Abstract
Provided, in one embodiment, is a vacuum wound dressing for covering a wound bed comprising: a wound contact layer comprising a fibrous blend or fibrous material that forms a cohesive gel when wetted by wound exudate; a source of vacuum situated to be separated from the wound bed by the wound contact layer; and a vacuum sealing layer covering the wound contact layer and adapted to retain relative vacuum in the wound contact layer, wherein (i) the dressing is essentially missing a non-gelling, foam layer in which the source of vacuum is situated or (ii) the vacuum sealing layer comprises as an outer layer a foam layer.
Claims7
A vacuum wound care module comprising:
- a fluid reservoir;
- a pump module fluidly connected to the fluid reservoir and adapted for pumping fluid out of the fluid reservoir;
- a venturi vacuum fitting fluidly connected to the pump module and having a vacuum outlet and a fluid outlet;
- a fluid connection from the fluid outlet to the fluid reservoir;
- a trap reservoir fluidly connected to the vacuum outlet;
- and
- a second fluid connection that is one of:
- (a) fluidly connected to the trap reservoir and (i) adapted to be fitted with a wound dressing to provide vacuum and allow removal of wound exudate or (ii) fitted to such a wound dressing such that, when the wound dressing is employed, it provides vacuum and allows removal of wound exudate, or
- (b) adapted to be fluidly connected to the trap reservoir and fitted to such a wound dressing such that, when the wound dressing is employed, it provides vacuum and allows removal of wound exudate.
