Multifunctional microstructure patch
View Patent ↗A multifunctional microstructure patch is provided. The multifunctional microstructure patch, according to one embodiment of the present invention, comprises: a base layer having an opening part formed in the center thereof; a plurality of microstructures formed on one surface of the base layer and comprising a first drug; and a cover layer detachably bonded on the other surface of the base layer along the periphery of the opening part, and formed so as to cover the opening part.
1. A multifunctional microstructure patch comprising:
a base layer having an opening part;
a plurality of microstructures formed on one surface of the base layer and including a first drug;
a cover layer detachably bonded to the other surface of the base layer along a periphery of the opening part and formed so as to cover the opening part; and
a protective layer bonded to a surface of the cover layer facing the base layer and having a size smaller than or equal to that of the opening part.
2. The multifunctional microstructure patch of claim 1 , wherein at least a portion of the cover layer is configured to be separated from the base layer.
3. The multifunctional microstructure patch of claim 2 , wherein the cover layer is configured to be re-bonded to the base layer.
4. The multifunctional microstructure patch of claim 1 , wherein the first drug includes a local anesthetic selected from the group consisting of cocaine, procaine, chloroprocaine hydrochloride, tetracaine, dibucaine, lidocaine, mepivacaine, benzocaine, bupivacaine, and a combination thereof.
5. The multifunctional microstructure patch of claim 4 , wherein the local anesthetic is comprised on a surface of the microstructure or embedded in the microstructure.
6. The multifunctional microstructure patch of claim 1 , wherein the cover layer includes a peeling portion protruding from a portion of an outer periphery and the peeling portion is not coated with an adhesive.
7. The multifunctional microstructure patch of claim 1 , wherein the cover layer includes an adhesive portion comprising an adhesive, wherein the adhesive is comprised along a periphery of the protective layer.
8. The multifunctional microstructure patch of claim 1 , wherein an adhesive is comprised on one surface of the base layer.
9. The multifunctional microstructure patch of claim 1 , wherein the protective layer includes cotton or gauze.
10. The multifunctional microstructure patch of claim 1 , wherein the protective layer includes a disinfectant.
11. The multifunctional microstructure patch of claim 10 , wherein the disinfectant includes ethanol or isopropyl alcohol.
12. The multifunctional microstructure patch of claim 1 , wherein the first drug includes a biocompatible material or a biodegradable material.
13. The multifunctional microstructure patch of claim 1 , further comprising:
a second base layer configured to be attached to skin in the opening part; and
a plurality of second microstructures comprised on one surface of the second base layer and including a second drug different from the first drug.
14. The multifunctional microstructure patch of claim 13 , wherein the cover layer includes an adhesive portion comprising an adhesive, wherein the adhesive is comprised along a periphery of the opening part.
15. The multifunctional microstructure patch of claim 13 , wherein the second base layer is larger than the opening part, and the second microstructure is disposed in the opening part.
16. The multifunctional microstructure patch of claim 13 , wherein the second base layer is smaller than or equal to the opening part.
17. The multifunctional microstructure patch of claim 13 , wherein the first drug and second drug include a biocompatible material or a biodegradable material.
18. The multifunctional microstructure patch of claim 1 , where the opening part is comprised at a center of the base layer, wherein the opening comprises a “C” or “⊂” shape a circular shape, an elliptical shape, a curved shape, or a polygonal shape.
