Example 1

[0032] The present invention provides a hydrogel surgical dressing 1 having a multi-dimensional flexible hydrophilic structure-linkage composite 10, as shown in FIG. 1, comprising: a hydrogel cushion layer 20, and a multi-dimensional flexible hydrophilic structure-linkage composite, wherein said multi-dimensional flexible hydrophilic structure-linkage composite 10 comprising a hydrophilic multi-dimensional flexible structure-linkage membrane 13, and a multiple of structure-linkage holes 15 positioned into said hydrophilic multi-dimensional flexible structure-linkage membrane 13, and the sizes of structure-linkage holes 15 change with the degree of compelling force, resulting in a multi-dimensional flexible structure-linkage relationship. Said hydrogel cushion layer 20 comprising a multiple of hydrophilic structure-linkage fibers 23 and a multiple of hydrogel micro balls 25, said hydrophilic structure-linkage fiber 23 adsorbs side by side with said hydrogel micro ball in said hydrogel cushion layer 20; and said hydrogel cushion layer 20 is supported by a hydrophilic structure-linkage network forming through a network connection among said hydrophilic structure-linkage fibers 23 and said hydrophilic structure-linkage fibers 23, wherein said network connection comprising a first partial connection occurring into said structure-linkage holes 15, a second partial connection surrounding said structure-linkage holes 15, and a third connection linking said first partial connection and said second partial connection to form said multi-dimensional flexible structure-linkage relationship. Said hydrogel cushion layer comprises a multiple of hydrophilic microsphere 30 positioned in said hydrogel cushion layer 20, wherein said hydrophilic microsphere 30 adsorbs side by side with said hydrogel micro ball 25, and adsorbs side by side with said hydrophilic structure-linkage fiber 23, resulting in a consolidated structure of said hydrogel cushion layer 20. Because of the structure prepared from at least two kinds of polymeric network, the hydrophilic structure-linkage network preferably belongs to a kind of interpenetrating polymeric network or semi-interpenetrating polymer network. In the specific application, said hydrophilic microsphere 30 could be movably in said hydrophilic structure-linkage network. The mobility and efficiency of said hydrophilic microsphere 30 could be controlled by the size of said hydrophilic structure-linkage network. Preferably, said hydrophilic structure-linkage fiber 23 comprising a material selected from a group of polymethacrylate, polymethacrylate derivative, polysiloxane derivative, carboxymethylcellulose, alginate, polycarbohydrate, hyaluronic acid, collagen, vegetative protein, gelatin, polylactides, polyethylene pyrrole, polyethylene glycol, and thereof. Preferably, said hydrogel micro ball 25 comprising a material selected from a group of polymethacrylate, polymethacrylate derivative, polysiloxane derivative, carboxymethylcellulose, alginate, polycarbohydrate, hyaluronic acid, collagen, vegetative protein, gelatin, polylactides, polyethylene pyrrole, polyethylene glycol, and thereof. Preferably, said hydrophilic microspherel 30 comprising a material selected from a group of amino acid, water, oxygen, ethyl alcohol, propyl alcohol, glycerine, small molecular water-soluble polymethyl acrylic acid derivative, small molecular polysiloxane derivative, small molecular carboxymethylcellulose, small molecular alginate, small member carbohydrate, small molecular Bolivian uric acid, small molecular collagen, small molecular vegetative protein, small molecular gelatin, small molecular polylactate, small molecular polyethylene pyrrole, small molecular polyethylene glycol, peptide and thereof. Preferably, said structure-linkage holes are round. Preferably, this multi-dimensional flexible hydrophilic structure-linkage composite 10 was prepared from materials chosen from the combination of one of the groups of polyvinyl-chloride, polyethylene, ethylene vinyl acetate copolymer, polyvinyl alcohol, polyurethane, polypropylene or polyethylene, Teflon (PTFE), polysiloxane, polylactate derivatives, water-soluble polymethacrylic acid derivatives, cellulose derivatives, chitosan derivatives, carbon fiber derivatives and thereof. Particularly, the hydrogel surgical dressing 1 having a multi-dimensional flexible hydrophilic structure-linkage composite 10 is employed in clinical applications (see FIG. 2), the hydrogel surgical dressing 1 would contact with a target wound 1000. A multiple dimension flexible protecting film would be employed with said hydrogel surgical dressing 1 to fix said hydrogel surgical dressing 1 to cover said target wound 1000. At the same time, said multiple dimension flexible protecting film has to avoid contact with said target wound 1000. Said hydrophilic microsphere 30 could be movable in said hydrophilic structure-linkage network and employed to carry a nutrient, an enzyme, a growth factor, tissue, metabolite, etc. The mobility and carrying efficiency of said hydrophilic microsphere 30 could be controlled by the size of said hydrophilic structure-linkage network. The present invention provides a designed multi-dimensional flexible hydrophilic structure-linkage module in a hydrogel surgical dressing product to solve the clinical problems of traditional hydrogel dressings, in particular, falling off situation happening after swelling with water or tissue fluid in medical applications. The designed multi-dimensional flexible hydrophilic structure-linkage module provides a multi-dimensional flexible structure-linkage relationship of each parts of said hydrogel surgical dressing 10 instead of the traditional design of multiple adhering layers. The force inducing falling off situation could be dispersing into the multi-dimensional flexible hydrophilic structure-linkage composite. For example, medical treatments of a joint region 2000 was carried out.
