26 results about "Hydrocolloid dressing" patented technology

A hydrocolloid dressing is an opaque or transparent dressing for wounds. A hydrocolloid dressing is biodegradeable, breathable, and adheres to the skin, so no separate taping is needed. The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxymethyl cellulose together with other polymers and adhesives forming a flexible wafer. In contact with wound exudate, the polysaccharides and other polymers absorb water and swell, forming a gel. The gel may be designed to drain, or to remain within the structure of the adhesive matrix.
