Negative pressure wound therapy apparatus, methods, and computer readable storage medium

Abstract

A negative pressure source can be fluidly connected to a wound dressing, the wound dressing can be positioned to cover at least a portion of a wound, and the negative pressure source can be controlled to supply negative pressure to the wound via a fluid flow path. An actuator of the negative pressure source can be controlled to operate in a dual mode by switching between proportional-integral (PI) control or proportional-integral-derivative (PID) control and pulse control. Stalling of the actuator can be prevented, and therapy can be provided without interruption.
