Abstract
Liquid loaded pads useful as wound and burn dressings are prepared from pellicles of microbially-produced cellulose obtained, for example, by culturing Acetobacter xylinum. A pellicle having a thickness from about 0.1 to 15 millimeters or greater is processed to replace the culture medium with water or other physiologically compatible liquid. The liquid-loaded pellicle is sterilized prior to its use as a dressing or in other medical applications.
Claims26
A liquid loaded pad for medical applications comprising a fibrous mass of microbially-produced cellulose fibrils and a sterile, physiologically-acceptable liquid retained within the interstices of said fibrous mass, said fibrous mass having a coherent and dimensionally stable structure.
A liquid loaded pad comprising a compressed pellicle of microbially-produced cellulose fibrils and a sterile, physiologically-acceptable liquid retained within the interstices of said compressed pellicle, said pellicle having a coherent and dimensionally stable structure with a thickness of less than about 1 millimeter.
A burn dressing comprising a fibrous mass of microbially-produced cellulose fibrils and a sterile, volatile, physiologically-acceptable liquid retained within the interstices of said fibrous mass, said fibrous mass having a coherent and dimensionally stable structure.
A cold pack for treating burns comprising a fibrous mass of microbially-produced cellulose fibrils, a sterile,physiologically-acceptable liquid retained within the interstices of said fibrous mass, and an insulating backing material on one side of said fibrous mass, said fibrous mass having a coherent and dimensionally stable structure independent of said insulating backing material.
