AI Technical Summary
Existing hydrocolloid dressings have poor breathability, which makes it difficult to drain large amounts of exudate from the wound in a timely manner, easily causing skin edema.
A wound surface liquid hydrocolloid dressing was designed, comprising a main release paper, a hydrocolloid layer, a hydrocolloid perforated layer, an alginate layer, and a backing layer. The alginate layer is connected to the hydrocolloid perforated layer through alginate cylinders to form a structure with good air permeability and the ability to isolate bacteria. When the amount of exudate is large, the high hygroscopicity of alginate can absorb excess fluid.
This invention achieves a solution that avoids skin swelling by eliminating the need for a breathable and bacteria-isolated structure, without compromising the design of the existing technology.
