Abstract
A system for monitoring and controlling negative pressure wound therapy includes a microcontroller that controls means for maintaining reduced air pressure based on a pressure signal from a pressure sensor. The means for maintaining reduced air pressure may include a vacuum pump and valve. The system includes a mobile communication device having a microprocessor, touchscreen display, data storage device, GPS module, and wireless transceiver. The microprocessor generates control signals sent to the microcontroller to control the means for maintaining reduced air pressure to provide continuous or intermittent reduced air pressure. The microprocessor monitors the pressure signal and generates a closed-system alarm, leak-detected alarm or open-system alarm. The closed-system alarm indicates an air pressure leak rate below a closed-system threshold. The leak-detected alarm indicates an air pressure leak rate above a leak-detected threshold and below an open-system threshold. The open-system alarm indicates an air pressure leak rate above the open-system threshold.
