Description

Epidemic prevention gauze mask

Technical Field

The specification relates to the field of articles for daily use and medical supplies, in particular to an epidemic prevention mask.

Background

The novel coronavirus 2019-nCoV and other viruses are mainly transmitted by droplets, aerosols and direct contact, have strong infectivity, can infect respiratory tracts, alveoli and other human mucous membranes to cause pathological changes, cause organ failure of respiratory systems and the like, and finally cause death of critically ill patients. Viral variant vaccines have reduced or no effect as the vaccine responds to the immune system according to the amino acid coding sequence.

Because the ethanol has good inactivation effect on fat-soluble enveloped viruses such as COVID-19 and the like. However, the alcohol concentration in human blood is too high, which can cause poisoning and death, and the concentration required for killing respiratory viruses cannot be reached by drinking spirit. In addition, the trachea and lungs of humans cannot be disinfected with liquid ethanol.

The existing various masks mostly belong to passive protective devices, and can only partially prevent virus from spreading. And the mask used by the patient may become a new source of infection if not handled properly.

SUMMERY OF THE UTILITY MODEL

The embodiment of the specification provides an epidemic prevention mask, which can actively kill various respiratory system viruses such as 2019-nCoV passing through the mask, and improves the epidemic prevention effect of the mask.

The mask provided by the embodiment of the specification is provided with the ethanol interlayer, when a wearer breathes, viruses in the air can be effectively inactivated by the ethanol adsorption interlayer in the mask, meanwhile, the wearer directly inhales volatile ethanol vapor, and when a large number of ethanol molecules are condensed back to a liquid phase on the mucosa surfaces of the trachea, the bronchus and the alveoli of the patient, the required ethanol concentration can be formed in the condensation zone, so that the residual viruses can be inactivated, and the effect of preventing the viruses from entering human cells is achieved. Because the ethanol vapor prolongs the time for the virus to enter the human cells, a small amount of virus enters the human cells, and a template and response time are provided for the human immune system to generate specific response to the virus and kill the virus; avoids the damage caused by the overstimulated immune response of the human immune system to a large number of invading viruses, and the overstimulated immune response is one of the important reasons for the death of the organism organs of the COVID-19 patient due to failure. Meanwhile, the ethanol vapor also changes the protein structure of the virus to inactivate the virus, and finally the virus is killed. The method is expected to be effective for early respiratory system infection caused by fat-soluble coronavirus. And is not affected by virus variation.

Because of the method of inhaling the ethanol vapor by the ethanol-containing interlayer in the mask, diseases caused by COVID-19, SARS virus, H1N1 virus, H5N1 virus, H7N9 virus, Coxsackie virus and various influenza viruses can be inactivated in both inhalation and exhalation directions.
