WIPO Patent Application WO/2023/040023
Kind Code:
A1
Abstract:
Disclosed is a mouth and nose mask having visually targeted collection of a novel coronavirus sample and a visual warning, belonging to the technical field of personal protection and pathogen sample collection. The mouth and nose mask comprises ear loops (3) as well as a mouth and nose mask body (1). An outermost layer of the mouth and nose mask (1) is an antifouling layer (7), an innermost layer is a skin-friendly layer (4), and a middle layer comprises a visible pathogen-targeted collection layer (5) or/and a filter layer (6). The visible pathogen-targeted collection layer (5) contains a color-changing material (8). The mouth and nose mask can visually target and collect saliva, droplet and aerosol-borne pathogens from suspected patients or patients with respiratory infectious diseases and also provides a warning function, thereby achieving the separation of the subject and the medical staff when collecting a novel coronavirus pathogen sample, reducing the risk of infection while increasing sample collection efficiency and reducing false negative rates.
