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.
Claims14
A sub-atmospheric wound-care system for treating an open wound comprising:
- a connector configured to be connected to wall suction as 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 pressure regulating sensor located proximate the wound for directly measuring the negative pressure at the wound;
- a collection canister configured to collect said liquid removed from the wound;
- and
- a porous dressing positioned over the wound.
A method of treating an open wound using a sub-atmospheric wound-care system, the method comprising:
- positioning a pressure sensor proximate the open wound;
- placing wound filler over the open wound, said pressure sensor being located between the wound filler and the open wound;
- placing a wound interface chamber over the wound filler;
- and
- connecting a regulated vacuum source to the wound interface chamber;
- wherein the regulated vacuum source is a wall suction source.
