3. Wounds of sinus tracts and cavities may need to be used with packing dressings such as alginate dressings.
The foam dressing has a soft texture and is close to the wound surface, effectively flattening the raised granulation tissue, and the polymer material does not stimulate granulation proliferation. Rapid expansion after absorbing exudate ensures good contact between the dressings surface and the wound bottom. It has a unique negative pressure drainage effect, ensuring complete contact with the wound surface and rapid drainage.
Absorbs exudate faster, with more volume, anti-reverse osmosis ability, absorbs exudate vertically and locks it tightly in the fixed area, so that the wound maintains a moist environment without impregnating the surrounding skin. This way the dressing can be left in place for several days, making it more cost-effective. The outer layer has a moisturizing film to maintain a moist healing environment and is conducive to wound repair. Absorbency will depend on thickness and composition.
The use of polyurethane foam dressing can isolate external pollution on the skin of the pressure part, protect the exposed nerve endings of the wound, and relieve pain.
In addition, the foam dressing is moderately soft and hard, which can effectively relieve the pressure on the wound surface, reduce the incidence of bedsores in bedridden patients, and play a preventive role. Indicated for pressure injury prevention when used as part of a broader pressure injury prevention protocol.
