Where did the mask come from?
It was not until 1275 that people saw the 'mask' in historical records again. 'Marco Polo's Travel Notes' records: 'In the palace of the Yuan Dynasty, people who offered food used silk cloth to cover their mouths and noses to give their breath and not touch the food.' The eunuch who delivered meals to the emperor and the queen The maid, in order to prevent her breath or saliva from contaminating the master's meals, she covered her mouth and nose with silk cloth. Masks are really used in medicine, it is a modern thing. In 1861, the French microbiologist Pasteur who invented the 'pasteurization method' used a gooseneck flask experiment to prove that pathogenic bacteria exist in the air, which can cause various diseases. Despite this conclusion, at the time, doctors still did not associate breathing with the spread of bacteria. They only used carbolic acid to sterilize surgical instruments, requiring surgeons to wear surgical gowns, surgical caps, and rubber gloves. In the decades that followed, doctors often lived in frustration-the first day they felt that the operation was very successful and cut off a piece of rotten flesh from the patient. The next day I saw, alas, how come people are dying? After struggling to rescue, the patient was forcibly taken away by death. In 1895, German pathologist Ledersch speculated that it was the saliva carried by the medical staff when they were speaking that caused the infection of the patient's wound. He suggested that doctors and nurses wear a mask made of gauze that can cover the nose and mouth during surgery. This move was really effective. The rate of wound infections in patients was greatly reduced. Doctors from all over the world followed suit, and masks were promoted in the European medical community. Lederch's version of the mask is nothing more than a layer of gauze glued to the surgeon's mouth, nose, and beard. It is tightly wrapped, uncomfortable, and it is often wet and sticks to the face damply. After evaluation by many medical staff, the original masks are too comfortable to use and urgently need to be modified. In 1897, a British surgeon installed a thin iron wire bracket in the gauze to leave a gap between the gauze and the nose and mouth, which overcomes the weakness of poor breathing and easy saliva wetness. Two years later, French doctor Paul Bertie invented a 6-layer gauze mask, which can be tied freely and attached with a loop strap that can be hung on the ear. The modern masks that are still in use today were born. From 'protecting patients from infection' to 'protecting oneself from infectionDuring the spread of the epidemic, people were forced to wear masks, and some passengers were refused by the tram conductor because they did not wear masks. Since then, masks have been widely used in preventive measures for respiratory infectious diseases, and have entered the homes of ordinary people. I get tired of wearing medical masks, and various trendy brands have launched accessory masks. Camouflage style, industrial style, Harajuku style labels are printed, plus a striking brand LOGO, the price can be doubled dozens of times, and the expensive one costs four to five hundred yuan. They have a long history and lasting effectiveness: a suitable mask can save you and me from fire and water.
