Abstract

The invention discloses a respiratory protection head cover for emergency escape, which comprises a transparent cover body, a window, a fixed head belt, an oronasal cover, a high-efficiency air filter, a talker and a neck fixing ring. The window and the transparent cover body are heat-sealed into a whole, and the oronasal cover and the transparent cover body are heat-sealed and then clamped on the high-efficiency air filter on two sides of the head cover. The front end of the oronasal cover is provided with the talker, the fixed head belt is connected to two sides of the oronasal cover, and the neck fixing ring is heat-sealed at the bottom of the transparent cover body. The respiratory protection head cover for the emergency escape can serve as a respiratory protection article which is light, portable, safe and comfortable for employed persons possibly threatened by biological pollution in occasions including infectious hospitals, emergency and unexpected problem solving, disaster rescue, epidemic prevention protection, border security and the like.

Description

technical field [0001] The invention relates to an emergency evacuation respiratory protective hood, specifically a hood that covers the entire head and provides a higher level of respiratory protection to the head, face and respiratory system by means of self-priming air filtration. Background technique [0002] The aggravation of environmental pollution and the unprecedented increase in the mobility of people in today's world have led to major epidemics such as bird flu and H1N1 influenza, frequent occurrence of sudden public incidents, and the potential threat of bioterrorism attacks, making biological threats a common concern of the whole society. The issues of concern have also expanded from a few areas to almost all areas, including ordinary people. The respiratory tract is the main way for biological hazards to invade the human body, so respiratory protective masks have become the most important biological defense equipment. The existing protective masks at ho...
