WOUND DRESSING A sterile sealed flexible package contains a transparent sheet form wound dressing which comprises a wholly synthetic hydrophilic water-insoluble cross-linked polymer swollen with an aqueous liquid. The package is formed by introducing the sheet form polymer and aqueous liquid into the flexible package, sealing the package and then sterilising it in an autoclave in which the temperature and pressure and independently variable. The polymer is usually formed by polymerising ethylenically unsaturated monomers, usually acrylic monomers, e.g. hydroxy alkyl (meth) acrylates and/or (meth) acrylic acid, with copolymerisable ethylenically unsaturated cross-linking agent, and is capable of absorbing at least its own dry weight of 0.9% by weight saline. The swollen polymer gel is used as a wound dressing. |
