Patents by Inventor Helen Burgess

Helen Burgess has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Absorbent multilayer hydrogel wound dressings
    Patent number: 8664464
    Abstract: The invention provides wound dressings comprising an absorbent (porous) hydrogel composition comprising a foam portion which comprises a flexible plasticized hydrophilic polymer matrix having an internal cellular structure, and a continuous portion which comprises a flexible plasticized hydrophilic polymer matrix having relatively continuous internal structure. The continuous portion of the hydrogel composition includes apertures providing fluid flow communication through the continuous portion between an external surface of the continuous portion and the foam portion whereby the foam portion can take up external water or other fluid into the cellular structure through the apertures of the continuous portion. The continuous portion of the hydrogel composition may be tacky to the skin, allowing its use as a bioadhesive.
    Type: Grant

  • Absorbent hydrogel compositions
    Publication number: 20060029652
    Abstract: The invention provides an absorbent (porous) hydrogel composition comprising a foam portion which comprises a flexible plasticised hydrophilic polymer matrix having an internal cellular structure, and a continuous portion which comprises a flexible plasticised hydrophilic polymer matrix having a relatively continuous internal structure. The continuous portion of the hydrogel composition includes apertures providing fluid flow communication through the continuous portion between an external surface of the continuous portion and the foam portion whereby the foam portion can take up external water or other fluid into the cellular structure through the apertures of the continuous portion. The continuous portion of the hydrogel composition may be tacky to the skin, allowing its use as a bioadhesive. The porous hydrogel has wide applicability, e.g. in wound or burn dressings, biomedical electrodes, etc., as an absorbent and/or adhesive component.
