Hydrogel wound dressing for use with suction |
| 摘要 |
A wound dressing comprising: an air-impermeable backing sheet having an aperture for attachment of a suction element; an air-permeable screen layer on a wound facing side of the backing sheet; and a substantially air-impermeable hydrogel layer extending across a wound facing side of said screen layer and joined in substantially airtight fashion to a periphery of said backing sheet around said screen layer. Also provided is a wound treatment system comprising a wound dressing according to the invention and a source of suction in fluid communication with said aperture. |

1. A wound dressing comprising:
an air-impermeable backing sheet having an aperture for attachment of a suction element; an air-permeable screen layer on a wound facing side of the backing sheet; and an continuous hydrogel layer covering a wound facing side of said screen layer and bonded to a periphery of said backing sheet around said screen layer to form an air-impermeable barrier adapted to maintain a pressure differential across the hydrogel layer under suction. |
