Abstract

Systems and methods of stimulating or activating fluids for use in wound treatment systems.

Claims (66)

1. A wound treatment system comprising:

a wound dressing;

a fluid storage device comprising a fluid, wherein the fluid storage device is in fluid communication with the wound dressing;

an energy source configured to direct energy to the fluid and to activate a therapeutic property of the fluid; and

wherein the energy source is configured to direct energy to the fluid proximal to the wound dressing.

2. The wound treatment system of claim 1 , further comprising a negative pressure source coupled to the wound dressing.

3. The wound treatment system of claim 1 wherein the fluid comprises molecules with a coating prior to exposure to the energy source.

4. The wound treatment system of claim 3 wherein the energy source is configured to degrade the protective coating.

5. The wound treatment system of claim 3 wherein the energy source is configured to activate a component of the fluid that degrades the protective coating.

6. The wound treatment system of claim 3 wherein the protective coating comprises a polymer shell.

7. The wound treatment system of claim 3 wherein the protective coating comprises a bioabsorbable glass.

8. The wound treatment system of claim 3 wherein the protective coating comprises a ceramic.

9. The wound treatment system of claim 1 wherein the energy source emits ultrasonic energy.

10. The wound treatment system of claim 1 wherein the energy source emits magnetic energy.

11. The wound treatment system of claim 1 wherein the energy source emits radio frequency energy.

12. The wound treatment system of claim 1 wherein the energy source emits ionizing radiation energy.

13. The wound treatment system of claim 1 wherein the energy source emits microwave energy.

14. The wound treatment system of claim 1 wherein the energy source emits light energy.

15. The wound treatment system of claim 1 further comprising a conduit in fluid communication with the fluid storage device and the wound dressing.

16. The wound treatment system of claim 15 wherein the energy source is configured to direct energy to the fluid in the conduit.

17. The wound treatment system of claim 15 further comprising a coupling member coupling the conduit to the wound dressing.

18. The wound treatment system of claim 17 wherein the energy source is configured to direct energy to the coupling member.

19. The wound treatment system of claim 1 wherein the therapeutic property includes an anti-biotic property.

20. The wound treatment system of claim 1 wherein the therapeutic property includes an analgesic property.

21. The wound treatment system of claim 1 wherein the therapeutic property aids with debridement of tissue.

22. The wound treatment system of claim 1 wherein the therapeutic property improves the ability to remove the wound dressing from a wound.

23. The wound treatment system of claim 1 wherein the therapeutic property reduces biofilm buildup in a wound.

24. A method of treating a wound, the method comprising:

applying a wound dressing to a wound;

transporting fluid to the wound dressing;

directing energy to the fluid and activating a therapeutic property of the fluid; and

wherein the energy is directed to the fluid proximal to the wound dressing.

25. The method of claim 24 further comprising applying a negative pressure to the wound dressing.

26. The method of claim 24 further comprising providing a fluid storage device and a conduit in fluid communication with the wound dressing.

27. The method of claim 26 wherein the energy is directed to the fluid when the fluid is in the conduit.

28. The method of claim 26 further comprising a coupling member coupling the conduit to the wound dressing.

29. The method of claim 28 wherein the energy is directed to the fluid at the coupling member.

30. The method of claim 24 wherein the fluid comprises molecules having a coating and an active agent, and wherein directing energy to the fluid breaks down the protective coating.

31. A wound treatment system comprising:

a wound dressing;

a fluid storage device comprising a fluid, wherein the fluid storage device is in fluid communication with the wound dressing;

an energy source configured to direct energy to the fluid and to activate a therapeutic property of the fluid;

a conduit in fluid communication with the fluid storage device and the wound dressing; and

wherein the energy source is configured to direct energy to the fluid in the conduit.

32. The wound treatment system of claim 31 , wherein the fluid comprises molecules with a coating prior to exposure to the energy source.

33. The wound treatment system of claim 32 , wherein the energy source is configured to degrade the protective coating.

34. The wound treatment system of claim 32 , wherein the energy source is configured to activate a component of the fluid that degrades the protective coating.

35. The wound treatment system of claim 32 , wherein the protective coating comprises a polymer shell.

36. The wound treatment system of claim 31 , wherein the energy source emits light energy.

37. The wound treatment system of claim 31 , further comprising a coupling member coupling the conduit to the wound dressing.

38. The wound treatment system of claim 37 , wherein the energy source is configured to direct energy to the coupling member.

39. A wound treatment system comprising:

a wound dressing;

a fluid storage device comprising a fluid, wherein the fluid storage device is in fluid communication with the wound dressing;

a conduit in fluid communication with the fluid storage device and the wound dressing;

a coupling member coupling the conduit to the wound dressing; and

an energy source configured to direct energy to the coupling member and to activate a therapeutic property of the fluid.

40. A method of treating a wound, the method comprising:

applying a wound dressing to a wound;

transporting fluid to the wound dressing;

providing a fluid storage device and a conduit in fluid communication with the wound dressing; and

directing energy to the fluid when the fluid is in the conduit and activating a therapeutic property of the fluid.

41. The method of claim 40 , further comprising applying a negative pressure to the wound dressing.

42. The method of claim 40 , further comprising coupling a coupling member to the conduit and the wound dressing.

43. The method of claim 42 , wherein the energy is directed to the fluid at the coupling member.

44. The method of claim 40 , wherein the fluid comprises molecules having a coating and an active agent, and wherein directing energy to the fluid breaks down the protective coating.
