System and method for purging a reduced pressure apparatus during the administration of reduced pressure treatment
First Claim
1. A method of administering a reduced pressure tissue treatment to a tissue site comprising:
- positioning a primary manifold having apertures in fluid communication with a secondary manifold;
positioning the secondary manifold having a plurality of flow channels adjacent the tissue site such that at least a portion of the flow channels are in fluid communication with the tissue site, wherein the secondary manifold prevents direct contact between the primary manifold and the tissue site;
applying a reduced pressure to the tissue site through the secondary manifold from a first conduit having at least one outlet in fluid communication with the flow channels; and
purging blockages in or near the first conduit by delivering a fluid through a second conduit in an area in proximity to the at least one outlet of the first conduit.

Abstract
A reduced pressure delivery system for applying a reduced pressure to a tissue site is provided. The system includes a manifold having a plurality of flow channels. The manifold is configured to be placed adjacent the tissue site. A first conduit is in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels. A second conduit is in fluid communication with the flow channels of the manifold and is operably connected to a valve. The valve selectively purges the second conduit with ambient air when the valve is positioned in an open position, and a controller is operably connected to the valve to place the valve in the open position for a selected amount of time at a selected interval during delivery of reduced pressure through the first conduit.

16. A method of administering a reduced pressure tissue treatment to a tissue site comprising:
-
positioning a primary manifold having apertures in fluid communication with a secondary manifold; positioning the secondary manifold having a plurality of flow channels adjacent the tissue site such that at least a portion of the flow channels are in fluid communication with the tissue site, wherein the secondary manifold prevents direct contact between the primary manifold and the tissue site; applying a reduced pressure to the tissue site through the secondary manifold from a first conduit having at least one outlet in fluid communication with the flow channels; and opening a valve operably associated with a second conduit to expose the conduit to a fluid at a pressure greater than the reduced pressure, the valve being opened for a selected amount of time at a selected interval to allow the fluid to be delivered through the second conduit to assist in clearing blockages within or near the first conduit. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
