Rapid testing mechanism and method for respiratory viral pathogens
View Patent ↗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.
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.
