Abstract

Disinfection using light therapy is described herein where a support platform which is configured to support a region of a patient's body may integrate or incorporate one or more light elements positioned within, upon, or in proximity to the support platform for exposing the patient's body to the light therapy. Additionally, light sources and/or heating elements may also be incorporated with mattresses and/or covers for disinfection prior to patient use.

Claims (28)

1. A method for disinfecting a surface, comprising:

illuminating a light upon a first region of a mattress or cover, wherein the light is tuned to emit one or more wavelengths suitable for disinfecting one or more bacterial strains present upon the mattress or cover;

moving the light to at least a second region of the mattress or cover after a predetermined period of time while under control of a controller; and

heating a thermochromatic layer in proximity to the mattress or cover.

2. The method of claim 1 wherein the illuminating comprises emitting the one or more wavelengths ranging from 200 nm to 3000 nm.

3. The method of claim 1 further comprising applying heat to the mattress or cover under control of the controller.

4. The method of claim 1 wherein the illuminating further comprises heating the mattress or cover to a temperature of up to 60° C.

5. The method of claim 1 wherein the illuminating comprises transmitting the light via one or more optical fibers.

6. The method of claim 1 wherein the moving the light comprises moving the light via a roller mechanism positioned upon the mattress or cover.

7. The method of claim 1 wherein the moving the light comprises moving the light via a rail positioned in proximity to the mattress or cover.

8. The method of claim 1 wherein the moving the light comprises moving the light along an arbitrary path over the mattress or cover.

9. The method of claim 1 further comprising positioning a fluid layer upon the mattress or cover.

10. The method of claim 9 further comprising transmitting a second light through the fluid layer.

11. The method of claim 9 further comprising anchoring the fluid layer upon the mattress or cover.

12. A method for disinfecting a surface, comprising:

illuminating a light upon a first region of a mattress or cover, wherein the light is tuned to emit one or more wavelengths suitable for disinfecting one or more bacterial strains present upon the mattress or cover;

moving the light to at least a second region of the mattress or cover after a predetermined period of time while under control of a controller;

positioning a fluid layer upon the mattress or cover;

anchoring the fluid layer upon the mattress or cover; and

heating a thermochromatic layer in proximity to the mattress or cover.

13. The method of claim 12 wherein the illuminating comprises emitting the one or more wavelengths ranging from 200 nm to 3000 nm.

14. The method of claim 12 further comprising applying heat to the mattress or cover under control of the controller.

15. The method of claim 12 wherein the illuminating further comprises heating the mattress or cover to a temperature of up to 60° C.

16. The method of claim 12 wherein the illuminating comprises transmitting the light via one or more optical fibers.

17. The method of claim 12 wherein the moving the light comprises moving the light via a roller mechanism positioned upon the mattress or cover.

18. The method of claim 12 wherein the moving the light comprises moving the light via a rail positioned in proximity to the mattress or cover.

19. The method of claim 12 wherein the moving the light comprises moving the light along an arbitrary path over the mattress or cover.

20. The method of claim 12 further comprising transmitting a second light through the fluid layer.
