Abstract
Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.
Claims9
A dressing for treating a tissue site, the dressing comprising:
- a covering configured to be positioned over the tissue site to create a sealed space, the covering comprising:
- a film having a periphery and a center, an adhesive disposed on the periphery of the film, and the center of the film being free of the adhesive and configured to permit evaporation of water vapor through the center:
- a manifold configured to be positioned over the covering;
- and a drape configured to be positioned over the manifold and further configured to have a first aperture configured to be fluidly coupled to a forced-air device, and at least one second aperture configured to be fluidly coupled to an ambient environment to generate a fluid flow between the first aperture and the at least one second aperture in response to operation of the forced-air device.
