Abstract

The invention discloses a medical cold compress plaster which comprises a backing layer, a gel layer and a covering layer connected in sequence from top to bottom, wherein the raw materials of the medical gel layer comprise the following components: propylene glycol, glycerin, 1,3-butanediol, sodium hyaluronate, glyceryl polyether-26, verbena extract, trehalose, Carbomer, gentina root extract, Chinese eaglewood extract and water. The medical cold compress plaster disclosed by the invention is convenient to use, harmless to a human body, non-irritating and zero in side effect, can also be usedeven if skin is broken, has a moisturizing effect, can be used for maintenance after micro-plastic surgery, is capable of helping to maintain the damaged skin after spot and mole removal, has an excellent effect on skin disease red swelling, is capable of calming the skin, can be used before makeup, and also has effects of repairing dry skin and the like. Moreover, the effect achieved by the coldcompress plaster disclosed by the invention is a synergistic effect among the verbena extract, gentina root extract and Chinese eaglewood extract.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a medical cold compress and a preparation method thereof. Background technique [0002] The cold compress is improved according to the traditional cold compress method. The TDDS new drug release system prepared on the basis of polymer gel is the core. It is composed of a backing layer, a gel layer and a covering layer. Through the moisture contained in the polymer gel The gasification of natural cooling ingredients can take away heat, which can achieve local cooling. The drug in it is combined with hydrogel, and through hydration, the drug ingredients can quickly penetrate the fat layer, penetrate into the subcutaneous tissue, and reach the lesion. Act on the affected area to achieve the effects of cold compress, percutaneous absorption and sustained release of drugs. [0003] Cold compresses can promote local capillary contraction, reduce local congestion, ...
