The origin of tampons can be traced back to 1929. Its inventor is Dr. Earle Cleveland Haas of the United States. Dr. Haas is an ordinary doctor who spends most of his spare time on inventions and creations. At that time, Dr. Haas's wife felt that using thick sanitary napkins for external use brought a lot of inconvenience, so Dr. Haas came up with the idea of ??doing something for his wife. During surgical procedures, doctors or nurses often use cotton or gauze to absorb bleeding. Dr. Haas applied this approach to the use of women's menstrual hygiene products. He invented the world's first internal tampon. Dr. Haas's invention was patented in 1933 and named "TAMPAX". Soon, Danbis internal tampons began to be sold in the U.S. market, and the Danbis brand became famous as the first internal tampon brand.
