Abstract

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

Claims (36)

1. A wound treatment system comprising:

a wound dressing;

a fluid storage device configured to deliver a fluid to the wound dressing, wherein the fluid comprises molecules with a protective coating; and

an energy source configured to direct ultrasonic energy to the fluid and to degrade the protective coating and to activate a therapeutic property of the fluid.

2. The wound treatment system of claim 1 , wherein the energy source is configured to activate a component of the fluid that degrades the protective coating.

3. The wound treatment system of claim 1 , wherein the protective coating comprises a bioabsorbable glass.

4. The wound treatment system of claim 1 , wherein the protective coating comprises a ceramic.

5. The wound treatment system of claim 1 , wherein the energy source is configured to direct energy to the fluid proximal to the wound dressing.

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

7. The wound treatment system of claim 6 , wherein the energy source is configured to direct energy to the fluid in the conduit.

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

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

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

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

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

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

applying a wound dressing to the wound;

transporting fluid through a conduit to the wound dressing, wherein the fluid comprises molecules having a coating comprising an ultraviolet-activated protective material adapted to be partially broken down while traveling through the conduit; and

directing energy to the fluid proximal to the wound dressing to degrade the coating.

14. The method of claim 13 , wherein degrading the coating activates a therapeutic property of the fluid.

15. The method of claim 14 , wherein the therapeutic property includes an anti-biotic property.

16. The method of claim 14 , wherein the therapeutic property includes an analgesic property.

17. The method of claim 14 , wherein the therapeutic property aids with debridement of tissue.

18. The method of claim 14 , wherein the therapeutic property improves the ability to remove the wound dressing from a wound.

19. The method of claim 14 , wherein the therapeutic property reduces biofilm buildup in a wound.

20. A wound treatment system comprising:

a wound dressing;

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

a fluid comprising molecules with at least one type of therapeutic agent, wherein the molecules are constructed so that the therapeutic agent is inhibited by a light-sensitive branch which when broken thereby activates the therapeutic agent; and

an energy source configured to direct energy to the fluid and to control the light-sensitive branch of the molecules of the fluid.

21. The wound treatment system of claim 20 , wherein the fluid comprises an anti-microbial agent.

22. The wound treatment system of claim 21 , wherein the anti-microbial agent is hypochlorous acid (HOCl) or hypochlorite ion (ClO − ).

23. The wound treatment system of claim 20 , wherein the fluid comprises molecules having an active agent that is a clotting agent.

24. The wound treatment system of claim 23 , wherein the clotting agent is a trivalent salt, such as Fe +++ or Al +++ .

25. The wound treatment system of claim 24 , wherein the Fe +++ compound is encapsulated in a glucose sensitive microcapsule, which increases in permeability to allow for the release of the Fe +++ agent upon encountering glucose.

26. The wound treatment system of claim 20 , wherein the fluid comprises multiple agents which are activated by different wavelengths of light or frequencies of energy.
