Abstract: Disclosed is an apparatus for the treatment of a wound on a patient. The apparatus is capable of administering localized negative pressure therapy to the wound using a negative pressure source and a drain line for removing exudate from the wound. The apparatus is also capable of administering localized hyperbaric fluid therapy to the wound using a fluid source and a supply line for supplying fluid to the wound.

Abstract: A high-velocity, accurately responsive impingement heater provides heated air at a substantially constant temperature to a process location to effect control of a process. The heater includes an air line for conducting air from an inlet thereof to the process location. A heat exchanger, including a plurality of electrical heating elements, heats air conducted through the air line. A power driver is connected to the heat exchanger and applies current to the heat exchanger. A controller is connected to the driver and receives a predetermined process temperature input from the user, as required for effecting control of the process. A process temperature sensor is positioned at the process location and measures the temperature of the air provided to the process location. The process temperature sensor provides a process temperature signal to the controller which is indicative of the air temperature at the process location.
