Reduced-pressure systems, methods, and devices for simultaneously treating a plurality of tissue sites

A system for simultaneously treating a plurality of tissue sites on a patient, the system comprising:

• a plurality of reduced-pressure dressings;
• a plurality of multi-lumen reduced-pressure delivery conduits, wherein each multi-lumen reduced-pressure delivery conduit includes at least a pressure-sampling lumen and at least a reduced-pressure supply lumen;
• a fluid storage device fluidly coupled to the plurality of reduced-pressure dressings for receiving and at least temporarily storing fluids;
• and
• a multi-port therapy unit comprising:
• a controller,
• a plurality of patient-side ports, wherein each of the plurality of patient-side ports is configured to fluidly couple with one of the plurality of multi-lumen reduced-pressure delivery conduits and with at least one of the pressure-sampling lumens and one of the reduced-pressure supply lumens therein,
• a plurality of reduced-pressure plenums, each of the plurality of reduced-pressure plenums associated with one of the plurality of patient-side ports,
• a plurality of treatment pressure sensors, wherein each of the plurality of treatment pressure sensors is associated with one of the plurality of patient-side ports for determining a pressure associated with the at least one pressure-sampling lumen in the multi-lumen reduced-pressure delivery conduit associated with the patient-side port, wherein each treatment pressure sensor is operatively coupled to the controller to provide a treatment pressure signal to the controller,
• a plurality of plenum pressure sensors, each of the plurality of plenum pressure sensors is associated with one of the plurality of reduced-pressure plenums and is operatively coupled to the controller for supplying a plenum pressure signal,
• a first plurality of control valves fluidly coupled between each of the plurality of reduced-pressure plenums and an associated patient-side port, wherein each of the first plurality of control valves is operatively coupled to the controller so that each of the first plurality of control valves may be controlled by the controller,
• a main vacuum source fluidly coupled to each of the plurality of plenums for supplying reduced pressure to each of the plurality of reduced-pressure plenums;
• a second plurality of control valves fluidly coupled between each of the plurality of reduced-pressure plenums and the main vacuum source, and
• wherein the controller is operative to regulate the reduced pressure supplied from the plurality of reduced-pressure plenums to the plurality of patient-side ports by controlling the first plurality of control valves and to regulate the reduced pressure supplied to the plurality of reduced-pressure plenums using the second plurality of control valves.
