Method and device for inactivating viruses
The invention provides a device for the inactivation of a virus comprising a housing delimiting a fluid passageway, the passageway being provided with a filtering material having ionic copper selected from the group consisting of Cu + and Cu ++ ions and combinations thereof incorporated therein.
1. A device for the inactivation of a virus comprising: a housing delimiting a fluid passageway, said passageway being provided with a virus-inactivating fibrous material, said virus-inactivating fibrous material comprising a plurality of fibers having incorporated therein a single antiviral component consisting essentially of a water-insoluble form of opper oxide molecules which release both Cu + and Cu ++ ions, wherein the copper oxide molecules are directly attached to the fibers in said material by an electro-less plating process involving reduction of cationic copper from a copper solution, and wherein the ionic copper is exposed to fluid in the passageway to allow for atomic dispersion of the ionic copper into the fluid, whereby the ionic copper can inactivate a virus present in the fluid.
2. A device according to claim 1 comprising a multi-layered filter having a first porous medium at the inlet thereof, followed by a material containing said copper oxide molecules, followed by a layer of activated charcoal for removal of copper ions, followed by a filtering material for removal of residual charcoal particles.
3. A device according to claim 2 further comprising a pump that facilitates transfer of a media through the device.
4. A device according to claim 2 further comprising a filter of up to 0.6 microns for removal of white blood cells from the fluid passing therethrough.
5. A device according to claim 2 wherein said filtering material for removal of said charcoal particles prevents the passage of particles greater than 0.4 microns.
6. A device according to claim 1 wherein said device is a gas mask.
7. A device according to claim 6 wherein said virus is an airborne virus and said copper oxide molecules which release both Cu + and Cu ++ ions are directly attached to fibers incorporated into a non-woven fabric.
8. A method for inactivating a virus found in a body fluid, comprising:
passing said body fluids through a device as defined in claim 1 wherein live virus in the body fluid is inactivated after passing through the device.
9. A method according to claim 8 wherein said virus is HIV.
10. A method according to claim 8 wherein said body fluid is blood.
11. A method according to claim 8 wherein said body fluid is milk.
12. A method according to claim 8 wherein said body fluid is blood which is then returned to the body from which it has been drawn.
13. A method according to claim 8 wherein said virus is West Nile Fever Virus.
14. A device for inactivating airborne epidemial viruses, said device being provided with a virus-inactivating fibrous material, said virus-inactivating fibrous material comprising a plurality of fibers having incorporated therein a single antiviral component consisting essentially of a water-insoluble form of copper oxide molecules which release both Cu + and Cu ++ ions, wherein the copper oxide molecules are directly attached to fibers by an electro-less plating process involving reduction of cationic copper from a copper solution, wherein said fibers are incorporated in a layer in said device and wherein said device is a gas mask.
15. A device according to claim 14 wherein said virus is an airborne virus and said copper oxide molecules which release both Cu + and Cu ++ ions are directly attached to fibers incorporated into a non-woven fabric.
