Making process of active gauze mask capable of filtering out pathogenic microorganism

Abstract

The making process of active gauze mask capable of filtering out pathogenic micro organism includes the first extraction of tannic acid solution from plant; the subsequent soaking gauze in the tannicacid solution and drying to form pathogenic micro organism filtering layer;the third spraying of ethanol solution of antiseptic plant essential oil to the gauze and drying; and the final making the gauze mask with double gauze layer with plant essential oil and the filtering layer with tannic acid. The present invention has no toxic and harmful matter, and can capture and kill pathogenic micro organism with effective rate as high as 98 %.

Description

technical field [0001] The invention relates to a preparation method of an active mask capable of filtering pathogenic microorganisms. The mask is suitable for people in areas with infectious diseases, especially for people engaged in infectious viruses. Background technique [0002] In order to prevent external harmful substances from entering the respiratory system, increasing the density and thickness of the filter layer of the mask can improve the effect of dust-proof filtration. Some use electrostatic filter cotton (such as 3M protective masks), and some use activated carbon (large breathing resistance, It can only absorb lipophilic substances) and other adsorption media to increase its adsorption capacity, and can also adsorb some harmful gases. The function of general medical mask can be divided into two kinds, one is to avoid passive infection (such as the N95 mask of American Megatech Scientific Co., Ltd. and the FFP1 and FFP2 masks passed by ...

AI Technical Summary

Problems solved by technology

The function of general drug mask can be divided into two kinds, one is to avoid passive infection (such as the N95 mask of American Megatech Scientific Co., Ltd. and the FFP1 and FFP2 masks passed by the European Community. However, the disadvantages of this type of mask are: cannot avoid active infection); another can prevent the virus from being transmitted to others by the sick person (such as medical surgical masks)

However, none of these methods can effectively filter pathogenic microorganisms such as viruses. This is because the size of the virus is only 20-30nm, and the pore size of a micron mask is thousands of times larger than that of the virus. Large; even if bacteria or viruses can be blocked by the mask, since the general mask itself has no bactericidal function, these bacteria or viruses can still survive on the mask for several hours or even tens of hours
