Wound care and infusion method and system utilizing a therapeutic agent
A wound-care system includes a first pump fluidly coupled to an oxygen source. An oxygen concentrator is fluidly coupled to the first pump. A humidification system is fluidly coupled to the oxygen concentrator. A wound dressing is fluidly coupled to the humidification system and to an exudate chamber. A negative-pressure tube fluidly is coupled to the exudate chamber. A first valve is disposed between the first pump and the oxygen concentrator. A second valve is disposed between the oxygen concentrator and the wound dressing. A third valve is disposed in the negative-pressure tube. 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.
