Transparent liq. gels e.g. of hydrophilic acrylic! polymer and gelatin - useful as wound dressings, esp. for burns and ulcers, and as cell culture media

TLDR: Transparent dressing as mentioned in this paper consists of a hydrophilic organic transparent gel in sheet or tape form, swollen with an aq. soln. The dressing may be reinforced with a string or net-like reinforcing agent.

Abstract: Transparent liq. dressing, esp. for wounds, comprises a hydrophilic organic transparent gel in sheet or tape form, swollen with an aq. soln. The dressing may be reinforced with a string or net-like reinforcing agent. The aq. soln. used to swell the gel may contain buffers, wound treatment agents, nutrients and/or growth agents. Healing progress of the wound visually without removing the dressing. When it becomes necessary to change it, the old dressing can be removed easily without damage to the new tissue forming underneath. The gels are also useful as cell culture media. Pref. the gel consists of a mixt. of a hydrophilic polymer (I) and >=1 high molecular gel-forming substance. Esp. useful gels are comprised of a gel-forming polysaccharide and/or a protein or polypeptide, and a polymer of a hydrophilic (meth)acrylic acid deriv. made by polymerisation in the presence of the gel-forming substance. Suitable gel-forming substances are e.g., agarose and gelatin.
