Abstract
Methods and systems are provided for a sub-atmospheric wound-care (SAWS) system for treating an open wound. The SAWS system includes a regulated vacuum source for developing a negative pressure, a flow rate meter configured to measure a flow rate of liquid removed from the wound, a primary pressure regulating sensor located proximate the wound for directly measuring the negative pressure at the wound, a backup pressure regulating sensor located vacuum tube, a porous dressing suitable to be sealed airtight which is positioned within a wound interface chamber, a collection canister configured to collect said liquid removed from the wound, and an adapter configured to use wall suction a primary regulated vacuum source.
Claims18
A method for treating a wound with a negative pressure wound therapy system, comprising:
- applying a dressing system to a wound, the dressing system including:
- a silver-impregnated fine mesh layer having a lower face in contact with the wound, a layer of non-woven polymer material engaged with an upper face of the silver-impregnated fine mesh layer and having no free dangling edges, an interface chamber positioned over a central region of the layer of non-woven polymer material opposite from the silver-impregnated fine mesh layer, the interface chamber comprising an upper central coupling to receive a fluid tube and a lower region defining a plurality of rigid air chambers fixedly positioned relative to one another and in fluid communication with the upper central coupling, and a clear adhesive material being affixed to a skin region surround the wound so as to secure the interface chamber, the layer of non-woven polymer material, and the silver-impregnated fine mesh layer in an airtight region over the wound;
- connecting the fluid tube between the upper central coupling of the interface chamber and an electronic programmable vacuum regulator unit, the electronic programmable vacuum regulator unit having an intake connector configured to accept flow from a vacuum source;
- connecting the intake connector of the electronic programmable vacuum regulator unit to a fluid line coupled to the vacuum source so that the dressing system applies negative pressure wound therapy to the wound;
- and
- irrigating the wound with intermittent doses of an irrigation fluid that is delivered through the interface chamber and the non-woven polymer material of the dressing system.
