes 502 inside. The tops of the small holes 501 and large holes 502 are set at the bottom of the drug layer 4. The outer wall of the breathable layer 5 is fixedly connected to the adhesive layer 2. The adhesive layer 201 is fixedly connected inside the adhesive layer 2. The adhesive layer 201 uses medical acrylic pressure-sensitive adhesive and is used for skin adhesion. It is a conventional material for scar patches. The bottom of the adhesive layer 201 is fixedly connected to multiple convex balls 202. The outer wall of the adhesive layer 201 is fixedly connected to the skin layer 203, which is used to adhere to the skin.

[0017] Working principle: The honeycomb grooves 401 in the drug layer 4 provide a uniform drug storage space, while the flow holes 402 promote the directional flow and sustained release of the drug, ensuring that the drug can continuously and evenly penetrate into the scar area. The small pores 501 and large pores 502 in the breathable layer 5 form a gradient breathable structure. The small pores 501 improve gas exchange efficiency through a ring array distribution, while the large pores 502 further expand the breathable area with a rectangular layout, thereby effectively reducing moisture accumulation. The hydrophobic grooves 301 in the base layer 3 can quickly drain liquid, avoid local moisture, and reduce the time that liquid remains on the surface of the scar patch. The adhesive layer 2, with its adhesive patch 201 and raised balls 202, ensures a good fit while creating micro-breathable channels through the gaps between the raised balls 202, further enhancing overall breathability. The skin-adhesive layer 203 adheres closely to the skin, reducing friction and discomfort, while the protective layer 1 prevents dust and contaminants from entering, extending the usage time. This solves the problem of insufficient breathability in traditional scar care patches and significantly improves scar repair effects and user comfort by optimizing drug release and liquid management.
