Anti-infection and toxin elimination device
| Details |
Inventors: Wen, Sheree H.;
Assignee:
Primary Examiner: Chiesa; Richard L.
Assistant Examiner:
Attorney, Agent or Firm: Katz, Esq.; Robert D. Cooper & Dunham LLP
The invention provides an apparatus for removing airborne pathogens and toxic substances from a surface of an article or a volume of air, comprising: a main processing chamber having a door for ingress to and egress from the main processing chamber, at least two high voltage electrodes for generating a current. The electrode can form ozone, if desired, to destroy pathogens. Optionally, the electrodes can be in a sealed or unsealed glass tube, with or without mercury, to generate ultraviolet light for photochemical reaction with pathogens or other contaminants. The apparatus also includes a post processing chamber comprising at least one filter for removing or absorbing airborne particulates and pathogens, and includes low voltage electrodes to neutralize charges in air transmitted from the main processing chamber. The system further includes a shutter between the main processing chamber and the post processing chamber for preventing ultraviolet light from entering the post processing chamber from the main processing chamber; and a fan for moving fluid from the main processing chamber to the post processing chamber. |

DETAILED DESCRIPTION The foregoing and other objects are achieved, and the disadvantages of prior devices overcome in accordance with the practice of the present invention.
The invention provides a germicidal device that can be used on food, liquid, solid surfaces and/or air, without using a radioactive process.
The device and the process do not harm or change the physical and chemical structure of the object.
The invention provides an apparatus for removing airborne pathogens and toxic substances from a surface of an article or a volume of air, comprising: a main processing chamber having a door for ingress to and egress from the main processing chamber, at least two high voltage electrodes for generating a current.
The electrode can form ozone, if desired, to destroy pathogens.
Optionally, the electrodes can be in a sealed or unsealed glass tube, with or without mercury, to generate ultraviolet light for photochemical reaction with pathogens or other contaminants.
The apparatus also includes a post processing chamber comprising at least one filter for removing or absorbing airborne particulates and pathogens, and includes low voltage electrodes to neutralize charges in air transmitted from the main processing chamber.
The system further includes a shutter between the main processing chamber and the post processing chamber for preventing ultraviolet light from entering the post processing chamber from the main processing chamber, and a fan for moving fluid from the main processing chamber to the post processing chamber.
The invention further provides a process for removing airborne pathogens and toxic substances from a surface of an article or a volume of air.
In one embodiment, the process comprises introducing the article or volume of air into a main processing zone having a pair of high voltage electrodes, and an optional ozone source and an optional ultraviolet light source.
The article or volume of air is exposed to the electric voltage from the high voltage electrodes, and optionally to ozone and ultraviolet light in the main processing zone for a period of time sufficient to kill pathogens, including bacteria, viruses, and spores, and to neutralize toxic substances or poisons on the article or in the volume of air
