Kind Code:
A1
Abstract:
The present invention relates to a surgical mask used for preventing transmission of germs during a surgery and, more specifically, to a surgical mask having an external barrier film additionally formed at the outside of a filter film for filtering out germs or dust generated during a surgery, wherein the filter film and the external barrier film are integrally coupled to each other entirely or partially at the both side edges and are integrally coupled to each other at the lower parts, and the inner sides thereof are spaced apart from each other to form a space part therebetween so that the surgical mask allows the air rising from the lower part to flow outward by the external barrier film and allows the air in the upper space between the filter film and the external barrier film to be introduced and inhaled when a wearer breathes, and thus can minimize the inhalation of harmful gas.
