Abstract

A device for rapidly sanitizing a surface is described. The device has an enclosure having an opening adapted to insert a surface, and an interior; a liquid nitric oxide solution applicator; and an absorbent material. The liquid nitric oxide solution applicator is in fluid communication with the interior of the enclosure and is adapted to apply liquid nitric oxide solution onto the surface when the surface is positioned within the enclosure. A method of rapidly sanitizing a surface is described. The devices and methods provided herein may be implemented to sanitize the surface of any body part or item that may be placed within the device. An infectious agent on the surface may be killed; i.e., the surface is disinfected. Non-limiting applications of the devices and methods include preventing nosocomial infections or food contamination, sanitizing household items, and implementing sanitizing procedures to comply with FDA Good Manufacturing Practices.

Claims

1. A device for rapidly sanitizing a surface of an object comprising:

an enclosure having an opening adapted to insert the object therethrough, an interior portion of the enclosure adapted to receive the surface from the enclosure, and having an absorbent material; and

a liquid nitric oxide solution applicator comprising a liquid conduit, wherein the liquid conduit is connected to an atomizer or a nebulizer to dispense a liquid nitric oxide solution having an antimicrobial activity;

wherein the liquid nitric oxide solution applicator is in fluid communication with the interior portion of the enclosure and is adapted to apply the liquid nitric oxide solution onto the surface in a manner sufficient to rapidly sanitize the surface.

2. The device of claim 1 further comprising at least one of a container or scrubber configured to receive at least one of nitric oxide and reaction products with nitric oxide.

3. The device of claim 2 further comprising a containment system adapted to direct at least one of nitric oxide and reaction products with nitric oxide toward at least one of the absorbent material, into the container, and into the scrubber.

4. The device of claim 1 further comprising a system to deliver an oxygen-free inert gas atmosphere to the interior of the enclosure and/or maintain an oxygen-free inert gas atmosphere in the interior of the enclosure.

5. The device of claim 4, wherein the system includes a source of nitrogen, argon, carbon dioxide, another chemically unreactive gas, or combinations thereof, wherein the source is in fluid communication with the interior of the enclosure.

6. The device of any one of the preceding claims further comprising a tracking element.

7. A system comprising the device of claim 1 and at least one of a computer or network of computers, the computer or network of computers including a computer-readable medium and processor executable instructions stored in the computer-readable medium, wherein the processor executable instructions include instructions for rapidly sanitizing a surface comprising:

applying the liquid nitric oxide solution to a surface to be treated upon insertion the surface to be treated into the device.

8. The device of claim 1, wherein the enclosure encloses the surface such that at least one of nitric oxide and reaction products with nitric oxide are prevented from release into the atmosphere.

9. The device of claim 1, wherein the device is adapted to force at least one of nitric oxide and reaction products with nitric oxide through the absorbent material and draw air into the interior.

10. The device of claim 1, wherein the liquid nitric oxide solution is provided via the atomizer or nebulizer by a carrier gas.

11. The device of claim 10, wherein the carrier gas is air or nitrogen.

12. The device of claim 10, wherein the liquid nitric oxide solution is aerosolized.

13. The device of claim 10, wherein the atomizer or nebulizer is adapted to direct the liquid nitric oxide solution to the surface.
