摘要：
Systems, methods, and apparatuses for providing feedback for reduced-pressure treatment of a tissue site are described. A regulator may include a supply chamber fluidly coupled to the 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 therapy pressure. The feedback system may include one or more mechanical feedback interfaces fluidly coupled to the regulator to provide a signal of at least one of an application of reduced-pressure therapy, a leak condition, a blockage condition, and a canister full condition.
