Description
Technical Field
The invention relates to the technical field of masks, in particular to a resistance-free anti-pollution mask.
Background
At present, the common normal population and the patients with mild symptoms (patients without noninvasive and invasive ventilators) adopt a mask as a general means for preventing diseases from being infected by respiratory tract. Common masks, medical surgical masks and N95 masks, even N99 masks are air inlet and outlet through mask protective covers (except for an exhaust valve), and for patients with dyspnea, the breathing work is further increased, and the dyspnea is obviously aggravated. Meanwhile, the mask can affect the respiratory airflow due to the fact that the face is sealed, and is not beneficial to the elimination of pathogenic microorganisms in the respiratory tract of a patient. In medicine, drainage of pathogenic microorganisms and necrotic tissues is an important treatment means, and the importance of the drainage is not inferior to that of drug treatment means such as antibiotics for killing pathogenic microorganisms. For diseases transmitted by respiratory tract, the exhaled air contains corresponding pathogenic microorganisms, and if the pathogenic microorganisms are discharged outside the exhaled air, the environment is polluted, the diseases are transmitted, the discharge of the diseases is prevented, and the drainage of the pathogenic microorganisms in the lung of a patient is prevented.
In a strict sense, if the mask is completely sealed with the face, breathing is difficult, resistance of about 4 cm of water can be increased, so that children under the age of 7 have suffocation risks, and if the seal is incomplete, air leakage can occur, so that the protective performance of the mask is reduced or even disappears.
