Gauze mask

Abstract

The gauze mask includes one obstructing part and one connected isolating part. The obstructing part has one obstructing layer made of airtight and water impermeable material to cover face. The isolating part around the mouth and nose is shielded and supported with the obstructing part to form one air permeating space around the mouth and nose. Inspired fresh air and expired CO2 pass through the isolating part, and the suspended particle in air, including droplet, is obstructed completely. The present invention can prevent droplet infection.

Description

technical field [0001] The invention relates to a mask, in particular to a mask which can reliably prevent droplets from spreading diseases. Background technique [0002] The gradual expansion of SARS epidemic has caused serious panic at home and abroad. Current evidence shows that SARS is mainly transmitted through the droplets of patients. The virus exists in droplets (saliva droplets). Since water droplets are heavier than air, the virus will not float in the air. Therefore, the current prevention of SARS transmission The main way is to wear a mask to avoid the spread or infection of the virus. [0003] However, the size of general bacteria is about 1.0 μm to 20 μm, and the size of viruses is usually between 0.3 μm and 0.018 μm. The coronavirus group to which SARS belongs is as small as 0.06 μm to 0.22 μm. It is currently known that the SARS virus is about 0.1 μm, while Commercially available masks have almost no protective effect against viruses below 0.3 μm. And most...

[0003] However, the size of general bacteria is about 1.0 μm to 20 μm, and the size of viruses is usually between 0.3 μm and 0.018 μm. The coronavirus group to which SARS belongs is as small as 0.06 μm to 0.22 μm. It is currently known that the SARS virus is about 0.1 μm, while Commercially available masks have almost no protective effect against viruses below 0.3μm

And most importantly, the general public ignores the characteristics of oral foam transmission. For the users of masks, it is actually a more serious crisis

[0004] Since the SARS virus exists in the droplets (saliva droplets), when the patient's droplets are sprayed on the masks of other people (such as medical personnel), although the masks can block the droplets from being inhaled, this blocking The effect is short-lived, because the water in the droplets will volatilize over time, and when the user breathes, it will form a kind of suction force on the virus particles on the mask, so that the virus particles will gradually lose their moisture attachment. It is inhaled by the user, causing more serious infection, which is the main reason why medical staff are equipped with masks, but still cannot avoid SARS infection (Note: Take the SARS patients in Hong Kong from February 2003 to March 2003 as examples For example, more than 70% of them are medical staff!! Among SARS patients in Taiwan, the proportion of medical staff is gradually increasing!!), so the masks currently on the market cannot provide the most effective prevention effect against SARS
