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 2):
The hydrogel sustained-release paster supporting the heparin sodium according to  claim 1 , wherein the aqueous solution of the hydrogel functional layer comprises the 5%-45% hydrophilic compound by mass, the 0.07%-5% heparin sodium by mass and the 1-5% aqueous transdermal absorbefacient by mass.
