Abstract

A system providing effective, broad spectrum UV-C or other ionizing radiation clinical surface disinfection, high intensity UV-C light emitting diodes (LEDs) of incrementally differing wavelengths are sequentially embedded in densely packed reflective nacels (cups or pockets) forming the surface of a rotating spherical or hemispherical structure. A combination of UV-C emitter component location and activation with the rotational and reciprocal elevation functions of such structures produces complete and continuous environmental overlapping UV-C energy scattering.

Claims

1. A system for disinfecting a clinical surface, the system comprising:

broad-spectrum UV-C or alternative ionizing radiation, the radiation produced by a plurality of high-intensity LED'"'"'s providing emissions at plurality of discrete and differing wavelengths, the LED'"'"'s oriented to direct the radiation towards the clinical surface;

a plurality of reflective nacelles, each of the reflective nacelles incorporating one or more of the high-intensity UV-C, or alternative ionizing radiation, LED'"'"'s, the plurality of reflective nacelles arranged as densely packed groups to form one or more pods, each pod comprising at least two LED'"'"'s of discrete and differing wavelengths; and

a rotating, at least partially spherical, support surface on which are positioned the plurality of reflective nacelles, the support surface operating to concurrently reciprocate linearly along its axis of rotation during use for enhanced energy diffusion.

2. The system of claim 1 wherein the plurality of pods are incrementally re-sequenced according to their LED'"'"'s of discrete and differing wavelengths to produce evenly overlapping output frequency diffusion.

3. The system of claim 1 wherein each of the plurality of reflective nacelles further comprise at least one high-intensity visible light emission LED, permitting initial operator system visible aiming and physical positioning for optimum disinfection performance by the avoidance of radiation shadows.

4. The system of claim 1 further comprising at least one automatic disinfection energy dosage monitor for measuring a quantity of radiation directed towards the subject surfaces or entities.

5. The system of claim 4 wherein the at least one automatic disinfection energy dosage comprise means for wirelessly communicating a signal to direct a system shut-down upon completion of a preset dose of disinfection energy.

6. The system of claim 1 further comprising a multi-directional external motion detection component allowing system shut-down if external motion is detected.

7. The system of claim 1 further comprising a system activation security component providing one or more operator identification protocols.

8. The system of claim 7 further comprising a plurality of individually digitally encoded wireless control components to allow remote control of the system and to prevent control cross-talk.

9. The system of claim 7 further comprising a time-delayed operator activation component, permitting effective treatment area exit time for a system operator.

10. The system of claim 1 wherein the at least partially spherical support surface comprises a hemispherical support surface positioned on a ceiling/wall-mount and the system further comprises a wireless operator control component.

11. The system of claim 1 wherein the at least partially spherical support surface comprises a hemispherical support surface positioned on a ceiling/wall-mount and the system further comprises alternately implemented AC line-power supply and battery power supply, the battery power supply incorporating battery condition indication.

12. The system of claim 1 wherein the at least partially spherical support surface comprises a spherical support surface and the overall system comprises a free-standing system and the system further comprises alternately implemented AC line-power supply and rechargeable battery power supply, the rechargeable battery power supply incorporating battery condition indication.

13. The system of claim 1 wherein the system comprises a mobile free-standing system and means for operator control to provide effective initial physical positioning of the system for optimum disinfection performance.

14. The system of claim 1 further comprising diffusion components, including rotating mirror components and Fresnel lens components.
