Novel aerosol and droplet coronavirus pathogen collection mask and collection method

Abstract

The invention discloses a novel aerosol and droplet coronavirus pathogen collection mask and a collection method. The mask comprises ear hooks, a mask body and a breather valve on the mask body, the breather valve comprises an antifouling layer, a filtering layer, a heat preservation layer, an antibacterial virus layer and a skin-friendly layer, and the breather valve further comprises a pathogencollecting layer which sequentially comprises the antifouling layer, the filtering layer, the antibacterial virus layer, the heat preservation layer, the pathogen collecting layer and the skin-friendly layer from outside to inside. The invention realizes a new sampling mode which is convenient and simple to use and can realize aerosol and droplet pathogens and even sputum, and is beneficial to saving medical resources and improving the positive rate of samples. A breather valve of an existing KN95 mask is modified into a detachable valve with filtering and enriching functions, and large-scaleproduction of the breather valve can be achieved. Production difficulty is low, and the minvention is simple and easy to implement.

Description

Technical field: [0001] The invention belongs to the field of pathogen collection, and in particular relates to an aerosol and droplet novel coronavirus pathogen collection mask and collection method. Background technique: [0002] The clinical features of new coronavirus infection are fever, dry cough, shortness of breath, low or low white blood cells in peripheral blood, and inflammatory changes on chest radiograph. The World Health Organization (WHO) confirmed and named its pathogen SARS-COV-2, a new type of coronavirus belonging to the beta genus, and designated it as an international public health emergency (Public Health Emergency of International Concern, PHEIC) on January 31, 2020 ). Viral pneumonia is a highly hazardous disease that seriously damages public health, especially the unknown new type of coronavirus pneumonia. [0003] At present, the most commonly used specimens for diagnosis of lung infection are sputum and pharyngeal test sub-samples. However, a key issue...
