Abstract:
1. A therapeutic apparatus for treating ulcers, the apparatus comprising: an intermittent pneumatic compression unit comprising an oscillating air compressor fluidly connected to an air reservoir through a one-way check valve; a compression wrap fluidly connected to the air reservoir through a three-way valve; a vacuum assisted closure unit comprising a vacuum pump fluidly connected to a porous foam dressing through an intake vent; a single micro-controller unit comprising a three-way valve control circuit operably connected to the three-way valve, a compressor control circuit operably connected to the compression unit, a vacuum pump speed control circuit operably connected to the vacuum pump, a vacuum pump control circuit operably connected to the vacuum pump, a pressure sensor operably connected between the air reservoir and the compression wrap, and a vacuum sensor operably connected between the vacuum pump and the porous foam dressing; whereby the micro-controller unit is operable to cause the compression unit to supply compressive force to the compression wrap and to cause the vacuum assisted closure unit to supply a vacuum to the porous foam dressing.
