Mask is a kind of sanitary product, generally refers to the appliance that is worn on the mouth and nose to filter the air entering the mouth and nose to prevent harmful gases, odors, droplets from entering and leaving the wearer's mouth and nose. It is made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent when working in dust and other polluted environments, wearing masks has a very good effect. Masks can be divided into air filter masks and air supply masks.
China was the first to use masks in the world. In ancient times, people in the palace began to cover their mouth and nose with silk scarves in order to prevent dust and breath pollution. Covering the nose with hands or sleeves is very unhygienic, and it is not convenient to do other things. Later, some people used a piece of silk cloth to cover their mouth and nose. In his book "Marco Polo's Travels", Marco Polo describes his experience of living in China for seventeen years. One of them: "In the palace of the Yuan Dynasty, the people who offered food all used silk cloth to cover their mouth and nose, so as to provide their breath and not touch the food." Such silk cloth for covering the mouth and nose was the original mask.
At the beginning of the 13th century, masks only appeared in the Chinese court. To prevent the breath from reaching the emperor's food, waiters made masks out of a cloth of silk and gold thread.
At the end of the 19th century, masks began to be used in the field of medical care. German pathologist Ledersch began to advise medical staff to use gauze masks to prevent bacterial infections.
At the beginning of the 20th century, masks became a must-have for the public for the first time. The Spanish flu that swept the world claimed the lives of about 50 million people, and the general population was required to use masks to fight off the virus.
In the middle and late 20th century, the number of large-scale use of masks was obviously frequent. In historical pandemics, masks have played an important role in preventing and blocking the spread of germs.
In 1897, the German Midach introduced a method of covering the nose and mouth with gauze to prevent the invasion of bacteria. Later, someone made a six-layer gauze mask and sewed it on the collar. Just turn it over and cover your nose and mouth. However, this kind of mask has to be held down by hand, which is extremely inconvenient. Later, someone thought of using a strap to tie the ears, which has become a mask that people often use today.
In 1910, when the plague broke out in Harbin, China, Dr. Wulien-Teh, then deputy superintendent of Beiyang Army Medical College, invented the "Wu mask".
In 2003, the use and popularization of masks reached a new climax. The SARS epidemic almost made the masks out of stock for a time. There were long lines of people rushing to buy masks in front of major drugstores.
In 2009, following the "bird flu" in 2004, the "H1N1 flu" made the masked army once again appear in front of the cameras of major news media around the world.
The emergence of the concept of PM2.5 air hazards in 2013 has triggered the public's attention to air pollution, making masks and other protective products very popular during haze weather.
