Hydrophilic and hydrophobic agarose collagen dressing

The utility model discloses hydrophilic and hydrophobic agarose collagen dressing which comprises a hydrophilic bracket, a binding layer and a hydrophobic layer, wherein the hydrophilic bracket, the binding layer and the hydrophobic layer are closely integrated into a whole in sequence; the binding layer is an interlayer formed by the staggered and closely integration of the hydrophilic bracket and the hydrophobic layer; the hydrophilic bracket is a composite bracket made of agarose collagen with a three dimensional porous structure and the thickness is 3-4 mm; the hydrophobic layer is made of agarose acetate; the thickness of the dressing is 3.5-4.5 mm; the hydrophobic layer of the hydrophilic and hydrophobic agarose collagen dressing can serve as a shield and maintains a micro-environment for the wound surface skin; as the hydrophilic bracket has hydrophilcity and bioactivity, a favorable remediation environment is provided for the wound surface and the remediation of the wound surface is facilitated; as the function of the dressing is close to the function of the skin, the remediation of the wound surface is accelerated, and the dressing can be applied in the remediation of damaged tissues caused by burning, trauma and surgery incision.
