Abstract: A negative pressure wound therapy system can include a reduced pressure wound therapy device and a wound therapy monitoring device configured to emit an indication when it detects that at least one parameter associated with the provision of negative pressure wound therapy is outside an operational range. The wound therapy monitoring device can operate in a low power mode in which the at least one parameter is periodically monitored. The reduced pressure wound therapy device can be configured to detect the indication and selectively generate an alarm. In some cases, the wound therapy monitoring device can be disposed in a wound or in a fluidic connector connecting the reduced pressure wound therapy device to the wound.

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

Abstract: Negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed.
