Method and device for inactivating viruses
The invention provides a device adapted for the inactivation of a virus in a fluid, the fluid being either a liquid or air containing breath moisture, comprising a housing delimiting a fluid passageway, the passageway being provided with a virus-inactivating material that has a copper (I) species and a copper (II) species as part of copper oxide compounds that release a combination of Cu + and Cu ++ copper ions into the fluid when exposed to the fluid that passes through the passageway for the inactivation of viruses passing therethrough.
1 . A device adapted for the inactivation of a virus in a fluid, said fluid being either a liquid or air containing breath moisture, comprising a housing delimiting a fluid passageway, said passageway being provided with a virus-inactivating material that has a copper (I) species and a copper (II) species as part of copper oxide compounds that release a combination of Cu + and Cu ++ copper ions into said fluid when exposed to said fluid that passes through said passageway for the inactivation of viruses passing therethrough.
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 compound having said copper (I) species and copper (II) species for inactivating HIV contained in fluid brought in contact therewith, followed by a layer of activated charcoal for removal of copper ions, followed by a filter for removal of residual charcoal particles.
3 . A device according to claim 2 further comprising pumping means.
4 . A device according to claim 2 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 filter 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 airborn virus and said copper oxide compounds having said copper (I) species and copper (II) species are attached to fibers incorporated into a non-wovern fabric.
8 . A method for the inactivation of a virus in a body fluid, comprising passing said body fluid through a device comprising a housing delimiting a fluid passageway, said passageway being provided with a virus-inactivating material having a copper (I) species and a copper (II) species as part of copper oxide compounds, whereby said filtering material is exposed to said body fluid and releases a combination of Cu + and Cu ++ copper ions into said body fluid passing through said passageway for the inactivation of viruses passing therethrough.
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.
