Abstract

A rapid testing mechanism for respiratory viral pathogens includes a filter material positioned to capture exhaled breath particles from a respiratory tract. At least a portion of the filter material includes a pathogen binding adsorptive reagent, wherein the pathogen binding adsorptive reagent is a sulfated cellulose membrane. When the exhaled breath particles pass through the filter material, the following occur: when the 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 individuated by the filter material.

Claims (20)

1 . A standalone detection device for respiratory viral pathogens, including:

a filter material supported in a portable housing of the standalone detection device;

wherein the standalone detection device is configured and positioned for detection of proximate exhaled breath particles from a respiratory tract of a mammal without physically contacting the mammal;

wherein at least a portion of the filter material includes a pathogen binding adsorptive reagent, wherein the pathogen binding adsorptive reagent is heparin sepharose;

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

2 . The standalone detection device of claim 1 , wherein

the filter material includes multiple layers.

3 . The standalone detection device of claim 1 , wherein the filter material is packaged in a porous membrane.

4 . The standalone detection device of claim 3 , wherein the filter material includes multiple layers.

5 . A standalone detection device for respiratory viral pathogens, including:

a filter material supported in a portable housing of the standalone detection device;

wherein the standalone detection device is configured and positioned for detection of proximate exhaled breath particles from a respiratory tract of a mammal without physically contacting the mammal;

wherein at least a portion of the filter material includes a pathogen binding adsorptive reagent, wherein the pathogen binding adsorptive reagent is heparin sepharose;

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

wherein filter material includes porous adsorptive beads containing the pathogen binding adsorptive reagent.

6 . The standalone detection device of claim 5 , wherein the porous adsorptive beads containing the pathogen binding adsorptive reagent are positioned between two layers of multiple layers of the filter material.
