Method for preparing Porous Collagen, application in the treatment and care of the skin

摘要

When there has been loss of skin, e.g. owing to burns, collagen material has proved advantageous as temporary skin replacement instead of transplants. A collagen skin dressing material which is in sheet form and suitable for rapid use is produced by forming a collagen gel, extruding the collagen gel and forming a collagen sheet from the extruded gel. The collagen is then crosslinked, for example by treatment with glutaraldehyde. The crosslinked sheet is subsequently freeze-dried, and the freeze-drying can be preceded by partial air-drying. Bactericidal agents or antibiotics can be added to the gel or to the collagen sheet.
