Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical supplies, and more specifically, to a scar patch with UV protection function. Background Art
[0002] After burns, trauma or surgery, the use of silicone gel scar patches to promote wound healing and reduce scar formation has become a common method. Silicone gel scar patches are generally composed of a backing layer, a silicone gel layer, and a release layer. The principle of scar patches to prevent scar formation is that silicone gel reduces the evaporation of skin moisture at the scar site, avoiding the dehydration of keratinocytes to release cytokines that stimulate fibroblasts to produce too much collagen to form scars; small molecule silicone oil in silicone gel seeps out and forms hydrated collagen with collagen at the scar site, making the scar site softer and lighter in color; the pressure of the scar patch on the skin blocks the excessive growth of collagen fibers and prevents hypertrophic scars.
[0003] Some existing scar stickers do not have UV protection capabilities, and the newly grown skin at the scar has weak UV protection capabilities. If no UV protection is provided, UV rays will damage newly grown fibroblasts and epithelial cells, affecting collagen synthesis and causing scars to heal slowly. On the other hand, in order to resist damage, skin cells will produce a large amount of melanin, causing the scar to darken in color, affecting the fading of the scar.
[0004] In order to solve the above problems, the present application provides a scar patch with UV protection function. Utility Model Content

[0007] Furthermore, cotton layers are symmetrically arranged on both sides of the silicone gel layer, and the bottom end of the cotton layer is arranged on the top end of the release layer.
[0008] Through the above technical solution, the cotton layer is provided to wipe and clean the adhesive residue remaining after the scar patch is torn off.

[0027] Example:
[0028] The present application discloses a scar patch with UV protection function. Figure 1 , Figure 2 and Figure 3 , including a release layer 1, a silicone gel layer 8 is arranged on the top of the release layer 1, a UV shielding agent 9 is arranged inside the silicone gel layer 8, a backing layer 7 is arranged on the top of the silicone gel layer 8, a UV absorber 10 and a UV shielding agent 9 are arranged inside the backing layer 7, a sleeve film 2 is arranged on the outside of the silicone gel layer 8, and a top mold 3 is arranged on the top of the sleeve film 2.
[0029] The material of the backing layer 7 can be selected from silicone mesh, polyurethane film, PE film, etc., and ultraviolet blockers are added to the backing layer 7 material or the silicone gel layer 8 to increase the anti-ultraviolet function of the scar patch; the ultraviolet blockers include ultraviolet shielding agents 9 and ultraviolet absorbers 10. The ultraviolet shielding agents 9 can block or reflect ultraviolet rays so that light cannot penetrate into the interior of the material, thereby playing a role in ultraviolet protection. Commonly used ultraviolet shielding agents 9 include inorganic substances such as carbon black, titanium dioxide, zinc oxide, and nano-silicon dioxide; the ultraviolet absorbers 10 can absorb ultraviolet light and convert it into heat energy to dissipate, thereby playing a role in ultraviolet protection. Common ultraviolet absorbers 10 include o-hydroxybenzophenone, benzotriazole, salicylate, triazine, substituted acrylonitrile, etc.
[0030] The backing layer 7 does not come into direct contact with the scarred skin, and can be used in conjunction with the ultraviolet shielding agent 9 and the ultraviolet absorber 10 to achieve a better ultraviolet protection effect. The ultraviolet absorber 10 has the characteristics of easy migration and strong irritation, and the amount added to the product does not exceed 5%. The material of the backing layer 7 can be selected from polyurethane film, silicone mesh film, non-woven fabric, etc., and the thickness of the selected material is between 0.1mm and 1mm.
[0031] The silicone gel layer 8 is in direct contact with the scar, and the skin at the scar is relatively fragile, so a UV shielding agent 9 with good stability and low irritation is selected to achieve the sun protection function. 1% to 10% of nano-scale titanium dioxide and zinc oxide particles are added to the silicone gel layer 8 to achieve the product's UV blocking function. The particle size specification of the selected nano-scale particles is between 10nm and 100nm.
[0032] The release layer 1 is mainly release paper or release film. The release paper can be glassine, CCK, PEK, etc., and its grammage per square meter is between 40g / ㎡ and 150g / ㎡. The release film can be PET release film, PP release film or PE release film, etc., and the film thickness is between 15μm and 100μm, and is mainly used for covering and protecting the silicone gel layer 8.
[0033] See also Figure 1 , Figure 2 and Figure 3 Cotton layers 4 are symmetrically arranged on both sides of the silicone gel layer 8 , and the bottom end of the cotton layer 4 is arranged on the top end of the release layer 1 .
[0034] The cotton layer 4 is made of medical absorbent cotton and is used to wipe and clean the adhesive residue left after the scar patch is torn off.
[0035] See also Figure 1 , Figure 2 and Figure 3 A cavity is provided inside the cotton layer 4, and a film 11 is provided inside the cavity.
[0036] Here, the film 11 is made of polyethylene plastic, which can wrap the alcohol inside and prevent it from being decomposed. By setting the film 11, it is used to wrap the filling liquid 12 and place it inside the cotton layer 4 for easy storage.
[0037] See also Figure 1 , Figure 2 and Figure 3 A filling cavity is provided inside the film 11 , and a filling liquid 12 is provided inside the film 11 .
[0038] The filling liquid 12 here is alcohol, and the viscose 5 is easily soluble in alcohol. By setting the filling liquid 12, it is used to dissolve the adhesive remaining after the scar patch is torn off, so as to facilitate wiping. After the scar patch is torn off, the cotton layer 4 is pressed first to apply pressure to the film 11 to break it, and then the alcohol inside flows out and is absorbed by the cotton layer 4. Then, the cotton layer 4 is held and the adhesive on the scar is wiped.
[0039] See also Figure 1 , Figure 2 and Figure 3 The bottom end of the release layer 1 is symmetrically provided with adhesive 5 , and the bottom end of the adhesive 5 is provided with a sticker 6 .
[0040] After the sticker 6 is torn off, the scar sticker can be attached to the scar of the user through the adhesive 5.
[0041] The implementation principle of this embodiment is: when in use, the sticker 6 is torn off first, and then the release layer 1 is attached to the skin around the scar through the adhesive 5, and the silicone gel layer 8 is placed on the top of the scar.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
