This invention provides a respirator for detecting viruses which cause respiratory tract infection. The respirator comprises an outer layer, an inner layer, a rapid screening reagent between the outer layer and the inner layer, and a water-resist membrane between the rapid screening reagent and the inner layer. A sample pad of the rapid screening reagent is located on a region close to the nostrils, such that air from the nostrils will arrive the sample pad. Viruses inside the air with vapors or moistures will flow inside the rapid screening reagent through a conjugate pad, a nitrocellulose membrane, and an absorption pad. At least one test line will indicate a corresponding virus.

The present invention relates to a mask for detecting the COVID-19 virus, and more specifically, to a mask for detecting the COVID-19 virus which comprises: a mask main body; earrings for fixing the mask main body to the ears; and a COVID-19 virus detection unit formed on a portion of the mask main body, wherein the COVID-19 virus detection unit is formed by applying a biomarker molecule capable of binding to the COVID-19 virus to the mask main body and a color signal is produced to make it possible to detect the virus when the biomarker molecule binds to the COVID-19 virus in the air or breathing. According to the present invention, it is possible to check in real-time whether a mask wearer or a counterpart is infected with the COVID-19 virus through the color change of the virus detection unit visible on the exterior of a mask while wearing the mask during daily life.

The novel and improved face mask materials with inherent virucidal activity not onlyreduces/nullifies the viral load via inhalation, but reduces the transmission from both the inhalation and contact routes by contributing to good hygienic practice thus reducing the impact of asymptomatic carriers and patients with low-grade disease in the community. This prevents the possibility for re-inhalation of carbon dioxide-rich air and gives comfort to the wearer. Variable enhancement of the virucidal, filtration and hydrophobic activities across multiple layers are achieved to suit different cohorts within the general populace as well asthe Healthcare system afflicted by the COVID-19 pandemic. Uniquely different types of face masks are custom-made with suitable degrees of enhancement of outer, middle and inner layers for different requirements of specified end-user populations utilizing commonly available, low-cost material. In addition to the above advantages, the present invention is fabricated of biodegradable materials at the same time it can be washed several times afterusage making it cost effective. It is also constructed in way that it can fit the face of the wearer perfectly without any spaces in-between. Further applications for this unique invention, combining nano-filtration with virucidal properties via use of nanotechnologyincludes, advanced filtration of artificial ventilator machines, air-purifiers, air-conditionerfiltration systems and Health care system usage as in bedding, scrub suits, clothing, etc. Theuse of germicidal properties would complement measures usually practiced for seasonalinfluenza and should also be considered for other diseases transmitted via inhalation route.

Appl.No 17387509 Applicant Suresh Bhate Inventor Suresh Bhate

The present disclosure relates generally to air filtration devices. More specifically, but not exclusively, the present disclosure relates to an air filtration device comprised of a copper (or copper alloy) medium to inactivate airborne pathogens (e.g., viruses, bacteria, coronaviruses, COVID-19, etc.) and mitigate harmful exposure to said pathogens. The copper medium is a porous mesh (i.e., copper wool) that is positioned within or on a structure to provide support. The air filtration device may be positioned in an HVAC system such that an air stream flows through the copper medium to inactivate airborne pathogens, such as viruses, in the air stream. The air filtration device may be used in combination with, or in addition to, existing HVAC system conventional air filters (e.g., HEPA filters). The air filtration device includes a copper medium positioned on a face mask to inactivate airborne pathogens during respiratory processes.
