Abstract
Systems, methods, and apparatuses for providing feedback for reduced-pressure therapy are described. A regulator can include a supply chamber fluidly coupled to a dressing, a control chamber fluidly coupled to the dressing, a charging chamber fluidly coupled to the supply chamber through a port, and a regulator valve operable to control fluid communication through the port based on a pressure differential between the control chamber and a target pressure. The feedback system can include a printed circuit board, a pressure sensor and a signal interface communicatively coupled to the printed circuit board. The pressure sensor can be fluidly coupled to the control chamber to determine the pressure in the control chamber. The signal interface can indicate a state of the reduced-pressure therapy. A potential source can be communicatively coupled to the printed circuit board, the pressure sensor, and the indicator.
