ABSTRACT:

BACKGROUND
1. Technical Field
The present invention relates to a medical compress for the treatment of wounds in a wet or humid environment.
2. Background of Related Art
Wounds which do not heal with customary medical measures are termed chronic wounds. Frequently their development is promoted by various systemic diseases (diabetes mellitus and other metabolic disorders, arterial and venous vascular disorders, cardiac and circulatory disorders etc.)
The spread of germs and necroses favors the chronicity of the wounds. A possible cause for the progression of chronic wounds is the infiltration of necrotic of bacterial or other toxins into the surrounding tissues.
Every therapeutic concept for chronic wounds has the aim to support the self-healing power of the wound. In the first place, apart from treatment of the underlying disease and the exclusion of disturbing influences, the wound must be cleansed from necroses and toxins. In addition to surgical interventions (debridement) wet treatment with wet dressings has for decades taken the foremost place. Wet dressings usually imply in-hospital treatment of the patient, which considerably limits the realization of this therapy.
For spontaneous healing of a wound the most important substances required are proteins, lipids, vitamins and oxygen. If the supply of these substances is disturbed, the wound has a tendency to become chronic. In addition a number of external factors can delay spontaneous wound healing or make it impossible in this respect infections, but also excessive cooling or drying of the wound play a decisive part.
Growth factors play an important role as messengers for regulating almost all processes of wound healing. Cytokines are produced and released by a variety of cells and act on a variety of cell populations participating in wound healing.
In necrotic tissue toxins are liberated which infiltrate into the surrounding intact tissues. Thus, wound healing is impaired. If, for example, monocytes or macrophages are missing, the defense of infections becomes impossible. Blood vessels and nerve endings degenerate and recede. The result is progression of necrosis which can as a rule only be stopped with surgical debridement.
European Patent Publication EP 0,594,034 discloses a medical compress for treatment of wounds which includes a soakable body of superabsorbent material arranged in an outer cover layer. The compress is plastically deformable and can be formed into the profile of a wound. This publication is incorporated by reference herein.
A problem observed with superabsorbent materials formed into a fine textured, tight, laminate structure made from fabrics such as cellulose is gel blocking. Gel blocking occurs when gel formed in one region of the superabsorbent material physically interferes with absorption of fluid in a next region, thereby reducing absorption efficiency.
SUMMARY
A compress for the treatment of wounds is provided herein. The compress includes a non-woven textile fabricated from air-laid fibers containing a superabsorbent material and a cover for enclosing the non-woven textile. Optionally, a medical wound irrigating solution is contained in the medical compress.
The compress advantageously facilitates the healing of chronic wounds while providing improved comfort for the patient.
