摘要：
A system comprises a negative-pressure source including a pump and an electric motor for maintaining negative-pressure at the wound and a pressure sensor for sensing a wound site pressure (WP). The system further comprises a system controller coupled to the first pressure sensor and the electric motor. The system controller maintains the wound site pressure (WP) within a hysteresis band by the application of power to the electric motor from a battery power source, based upon, at least in part a flow rate (FR) of fluid between the pump and the wound site as determined by the system controller. The hysteresis band including a maximum wound site pressure (WPMax) and a minimum wound site pressure (WPMin).
