Description

Nasal mask

Technical field

The present invention specifically relates to the technical field of sanitary products, in particular to a nasal mask.

Background technique

As humans suffer from bacterial viruses such as SARS, Ebola, swine flu, new coronaviruses, and other viruses, the incidents become more frequent and more extensive and complex. Because of the increasing frequency of people flowing under globalization, the spread of bacteria and viruses is even more frequent. Person-to-person transmission is rapidly spreading globally. As a traditional effective tool to prevent person-to-person transmission, masks have become increasingly important.

However, in addition to the ugly appearance, the use of masks in the hot summer, especially in tropical countries, makes people miserable because of the extremely sultry heat. Moreover, once the sweat on the face flows into the inside of the mask, the risk of the virus invading the respiratory tract through the nostrils is greater than without wearing it.

In addition, the "masking law" promulgated by many western countries for the need of "anti-terrorism" is in vain, and the same high-tech facial recognition technology is automatically invalidated, and it is used in public places such as restaurants, restaurants, and dining halls. For dinners, especially in the confined space of airplane cabins and long-distance trains, high-speed rails, and trains, the masks need to be removed to allow the virus to spread through the respiratory tract.

More importantly, the consumption of discarded masks is extremely high every day, and the damage caused by the secondary damage to the environment is bound to be immeasurable.

During the outbreak of large-scale public health, the use of masks increased sharply, resulting in a serious shortage of raw materials for masks and unable to meet social requirements. The new crown virus pneumonia that broke out in January 2019 caused a serious shortage of core material meltblown cloth, which severely restricted the supply of masks.

In addition, wearing a mask for a long time, because it is in a state of hypoxia in disguise, will definitely cause permanent damage to the lungs and brains of children at the developmental stage. Investigations have shown that the lungs and respiratory system caused by long-term use of masks have caused diseases. more and more. Although the N95 mask has a one-way exhaust valve to prevent exhaust gas from being sucked back, the density of the melt blown cloth of the filtered air is too dense, and the flow of fresh air is too small. Because of insufficient oxygen supply for a long time, chronic damage is formed in disguise. More importantly, N95's one-way valve exhaust gas design has no exhaust disinfection function. While preventing poison, it is also simultaneously spreading poison, which becomes relatively atmospheric purification. And cause harm to the public.

Once the same elderly people wear masks for a long time, they will inevitably accelerate the atrophy and degeneration of brain cells under hypoxia, and accelerate the rejuvenation of Parkinson's dementia symptoms. The prolonged hypoxia of wearing a mask for a long time not only causes lung and respiratory tract diseases and permanent brain damage, but also due to the lack of concentration in class, it will inevitably lead to a decline in academic performance, and the work effectiveness of the same company will also be greatly reduced. .

In the nearly 100-year history of masks, its extremely wasteful disposable anti-virus design, and all of its functions are temporary and short-term "stoppable measures", and it is completely unable to deal with the new crown virus that will be inseparable from human life and death. The traditional masks that have killed a thousand enemies and harmed eight hundred have fallen behind. The breathability is unsatisfactory, and the traditional masks are full of omissions.
