Abstract:
The present invention relates to a medical dressing, in particular to a heparin sodium supported hydrogel sustained-release paster. The inventive heparin sodium supported hydrogel sustained-release paster includes a fixing layer and a backing layer and a hydrogel functional layer successively arranged on the fixing layer. The hydrogel functional layer is made up of hydrophilic high-molecular compound, heparin sodium and aqueous transdermal absorbefacient solution to through high-energy ray radiation or freeze-thaw cycle or combination of high-energy ray radiation and freeze-thaw cycle. The invention has the advantages as follows: the flake solid hydrogel material, synthesized by hydrophilic high-molecular compound with high biosecurity, has features of high biosecurity, high moisture content, compact molecular structure, controllable is water loss rate and prolonged service life. In addition, the hydrogel sustained-release paster is easy in operation, convenient to use, timely to remove in case of discomfortable and adverse reaction and free of deteriorated adverse reaction.

Claim (Index 3):
The hydrogel sustained-release paster supporting the heparin sodium according to  claim 2 , wherein the hydrophilic compound is one or more selected from the group consisting of starch, water-soluble cellulose, water-soluble chitosan, agar, carrageenin, arabic gum, pectin, xanthan gum, carrageenan, alginate, hyaluronic acid, gelatin, bone glue, polyglutamic acid, polylysine, fibrous protein, elastin, keratin, polyacrylamide, polyacrylic acid, polyacrylate, polyvinylpyridine, polyvinylpyrrolidone, polyvinyl alcohol, polymaleic anhydride, polyquarternium, polyethylene glycol, polyethylene oxide and polyvinylpyrrolidone in any proportion.
