The invention belongs to the technical field of medical dressings, and particularly relates to a sunken scar repair dressing and a preparation method thereof. The concave scar repair dressing comprises a hydrophilic fiber layer, a hydrophobic barrier layer and a biological active layer which are sequentially arranged from the side in contact with a wound surface to the outside, the hydrophobic barrier layer is partially combined on the surface of the hydrophilic fiber layer in a physical embedding manner, and the bioactive layer is fixed on the outer side of the hydrophobic barrier layer in a chemical crosslinking manner; the hydrophilic fiber layer is composed of polyvinyl alcohol / hyaluronic acid composite fibers prepared through electrostatic spinning. The three-layer structure of the dressing simulates partial functional gradient of the skin, covers hydrophilic absorption, barrier protection and active repair, and better meets physiological repair requirements. According to the invention, interlayer combination is realized through two mechanisms of physical embedding and chemical crosslinking, so that the integrity and durability of the dressing are remarkably improved, and layering during use is avoided.

The invention relates to the technical field of medical dressings, in particular to a scar repair silicone gel and a preparation method thereof. The scar repairing silicone gel is prepared from the following components in percentage by mass: 10 to 20 percent of decamethylcyclopentasiloxane, 6 to 10 percent of organic silicon polymer, 2 to 7 percent of simethicone, 3 to 5 percent of functional additive, 0.3 to 0.6 percent of hydroxyethyl cellulose, 1 to 3 percent of glyceryl monostearate, 3 to 8 percent of glyceryl stearate, 1.5 to 2 percent of fumaric acid, 0.2 to 0.6 percent of ethylhexylglycerin and the balance of water. The linear polymethylhydrosiloxane is crosslinked to form a compact elastic three-dimensional network, so that the silicone film has excellent air permeability and mechanical properties; the functional auxiliary agent realizes dual repair of physical closed moisturizing and biological activity promotion, and is beneficial to repair of scars; the silicone gel prepared by the invention not only can efficiently repair scars, but also has excellent antibacterial property, mechanical property and biocompatibility, and the whole system does not contain irritant components and is suitable for sensitive skin.

The invention provides an external composition for reducing and repairing striae gravidarum and scars as well as gel and application of the external composition, and relates to the field of scar repair. The external composition is prepared from the following raw materials in parts by weight: 23 to 28 parts of herba lysimachiae, 15 to 25 parts of pine nodular branch, 10 to 20 parts of radix rehmanniae preparata, 7 to 12 parts of caulis sargentodoxae, 5 to 10 parts of rhizoma polygonati and 3 to 8 parts of folium artemisiae argyi. The preparation method comprises the following steps: S1, selecting traditional Chinese medicinal materials of radix rehmanniae preparata, rhizoma polygonati and folium artemisiae argyi, adding 8-12 times by weight of water, decocting, filtering to obtain a decoction, and concentrating to obtain a composition I; s2, selecting traditional Chinese medicinal materials such as Sargentodoxa cuneata, sargentgloryvine stem and pine nodular branch, extracting by using 70-75% v / v ethanol solution at the extraction temperature of 50-60 DEG C to obtain extract liquid, and concentrating to obtain a composition II; s3, mixing the composition I in the step S1 and the composition II in the step S2 to obtain the target composition. The traditional Chinese medicine composition has a synergistic effect, has a remarkable curative effect on reducing and repairing striae gravidarum and scars, is good in safety and can be applied to preparation of products for reducing and repairing striae gravidarum and scars.
