Abstract: A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.

Abstract: A system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.
