Abstract

A patient support includes a patient support surface, a barrier adjacent the patient support surface, with a portion of the barrier or patient support surface including at least one material suspended therein, applied thereto, or embedded therein having an antimicrobial property, and an energy generation system directing energy to the portion or another portion of the barrier or patient support surface, the energy comprising a current, a field, heat, sound waves, or light to provide antimicrobial treatment to the portion or the other portion.

Claims

1. A patient support comprising:

a patient support surface;

a barrier adjacent said patient support surface;

said barrier or said patient support surface including a body forming an exterior surface of said patient support;

a material having antimicrobial properties embedded in, applied to, or suspended in said body to provide antimicrobial treatment at said exterior surface; and

an energy generation system directing energy to said body to provide an antimicrobial treatment to said body at said exterior surface, said energy generation system operable to generate UV light, wherein the UV light is directed into said body, and said body being formed from a material enabling total internal reflection of the UV light so that the light when directed into said body is substantially retained within said body to thereby protect a patient supported on the patient support from the UV light.

2. A component of medical equipment, said component comprising:

a body, said body being adapted to mount to a patient support and to form an exterior surface of the patient support when mounted to the patient support;

a material having antimicrobial properties embedded in, applied to, or suspended in said body to provide antimicrobial treatment at said exterior surface; and

an energy generation system applying energy to said body to provide an antimicrobial treatment to said body at said exterior surface to thereby protect a patient supported nearby from the energy.

3. The component according to claim 2, in combination with a patient support, said patient support comprising:

a patient support surface;

a barrier adjacent said patient support surface;

said barrier or said patient support surface including said body; and

said energy generation system applying a current, a field, heat, sound waves, or light to provide antimicrobial treatment to said body.

4. The component according to claim 3, wherein said material comprises copper or a copper alloy.

5. The component according to claim 3, wherein said material comprises copper powder or copper alloy powder.

6. The component according to claim 3, wherein said material comprises a copper or copper alloy coating.

7. The component according to claim 3, wherein said material comprises copper bodies suspended in said body.

8. The component according to claim 3, wherein said material comprises a copper plate.

9. The component according to claim 3, wherein said energy generation system generates UV light.

10. A method of cleaning medical equipment comprising:

providing a patient support according to claim 3; and

directing energy into or through the body of the patient support with the energy generation system to thereby provide antimicrobial treatment at said exterior surface.

11. The method according to claim 10, wherein said directing energy includes directing light into the body.

12. The method according to claim 11, wherein said directing light comprises directing UV light into the body at an angle such that there is total internal reflection in the body thereby protecting a patient supported on the patient support from the UV light.

13. The component according to claim 2, wherein said energy generation system generates infrared light.

14. The component according to claim 2, wherein said energy generation system generates current in the range of 1 milliamp to 10 milliamps.

15. The component according to claim 2, wherein said energy generation system generates an electric charge.

16. The component according to claim 2, wherein said energy generation system generates a magnetic field.

17. The component according to claim 2, wherein said energy generation system generates heat.

18. The component of medical equipment according to claim 2, wherein said material comprises at least copper or a copper alloy.

19. The component of medical equipment according to claim 2, wherein said energy generation system generates UV light.

20. The component of medical equipment according to claim 19, wherein the body is formed from a material enabling total internal reflection of the UV light so that the UV light when directed into the body is substantially retained within said body to thereby protect a patient supported on the patient support from the UV light.

21. The component according to claim 2, wherein said body is adapted to form a part of the patient support.

22. The component according to claim 21, wherein said component comprises a side rail, a caster wheel assembly, a headboard, a foot board, or a work surface.

23. The component according to claim 21, wherein said material having antimicrobial properties is suspended in said body.

24. The component according to claim 22, wherein said component comprises a caster wheel assembly, said body forming a wheel of said caster wheel assembly, and said energy generation system generating UV light and directing the UV light to the wheel.
