Who invented the douche?

The precursor to the modern-day douche was invented by Anthony E. Magoris. He called his invention the combined syringe and speculum. He was awarded a patent for it on Mar. 29, 1892.

Magoris obtained patent number 471,647 for the application he filed on Oct. 1, 1891. In his application, he describes his invention as being a device of variable adjusting length that sprays a fine mist from one tube, which then flows back out through a discharge pipe. Countless women have used Magoris' invention since 1892. However, as of 2014, the American College of Obstetricians and Gynecologists and most physicians recommend that women avoid the practice.
