Description
Technical Field
The utility model relates to a breathe the protection field, especially relate to breathe the external air purifier of lane filtration.
Background
In this epidemic prevention, the infection rate of medical personnel at the epidemic prevention first line and personnel at the epidemic prevention first line is relatively high, and besides the strong infectivity of the new coronavirus, the inherent defects of the current medical protective suit are also the main undeniable reasons. The current medical protective suit comprises a bare surface one-piece medical protective suit, a KN95 medical mask, goggles, a half-helmet transparent mask and the like. Such a suit has the following drawbacks:
the medical protective clothing for the exposed surface is characterized in that although most of a human body is placed under protection, the protective clothing only refers to a protection area, the main channels of the human body infected with viruses are respiratory tracts and naked eye corneas, but are abandoned outside the protective clothing, and the two important parts are protected by a mask and goggles.
Secondly, masks and goggles generally have the defect of close fit with the face of a wearer. Even if the wearer has a good fit in a static state, when the wearer speaks, works, and voluntarily and involuntarily shakes the muscles of the face, it is inevitable that the mask and goggles are not circulated with the outside air within the protection range, thereby failing to protect against viruses.
Thirdly, the air circulation of the KN95 mask is poorer than that of an ordinary medical mask, and the actual fixed duty of the KN95 mask is added, so that a wearer inhales air in the lung every time, the air contains a certain amount of exhaled air, the effective oxygen yield of the wearer is low for a long time, carbon dioxide poisoning of the wearer is caused, or a closed part is unconsciously released in the wearing process to obtain brand new air, and the opportunity is created for virus invasion.
Fourthly, the KN95 mask has poor water vapor permeability, and water vapor contained in human breath is condensed into tiny water drops on the inner wall of the mask, so that the protection of the mask worn for a long time to viruses is reduced.
And fifthly, although the half-helmet type mask can block most of droplets or aerogel containing viruses, a small part of droplets and aerogel still enter the mask to be contacted with the exposed facial skin, the skin of the mask and the goggles which are worn for a long time and the skin of the close position of the human face are pressed, and part of the skin is damaged such as red and swollen skin, so that the opportunity is created for the viruses entering the inside of the half-helmet type mask to invade the damaged skin.
Sixth, in the current medical protective suit, a half-helmet type face mask is configured, and mainly comprises water vapor in gas exhaled through the face mask, and if a full-helmet type helmet is worn, the water vapor can be condensed on transparent glass of the face mask, so that the normal work of a wearer is influenced. While half-helmet masks do not interfere with normal operation due to the air flow between the interior and exterior of the helmet, they also create opportunities for the bare skin of the face to come into contact and become infected with viruses.
Seventh, the integrated open-face medical protective clothing prevents the user from disposing of feces and urine during the wearing time. In fact, the integral protection is not necessary in this new coronavirus protection, but rather a hundred percent protection of the oral mucosa, nasal mucosa and cornea of the eye is absolutely necessary.
Eighthly, the traditional protective clothing has the chance of being infected by a protective object, and if an infected person wears the protective clothing, the virus of the infected person cannot be guaranteed not to spread to the environment.
