Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] The microneedle patch for treating keloids of the present invention does not contain drugs, and includes a substrate and a microneedle array arranged on the substrate. The microneedle array includes a plurality of microneedles, and the distance between each microneedle is not less than 200 microns. The needle length is between 300-1000 microns, and the microneedle material is non-metal that does not swell and soften in the skin and does not cause skin itching and allergies. Here, the base is set in a flat shape, and may be in other shapes such as circles and rectangles.

[0038]In an embodiment, the microneedles are made of polymers, and the polymers include poly(lactic-co-glycolic acid), PLGA, poly(lactic acid), PLA, polyethylene Lactone (polycaprolactone, PCL), liquid crystal polymer (liquid crystal polymer, LCP), polymethyl methacrylate (poly...

Abstract

The invention relates to a microneedle patch for treating keloid as well as a kit and application. The microneedle patch does not contain medicine, and comprises a substrate and a microneedle array arranged on the substrate, wherein the microneedle array comprises a plurality of microneedles; the gap between each microneedle is not smaller than 200 microns; each microneedle length is 300 to 1000 microns; the microneedle material is nonmetal which cannot generate swelling on the skin, cannot be softened and cannot cause skin itch or irritability. The microneedle patch does not depend on medicine or other bioactive substances for inhibiting the growth of fibrotic lesion; the treatment mode has the cost advantage and has a small side effect.

Description

technical field [0001] The invention specifically relates to a microneedle patch for treating keloids, a kit and application thereof. Background technique [0002] Keloid is a kind of excessive skin reaction to trauma, mainly manifested as excessive proliferation of local fibroblasts and massive synthesis of collagen. The fibrous tissue of a keloid usually extends beyond the extent of the trauma to include surrounding normal tissue. Keloids often recur after surgical removal. Clinically, they are diagnosed as red nodules that cause itching and pain, limit movement, and cause changes in appearance. Keloids usually appear on sebaceous glands or areas of increased skin tension, including the shoulders, upper back and arms, chest, ears, cheeks, and neck. Although they are not life-threatening to patients, they can cause considerable physiological (itching, pain, limitation of movement, etc.) and psychological adverse effects. Keloids are more common in young people aged 20-3...
