System and method for purging a reduced pressure apparatus during the administration of reduced pressure treatment
First Claim
1. A reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site comprising:
- a manifold having a plurality of flow channels, the manifold configured to be placed adjacent the tissue site;
a first conduit in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels;
a second conduit in fluid communication with the flow channels of the manifold;
a valve operably connected to the second conduit to selectively purge the second conduit with ambient air when the valve is positioned in an open position;
a controller 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.

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.

11. A method of administering a reduced pressure tissue treatment to a tissue site comprising:
-
positioning a 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; applying a reduced pressure to the tissue site through 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 to an area in proximity to the at least one outlet of the first conduit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of administering a reduced pressure tissue treatment to a tissue site comprising:
-
positioning a 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; applying a reduced pressure to the tissue site through 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 (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
