Thehumidification system 1718 draws in ambient air, which is at a higher relative humidity than the oxygen-rich fluid discharged from theoxygen concentrator 1716, through aparticle filter 1722 and asecond valve 1723. The ambient air flows around an outside of the proton-exchange membrane tubes thereby creating a humidity gradient between the low-humidity the oxygen-rich fluid and the higher-humidity ambient air. Moisture is drawn from the ambient air across the proton-exchange membrane tube and into the oxygen-rich fluid thereby increasing a relative humidity of the oxygen-rich fluid.

In other embodiments, however, thesecond pressure sensor 1746 is disposed on an outer surface of thewound dressing 1706. During operation, the wound-care system 1700 may be operated to provide negative-pressure treatment simultaneously with oxygen-rich fluid treatment. In such a situation, thefirst pump 1708 and thesecond pump 1726 are activated simultaneously.

In such an arrangement thefirst pump 1708 and thesecond pump 1726 are operated sequentially. Thefirst pump 1708 and thesecond pump 1726 are typically peristaltic pumps. Thus, during operation, thefirst pump 1708 may cause slight pressure variations in thefluid tube 1748. In an effort to prevent pressure artifacts from thefirst pump 1706 from impacting the measured wound pressure, during periods where thefirst pump 1708 is operated alone, thereby providing oxygen-rich fluid therapy only to the wound, a pressure at the wound is monitored using thefirst pressure sensor 1742 due to the possibility of pressure artifacts at thesecond pressure sensor 1746. Alternatively, when thesecond pump 1726 is operated alone, thereby providing negative-pressure therapy only to the wound, a pressure at the wound is monitored using thesecond pressure sensor 1746 due to pressure variations being present in the negative-pressure tube 1744 from the peristaltic operation of thesecond pump 1726. -

FIG. 19C is a graph of pressure versus time illustrating sequential application of negative pressure and oxygen-rich fluid.FIG. 19C is a graphical illustration of a third treatment methodology in which variations in pressure are illustrated by theline 1932. During operation, the wound dressing 1706 is evacuated to the high-negative-pressure state for a first pre-determined period of time (t1). After the first predetermined period of time (t1), negative pressure is no longer applied to the wound dressing 1706 and oxygen-rich fluid is applied to the wound dressing for a second pre-determined period of time (t2). Application of the oxygen-rich fluid to the wound dressing 1706 raises a pressure under thewound dressing 1706. The oxygen rich fluid is held under the wound dressing 1706 for a third pre-determined period of time (t3). After the third pre-determined period of time (t3), negative pressure is applied to the wound dressing 1706 and the pressure is lowered to the high-negative-pressure state. The wound dressing is held at the high-negative-pressure state for the first pre-determined period of time (t1). This pattern repeats for the duration of the treatment. AlthoughFIG. 19C has been described herein as being used in conjunction with the wound-care system 1700, one skilled in the art will recognize that the wound-care device 1800 could also be utilized to deliver the therapeutic modalities illustrated inFIG. 19C . - Referring now to
FIG. 20 , there is shown a flow diagram of a process 2000 for treating a wound. The process 2000 begins atstep 2002. Atstep 2004, it is determined if the wound-care system 1700 will provide negative-pressure therapy, oxygen-rich fluid therapy, or simultaneous negative-pressure and oxygen-rich fluid therapy. Responsive to a determination that the wound-care system 1700 will provide negative-pressure therapy, the process 2000 proceeds to step 2006. Atstep 2006, it is determined if the wound-care system 1700 will provide constant or intermittent negative pressure. Responsive to a determination that constant negative-pressure will be provided, the process 2000 proceeds to step 2008. Atstep 2008, thesecond pump 1726 is utilized to optimize pressure evacuation from an area under thewound dressing 1706. Atstep 2010, a pressure under the wound dressing 1706 is monitored utilizing thesecond pressure sensor 1746. The negative pressure is maintained under the wound dressing 1706 for the duration of treatment. The process 2000 ends atstep 2022. - Still referring to
FIG. 20 , if it is determined atstep 2006 that intermittent negative pressure should be provided, the process 2000 proceeds to step 2012. Atstep 2012, thesecond pump 1726 is utilized to evacuate an area under the wound dressing 1706 to a high-negative-pressure state. In a typical embodiment, the high-negative-pressure state exposes an area under the wound dressing 1706 to a pressure of, for example, just below zero mmHg to approximately −300 mmHg. Atstep 2014, the area under the wound dressing 1706 is maintained at the high-negative-pressure state for a pre-determined period of time. Atstep 2016, after the pre-determined period of time has elapsed, the pressure under the wound dressing 1706 is raised to a low-negative-pressure state. In a typical embodiment, the low-negative-pressure state is at a pressure that is higher than the high-negative-pressure state. In a typical embodiment, the pressure under the wound dressing 1706 is raised by opening thethird valve 1732. Opening thethird valve 1732 allows ambient air to enter the wound-care system 1700 and thereby raises the pressure under thewound dressing 1706. Atstep 2018, the pressure under the wound dressing 1706 is maintained at the low-negative-pressure state for a second pre-determined period of time. After the second pre-determined period of time has elapsed, atstep 2020 it is determined if treatment is completed. Responsive to a determination instep 2020 that treatment is not completed, the process 2000 repeats to step 2012 and thesecond pump 1726 is utilized to evacuate the area under the wound dressing 1706 to the high-negative-pressure state. Responsive to a determination atstep 2020 that treatment is completed, the process 2000 ends atstep 2022. - Still referring to
FIG. 20 , responsive to a determination atstep 2004 only oxygen-rich fluid therapy should be provided, the process 2000 proceeds to step 2024. Atstep 2024, thefirst pump 1708 is utilized to supply the oxygen-rich fluid to thewound dressing 1706. Atstep 2026, the oxygen-rich fluid supplied by thefirst pump 1708 is humidified via thehumidification system 1718. Atstep 2028, a pressure under the wound-dressing 1706 is monitored via thefirst pressure sensor 1742. In a typical embodiment, introduction of the oxygen-rich fluid to the area under the wound dressing 1706 increases a pressure under a wound dressing 1706 to near atmospheric pressure. Atstep 2030, the oxygen-rich fluid is supplied to the wound dressing 1706 for a pre-determined period of time. After the pre-determined period of time has elapsed, the process 2000 ends atstep 2022. - Still referring to
FIG. 20 , if it is determined atstep 2004 that simultaneous application of oxygen-rich fluid therapy and negative pressure should be provided, the process 2000 proceeds to step 2032. At step 2032, thesecond pump 1726 is utilized to evacuate the area under the wound dressing 1706 to the high-negative-pressure state. Atstep 2034, the area under the wound dressing 1706 is maintained at the high-negative-pressure state for a pre-determined period of time. Atstep 2036, thefirst pump 1708 is utilized to deliver the oxygen-rich fluid to thewound dressing 1706. In a typical embodiment, delivery of the oxygen-rich fluid to the wound dressing 1706 raises a pressure under the wound dressing 1706 for a pre-determined time period. In various embodiments, the delivery of the oxygen-rich fluid under the wound dressing 1706 raises a pressure under the wound dressing to approximately the low-negative-pressure state. In other embodiments, the delivery of the oxygen-rich fluid raises the pressure under the wound dressing 1706 to a neutral-pressure state. That is, the pressure under the wound dressing is approximately equal to ambient atmospheric pressure. In still other embodiments, the delivery of the oxygen-rich fluid raises the pressure under the wound dressing to a pressure that is slightly above atmospheric pressure but less than venous backflow pressure. Referring to step 2036, when the predetermined time period has elapsed, the process 2000 proceeds to step 2038. Atstep 2038, thesecond pump 1726 is again utilized to evacuate the area under the wound dressing 1706 to the high-negative-pressure state. Atstep 2040, it is determined if the treatment is completed. Responsive to a determination the treatment is not completed, the process 2000 repeats to step 2032. Responsive to a determination that the treatment is completed, the process 2000 ends atstep 2022. - The previous Detailed Description is of embodiment(s) of the disclosure.
