Abstract
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.
