Abstract

A rapid testing mechanism for respiratory viral pathogens includes a filter material positioned to capture exhaled breath particles from a respiratory tract. A portion of the filter material is impregnated with a pathogen binding adsorptive reagent. When the exhaled breath particles pass through the filter material the following occurs: when the binding adsorptive reagent reacts, a positive test for respiratory viral pathogens is indicated by the filter material; and when pathogen binding adsorptive reagent does not react, a negative test for respiratory viral pathogens is indicated by the filter material.

Claims (26)

1. A rapid testing mechanism for respiratory viral pathogens, including:

a filter material positioned to capture exhaled breath particles from a respiratory tract;

wherein at least a portion of the filter material is impregnated with a pathogen binding adsorptive reagent;

a porous sealed packet containing the pathogen binding adsorptive reagent;

wherein, when exhaled breath particles pass through the filter material, the following occur:

when the pathogen binding adsorptive reagent reacts, a positive test for respiratory viral pathogens is indicated by the filter material; and

when the pathogen binding adsorptive reagent does not react, a negative test for respiratory viral pathogens is indicated by the filter material.

2. The testing mechanism of claim 1 , wherein the filter material is impregnated with greater than 0.2 mL of the pathogen binding adsorptive reagent.

3. The testing mechanism of claim 1 , wherein the filter material includes multiple layers.

4. The testing mechanism of claim 1 , wherein the porous sealed packet is positioned between two layers of multiple layers of the filter material.

5. The testing mechanism of claim 1 , wherein the respiratory viral pathogens include ribonucleic acid viruses.

6. The testing mechanism of claim 1 , wherein the filter material is a face mask covering a nose and mouth of a wearer.

7. The testing mechanism of claim 1 , wherein a housing structure for the filter may be packaged in porous polymeric membrane polyethylene.

8. A method of testing for respiratory viral pathogens, including steps of:

impregnating at least a portion of the filter material with a pathogen binding adsorptive reagent;

containing the pathogen binding adsorptive reagent within a porous sealed packet;

capturing exhaled breath particles from a respiratory tract with the filter material;

indicating, by the filter material, a positive test for respiratory viral pathogens when the pathogen binding adsorptive reagent reacts; and

indicating, by the filter material, a negative test for respiratory viral pathogens when the pathogen binding adsorptive reagent does not react.

9. The method of claim 8 , further including:

impregnating the filter material with greater than 0.2 mL of the pathogen binding adsorptive reagent.

10. The method of claim 8 , further including:

providing the filter material with multiple layers.

11. The method of claim 8 , wherein the respiratory viral pathogens include ribonucleic acid viruses.

12. The method of claim 8 , further including:

providing a face mask including the impregnated filter material covering a nose and mouth of a wearer.
