Abstract
The invention provides a sodium hyaluronate dressing containing icodextrin. The sodium hyaluronate dressing comprises the following components in parts by mass: 0.008-0.05% of icodextrin, 0.05-0.1% ofsodium hyaluronate, 3-6% of propylene glycol, 0.02-0.1% of chlorophenyl glycol, 0.3-0.5% of phenoxyethanol, 0.1-0.5% of ethylhexyl glycerin, 0.3-0.5% of 1,2-hexanediol, 93-95% of purified water or water for injection, and 0.001-0.005% of flavoring agent. The dressing of the present invention has a good moisturizing and repairing effect, can be made into a form of original liquid + gauze/non-wovenfabric, has good nutrition and lubrication effect on skin, and especially can make damaged skin recover faster, so that the skin is less prone to proliferation or pollution.
Description
technical field [0001] The invention belongs to the field of medical devices, in particular to a sodium hyaluronate dressing containing icodextrin. Background technique [0002] Sodium hyaluronate is a mucopolysaccharide formed by alternately linking glucuronic acid and N-acetylglucosamine as disaccharide units. It is widely found in nerve tissue, skin dermis and other tissues; in organs, it is distributed in the cytoplasm, intercellular substance It lubricates and nourishes the cells and organelles contained therein. [0003] Glucan is a homopolysaccharide composed of glucose as a monosaccharide, which is divided into α-glucan and β-glucan, and each glucan has a variety of bond combinations. As an active ingredient in skin care products, dextran has a long history in the West. Families in many European and American countries are used to bathing infants and young children with water soaked in oatmeal to relieve and prevent eczema; the elderly are also used to washing their...
