Description

Nose mask with exhaust valve

Technical Field

The application relates to the technical field of medical equipment, in particular to a nasal mask with an exhaust valve.

Background

With the increasing frequency and the wider complexity of the bacterial and viral invasion events of human beings, because of the increasing frequency of people moving in globalization, the spread of bacterial and viral infection is rapidly and globally spread in a person-by-person manner, and the mask is increasingly important as a traditional effective tool for preventing the person-by-person spread.

However, the mask is ugly in appearance, and is used in hot summer, especially in tropical countries, which makes people feel ugly due to abnormal sultriness. In addition, the high-tech technology of face recognition is automatically disabled, and the mask is organically taken off to transmit the virus through the respiratory tract when the people gather in public places such as restaurants, wine houses and dining rooms, particularly airplane cabins in closed spaces and long-distance motor cars, high-speed rails and trains. More importantly, the tremendous waste of lost quantities of astronomical numbers discarded for almost every day replacement and the loss of secondary damage to the environment must be immeasurable.

When the mask is worn for a long time, permanent damage is certainly caused to the lung and the brain of a child in a development stage because the phase change is in an anoxic state, and investigation shows that more and more cases of diseases are caused because the lung and the respiratory system of the child wear the mask for a long time. Although the N95 mask is provided with the one-way exhaust valve to prevent waste gas from being sucked backwards, the flow of sucked fresh air is too small due to the over-dense melt-spray density of filtered air, so that the mask is in an anoxic state for a long time, and the lung and the brain are subjected to phase-change chronic injury due to insufficient oxygen supply for a long time.

Once worn for a long time, the aged people wear the mask, and the aged people are bound to accelerate atrophy and degeneration of brain cells under an anoxic state, so that the dementia symptoms of the aged people with Cupressus are accelerated to be younger. The long-term oxygen deficiency caused by wearing the mask for a long time not only causes diseases of lungs and respiratory tracts and permanent damage to the brain, but also inevitably causes the decline of the learning performance because of the distraction and the difficulty in concentration in class, and the working efficiency of the same enterprises is also greatly reduced.

In the history of the mask in the last hundred years, the extremely wasted disposable gas defense design is provided with no function which is temporary and transient, the traditional mask with poor air permeability is popular, and the traditional mask which is neglected is proved to be untimely, and the historical time that the work is reduced and the change cannot be performed is not subversive and is not slow.
