Abstract: In one example embodiment, an apparatus for providing negative-pressure therapy may comprise a negative-pressure source, a pressure sensor, and a control valve. The negative-pressure source may be configured to be fluidly coupled to a distribution component. The control valve may be fluidly coupled to the pressure sensor and configured to be selectively coupled to the negative-pressure source, the distribution component, or both. A controller may also be configured to operate the control valve to selectively couple the pressure sensor to at least one of the negative-pressure source and the distribution component through the control valve, and the pressure sensor may provide a feedback signal to the controller indicative of pressure in a feedback path associated with the position of the control valve. The controller may also be configured to operate the negative-pressure source based on the feedback signal.

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 cover for protecting a tissue site may comprise a shell layer, an adhesive disposed on the shell layer, and a contact layer disposed adjacent to the adhesive. The contact layer may have an open area of about 40 percent to about 50 percent of the total area of the contact layer. A release liner may be disposed adjacent to the contact layer. Perforations through the shell layer and the contact layer can define a sacrificial segment configured to be separated from the shell layer and the contact layer. A handling bar may be coupled to the sacrificial segment.
