1. A system for monitoring and controlling negative pressure wound therapy for treating a wound on a person'"'"'s body, the system comprising:

  • means for maintaining reduced air pressure in an airspace over the wound;

    a pressure sensor for sensing air pressure and generating a pressure signal based on sensed air pressure;

    a microcontroller in electrical communication with the means for maintaining reduced air pressure and the pressure sensor, the microcontroller for controlling the means for maintaining reduced air pressure based at least in part on the pressure signal from the pressure sensor;

    a mobile communication device comprising;

    a microprocessor in electrical communication with the microcontroller, the microprocessor for executing software instructions to generate control signals that are provided to the microcontroller to control the means for maintaining reduced air pressure to maintain one or more of a continuous reduced air pressure state or an intermittent reduced air pressure state in the airspace over the wound, the microprocessor for executing software instructions to monitor the pressure signal and generate one or more ofa closed-system alarm if the pressure signal indicates an air pressure leak rate that is below a closed-system threshold,a leak-detected alarm if the pressure signal indicates an air pressure leak rate that is above a leak-detected threshold and below an open-system threshold, andan open-system alarm if the pressure signal indicates an air pressure leak rate that is above the open-system threshold; and

    a wireless transceiver in electrical communication with the microprocessor, the wireless transceiver operable to transmit one or more of the pressure signal, the open-system alarm, the leak-detected alarm, and the closed-system alarm via one or more communication networks; and

    a negative pressure wound treatment service provider computer in communication with the wireless transceiver of the mobile communication device via the one or more communication networks and in communication with a healthcare provider computer via the one or more communication networks, the negative pressure wound treatment service provider computer operable to send an alert communication based on one or more of the pressure signal, the open-system alarm, the leak-detected alarm, and the closed-system alarm to the healthcare provider computer via the one or more communication networks.
