The origin of masks?

It was not seen again in historical records until 1275“Face mask”figure. 'Mark·Paul's Travels records:“In the palaces of the Yuan Dynasty, those who offered food all covered their mouths and noses with silk cloths to keep their breath and not touch the food or drink.”The eunuchs and palace maids who delivered meals to the emperor and queen mother used silk cloth to cover their mouths and noses in order to prevent their breath or saliva from contaminating the master's meals. It is a modern thing that masks are really used in medicine. In 1861, invented“Pasteurization”The French microbiologist Pasteur used a gooseneck flask experiment to prove that there are pathogenic bacteria in the air that can cause various diseases. Despite this conclusion, at the time, doctors did not link breathing to the spread of bacteria, only sterilizing surgical instruments with carbolic acid, and requiring surgeons to wear surgical gowns, surgical caps, and rubber gloves. In the decades that followed, doctors often lived in frustration——The day before, I felt that the operation was very successful, and a piece of carrion was removed from the patient. The next day, I looked at it, alas, why are people dying? After struggling to rescue, the patient was forcibly taken away by death. In 1895, German pathologist Ledecky speculated that the infected saliva of the medical staff caused the infection of the patient's wound. He advised doctors and nurses to wear a gauze mask that covers the nose and mouth during surgery. This move was really effective, and the infection rate of patients' wounds was greatly reduced. Doctors from all over the world followed suit, and masks were popularized in the European medical community. Ledecky's version of the mask, which was nothing more than a layer of gauze smeared over the surgeon's mouth, nose and beard, was tightly packed, uncomfortable, and often wet and dankly stuck to the face. According to the evaluation of many medical staff, the original mask is too low in comfort and needs to be modified urgently. In 1897, a British surgeon installed a thin wire bracket in the gauze, leaving a gap between the gauze and the nose and mouth, overcoming the weakness of poor breathing and being easily wet by saliva. Two years later, the French doctor Paul·Bertie created a 6-ply gauze mask that can be tied freely and comes with a looped strap that can be hung over the ear. The modern mask that is still in use today was born. from“Protect patients from infection”arrive“protect yourself from infection”, the Spanish flu played a key role. During the epidemic, people were forced to wear masks, and some passengers were refused boarding by tram conductors because they did not wear masks. Since then, masks have been widely used in the prevention of respiratory infectious diseases and entered the homes of ordinary people. Tired of wearing medical masks, various fashion brands have launched accessories masks. The labels of camouflage style, industrial style and Harajuku style are printed out, plus a striking brand LOGO, the price can be doubled, and the expensive ones cost four or five hundred yuan. They have a long history and a long-lasting effect: a suitable mask can save you and me from fire and water.
