Abstract
Some embodiments of a multi-layered dressing system for sealed wound treatment include various components used for sealing, dressing, suctioning and irrigating that are coupled together as a single, composite unit.
Claims20
A multilayered dressing system for negative pressure wound therapy, comprising:
- a hub including a manifold configured for connection with an inflow line that provides a first fluid pathway to an irrigation fluid source and an outflow line that provides a second fluid pathway to a vacuum source;
- a sealing layer comprising a film having a first surface and a second surface, the first surface being coupled to the hub, the second surface comprising a gel adhesive disposed at one or more peripheral locations on the film,
- a perforated layer coupled to the second surface of the sealing layer, the perforated layer defining a plurality of pores for fluid flow toward the hub;
- and
- an irrigation network coupled to the perforated layer, the irrigation network including a plurality of tubes in fluid communication with the first fluid pathway, each tube defining a lumen that adjusts from a collapsed condition to an expanded condition when subjected to positive pressure.

A multilayered dressing system, comprising:
- a hub having a manifold configured for connection with an inflow line that provides a fluid pathway to an irrigation fluid source;
- a sealing layer having a first surface and a second surface, the first surface being coupled to the hub;
- a netting layer coupled to the second surface of the sealing layer, the netting layer defining multiple openings for fluid flow toward the hub;
- and
- an irrigation network coupled to the netting layer, the irrigation network including a plurality of tubes in fluid communication with the fluid pathway, each tube defining a lumen that adjusts from a collapsed condition to an expanded condition when subjected to positive pressure.
