Description

Inhalation and exhalation type mask {MASK THAT SEPARATES EXPIRATORY AND INSPIRATORY}

The disclosed subject matter relates to a mask worn to prevent viruses from entering the wearer through breathing.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and inclusion in this section is not an admission that it is prior art.

As is well known, the mask is made of breathable cotton or non-woven material, and is intended to prevent direct inflow of cold air into the respiratory tract during breathing in winter, and to prevent viruses contained in droplets when coughing or sneezing to people around them. The purpose of infecting or, on the contrary, blocking the inflow of viruses excreted from surrounding people into the body, the purpose of preventing secondary infection of medical staff from various infectious sources at medical sites, and blocking fine dust in industrial sites or air It is used for various purposes, etc.

Recently, the importance of wearing a mask is increasing as infectious diseases such as novel influenza (H1N1), Middle East respiratory syndrome (MERS), and coronavirus infection-19 (COVID-19) are prevalent worldwide. This conventional general mask consists of a main body that covers the wearer's nose and mouth, and an earring band for wearing the mask by hanging it on the ear.

However, in the case of general cotton masks or medical masks, the effect of blocking the influx of viruses is insignificant, so a mask with a 'KF80' index that can filter out more than 80% of fine particles with an average size of 0.6㎛ or an average of 0.4㎛ Disinfection masks with 'KF94' and 'KF99' indexes, which can filter out 94% and 99% of particles of this size, respectively, are popular.

However, these conventional quarantine masks do not differentiate between inhalation and exhalation, so it is difficult to breathe when worn for a long time, and dizziness occurs due to excessive carbon dioxide inhalation. In addition, when a virus carrier wears such a mask, there is a concern that the virus contained in the person's exhaled breath may be reintroduced into the inhaled breath, which may worsen the condition. In addition, conventional quarantine masks are not economical as they must be disposed of after being used once or twice, and it is difficult to purchase in bulk when a virus is prevalent. In addition, most quarantine masks do not have a separate filter, and even if they are provided, they perform only a function that helps the wearer breathe smoothly, so there is a limit that the inflow or discharge of viruses cannot be completely blocked.
