Document Type and Number:
WIPO Patent Application WO/2021/174692
Kind Code:
A1
Abstract:
Disclosed in the present invention is a novel medical face mask having a replaceable filter system, comprising a cover and fixing bands. The cover is an inverted funnel-shaped structure having openings on both ends, an annular sealing pad is bonded to the edge at the bottom end of the cover, and a filter system is detachably connected to the opening at the top end of the cover. The filter system comprises a funnel-shaped installation base and a filter membrane fixedly connected to the installation base. By expanding the area of the filter membrane, ventilation resistance of the filter membrane is reduced, and the volume of air entering the filter membrane is increased. By setting the filter system to be detachable, the replacement of the filter system is easier, and the consumption of masks is reduced. The provision of an anti-spatter cap prevents a medical staff from suffering from the spatter of secretions that carry bacteria and viruses on the filter membrane of the mask during a use process, so that the risk of bacterial and viral infections of the medical staff is reduced.
