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: In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

Abstract: In one example embodiment, a system for stimulating healing of tissue at a wound site is disclosed. The system comprises a dressing including a porous pad and a drape covering the pad at a wound site for maintaining negative pressure at a wound site, a negative-pressure source including a pump and an electric motor to generate a pump pressure (PP) for applying to the wound site, and a first pressure sensor for sensing the pump pressure (PP). The system further comprises a controller coupled to the first pressure sensor and electric motor and including a PID controller that compares the pump pressure (PP) to a target pump pressure (TPP) and a bang-bang controller that controls wound pressure (WP) proximate the wound site, and wherein the controller is configured to alternatively select the bang-bang controller when the system is in a low-leakage condition or the PID controller when the system is in a high-leakage condition.
