Wound care and infusion method and system utilizing a therapeutic agent

A wound-care system comprising:

• a first pump fluidly coupled to an oxygen source;
• an oxygen concentrator fluidly coupled to the first pump;
• a humidification system fluidly coupled to the oxygen concentrator;
• a wound dressing fluidly coupled to the humidification system and to an exudate chamber;
• a negative-pressure tube fluidly coupled to the exudate chamber;
• a first pressure sensor exposed to pressure in the negative-pressure tube;
• a second pressure sensor exposed to pressure between the oxygen concentrator and the wound dressing;
• a first valve disposed between the first pump and the oxygen concentrator, the first valve being operable to selectively direct flow of fluid from the first pump to at least one of the oxygen concentrator and the humidification system;
• a second valve disposed between the oxygen concentrator and the wound dressing, the second valve being operable to selectively vent the wound dressing to an exterior environment;
• a third valve disposed in the negative-pressure tube, the third valve being operable to selectively vent the wound dressing to the exterior environment;
• and
• wherein selective activation of the first pump, the first valve, the second valve, and the third valve facilitates delivery of at least one of individual, sequential, or simultaneous negative-pressure treatment and oxygen-rich fluid treatment to the wound via the wound dressing.
