Claim 0:
1. A wound therapy system for delivering reduced pressure and irrigation fluid to a wound site, the system comprising:
a wound enclosure configured to form a substantially sealed volume around the wound site;
a wound exudate collection canister;
a primary pressure source configured to deliver the reduced pressure to the substantially sealed volume and deliver exudate collected from the wound site to the wound exudate collection canister through a first lumen;
a secondary pressure source configured to deliver a secondary pressure to the substantially sealed volume through a second lumen;
a fluid source configured to deliver irrigation fluid to the substantially sealed volume through the second lumen; and
a valve system fluidly coupled to the secondary pressure source and the fluid source, the valve system operable to selectively couple the secondary pressure source to the second lumen for delivering the secondary pressure to the substantially sealed volume independently of the irrigation fluid and selectively couple the fluid source to the second lumen for delivering the irrigation fluid to the substantially sealed volume independently of the secondary pressure,
wherein the wound therapy system includes:
a first mode of operation in which the primary pressure source delivers reduced pressure to the substantially sealed volume through the first lumen while the secondary pressure source delivers the secondary pressure to the substantially sealed volume through the second lumen and the valve system prevents delivery of the irrigation fluid to the substantially sealed volume through the second lumen; and
a second mode of operation in which the primary pressure source delivers reduced pressure to the substantially sealed volume through the first lumen while the fluid source delivers irrigation fluid to the substantially sealed volume through the second lumen and the valve system prevents delivery of the secondary pressure to the substantially sealed volume through the second lumen.
